Abstract

An electronic circuit comprises conventional evaluation units (2,3,5) and an acceleration sensor (1) to decide whether to switch on the warning flashers or to switch them off. Only during full braking does a time- delayed switch-on take place.

Description

Eine Vollbremsung würde eine Frequenzänderung des Ausgangssignals vom Beschleunigungssensor (1) zur Folge haben. Diese würde über einen Tiefpaß­ filter (2) in ein frequenzabhängiges Spannungssignal umgeformt.Full braking would result in a change in the frequency of the output signal from the acceleration sensor ( 1 ). This would be converted into a frequency-dependent voltage signal using a low-pass filter ( 2 ).

Eine Auswerteelektronik (3 oder 5) filtert dann, aus der Spannungshöhe (welche ein Maß für die Bremsstärke ist) und der Zeitdauer der anstehenden Bremsphase, einen Schaltvorgang aus. Dieser ist bei (3) zeitlich begrenzt oder bei (5) kann der Schaltvorgang nur mit eine Löschtaste (6) wieder rückgesetzt werden.An electronic evaluation unit ( 3 or 5 ) then filters out a switching operation from the voltage level (which is a measure of the braking force) and the duration of the braking phase. At ( 3 ) this is limited in time or at ( 5 ) the switching process can only be reset with a delete button ( 6 ).

Der so ausgelöste Schaltvorgang setzt die Warnblinkanlage (4) in Betrieb.The switching process triggered in this way puts the hazard warning system ( 4 ) into operation.

Die manuelle Auslösung der Warnblinkanlage (7) bleibt davon unberührt.The manual triggering of the hazard warning lights ( 7 ) remains unaffected.

Claims (2)

1. Eine elektronisch Anordnung, bestehend aus einer elektronischen Auswerteelektronik (2, 3 oder 5) mit bekannter Technik und einem Beschleunigungssensor (1), entscheidet über das Ein- und Ausschalten der Warnblinkanlage (4) in Kfz.1. An electronic arrangement consisting of electronic evaluation electronics ( 2 , 3 or 5 ) with known technology and an acceleration sensor ( 1 ) decides on the switching on and off of the hazard warning lights ( 4 ) in motor vehicles. 2. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß diese nur bei Vollbremsung ein zeitlich befristetes Einschalten der Warnblinkanlage bewirkt.2. Arrangement according to claim 1, characterized in that this the hazard warning lights are only switched on for a limited time when the brakes are on causes.
