The invention relates to the technical field of vehicles, in particular to a redundant electronic parking brake system, a control method and a vehicle. Comprising a first electronic parking braking module used for receiving a first parking instruction and conducting parking braking on a first wheel set of a vehicle according to the first parking instruction; the second electronic parking braking module is used for receiving a second parking instruction and carrying out parking braking on a second wheel group of the vehicle according to the second parking instruction; the whole vehicle dynamic domain manager is used for sending a first parking instruction according to the parking braking request; and the braking control module is used for sending a second parking instruction according to the parking braking request. The EPB brake caliper is divided into two parts, and then the brake caliper is independently controlled by the VDDM and the BBM, so that the redundancy design is realized under the condition that the original working state is not changed. After a P-gear lock mechanism in the transmission is reduced, only a controller power supply and signal transmission path is adjusted, the number of whole vehicle parts is reduced, light weight is achieved, and cost is greatly reduced.
本申请涉及车辆技术领域,尤其涉及一种冗余电子驻车制动系统、控制方法及车辆。包括:第一电子驻车制动模块,用于接收第一驻车指令,并根据第一驻车指令对车辆的第一车轮组进行驻车制动;第二电子驻车制动模块,用于接收第二驻车指令,并根据第二驻车指令用于对车辆的第二车轮组进行驻车制动;整车动态域管理器,用于根据驻车制动请求发送第一驻车指令;制动控制模块,用于根据驻车制动请求发送第二驻车指令。通过将EPB制动卡钳分成两部分,再由VDDM和BBM单独和控制,在未改变原工作状态的情况下,实现了冗余设计。减少了变速器内P档锁机构后,仅调整了控制器电源供电和信号传输路径,减少整车部件实现了轻量化,并且使成本大幅度降低。
