Abstract
A warning signal control system is equipped with an optical warning signal actuator, preferably the headlight flasher which is already available, an acoustic warning signal actuator for emitting a vehicle-external warning sound which differs from the conventional horn signal, at least one electronic control unit, and a single operating switch. The switch signal is an input signal of the control unit by which both the optical warning signal actuator as well as the acoustic warning signal actuator can be activated separately or together. In the process, the activation of the optical warning signal actuator and/or the acoustic warning signal actuator can be controlled at least depending on the vehicle speed when the operating switch is actuated. The operating switch is the operating element which is already provided for the conventional light flashing function and is used here in a multifunctional manner.
