Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the responsiveness of a drive electric power under the traction control, while preventing the divergence of the drive torque.SOLUTION: A control device of a hybrid vehicle that includes an electric power generator that is driven by an engine and generates electric power for vehicle driving; a driving motor for driving the vehicle; and a battery that can charge and discharge and connects the electric power generator and a driving motor. This control device includes: a torque command value setting means to set a torque command value to the driving motor based on the drive operation of a driver; a traction control means to correct a torque command value when detecting slip of a wheel; a requested generated electric power computing means to compute the requested generated electric power for the electric power generator based on the target driving electric power computed based on the vehicle load or the torque command value. The traction control means does the correction of the torque command value by setting the control parameter considering the response of the engine when the torque command value changes, and using this parameter.
