Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0022] System example:

[0023] The invention combined with the forward sensing system to improve the vehicle safety control technology has become a research focus in the field of vehicle safety, and more and more vehicles are currently equipped with an electronic control air suspension system (Electronic Control air Suspension), and the electronic control suspension system is controlled by electronic Unit (ECU), solenoid valve, height sensor, air bag and other components. The electronically controlled suspension system can control the stiffness of the suspension system, adjust the damping of the shock absorber, and even adjust the height of the vehicle body according to different road conditions, different load masses, and different driving speeds, so as to make the vehicle travel. The best combination of ride comfort and handling stabilit...

Abstract

The present invention provides a vehicle control method and system based on forward perception, which is combined with the current vehicle height to judge whether the vehicle can pass the obstacle in front, and if it cannot pass the obstacle in front, judge whether the time to adjust the height of the vehicle to the target height is less than If the time for the vehicle to reach the obstacle in front is less than that, adjust the height of the vehicle to the target height, otherwise the driver is reminded to decelerate and brake. The active safety and personal safety of the vehicle are improved by means of early warning and active adjustment of the vehicle height.

Description

technical field [0001] The invention belongs to the technical field of vehicle driving safety, and in particular relates to a vehicle control method and system based on forward perception. Background technique [0002] With the continuous improvement of the level of vehicle intelligence, how to assist the driver to improve the safety and passability of the vehicle has become the focus of research in the automotive industry. Many existing vehicles are equipped with anti-collision detection equipment, which can detect the information of obstacles in front of the vehicle. Determine whether the vehicle has a risk of collision, and avoid obstacles when it is judged that there is a risk. For example, the Chinese invention patent application with the publication number of "CN104442552A" and the title of "vehicle device and its anti-collision system", the patent application judges whether the vehicle chassis is at risk of being scratched by detecting the height of the obstacle and t...
