摘要:
A brake vacuum boosting control system for a motor vehicle comprises a brake actuating unit for actuating the vehicle to be braked, a sensing unit (11) for sensing a braking signal of the vehicle, a main ECU (12) which receives the braking signal from the sensing unit (11), and a main control circuit connected to the main ECU (12) and the brake actuating unit respectively, and the main ECU (12) outputs a control signal to the brake actuating unit through the main control circuit after receiving the braking signal to brake the vehicle. The control system further comprises an auxiliary ECU (17) connected with the main ECU (12), and an auxiliary control circuit connected with the auxiliary ECU (17), the sensing unit (11), and the brake actuating unit respectively. The auxiliary ECU (17) functions to receive the braking signal and outputs the control signal to the brake actuating unit through the auxiliary control circuit to brake the vehicle when at least one of the main ECU (12) and the main control circuit is in an abnormal state. A control method thereof is also provided. Based on the control system and the control method thereof, the brake boosting can be effectively controlled and safety of a driver can be protected maximally in an abnormal condition such as the main ECU (12) being disabled.
摘要(中):
一种用于机动车辆的制动器真空升压控制系统,包括用于致动要制动的车辆的制动器致动单元,用于感测车辆的制动信号的感测单元(11),主ECU(12),其从 感测单元(11)和分别连接到主ECU(12)和制动器致动单元的主控制电路,并且主ECU(12)在接收到之后通过主控制电路向制动致动单元输出控制信号 制动信号来制动车辆。 控制系统还包括与主ECU(12)连接的辅助ECU(17)和分别与辅助ECU(17),感测单元(11)和制动致动单元连接的辅助控制电路。 辅助ECU(17)用于接收制动信号,并且通过辅助控制电路将控制信号输出到制动执行单元,以在主ECU(12)和主控制电路中的至少一个处于 异常状态 还提供了其控制方法。 基于控制系统及其控制方法,能够有效地控制制动助力,并且能够在诸如主ECU(12)被禁用的异常状态下最大限度地保护驾驶员的安全性。
