This paper develops a parallel hydraulic brake system with electronic hydraulic brake device to meet the requirements of active braking control of active collision avoidance system. When the vehicle needs active braking, the wheel cylinder pressure quickly achieve the desired braking pressure by the electronic hydraulic device. The P- fuzzy PID control algorithm is used to develop the pressure controller. The effect of the pressure controller is verified based on co-simulation with Matlab / Simulink and AMESim. The results indicate that the pressure control meets the requirements of active braking control of this system.%为满足汽车主动避撞系统主动制动的需要,开发了一种基于电控液压制动装置并联式液压制动系统.该系统通过电控液压装置,在需要对车辆进行主动制动时使轮缸压力迅速达到期望制动压力.利用P-模糊PID算法开发了制动压力控制器,在Matlab/Simulink与AMES-im联合仿真环境下验证压力控制效果,结果表明,压力控制效果能够达到主动避撞系统对主动制动控制的要求.
