Aquaplaning Warning System from Continental
Continental is developing an automatic system to warn the risk of aquaplaning using networked cameras and tyre sensors with intelligent software. With this, drivers will be warned in time and can better adjust their speed in advance.
Aquaplaning or hydroplaning by the tyres occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.
According to Continental, an initial production of the technology is conceivable in the next generation of vehicles. The hardware and software for the system are being developed in Frankfurt, Hanover and Toulouse.
“Even with the best tyres, sudden aquaplaning is always a frightening moment and can mean the danger of an accident. We are developing a high-performance technology based on sensor information and software that detects a potential risk of aquaplaning and warns the driver in time,” said Frank Jourdan, member of the Continental Executive Board and head of the Chassis & Safety division.
As aquaplaning depends on the tread depth of the tyres, the depth of the water on the road and the driving speed, Continental recommends renewing summer tyres with a remaining tread of three millimetres.
In addition to the camera data, Continental also plans to use information from the tyres to identify the risk of aquaplaning. Here, the sensor signals will be analyzed directly in the tyres. Signals from the Electronic Tyre Information Systems (eTIS) warn about an imminent risk of aquaplaning.
In future, it will be possible to evaluate all sensor data in a central vehicle computer for the aquaplaning warning system. If the system detects a danger at the current speed, the driver will be notified of a safe speed, says Continental.
