Description

Vehicle fuel quantity detection system, vehicle fuel quantity detection method and mobile device

The invention relates to a vehicle fuel quantity detection system, a vehicle fuel quantity detection method and a mobile device, and in particular relates to a vehicle fuel quantity detection system and a vehicle fuel quantity detection method which can more accurately measure the fuel quantity and Mobile device.

The current vehicle fuel tank detection system usually uses a traditional float to calculate the voltage. The up and down of the buoy allows the owner to know the current amount of fuel in the tank, but this data is often not so accurate. Whether the pointer instrument panel or the electronic instrument panel shows the first fuel volume, it can always be used for the longest time, making most people think that the first fuel can be used for the longest time after the gasoline is full. This is because the electronic detection position on the float is in the center of the float. As shown in FIG. 1, when the fuel tank 100 is filled with oil, the buoy 110 floats above the fuel tank 100. The detection position of the electronic sensor 120 of the pontoon 110 is located in the center of the pontoon 110, which causes the pontoon 110 to fail to accurately detect the amount of oil in the section 130 in the tank 100. In addition, the buoy 110 cannot detect the amount of oil in the oil pipe 140. Therefore, how to more accurately measure the amount of oil is a goal that those skilled in the art should strive for.

When the difference between the instant total mileage and the historical total mileage is less than the threshold, the mobile device determines whether the instant fuel quantity is greater than the first threshold and the latest historical fuel quantity is less than the second threshold. If the immediate fuel quantity is greater than the first threshold value and the latest historical fuel quantity is less than the second threshold value, the mobile device sets the current fuel quantity to the fuel tank trip fuel quantity.

In an embodiment of the present invention, when the difference between the instant total mileage and the historical total mileage is not less than the threshold, the mobile device determines whether the instant fuel quantity is greater than the first threshold. If the instant fuel quantity is greater than the first threshold, the mobile device sets the current fuel quantity to the average of the fuel tank trip fuel quantity and the first grid fuel quantity.

The invention provides a mobile device coupled to a vehicle. The mobile device receives instant fuel quantity and instant total mileage. The mobile device determines whether the difference between the real-time total mileage and the historical total mileage stored in the mobile device is less than the threshold.

If the instant fuel quantity is greater than the first threshold value and the latest historical fuel quantity is less than the second threshold value, it means that the user has just added fuel, and the mobile device sets the current fuel quantity to the fuel tank trip fuel quantity.

In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.

2 is a block diagram of a vehicle fuel quantity detection system according to an embodiment of the invention.

2, a vehicle warning system 200 according to an embodiment of the present invention includes a vehicle 210 and a mobile device 220 coupled to the vehicle 210. Both the vehicle 210 and the mobile device 220 may have a processor (not shown in the figure) and a communication chip (not shown in the figure). The vehicle 210 may be a transportation vehicle such as an oil truck, an electric vehicle, a locomotive, and an automobile. The processor of the vehicle 210 can collect vehicle information such as engine speed, engine temperature, mileage information, and fuel consumption information. The mobile device 220 may be a portable electronic device such as a smart phone, a notebook computer, a tablet computer, a smart watch, and a smart bracelet.

The processors of the vehicle 210 and the mobile device 220 may be a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessors (Microprocessor), digital signal processors (Digital Signal Processor) , DSP), programmable controller, application specific integrated circuit (Application Specific Integrated Circuit, ASIC) or other similar components or combinations of the above components, the disclosure is not limited thereto.

The communication chips of the vehicle 210 and the mobile device 220 can be Global System for Mobile Communication (GSM), Personal Handy-phone System (PHS), and Code Division Multiple Access. CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, Long Term Evolution (LTE) system, Worldwide Interoperability for Microwave Access (WiMAX) system, wireless fidelity (Wireless Fidelity, Wi-Fi) system or Bluetooth signal transmission components or other similar components.

When the electric door of the vehicle 210 is opened, the vehicle 210 is coupled to the mobile device 220 and transmits the electric door opening signal to the mobile device 220. Specifically, the electric door opening may be a state in which the key is inserted into the key hole of the vehicle 210 and the key is turned to open the electric door (or simultaneously open the instrument panel of the vehicle 210). After the electric valve is turned on and before the engine is started, the user cannot operate the accelerator to move the vehicle 210. The user must press the start button (or press the brake at the same time) after the electric door is opened to enter the engine start state. The vehicle 210 may be paired with the mobile device 220 in advance, and when the electric door of the vehicle 210 is opened, it is coupled to the mobile device 220 through Bluetooth communication (or other communication methods). When the electric door of the vehicle 210 is opened, the vehicle 210 can send the electric door opening signal to the application of the mobile device 220, and access the real-time information and/or historical information of the vehicle 210 through the application.

When the electric door of the vehicle 210 is opened, the vehicle 210 will further transmit the instant fuel quantity and the instant total mileage to the mobile device 220. The amount of oil in the tank will be inversely proportional to the voltage of the tank. For example, the fuel tank trip volume is 5700 ml, the first tank oil volume is 4700 ml and the corresponding voltage value is 1.1 volts (V), the second tank oil volume is 4000 ml and the corresponding voltage value is 1.58 volt.

After receiving the instant total mileage, the mobile device 220 further determines whether the difference between the instant total mileage and the historical total mileage stored in the mobile device 220 is less than the threshold. The threshold value is, for example, 500 meters. If the difference between the instant total mileage and the historical total mileage is greater than the threshold value, it means that the vehicle 210 has been ridden by another user, or the user has operated the cart in the power-off state, or the mileage-related sensor is damaged.

When the difference between the instant total mileage and the historical total mileage is less than the threshold, the mobile device 220 determines whether the instantaneous fuel quantity is greater than the first threshold (ie, the fuel quantity is greater than the first grid fuel quantity) and the latest historical fuel quantity is less than the second threshold Value (ie, the amount of oil is less than the amount of oil in the second compartment). To illustrate with the above example, the mobile device 220 determines whether the real-time oil volume is greater than 4700 ml and the last historical oil volume data is less than 4000 ml. The last historical oil quantity data is less than 4000 ml and the real-time oil quantity is greater than 4700 ml. This means that the user opens the electric switch for the first time after refueling. Therefore, the mobile device 220 sets the current oil quantity to 5700 ml. If the current fuel quantity is not greater than the first threshold value or the latest historical fuel quantity is not less than the second threshold value, the mobile device 220 directly sets the current fuel quantity to the fuel quantity measurement value corresponding to the tank voltage value. After the mobile device 220 obtains the current fuel amount, the mobile device 220 may calculate the range that can be driven based on the current fuel amount and the historical average fuel consumption.

It is worth noting that in the above embodiment, the first threshold value corresponds to the first grid oil amount and the second threshold value corresponds to the second grid oil amount, but the invention is not limited thereto. In another embodiment, the first threshold value may be defined as the relationship between the fuel tank voltage value and the oil quantity begins to decrease in resolution when the oil quantity is above the first threshold value (ie, the oil quantity is within the first threshold value) When going up, the fuel volume will increase only if the fuel tank voltage value increases a lot. The non-linearity of the fuel tank voltage value relative to the fuel volume becomes serious (ie, the extent to which the fuel tank voltage value decreases when the fuel volume is above the first threshold) Is not proportional to the amount of oil increase), or the tank voltage value is the same voltage value as the oil amount saturation (ie, when the oil amount is above the first threshold, even if the oil amount increases, the tank voltage value will remain at a The saturation voltage value does not move). In addition, the second threshold value does not necessarily correspond to the second oil quantity, but may correspond to other oil quantity values.

When the difference between the instant total mileage and the historical total mileage is not less than the threshold value, the mobile device 220 determines whether the instant fuel quantity is greater than the first threshold value (ie, the fuel quantity is greater than the first grid fuel quantity). If the instant fuel quantity is greater than the first threshold, the mobile device 220 sets the current fuel quantity to the average of the tank trip fuel quantity and the first grid fuel quantity (for example, the average of 5700 ml and 4700 ml). If the instantaneous fuel quantity is not greater than the first threshold, the mobile device 220 directly sets the current fuel quantity as the current fuel quantity measurement value. After the mobile device 220 obtains the current fuel amount, the mobile device 220 may calculate the range that can be driven based on the current fuel amount and the historical average fuel consumption. Specifically, when the current fuel quantity is greater than the first threshold value, the mobile device 220 updates the current fuel quantity according to the immediate fuel consumption, and calculates the driving range according to the updated current fuel quantity and the historical average fuel consumption. When the current fuel quantity is not greater than the first threshold value, the mobile device 220 obtains the instantaneous remaining fuel quantity according to the fuel tank voltage value of the vehicle 210, and calculates the driving range according to the instantaneous remaining fuel quantity, that is, the historical average fuel consumption.

When the difference between the instant total mileage and the historical total mileage is less than the threshold value, in step S304, the mobile device determines whether the instant fuel quantity is greater than the first threshold value and the latest historical fuel quantity is less than the second threshold value.

If the current fuel quantity is greater than the first threshold value and the latest historical fuel quantity is less than the second threshold value, in step S305, the mobile device sets the current fuel quantity to the fuel tank trip fuel quantity.

If the current fuel quantity is not greater than the first threshold value or the latest historical fuel quantity is not less than the second threshold value, then in step S306, the mobile device sets the current fuel quantity as the current fuel quantity measurement value.

When the difference between the instant total mileage and the historical total mileage is not less than the threshold value, in step S307, the mobile device determines whether the instant fuel amount is greater than the first threshold value.

If the instantaneous fuel quantity is greater than the first threshold value, in step S308, the mobile device sets the current fuel quantity to the average of the fuel tank trip fuel quantity and the first grid fuel quantity.

If the instant fuel quantity is not greater than the first threshold value, in step S309, the mobile device sets the current fuel quantity as the current fuel quantity measurement value.

Finally, in step S310, the mobile device calculates the driving range based on the current fuel quantity and the historical average fuel consumption.

If the difference between the real-time total mileage and the historical total mileage is less than the threshold value, it means that the mileage data is continuous data, then it is further determined whether the real-time fuel quantity is greater than the first threshold value and the latest historical fuel quantity is less than the second threshold value, that is, to determine whether the historical oil quantity The quantity data is less than the second fuel volume and the real-time fuel quantity is greater than the first fuel volume. This situation occurs when the user first turns on the electric valve after refueling. If the instant fuel quantity is greater than the first threshold value and the latest historical fuel quantity is less than the second threshold value, it means that the user has just added fuel, and the mobile device sets the current fuel quantity to the fuel tank trip fuel quantity.
