A total driving force according to an acceleration request of a driver is secured, and deterioration of acceleration performance, such as slowness at the time of starting, is suppressed. When an engine torque is converted into motor torque through a generator, a power distribution ratio α from the engine torque to the motor torque is set. Additionally, as a road surface gradient θ is smaller on an upward slope side, the power distribution ratio α is limited. Specifically, when the road surface gradient θ is more than or equal to a predetermined θ1 on the upward slope side, the power distribution ratio α is set to a predetermined maximum value αMAX. When the road surface gradient θ is less than or equal to θ2, which is smaller than θ1, on the upward slope side, the power distribution ratio α is set to a minimum value αMIN.
