Abstract
A control device for controlling a front wheel drive force and a rear wheel drive force of a vehicle comprises a first controller for controlling a drive force of a main drive wheel and a drive force of an auxiliary drive wheel, the drive force of the main drive wheel being one of the front-wheel drive force and the rear-wheel drive force, and the drive force of the auxiliary drive wheel being another of the front-wheel drive force and the rear-wheel drive force; a second controller for sending to the first controller an auxiliary-drive-wheels-limiting drive force for limiting the drive force of the auxiliary drive wheels in a case that the vehicle is traveling in an unstable state; and a third controller for controlling a motor drive force, which is a source of the drive force of the main drive wheel and the drive force of the auxiliary drive wheel. The third controller reduces the motor drive force on the basis of the auxiliary-drive-wheel-limiting drive force.
