In a method and apparatus for assisting the driver of a vehicle in maintaining a traffic lane limited by traffic lane markings, the traffic lane markings and the position of the vehicle in the traffic lane are detected. Upon an actual or impending change of traffic lanes a lane change warning is output to the driver of the vehicle in a first step, and a course correcting actuating intervention counteracting the lane change is carried out in a second step. The actuating intervention is carried out only if the change of traffic lanes is impermissible due to the type of traffic lane marking to be crossed during the traffic lane change, or if the lane change is not possible without danger due to collision-endangering objects present on the side of the traffic lane.

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.

In a method of determining the traction of motor vehicle wheels on wet pavements, a surge force generated by a water film on the pavement in front of at least one of the vehicle wheels is measured and from the measured surge force value and the instantaneous vehicle speed a critical speed at which the vehicle wheel will aqua-plane is determined and this critical speed is displayed to the driver or it is used to control a vehicle drive unit to keep the vehicle speed below the critical speed.
