The invention discloses a braking system for redundant backup of an EHB whole vehicle large motor of an unmanned vehicle. The electronic hydraulic brake system comprises an integrated electronic hydraulic brake system module and a motor redundancy backup module, a pedal-free structure is adopted, the integrated electronic hydraulic brake system module is connected with wheel calipers through oil pipes, and the motor redundancy backup module is connected with four wheels; in the electronic hydraulic brake system module, an output shaft of a conventional brake motor is connected with a plunger pump, the plunger pump is communicated with a liquid storage tank, a plurality of oil way elements are further arranged in a valve body, and the oil way elements and the conventional brake motor are connected with a controller. In the motor redundancy backup module, a battery is electrically connected with a redundancy backup motor, and a transmission shaft of the redundancy backup motor is connected with four wheels through a transmission mechanism. The device is small in size, simple in structure, low in cost, convenient to install, applicable to unmanned vehicles and capable of being completely driven in an unmanned mode.
