Abstract

A vehicle control apparatus for controlling a four-wheel-drive automotive vehicle of a type which comprises a first drive power source for driving one of a pair of front wheels and a pair of rear wheels, and a second drive power source for driving the other of the pairs of front and rear wheels, wherein an operator's desired value of a vehicle drive force for driving the automotive vehicle is obtained on the basis of an amount of operation of a manually operated vehicle accelerating member and a running speed of the vehicle, and a front drive force for driving the pair of front wheels and a rear drive force for driving the pair of rear wheels are controlled on the basis of a static and a dynamic state of the vehicle such that a sum of the front drive force and the rear drive force is equal to the obtained operator's desired value of the vehicle drive force.
