| 摘 要： | 针对电动汽车电液制动防抱死问题,设计了协调控制系统。首先建立了液压ABS与电机ABS的数学模型,然后根据路面附着系数高低的划分,提出兼顾能量回收的电液制动力协调控制策略,并且在车辆单轮动力学模型的基础上,采用PID控制方法,以理想滑移率为控制目标,分别设计了电机ABS系统和液压ABS系统。在Matlab/Simulink环境下建立仿真模型,对高、低附着系数路面及对接路面的情况进行仿真分析,仿真结果表明:控制策略能够满足控制滑移率的需求,有利于能量回收;系统反应迅速、控制精度高。

| Abstract: | A coordinated control system is designed, aiming to overcome the difficulties in motor and hydraulic anti-lock braking in electric vehicle. Firstly, the mathematical models of motor and hydraulic anti-lock braking system are built, then according to the dividing of tire-road adhesion coefficient and taking account ofenergy recovery, a coordinated control strategy on braking torque is put forward, and based on a single wheel vehicle dynamics model, the motor anti-lock braking system and the hydraulic anti-lock braking system are designed respectively with PID control, aiming to achieve the ideal slip ratio. A simulation model is built in Matlab/Simulink to do simulation on the high,low and joint-adhesion road. The results show that the coordinated control strategy can meet the requirement of controlling slip ratio and have advantage on energy recovery;the system created has fast response and high precise. |
