Abstract
The device according to the invention relates to a device for detecting a risk of aquaplaning which arises during the driving mode of a vehicle. The device contains for this purpose first means which determine a first propulsion variable which describes the propulsion of the vehicle which is to be expected on the basis of the operating state of the engine and/or of the drive train. In addition the device contains second means which determine a second propulsion variable which describes the propulsion occurring during the driving mode of the vehicle and which arises due to the longitudinal acceleration acting on the vehicle. The presence of the risk of aquaplaning is inferred as a function of a deviation between the first propulsion variable and the second propulsion variable.
