基于单轮差动制动的汽车横向稳定性控制研究及仿真分析

Vehicle Lateral Stability Control Research and Simulation Analysis Based on the Single Wheel Differential Braking

通过Matlab/simulink搭建了汽车控制系统的仿真结构图,分析了单轮差动制动的横向稳定性控制,对在连续变道工况下行驶的汽车进行了单轮差动制动的仿真分析。仿真结果表明,单轮差动制动的制动方式可以大幅降低质心侧偏角、横摆角速度和侧向加速度的幅值,提高了汽车的行驶稳定性。

The simulation diagram of the vehicle control system was built by Matlab/simulink. The lateral stability control of single wheel differential braking was analyzed. To the car traveling in the continuous variable road conditions, simulation analyses based on the single wheel differential braking were carried out. The simulation result shows that the single wheel differential braking can greatly reduced the amplitude of the side slip angle, the yaw rate and the lateral acceleration. And the single wheel differential braking can improve the driving stability of the car.
