Abstract
A control apparatus for a vehicle provided with a motor/generator functioning as a drive power source, and a mechanically operated transmission mechanism which constitutes a part of a power transmitting path between the motor/generator and drive wheels, the control apparatus including a motor/generator control portion configured to implement a regenerative torque control of the motor/generator so as to generate a regenerative torque according to a braking operation by an operator of the vehicle in a decelerating run of the vehicle, and a transmission shifting control portion configured to initiate a shift-down action of the mechanically operated transmission mechanism after a rate of change of the regenerative torque has been held within a predetermined range for at least a predetermined length of time, where a determination to implement the shift-down action is made in the process of the regenerative torque control of the motor/generator according to the braking operation.
