[0056] See also Figure 1 , is a schematic diagram of a vehicle seat control mechanism provided in an embodiment of the present application. Figure 1As shown, the vehicle seat control mechanism provided in the embodiment of the present application includes a seat controller 101, a slide rail motor 103 and a locking motor 102. The seat controller 101 controls the slide rail motor 103 to drive the seat to run on the slide rail, and when receiving a stop sliding instruction sent by the vehicle control unit 104, controls the locking motor 102 to lock. It should be noted that the seat controller 101 receives a time synchronization signal sent by the vehicle multimedia control host 105, and the seat controller 101 and the slide rail motor 103 and the locking motor 102 are used to transmit data through the vehicle bus.

[0057] Figure 2 The seat control method provided in the embodiment of the present application is shown in FIG. Figure 1 As an example but not a limitation, the execution subject of this embodiment is Figure 1 The seat controller in this embodiment is not particularly limited here.

[0058] S201: When the seat slides on the slide rail, a stop command is detected, and a distance between the tooth plate of the seat and the tooth window of the slide rail is obtained.

[0059] Figure 3 A schematic diagram of the seat structure provided in the embodiment of the present application, such as Figure 3 As shown, there are 5 tooth plates under the seat, and a plurality of tooth windows are arranged on the slide rail. The two ends of the slide rail are the front end of the slide rail and the rear end of the slide rail, respectively. The seat controller adjusts the position of the seat by controlling the operation of the slide rail motor.

[0060] For example, in the process of controlling the operation of the slide rail motor to adjust the seat position, when a stop command is received from the vehicle-mounted control unit, it is necessary to determine the position of the tooth plate of the seat in the slide rail, and drive the slide rail motor to continue sliding according to the current positional relationship between the tooth plate and the tooth window, so that the tooth plate can fall into the tooth window.

[0061] In an embodiment of the present application, when a command to stop controlling the slide motor to adjust the seat position is received, the sliding direction of the seat is determined, and the distance between the tooth plate and the tooth window is determined according to the sliding direction of the seat. Exemplarily, the sliding direction of the seat is determined according to the operating parameters of the slide motor before the stop command is received. After determining the sliding direction, the sliding distance of the seat in the sliding direction is obtained according to the Hall information of the operation of the slide motor.

[0062] Exemplarily, the specific process of obtaining the sliding distance of the seat in the sliding direction according to the Hall information of the operation of the slide motor is: determine the operation signal of the slide motor in the sliding direction; obtain the sliding distance according to the operation signal and the preset unit distance, wherein the operation signal is the accumulated Hall signal value when the slide motor runs in the sliding direction, and the preset unit distance is the sliding distance of the seat when the slide motor runs one Hall signal. It should be noted that the slide motor is a brushless DC motor, and the accumulated Hall signal values ​​of different sliding directions, that is, the rotation data of the rotor, are stored inside the slide motor. Specifically, the sliding distance of the seat when the slide motor runs one Hall signal and the accumulated Hall signal value can determine the sliding distance in the current sliding direction.

[0063] It should be noted that according to Figure 3 The positional relationship between the seat and the slide rail shown in the figure sets the initial distance between the seat and each tooth window as the distance between the seat's locking tooth plate and each tooth window when the seat is in the extreme position. Figure 3 As shown in the figure, when the limit position is the front end of the slide rail, the locking tooth plate is the last tooth plate of the seat. Figure 3 When the limit position is at the rear end of the slide rail, the locking tooth plate is the first tooth plate of the seat. Figure 3 Tooth plate 5. When the seat slides on the slide rail, the minimum distance in the remaining distance between the seat and each tooth window is used as the spacing between the tooth plate of the seat and the tooth window of the slide rail.

[0064] S202: If the distance is greater than the preset distance, control the slide rail motor to operate according to the first duty cycle until the distance is less than or equal to the preset distance.

[0065] Exemplarily, the first duty cycle is set to be the driving duty cycle of the current slide rail motor when a stop command is received.

[0066] In the embodiment of the present application, when the spacing is greater than the preset distance, it can be determined that the distance between the tooth plate of the seat and the nearest tooth window cannot meet the distance for the tooth plate to directly fall into the tooth window. Exemplarily, in order to improve the adjustment efficiency of the seat, when the spacing is greater than the preset distance, the slide rail continues to run for a distance according to the current running speed, so that the tooth plate of the seat can quickly reach the nearest tooth window position.

[0067] S203: If the distance is less than or equal to the preset distance, control the slide rail motor to run at a preset speed for a preset time period.

[0068] In the embodiment of the present application, when the determined minimum distance between the tooth plate and the tooth window is less than or equal to the preset distance, it is considered that the distance between the tooth plate and the tooth window is close enough, and there is no need to manually adjust the position of the seat. By driving the slide rail motor to run at a preset speed and a preset time period, the tooth plate of the seat can be dropped into the tooth window to achieve the purpose of limiting the seat position. For example, the preset distance is set to 7.5 mm.

[0069] Exemplarily, by reducing the speed of the slide motor, the tooth plate can fall into the tooth window more smoothly. Specifically, the duty cycle of the slide motor can be reduced according to a preset ratio to achieve the purpose of reducing the speed of the slide motor. The preset ratio is the percentage of reduction of the duty cycle per unit time. Specifically, the preset ratio is reduced by 10% every 100ms.

[0070] Exemplarily, when the duty cycle of the slide rail motor is reduced to the second duty cycle, the slide rail motor is controlled to operate at the second duty cycle within a preset time period, wherein the second duty cycle corresponds to a preset rate. Specifically, the second duty cycle is 30%, and the preset time period is 200ms. In the actual operation of the slide rail motor, the duty cycle of the slide rail motor is reduced according to the preset ratio. When the duty cycle of the slide rail motor is reduced to 30%, the slide rail motor is driven to continue to operate at a speed corresponding to the 30% duty cycle for 200ms.

[0071] It should be noted that in S202, the first duty cycle can also be set to be fixed, that is, the first duty cycle is set to be greater than the second duty cycle set in the step of executing the preset time period at a preset rate, so that the slide rail motor can adjust the distance at a faster speed according to the first duty cycle, and then drive the slide rail motor with a relatively small second duty cycle, so that the rate at which the tooth plate of the seat falls into the tooth window is smaller, thereby reducing the impact.

[0072] S204: Stop running the slide rail motor so that the tooth plate of the seat falls into the tooth window of the slide rail.

[0073] In an embodiment of the present application, after the slide rail motor that controls the seat runs at a preset speed for a preset time period, when the slide rail motor has adjusted the position of the tooth plate of the seat to the corresponding position of the tooth window, the drive of the slide rail motor is stopped and the tooth plate of the seat can fall into the tooth window of the slide rail.

[0074] The seat control method provided in this embodiment, when the slide rail motor stops sliding, if the minimum spacing between the tooth plate and the tooth window is greater than a preset distance, the slide rail motor is set to operate according to a first duty cycle, so that the tooth plate of the seat can be quickly adjusted to the nearest tooth window position, and when the spacing is less than or equal to the preset distance, the slide rail motor of the seat is controlled to operate at a preset speed for a preset time period, so that the tooth plate of the seat can fall into the tooth window of the slide rail, thereby improving the adjustment efficiency of the seat.

[0075] Figure 4 The seat control method provided in the embodiment of the present application is shown in FIG. Figure 2 .exist Figure 2 The seat control method provided in the embodiment is based on Figure 4 As shown, in S202, if the distance is greater than the preset distance, the seat control process provided by the embodiment of the present application is as follows:

[0076] S401: When the seat slides on the slide rail, a stop command is detected, and a distance between the tooth plate of the seat and the tooth window of the slide rail is obtained.

[0077] This step and Figure 2 The effect and method implemented by S201 in the embodiment are consistent and will not be described in detail here.

[0078] S402: If the distance is greater than the preset distance, control the slide rail motor to operate according to the first duty cycle until the distance is less than or equal to the preset distance.

[0079] S403: If the distance is less than or equal to the preset distance, control the slide rail motor to run at a preset speed for a preset time period.

[0080] S404: Stop running the slide rail motor so that the tooth plate of the seat falls into the tooth window of the slide rail.

[0081] Embodiments S401 to S404 of the present application are Figure 2 The effects and methods achieved by S201 to S204 in the embodiment are consistent and will not be described in detail here.

[0082] S405: Controlling the locking motor according to the first Hall value so that the locking mechanism of the slide rail reaches a semi-locked state.

[0083] S406: Controlling the locking motor according to the second Hall value so that the locking mechanism of the slide rail changes from a half-locked state to a fully locked state.

[0084] In an embodiment of the present application, when the driving slide rail motor stops, the tooth plate of the seat has fallen into the tooth window. In order to fix the position of the seat and ensure the safety of the passengers, it is necessary to control the locking device to a fully locked state so that the tooth plate can be fixed in the tooth window.

[0085] Exemplarily, the locking motor is controlled according to the first Hall value so that the locking mechanism of the slide rail reaches a semi-locked state, and then the locking motor is controlled according to the second Hall value so that the locking mechanism of the slide rail reaches a fully locked state from the semi-locked state. Specifically, the first Hall value is set to 30 and the second Hall value is set to 20. It should be noted that the first Hall value is determined by the locking device changing from a fully unlocked state to a semi-locked state, and the second Hall value is determined by the locking device changing from a semi-locked state to a fully locked state.

[0086] S407: Control the slide rail motor to run a preset retract distance in the opposite direction of the sliding direction.

[0087] In an embodiment of the present application, when the locking device of the slide rail is in a fully locked state, the slide rail motor is controlled to run a preset retraction distance in the opposite direction of the sliding direction, so that the tooth plate can completely fall into the tooth window, and the tooth plate and the tooth window can be prevented from being squeezed by force for a long time.

[0088] Exemplarily, the set back distance is the distance that the slide rail motor runs in the direction opposite to the sliding direction. The back distance can be determined according to the set back time and the back percentage of the drive slide rail motor. Specifically, the back distance is the running distance of the slide rail motor corresponding to the running of the drive slide rail motor when the slide rail motor runs 200m at a back percentage of 30%.

[0089] S408: Obtain the remaining distance between the seat and each tooth window, and determine the position information of the seat according to the maximum distance among the remaining distances corresponding to each tooth window.

[0090] In the embodiment of the present application, the remaining distance between the seat and each tooth window is stored, that is, the current position information of the seat is recorded, so that when the seat position is adjusted next time, the seat position information can be determined by the maximum distance of the remaining distances corresponding to each tooth window, and the distance and direction to be adjusted can be determined according to the position information in the position adjustment instruction.

[0091] The seat control method provided in this embodiment, on the one hand, when the minimum spacing between the tooth plate and the tooth window is greater than the preset distance, controls the slide rail motor to continue running so that the tooth plate can quickly reach the position of falling into the tooth window; on the other hand, after stopping driving the slide rail motor, not only controls the driving locking motor to timely convert the locking device into a full-lock state, but also controls the slide rail motor to retreat in the opposite direction of the sliding direction so that the tooth plate completely falls into the tooth window, but also can prevent the tooth plate and the tooth window from being squeezed for a long time, thereby improving the stability of the seat.

[0092] Figure 5 The seat control method provided in the embodiment of the present application is shown in FIG. Figure 3 .exist Figure 4 The embodiment provides the basis for the whole process of seat control, such as Figure 5 As shown, the embodiment of the present application provides corresponding processing steps when the seat control is abnormal, which are as follows:

[0093] S501: When it is determined that the seat slides to the limit position, the slide rail motor is stopped, and the limit position is the front end and the rear end of the slide rail.

[0094] In an embodiment of the present application, when it is detected that the seat has slid to the extreme position, i.e., the front end position of the slide rail or the front end position of the slide rail, the drive of the slide rail motor is stopped in time to prevent the seat from derailing.

[0095] S502: When it is detected that the current of the slide rail motor is greater than or equal to the preset current, the slide rail motor is stopped.

[0096] In the process of driving the slide rail motor, the current of the slide rail motor is detected in real time. For example, the preset current is set to the current of the slide rail motor when a stall occurs during the process of driving the slide rail motor. When it is detected that the current of the slide rail motor is greater than or equal to the preset current, it can be determined that the tooth plate falls into the tooth window, and the slide rail motor can no longer continue to run. It is necessary to stop the operation of the slide rail motor in time to avoid malfunction.

[0097] S503: Control the locking motor to lock, so that the locking mechanism of the slide rail reaches a fully locked state.

[0098] In the embodiment of the present application, when the slide rail motor stops running, the locking motor is promptly controlled to lock, so that the locking mechanism of the slide rail reaches a fully locked state. Figure 6 The methods and steps for implementing S605 to S606 in the embodiment are consistent and will not be repeated here.

[0099] The seat control method provided in this embodiment improves the safety of seat control by timely controlling the slide rail motor to stop according to the detected seat position and the current of the slide rail motor, thereby avoiding the situation where the seat derails or the stall current of the slide rail motor is too large.

[0100] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
