摘要： 电控助力制动器(Ebooster)通过伺服电机控制实现主缸压力调节,可为防抱死制动系统(anti-lock brake system, ABS)提供部分冗余功能。本文中提出了一种用于传统电磁阀式ABS故障时的基于非解耦式Ebooster的3层级联制动防抱死冗余控制架构,包括滑模变结构控制层、压力伺服控制层和电机控制层。基于dSPACE搭建了Ebooster硬件在环试验平台,进行算法测试与验证。结果表明:在ABS失效时,基于Ebooster的制动防抱死冗余控制策略能有效地实现滑移率控制,提高车辆制动稳定性。

Abstract: Electro-booster brake system (Ebooster) achieves master cylinder pressure regulation via servo motor control, and can provide some redundant function for anti-lock brake system (ABS). In this paper, a three-layer cascade anti-lock brake redundant control architecture based on non-decoupled Ebooster is proposed, including sliding mode variable structure control layer, pressure-servo control layer and motor control layer, which will work in case the traditional solenoid valve type of ABS fails. A hardware-in-the-loop test based on dSPACE is carried out to verify the algorithm. The results show that when the faults in ABS occur, the Ebooster-based anti-lock brake redundant control strategy can effectively fulfill slip-rate control, enhancing the braking stability of vehicle.
