Abstract

Système de commande pour automobile dans lequel la force de freinage est maintenue sans que l'on ait besoin de maintenir la pression sur la pédale de frein pendant les arrêts de l'automobile. L'automobile peut facilement démarrer lorsqu'elle est immobilisée sur une pente ascendante et l'alarme est déclenchée lorsque le freinage est difficile pendant l'arrêt, lorsque le frein à main est actionné à l'état freiné ou lorsque la clé est retirée pendant que les phares sont allumés. Par ailleurs, la force de freinage lors de l'arrêt en marche avant sur une pente ascendante et lors de l'arrêt en marche arrière sur une pente ascendante peut réglée au moyen des commutateurs d'inclinaison (17, 17').
