Method and device for controlling at least one driver assistance system of a vehicle

摘要

In a method and a device for controlling a driver assistance system of a vehicle, a process is carried out which includes the steps of emitting light of at least one wavelength onto a road surface under the vehicle, detecting the light reflected by the road surface, acquiring at least one piece of information on the nature of the road surface using the detected reflected light, transmitting the information on the nature of the road surface to the driver assistance system, and modifying at least one parameter of the driver assistance system such that the driver assistance system reacts depending on the nature of the road surface.

1. A method for controlling at least one driver assistance system of a vehicle, the at least one driver assistance system comprising a stability adjuster, the method comprising:
emitting light of at least one wavelength onto a roadway surface under the vehicle; detecting the light of at least one wavelength reflected by the roadway surface; acquiring at least one information item relating to a condition of the roadway surface based on the detected reflected light; transmitting the at least one information item to the at least one driver assistance system; and modifying a time for intervention y the stability adjuster based on a comparison of a required coefficient of friction with a coefficient of friction between wheels of the vehicle and the roadway surface estimated using the condition of the roadway surface, the required coefficient of friction being determined from the vehicle's velocity and steering wheel lock for cornering.
