Abstract
A drive control device is configured to determine a predicted route by predicting a route on which a vehicle drives; sequentially acquire signals detecting a road surface condition from a road surface condition detection sensor that sequentially detects the road surface condition of a road on which the vehicle is driving, and to sequentially estimate a road surface friction coefficient at a plurality of predicted positions on the predicted route; and sequentially plan a speed of the vehicle for driving the predicted route based on the road surface friction coefficient at each predicted position.
Claims7
