Vehicle steering anti-collision method and device

Abstract

Embodiments of the present invention provide a vehicle steering anti-collision method and equipment. When the vehicle is turning, the method determines the front wheel rotation angle of the tractor according to the driving speed of the vehicle, and determines the rotation angle at the hinge point according to the front wheel rotation angle of the tractor. and speed, and according to the speed at the hinge point, determine the driving radius of curvature at the hinge point and the driving radius of curvature of the trailer, and determine the tractor according to the driving radius of curvature at the hinge point, the driving radius of curvature of the trailer and the corner at the hinge point The angle formed with the trailer further predicts the area swept by the outer contour of the vehicle when it turns, and judges whether the vehicle can pass the current path. Therefore, without adding more sensor costs, by optimizing the intelligent driving algorithm, according to the planning The route predicts the location of the tractor, trailer and road surface, combines it with road and external vehicle information, determines the rationality of the planned route, and provides new route planning support.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a method and device for avoiding collisions in vehicle steering. Background technique [0002] With the development of social economy and the continuous improvement of people's living standards, vehicles are becoming more and more popular and have more and more functions. They have become an important means of transportation for people to travel. [0003] The existing intelligent driving assistance technology is beginning to be applied in the field of commercial vehicles. The method to solve this problem in the lateral or longitudinal control of the tractor is mainly to deviate a fixed distance to the outside of the lane or reduce the speed of the vehicle when the vehicle is in a curve. [0004] However, the above method cannot judge whether it is suitable for curves with different curvatures, and trailer compartment flick collisions or false decele...
