Abstract
A vehicle control apparatus that inhibits fuel efficiency from being aggravated as a result of ignition timing of the internal combustion engine being retarded. The vehicle control apparatus includes a drive system control unit and an engine control unit. The engine control unit adjusts an amount of intake air based on the demanded torque and adjusts ignition timing so as to compensate for any deviation between torque achievable through an adjustment of the amount of intake air and the demanded torque. The drive system control unit calculates desirable torque to be desirably output to the internal combustion engine for achieving a target operating state of the vehicle, and limits a change rate of the desirable torque by using a predetermined guard value determined from torque adjustment capacity of the internal combustion engine and outputs the desirable torque after the limiting as the demanded torque to the engine control unit.
