Continental develops an aquaplaning assistant. For this new warning function, sensors should be used already existing assistance systems. For the sensation of the floating, the engineers use dub mirror cameras and acceleration sensors in the tire of the electronic tire information system ETIS.
Although motorists should reduce their speed at wet roads or rain, but should now be warned in addition to aquaplaning. For aquaplaning, if the tires can no longer impest and derive the water on the strain with the help of their profile grooves. As long as the tires are on a water film and thereby lose contact with the strain, the vehicle remains neither steering nor brake. For individual affected tires, the vehicle can break out laterally. Uberreactions surprised driver can add such situations in addition.
Pattern Incompliant displacement
Pictures of the Aune Mirror Cameras for the Surround View function, where the vehicle appears in a virtual top view on the headunit screen, provide the database for detecting the dangerous, incomplete water increment. Even before speed and amount of water come into an unhealthy imbalance, trained algorithms can recognize the typical patterns of the displaced water.
In addition to the camera data, information of sensors should be used directly in the tires. The signal of the accelerometer from the electronic tire information system ETIS ames a typical pattern, according to Continental with water under tire, from which – also by means of algorithms – an aquaplaning danger can be read. Since the already existing sensor of the ETIS system can also recognize the residual profile of the tire, even a secure speed for a particular road network can be calculated. If the system recognizes a danger, the driver is proposed for the relevant speed for the conditions.
Etis can be used as tire prere sensor, offers functions such as load detection and profile depth indication. Due to the transfer of relevant tire information about the stripping condition in driving dynamics control systems such as ESP or Torque Vectoring, it improves the driving behavior through a finefish.
Networking and self-driver in view
Big Data applications and autonomous driving are natural: With C2C and C2X networked cars, the insights from the electron brain as praventive warnings should be passed on to other road users via vehicle-to-vehicle communications and traffic control systems. Continental also attaches value to the determination that assistance systems of this kind should serve for the management and self-control autonomous cars.
A first series use of the technique in the pre-development is conceivable from the point of view of the Continental engineers in a maximum of vehicle generation.
