Abstract

A control apparatus is provided for a vehicle that includes (i) an engine serving as a drive power source, (ii) a motor/generator serving as the drive power source and (iii) a mechanically-operated transmission mechanism that constitutes a part of a power transmitting path between the drive power source and drive wheels of the vehicle. The control apparatus includes a shift control portion is configured, when an input torque inputted to the mechanically-operated transmission mechanism is to be controlled in process of a coasting shift-down action executed in the mechanically-operated transmission mechanism, to determine an upper limit value of the input torque inputted to the mechanically-operated transmission mechanism in the process of the coasting shift-down action, such that the determined upper limit value is lower during operation of the engine than during stop of the engine.
