Abstract
An object of the present invention is to suppress reverse of a vehicle on an up-hill road against an intention of a driver. A drive device for a vehicle according to the present invention includes: an estimator for estimating whether or not reverse of the vehicle occurs on an up-hill road; a rotating electric machine for generating electric power by rotation of a drive wheel in the vehicle when the vehicle reverses; a capacitor for electrically charging the electric power generated by the rotating electric machine; and a battery connected in parallel to the capacitor, wherein the estimator estimates that the reverse of the vehicle occurs when a current traveling road is an up-hill road and a vehicular speed is smaller than a threshold whereas the electric power of the capacitor is electrically discharged to the battery when the reverse of the vehicle is estimated and the amount of electric energy of the capacitor is greater than a certain threshold.
