The invention relates to a redundant brake-by-wire system and a vehicle. The system comprises a brake controller used for generating at least one of a first front axle brake signal and a first rear axle brake signal; the front axle valve is used for realizing front axle electric control braking according to the first front axle braking signal; the rear axle valve is used for realizing rear axle electric control braking according to the first rear axle braking signal; the vehicle control unit is in communication connection with the brake controller and is used for generating at least one of a second front axle brake signal and a second rear axle brake signal under the condition that the brake controller fails; and the backup valve is used for controlling the mechanical braking function of the front axle valve according to the second front axle braking signal so as to realize front axle braking and controlling the mechanical braking function of the rear axle valve according to the second rear axle braking signal so as to realize rear axle braking. By the adoption of the system, the requirement for automatic driving and driver-free control can be met under the condition that any single-point failure occurs in the system.

    本申请涉及一种冗余线控制动系统及车辆。所述系统包括:制动控制器,用于生成第一前桥制动信号和第一后桥制动信号中至少一种;前桥阀,用于根据所述第一前桥制动信号实现前桥电控制动;后桥阀,用于根据所述第一后桥制动信号实现后桥电控制动;整车控制器,与所述制动控制器通信连接,用于在所述制动控制器失效的情况下,生成第二前桥制动信号和第二后桥制动信号中至少一种;及备份阀,用于根据所述第二前桥制动信号控制所述前桥阀的机械制动功能以实现前桥制动,以及根据所述第二后桥制动信号控制所述后桥阀的机械制动功能以实现后桥制动。采用本系统能够实现在系统内发生任何单点失效情况下都可以实现自动驾驶无驾驶员控制要求。
