The invention relates to a multi-motor coupling electric drive control system for a vehicle, and relates to the technical field of mechatronics drive control systems. The output end of the gear box is connected with a differential mechanism, the input end of the gear box is provided with four sets of motors, the four sets of motors are coupled in parallel, a fixed shaft type electromechanical coupling structure used for torque transmission is arranged in the gear box, and an oil cooling circulation structure is arranged on the gear box; the oil cooling circulation structure is used for cooling the gear box and the motor so as to optimize the working conditions of the gear box and the motor; and two sets of controllers are further included, and the motor is electrically connected with the controllers. The power system is mainly applied to commercial vehicle heavy trucks, mine trucks, engineering machinery and other subdivided field markets, serves as a solution for solving the problems that a high-power and high-efficiency power system lacks and the like, particularly meets the requirements of special working condition use scenes of low-speed heavy-load and high-frequency short-distance transportation, and has the advantages of optimizing the working condition of an engine or a motor and improving the working efficiency. Oil consumption and emission are reduced, and good power performance is guaranteed.
