Hydroplaning is a very dangerous phenomenon, which occurs more often than one can think. The difference in tire grip between dry and wet surfaces is not more than 15 to 20%, which doesn’t justify the probability increase of losing the vehicle control when it rains or when roads are simply wet. Most accidents are due to the hydroplaning phenomenon, which happens when the tires are lifted by water and their grip goes to zero, as driving on ice. Currently, no countermeasure systems on the market are yet capable of counteracting hydroplaning. ABS, ESP or TCS are still inefficient in overcoming this situation. Many car makers have developed algorithms which can detect hydroplaning conditions but only while they occur: up until now, there isn’t any action that the vehicle itself can automatically take without the risk of potentially dangerous consequences.
