The embodiment of the invention provides a braking control method and system for a distributed braking system, the method and system are applied to a vehicle, a braking domain controller is in communication connection with a wheel side controller through a high-speed bus, and the wheel side controller is in communication connection with a wheel speed sensor through a signal line; when a high-speed bus communication fault occurs, the brake domain controller enters a fault state, the wheel edge controller applies target clamping force to the wheels of the vehicle through the electronic calipers, the electronic calipers are controlled according to wheel speed signals collected by the wheel speed sensor, and wheel braking is achieved. Safety braking of the vehicle is achieved through the wheel edge controller, the safety and robustness of the distributed braking system are improved, the wheels are controlled through the target clamping force to achieve safety braking at the minimum deceleration, it is guaranteed that the vehicle can still achieve safety braking even if high-speed bus communication breaks down and cannot be controlled through the braking domain controller, and the safety of the vehicle is improved. And the security and the system robustness are improved.
本申请实施例提供了一种分布式制动系统的制动控制方法及系统,应用于车辆,制动域控制器与轮边控制器通过高速总线通讯连接,轮边控制器与轮速传感器通过信号线通讯连接;在高速总线通讯故障时,制动域控制器进入故障状态,轮边控制器通过电子卡钳向车辆的车轮施加目标夹紧力,并根据轮速传感器采集到的轮速信号控制电子卡钳,实现车轮制动。通过轮边控制器实现车辆的安全制动,提高分布式制动系统的安全性和鲁棒性,通过目标夹紧力控制车轮以最低减速度实现安全制动,保证车辆即使在高速总线通讯故障,无法通过制动域控制器控制时,依然可以实现安全制动,提高安全性和系统鲁棒性。
