Car Fule

As a motorist, you have most likely already driven under a downpour, where you had to drastically reduce your pace.

When the road is wet, a dangerous phenomenon can occur if you are not careful: l’aquaplaning. It is a danger that occurs when you are driving too fast and at the same time there is too much water on the road. In this case, the tires cannot drain water quickly enough and begin to lose grip and «Faster» above ground.

An innovative system to predict aquaplaning?

To counter this phenomenon, we can already start with moderate your pace. But it can be complicated at times predict the speed to adopt.

In order to help and assist drivers, the Italian firm EasyRain created a high-tech solution. The idea: anticipate and report the problem of aquaplaning in advance. This system is called Digital Aquaplaning Information (DAI) and uses the 5G network to anticipate risks on the road.

Predictive operation

The DAI is a predictive virtual sensor, endowed specific algorithms which process the information available on the dynamics of the vehicle. The system calculates the longitudinal force, the lateral force as well as the tire slip. One of its functions is in particular the automatic and instantaneous activation of the complementary system which is called AIS. The latter is a system capable of restoring the grip of the tire thanks to a controlled water jet injected upstream of the front wheels.

With the system, corrections can be calculated and suggested to the driver, and even directly implemented in the vehicle configuration to improve driving safety in wet conditions.

There are several levels of DAI signaling, which are directly visible on the dashboard:

• Warning ! Wet road: This is the first level of alert. In this case, the driver is in a potentially dangerous situation on wet roads and the system signals that care must be taken.
• Danger ! Wet road: This is the second level of alert, and according to the analysis of the sensors, it activates when the water layer on the road surface is already heavy. In this situation, the high speed of the car can cause aquaplaning and the driver can quickly lose control. The latter must be extra vigilant and slow down quickly.
• Alert! Aquaplaning: This is the highest level of danger, the vehicle is aquaplaning. Once you get to that level, the tires can’t shed water quickly enough and there is no more grip. In this scenario, the DAI system instantly activates AIS to help reduce wheel slip.

For the moment, no information regarding the price of this DAI. But it is true that additional driving assistance is always welcome …
