摘要
针对传统车辆制动系统受电机和液压响应共同作用的差异影响,造成制动系统控制效果较差的问题,基于MATLAB和Simulink仿真平台,构建一个电机-液压复合制动系统策略框架;并在电-液响应特性的基础上,提出电机与ABS的协调控制策略;基于三种工况,对提出的控制策略和系统策略框架进行实验验证。实验表明,提出的策略可有效解决电机与液压复合制动问题,在电机与ABS复合制动仿真实验中,车辆在1.68 s时可实现电机制动力退出,滑移率保持在15%左右。由此可知,电机和ABS共同作用时的制动矛盾可有效降低,整车制动系统的稳定性和安全性显著提升。
For the traditional vehicle brake system is affected by the motor and hydraulic response,construct a motor-hydraulic composite brake system strategy framework based on MATLAB and Simulink simulation platform,propose the coordinated control strategy between motor and ABS,and verify the proposed control strategy and system strategy framework based on the three working conditions.The experiment shows that the strategy proposed here can effectively solve the problem of motor and hydraulic composite braking.In the motor and ABS composite braking simulation experiment,the vehicle can realize the electric mechanism power exit at 1.68s,and the slip rate is maintained at about 15%.Therefore,the braking contradiction between the motor and the ABS together can be effectively reduced together,and the stability and safety of the vehicle braking system can be significantly improved.
