[0002] The existing intelligent control methods of vehicle seats are relatively simple, such as physical button control, touch screen control, etc. With the continuous advancement of technology, some gesture recognition functions inside car cockpits have also appeared on the market. However, the existing gesture recognition inside car cockpits is mostly implemented by camera image recognition, which has obvious disadvantages. Image recognition is only a plane 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 a preset algorithm, lacks self-learning and adaptive capabilities, and therefore cannot adapt well to the needs of different occupants.

[0003] In view of the above problems, the purpose of the present invention is to provide a car seat posture adaptive system and method based on TOF sensor, which is used to realize active adaptive adjustment of seat posture position through TOF sensor to overcome the shortcomings of the above-mentioned prior art.

[0004] The present invention provides a car seat posture adaptive system based on TOF sensor, comprising: a front seat TOF sensor installed above the front seat, a rear seat TOF sensor installed above the rear seat, and a seat posture position adaptive adjustment system integrated in a vehicle controller; the front seat TOF sensor and the rear seat TOF sensor scan the three-dimensional position data of the seat in real time through infrared light reflection (light pulse), the front seat TOF sensor and the rear seat TOF sensor are electrically connected to the seat posture position adaptive adjustment system, the seat posture position adaptive adjustment system is used to distinguish occupants and record the occupant's body shape according to infrared light scanning recognition, and store the occupant's seat posture position, and automatically adjust the corresponding position after the corresponding occupant sits back in each seat according to the occupant's seat posture position memory, the seat posture position adaptive adjustment system is connected to the vehicle CAN bus, and the seat posture position adaptive adjustment system is connected to the front seat drive motor controller and the rear seat drive motor controller through the vehicle CAN bus.

[0005] As a preferred embodiment of the present invention, the seat posture position adaptive adjustment system comprises: a TOF sensor control module, an occupant seat posture position information storage module, and a gesture recognition module;

[0006] The TOF sensor control module is used to control the front seat TOF sensor and the rear seat TOF sensor to scan and identify the occupants with infrared light and record the occupants' postures;

[0007] The passenger seat posture position information storage module is used to store the recognition result of the TOF sensor control module and the seat adjustment gesture action pre-entered by the gesture recognition module;

[0008] The gesture recognition module is used to scan and recognize the gestures of the passengers according to the TOF sensor to complete the posture adjustment of the relevant seats.

[0009] Another object of the present invention is to provide a control method for a vehicle seat posture adaptive system based on a TOF sensor, which specifically comprises the following steps:

[0010] Step S1: Scanning the three-dimensional position data of the front seats and the rear seats in real time through the front seat TOF sensor and the rear seat TOF sensor;

[0011] Step S2: When the occupant leaves the seat, the seat posture position adaptive adjustment system actively completes self-learning of the seat posture position memory before the occupant leaves, which serves as the basis for adaptive adjustment when the occupant sits on the seat next time;

[0012] Step S3: using the infrared light scanning result in step S1 to identify and distinguish the passenger information, and determine whether the passenger is the recorded passenger. When it is determined that the recorded passenger sits back in the corresponding seat, the seat posture position adaptive adjustment system controls each seat to automatically adjust the corresponding position.

[0013] Step S4: When the seat occupied by the occupant needs to adjust its posture, the occupant completes the corresponding gesture action, uses the TOF sensor control module to control the TOF sensor at the corresponding position to perform a scanning gesture action, and then uses the gesture recognition module to identify the relevant seat adjustment corresponding to the specific action, and controls each seat to automatically adjust the corresponding position through the seat posture position adaptive adjustment system.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention realizes the self-learning and self-adaptation capabilities of the system by introducing a self-learning and self-adaptation mechanism, and can better meet the needs of different passengers for seats.

[0016] 2. The present invention replaces the camera recognition in the prior art by adding a TOF sensor. The TOF sensor distinguishes the occupants and records the occupants' body postures based on infrared light scanning and recognition, and can automatically adjust the corresponding positions after the corresponding occupants sit back in their seats based on the stored occupant seat posture and position memory.

[0017] 3. The present invention realizes the solution and method of intelligent seat control and adjustment and adaptive adjustment system, which effectively improves the comfort of automobile seats. BRIEF DESCRIPTION OF THE DRAWINGS
