  • the object of the invention is therefore to provide a method of the type mentioned above, with the early detection of the occurrence of a risk of aquaplaning is possible and at the same time preventive as possible the occurrence or risk of aquaplaning is prevented or reduced and: the aforementioned disadvantages are avoided ,
  • At least one sensor device is provided for determining a wet roadway
  • the traffic-segment-related information according to method step a) is preferably provided by traffic sign recognition of a traffic sign indicating aquaplaning, and / or by means of a telematics function.
  • the traffic sign recognition usually takes place by means of a camera, the. picking up the surroundings in front of the vehicle and supplying corresponding image data to an on-board computer, which analyzes and classifies the image data by means of an algorithm, in order to identify a traffic sign from this.
  • the stretch section related information regarding the presence of the danger of aquaplaning may be provided by means of a telematics function.
  • a telematics function This means, for example, that vehicles communicate with one another on the road and via a set-up infrastructure, such as V2V (Vehicle to Vehicles) or C2C (Car to Car), and data that is present in the vehicle, in particular data indicating aquaplaning capture and exchange, if necessary via a central computer.

  • an optical sensor preferably a camera, which detects the road surface can also be used to determine a wet road.
  • an assistance function is initiated automatically, which performs a preventive measure to prevent aquaplaning or at least to reduce the risk of aquaplaning.
  • such an assistance function may represent a visual, audible and / or haptic warning of the driver before aquaplaning, for example by displaying the risk of aquaplaning in the instrument cluster of the vehicle to the driver.
  • Another measure may be, in particular if the driver does not respond to the warning that a triggered by an actuation of the brake pedal of the motor vehicle deceleration request is forwarded for implementation to the drive motor of the motor vehicle and is implemented there such that a blocking of the vehicle wheels is avoided .
  • An assistance function may also be that an acceleration request triggered by an actuation of the gas pedal of the motor vehicle is executed with a lower value over a longer period of time than the acceleration request or is completely suppressed. This prevents, for example, that aquaplaning actually occurs due to strong acceleration.
  • the assistance function can be that the damping of the chassis of the motor vehicle is adjusted, in particular set hard.
  • an assistance function is important that sets or reduces the vehicle speed to a maximum value, preferably 80 km / h, which is the recommended speed at which the vehicle does not float, ie no aquaplaning.

It is particularly advantageous if the driving dynamics control is parameterized in such a way that a blocking is avoided for an electronically requested braking power for the individual vehicle wheels.
