The invention discloses a vehicle redundant braking system, a control method and a vehicle. The vehicle redundant brake system comprises a control module, a main brake module, a redundant brake module, a wheel cylinder module and a brake fluid conveying pipeline, wherein the main brake module and the redundant brake module are respectively connected with the wheel cylinder module through the brake fluid conveying pipeline; the redundant braking module comprises a redundant pressure providing unit and an energy accumulator; the control module is used for controlling the redundant pressure providing unit to provide first driving force for the energy accumulator under the condition that the main braking module is abnormal and a braking request is received, and controlling the redundant pressure providing unit to provide second driving force under the condition that the pressure in the energy accumulator does not meet a preset pressure value. According to the system, the energy accumulator can be pressurized and stored before redundant braking, the redundant pressure providing unit is assisted to build pressure quickly, the pressure building speed of the redundant braking module is increased, and the safety of vehicle braking is improved.
