Description

Tire pressure sensor position input method

The invention relates to the setting of a tire pressure sensor, in particular to a tire pressure sensor position input method.

At present, the position of the tire pressure sensor is set by first switching the receiving host on the vehicle into the learning mode, and then according to the receiving order required by the receiving host, for example, the right front wheel, the left front wheel, the right rear wheel, the left rear wheel, and the like. Triggering the tire pressure sensor installed in the tire, after receiving the signal from the first tire pressure sensor, the receiving host will remember the ID of the tire pressure sensor at the position and then enter Waiting to receive the second protocol, so back and forth to the receiving host to complete the learning of all tire positions. In order to make the tire pressure sensor emit a signal, the tire is deflated, so that the tire pressure sensor will send a signal when the pressure of the tire is lower than a predetermined warning value, but such operation is cumbersome because The user must deflate one tire and one wheel and then pump one tire and one tire to return the tire to normal tire pressure after the receiving host learns. Furthermore, such a setting mode is only limited to the setting of the tire pressure sensor ID and the position, and the warning value for other detecting factors such as temperature or pressure cannot be set by this method. Therefore, it is necessary to provide a different way of learning settings.

In view of the above-mentioned deficiencies, the object of the present invention is to provide a quick and simple operation method for inputting the position of the tire pressure sensor, so that the user can no longer need to deflate the tire when setting the position of the tire pressure sensor and the tire. .

Another object of the present invention is to provide a tire pressure sensor and wheel that can be set The tire pressure sensor position input method of setting the warning temperature value and pressure value together with the corresponding position of the tire.

In order to achieve the above object, the tire pressure sensor position input method of the present invention is to select a position of a tire pressure sensor to be set by using an operation interface of the setting tool, and then a trigger signal is sent by the setting tool. The tire pressure sensor in the tire is triggered, and after the tire pressure sensor receives the trigger signal, a reply signal is returned, and the reply signal includes the ID of the tire pressure sensor. After receiving the ID returned by the tire pressure sensor, the setting tool encodes the parameters of the tire pressure sensor ID and the selected position to be set to a receiving code.

The first figure is a flow chart of the operation of the tire pressure sensor ID and position setting according to the present invention.

The second figure is a flow chart of the setting tool transmission setting code of the present invention.

The technical contents and features of the present invention will be described in detail below with reference to the accompanying drawings.

Referring to the first figure, the method for inputting the position of the tire pressure sensor according to the present invention is as follows: A provides a setting tool, and the setting tool comprises a micro processing unit, a memory, a display interface and an operation interface.

B Use the operation interface of the setting tool to select the position of the tire pressure sensor to be set, the temperature value of the warning, and the pressure value of the warning. For example, select the tire to be set as the left front wheel, the warning temperature value is 150 degrees, and the pressure warning value is 15 psi.

C. Set the setting tool close to the tire to be set (for example, the left front wheel). The setting tool wirelessly emits a trigger signal to trigger the tire pressure sensor in the left front wheel.

After receiving the trigger signal, the D tire pressure sensor will return a reply signal, and the reply signal includes the ID of the tire pressure sensor.

After receiving the ID returned by the tire pressure sensor, the E setting tool temporarily stores the ID of the tire pressure sensor in the memory of the setting tool.

The micro-processing unit of the F setting tool encodes the received tire pressure sensor ID, the selected position to be set, the temperature and pressure value to be alerted, and the like.

Repeat steps B~F until the ID of the tire inner tire pressure sensor to be set is obtained by the setting tool and the ID and corresponding position of each tire pressure sensor have also been designated. For example, if there are four tires to be set, the steps B~F are performed four times. At this time, all the setting values of the tire pressure sensor ID, warning temperature, warning pressure, etc. are set and stored in the setting tool. This setting tool. The micro-processing unit of the setting tool will encode the received tire pressure sensor ID, the selected position to be set, the temperature and pressure value to be alerted into a setting code, so there are four tire positions to set the setting. The tool will compile four different setup codes.

The setting operation of the aforementioned position, the warning temperature value and the warning pressure value are not sequential, and the warning temperature value may be set first, then the position is set, the warning pressure value or the warning pressure value is set, and the warning temperature value is set again. position.

By the above method, the operator only needs to hold the setting tool to walk around the car one turn of the setting tool to complete the reading operation corresponding to the position of all the tire inner tube pressure sensor ID.

After the setting tool obtains the relevant parameters and completes the setting code, the completed setting data value is input to the receiving host on the vehicle by setting the receiving host on the vehicle to the learning mode.

The setting code is wirelessly transmitted to the receiving host on the vehicle by the setting tool.

The receiving host receives the setting code and stores it in the receiving host.

When the receiving host receives the completion, it will reply a completion signal to the setting tool, and then the receiving host will switch from the learning mode to the normal mode.

The foregoing setting of the setting code into the receiving host of the vehicle does not necessarily have to be transmitted together after all the positions and ID reading settings are completed, or may be transmitted to the receiving host once for each setting code.

The program format of the setting code transmitted by the setting tool to the receiving host may be according to the program format received by the receiving host, or may be a specific program format between the setting tool and the receiving host.

In the method of the present invention, the operator only needs to perform the operation through the setting tool when performing the tire tire pressure sensor ID and the position corresponding setting, and the tire is not required to be deflated and inflated, and the tire tire pressure is being performed. When the sensor ID and the position are set correspondingly, the temperature value or the pressure value to be alerted may be set together, which is faster and easier than the current operation mode.
