The invention discloses a multi-motor coordination controller for a distributed driving electric automobile. The multi-motor coordination controller designs three corresponding driving modes of economy, stability, and dynamic property for different driving structures, and a fault-tolerant mode conforming to characteristics of the driving structures; the driving coordination controller is connected with a whole automobile controller and a plurality of motor controllers through a CAN bus; a layered structure of the whole automobile controller, the driving coordination controller and the motor controllers is adopted; the driving coordination controller is arranged between the whole automobile controller on the upper layer and the motor controllers on the lower layer, is responsible for receiving driving requirement signals, steering requirement signals, configuration form signals and functional mode signals of the whole automobile controller, considers manufacturing and type selection difference of the motors for preset at the same time, and dynamically adjusts driving torques of the motors to meet whole automobile driving and steering requirements under different functional modes. The multi-motor coordination controller effectively improves the safety and the controllability of the distributed driving electric automobile, and deepens industrial division.
