Abstract
The hydroplaning-occurring speed of a vehicle is estimated by detecting an amount of water on a wet road surface on which the vehicle is traveling, and estimating a speed of the vehicle at and above which a hydroplaning phenomenon can occur, based on the detected amount of water. The possibility of occurrence of a hydroplaning phenomenon of a vehicle is detected by detecting an amount of water on a wet road surface on which the vehicle is traveling, detecting the speed of the vehicle, and determining whether there is a possibility that a hydroplaning phenomenon can occur, based on the detected amount of water and the detected speed of the vehicle.
