The redundant drive-by-wire brake system comprises an automatic driving controller, a main line control brake module, a redundant drive-by-wire brake module, an ABS anti-lock brake adjusting module and a brake, and the main line control brake module comprises a first oil storage pot, a brake main cylinder, a first motor, a speed reduction and main cylinder piston pushing mechanism and a main line control brake controller; the redundant drive-by-wire brake module comprises a second oil storage pot, a micro hydraulic pump, a second motor, a first normally-open solenoid valve, a first normally-closed solenoid valve, a second normally-closed solenoid valve, a second normally-open solenoid valve, a third normally-open solenoid valve, a hydraulic pressure sensor and a redundant drive-by-wire brake controller. The ABS anti-lock braking adjusting module is connected with the main line control braking module and the redundancy line control braking module through braking pipelines, the ABS anti-lock braking adjusting module is connected with the brake through a braking pipeline, and the automatic driving controller is connected with the main line control braking controller and the redundancy line control braking controller through a CAN bus. The main line control brake controller is connected with the redundant line control brake controller through a CAN bus.
