Abstract
A driver assistance system includes a first measuring device for determining the distances to a water surface, which includes at least two distance sensors. A first distance sensor measures a first distance to a water surface, in that the distance is determined perpendicularly downward from the first sensor to the water surface, and the second distance sensor measures a second distance to a water surface, in that the distance is also determined perpendicularly downward from the second sensor to the water surface. A second measuring device determines an instantaneous pitch angle of the vehicle. A processing unit is coupled to the first and second measuring devices. The processing unit determines an instantaneous water surface plane as a function of the first distance, the second distance, and the instantaneous pitch angle of the vehicle. A display unit indicates the instantaneous water surface plane in relation to the vehicle.
