Abstract
A control device for controlling a front wheel drive force and a rear wheel drive force of a vehicle includes a first controller for controlling a drive force of main drive wheels and a drive force of auxiliary drive wheels, wherein the drive force of the main drive wheel is one of the front-wheel drive force and the rear-wheel drive force, and the drive force of the auxiliary drive wheel is another of the front-wheel drive force and the rear-wheel drive force, and 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. The second controller has a preparatory unit for preparing reference drive force, a first limiting unit for limiting a reduction in the auxiliary-drive-wheels-limiting drive force, and a second limiting unit for limiting an increase in the auxiliary-drive-wheels-limiting drive force.
