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 the drive force of auxiliary drive wheels wherein the drive force of the main drive wheel is one of a front-wheel drive force and a 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 in a case that the vehicle is traveling in an unstable state. The second controller has a calculation unit for calculating the auxiliary-drive-wheel-limiting drive force on the basis of a vehicle instability parameter. The first controller increases the drive force of the main drive wheel by causing the drive force of the auxiliary drive wheel to match the auxiliary-drive-wheel-limiting drive force.
