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.
