PROBLEM TO BE SOLVED: To provide a control device for a four-wheel drive vehicle capable of sufficiently deadening vibrations of an electric motor over a wide-range of frequency areas, while absorbing a change with lapse of time of a vibration characteristic with a simple structure. SOLUTION: In this control device for a four-wheel drive vehicle, the one pair of four front and rear drive wheels, WFL and WFR, is driven by an engine 3, and the other pair, WRL and WRR is driven by an electric motor 4. The control device is also provided with a motor driving force setting means 11 which sets a motor driving force TRQ-MOT according to a driving state of a vehicle 2, a motor target number of revolutions calculating means 11 which calculates as a motor target number of revolutions NOBJ the number of revolutions to be obtained if the electric motor 4 revolves in a stable state corresponding to a vehicle speed Vcar, a motor actual number of revolutions detecting means 15 which detects the number of revolutions Nmot of the electric motor 4, and a motor driving force correcting means 11 which corrects the motor driving force TRQ-MOT, based on a deviation DN-CLUCH-R between the motor target number of revolutions NOBJ and the motor actual number of revolutions Nmot. |
