摘　　要：针对汽车坡道起步过程中的驻车制动力释放滞后问题,提出了坡道起步过程中气压式电子驻车系统的PID控制方法。首先,在AMEsim中建立了简化的气压式电子驻车系统模型,进行驻车制动释放过程的仿真,并通过实车试验,验证了模型的正确性。接着提出了坡道起步过程中气压式电子驻车制动系统的PID控制方法,根据坡道阻力和发动机驱动力算得目标气压,搭建了气压式电子驻车系统的PID控制模型,并进行了坡道起步过程的仿真和实车试验验证。结果表明,所提出的电子驻车制动系统的PID控制方法能准确控制驻车制动气压值随目标气压的变化,驻车制动释放及时,有效解决了驻车制动力释放滞后的问题,达到良好的坡道起步效果。Aiming at the delay of parking braking force release in hill start process,a PID control scheme for a pneumatic electronic parking brake（ PEPB） system in hill-start process is proposed. Firstly,a simplified model for PEPB system is build with AMEsim and a simulation on hill-start process is conducted with its results and hence the correctness of model built verified by real vehicle tests. Then,a PID control method for PEPB system in hill start process is put forward and the desired air pressure is calculated based on slope resistance and engine driving force. A PID control model for PEPB system is constructed and both simulation and real vehicle verification test are performed. The results show that the PID control scheme proposed for PEPB system can accurately control the air pressure for parking brake changing with desired one and timely release parking brake,so effectively solving the problem of parking braking force release delay and achieving a good result of hill start.
