The invention relates to a control system used for self-propelled module transporters, and discloses a multi-vehicle multi-task cooperative control system, which comprises a power control unit, module transport vehicles and a module vehicle control unit, wherein the module transport vehicles are in mechanical hard-wired connection with each other front and back; the power control unit is connected with the first module transport vehicle and is also connected with an electronic control unit ECU of an engine; the module vehicle control unit is connected with a terminal executing mechanism of each module transport vehicle; the power control unit is connected with the module vehicle control unit; and the power control unit acquires an operational command and output data of the electronic control unit ECU of the engine and transmits the operational command and the output data to the module vehicle control unit so as to control the terminal executing mechanism of each module transport vehicle to execute corresponding operation. The multi-vehicle multi-task cooperative control system has the characteristics of adopting the module vehicle control unit to receive the operational command and to control the terminal executing mechanism of each module vehicle to execute the corresponding operation so as to realize the functions of cooperatively controlling steering, running and lifting and the like of each module transporter after splicing.
