Antihydroplaning system for a motor vehicle
First Claim
Patent Images
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.

Abstract
This invention relates to a vehicle comprising an antihydroplaning system, particularly for improving the wheel adhesion despite the presence of a sheet of water on the road. Output signals from sensors for detecting body and chassis vibrations, ambient temperature and other parameters are analyzed to determine when hydroplaning is occurring or about to occur, and to activate antihydroplaning measures.
