PROBLEM TO BE SOLVED: To evaluate fluctuation of output torque of an engine, and perform cooperative control between the engine and a motor with considering the fluctuation.SOLUTION: A cooperative control device 1 for a hybrid electric vehicle includes an engine 2 and a motor 3 as driving sources of a vehicle, a control unit 10 for cooperatively controlling the engine and the motor, and actual driving torque detection means 18 for detecting an actual driving torque of the vehicle. If check instruction means transmits a check signal, required torque instruction means changes a required torque to be transmitted to the engine at an arbitrary ratio for an arbitrary time, comparison calculation means compares a vehicle required torque with a vehicle actual driving torque for an arbitrary time, and engine torque correction means corrects a following required torque command value transmitted from the required torque instruction means to the engine according to the comparison result of the comparison calculation means. |
