To protect a tire from abnormal deformation by considering temperature of the tire during vehicular traveling.

When there is a possibility of abnormal deformation in the tire, vehicular braking is automatically carried out (S71), and then, if the tire temperature T is a target temperature Tt or more, the automatic braking of the vehicle is stopped (S75 to S78). By this, deterioration due to vehicular speed reduction is suppressed of a cooling effect of the tire by traveling wind which is a flow of air caused in a periphery of the tire by vehicular traveling. Then, if the tire temperature T is the target temperature Tt or more, vehicular acceleration is automatically carried out (S79 to S81), and by this, the cooling effect of the tire by the traveling wind is actively increased.
