Abstract
(DE)
Es wird eine Technik zum redundanten Erfassen einer Betätigung einer Kraftfahrzeug-Bremsanlage beschrieben. Eine zu diesem Zweck vorgesehene Vorrichtung umfasst einen ersten Sensor (10) zum Erzeugen eines auf eine Bewegung einer mechanischen Eingangskomponente der Bremsanlage hinweisenden ersten Sensorsignals sowie einen zweiten Sensor (12) zum Erzeugen eines auf einen Hydraulikdruck in der Bremsanlage hinweisenden zweiten Sensorsignals. Eine mit den beiden Sensoren (10, 12) gekoppelte Verarbeitungseinrichtung (14) ist dazu ausgebildet, wahlweise ein auf Grundlage des ersten Sensorsignals oder ein auf Grundlage des zweiten Sensorsignals erzeugtes Betätigungssignal auszugeben. Das Betätigungssignal weist auf eine Betätigung der Bremsanlage hin.
(EN)
A technique is described for the redundant detection of an actuation of a motor-vehicle brake system. A device which is provided for this purpose comprises a first sensor (10) for generating a first sensor signal which indicates a movement of a mechanical input component of the brake system, and a second sensor (12) for generating a second sensor signal which indicates a hydraulic pressure in the brake system. A processing device (14) which is coupled to the two sensors (10, 12) is configured for optionally outputting an actuation signal which is generated on the basis of the first sensor signal or an actuation signal which is generated on the basis of the second sensor signal. The actuation signal indicates an actuation of the brake system.

L'invention concerne une technique de détection redondante de l'actionnement d'un système de freinage d'un véhicule automobile. Le dispositif destiné à cet effet comprend un premier capteur (10) destiné à produire un premier signal de capteur indiquant un mouvement d'un composant mécanique d'entrée ainsi qu'un deuxième capteur (12) destiné à produire un deuxième signal de capteur qui indique une pression hydraulique dans le système de freinage. Un dispositif de traitement (14) relié aux deux capteurs (10, 12) est conçu pour produire en sortie un signal d'actionnement produit au choix en fonction du premier signal de capteur ou du deuxième signal de capteur. Le signal d'actionnement indique l'actionnement du système de freinage.
