Abstract:
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.
