[0015] Example 1 Figure 1 This is a flowchart of a vehicle zero-position calibration and fault handling method according to Embodiment 1 of this application. This embodiment is applicable to the zero-position calibration, fault clearing, and detection of a one-button steering system. It can be performed by a vehicle zero-position calibration and fault handling device, which can be implemented in hardware and / or software. This device can be configured in a computer device, such as the main control board of a one-button zero-position calibration device. Figure 1 As shown, the method includes: S110. Select the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board; the instruction interaction logic includes at least one of the following instructions: zero position clear instruction, zero position calibration instruction, zero position storage instruction, fault code clear instruction, or fault code detection instruction, as well as the result parsing strategy associated with the instruction and the execution order between the instructions.

[0016] The main control board controls the entire operation of the one-button zero-position calibration processing device. It can pre-configure and store zero-position clearing commands, zero-position calibration commands, zero-position storage commands, fault code clearing commands, and fault code detection commands required by the vehicle's electric power steering system, as well as the result parsing strategy and execution order of the commands. The zero-position clearing command clears the currently stored zero-position data in the ECU (Electronic Control Unit) of the EPS (Electric Power Steering). To ensure that new zero-position calibration is not interfered with by old data, clearing old data before each calibration avoids calibration failures caused by incorrect or inaccurate old data. The zero-position calibration command initiates the zero-position calibration process, causing the EPS system to recalculate and store new zero-position data based on the current steering wheel position (mechanical center position), ensuring the accuracy of the steering system's zero-position data and thus guaranteeing the vehicle's directional stability when driving straight. The zero-position storage command writes the newly calibrated zero-position data to the NVM (Non-Volatile Memory), ensuring data integrity after power failure. Only by storing the data in the NVM can the vehicle retain the correct zero-position data upon restart. The fault code clearing command clears stored fault codes in the EPS system, preparing the system for normal operation. After troubleshooting, fault codes must be cleared to prevent false alarms or functional limitations caused by old fault codes. The fault code detection command detects new fault codes in the EPS system, ensuring the system is functioning correctly after calibration. Detecting fault codes after each operation allows for timely detection and handling of new problems, ensuring reliability and safety. The result parsing strategy refers to the main control board taking appropriate actions based on the received command execution results, ensuring the accuracy and reliability of the entire calibration and fault handling process. Different commands are associated with different result parsing strategies. The command interaction logic can be pre-configured.

[0017] Optionally, the execution order of the instructions is as follows: zero-position clear instruction, zero-position calibration instruction, zero-position storage instruction, fault code clear instruction, and fault code detection instruction are executed sequentially.

[0018] Specifically, in vehicle zero-point calibration and fault handling scenarios, the zero-point clear command, zero-point calibration command, zero-point storage command, fault code clear command, and fault code detection command each play a different role. These commands are executed sequentially to ensure the accuracy and reliability of the entire process, avoid data conflicts and errors, and improve stability and safety. Before performing a new zero-point calibration, the old data must be cleared; otherwise, the old data will interfere with the storage of the new data. After the zero-point calibration is completed, the new data must be stored in the NVM to ensure data persistence. Then, fault code clearing and detection are performed, effectively reducing the occurrence of errors and abnormal situations.

[0019] Optionally, the one-button zero-position calibration processing device further includes a trigger module, which includes function buttons. The trigger module and the main control board are communicatively connected. Accordingly, before selecting the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board, the device further includes: in response to the operator's triggering operation on the function buttons, selecting the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board.

[0020] The one-button zero-position calibration processing device also includes a trigger module. The trigger module is equipped with function buttons to realize a complete operation process, including one-button triggering of the main control board to perform zero-position clearing, zero-position calibration, zero-position calibration result judgment, ECU restart, fault code clearing, fault status reading, and information output.

[0021] Optionally, the one-button zero-position calibration processing device further includes a power module and an indicator light module. The indicator light module includes a first indicator light. The power module, the indicator light module, and the main control board are communicatively connected. Accordingly, before selecting the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board, the device further includes: after the power is turned on by the power module, if the first indicator light flashes green, then the current instruction and the current result parsing strategy associated with the current instruction are selected from the instruction interaction logic preset on the main control board; if the first indicator light flashes red, then an abnormal information is prompted to the operator.

[0022] The power module provides a stable power supply for the one-button zero-position calibration processing device. It supports external power supply and can also control the power supply of the vehicle's electric power steering system via relays controlled by the main control board. The indicator light module uses different colored and status indicator lights to provide feedback on the device's operating status to the operator. The indicator light module includes a first indicator light to indicate the operating status of the one-button zero-position calibration processing device. Specifically, if the first indicator light flashes green, it indicates that the device is powered on and can work normally, selecting the current command and its associated result parsing strategy from the pre-set command interaction logic on the main control board; if the first indicator light flashes red, it indicates a device malfunction, prompting the operator with an error message.

[0023] S120. The current command is sent to the electronic control unit in the vehicle's electric power steering system through the communication module in the main control board, so that the electronic control unit executes the operation corresponding to the current command and feeds back the result of the current command to the main control board.

[0024] The main control board contains a communication module that establishes a communication connection with the steering system ECU via a CAN bus. This module is used to send zero-position clear commands, zero-position calibration commands, zero-position storage commands, fault code clear commands, or fault code detection commands, and to receive data from the ECU.

[0025] S130. The current instruction result is parsed using the current result parsing strategy. If the current instruction result is successful, the execution instruction selection operation is returned according to the execution order of the instructions.

[0026] The current result parsing strategy refers to the main control board taking corresponding processing measures based on the execution result of the received current instruction, ensuring the accuracy and reliability of the entire calibration and fault handling process. Different instructions are associated with different result parsing strategies. The current result parsing strategy can include success parsing strategies and failure parsing strategies. The success parsing strategy means that when an instruction is executed successfully, the main control board will take the corresponding next step according to the instruction type. The failure parsing strategy means that when an instruction is executed unsuccessfully, the main control board will take corresponding processing measures according to the reason for the failure, such as prompting the operator with abnormal information so that the operator can check for abnormalities. For example, when the zero-position clearing instruction fails to execute, abnormal information such as communication timeout and ECU non-response can be prompted, and the attempt will be retried. If the attempt fails after 3 retries, an alarm will be issued and subsequent operations will be stopped, prompting the operator to check the hardware connection. When the zero-position calibration instruction fails to execute, abnormal information such as the steering wheel not being in the mechanical neutral position and sensor failure can be prompted, and the attempt will be retried. If the attempt fails after 3 retries, an alarm will be issued and subsequent operations will be stopped, prompting the operator to check the steering wheel position and sensors.

[0027] Optionally, the one-button zero-position calibration processing device further includes a buzzer module and an indicator light module. The indicator light module includes a second indicator light. The buzzer module and the main control board are connected in communication. The device also includes: if the current instruction result is a failure, returning to execute the current instruction operation through the communication module in the main control board to send the current instruction operation to the electronic control unit in the vehicle's electric power steering system; if the number of retries for the current instruction and the result of the current instruction meet the abnormal handling conditions, instructing the second indicator light to flash red and the buzzer module to issue an alarm.

[0028] The exception handling condition is that the number of retries for the current command is greater than or equal to the preset number of retries, and the result of the current command is still a failure. For example, the preset number of retries can be 3, but this application does not limit the specific number of retries and can be adjusted adaptively according to actual conditions. When the number of retries for the current command is greater than or equal to the preset number of retries, and the result of the current command is still a failure, the second indicator light flashes red and the buzzer module issues an alarm. The buzzer module can provide audible feedback to the operator regarding the device's operating status, such as issuing a prompt tone to indicate an operational error. The indicator light module includes a second indicator light, used to indicate the execution result through color and status. For example, when the second indicator light is solid yellow, it indicates calibration is in progress; when the second indicator light is flashing yellow, it indicates a calibration failure, and the EPS response information cannot be received correctly, requiring investigation of the connection link and EPS power supply status; when the second indicator light is solid green, it indicates successful calibration; when the second indicator light is flashing red, it indicates calibration failure. The main control board controls the lighting and extinguishing of the colors to provide intuitive feedback on the operation result.

[0029] This application selects the current command and its associated result parsing strategy from the command interaction logic preset on the main control board. The command interaction logic includes at least one of the following commands: zero-position clearing command, zero-position calibration command, zero-position storage command, fault code clearing command, or fault code detection command, as well as the associated result parsing strategy and the execution order of the commands. The current command is sent to the electronic control unit (ECU) in the vehicle's electric power steering system via the communication module on the main control board, causing the ECU to execute the operation corresponding to the current command and return the result to the main control board. The current result parsing strategy is used to parse the current command result; if the result is successful, the execution order of the commands is followed, returning to the command selection operation. This solution achieves one-click automated zero-position clearing and calibration, power-down storage detection, fault code clearing and confirmation, etc., simplifying operation, lowering the operational threshold, and eliminating professional processes such as software operation, information interpretation, and power-on / off procedures. The result is directly presented through indicator light colors and status accompanied by a buzzer module alarm, conforming to common sense and avoiding misjudgments due to complex environments or parsing errors, thus improving the efficiency and accuracy of vehicle zero-position calibration and fault handling.

[0030] Example 2 Figure 2 This is a flowchart of a vehicle zero-position calibration and fault handling method according to Embodiment 2 of this application. Based on the technical solutions of the above embodiments, this embodiment adds the following: "If the current instruction is the zero-position storage instruction, correspondingly, after the current instruction result is successful, it further includes: controlling the vehicle relay to disconnect the power supply of the vehicle's electric power steering system, and after a preset time threshold, controlling the vehicle relay to connect the power supply of the vehicle's electric power steering system; querying the zero-position calibration status stored in the electronic control unit through the communication module in the main control board, and if the zero-position calibration status is successful, then returning to the execution instruction selection operation according to the execution order of the instructions." It should be noted that for parts not detailed in this embodiment, please refer to the relevant descriptions in other embodiments. For example... Figure 2 As shown, the method includes: S210. Select the zero-position storage instruction and the current result parsing strategy associated with the zero-position storage instruction from the instruction interaction logic preset on the main control board.

[0031] The zero-position storage command is used to write the newly calibrated zero-position data into the NVM, ensuring that the data is not lost after power failure. Only by storing the data in the NVM can the correct zero-position data be guaranteed after the vehicle restarts. The current result parsing strategy associated with the zero-position storage command may include, in the event of execution failure, prompting the NVM with abnormal information such as NVM write failure and communication error, and retrying. If it still fails after 3 retries, an alarm will be issued and subsequent operations will be stopped, prompting the operator to check the ECU and NVM; it may also include, in the event of successful execution, sending a fault code clearing command to clear fault codes and perform detection.

[0032] S220. The zero-position storage command is sent to the electronic control unit in the vehicle's electric power steering system through the communication module in the main control board, so that the electronic control unit executes the operation corresponding to the zero-position storage command and feeds back the current command result to the main control board.

[0033] The electric power steering system is the core assembly of the vehicle's steering system, comprising components such as a motor, reduction gear, and ECU, providing steering assistance to the driver. The current command result is a status feedback, typically a status code, returned to the main control board via the CAN bus after the ECU has executed the command, indicating whether the operation was successful. If the main control board does not receive a response from the electronic control unit within a preset time threshold, it will resend the zero-position storage command. If no response is received after repeating this a preset number of times, the second indicator light will flash yellow, accompanied by an alarm from the buzzer module.

[0034] S230. The current instruction result is parsed using the current result parsing strategy. If the current instruction result is successful, the vehicle relay is controlled to disconnect the power supply of the vehicle's electric power steering system, and after a preset time threshold, the vehicle relay is controlled to connect the power supply of the vehicle's electric power steering system.

[0035] Specifically, after the main control board receives the zero-position calibration result from the electronic control unit and responds positively, it can control the vehicle relay to disconnect the power supply to the KL15 of the vehicle's electric power steering system, wait for 2 seconds, and then reconnect the power supply to the KL15 of the vehicle's electric power steering system. By powering off and restarting, it verifies whether the EPS system has correctly stored the zero-position calibration result in the non-volatile memory area and whether it has taken effect.

[0036] S240. Query the zero-position calibration status stored in the electronic control unit through the communication module in the main control board. If the zero-position calibration status is successful, return to the execution instruction selection operation according to the execution order of the instructions.

[0037] The zero-point calibration status is a flag bit stored in the ECU's NVM, used to indicate whether the zero-point calibration was successfully completed. The zero-point calibration status can include success or failure.

[0038] In one alternative implementation, the steering system assembly is adjusted to the mechanical center position, and the one-button zero-position calibration processing device box is connected to the CAN bus interface of the steering system ECU through the diagnostic interface (equipped with a 120-ohm terminating resistor). When the power is turned on, the indicator light of the calibration box flashes green, indicating that the calibration box can work normally. Pressing the function button of the button module triggers the main control board to start the operation process.

[0039] The main control board sends a zero-point calibration clear command to the ECU (EPS) via the CAN communication module to avoid the fault that the zero point has been calibrated but cannot be recalibrated (if no response is received from the EPS after 2 seconds, the command is sent again; if no response is received after 3 repetitions, the indicator light flashes yellow and a buzzer sounds for 5 seconds); after receiving the command, the EPS performs the zero-point clearing operation and sends a positive response (including zero-point clearing success / failure data) back to the device box after completion; after receiving the zero-point clearing operation feedback data sent by the EPS, the main control board parses the zero-point clearing operation result. If the zero-point clearing is successful, the next step is executed; otherwise, the zero-point clearing operation is executed again (if the failure is repeated 3 times, the indicator light flashes red and a buzzer sounds for 5 seconds).

[0040] The main control board sends a zero-position calibration command to the ECU (EPS) via the CAN communication module (if no response is received from the EPS within 2 seconds, the command is sent again; if no response is received after 3 repetitions, the indicator light flashes yellow and a buzzer sounds for 5 seconds); after receiving the command, the EPS performs the zero-position calibration operation and sends a positive response back to the device box (including zero-position clearing success / failure data); after receiving the zero-position calibration operation feedback data from the EPS, the main control board parses the zero-position calibration operation result. If the zero-position calibration is successful, it continues to the next step; otherwise, it continues to perform the zero-position calibration operation (if the failure occurs 3 times, the indicator light flashes red and a buzzer sounds for 5 seconds).

[0041] The main control board sends a zero-position storage command to the ECU (EPS) via the CAN communication module (if no response is received from the EPS after 2 seconds, it will send the command again; if no response is received after 3 repetitions, the indicator light will flash yellow and a buzzer will sound for 5 seconds); after receiving the zero-position storage command, the EPS stores the calibration result, updates the internal calibration status, and sends a positive response back to the device box; after receiving the positive response from the EPS to store the calibration result, the main control board controls the relay to disconnect the power to KL15 of the EPS, waits 2 seconds, and then reconnects the power to KL15 to check the EPS calibration status. If the storage is successful, it continues to the next step; otherwise, it re-executes the zero-position calibration and stores the result.

[0042] The main control board sends a fault code clearing command to the ECU (EPS) via the CAN communication module (if no response is received from the EPS within 2 seconds, it will be sent again; if no response is received after 3 repetitions, the indicator light will flash yellow and a buzzer will sound for 5 seconds); after receiving the fault code clearing command, the EPS clears the fault, updates the internal fault status, and reports the response status (positive response / negative response) to the device box; after receiving the fault code clearing response from the EPS, if the main control board is positive, it will continue to the next step; if it is negative, it will send the fault code clearing command again.

[0043] The main control board sends a fault code detection command to the ECU (EPS) via the CAN communication module. (If no response is received from the EPS within 2 seconds, the command is sent again; if no response is received after three repetitions, the indicator light flashes yellow and a buzzer sounds for 5 seconds.) Upon receiving the fault code detection command, the EPS executes relevant operations and reports the response status (positive response / negative response; a positive response includes result data, a negative response includes a failure code). After receiving the fault code response from the EPS, the main control board analyzes the fault status if it is a positive response; otherwise, it resends the fault code detection command. If the positive response indicates no fault, the indicator light turns solid green, and automatic zero-point calibration, restart storage detection, fault clearing, and detection are completed. If the positive response carries fault code information, the indicator light flashes red and a buzzer sounds for 5 seconds, indicating calibration failure.

[0044] In this embodiment, the main control board communicates with the ECU via the CAN communication module to exchange commands for zero-position clearing and calibration, power-on and power-off, and fault code clearing and detection. Based on the execution results, the main control board controls the indicator lights and buzzer. For each command interaction, the main control board must determine whether the current operation was successful based on the information from the ECU. If successful, it automatically executes the next step; otherwise, it repeats the previous operation request until the ECU reports success. All processes are completed automatically. After all operations are completed successfully, the indicator light remains solid green, and the buzzer does not respond. If the indicator light flashes yellow and the buzzer sounds, the operation is considered abnormal, and the wiring harness and other operating environment components need to be checked. If the indicator light flashes red and the buzzer sounds, the ECU is considered abnormal, and the ECU itself needs to be checked. Operators can confirm the calibration results and fault conditions through the indicator light status and alarm sounds. The judgment result, combined with the indicator light and alarm sounds, is determined after a single button press, avoiding misjudgment.

[0045] This application embodiment selects the current instruction and its associated result parsing strategy from the instruction interaction logic preset on the main control board. The instruction interaction logic includes at least one of the following: zero-position clearing instruction, zero-position calibration instruction, zero-position storage instruction, fault code clearing instruction, or fault code detection instruction, as well as the associated result parsing strategy and the execution order of the instructions. The current instruction is sent to the electronic control unit (ECU) in the vehicle's electric power steering system via the communication module in the main control board, causing the ECU to execute the operation corresponding to the current instruction and return the result to the main control board. The current result parsing strategy is used to parse the current instruction result; if the result is successful, the execution order of the instructions is followed, returning to the selected instruction selection operation. This solution achieves one-click automated zero-position clearing and calibration, power-down storage detection, fault code clearing and confirmation, etc., simplifying operation, lowering the operational threshold, eliminating professional processes such as software operation, information interpretation, and power-on / off procedures, and improving the efficiency of vehicle zero-position calibration and fault handling.

[0046] Example 3 Figure 3 This is a structural schematic diagram of a vehicle zero-position calibration and fault handling device according to Embodiment 3 of this application. This embodiment is applicable to the zero-position calibration, fault clearing, and detection of a one-button steering system. The vehicle zero-position calibration and fault handling device can be implemented in hardware and / or software, and can be configured in a computer device, such as the main control board of a one-button zero-position calibration processing device. Figure 3 As shown, the device includes: The instruction and strategy selection module 310 is used to select the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board; the instruction interaction logic includes at least one of the following instructions: zero position clearing instruction, zero position calibration instruction, zero position storage instruction, fault code clearing instruction, or fault code detection instruction, as well as the execution order between the result parsing strategy associated with the instruction and the instruction. The instruction execution module 320 is used to send the current instruction to the electronic control unit in the vehicle's electric power steering system through the communication module in the main control board, so that the electronic control unit executes the operation corresponding to the current instruction and feeds back the result of the current instruction to the main control board; The instruction result parsing module 330 is used to parse the current instruction result using the current result parsing strategy. If the current instruction result is successful, the execution instruction selection operation is returned according to the execution order of the instructions.

If the zero-position calibration status is successful, the module returns to the instruction selection operation according to the execution order of the instructions.

[0049] Optionally, the one-button zero-position calibration processing device further includes a trigger module, which includes function keys. The trigger module and the main control board are communicatively connected. Accordingly, the device further includes a function key trigger module, which is used to select the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board before selecting the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board, in response to the operator's triggering operation on the function key.

[0050] Optionally, the one-button zero-position calibration processing device further includes a power module and an indicator light module. The indicator light module includes a first indicator light. The power module, the indicator light module, and the main control board are communicatively connected. Correspondingly, the device further includes an abnormal information prompting module, which is used to, after powering on via the power module, before selecting the current instruction and the current result parsing strategy associated with the current instruction from the instruction interaction logic preset on the main control board, if the first indicator light flashes green, then the current instruction and the current result parsing strategy associated with the current instruction are selected from the instruction interaction logic preset on the main control board; if the first indicator light flashes red, then an abnormal information is prompted to the operator.
