ABSTRACT:
A system generates a signal to activate the brake lights of a motor vehicle. An accelerator pedal position change parameter is determined, which represents the variation over time of the accelerator pedal that can be actuated by the driver. This accelerator pedal position change parameter is compared with at least one predefinable threshold value. The signal for activating the brake lights is then generated as a function of this comparison. The threshold value is predefined as a function of at least one stability/safety parameter, which represents the instantaneous driving stability of the vehicle and/or the instantaneous driving safety of the vehicle. The method and the device provide an improved means to warn the trailing vehicles of an impending hazard (for example, an obstacle, skidding of the vehicle or a slippery road surface) via the brake lights in a timely and reliable manner.
