摘要： A control device 6 for a front and rear wheel drive vehicle wherein one of a front wheel pair and a rear wheel pair is driven with an engine 3 and the other one of the front and rear wheel pairs is driven with an electric motor 5 supplied with electric power from an electric storage means is disclosed as including a drive condition detection means for detecting a running condition of the vehicle, a road surface frictional coefficient estimating means 60 for estimating a road surface frictional coefficient, an atmospheric temperature detection means for detecting an atmospheric temperature, a temperature detection means for detecting a temperature of the electric storage means, a motor drive power calculation means 61 for calculating a drive power of the electric motor responsive to the detected running condition and the estimated road surface frictional coefficient, and a control mode changeover means 62, 63 for changing over control modes during calculation of the drive power of the electric motor responsive to the detected atmospheric temperature or/and the temperature of the electric storage means.
