Abstract
A vehicle includes a first detector detecting first information related to a condition of a first road surface; a second detector contactlessly detecting second information related to a condition of a second road surface; and a controller controlling a driving force of the vehicle using a friction coefficient estimated based on the first and/or second information. A processor(s) of the controller execute(s) a process including: determining whether the conditions are of a same type based on the first and second information; when the conditions are of different types, controlling the driving force using a friction coefficient estimated based on the second information as a friction coefficient of the second road surface; and based on determining that the conditions are of the same type, controlling the driving force using a friction coefficient estimated based on the first information as the road surface friction coefficient of the second road surface.
