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.
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 said pairs of front and rear wheels, said vehicle control apparatus being operable to control a front drive force for driving said pair of front wheels and a rear drive force for driving said pair of rear wheels, depending upon a static and a dynamic state of the vehicle such that a sum of said front drive force and said rear drive force is equal to an operator's desired value of a vehicle drive force for driving said automotive vehicle, which operator's desired value is obtained on the basis of an amount of operation of a manually operated vehicle accelerating member and a running speed of the vehicle.
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 said pair of front and rear wheels, said vehicle control apparatus being operable to drive said automotive vehicle in a four-wheel driving mode in which said pairs of front and rear wheels are driven by said first and second drive power sources, when said automotive vehicle is placed in any one of a starting state in which the vehicle is being started, an accelerating state in which the vehicle is being accelerated, and a low-μ running state in which the vehicle is running on a road surface whose friction coefficient is lower than a predetermined threshold, said vehicle control apparatus being operable to drive said automotive vehicle in a two-wheel driving state in which one of said pairs of front and rear wheels are driven, when the vehicle is not placed in any one of said starting state, accelerating state and said low-μ running state.
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 said pairs of front and rear wheels, said vehicle control apparatus comprising:
