[0002] With the development of intelligent and electric vehicles, electric seats have gradually become standard equipment in new energy vehicles. Compared with traditional simple electric seat adjustments, today's electric seats integrate advanced intelligent technologies, such as seat massage, heating and ventilation, welcome memory, and zero-gravity seating. Among these, functions related to seat memory require electric seat calibration, such as calibrating the seat's travel in all directions. After calibration, the seat memory functions, i.e., the seat's overall functionality, can be used normally. Electric seat calibration is usually performed on the vehicle production line. Current calibration methods have a low success rate, resulting in electric seats failing to function after the vehicle rolls off the production line, leading to a high failure rate and impacting vehicle production quality.

[0007] In some embodiments, after determining that the first drive data calibration has failed, the calibration method further includes: re-performing the first drive task on the electric seat in response to the first drive data being less than the minimum value of the calibration range; and overwriting the first drive data with standard drive data in response to the first drive data being greater than the maximum value of the calibration range.
[0008] In some embodiments, the calibration method further includes: obtaining the error driving item corresponding to the data that is less than the minimum value of the calibration range during the first driving data calibration process; and determining the second driving task based on the error driving item.
[0009] In some embodiments, before driving the electric seat to perform the first driving task according to the preset driving items in accordance with the first calibration instruction, the calibration method further includes: detecting whether the vehicle where the electric seat is located meets the seat calibration conditions; wherein, the seat calibration conditions include: there is no user on the electric seat, the vehicle doors are closed, the vehicle gear is in the parking gear, and / or the vehicle's power status meets the calibration requirements.
[0010] In some embodiments, before driving the electric seat to perform a second driving task according to at least one of the preset driving items in accordance with the second calibration instruction, the calibration method further includes: in response to the vehicle where the electric seat is located being at a calibration station, obtaining the first seat barcode information of the electric seat; in response to the completion of the vehicle production line operation phase and the vehicle where the electric seat is located being at an off-line station, obtaining the second seat barcode information of the electric seat; matching the first seat barcode information and the second seat barcode information; and, if the matching is successful, confirming that the electric seat has not been replaced during the vehicle production line operation phase.
[0011] To address the aforementioned technical problems, this application adopts the following technical solution: A calibration system is provided, comprising: an intelligent cloud and an in-vehicle terminal connected to the intelligent cloud; the intelligent cloud is used to issue a first calibration command to the in-vehicle terminal in response to the electric seat being located at a calibration station in the vehicle; the in-vehicle terminal is used to drive the electric seat to perform a first driving task according to preset driving items based on the first calibration command, and to acquire first driving data; the intelligent cloud is also used to control the electric seat to enter the vehicle production line operation stage when the first driving data calibration is successful; and in response to the completion of the vehicle production line operation stage and the vehicle containing the electric seat being located at an off-line station, to issue a second calibration command to the in-vehicle terminal; the in-vehicle terminal is also used to drive the electric seat to perform a second driving task according to at least one driving item in the preset driving items based on the second calibration command, and to acquire second driving data; and to match the first driving data with the second driving data, and determine the calibration result of the electric seat based on the matching result.

[0013] The beneficial effects of this application's embodiments are as follows: In the calibration method of this application, the vehicle terminal performs a first calibration and a second calibration on the electric seat at the calibration station and the off-line station, respectively. The off-line station is the last station before the vehicle is ready to leave the production line. There is a long production line operation phase between the calibration station and the off-line station. During the production line operation phase, there are various factors that affect the seat function of the electric seat. For example, the electric seat may be bumped or blocked by debris during the production line operation phase. Therefore, at the off-line station, the electric seat is driven to perform a second driving task to perform a second calibration on the electric seat. The second calibration determines the fault status of the electric seat after the production line operation phase, and further calibration processing is performed on the electric seat based on the fault status. This improves the success rate of electric seat calibration, thereby effectively reducing the failure rate of the electric seat and thus effectively improving the production quality of the vehicle.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise expressly specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.
[0022] This application provides a calibration method for an electric seat. In its embodiments, this calibration method is primarily applied to the field of automated calibration of vehicle electric seats. However, it is also applicable to other corresponding technical fields. This application mainly elaborates on the calibration method in the field of automated calibration of vehicle electric seats. The execution entity of this calibration method is a calibration system. The calibration system includes an intelligent cloud and an in-vehicle terminal connected to the intelligent cloud. The intelligent cloud communicates with the in-vehicle terminal via communication technology and works with the in-vehicle terminal to calibrate the electric seat. The in-vehicle terminal is the vehicle's infotainment system. Compared to traditional simple electric seat adjustments, today's electric seats integrate advanced intelligent technologies such as seat massage, heating and ventilation, welcome memory, and zero-gravity seating. Functions related to seat memory require electric seat calibration, such as calibrating the seat's travel in all directions. After calibration, the seat memory functions, i.e., the seat's overall functionality, can be used normally.
[0023] like Figure 1 As shown, Figure 1 This is a schematic diagram of the method steps of the first embodiment of the calibration method of this application. The calibration method can be found in [reference needed]. Figure 1 The method steps shown are implemented, specifically including steps S100 to S400, as follows:
[0024] Step S100: In response to the vehicle containing the electric seat being located at the calibration station, drive the electric seat to perform the first driving task according to the first calibration instruction and the preset driving items, and obtain the first driving data.
[0025] When the vehicle carrying the electric seat reaches the calibration station, the motion system sends a first calibration command to the on-board terminal. The on-board terminal, based on this command, drives the electric seat to perform a first driving task according to preset driving parameters and acquires the first driving data to initialize and calibrate the electric seat; this is also known as the first calibration. Optionally, the driving parameter corresponding to the first driving task is bidirectional double-stroke stall zero-point detection. In other words, the on-board terminal controls the electric seat's drive motor to perform bidirectional double-stroke stall zero-point detection based on the first calibration command.
[0026] The calibration system includes an intelligent cloud platform and an in-vehicle terminal. Before executing step S100, the calibration system needs to undergo system initialization to improve its stability during the calibration process. See [link to documentation]. Figure 2 As shown, Figure 2 This is a schematic diagram illustrating the method steps for system initialization of the calibration system described in this application. For details on system initialization, please refer to... Figure 2 The method steps shown are implemented, specifically including steps S101 to S104, as follows:
[0027] Step S101: Power on and connect to the smart cloud.
[0028] The intelligent cloud-based power supply and network ensure the normal operation of the vehicle production line.
[0029] Step S102: The vehicle terminal is powered on and connected to the network.
[0030] The vehicle terminal is powered on and connected to the network to enable communication between the vehicle terminal and the intelligent cloud, ensuring that the vehicle terminal can communicate normally with the intelligent cloud.
[0031] Step S103: Obtain the first seat barcode information of the electric seat from the intelligent cloud.
[0032] The intelligent cloud obtains the first seat barcode information of the electric seat that needs to be calibrated. The intelligent cloud can obtain the parameter information of the electric seat through the first seat barcode information, such as standard drive data and other parameter information. After obtaining the parameter information of the electric seat, the intelligent cloud memorizes the parameter information and sends it to the vehicle terminal. The vehicle terminal memorizes the parameter information of the electric seat.
[0033] Step S104: Start the factory mode based on the startup command.
[0034] The vehicle terminal is equipped with a start command. After the intelligent cloud and the vehicle terminal complete steps S101 to S103, the system initialization preparation is complete. After the system initialization preparation is complete, the vehicle terminal also needs to receive the start command and enter the factory mode based on the correct start command in order to cooperate with the intelligent cloud to perform initialization calibration of the electric seat. This can effectively improve the working reliability of the calibration system. Optionally, a command input channel can be set in the vehicle terminal. For example, after the intelligent cloud and the vehicle terminal complete steps S101 to S103, the vehicle's central control screen displays the input start command operation. In response to the user's correct start command input, the vehicle terminal starts the factory mode, and the calibration system completes the system initialization based on this.
[0035] After system initialization is complete (i.e., after the vehicle terminal enters factory mode), the intelligent cloud monitors the vehicle in real time through connected external devices. Upon detecting that the vehicle has entered the calibration station, it sends the first calibration command to the vehicle terminal. The vehicle terminal executes step S100 to initialize and calibrate the electric seat according to the first calibration command. If the vehicle terminal cannot obtain the first calibration command from the intelligent motion system, the calibration station will issue an alarm to indicate the fault, thereby enabling manual handling by the operator, such as manually issuing the first calibration command.
[0036] Optionally, before the vehicle terminal executes step S100 to initialize and calibrate the electric seat according to the first calibration instruction, the vehicle terminal may also detect whether the vehicle where the electric seat is located meets the seat calibration conditions. The seat calibration conditions include: there is no user on the electric seat, the vehicle doors are closed, the vehicle gear is in the parking gear, and / or the vehicle's power status meets the calibration requirements.
[0037] Specifically, after receiving the first calibration command, the vehicle terminal uses occupant detection sensors to check if anyone is inside the vehicle (whether a user or operator is present). When someone is detected in any seat, a vehicle safety alarm is triggered, and the central control screen displays "Seat calibration in progress, please exit the vehicle," reminding the occupants to leave the vehicle. If no one is detected inside the vehicle, the vehicle terminal further checks the vehicle door status, vehicle gear status, and vehicle power status. If the vehicle terminal detects that the vehicle doors are closed, the vehicle is in park, and the vehicle power status meets the calibration requirements, the vehicle terminal determines that the vehicle containing the electric seat meets the seat calibration conditions and performs initial calibration of the electric seat in step S100. For example, after the onboard terminal determines that the vehicle containing the power seat meets the seat calibration conditions, it sends a first calibration command to the power seat's control module. This command causes the control module to simultaneously drive multiple motors of the power seat, enabling each motor to perform a first driving task. This first driving task can be bidirectional, dual-stroke stall learning (or bidirectional, dual-stroke stall zero-point detection). The onboard terminal records the first driving data and uploads it to the intelligent cloud. Based on this, the onboard terminal automatically determines the seat calibration conditions, effectively reducing manual intervention and thus significantly improving the calibration efficiency of the power seat.
[0038] Step S200: When the first drive data calibration is successful, control the electric seat to enter the vehicle production line operation stage.
[0039] Successful first-stage drive data calibration refers to successful initialization calibration. After completing the initialization calibration of the electric seat in step S100, the vehicle terminal needs to analyze the calibration results. Based on the result analysis, the vehicle terminal determines whether the initialization calibration was successful. If the calibration is successful, the intelligent cloud-controlled vehicle enters the vehicle production line operation phase (i.e., the intelligent cloud-controlled vehicle enters the vehicle production line operation phase). Figure 3 As shown, Figure 3 The method for analyzing the calibration results of the initial calibration in this application is illustrated in the following schematic diagram. Specifically, after the vehicle-mounted terminal completes the initial calibration of the electric seat in step S100, the result analysis of the initial calibration results can be found in [reference needed]. Figure 3 The steps shown are as follows:
[0040] Step S110: Determine the calibration range based on standard driving data from the intelligent cloud.
[0041] Standard drive data refers to the standard operating parameters of power seats. The intelligent cloud can obtain the standard drive data through the first barcode information of the power seat. After obtaining the standard drive data, the intelligent motion system transmits the standard drive data to the in-vehicle terminal, which can then determine the calibration range based on the standard drive data.
[0042] Step S120: Determine whether the first drive data is within the calibration range.
[0043] Step S130: If yes, confirm that the first drive data calibration was successful.
[0044] Step S140: If not, determine that the first drive data calibration failed.
[0045] Steps S120 to S140 will be described in a unified manner.
[0046] After obtaining the calibration range in step S110, the vehicle terminal further executes steps S120 to S140. Specifically, after obtaining the calibration range, the vehicle terminal can compare the first driving data with the calibration range. If the first driving data is within the calibration range, it can be determined that the first driving data calibration was successful; if the first driving data is not within the calibration range, it can be determined that the first driving data calibration failed.
[0047] After the vehicle terminal confirms that the first drive data calibration is successful through steps S120 to S140, it reports the information of successful calibration of the first drive data to the intelligent cloud. The intelligent cloud controls the vehicle to enter the vehicle production line operation stage so that the vehicle completes the production line operation stage and moves to the off-line station.
[0048] After determining that the first drive data calibration failed, the vehicle terminal further executes steps S150 and S160.
[0049] Step S150: In response to the first drive data being less than the minimum value of the calibration range, the first drive task is re-executed on the electric seat.
[0050] Specifically, after determining that the first drive data calibration has failed through steps S120 to S140, the vehicle terminal further determines whether the first drive data is less than the minimum value of the calibration range. In response to the first drive data being less than the minimum value of the calibration range, the first drive task is re-executed on the electric seat. See also... Figure 4 As shown, Figure 4 yes Figure 3 The method step S150 shown is illustrated in the diagram. Step S150 can be found in [reference needed]. Figure 4 The method steps shown are implemented, specifically including steps S151 to S155, as follows:
[0051] Step S151: Determine whether the first driving data is less than the minimum value of the calibration range.
[0052] Step S152: In response to the first driving data being less than the minimum value of the calibration range, the intelligent cloud sends the first calibration command to the vehicle terminal again.
[0053] If the first drive data is less than the minimum value of the calibration range, it can be understood as the first drive data calibration failure.
[0054] Step S153: Determine whether the number of times the first calibration command has been issued is less than a preset threshold.
[0055] Step S154: In response to the fact that the number of times the first calibration command is issued is less than a preset threshold, the vehicle terminal re-executes the first drive task for the electric seat.
[0056] After the intelligent cloud sends the first calibration command to the vehicle terminal again, the vehicle terminal determines the number of times the first calibration command has been sent. If the number of times it has been sent is less than a preset threshold, the vehicle terminal drives the electric seat to perform the first driving task according to the preset driving items based on the first calibration command, and obtains the first driving data. For details, please refer to the content described in step S100. The preset threshold can be set according to the actual situation. For example, the preset threshold can be set to 2.
[0057] Step S155: In response to the number of times the first calibration command is issued exceeding a preset threshold, the vehicle terminal determines the problem category and prompts for human intervention.
[0058] If the number of times the first calibration command is issued exceeds a preset threshold, for example, more than 2 times, manual intervention is required. The vehicle terminal and / or the control module of the electric seat determine the type of problem that caused the first drive data calibration failure, such as motor failure, short circuit / short circuit, power failure, or obstacle encounter. The vehicle terminal uploads the problem type to the intelligent cloud and displays it on the central control screen of the vehicle terminal, prompting manual intervention for repair. This allows operators to quickly locate and resolve the fault, thereby effectively improving the efficiency of calibration fault troubleshooting. After manual repair is completed, the first calibration command is manually triggered on the vehicle terminal so that the vehicle terminal can re-initialize and calibrate the electric seat.
[0059] Step S160: In response to the first drive data being greater than the maximum value of the calibration range, the first drive data is overwritten with standard drive data, and the electric seat is controlled to enter the vehicle production line operation stage.
[0060] Specifically, if the first drive data is greater than the maximum value of the calibration range, it can be understood that the electric seat can drive normally within the calibration range of drive data. Therefore, the standard drive data is used to cover the first drive data already memorized in the smart cloud and the vehicle terminal, so as to use the standard drive data as the parameter for this initial calibration, that is, to use the standard drive data as the first drive data for successful calibration, and control the electric seat to enter the vehicle production line operation stage.
[0061] Unlike existing technologies, the calibration system of this application uses the cooperation between the intelligent cloud and the vehicle system to analyze the results of the initial calibration based on the method steps of S110 to S160. This can effectively reduce human intervention and thus effectively improve the calibration efficiency of electric seats.
[0062] Step S300: In response to the completion of the vehicle production line operation phase and the vehicle containing the electric seat being located at the off-line workstation, the electric seat is driven to perform the second driving task according to at least one of the preset driving items according to the second calibration instruction, and the second driving data is obtained.
[0063] Specifically, the vehicle production line operation phase refers to the vehicle assembly phase of other components during the overall vehicle assembly process. In other words, after the initial calibration of the electric seat is completed, the vehicle still needs to assemble other components to complete the overall vehicle assembly. The vehicle's off-line workstation refers to the workstation where preparations are made before the vehicle is taken off the line after all components have been assembled. After the intelligent cloud, in conjunction with the vehicle-mounted terminal, completes the initial calibration of the electric seat through steps S100 to S200, the intelligent cloud monitors the vehicle in real time through its connected external devices. Upon detecting that the vehicle has entered the off-line workstation, it sends a second calibration command to the vehicle-mounted terminal. This allows the vehicle-mounted terminal to perform a second calibration of the electric seat according to the second calibration command. Specifically, the vehicle-mounted terminal drives the electric seat to perform a second driving task according to at least one of the preset driving items, and acquires the second driving data.
[0064] The vehicle-mounted terminal, according to the second calibration, drives the electric seat to perform a second driving task based on at least one of the preset driving items. This can be understood as the second driving task being one or more of the first driving tasks, and the number of driving items in the second driving task being less than the number of driving items in the first driving task. The purpose of the second calibration is to detect whether the electric seat changes during the vehicle operation phase between the calibration station and the off-line station, thereby improving the calibration accuracy of the calibration system for the electric seat and ensuring the overall vehicle quality. Therefore, during the second calibration process, the vehicle-mounted terminal selects one or more driving items from the driving items of the first driving task as driving items for the second driving task to perform the second calibration of the electric seat. This reduces the number of driving items in the second calibration, effectively improving the calibration efficiency of the electric seat. For example, in some embodiments, the driving item corresponding to the first driving task is bidirectional double-stroke stall zero-point detection, and the driving item corresponding to the second driving task is unidirectional single-stroke stall zero-point detection. This effectively simplifies the driving items of the second driving task, thereby effectively improving the calibration efficiency of the second calibration, and consequently, effectively improving the calibration efficiency of the electric seat.
[0065] Optionally, in some embodiments, the second driving task can be selected selectively. If, during the calibration of the first driving data, an error driving item corresponding to data that is less than the minimum value of the calibration range is found, the second driving task is determined based on the error driving item. Specifically, the data that is less than the minimum value of the calibration range refers to the data in the first driving data that is less than the calibration range, i.e., the data in the first driving data that failed calibration. Therefore, the error driving item corresponding to the data that is less than the minimum value of the calibration range is taken as the driving item of the second driving task. In this way, during the second calibration process, the vehicle terminal can recalibrate the driving items that have failed calibration before, thereby reducing the probability that the driving items that have failed calibration before will fail calibration again without being detected.
[0066] Optionally, before the vehicle terminal drives the electric seat to perform the second driving task according to at least one of the preset driving items based on the second calibration, the vehicle terminal may also detect whether the vehicle where the electric seat is located meets the seat calibration conditions, wherein the seat calibration conditions include: there is no user on the electric seat, the vehicle doors are closed, the vehicle gear is in the parking gear, and / or the vehicle's power status meets the calibration requirements.
[0067] Specifically, after receiving the second calibration command, the vehicle terminal uses occupant detection sensors to check if anyone is inside the vehicle (whether a user or operator is present). When someone is detected in any seat, a vehicle safety alarm is triggered, and the central control screen displays "Seat calibration in progress, please exit the vehicle," reminding the occupants to leave the vehicle. If no one is detected inside the vehicle, the vehicle terminal further checks the vehicle's door status, vehicle gear status, and vehicle power status. If the vehicle terminal detects that the vehicle doors are closed, the vehicle is in park, and the vehicle's power status meets the calibration requirements, the vehicle terminal determines that the vehicle containing the electric seat meets the seat calibration conditions and performs initial calibration of the electric seat in step S300. For example, after the vehicle terminal determines that the vehicle where the electric seat is located meets the seat calibration conditions, the vehicle terminal sends a second calibration command to the control module of the electric seat, so that the control module controls multiple motors of the electric seat to drive simultaneously based on the second calibration command, so that each motor performs a second driving task. The second driving task can be unidirectional single-stroke stall learning (or unidirectional single-stroke stall zero-point detection). The vehicle terminal records the second driving data and uploads the second driving data to the intelligent cloud.
[0068] There is a long production line operation phase between the calibration station and the off-line station. During the production line operation phase, there are various factors that can affect the function of the electric seats. For example, the electric seats may be bumped or blocked by debris during the production line operation phase. The off-line station is the last station on the vehicle production line. Therefore, performing a second calibration on the electric seats at the off-line station can effectively improve the success rate of electric seat calibration and thus effectively reduce the failure rate of electric seats.
[0069] Step S400: Match the first drive data with the second drive data, and determine the calibration result of the electric seat based on the matching result.
[0070] After the vehicle terminal obtains the second drive data in step S300, if the first drive task and the second drive task are the same, for example, if the first drive task is unidirectional single-stroke stall learning and the second drive task is also unidirectional single-stroke stall learning, the vehicle terminal can directly match the first drive data with the second drive data. If the first drive data and the second drive data match successfully, it means that the electric seat calibration is successful and the vehicle can be rolled off the production line normally. If the first drive data and the second drive data do not match successfully, the vehicle terminal will then calibrate the electric seat again using the methods described in steps S100 to S400 to ensure that the electric seat can function normally after the vehicle is rolled off the production line.
[0071] If the first driving task differs from the second driving task—for example, if the first driving task is bidirectional dual-stroke stall zero-point detection and the second driving task is also bidirectional dual-stroke stall zero-point detection—the on-board terminal acquires the common driving items of the first and second driving tasks and filters out the third driving data of the common driving items from the first driving data to match the third driving data with the second driving data. If the third driving data matches the second driving data successfully, it indicates that the electric seat calibration is successful and the vehicle can be rolled off the production line normally. If the third driving data does not match the second driving data, the on-board terminal calibrates the electric seat again using the methods described in steps S100 to S400 to ensure that the electric seat can function normally after the vehicle rolls off the production line.
[0072] Unlike existing technologies, in the calibration method of this application, the on-board terminal performs a first calibration and a second calibration of the electric seat at both the calibration station and the off-line station. The off-line station is the last station before the vehicle is ready to leave the production line. There is a long production line operation phase between the calibration station and the off-line station. During the production line operation phase, there are various factors that can affect the seat function of the electric seat. For example, the electric seat may be bumped or blocked by debris during the production line operation phase. Therefore, at the off-line station, the electric seat is driven to perform a second driving task to perform a second calibration of the electric seat. The second calibration is used to determine the fault status of the electric seat after the production line operation phase. Based on the fault status, further calibration processing of the electric seat is carried out. This improves the success rate of electric seat calibration, thereby effectively reducing the failure rate of the electric seat and thus effectively improving the production quality of the vehicle.
[0073] like Figure 5 As shown, Figure 5 This is a schematic diagram of the method steps of the second embodiment of the calibration method of this application. The calibration method can be found in [reference needed]. Figure 1 The method steps shown are implemented, specifically including steps S500 to S1000, as follows:
[0074] Step S500: In response to the vehicle containing the electric seat being located at the calibration station, obtain the first seat barcode information of the electric seat, and drive the electric seat to perform the first driving task according to the preset driving items according to the first calibration instruction, and obtain the first driving data.
[0075] Specifically, the intelligent cloud can obtain the first seat barcode information of the electric seat when the vehicle containing the electric seat is in the calibration station, and then obtain the parameter information of the electric seat based on the first seat barcode information. Of course, the intelligent cloud can also obtain the first seat barcode information through step S103, which will not be described in detail here. The specific implementation method of the vehicle terminal driving the electric seat to perform the first driving task according to the first calibration instruction and the preset driving items, and obtaining the first driving data, can be found in step S100, which will not be described in detail here.
[0076] Step S600: When the first drive data calibration is successful, control the electric seat to enter the vehicle production line operation stage.
[0077] For a detailed implementation of step S600, please refer to the detailed implementation of step S200, which will not be described in detail here.
[0078] Step S700: In response to the completion of the vehicle production line operation phase and the vehicle containing the electric seat being located at the off-line workstation, obtain the second seat barcode information of the electric seat.
[0079] The intelligent cloud can retrieve the seat barcode information of the electric seat again when the vehicle with the electric seat is at the off-line workstation, that is, the second seat barcode information, in order to obtain the parameter information of the electric seat based on the second seat barcode information.
[0080] Step S800: Match the first seat barcode information and the second seat barcode information, and determine whether the match is successful.
[0081] Step S900: If the matching is successful, drive the electric seat to perform the second driving task according to at least one of the preset driving items according to the second calibration instruction, obtain the second driving data, match the first driving data with the second driving data, and determine the calibration result of the electric seat according to the matching result.
[0082] Step S1000: If matching fails, perform the first drive task on the electric seat.
[0083] Steps S800 to S1000 will be described in a unified manner.
[0084] The intelligent cloud system matches the first and second seat barcode information to determine whether the electric seat has been replaced during the process from the calibration station to the off-line station. If the first and second seat barcode information match successfully, it means that the electric seat has not been replaced. If the first and second seat barcode information fail to match, it means that the seat has been replaced.
[0085] If the barcode information of the first seat fails to match the barcode information of the second seat, the vehicle terminal can directly recalibrate the replaced electric seat through steps S100 to S400, that is, perform the first drive task on the electric seat to ensure that the electric seat can perform the seat function normally after the vehicle is off the production line, thereby avoiding the occurrence of missed calibration, and thus effectively improving the success rate of electric seat calibration, so as to effectively reduce the failure rate of electric seats.
[0086] If the barcode information of the first seat and the barcode information of the second seat are successfully matched, the vehicle terminal drives the electric seat to perform the second driving task according to the second calibration instruction and at least one of the preset driving items, obtains the second driving data, and matches the first driving data with the second driving data. Based on the matching result, the calibration result of the electric seat is determined. For specific implementation methods, please refer to steps S300 to S400, which will not be described in detail here.

[0094] In summary, in the calibration method of this application, the on-board terminal performs a first calibration and a second calibration of the electric seat at the calibration station and the off-line station, respectively. The off-line station is the last station before the vehicle is ready to leave the production line. There is a long production line operation phase between the calibration station and the off-line station. During the production line operation phase, there are various factors that affect the seat function of the electric seat. For example, the electric seat may be bumped or blocked by debris during the production line operation phase. Therefore, at the off-line station, the electric seat is driven to perform a second driving task to perform a second calibration of the electric seat. The second calibration determines the fault status of the electric seat after the production line operation phase. Based on the fault status, further calibration processing of the electric seat is carried out. This improves the success rate of electric seat calibration, thereby effectively reducing the failure rate of the electric seat and thus effectively improving the production quality of the vehicle.
