The invention provides a braking system and a braking method. The system comprises a master controller, a slave controller, a first actuator corresponding to the master controller and a second actuator corresponding to the slave controller. The master controller can monitor the working states of a power system controller, a steering system controller, a parking system controller and the slave controller; and when any one or more of the power system controller, the steering system controller and the parking system controller are in an error state and the slave controller is in a normal state, afirst braking instruction is sent to the slave controller. The slave controller can monitor the working state of the master controller, and controls the second actuator to execute the braking operation based on the first braking instruction when the master controller is in a normal state. Based on the redundant controller design, vehicle key electronic device monitoring and mutual monitoring of the master controller and the slave controller can be achieved, so safety risks possibly caused by electronic and electrical faults during unmanned parking can be coped with.
本发明提供了一种制动系统及制动方法,该系统包括主控制器、从控制器、主控制器对应的第一执行器以及从控制器对应的第二执行器。主控制器可以监控动力系统控制器、转向系统控制器、泊车系统控制器和从控制器的工作状态,并在动力系统控制器、转向系统控制器、泊车系统控制器中任意一个或多个控制器处于错误状态而从控制器处于正常状态时,向从控制器发送第一制动指令。从控制器则可以监控主控制器的工作状态,并在主控制器处于正常状态时,基于第一制动指令控制第二执行器执行制动操作。基于本发明的冗余控制器设计,可以实现车辆关键电子装置监控以及主从控制器的相互监控,从而应对无人泊车可能出现的因电子电气故障所造成的安全风险。
