Intelligent steering wheel adjusting device and method based on different drivers

Abstract

The invention discloses an intelligent steering wheel adjusting device and method based on different drivers. Body size parameters of different drivers are input, the optimal sitting posture positionscorresponding to different drivers are calculated according to the body size parameters of different drivers, and proper positions of steering wheels corresponding to different drivers are determinedaccording to the optimal sitting posture positions corresponding to different drivers; before the drivers get on vehicles, the steering wheels are moved to reference positions which are convenient for the drivers to sit, and then the steering wheels are moved to the proper position corresponding to the drivers after the drivers get on the vehicles. The optimal sitting posture driving positions ofthe drivers and the corresponding proper positions of the steering wheels are calculated by inputting height parameters by the drivers, and the steering wheels are automatically adjusted to the optimal positions so that the drivers with different sizes can obtain the optimal steering wheel control experience and a better visual field, and the driving experience of users is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile seats, and in particular relates to a steering wheel intelligent adjustment device and method based on different drivers. Background technique [0002] Generally, the steering wheel of a car is designed to be adjustable in two or four directions (note: the steering wheel can only be adjusted in two directions along the direction of the upper steering column fixing bracket; Adjustment is four-way adjustment), according to the adjustment method can be divided into manual adjustment and electric adjustment. But regardless of manual adjustment and electric adjustment, the traditional way is that the driver adjusts the steering wheel to a suitable position according to his own experience. Due to differences in the driver's body and experience, it takes a long time to adjust, and even the adjusted actual position is not suitable, which affects the safety of the driver's driving vision and control co...

Problems solved by technology

Such as CN103448785A, the steering wheel is adjusted by monitoring the head / eyes through the sensor. Since the position of the driver's head / eyes is determined by the driver's height characteristics and sitting posture, if the driver's sitting posture is not suitable, it will affect the monitoring of the head / eyes. position, thus affecting whether the adjusted steering wheel position is appropriate

And in the driving process, in order to be safe and avoid fatigue, the head and eyes need to move from time to time, so the monitored head / eye position is not easy to determine; the steering wheel position adjusted accordingly is also uncertain; also as CN104827987A, by obtaining The height of the driver's upper body is used to determine the position of the steering wheel. In practice, there are the following limitations: due to the fuzzy concept of upper body length and the influence of posture, obtaining the upper body length is relatively less convenient and accurate than obtaining the height; and the position and angle of the steering wheel are not only affected by the driver's body. In addition to the influence of length factors, it is also mainly affected by sitting posture
