The invention discloses a braking failure control method, device and system for a distributed driving vehicle, and the method comprises the steps: determining the required braking force of each wheel according to the braking failure form and braking grade of the distributed driving vehicle; according to the motor rotating speed, the vehicle speed, the braking strength and the charge state, the regenerative braking force of each wheel is determined; under the condition that the required braking force is larger than the regenerative braking force, braking failure control is conducted according to the required braking force, the regenerative braking force and the maximum mechanical braking force of each wheel; and under the condition that the required braking force is smaller than or equal to the regenerative braking force, braking failure control is conducted according to the required braking force and the regenerative braking force. According to the technical scheme provided by the invention, brake failure control can be performed on the distributed driving automobile carrying the EMB system, and the safety and the driving stability of the automobile are improved.
