[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] The terms "first" and "second" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited. In addition, the terms "including" and "having" and any of their variations are intended to cover exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0022] The present application provides a calibration method for an electric seat, wherein in the embodiment of the present application, the calibration method is mainly applied to the field of automatic calibration of vehicle electric seats, and at the same time, the calibration method of the present application is also applicable to other corresponding technical fields, and the present application mainly describes the calibration method in detail based on the application of the calibration method in the field of automatic calibration of vehicle electric seats, wherein the execution subject of the calibration method of the present application is a calibration system. Among them, the calibration system includes an intelligent cloud and a vehicle-mounted terminal connected to the intelligent cloud. The intelligent cloud communicates with the vehicle-mounted terminal through communication technology, and cooperates with the vehicle-mounted terminal to realize the calibration of the electric seat. The vehicle-mounted terminal is a vehicle-mounted system set on the vehicle. Compared with the traditional simple electric adjustment of electric seats, today's electric seats integrate advanced intelligent technologies, such as seat massage, heating and ventilation, welcome memory, zero gravity seats, etc. Among them, the functions related to seat memory need to be calibrated for electric seats, such as calibrating the travel of the electric seat in all directions. After the calibration is completed, the seat memory-related functions, that is, the seat functions, can be used normally.

[0023] like Figure 1 As shown, Figure 1 Schematic diagram of the method steps of the first embodiment of the calibration method of the present application. Figure 1 The method steps shown are implemented, specifically including steps S100 to S400, as follows:

[0024] Step S100: In response to the vehicle where the electric seat is located being located at a calibration station, the electric seat is driven to perform a first driving task according to a preset driving item according to a first calibration instruction, and first driving data is acquired.

[0025] When the vehicle in which the electric seat is located runs to the calibration station, the motion system sends a first calibration instruction to the vehicle terminal. The vehicle terminal drives the electric seat to perform the first driving task according to the preset driving project according to the first calibration instruction, and obtains the first driving data to initialize the calibration of the electric seat, which is also called the first calibration. Optionally, the driving project corresponding to the first driving task is a two-way two-stroke stall zero point detection. In other words, the vehicle terminal controls the driving motor of the electric seat to perform a two-way two-stroke stall zero point detection based on the first calibration instruction.

[0026] The calibration system includes an intelligent cloud and a vehicle-mounted terminal. Before the calibration system starts to execute step S100, it is also necessary to perform system initialization to improve the stability of the calibration system during the execution of the calibration method. Figure 2 As shown, Figure 2 Schematic diagram of the method steps for initializing the system of the calibration system of the present application. Figure 2 The method steps shown are implemented, specifically including steps S101 to S104, as follows:

[0027] Step S101: The smart cloud is powered on and connected to the Internet.

[0028] The intelligent cloud is powered and connected to the Internet to ensure the normal operation of the vehicle production line.

[0029] Step S102: The vehicle terminal is connected to the electrical network.

[0030] The vehicle terminal is electrically connected to the Internet so that the vehicle terminal can communicate with the smart cloud to ensure that the vehicle terminal can communicate normally with the smart cloud.

[0031] Step S103: The smart cloud obtains the first seat barcode information of the electric seat.

[0032] The smart cloud obtains the first seat barcode information of the electric seat that needs to be calibrated this time. The smart 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 smart 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: starting the factory mode based on the starting instruction.

[0034] The vehicle terminal is provided with a startup instruction. After the intelligent cloud and the vehicle terminal pass and complete steps S101 to S103, the system initialization preparation can be completed. After the system initialization preparation is completed, the vehicle terminal also needs to receive the startup instruction and enter the factory mode based on the correct startup instruction to cooperate with the intelligent cloud to perform initialization calibration on the electric seat, which can effectively improve the working reliability of the calibration system. Optionally, a command input channel can be set on the vehicle terminal. For example, after the intelligent cloud and the vehicle terminal pass and complete steps S101 to S103, the vehicle's central control screen displays the input startup instruction operation. In response to the user inputting the startup instruction correctly, the vehicle terminal starts the factory mode, and the system initialization is completed based on this calibration system.

[0035] After the system initialization is completed (that is, after the vehicle terminal enters the factory mode), the intelligent cloud monitors the vehicle in real time through the external device connected to it, and after detecting that the vehicle enters the calibration station, it sends the first calibration instruction to the vehicle terminal. The vehicle terminal executes step S100 according to the first calibration instruction to initialize and calibrate the electric seat. Among them, if the vehicle terminal cannot obtain the first calibration instruction issued by the intelligent motion, the calibration station will alarm and remind the fault to promote the operator to manually handle, such as manually issuing the first calibration instruction.

[0036] Optionally, before the vehicle-mounted terminal executes step S100 according to the first calibration instruction to initialize and calibrate the electric seat, the vehicle-mounted terminal may also detect whether the vehicle in which 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's doors are closed, the vehicle's gear is in the parking gear, and / or the vehicle's power status meets the calibration requirements.

[0037] Specifically, after receiving the first calibration instruction, the vehicle terminal detects whether there is anyone in the vehicle (whether there is a user or operator) through the occupant detection sensor. When it is detected that there is someone in any seat, the vehicle safety alarm is triggered, and the central control screen displays "Seat calibration, please exit the vehicle" to remind the vehicle occupants to exit the vehicle. If it is detected that there is no one in the vehicle, the vehicle terminal further detects the door status of the vehicle, the unit status of the vehicle, and the power status of the vehicle. If the vehicle terminal detects that the vehicle door is in a closed state, the gear position of the vehicle is in the parking gear, and the power status of the vehicle meets the calibration requirements, the vehicle terminal determines that the vehicle where the electric seat is located meets the seat calibration conditions, and initializes the calibration of the electric seat through step S100. For example, after the vehicle terminal determines that the vehicle in which the electric seat is located meets the seat calibration conditions, the vehicle terminal sends the first calibration instruction to the control module of the electric seat, so that the control module controls the simultaneous driving of multiple motors of the electric seat based on the first calibration instruction, so that each motor performs the first drive task, wherein the first drive task can be a two-way two-stroke stall learning (or also known as a two-way two-stroke stall zero point detection), the vehicle terminal records the first drive data, and uploads the first drive data to the smart cloud. Based on this, the vehicle terminal automatically completes the determination of the seat calibration conditions, thereby effectively reducing manual participation, and thereby effectively improving the calibration efficiency of the electric seat.

[0038] Step S200: When the first drive data calibration is successful, the electric seat is controlled to enter the vehicle production line operation stage.

[0039] The first drive data calibration success refers to the initialization calibration success. After the vehicle terminal completes the initialization calibration of the electric seat through step S100, it is also necessary to analyze the calibration results of the initialization calibration. The vehicle terminal determines whether the initialization calibration is successful based on the result analysis. If the calibration is successful, the intelligent cloud controls the vehicle to enter the vehicle production line operation stage (that is, the intelligent cloud controls the vehicle to enter the vehicle production line operation stage). Figure 3 As shown, Figure 3 Schematic diagram of the method steps for analyzing the calibration results of the initialization calibration in the calibration method of the present application. After the vehicle terminal completes the initialization calibration of the electric seat in step S100, the calibration results of the initialization calibration are analyzed. Figure 3 The method steps shown are implemented as follows:

[0040] Step S110: Determine the calibration range based on the standard driving data in the smart cloud.

[0041] The standard driving data is the standard working parameter of the electric seat. The smart cloud can obtain the standard driving data through the first seat barcode information of the electric seat. After obtaining the standard driving data, the smart motion transmits the standard driving data to the vehicle terminal, and the vehicle terminal can determine the calibration range based on the standard driving data.

[0042] Step S120: determining whether the first driving data is within a calibration range.

[0043] Step S130: If yes, determine that the first driving data calibration is successful.

[0044] Step S140: If not, determine that the first driving data calibration fails.

[0045] Steps S120 to S140 are collectively described.

[0046] After the vehicle terminal obtains the calibration range through step S110, it further executes steps S120 to S140. Specifically, after obtaining the calibration range, the vehicle terminal can compare the first drive data with the calibration range. If the first drive data is within the calibration range, it can be determined that the first drive data calibration is successful. If the first drive data is not within the calibration range, it can be determined that the first drive data calibration fails.

[0047] After the vehicle terminal determines that the first drive data calibration is successful through steps S120 to S140, the information of successful calibration of the first drive data is reported 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 offline workstation.

[0048] After determining that the first driving data calibration fails, the vehicle terminal further executes step S150 and step S160.

[0049] Step S150: In response to the first driving data being less than the minimum value of the calibration range, re-execute the first driving task on the electric seat.

[0050] Specifically, after determining that the first drive data calibration fails 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, and in response to the first drive data being less than the minimum value of the calibration range, re-executes the first drive task for the electric seat. Figure 4 As shown, Figure 4 yes Figure 3 The method step diagram of step S150 of the method step shown in FIG. Step S150 can be found in Figure 4 The method steps shown are implemented, specifically including steps S151 to S155, which are specifically 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 again sends the first calibration instruction to the vehicle terminal.

[0053] The fact that the first drive data is less than the minimum value of the calibration range can be understood as a failure in the calibration of the first drive data.

[0054] Step S153: Determine whether the number of times the first calibration instruction is issued is less than a preset threshold.

[0055] Step S154: In response to the number of times the first calibration instruction is issued being less than a preset threshold, the vehicle-mounted terminal re-executes the first driving task on the electric seat.

[0056] After the intelligent cloud sends the first calibration instruction to the vehicle terminal again, the vehicle terminal determines the number of times the first calibration instruction is sent. If the number of times the first calibration instruction is sent is less than the preset threshold, the electric seat is driven to perform the first driving task according to the preset driving project according to the first calibration instruction, and the first driving data is obtained. For details, please refer to the content described in step S100. Among them, 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 instruction is issued being greater than a preset threshold, the vehicle-mounted terminal determines the type of problem and prompts for human intervention.

[0058] If the number of times the first calibration instruction is issued is greater than the preset threshold, for example, the number of times the first calibration instruction is issued is greater than 2, manual intervention is required, and the vehicle terminal and / or the control module of the electric seat determine the problem category of the failure of the first drive data calibration, such as motor failure, short circuit / short circuit, power failure or encountering obstacles, etc. The vehicle terminal uploads the problem category to the smart cloud, and displays it on the central control screen of the vehicle terminal, and reminds manual intervention to repair, so that the operator can quickly locate and solve the fault problem, thereby effectively improving the efficiency of troubleshooting calibration faults. When the manual repair is completed, the first calibration instruction is manually triggered on the vehicle terminal so that the vehicle terminal can initialize and calibrate the electric seat again.

[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 the standard drive data, and the electric seat is controlled to enter the vehicle production line operation phase.

[0060] Specifically, the first driving data is greater than the maximum value of the calibration range, which can be understood as the electric seat can be driven and operated normally within the driving data of the calibration range. Therefore, the standard driving data is used to cover the first driving data that has been memorized in the smart cloud and the vehicle-mounted terminal, so that the standard driving data is used as the parameter for this initialization calibration, that is, the standard driving data is used as the first driving data that has been successfully calibrated, and the electric seat is controlled to enter the vehicle production line operation stage.

[0061] Different from the prior art, the calibration system of the present application analyzes the results of the initialization calibration based on the method steps of step S110 to step S160 through the mutual cooperation between the intelligent cloud and the vehicle-mounted system, which can effectively reduce manual participation and effectively improve the calibration efficiency of the electric seat.

[0062] Step S300: In response to the completion of the vehicle production line operation phase and the vehicle where the electric seat is located is located at the off-line workstation, the electric seat is driven to perform a second drive task according to at least one drive item in the preset drive items according to the second calibration instruction, and second drive data is obtained.

[0063] Specifically, the vehicle production line operation stage is the vehicle equipment stage of other parts in the vehicle equipment process. In other words, after the initialization calibration of the electric seat is completed, the vehicle needs to assemble other parts to complete the assembly of the whole vehicle, where the vehicle's offline station refers to the station where the vehicle is prepared before offline after all parts have been assembled. After the intelligent cloud cooperates with the on-board terminal to complete the initialization calibration of the electric seat through steps S100 to S200, the intelligent cloud monitors the vehicle in real time through the external device connected to it, and after detecting that the vehicle enters the offline station, it sends a second calibration instruction to the on-board terminal, so that the on-board terminal performs a second calibration on the electric seat according to the second calibration instruction, that is, the on-board terminal drives the electric seat to perform a second drive task according to at least one drive item in the preset drive items according to the second calibration instruction, and obtains the second drive data.

[0064] The vehicle terminal drives the electric seat to perform the second drive task according to at least one drive project in the preset drive project according to the second calibration. It can be understood that the second drive task is one or more of the first drive task, and the number of drive projects of the second drive task is less than the number of drive projects of the first drive task. The purpose of the second calibration is to detect whether the electric seat changes in the vehicle operation stage between the calibration station and the offline station, so as to improve the calibration accuracy of the electric seat by the calibration system, so as to ensure the vehicle quality of the vehicle. Therefore, during the second calibration process, the vehicle terminal selects one or more drive projects from the drive projects of the first drive task as the drive projects of the second drive task to perform the second calibration on the electric seat, so as to reduce the number of drive projects of the second calibration, so as to effectively improve the calibration efficiency of the electric seat. For example, in some embodiments, the drive project corresponding to the first drive task is a two-way two-stroke stall zero point detection, and the drive project corresponding to the second drive task is a one-way single-stroke stall zero point detection. Based on this, the drive project of the second drive task can be effectively simplified, thereby effectively improving the calibration efficiency of the second calibration, and then effectively improving the calibration efficiency of the electric seat.

[0065] Optionally, in some embodiments, the second driving task can be selected in a targeted manner. If an error driving item corresponding to data that is less than the minimum value of the calibration range appears during the calibration process of the first driving data, 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 is the data in the first driving data that is less than the calibration range, that is, the data that is unsuccessfully calibrated in the first driving data. Therefore, the error driving item corresponding to the data that is less than the minimum value of the calibration range is used as the driving item of the second driving task. In this way, during the second calibration process, the vehicle-mounted terminal can re-calibrate the driving items that have failed to be calibrated, so as to reduce the probability that the driving items that have failed to be calibrated will fail to be calibrated again without being discovered.

[0066] Optionally, before the vehicle-mounted terminal drives the electric seat to perform the second driving task according to the second calibration and at least one of the preset driving items, the vehicle-mounted terminal may also detect whether the vehicle in which 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's doors are in a closed state, the vehicle's gear is in the parking gear, and / or the vehicle's power status meets the calibration requirements.

[0067] Specifically, after receiving the second calibration instruction, the vehicle terminal detects whether there is anyone in the vehicle (whether there is a user or operator) through the occupant detection sensor. When it is detected that there is someone in any seat, the vehicle safety alarm is triggered, and the central control screen displays "Seat calibration, please exit the vehicle" to remind the vehicle occupants to exit the vehicle. If it is detected that there is no one in the vehicle, the vehicle terminal further detects the door status of the vehicle, the unit status of the vehicle, and the power status of the vehicle. If the vehicle terminal detects that the vehicle door is in a closed state, the gear position of the vehicle is in the parking gear, and the power status of the vehicle meets the calibration requirements, the vehicle terminal determines that the vehicle where the electric seat is located meets the seat calibration conditions, and initializes the calibration of the electric seat through step S300. For example, after the on-board terminal determines that the vehicle where the electric seat is located meets the seat calibration conditions, the on-board terminal sends the second calibration instruction to the control module of the electric seat, so that the control module controls the simultaneous driving of multiple motors of the electric seat based on the second calibration instruction, so that each motor performs the second driving task, wherein the second driving task can be one-way single-stroke stall learning (or also called one-way single-stroke stall zero point detection), the on-board terminal records the second driving data, and uploads the second driving data to the smart cloud.

[0068] There is a long production line operation stage between the calibration station and the off-line station. During the production line operation stage, there are many factors that affect the seat function of the electric seat. For example, during the production line operation stage, the electric seat may be bumped or blocked by debris. The off-line station is the last station of the vehicle production line. Therefore, performing a second calibration of the electric seat at the off-line station can effectively improve the success rate of the electric seat calibration, so as to effectively reduce the failure rate of the electric seat.

[0069] Step S400: Match the first drive data with the second drive data, and determine the calibration result of the electric seat according to the matching result.

[0070] After the vehicle terminal obtains the second driving data through step S300, if the first driving task is the same as the second driving task, for example, if the first driving task is a one-way single-stroke stalled learning and the second driving task is also a one-way single-stroke stalled learning, the vehicle terminal can directly match the first driving data with the second driving data. If the first driving data matches the second driving data successfully, it means that the electric seat is calibrated successfully and the vehicle can be offline normally. If the first driving data does not match the second driving data successfully, the vehicle terminal calibrates the electric seat again through the method steps described in steps S100 to S400 to ensure that the electric seat can function normally after the vehicle is offline.

[0071] If the first driving task is different from the second driving task, for example, the first driving task is a two-way two-stroke stall zero point detection, and the second driving task is a two-way two-stroke stall zero point detection, the vehicle-mounted terminal obtains the common driving items of the first driving task and the second driving task, and selects 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 means that the electric seat is calibrated successfully and the vehicle can be offline normally. If the third driving data does not match the second driving data successfully, the vehicle-mounted terminal calibrates the electric seat again through the method steps described in steps S100 to S400 to ensure that the electric seat can normally realize the seat function after the vehicle is offline.

[0072] Different from the prior art, in the calibration method of the present application, the on-board terminal performs the first and second calibrations on the electric seat at the calibration station and the off-line station respectively, wherein the off-line station is the last station before the vehicle is ready to go offline, and there is a long production line operation stage between the calibration station and the off-line station. During the production line operation stage, there are many factors that affect the seat function of the electric seat. For example, during the production line operation stage, the electric seat may be bumped or blocked by debris. Therefore, at the off-line station, the electric seat is driven to perform the second driving task to perform the second calibration on the electric seat, and the fault condition of the electric seat after the production line operation stage is determined through the second calibration, so that the electric seat is further calibrated based on the fault condition, thereby improving the success rate of the electric seat calibration, thereby effectively reducing the failure rate of the electric seat, and further improving the production quality of the vehicle.

[0073] like Figure 5 As shown, Figure 5 Schematic diagram of the method steps of the second embodiment of the calibration method of the present application. Figure 1 The method steps shown are implemented, specifically including steps S500 to S1000, as follows:

[0074] Step S500: In response to the vehicle where the electric seat is located being located at a calibration station, first seat barcode information of the electric seat is obtained, and the electric seat is driven to perform a first drive task according to a preset drive project based on a first calibration instruction, and first drive data is obtained.

[0075] Specifically, the smart cloud can obtain the first seat barcode information of the electric seat when the vehicle where the electric seat is located is at the calibration station, so as to obtain the parameter information of the electric seat according to the first seat barcode information. Of course, the smart cloud can also obtain the first seat barcode information through step S103, which is not described in detail here. Among them, the vehicle terminal drives the electric seat to perform the first drive task according to the preset drive project according to the first calibration instruction, and the specific implementation method of obtaining the first drive data can be specifically referred to in step S100, which is not described in detail here.

[0076] Step S600: When the first drive data calibration is successful, the electric seat is controlled to enter the vehicle production line operation stage.

[0077] The specific implementation of step S600 can refer to the specific implementation of step S200, which will not be described in detail herein.

[0078] Step S700: In response to the vehicle production line operation phase being completed and the vehicle where the electric seat is located being located at the off-line workstation, the second seat barcode information of the electric seat is obtained.

[0079] The intelligent cloud can obtain the seat barcode information of the electric seat again when the vehicle where the electric seat is located is at the off-line workstation, that is, the second seat barcode information, to obtain the parameter information of the electric seat according to 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 match is successful, drive the electric seat to perform a second drive task according to at least one drive item in the preset drive items according to the second calibration instruction, obtain second drive data, match the first drive data with the second drive data, and determine the calibration result of the electric seat according to the matching result.

[0082] Step S1000: If the matching fails, the first driving task is performed on the electric seat.

[0083] Steps S800 to S1000 are collectively described.

[0084] The intelligent cloud matches the first seat barcode information with the second seat barcode information to determine whether the vehicle's electric seat has been replaced in the process from the calibration station to the off-line station. If the first seat barcode information matches the second seat barcode information successfully, it means that the vehicle's electric seat has not been replaced. If the first seat barcode information fails to match the second seat barcode information, it means that the vehicle has replaced the seat.

[0085] If the first seat barcode information fails to match the second seat barcode information, the vehicle-mounted terminal can directly recalibrate the replaced electric seat through steps S100 to S400, that is, perform the first driving task on the electric seat to ensure that the electric seat can perform the seat function normally after the vehicle is offline, thereby avoiding missing labels, and effectively improving the success rate of electric seat calibration to effectively reduce the failure rate of electric seats.

[0086] If the first seat barcode information matches the second seat barcode information successfully, the vehicle terminal drives the electric seat to perform the second drive task according to the second calibration instruction and at least one drive item in the preset drive items, obtains the second drive data, and matches the first drive data with the second drive data, and determines the calibration result of the electric seat according to the matching result. The specific implementation method can be found in steps S300 to S400, and this article will not go into details here.

[0087] The present application also proposes a calibration system, which includes: an intelligent cloud and a vehicle-mounted terminal connected to the intelligent cloud; the intelligent cloud is used to send a first calibration instruction to the vehicle-mounted terminal in response to the electric seat being shown in the vehicle being located at a calibration station; the vehicle-mounted terminal is used to drive the electric seat to perform a first drive task according to a preset drive project according to the first calibration instruction, and obtain first drive data; the intelligent cloud is also used to control the electric seat to enter the vehicle production line operation stage when the first drive data is calibrated successfully; and in response to the completion of the vehicle production line operation stage and the vehicle where the electric seat is located being located at the offline station, send a second calibration instruction to the vehicle-mounted terminal; the vehicle-mounted terminal is also used to drive the electric seat to perform a second drive task according to at least one drive project in the preset drive project according to the second calibration instruction, and obtain second drive data; and is used to match the first drive data with the second drive data, and determine the calibration result of the electric seat according to the matching result.
