Abstract
When a rear wheel total drive force is smaller than a rear wheel drive force difference and the rear wheel drive force difference cannot be realized by setting a left-right distribution of the rear wheel total drive force, an inside wheel target drive force is set unconditionally to a minimum initial drive force required to prevent a three-wheel drive state and an outside wheel target drive force is set to a value equal to the sum of the initial drive force and the rear wheel drive force difference, which is a value with which the rear wheel drive force difference can be realized while the inside wheel target drive force is set to the initial drive force. In this way, a drive force distribution control apparatus gives priority to realizing the rear wheel drive force difference and emphasizes achieving a target behavior over achieving a four-wheel drive performance.
