Abstract: A vehicle includes: a motor generator for generating driving power for traveling thereof; an ECU for controlling the motor generator; and an inclination detecting unit for detecting inclination of a road surface. The ECU performs power changing driving in which the vehicle is traveled while switching the motor generator between a first state (high output state) and a second state (low output state). In the first state (high output state), driving power of a first level is generated. In the second state (low output state), the driving power is made smaller than that in the first state. When it is recognized that the vehicle is traveling on an uphill road based on the inclination detected by the inclination detecting unit, ECU sets the driving power in the first state to be larger than that set when the vehicle is traveling on a flat road.

Abstract: An object of the invention is to increase the recovered kinetic energy as much as possible in a regeneration control system for a vehicle that converts the kinetic energy of a wheel into electrical energy while the vehicle is decelerating. To achieve the object, in the invention, the electric energy generated by a generator is decreased at the time when the wheel slips. In consequence, the recovered kinetic energy can be made larger as compared to the case where the electric energy generated by the generator is decreased based on an anticipation of slippage of the wheel made in advance.
