Patent ID: 8744710

Claim:
A control device for controlling a front wheel drive force and a rear wheel drive force of a vehicle that includes a transmission, the control device comprising: first control means 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; and second control means for detecting whether a speed-change ratio of the transmission has changed, wherein the first control means increases the drive force of the auxiliary drive wheel and reduces the drive force of the main drive wheel when the second control means has detected that the speed-change ratio of the transmission has increased, and the first control means increases the drive force of the auxiliary drive wheel and reduces the drive force of the main drive wheel when the second control means has detected that the speed-change ratio of the transmission has decreased.
