- Step 2224 Compare the random identity information with the real identity information of the tire pressure sensor of the tire position to be matched.

- the identity information is updated to the virtual identity information.
- the diagnostic device can send an OBD diagnostic command (OBD learning mode) to the ECU through wired or wireless methods such as Bluetooth and Wi-Fi, or turn on the tire pressure monitoring system by sending a high-frequency signal to the ECU (high-frequency learning mode).

- the diagnostic device sequentially sends the virtual ID of the tire pressure sensor whose tire position is to be reset to the ECU according to the matching sequence and requirements of the ECU, for example, the four front left, front right, rear left, and rear right
- the random ID of the tire position is sent to the ECU in turn, and the ECU updates the identity information of the tire pressure sensor whose tire position is to be reset to a virtual ID after receiving it. If the tire position to be reset is only the right front position, the diagnostic device only needs to send the virtual ID to the ECU when matching the right front position, and the tire pressure sensor IDs of other tire positions remain unchanged.
- the diagnostic device When the diagnostic device sends the above virtual ID to the ECU, it can use high-frequency signals to transmit data, or it can use OBD wired connection or Bluetooth, Wi-Fi and other wireless methods to transmit data through diagnostic commands.
- Step 240 Obtain the real identity information of the tire pressure sensor of the tire position to be matched; the tire position to be matched includes the tire position to be reset.
- the diagnostic device can obtain the real identity information of the tire pressure sensor in the following ways:
- the diagnostic device can send a low frequency or bluetooth activation signal to the tire pressure sensor whose tire position is to be matched, the tire pressure sensor sends its ID to the diagnostic device after receiving the activation signal, and the diagnostic device receives and stores the ID of the tire pressure sensor.
- Manual input method Specifically, it may include: keyboard input, touch screen input, voice input, or scan code input, etc. After the user manually enters the ID of the tire pressure sensor whose tire position is to be matched, the diagnostic device saves it.
- the diagnostic equipment reads the ID of the tire pressure sensor that has been matched and bound by the tire pressure monitoring system through the OBD system. This method is mainly for the situation that the original tire pressure sensor ID does not need to be replaced, and the sequence of tire pressure sensors does not change. For example, the measured tire pressure data of a tire pressure sensor is inaccurate and needs to be reset.
- step 240 may be executed at any position after step 210 and before step 250 . If the diagnostic device has acquired part of the real identity information of the tire pressure sensor to be matched before step 240, for example, in the case of the above-mentioned tire swapping between the front left position and the front right position, the diagnostic device has acquired the tire position to be reset when determining the position of the tire to be reset. If the real ID of the tire pressure sensor at the front left position is matched, then step 240 may only include acquiring the real identity information of the position of the tire to be reset, that is, the real ID of the tire pressure sensor at the front right position.
- step 240 may be performed at any location before step 250 in this embodiment.
- Step 250 Send the real identity information to the tire pressure monitoring system, so that the tire pressure monitoring system updates the identity information of the tire pressure sensor whose tire position is to be matched to the real identity information.
- the learning mode of the tire pressure monitoring system needs to be turned on again before step 250. Specifically, it can be turned on by sending a high-frequency signal to the ECU, or the user can manually operate the tire pressure monitoring system of the vehicle. to start learning mode.
- the diagnostic device sequentially sends the real IDs of the tire pressure sensors of the tire positions to be matched to the ECU according to the matching sequence and requirements of the ECU. For example, the real IDs of the four tire positions of front left, front right, rear left, and rear right are sequentially Send it to the ECU, and the ECU will update the identity information of the tire pressure sensor of the tire position to be matched to the real ID after receiving it. Since the ECU previously stored the virtual ID of the tire pressure sensor of the tire position to be reset, in step 250, the occurrence of repeated problems when writing the real ID can be effectively avoided, and the success rate of tire pressure sensor matching learning can be improved.
- the diagnostic device When the diagnostic device sends the above real ID to the ECU, it can use high-frequency signals to transmit data, or it can use OBD wired connection or Bluetooth, Wi-Fi and other wireless methods to transmit data through diagnostic commands.
- the diagnostic device determines that the tire pressure sensor matching and learning of the tire position to be matched is successful.
- the tire pressure sensor information processing method determines the tire position to be reset for which the tire pressure sensor identity information clearing operation needs to be performed, and the tire pressure sensor of the tire position in the tire pressure monitoring system is determined.
- the original identity information is updated to virtual identity information, and then the real identity information of the tire pressure sensor of the tire position to be matched is written into the tire pressure monitoring system, which can effectively avoid the real identity information and tire pressure of the tire pressure sensor written in the matching learning process.
- the original identity information saved in the monitoring system is repeated, which greatly improves the success rate of tire pressure sensor matching and improves user experience.
