A vehicle control device which can substantially eliminate or shorten a period when vehicle speed exceeds a lowered speed limit when a vehicle goes into a road where a speed limit lower than before then during running of the vehicle should be provided. A speed control decreases vehicle speed so that the vehicle speed approaches the next speed limit from a time point when it is judged that a position of the own-vehicle is at a predetermined position in front of a transition point which is a point where the next speed limit starts to be applied, in a case where a specified condition that the next speed limit is lower than the present speed limit is satisfied.

A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the carcass. The temperature of the track may also be used to alert an operator of a track temperature issue or request that the operator reduce the speed of the vehicle.
