摘　　要：为解决汽车智能驾驶制动、无人驾驶制动或自动紧急制动(AEB:Autonomous Emergency Braking)问题,提出电子真空助力器制动控制系统及方法。控制器系统控制电子真空助力器的电磁阀,实现主动增压和被动增压,实现汽车主动制动和被动制动,同时增加电磁阀温度模型控制。实验结果表明,该设计解决了无人驾驶时,电子真空助力器长时间刹车制动导致驱动芯片发热造成驱动不足引起的制动力不足的问题,可应用于无人驾驶、自动紧急制动和自适应巡航。An electronic vacuum booster braking control system and method are proposed for solving the problems of intelligent driving braking, driverless braking or automatic emergency braking. The controller system controls the solenoid valve of the electronic vacuum booster to realize the active and passive pressurization, and realize the active braking and passive braking of the vehicle. The temperature model is used to solve the problem of insufficient braking force caused by the heating of the drive chip and the long-time braking. It provides a control principle and method for controlling electronic vacuum booster.
