“…The three-zone description is useful because it helps: -To understand why friction on a wet road, which is generated only in the mixedcontact zone, is lower than on a dry road; -To study the onset of hydroplaning where the tire is entirely supported by the water film. Many researches have been dedicated to this dangerous situation [24][25][26][27] where, locally, a tread element entering the contact area does not have enough time to go through the water film-sinkage-to be in contact with the road surface asperities. One can see the importance of the water depth, which defines the time to sinkage, and the vehicle speed, which defines the time of traversal that a tread element needs to go through the contact area.…”

This paper presents an evaluation of a system aiming at estimating water depths on a road surface. Using accelerometers, the system records the vibrations of a wheel arch liner due to impacts of water droplets. The system setup, including the location of the accelerometers on a wheel arch and the data acquisition, is described. Tests were performed with a passenger car on various road surfaces and at different vehicle speeds and water depths. Signals recorded by the accelerometers are filtered and processed. The link between the acceleration amplitude, the water depth, and the vehicle speed is consistent with results from previous studies. The effect of the surface texture is less obvious and needs further investigations. A mathematical model has been developed to relate the acceleration amplitude to the water depth. The potential application of the developed system to on-board evaluation of pavement wetness, and consequently the pavement skid resistance, is discussed. Perspectives for driver assistance, or more generally, for autonomous driving to improve traffic safety, are also highlighted.
