摘要
本文针对四轮转向汽车车体后轮过度转向,创新性的改进四轮转向轿车后转向执行机构并对其进行控制,使得车辆后轮能实现1到2度角的精确跟随转动,利用Matlab/ Simulink/dsPACE等软件进行仿真,从而为提高车辆的综合稳定性能提供一个技术平台,并最终通过DSP引入实际的前轮转角信号,搭建一个实际反馈系统,进而实现对轿车后轮转向的精确实时控制。
This paper is according to the improving performance organization of rear wheel steering, studying the vehicle when its speed is in the range of medium to high. Through guiding the rear wheel , controlling its steering angle reasonablely , The measure to solve this problem is to make the rear wheels to rotate 1 to 2 degrees in the same direction as the front wheels to compensate, with the use of Simulink/dSPACE/DSP etc, making it rotate some degree in the same direction as the front wheels in time accurately, thus to give a good flat for the four wheel steering technology so that the comprehensive steady performance of the vehicle can be improved.
