摘要
建立混合动力汽车硬件在环仿真系统,研究在各种路面状况下的汽车稳定性控制算法。控制算法包括再生制动和液力制动之间的制动力矩分配、车轮滑移率的滑模控制等。在设计的混合动力汽车稳定性控制硬件在环仿真系统中,选取稳定性控制器和执行器(如制动轮缸、驱动电机)为实物,而汽车(受控对象)的运行状态由计算机仿真。仿真结果表明,基于再生制动、液力制动和滑移率联合控制的车辆稳定性控制算法能够在各种路面条件下提高制动性能,如缩短制动距离、减小侧偏角和横摆角速度的误差。
In this paper,the hardware-in-the-loop simulation system(HILs)of hybrid electric vehicle is established,and the vehicle stability control algorithm under various road conditions is studied.The control algorithm includes the brake moment distribution between regenerative brake and hydraulic brake,and the sliding mode control of wheel slip rate,and so on.In the designed HILs of hybrid electric vehicle stability control,the stability controller and actuator(such as brake wheel cylinder and drive motor)are selected as the hardware,and the running state of the vehicle(controlled object)is simulated by computer.HIL result shows that the vehicle stability control algorithm based on regenerative brake,hydraulic brake and slip rate joint control can improve the brake performance under various road conditions,such as shortening the brake distance,reducing the deviation of side slip angle and yaw angular velocity.
