Abstract
Disclosed is a travel control apparatus applied to a vehicle which includes two coupling apparatuses individually changing coupling torques between a drive output part for secondary drive wheels and left and right secondary drive wheel axles and in which the ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. The apparatus generates a yaw moment in a turning direction by using driving force. When a demand of further increasing the yaw moment arises, the control apparatus renders the braking force of the primary drive wheel on the turning locus inner side coincident with a target braking force changing with the travel state of the vehicle and decreases the coupling torque of the coupling apparatus corresponding to the secondary drive wheel on the turning locus outer side. As a result, generation of an anti-spin moment is avoided.
