Abstract
A circuit arrangement for the automatic engagement of a motor vehicle hazard warning system in case of impact accidents and emergency braking situations which includes an inertia switch with high response threshold and an acceleration sensor connected in parallel thereto with low response threshold whose output signals each serve for engaging the hazard warning system. The output of the acceleration sensor is connected to an evaluation circuit with an integrator and an threshold switch which prevents that also pulse-shaped output signals of the acceleration sensor lead already to turning on the hazard warning system.
