The redundancy is done for security reasons, since an incorrect signal can have serious consequences.

  • the vehicle brake system shown schematically in FIG. 1 with distance control comprises a brake actuation device 1 for specifying a brake pressure to a control device 2, by means of which the brake pressure for actuating wheel brakes 3, 4, 5, 6 can be modulated in a wheel-selective manner depending on the operating and driving state variables detected by sensors.
  • the brake actuation device 1 consists of a brake booster 8 which can be actuated by means of a brake pedal 7 and which is followed by a master brake cylinder 9 which is preferably designed as a tandem master brake cylinder.

Monitoring of the pressure sensor 22 can be carried out with the aid of the diaphragm travel sensor 13, in that the signals of the pressure and diaphragm travel sensor with a predefined characteristic or a map are compared.

Abstract

L'invention concerne un système de freinage dans lequel la valeur de consigne de freinage spécifiée par le conducteur ou réglée au moyen d'un dispositif de freinage externe est détectée sur la base de signaux d'un capteur de pression (22) et d'un détecteur de course (13). Il est possible de surveiller la fiabilité du capteur de pression (22) par l'intermédiaire du détecteur de course (13) si le système de freinage comporte, par exemple, un amplificateur d'effort de freinage actif pourvu d'une électrovalve supplémentaire et d'un détecteur de course de pédale ou de membrane pour la réalisation d'un servofrein. Un capteur de pression redondant supplémentaire s'avère alors inutile.
