Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a method, device and storage medium for positioning vehicle tires. Background Technology

[0002] During daily vehicle use, drive wheel tires wear out faster than non-drive tires because they bear more stress and perform heavier tasks. To ensure even wear and extend tire life, tires are usually rotated after a certain mileage. Additionally, during rainy or snowy seasons when roads are slippery, snow tires are often replaced to ensure driving safety.

[0003] When changing tires, because the tire pressure sensor is located inside the tire, whether it's a routine tire rotation or seasonal tire replacement, any change in the tire's position within the vehicle will cause the tire pressure monitoring data displayed on the instrument panel to be inconsistent with the actual position. This can affect the driver's judgment and pose a potential danger to driving. Therefore, ensuring that the tire pressure monitoring data is correctly positioned on the instrument panel when changing tire positions or during tire replacement is a problem that needs to be solved. Summary of the Invention

[0008] In response to the detection result that the driving speed has reached the target condition, the tire pressure radio frequency signal of each tire is collected.

[0012] A second tire positioning result is generated based on the driving operation and the rotational speed of each tire;

[0013] The final tire positioning result is generated by combining the TPMS ID of each tire, the first tire positioning result, and the second tire positioning result.

[0015] The first acquisition module is used to acquire the vehicle's driving speed in response to recognizing that the vehicle has ended its sleep mode and is powered on.

[0016] The second acquisition module is used to acquire the detection result of the target condition based on the driving speed, and the detection result of the target condition is used to indicate whether the driving speed has reached the target condition;

[0021] The second generation module is used to generate a second tire positioning result based on the driving operation and the rotational speed of each tire;

[0022] The third generation module is used to combine the TPMS ID of each tire, the first tire positioning result, and the second tire positioning result to generate the final tire positioning result.

[0030] Figure 3 This is a schematic diagram of the structure of a vehicle tire positioning device provided in an embodiment of this application. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] This application provides a method for positioning vehicle tires. Please refer to... Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. The implementation environment may include: BDCM (Body Domain Control Module) 11, VCU (Vehicle Control Unit) 12, ESP (Electronic Stability Program) 13, tire pressure sensor 14, wheel speed sensor 15, ECU 16, and a display screen 17 on the center console.

[0033] Optionally, VCU12 is used to acquire the vehicle's sleep state and power-on / off status and upload them to BDCM11; ESP13 acquires the vehicle's driving speed and uploads it to BDCM11. Tire pressure sensors 14 are installed on each tire and integrate accelerometers to collect tire pressure radio frequency signals from each tire and upload them to BDCM11. The tire pressure radio frequency signals include customerbyte, TPMS ID, and acceleration.

[0034] For example, wheel speed sensors 15 are mounted on each tire to collect tire rotation speed. After detecting that the driving speed has reached the target condition, they send wheel speed pulse signals to the external BDCM 11. The ECU 16 acquires vehicle driving operations and uploads them to the BDCM 11. Vehicle driving operations include steering and acceleration. The display screen 17 on the center console displays the parameters of each tire after adjustment based on the final tire alignment results. It also displays a prompt indicating that the first tire alignment result and the second tire alignment result are inconsistent and require manual verification of the wheel alignment.

[0035] Among them, BDCM11, VCU12, ESP13, tire pressure sensor 14, wheel speed sensor 15, ECU16 and the display screen 17 of the center console establish communication connection through wired or wireless network.

[0036] Based on the above Figure 1 The implementation environment shown in this application embodiment provides a method for positioning vehicle tires. Figure 2 As shown, taking the application of this method to BDCM as an example, the method includes steps 201-208.

[0037] In step 201, in response to the recognition that the vehicle has ended its sleep mode and is powered on, the BDCM acquires the vehicle's driving speed.

[0038] In one possible implementation, the BDCM can obtain the vehicle's sleep state and power-on / off state through the VCU, where the vehicle's power-on / off state includes either a power-on state or a power-off state. If it is detected that the vehicle has ended its sleep state and is in a power-on state, the BDCM obtains the vehicle's driving speed, including obtaining the vehicle's driving speed from the ESP through the CGW (Cloud Gateway).

[0039] In step 202, the BDCM obtains the detection result of the target condition based on the driving speed. The detection result of the target condition is used to indicate whether the driving speed has reached the target condition.

[0040] Optionally, after acquiring the vehicle's speed, the BDCM obtains a detection result of the target condition based on the speed, wherein the detection result of the target condition is used to indicate whether the speed has reached the target condition. In one possible implementation, the BDCM obtains the detection result of the target condition based on the speed by: in response to the speed accumulating a certain number of times to reach a speed threshold and remaining there for a certain period of time, obtaining a detection result indicating that the speed has reached the target condition.

[0041] For example, after acquiring the vehicle's speed, the BDCM compares the speed with a speed threshold. If the speed reaches the speed threshold and remains there for a certain period of time, and accumulates a certain number of times, the BDCM obtains a detection result indicating that the speed has met the target condition. If the speed does not reach the speed threshold, reaches the speed threshold but does not remain there for a certain period of time, or reaches the speed threshold and remains there for a certain period of time but does not accumulate a certain number of times, the BDCM obtains a detection result indicating that the speed has not met the target condition. Optionally, the certain number of times, the speed threshold, and the period of time can be set based on experience; for example, the certain number of times can be set to 6 times, the period of time can be set to 16 seconds, and the speed threshold can be set to 25 kilometers per hour.

[0042] In step 203, in response to the detection result that the driving speed has reached the target condition, the BDCM collects the tire pressure radio frequency signal of each tire. The tire pressure radio frequency signal includes customer byte, TPMS ID and acceleration, and customer byte, TPMS ID and acceleration correspond one-to-one.

[0043] For example, after obtaining the detection result of the target condition, in response to obtaining the detection result that the driving speed has reached the target condition, the BDCM collects the tire pressure radio frequency signal of each tire, wherein the tire pressure radio frequency signal includes customerbyte, TPMS ID and acceleration, and customerbyte, TPMS ID and acceleration correspond one-to-one.

[0044] In one possible implementation, if the detection result indicates that the driving speed has reached the target condition, the BDCM collects the tire pressure radio frequency signal of each tire, including: the BDCM receives the tire pressure radio frequency signal of each tire sent by the tire pressure sensor through the built-in radio frequency receiver chip, wherein at least 5 data packets of tire pressure radio frequency signal are collected for each tire.

[0045] Optionally, the tire pressure sensors are mounted on each tire and integrate accelerometers. When the vehicle reaches a target speed, the tire pressure sensors transmit a tire pressure radio frequency signal. This signal includes a customer byte, a TPMS ID, and an acceleration value, with each byte corresponding to a different value. The acceleration value includes lateral and longitudinal acceleration. For example, the TPMS ID and customer byte are pre-programmed into the tire pressure sensor's firmware or hardware by the supplier. The TPMS ID distinguishes between different tire pressure sensors, and the customer byte distinguishes between different tire pressure sensor suppliers.

[0046] In step 204, BDCM obtains the verification results of customer byte and TPMS ID. The verification results of customer byte and TPMS ID are used to indicate whether the verification of customer byte and TPMS ID has passed.

[0047] For example, after obtaining the customer byte and TPMS ID of each tire, the BDCM obtains the verification result of the customer byte and TPMS ID, wherein the verification result of the customer byte and TPMS ID is used to indicate whether the verification of the customer byte and TPMS ID has passed. Optionally, the BDCM obtains the verification result of the customer byte and TPMS ID by: in response to the number of TPMS ID categories being equal to the number of tires, and the customer byte of each tire being consistent, obtaining a detection result indicating that the verification of the customer byte and TPMS ID has passed.

[0048] In one possible implementation, the number of TPMS IDs in the acquired tire pressure radio frequency signal is counted, and compared with the customer byte of each tire. If the number of TPMS ID categories equals the number of tires, and the customer bytes of all tires are consistent, the BDCM obtains a detection result indicating that the verification of the customer byte and TPMS ID has passed. If the number of TPMS ID categories does not equal the number of tires, or at least two tires have inconsistent customer bytes, the BDCM obtains a detection result indicating that the verification of the customer byte and TPMS ID has failed. Optionally, the number of tires can be obtained in advance.

[0049] In step 205, in response to the detection result that the customer byte and TPMS ID have passed verification, the BDCM collects the rotational speed of each tire and the driving operation of the vehicle.

[0050] Optionally, after obtaining the verification results of the customer byte and TPMS ID, if the verification of the customer byte and TPMS ID is successful, the BDCM collects the rotational speed of each tire and the vehicle's driving operations, including: the BDCM receiving wheel speed pulse signals from each tire sent by the wheel speed sensors, wherein the wheel speed pulse signals contain the rotational speed of the tire where the wheel speed sensor is located; and obtaining the vehicle's driving operations through the ECU, including steering or acceleration. For example, the wheel speed sensors are installed on each tire, and after a detection result indicating that the driving speed has reached the target condition, the wheel speed sensors are triggered to send out wheel speed pulse signals.

[0051] In step 206, the BDCM generates a first tire alignment result based on the driving operation and the acceleration of each tire.

[0052] For example, after obtaining the driving operation and the acceleration of each tire, the BDCM generates a first tire positioning result based on the driving operation and the acceleration of each tire, including: in response to the driving operation being a steering driving, determining that the tire on the side with the smaller lateral acceleration is located on the side of the steering direction; in response to the driving operation being an acceleration driving, determining that the tire on the side with the larger longitudinal acceleration is located on the side of the drive wheel.

[0053] In one possible implementation, if the driving operation is a turning operation, the tire on the side with the smaller lateral acceleration is located on the side of the turning direction. For example, if the driving operation is a left turn, the tire on the side with the smaller lateral acceleration is located on the left side of the vehicle, and the tire on the side with the larger lateral acceleration is located on the right side of the vehicle; if the driving operation is a right turn, the tire on the side with the smaller lateral acceleration is located on the right side of the vehicle, and the tire on the side with the larger lateral acceleration is located on the left side of the vehicle.

[0054] Optionally, if the driving operation is acceleration and the vehicle's drive wheels are front wheels, the tire on the side with greater longitudinal acceleration is located at the front of the vehicle, and the tire on the side with less longitudinal acceleration is located at the rear of the vehicle; if the driving operation is acceleration and the vehicle's drive wheels are rear wheels, the tire on the side with less longitudinal acceleration is located at the front of the vehicle, and the tire on the side with greater longitudinal acceleration is located at the rear of the vehicle.

[0055] In step 207, the BDCM generates a second tire alignment result based on the driving operation and the rotational speed of each tire.

[0056] For example, after obtaining the driving operation and the rotational speed of each tire, a second tire positioning result is generated based on the driving operation and the rotational speed of each tire, including: in response to the driving operation being a steering operation, determining that the tire on the side with the lower rotational speed is located on the side of the steering direction; in response to the driving operation being an acceleration operation, determining that the tire on the side with the higher rotational speed and the faster speed increase is located on the side of the drive wheel.

[0057] In one possible implementation, if the driving operation is a turning operation, the tire on the side with the lower rotational speed is located on the side of the turning direction. For example, if the driving operation is a left turn, the tire on the side with the lower rotational speed is located on the left side of the vehicle, and the tire on the side with the higher rotational speed is located on the right side of the vehicle; if the driving operation is a right turn, the tire on the side with the lower rotational speed is located on the right side of the vehicle, and the tire on the side with the higher rotational speed is located on the left side of the vehicle.

[0058] Optionally, if the driving operation is acceleration and the vehicle's drive wheels are front wheels, the tire on the side with higher rotational speed and faster speed increase is located at the front of the vehicle, and the tire on the side with lower rotational speed and slower speed increase is located at the rear of the vehicle; if the driving operation is acceleration and the vehicle's drive wheels are rear wheels, the tire on the side with higher rotational speed and faster speed increase is located at the rear of the vehicle, and the tire on the side with lower rotational speed and slower speed increase is located at the front of the vehicle. For example, the detection result of whether the drive wheels are front or rear wheels can be obtained in advance.

[0059] In step 208, the BDCM combines the TPMS ID of each tire, the first tire alignment result, and the second tire alignment result to generate the final tire alignment result.

[0060] For example, after obtaining the first tire positioning result and the second tire positioning result, the BDCM combines the TPMS ID of each tire, the first tire positioning result and the second tire positioning result to generate the final tire positioning result, including: in response to the consistency between the first tire positioning result and the second tire positioning result, determining the TPMS ID of each tire and the first tire positioning result as the detection result of the target condition.

[0061] In one possible implementation, the first tire alignment result and the second tire alignment result are compared. If the first tire alignment result and the second tire alignment result are consistent, the BDCM determines the TPMS ID of each tire and the first tire alignment result as the detection result of the target condition. That is, the parameters displayed on the center console screen are adjusted according to the correspondence between the first tire alignment result and the TPMS ID. If the first tire alignment result and the second tire alignment result are inconsistent, the parameters of each tire on the display screen are not adjusted, and a message is displayed on the screen indicating that the first tire alignment result and the second tire alignment result are inconsistent, requiring manual verification of the wheel alignment.

[0062] This embodiment of the application acquires the vehicle's speed after powering on from sleep mode and determines whether the speed meets the target conditions. If the speed meets the target conditions, the vehicle collects the tire pressure radio frequency signals of each tire, including a customer byte, TPMS ID, and acceleration. The system then checks whether the verification of the customer byte and TPMS ID passes. If the verification of the customer byte and TPMS ID passes, the system collects the rotational speed of each tire and the vehicle's driving operation. A first tire positioning result is generated based on the driving operation and the acceleration of each tire, and a second tire positioning result is generated based on the driving operation and the rotational speed of each tire. Finally, the system combines the TPMS ID of each tire, the first tire positioning result, and the second tire positioning result to generate the final tire positioning result. This ensures that when changing tire positions or replacing tires, the position of the tire monitoring data on the instrument panel is changed accordingly, guaranteeing that the tire pressure information displayed on the vehicle's instrument panel is consistent with the actual tire pressure.

[0063] See Figure 3 This application provides a vehicle tire positioning device, which includes:

[0064] The first acquisition module 301 is used to acquire the vehicle's driving speed in response to recognizing that the vehicle has ended its sleep mode and is powered on.

[0065] The second acquisition module 302 is used to acquire the detection result of the target condition based on the driving speed. The detection result of the target condition is used to indicate whether the driving speed has reached the target condition.

[0066] The first acquisition module 303 is used to acquire the tire pressure radio frequency signal of each tire in response to the detection result that the driving speed has reached the target condition. The tire pressure radio frequency signal includes a customer byte, a tire pressure monitoring system identifier (TPMS ID), and acceleration. The customer byte, TPMS ID, and acceleration are in one-to-one correspondence.

[0067] The third acquisition module 304 is used to acquire the verification results of customer byte and TPMS ID. The verification results of customer byte and TPMS ID are used to indicate whether the verification of customer byte and TPMS ID has passed.

[0068] The second acquisition module 305 is used to acquire the rotational speed of each tire and the driving operation of the vehicle in response to the detection result that the customer byte and TPMS ID have passed the verification.

[0069] The first generation module 306 is used to generate the first tire positioning result based on the driving operation and the acceleration of each tire;

[0070] The second generation module 307 is used to generate a second tire positioning result based on the driving operation and the rotational speed of each tire;

[0071] The third generation module 308 is used to combine the TPMSID of each tire, the first tire positioning result, and the second tire positioning result to generate the final tire positioning result.

[0072] In one possible implementation, the second acquisition module 302 is used to acquire the detection result that the driving speed has reached the target condition in response to the driving speed accumulating a certain number of times to reach the speed threshold and continuing for a certain period of time.

[0073] In one possible implementation, the driving operation includes steering and acceleration, and the acceleration includes lateral acceleration and longitudinal acceleration. The first generation module 306 is used to determine, in response to the driving operation being steering, that the tire on the side with smaller lateral acceleration is located on the side of the steering direction; and in response to the driving operation being acceleration, to determine that the tire on the side with larger longitudinal acceleration is located on the side of the drive wheel.

[0074] In one possible implementation, the second generation module 307 is used to determine, in response to a driving operation of turning, that the tire on the side with the lower rotational speed is located on the side of the turning direction; and in response to a driving operation of accelerating, to determine that the tire on the side with the higher rotational speed and the faster speed increase is located on the side of the drive wheel.

[0075] In one possible implementation, the third generation module 308 is used to determine the TPMS ID of each tire and the first tire positioning result as the detection result of the target condition in response to the consistency between the first tire positioning result and the second tire positioning result.

[0076] In one possible implementation, the third acquisition module 304 is used to obtain a detection result indicating that the verification of the customer byte and TPMS ID has passed, in response to the fact that the number of TPMS ID categories is equal to the number of tires and the customer byte of each tire is consistent.

[0077] This device acquires the vehicle's speed after powering on from sleep mode and determines whether the speed meets the target conditions. If the speed meets the target conditions, it collects the tire pressure radio frequency (RF) signals of each tire, including customer byte, TPMS ID, and acceleration. It then checks whether the customer byte and TPMS ID verification passes. If the customer byte and TPMS ID verification passes, it collects the rotational speed of each tire and the vehicle's driving operation. Based on the driving operation and the acceleration of each tire, it generates a first tire alignment result, and based on the driving operation and the rotational speed of each tire, it generates a second tire alignment result. Finally, it combines the TPMS ID of each tire, the first tire alignment result, and the second tire alignment result to generate the final tire alignment result. This ensures that when changing tire positions or replacing tires, the position of the tire monitoring data on the instrument panel is changed accordingly, guaranteeing that the tire pressure information displayed on the vehicle's instrument panel is consistent with the actual tire pressure.
