Description

State control method, control system and related equipment of electric bicycle

This application relates to the field of mobile vehicles, and in particular to a state control method, control system and related equipment for an electric bicycle.

In order to prevent electric bicycles from being lost or other users from using them without permission, electric bicycles need to be locked. Currently, electric bicycles are equipped with mechanical locks or electronic locks to automatically unlock or lock the electric bicycles. Since an extra lock is required on the frame, it takes up space on the electric bicycle and costs more. Moreover, it needs to be operated manually, and it is impossible to achieve the goal of the electric bicycle automatically unlocking or locking when the target user approaches the electric bicycle.

In view of the above, it is necessary to provide a state control method, control system and related equipment for an electric bicycle, so that the electric bicycle can be automatically unlocked or locked without installing an electronic lock or a physical lock, which can reduce the number of components on the electric bicycle and effectively control the weight of the electric bicycle.

The first aspect of the present application provides a state control method for an electric bicycle, comprising: obtaining location information of a target user; generating a state switching instruction according to the location information; and controlling the electric bicycle to switch from an unlocked state to a locked state or from a locked state to an unlocked state according to the state switching instruction.

In this way, the location information of the target user is obtained, a state switching instruction is generated based on the location information, and then the electric bicycle is controlled to switch from an unlocked state to a locked state, or from a locked state to an unlocked state, based on the state switching instruction. The electric bicycle can be automatically unlocked based on the location information of the target user, making it convenient for the target user to use the electric bicycle. Automatically locking based on the location information can prevent the electric bicycle from sending safety hazards. At the same time, there is no need to install an electronic lock or a physical lock, which can reduce the number of components on the electric bicycle and effectively control the weight of the electric bicycle.

As an optional implementation of the first aspect, the location information of the target user sent by the ultra-wideband unit of the electric bicycle is obtained.

In this way, the target user information obtained by the ultra-wideband unit of the electric bicycle is not easily interfered by obstacles, making the positioning more accurate.

In this way, when the distance between the target user and the electric bicycle is outside the preset range, and the direction of the target user relative to the electric bicycle is outside the preset range, a lock command is generated, and the control function control unit is in a closed or standby state, thereby switching the electric bicycle from unlocking to locking. The electric bicycle is locked without feeling, preventing the electric bicycle from being lost and used by other users, reducing safety hazards.

As an optional implementation of the first aspect, controlling the electric bicycle to switch from a locked state to an unlocked state according to the state switching instruction includes: controlling the function control unit of the electric bicycle to be in a wake-up state according to the unlocking instruction, so that the electric bicycle switches from a locked state to an unlocked state. In this way, when the distance between the target user and the electric bicycle is within a preset range, and the direction of the target user relative to the electric bicycle is within a preset range, an unlocking instruction is generated, and the function control unit is controlled to be in a wake-up state, so that the electric bicycle switches from a locked state to an unlocked state. Unlocking the electric bicycle without feeling is convenient for users.

As an optional implementation of the first aspect, the step of obtaining the location information of the target user also includes: obtaining the identity information of the user sent by the low-power Bluetooth unit of the electric bicycle, and verifying whether the user is the target user based on the identity information.

In this way, the user's identity information sent by the low-power Bluetooth unit is obtained, and the user is authenticated as the target user based on the identity information, which ensures that the location information is obtained in a timely manner without affecting the user experience by consuming power due to the need for the ultra-wideband unit to be awakened at all times.

The second aspect of the present application provides a control system for an electric bicycle, the control system comprising a controller, the controller being used to obtain location information of a target user; generate a state switching instruction based on the location information; and control the electric bicycle to switch from an unlocked state to a locked state or from a locked state to an unlocked state based on the state switching instruction.

In this way, the controller obtains the location information of the target user, generates a state switching instruction based on the location information, and then controls the electric bicycle to switch from an unlocked state to a locked state, or from a locked state to an unlocked state according to the state switching instruction. The positioning electric bicycle can automatically unlock according to the location information of the target user, making it convenient for the target user to use the electric bicycle. Automatically locking according to the location information can prevent the electric bicycle from sending safety hazards. At the same time, there is no need to install an electronic lock or a physical lock, which can reduce the number of components on the electric bicycle and effectively control the weight of the electric bicycle.

As an optional implementation of the second aspect, the controller is also used to obtain the location information of the target user sent by the ultra-wideband unit of the electric bicycle.

In this way, the target user information obtained by the ultra-wideband unit of the electric bicycle is not easily interfered by obstacles, making the positioning more accurate.

As an optional implementation of the second aspect, the location information includes the distance between the target user and the electric bicycle, and the controller is further used to generate the unlocking instruction when the distance is within a preset range; and to generate the locking instruction when the distance is outside the preset range.

As an optional implementation of the second aspect, the controller is also used to control the function control unit of the electric bicycle to be in a standby or off state according to the locking instruction to control the electric bicycle to switch from an unlocked state to a locked state; or to control the function control unit of the electric bicycle to be in an awakening state according to the unlocking instruction to switch the electric bicycle from a locked state to an unlocked state.

In this way, when the distance between the target user and the electric bicycle is outside the preset range, and the direction of the target user relative to the electric bicycle is outside the preset range, the controller generates a lock command, and the control function control unit is in a closed or standby state, thereby switching the electric bicycle from unlocked to locked state. The electric bicycle is non-sensingly locked to prevent the electric bicycle from being lost and used by other users, reducing safety hazards. At the same time, when the distance between the target user and the electric bicycle is within the preset range, and the direction of the target user relative to the electric bicycle is within the preset range, the controller generates an unlock command, and the control function control unit is in a wake-up state, thereby switching the electric bicycle from locked to unlocked state. Non-sensing unlocking of electric bicycles is convenient for users.

As an optional implementation of the second aspect, the controller is also used to obtain the user's identity information sent by the low-power Bluetooth unit of the electric bicycle, and authenticate whether the user is the target user based on the identity information.

In this way, the controller obtains the user's identity information sent by the low-power Bluetooth unit and authenticates the user as the target user based on the identity information, ensuring that the location information is obtained in a timely manner without affecting the user experience by consuming power due to the need for the ultra-wideband unit to be awakened at all times.

As an optional implementation of the second aspect, the control system further includes a cycle meter display, which is used to receive the position information and send the position information to the controller, and the cycle meter display and/or the controller are mounted on the handlebar of the electric bicycle.

In order to make the purpose, technical solutions and advantages of this application clearer, the following describes this application in detail with the attached drawings and specific implementation methods. It should be noted that the implementation methods of this application and the features in the implementation methods can be combined with each other without conflict.

In the following description, many specific details are explained to facilitate a full understanding of this application. The implementation methods described are only part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative labor are within the scope of protection of this application.

Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by technicians in the technical field of this application. The terms used in this application specification are only for the purpose of describing specific implementation methods and are not intended to limit this application.

In order to accurately describe the technical content of this application and to accurately understand this application, the following explanations or definitions are given for the terms used in this specification before describing the specific implementation methods.

Ultra-Wideband (UWB) is a secure ranging and positioning technology based on pulsed radio. It can use time of flight (ToF) to safely and accurately calculate the relative position between UWB-enabled devices. Specifically, when multiple UWB devices are close to each other, they use ToF measurements to calculate the round-trip time of communication. Therefore, one device can immediately and continuously calculate the relative position of another device, with an update rate of 100 times per second, so that the real-time position of both devices can be monitored immediately. UWB uses a spectrum of 3.1GHz to 10.6GHz, with a channel bandwidth of up to 500MHz and a pulse as short as 2 nanoseconds (ns).

The electric bicycle controller is used for users to operate and control the electric bicycle to achieve corresponding functions. For example, users can use the electric bicycle controller to control the auxiliary power of the electric bicycle, adjust the lighting mode of the headlights, the gear position of the gearshift, and switch the interface of the display terminal on the electric bicycle. The display terminal may include a digital display and a mobile phone. This application will refer to the electric bicycle controller as the controller.

The speedometer display is used to display information about the electric bicycle and the user, as well as the operation signals input by the user. The speedometer display can be optionally installed on the electric bicycle by the user as needed.

Below is a brief description of the relevant technologies.

In order to prevent electric bicycles from being lost or other users from using them without permission, electric bicycles need to be locked. Currently, electric bicycles are equipped with mechanical locks, which are opened or closed with a physical key, thereby locking or unlocking the electric bicycle. Alternatively, an electronic lock can be installed on an electric bicycle, and the Bluetooth wireless communication technology can be used to connect to a mobile phone with an application (APP) for unlocking the electronic lock, and the electronic lock can be opened or closed using the APP. Alternatively, a device with a virtual key can be prepared and installed using near field communication technology, and when the device touches the electronic lock, the electronic lock is opened or closed, thereby making the electric bicycle unlocked or unlocked. However, it is not easy to open or close the electronic lock accurately in a timely manner when using the mobile phone APP to open or close the electronic lock, because the Bluetooth signal is easily interfered with, and the accuracy of the positioning information of the electronic lock received by the mobile phone is relatively poor. To open or close the electronic lock using near field communication technology, the device with the virtual key installed needs to be in direct contact with the electronic lock. The three current methods of unlocking or locking an electric bicycle all require an additional lock on the frame, which takes up space on the electric bicycle and costs more. They also all require manual operation, and cannot achieve the goal of the electric bicycle automatically unlocking or locking when the user approaches the electric bicycle.

To this end, this application provides a state control method, control system, electronic equipment and storage medium for an electric bicycle, which can realize automatic unlocking or locking of the electric bicycle without installing an electronic lock or a physical lock, thereby reducing the number of components on the electric bicycle and effectively controlling the weight of the electric bicycle.

Please refer to FIG. 1, which is a schematic diagram of an application scenario of an electronic device in the embodiment of the present application. The electronic device may be a controller 2. An ultra-wideband unit is installed on the electric bicycle. The ultra-wideband unit may be integrated into the controller 2 or the meter display 3. When the target user brings the ultra-wideband-supporting device 1 close to the electric bicycle, the ultra-wideband unit of the electric bicycle may continuously calculate the location information of the target user and send the location information of the target user to the controller 2. The controller 2 controls the electric bicycle to switch from an unlocked state to a locked state or from a locked state to an unlocked state according to the location information.

Please refer to Figure 2, which is a schematic diagram of the process of the state control method of the electric bicycle in the implementation method of this application. The method can be applied to electronic equipment. The state control method of the electric bicycle may include:

Step S101: Obtain the location information of the target user; the electronic device is illustrated by the controller 2 shown in FIG. 1 . The target user refers to a user who has the right to use an electric bicycle and carries a device that supports positioning, such as a device 1 that supports ultra-wideband. The electric bicycle is equipped with a controller 2 and a positioning unit that can receive the location information of the target user. The positioning unit may include a Wi-Fi (Wireless Fidelity, Wi-Fi) unit, a Bluetooth Low Energy (Bluetooth Low Energy, BLE) unit, a Near Field Communication (Near Field Communication, NFC) unit, and an ultra-wideband unit. When the target user carries the device 1 that supports ultra-wideband close to the electric bicycle, the positioning unit of the electric bicycle can continuously calculate the location information of the target user. And send the location information to the controller 2. The ultra-wideband-capable device 1 may include a smartphone, a wearable device, a key, a tag, and a door lock.

When the target user brings the ultra-wideband-capable device 1 close to the electric bicycle, the positioning unit of the electric bicycle can continuously calculate the location information of the target user and send the location information to the controller 2.

Step S102: Generate a state switching instruction based on the location information; the state switching instruction includes an unlock instruction and a lock instruction, the unlock instruction refers to switching the electric bicycle from a locked state to an unlocked state, and the lock instruction refers to switching the electric bicycle from an unlocked state to a locked state. The unlocked state of the electric bicycle means that each unit of the electric bicycle is in an awakened state, and each unit can respond to the user's operation in time. The locked state of the electric bicycle means that each unit of the electric bicycle is in a standby or closed state, that is, when the user operates each unit, it is necessary to wait for each unit to be awakened and cannot respond to the user's operation in time. The various units of the electric bicycle include the units of the electric bicycle itself, such as the battery, power control unit, gearshift, motor and electric current sensor of the motor, etc., and also include the units connected to the electric bicycle by physical wired connection or wireless connection, such as the controller 2, digital display, mobile phone and headlights, etc.

After the controller 2 obtains the location information of the target user using the positioning unit, it generates an instruction to switch the unlocked state of the electric bicycle to the locked state, or to switch the locked state to the unlocked state according to the location information.

Step S103: Control the electric bicycle to switch from an unlocked state to a locked state or from a locked state to an unlocked state according to the state switching instruction.

The controller 2 sends an unlocking command to each unit of the electric bicycle, and each unit switches from a standby or closed state to a wake-up state, thereby switching the electric bicycle from a locked state to an unlocked state. After sending a locking command to each unit of the electric bicycle, each unit switches from a wake-up state to a standby or closed state, thereby switching the electric bicycle from an unlocked state to a locked state.

In an application scenario, the electric bicycle is in a locked state. The target user brings the ultra-wideband-supported device 1 close to the electric bicycle equipped with a positioning unit. The positioning unit sends the acquired location information to the controller 2. The controller 2 generates an unlocking command based on the location information. The unlocking command is sent to the function control unit of the electric bicycle, so that each unit is in an awakened state, thereby controlling the electric bicycle to unlock.

In an application scenario, the electric bicycle is in an unlocked state. The target user carries the ultra-wideband-supported device 1 away from the electric bicycle equipped with a positioning unit. The positioning unit sends the acquired location information to the controller 2. The controller 2 generates a lock command based on the location information. The lock command is sent to the function control unit of the electric bicycle, so that each unit is in a standby or closed state, thereby controlling the electric bicycle to lock.

Understandably, after the positioning unit calculates the location information of the target user, it sends the location information to the controller 2. The controller 2 generates a state switching instruction based on the location information, and then controls the electric bicycle to switch from unlocked to locked state, or from locked to unlocked state according to the state switching instruction. The electric bicycle can be automatically unlocked according to the location information of the target user, which is convenient for the target user to use the electric bicycle. It can be automatically locked according to the location information to prevent the electric bicycle from being lost. At the same time, there is no need to install an electronic lock or a physical lock, which can reduce the number of components on the electric bicycle and effectively control the weight of the electric bicycle.

In this way, the location information of the target user is obtained, a state switching instruction is generated based on the location information, and then the electric bicycle is controlled to switch from an unlocked state to a locked state, or from a locked state to an unlocked state according to the state switching instruction. The positioning electric bicycle can be automatically unlocked according to the location information of the target user, which is convenient for the target user to use the electric bicycle. Automatic locking according to the location information can prevent the electric bicycle from sending safety hazards. At the same time, there is no need to install an electronic lock or a physical lock, which can reduce the number of components on the electric bicycle and effectively control the weight of the electric bicycle.

As an optional implementation, the positioning unit can be an ultra-wideband unit. When the target user carries the ultra-wideband-enabled device 1 close to the electric bicycle, the ultra-wideband unit of the electric bicycle can continuously calculate the location information of the target user and send the location information to the controller 2.

Understandably, the method of using the received signal strength indication (RSSI) of Wi-Fi units, low-power Bluetooth units, and near-field communication units to determine the signal strength and then calculate the distance and position between multiple devices is susceptible to relay attacks from unauthorized remote users, resulting in inaccurate calculations. However, using the ultra-wideband unit to locate the location information of the target user can detect whether the device emitting ToF is a neighboring device to prevent relay attacks, thereby more accurately calculating the distance and position between devices. At the same time, since the RSSI positioning unit is easily affected by obstacles, resulting in attenuation of the received signal strength, and is sensitive to multipath, it is easy to reduce the positioning accuracy. Due to the high bandwidth and short pulse characteristics of UWB, positioning using UWB units can maintain low latency (<10ms) and high performance in multi-path situations. At the same time, the ToF measurement method of UWB units is not easily interfered by obstacles, making positioning more accurate. Because UWB uses the 3.1GHz to 10.6GHz spectrum, it is far away from the 2.4GHz band used by other units, making UWB less susceptible to interference when used in conjunction with Wi-Fi (Wireless Fidelity, Wi-Fi) units, Bluetooth (Bluetooth) units, and Near Field Communication (Near Field Communication, NFC) units.

In this way, the target user information obtained by the ultra-wideband unit of the electric bicycle is not easily interfered by obstacles, making the positioning more accurate.

As an optional implementation, the location information includes the distance between the target user and the electric bicycle and/or the direction of the target user relative to the electric bicycle.

The UWB unit can measure any direction of 360° with the UWB unit as the center, and can also measure the range of 1cm to 10m with the UWB unit as the starting point. The measurement accuracy of the UWB unit can reach about 1cm. Developers can set the range of target user detection as needed. In other words, when the target user enters the preset range, he will be detected by the UWB unit on the electric bicycle.

As an optional implementation method, step S102 may also include:

Step S201: When the distance is within the preset range, an unlock command is generated; when the location information shows that the distance between the target user and the ultra-wideband unit on the electric bicycle is within the preset range, such as 1m, 1.2m and 1.5m. And/or the location information also shows that the direction of the target user on the electric bicycle is also within the preset range, such as a certain direction of the ultra-wideband unit is preset as a baseline, and the base line is rotated clockwise or counterclockwise by 0°~160° or 0°~180°. The controller 2 generates an unlock command according to the location information.

The function control unit refers to the unit that can realize various functions on the electric bicycle, that is, the units in step S102.

Step S202: Control the function control unit of the electric bicycle to be in an awake state according to the unlocking instruction, so that the electric bicycle switches from the locked state to the unlocked state.

For example, the unlocking command is sent to the battery, power control unit, transmission, motor, electric current sensor of the motor, controller 2, digital display, mobile phone and car lights, so that these functional control units are in an awake state.

In an application scenario, the controller 2 sends the generated unlocking command to the sub-unit of the controller 2, and the sub-unit of the integrated controller 2 is awakened. The sub-unit of the integrated controller 2 includes an input unit, a storage unit, and a communication unit. Therefore, when the target user enters the preset range, the controller 2 can be directly operated to realize the corresponding electric bicycle function.

In an application scenario, the controller 2 sends the generated unlocking command to the power control unit. After the power control unit is awakened, the power control unit controls the motor and the related current sensor of the motor is also awakened. Therefore, when the target user enters the preset range, the electric bicycle can be directly driven forward.

Understandably, when the distance between the target user and the electric bicycle is within a preset range, and/or the direction of the target user relative to the electric bicycle is within a preset range, the controller 2 generates an unlocking instruction and controls the function control unit to be in an awakening state, thereby switching the electric bicycle from a locked state to an unlocked state. Unlocking the electric bicycle without feeling is convenient for users.

Thus, when the distance between the target user and the electric bicycle is within a preset range, and/or the direction of the target user relative to the electric bicycle is within a preset range, the controller 2 generates an unlocking command and controls the function control unit to be in an awakening state, thereby switching the electric bicycle from a locked state to an unlocked state. Unlocking the electric bicycle without feeling is convenient for users.

As an optional implementation method, step S102 may also include:

Step S301: When the direction and distance are outside the preset range, a lock command is generated; when the location information shows that the distance between the target user and the ultra-wideband unit on the electric bicycle is outside the preset range, such as 1m, 1.2m and 1.5m. And/or the location information also shows that the direction of the target user on the electric bicycle is also inside or outside the preset range, such as when a certain direction of the preset ultra-wideband unit is rotated clockwise or counterclockwise around the baseline by 0°~160° or 0°~180°. The controller 2 generates a lock command according to the location information.

Step S302: Control the function control unit of the electric bicycle to be in a standby or closed state according to the locking command to control the electric bicycle to switch from the unlocking state to the locking state.

For example, a lock command is sent to the battery, power control unit, transmission, motor, electric current sensor of the motor, controller 2, digital display, mobile phone and headlights, so that these functional control units are in standby or off state.

In one example, the controller 2 sends the generated lock command to the sub-unit of the controller 2, and the sub-unit of the integrated controller 2 is in a standby or closed state. The sub-unit of the integrated controller 2 includes an input unit, a storage unit, and a communication unit. Therefore, when the target user is outside the preset range, the controller 2 cannot respond to the operation of other users, thereby controlling the electric bicycle to be in a locked state.

In one example, the controller 2 sends the generated unlocking command to the power control unit, the power control unit is in a standby or off state, and the power control unit controls the motor and the related electric current sensor of the motor to be in a standby or off state. Therefore, when the target user is outside the preset range, other users cannot directly drive the electric bicycle forward, thereby controlling the electric bicycle to be in a locked state.

Understandably, when the distance between the target user and the electric bicycle is outside the preset range, and the direction of the target user relative to the electric bicycle is outside the preset range, the controller 2 generates a lock command, and controls the function control unit to be in a closed or standby state, thereby switching the electric bicycle from unlocking to locking. The electric bicycle is locked without feeling, preventing the electric bicycle from being lost and used by other users, reducing safety hazards.

In this way, when the distance between the target user and the electric bicycle is outside the preset range, and the direction of the target user relative to the electric bicycle is outside the preset range, the controller 2 generates a lock command, and controls the function control unit to be in a closed or standby state, thereby switching the electric bicycle from unlocking to locking. The electric bicycle is locked without feeling, preventing the electric bicycle from being lost and used by other users, reducing safety hazards.

As an optional implementation method, the step before step S101 may include:

Step S401: Obtain the user's identity information sent by the low-power Bluetooth unit of the electric bicycle, and authenticate the user as the target user based on the identity information.

The user needs to carry a device that supports ultra-wideband in order to switch the electric bicycle between unlocked and locked states. Each device that supports ultra-wideband has a corresponding carrier, so by obtaining the identity information of the device that supports ultra-wideband, it can be determined whether the carrier is the target user. The identity information includes the device information of the ultra-wideband device and the electric bicycle and the generated password. The electric bicycle can be equipped with a low-power Bluetooth unit for authenticating the user's identity, and the low-power Bluetooth unit can be integrated into the controller 2.

For example, the method of identity authentication between the controller 2 and the ultra-wideband device 1 may include: first, the controller 2 and the ultra-wideband device 1 are both equipped with low-power Bluetooth units to establish a Bluetooth connection. When the controller 2 finds that the ultra-wideband device 1 enters the Bluetooth broadcast range, it exchanges identity information with the ultra-wideband device 1 and binds the identity information of the ultra-wideband device 1 to complete the identity authentication between the controller 2 and the ultra-wideband device 1. When the ultra-wideband device 1 enters the Bluetooth broadcast range again, the controller 2 does not need to bind the identity with the ultra-wideband device 1, and can directly confirm that the user of the ultra-wideband device 1 is the target user.

After authenticating the user as the target user, the controller 2 wakes up the ultra-wideband unit on the electric bicycle so that the ultra-wideband unit calculates the location information of the target user.

Understandably, the controller 2 uses the UWB unit in combination with the LE Bluetooth unit to automatically measure the target user's location information after the target user of the electric bicycle is authenticated. LE Bluetooth is a low-power technology that can extend the battery life. The UWB unit is awakened only when needed, ensuring that the location information is obtained in a timely manner without affecting the user experience by consuming power due to the need for the UWB unit to be awakened at all times.

Please refer to FIG. 3 . The present application further provides a control system 100 for an electric bicycle. The control system 100 includes a controller 2. The controller 2 includes a central processing unit 10. The central processing unit 10 may be a microcontroller unit (MCU) or a central processing unit (CPU). The central processing unit 10 is used to obtain the location information of the target user. In an optional implementation, the central processing unit 10 is used to obtain the location information of the target user sent by the ultra-wideband unit of the electric bicycle. A state switching instruction is generated according to the location information, and the electric bicycle is controlled to switch from an unlocked state to a locked state or from a locked state to an unlocked state according to the state switching instruction. The central processing unit 10 is also used to generate an unlocking instruction when the distance is within a preset range, and control the function control unit of the electric bicycle to be in an awake state according to the unlocking instruction, so that the electric bicycle switches from a locked state to an unlocked state. When the distance is outside the preset range, a locking instruction is generated, and the function control unit of the electric bicycle is controlled to be in a standby or closed state according to the locking instruction, so as to control the electric bicycle to switch from an unlocked state to a locked state. The central processing unit 10 is also used to obtain the identity information of the user sent by the low-power Bluetooth unit of the electric bicycle, and authenticate whether the user is a target user according to the identity information.

That is to say, the central processing unit 10 of the controller 2 is used to implement part or all of the steps of the state control method of the electric bicycle of the present application. The specific content can be found in the discussion of the state control method of the electric bicycle, which will not be repeated here. At the same time, the central processing unit 10 can also respond to the user's operation signal to generate corresponding function control instructions to realize various functions on the electric bicycle.

Please refer to Figure 9. The ultra-wideband unit 20 of the computer display 3 sends the position information to the central processing unit 10 of the controller 2 via the physical wire. After the central processing unit 10 sends the unlocking command to the power control unit 4 via the physical wire, the power control unit 4 is awakened and controls the motor and the related electromagnetic flow sensor of the motor to be in the awakened state.

When the target user moves away from the electric bicycle, the central processing unit 10 of the controller 2 on the electric bicycle determines that the user is outside the detection range based on the location information sent by the ultra-wideband unit 20 of the computer display 3. The central processing unit 10 of the controller 2 sends an unlock command to the function control unit 30 in the controller 2, such as the input unit 31, the communication unit 32 and the storage unit 33, and other function control units 30 outside the controller 2, such as the power control unit 4, the headlights, etc., to control the input unit 31, the communication unit 32, the storage unit 33, the power control unit 4 and the headlights to be in a closed or standby state. Among them, the ultra-wideband unit 20 of the computer display 3 sends the position information to the central processing unit 10 of the controller 2 via the physical wire. After the central processing unit 10 of the controller 2 sends the unlocking command to the power control unit 4 via the physical wire, the power control unit 4 is awakened and controls the motor and the related electromagnetic flow sensor of the motor to be in the awakened state.
