To reduce risk of feeling dissatisfaction of not satisfying a driving request by a driver, when both turning assisting control and traction control on the whole control object wheels are simultaneously performed.
This travel control device of a vehicle performs the turning assisting control for controlling longitudinal force of the wheels so that longitudinal force of a turning inner wheel reduces more than a turning outer wheel, and the traction control for reducing a driving slip by reducing the longitudinal force of the wheels when the driving slip of the wheels is excessive. In a state of reducing the longitudinal force of the whole control object wheels by the traction control when performing the turning assisting control, a reduction quantity of the longitudinal force of the turning inner wheel by the turning assisting control is reduced, or reduction in the longitudinal force of the turning inner wheel by the turning assisting control is stopped. Thus, driving force of the whole vehicle is increased by a quantity of reducing the reduction quantity of the longitudinal force of the turning inner wheel.
