Problems solved by technology

[0004] The existing road condition detection devices mostly use camera devices to detect road slopes and road obstacles, which requires a large amount of information processing, high performance requirements for the control system, and low detection reliability
The existing technologies for adjusting the vehicle suspension system mostly adjust the suspension heights of different wheels of the vehicle according to the detected slope of the road in front of the vehicle to maintain the vehicle posture, or adjust the suspension height of the vehicle in combination with the vehicle speed. Not only the adjustment method is single, but also The detected road conditions cannot fully represent the road conditions where the vehicle is located, and the effect on improving vehicle safety and comfort is limited

Embodiment Construction

[0030] In the present invention, unless otherwise stated, the orientation or positional relationship indicated by the orientation words such as "front, rear, left, right, upper and lower" is the actual use state of the described device or component. The azimuth or position relationship at the time, wherein the normal driving direction of the vehicle is "forward". In addition, in the present invention, "left tilt" is used to indicate an inclined state in which the left side of the road surface is lower and the right side is higher, and "right tilt" is used to indicate an inclined state in which the right side of the road surface is lower and the left side is higher.

[0031] In the description of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, the term "connection" may be a fixed connection or a detachable connection. Connection, or an ...

Abstract

The invention relates to vehicle control, and discloses a method for adjusting a vehicle suspension system according to road conditions, which comprises the following steps of: projecting latticed marking lines to a road surface in front of a vehicle; detecting grid information of a marking line grid formed on the road surface, wherein the grid information of the marking line grid comprises the width, the length and the deformation degree of the grid; road condition information of the road surface is calculated according to the detected grid information of the mark line grid, wherein the road condition information comprises road surface flatness, road surface gradient and road surface obstacle information; and the current vehicle speed is obtained, and a vehicle suspension system is adjusted in time according to the vehicle speed and the road condition information. According to the method, the road condition information can be better detected, the vehicle suspension system is accurately adjusted, and the driving comfort is effectively improved. The invention further discloses a vehicle suspension control device.

Description

technical field [0001] The present invention relates to vehicle control, in particular to a method for adjusting a vehicle suspension system according to road conditions. In addition, the present invention also relates to a vehicle suspension control device. Background technique [0002] With the popularity of vehicle applications, people have higher and higher requirements for vehicle driving safety and comfort, and vehicle suspension system has a great impact on vehicle safety and comfort. In order to meet market demand, vehicle suspension system and its Control technology is also getting more and more attention. [0003] Different road conditions have different requirements for the suspension system of the vehicle.
