Intelligent adjusting system and method for car driver seat based on limb length predicting

Abstract

The invention discloses an intelligent adjusting system and method for a car driving seat based on limb length predicting. The intelligent adjusting method comprises the following steps that image information is obtained through a camera; a driver in an image is subjected to face comparison, if the driver in the image is an in-database driver, seat position and backrest angle information which corresponding to the driver in a database are called to automatically adjust the seat, if no matched driver exists, the subsequent steps are conducted; human body example cutting and articulation joint positioning are conducted on the image through a convolutional neural network, and a human body skeleton model is formed; according to the image information, articulation joint information and camera height information, the pixel scale in the image is determined, and accordingly the height and the limb length of the driver are predicted; and according to a height predicting value and a limb lengthpredicting value of the driver, a limb length-seat position and backrest angle information corresponding table in the database is matched, thus the seat position and backrest angle information is obtained, and a motor is controlled by the controller to automatically adjust the seat. The intelligent adjusting system can automatically and accurately adjust the car driving seat without manual operation.

Description

technical field [0001] The invention relates to the technical field of automobile seat adjustment, in particular to an intelligent adjustment system and method for an automobile driver's seat based on limb length prediction. Background technique [0002] The car seat is the part in the car that has the most contact with the driver's body. The position of the seat directly affects the driver's driving posture. An inappropriate seat position will make the driver drive the car in an uncomfortable posture, thereby increasing the driver's fatigue. Fatigue can even affect the normal operation of the driver. Therefore, car seat adjustment is related to the comfort and safety of driving, and is what the driver needs to focus on before driving the car. [0003] Car seat adjustment technology has mainly experienced three historical stages of development: (1) fixed or less-degree-of-freedom adjustable seat stage; (2) motor-adjustable seat stage; (3) seat with memory adjustment function...

AI Technical Summary

Problems solved by technology

[0004] At this stage, some models have memory seats, which can automatically adjust the seat for the driver who has saved the seat position information. However, for the driver who drives a certain car for the first time, he must manually adjust the seat front and rear, height position and backrest angle etc., the adjustment process is relatively cumbersome, and some drivers often ignore the seat position before driving the car, and directly drive with a seat position that is not suitable for them, which will inevitably affect the comfort and safety of driving
