The autonomous car must guarantee safety in all road condition included driving on a wet road. The aquaplaning (or hydroplaning) it's a phenomenon born with the car, and never solved with an active safety system. Currently, no countermeasure systems on the market are yet capable of contrasting the hydroplaning. ABS, ESP or TCS are still inefficient in overcoming this situation. The data available confirm the higher percentage of accident, injury and died are caused by wet road condition. The aquaplaning appears when the water on the road is too much and the tire starts to lift causing the instantaneous loss of control. That phenomenon occurs in the normal vehicle, with the responsibility of the driver, but in an autonomous vehicle (example Lev 5), the responsibility for the safety depends by the car and the reduction of the speed it's not a solution. The anti aquaplaning active safety system, proposed in this article it's the second release, able to understand, without any new sensor if the car it's subject aquaplaning. When the software detects an event, the hydraulic system designed to have a very short reaction time, make an intelligent injection of water in front of the tyre restoring the adherence of an autonomous vehicle (but also a standard one) in few milliseconds. Will also demonstrate how the system could be integrated with the electronics tire (tested for the first time in the automotive history) and also the strong contribution that the system can give with the Adas sensors and 5G smart city technology.
