Method and device for estimating hydroplaning-occuring vehicle speed and method and device for detecting possibility of occurence of hydroplaning
First Claim
1. A method of estimating a hydroplaning-occurring speed of a vehicle, comprising the steps of:
- (1) detecting an amount of water on a wet road surface on which said vehicle is traveling; and
(2) estimating a speed of said vehicle at and above which a hydroplaning phenomenon can occur, based on the detected amount of water.

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.

6. A device for estimating a hydroplaning-occurring speed of a vehicle having wheels, comprising:
-
road noise-detecting means arranged in the vicinity of at least one of said wheels of said vehicle for detecting road noise generated by said at least one of said wheels; means for extracting data of a parameter indicative of frequency components of said road noise, from said road noise detected by said road noise-detecting means; water amount-detecting means for detecting an amount of water on a road surface on which said vehicle is traveling, based on said data of said parameter indicative of said frequency components of said road noise, by means of a neural network; and vehicle speed-estimating means for estimating a speed of said vehicle at and above which a hydroplaning phenomenon of said vehicle can occur, based on the detected amount of water.
