Vehicle control apparatus

Abstract

A control apparatus () for a vehicle provided with a motor/generator (MG; MG) functioning as a drive power source, and a step-variable transmission () which constitutes a part of a power transmitting path between the drive power source and drive wheels () and which is placed in a selected one of a plurality of speed positions with engagement of a selected one or ones of a plurality of coupling devices (CB). The control apparatus includes: a torque control portion () configured to control an output torque (Ti) of the drive power source (MG) during a shifting action of the step-variable transmission () from one of the speed positions to another of the speed positions, on the basis of a required vehicle drive torque (Tidem) corresponding to an operation amount (θacc) of an accelerator pedal, such that a value representing a state of a rotary motion of an input rotary member () of the step-variable transmission coincides with a target value; and a torque limiting portion () configured to limit the required vehicle drive torque to a predetermined lower limit value (Tif) in the process of a shift-up action of the step-variable transmission which is performed by placement of the accelerator pedal in an operated position.
