Description

Method of tire sensor ID registration by quick leak

technical field

The invention relates to the technical field of tire sensor ID registration, in particular to a method for tire sensor ID registration through rapid air leakage.

Background technique

The car tire pressure monitoring system (TPMS) is mainly to install a high-precision tire pressure sensor in the car tire to automatically detect the tire pressure in real time when the vehicle is running, and transmit it to the controller in the passenger compartment through radio frequency to prompt The driver's tire pressure is not normal to ensure driving safety system. In order to distinguish each tire, each corresponding tire pressure sensor has its own unique ID number, and the controller uses the ID number to identify which tire of the vehicle the received tire information comes from. To prevent confusion and misjudgment, the ID number of each tire sensor needs to be registered.

At present, in order to register the sensor ID, it is necessary to add a low-frequency communication module to control and trigger the sensor to send the ID, and then perform the sensor ID registration, which requires additional costs.

At present, there are two schemes for adding low-frequency modules: (1) independent external equipment, (2) arranged in the vehicle. If the method (1) is adopted, the user needs to purchase the device separately or go to a 4S shop every time the tire needs to be registered for ID registration, which is inconvenient to use. If method (2) is adopted, a low-frequency module needs to be added corresponding to each tire, which increases the weight of the vehicle and complicates the wiring of the vehicle.

Contents of the invention

In order to solve the above technical problems, the present invention provides a tire sensor ID registration method through rapid air leakage, which can reduce the cost of the vehicle, improve user convenience or reduce the layout space of the vehicle.

The technical solution of the present invention is that the operator performs a rapid air leakage operation on each tire according to the set ID registration sequence, and when it is detected that the tire pressure changes rapidly beyond the set value, the tires will send their corresponding tire sensor ID numbers to The tire pressure monitoring system controller performs storage to realize the ID registration of the tire pressure sensor.

Further, the method includes the following steps:

S1: The operator sends an ID registration start command to the tire pressure monitoring system controller through the display operation unit;

S2: The tire pressure monitoring system controller displays and outputs the set ID registration sequence through the display operation unit;

S3: The operator performs rapid air leakage operations on the vehicle tires in sequence according to the ID registration sequence output by the display operation unit;

S4: When the tire pressure monitoring system sensor detects that the tire pressure changes rapidly and exceeds the set value, it sends the ID number corresponding to the tire to the tire pressure monitoring system controller for storage, and realizes ID registration.

Further, in the above S2, after receiving the ID registration start command, the tire pressure monitoring system controller controls the tire pressure monitoring system sensor to detect the vehicle state, and if the vehicle is in the driving state, feeds back a signal of refusing to enter the ID registration mode to the display operation unit Display output; if the vehicle is in a stationary state, the signal for confirming entering the ID registration mode will be fed back to the display operation unit for display output. After the operator inputs the confirmation signal in the display operation unit, the set ID registration sequence will be displayed and output through the display operation unit. .

Further, in said S4:

If the tire pressure monitoring system controller receives the ID information sent by all tire sensors within the set time, it will store the received ID information according to the set ID registration sequence, and complete the tire sensor ID registration;

If the tire pressure monitoring system controller does not receive the ID information sent by all the tire sensors within the set time, it will feed back a registration failure signal to the display operation unit and exit the ID registration mode.

Further, in said S4: the tire pressure monitoring system sensor monitors the tire pressure through its internal integrated pressure sensor, and when the tire pressure rapidly changes beyond the set value, the tire ID is sent to the tire pressure monitoring system to control the tire pressure through a radio frequency signal device.

Further, the display operation unit is a vehicle dashboard.

Beneficial effects of the present invention: This method does not need to add a low-frequency module in the controller, and does not need to add low-frequency equipment, and the tire sensor ID registration can be started by using the existing components of the vehicle through the air leakage operation of the tire, which is easy to operate and reduces the system cost. Reduce hardware layout and save vehicle layout space.

The sensors 1 of the tire pressure monitoring system are respectively installed on four tires, including a sensor chip 101 , a radio frequency signal transmitting module 102 , a pressure sensor 103 and an acceleration sensor 104 . The sensor chip 101 is used to control other modules of the tire pressure monitoring system sensor 1, the radio frequency signal transmitting module 102 is used to send radio frequency signals to the tire pressure monitoring system controller 2, the pressure sensor 103 is used to monitor the tire pressure, and the acceleration sensor 104 is used to judge The driving status of the vehicle. The tire pressure monitoring system controller 2 includes a controller chip 201 and a radio frequency signal receiving module 202 , the controller chip 201 is used for realizing ID registration, and the radio frequency signal receiving module 202 is used for receiving the ID signal sent by the radio frequency signal transmitting module 102 . The display operation unit 3 is the instrument panel of the vehicle, and is connected with the tire pressure monitoring system controller 2 through the CAN bus.

As shown in Figure 2, the method for tire sensor ID registration of the present invention comprises the following steps:

S1: The instrument panel of the vehicle gives a specified command as the trigger condition for the start of ID registration. When the operator wants to perform ID registration, he operates according to the specified command on the instrument panel. For example, flip the page switch of the instrument according to the specified action, and the operation is completed. After the ID registration is triggered, the dashboard sends an ID registration start command to the tire pressure monitoring system controller 2 through the CAN bus.

S2: After receiving the ID registration start command, the controller chip 201 in the tire pressure monitoring system controller 2 controls the tire pressure monitoring system sensor 1 to detect the driving state of the vehicle. The detection process is realized by the acceleration sensor 104 . If the acceleration sensor 104 detects that the vehicle is in a driving state, the signal is input to the sensor chip 101, and the sensor chip 101 feeds back the signal to the controller chip 201, and the controller chip 201 feeds back a signal of refusing to enter the ID registration mode to the instrument panel display of the vehicle. Output; if the vehicle is in a static state, then the signal is input to the sensor chip 101, and the sensor chip 101 feeds back the signal to the controller chip 201, and the controller chip 201 will confirm that the signal to enter the ID registration mode is fed back to the instrument panel display output of the vehicle. After the operator enters the signal on the dashboard of the vehicle to confirm entering the ID registration mode, the tire pressure monitoring system controller 2 will set the ID registration sequence in the controller chip 201, such as left front wheel-right front wheel-right rear wheel - The left rear wheel displays the output via the instrument panel of the vehicle.

S3: The operator sequentially performs quick air leakage operations on the vehicle tires according to the ID registration sequence displayed on the vehicle dashboard.

S4: The sensor 1 of the tire pressure monitoring system monitors the tire pressure in real time. When the tire pressure changes rapidly and exceeds the set value within the set time a (manually set), the tire ID is sent to the tire pressure monitoring system controller 2 through a radio frequency signal. . If the tire pressure monitoring system controller 2 receives the ID information sent by all tire sensors within the set time b (manually set), the received ID information will be stored according to the set ID registration sequence, and the tire sensor ID will be completed. Registration: If the tire pressure monitoring system controller 2 does not receive the ID information sent by all tire sensors within the set time, it will feed back a registration failure signal to the instrument panel of the vehicle and exit the ID registration mode.
