Novelty: a warning system destined to protect drivers from wet, cold and negative-temperature road surfaces is disclosed. Constitution: sensors (1,2), a unit for the electronic control of the system 3, signal outputs (5,6), a sound signal source 7 and a visual signal source 8 in the interior of the driver’s cabin 9. Function mode & purpose: the invention is a part of the vehicle’s energetic security equipment warning drivers that their vehicle runs on a negative-temperature road surface or on a road surface being wet by the presence of water or covered by ice, snow or black ice. The central computer of the vehicle 4 gradually reduces the vehicle’s speed; thus, in conditions of reduced adhesion on the road, driving becomes more controllable and road security more enhanced while accidents are avoided in a preventive way. |
