With the continuous advancement of technology, some gesture recognition functions inside car cabins have also appeared on the market. However, the existing gesture recognition inside car cabins is mostly implemented by camera image recognition, which has obvious disadvantages. Image recognition is only a flat recognition plus algorithm processing, and there is a problem of misoperation. In addition, the existing seat position memory lacks self-learning and adaptive capabilities: the existing seat adjustment system usually works based on preset algorithms and lacks self-learning and adaptive capabilities, so it cannot adapt well to the needs of different passengers.

DETAILED DESCRIPTION
[0017] Reference is made to Figure 1-2As shown, this embodiment provides a car seat posture adaptive system based on a TOF sensor, comprising: a front seat TOF sensor 2 installed above a front seat 1, a rear seat TOF sensor 4 installed above a rear seat 3, and a seat posture position adaptive adjustment system 5 integrated in a vehicle controller; the front seat TOF sensor 2 and the rear seat TOF sensor 4 scan the three-dimensional position data of the seat in real time through infrared light reflection (light pulse), and the model of the front seat TOF sensor 2 and the rear seat TOF sensor 4 is VL53L8CX,
[0018] The front seat TOF sensor 2 and the rear seat TOF sensor 4 are electrically connected to the seat posture position adaptive adjustment system 5. The seat posture position adaptive adjustment system 5 is used to distinguish occupants and record occupant postures based on infrared light scanning, store occupant seat posture positions, and automatically adjust corresponding positions after the corresponding occupants sit back in each seat according to the occupant seat posture position memory. The seat posture position adaptive adjustment system 5 is connected to the vehicle CAN bus. The seat posture position adaptive adjustment system 5 is connected to the front seat drive motor controller 6 and the rear seat drive motor controller 7 through the vehicle CAN bus. The seat posture position adaptive adjustment system 5 includes: a TOF sensor control module 501, an occupant seat posture position information storage module 502, and a gesture recognition module 503; the TOF sensor control module is used to control the front seat TOF sensor and the rear seat TOF sensor to perform infrared light scanning, identify and distinguish occupants and record occupant postures; the occupant seat posture position information storage module 502 is used to store the recognition results of the TOF sensor control module 501 and the seat adjustment gestures pre-entered by the gesture recognition module 503; the gesture recognition module 503 is used to complete the posture adjustment of the relevant seats based on the TOF sensor scanning and identifying the occupant's gestures.
[0019] Workflow:
[0020] Step S1: Scanning the three-dimensional position data of the front seat 1 and the rear seat 3 in real time through the front seat TOF sensor 2 and the rear seat TOF sensor 4;
