METHOD FOR ESTIMATING THE WATER LEVEL ON A ROADWAY WHEN A TYRE IS RUNNING

A method for estimating a water height on a roadway where a tire of a vehicle is running, the mounted assembly being placed in a wheel arch of the vehicle, comprises the following steps: fixing a sensor onto the vehicle; obtaining a frequency signal from the sensor corresponding to the running of th...

Zusammenfassung:	A method for estimating a water height on a roadway where a tire of a vehicle is running, the mounted assembly being placed in a wheel arch of the vehicle, comprises the following steps: fixing a sensor onto the vehicle; obtaining a frequency signal from the sensor corresponding to the running of the vehicle at speed V on the roadway covered with a water height heau; isolating a part of the frequency signal, bounded by two strictly increasing frequencies, which is sensitive to the height heau; determining an energy vector linked to the part of the frequency signal; and obtaining the water height on the roadway using a function taking account of the energy vector and the speed V of the vehicle. The sensor is a microphone, and the part of the frequency signal extends at least partly beyond 4 kHz.
