The invention relates to the technical field of electronic parking, in particular to a redundant electronic parking system and a control method thereof. The redundant electronic parking system comprises M control units, M selectors, an electronic parking switch device and an electronic parking device; M is an integer greater than or equal to 2; the M control units are connected with the M selectors in a one-to-one correspondence manner; each control unit in the M control units is connected with the electronic parking device through a corresponding selector; the electronic parking switch device is connected with each control unit; the M control units are connected with one another; the fault states of the M control units are monitored through communication among the M control units; and therefore, when a fault control unit exists in the M control units, the electronic parking device can be controlled based on the remaining working control units. Therefore, when the electric control units of the braking system fail, full-load parking braking of the vehicle on the 8% ramp can still be achieved.

    本发明涉及电子驻车技术领域,特别涉及一种冗余的电子驻车系统及其控制方法。该冗余的电子驻车系统包括M个控制单元、M个选择器、电子驻车开关装置和电子驻车装置;该M为大于等于2的整数;该M个控制单元与该M个选择器一一对应连接;该M个控制单元中的每个控制单元通过对应的选择器与该电子驻车装置连接;该电子驻车开关装置与该每个控制单元连接;该M个控制单元之间互连;通过该M个控制单元之间的通信实现对该M个控制单元的故障状态进行监控;从而使得当M个控制单元中存在故障控制单元时,可以基于剩余的可工作的控制单元对电子驻车装置进行控制;从而使得当制动系统电控单元失效时,仍可实现车辆在8%坡道上实现满载驻车制动。
