Abstract

A vehicle control apparatus includes: a transmission shifting control portion configured to implement a shifting action of a step-variable transmission, by controlling a releasing action of a releasing coupling device and an engaging action of an engaging coupling device; a torque control portion configured, during the shifting action of the step-variable transmission, to implement a feedback control to control an input torque inputted to the step-variable transmission, 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 dependent on a degree of progress of the shifting action; and a backup control portion configured, when it is determined that the drive wheels are slipped, to inhibit the feedback control, and to compensate a transmitted torque to be transmitted through an initiative coupling device, such that the shifting action is facilitated by compensation of the transmitted torque.
