Antihydroplaning system for a motor vehicle

Claim 1

An antihydroplaning system for improving wheel adhesion of a motor vehicle, having at least one wheel with a tire, a fuel supply, an engine an da steering booster, in the presence of water on a road surface, comprising: a first sensor for generating first signals indicative of ambient temperature of the vehicle surroundings; a second sensor for generating second signals indicative of chassis vibration; a third sensor for generating third signals indicative of vibration of at least a part of a vehicle body which can be influenced by water splashed from a road surface; a fourth sensor for generating fourth signals indicative of rotational speed and slippage of wheels of said vehicle; electronic means for analyzing and evaluating said first, second, third and fourth signals and for generating output signals; a computer coupled to receive said output signals from said electronic means; and wheel adhesion means for mechanically displacing a water layer on said road surface in front of wheels of said vehicle by means of a mass jet; said wheel adhesion means being controlled over time by said computer in response to a logical analysis of output signals from said electronic means.
