Abstract
A motor vehicle includes an adjustable steering assistance. The adjustable steering assistance includes an evaluation unit for evaluating the grip of a road travelled, in which the extent of the steering assistance is variable as a function of the result of the road grip evaluation. The effectiveness of the steering assistance adjustment is due to the fact that the driver is accustom to the hand moment exerted on the steering wheel during steering, conventionally as a fixed relationship to the torque, which for steering the wheels of the motor vehicle has to be exerted thereon. Consequently, the lower the steering resistance the less road grip as a general rule. In that the extent of the steering assistance is varied, a road with less grip can thus be suggested to the driver in order to prompt him to a correspondingly careful driving style.
