The invention relates to a redundant braking system based on vehicle automatic driving and a braking method thereof. The system comprises a main controller, a first controller, a second controller and a third controller, the main controller is connected with the first controller, the second controller and the third controller, the first controller is used for controlling the hydraulic mechanism and the third controller according to a braking request sent by the main controller so as to brake the vehicle; the second controller and the third controller respond to the braking request of the main controller respectively, and braking of the vehicle is achieved by controlling a parking braking mechanism and/or a driving motor of the vehicle. On the basis that a braking backup unit is not added, the electronic parking and the driving motor are adopted to meet the braking redundancy requirement, the parking braking system serves as a part of service braking redundancy, multiple braking redundancy is formed, the service braking redundancy and the parking braking redundancy are met at the same time, and the utilization rate of the braking system is increased.
本发明涉及一种基于车辆自动驾驶的冗余制动系统及其制动方法,其系统包括:包括主控制器、第一控制器、第二控制器和第三控制器,所述主控制器分别与第一控制器、第二控制器和第三控制器连接,所述第一控制器,用于根据主控制器发出的制动请求,控制液压机构和第三控制器,以实现车辆的制动;所述第二控制器和第三控制器,分别响应于主控制器的制动请求,通过控制驻车制动机构和/或车辆的驱动电机,实现车辆的制动。本发明在不增加制动备份单元的基础上,采用电子驻车和驱动电机实现制动冗余需求,将驻车制动系统作为行车制动冗余的一部分,形成多重的制动冗余,同时满足行车制动冗余和驻车制动冗余,提高制动系统的利用率。
