<p>The method involves extracting a portion relative to passage of a strain gauge in an apparent contact patch of a tire tread of a tire on the wet ground, from a signal corresponding to characteristic quantity measurement. An instantaneous value connected to length of an indirect contact area of the patch, and another value connected to a hydroplaning phenomenon intensity in the area relative to rest of the patch are deduced from the portion. Water height is estimated from calculation taking into account the former value. The intensity is estimated from the height and the latter value. An independent claim is also included for a device for detecting and estimating hydroplaning phenomenon intensity of a tire of a vehicle moving on wet ground of a roadway.</p> |
