The main controller 7 is installed at the bottom of the seat cushion. The main controller 7 is connected to the vehicle CAN bus. The main controller 7 is used to calibrate the real-time positions (real-time Hall numbers) of the seat backrest motor, the seat slide rail motor, and the seat leg rest motor according to the feedback signals of the first infrared position signal sensor, the second infrared position signal sensor, and the third infrared position signal sensor, and compensate for the errors of the Hall numbers during the movement of the seat backrest motor mechanism, the seat slide rail motor mechanism, and the seat leg rest motor mechanism.

[0018] The seat backrest motor mechanism 4 in this embodiment includes: an angle adjuster installed between the bottom of the seat backrest and the seat cushion, and a seat backrest motor for driving the angle adjuster. The seat backrest motor Hall sensor is installed in the seat backrest motor for reading the Hall number of the seat backrest motor.

[0019] The seat slide rail motor mechanism 5 in this embodiment includes: a slide rail located at the bottom of the seat, a slider slidably connected to the slide rail, and a seat slide rail motor for driving the slider to slide on the slide rail. The bottom of the seat is fixedly connected to the slider. The seat slide rail motor Hall sensor is installed in the seat slide rail motor for reading the Hall number of the seat slide rail motor.

[0020] The seat leg rest motor mechanism 6 in this embodiment includes a seat leg rest rotatably connected to the end of the seat cushion, and a seat leg rest motor for driving the seat leg rest. The seat leg rest motor Hall sensor is installed in the seat leg rest motor to read the Hall number of the seat leg rest motor.

[0021] The main controller 7 of the seat intelligent control device in this embodiment further includes a position memory module. The position memory module is used to store the position information (motor Hall number) of the seat backrest motor mechanism 4, the seat slide rail motor mechanism 5, and the seat leg rest motor mechanism 6. The seat intelligent control device controls the seat backrest motor mechanism 4, the seat slide rail motor mechanism 5, or the seat leg rest motor mechanism 6 to adjust to the memory position according to the position information in the position memory module.

[0022] The model of the controller 7 in this embodiment is ECU00P201, and the models of the first infrared position signal sensor, the second infrared position signal sensor, and the third infrared position signal sensor are HW00S201.

[0023] Working principle: Since the motor drive parts of the seat backrest motor mechanism 4, the seat slide rail motor mechanism 5, and the seat leg rest motor mechanism 6 all involve gear transmission, there are errors when the motor controls the seat backrest motor mechanism 4, the seat slide rail motor mechanism 5, and the seat leg rest motor mechanism 6 to move to the corresponding positions. During the real-time adjustment process, the user can manually adjust through the buttons according to the needs, and the user can adjust to a comfortable position, so this error can be ignored. However, when using the position memory function, it is automatically adjusted to the corresponding position according to the memorized motor Hall number, so this error cannot be ignored. By adding an infrared position signal sensor for user calibration, the main controller 7 can calibrate the motor position (Hall number) according to the feedback signal of the infrared position signal sensor, realizing position memory and remote precise control, and enhancing the intelligent control of the car cockpit.

[0024] The working process includes the following steps:

[0025] Step S1: Use the main controller 7 connected to the CAN bus to detect whether there is a signal for controlling the seat backrest motor, the seat slide rail motor, or the seat leg rest motor to act.

[0026] Step S2: When no signal for controlling the seat backrest motor, the seat slide rail motor, or the seat leg rest motor to act is detected, the main controller 7 does not turn on the infrared position signal sensor.

[0027] Step S3: When a signal for controlling the seat backrest motor, the seat slide rail motor, or the seat leg rest motor to act is detected, the main controller 7 activates the infrared position signal sensor at the corresponding position, specifically the first infrared position signal sensor, the second infrared position signal sensor, or the third infrared position signal sensor.

[0028] Step S4: The main controller 7 is used to collect the motor Hall numbers in real time, identify and store the real-time position of the seat movement.

[0029] Step S5: The main controller 7 is used to synchronously judge in real time whether the seat back motor mechanism 4, the seat slide rail motor mechanism 5 or the seat leg rest motor mechanism 6 moves to the detection position corresponding to the infrared position signal sensor.

[0030] Step S6: When the main controller 7 detects that the infrared position signal sensor is triggered, the real-time positions (motor real-time Hall numbers) of the seat back motor mechanism 4, the seat slide rail motor mechanism 5 or the seat leg rest motor mechanism 6 are calibrated to supplement the errors of the Hall numbers during the movement process, so as to ensure the accuracy of the seat position state.

[0031] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
