The invention discloses a proportional valve type double-loop braking device and a control method thereof, and belongs to the technical field of vehicle braking. The proportional valve type double-loop brake device comprises a brake controller, a double-loop proportional valve and a brake valve. The brake controller is in communication connection with the double-loop proportional valve, the brake valve and the unmanned controller. The brake controller is used for controlling the duty ratio of the power supply voltage of the double-loop proportional valve and monitoring whether the working state of the double-loop proportional valve is normal or not; the double-loop proportional valve is used for providing a matched brake-by-wire execution command for the vehicle. The proportional valve type double-loop brake device is high in reliability, few in parts, small in occupied vehicle space, simple in arrangement and capable of being better matched with a novel drive-by-wire brake system and a core execution component which are operated in an unmanned mode.
