(FR) SYSTÈME DE VÉHICULE DOTÉ D'UN SYSTÈME DE FREINAGE À TOLÉRANCE AUX DÉFAILLANCES D'ESC
Abstract
(DE) Die Erfindung betrifft ein Fahrzeugsystem (100) für ein Fahrzeug (200), insbesondere Nutzfahrzeug (202), mit einem elektronisch steuerbaren pneumatischen Bremssystem (101), und einer elektronisch steuerbaren Lenkeinrichtung (103). Das elektronisch steuerbare pneumatische Bremssystem (100) hat eine redundante Steuereinheit (104), die im Falle eines Ausfalls einer elektronischen Stabilitätsregelung (ESC1) des Bremssystems (101) während einer Fahrt die Bremskreise (2, 4) steuert. Im Falle des Ausfalls der elektronischen Stabilitätsregelung (ESC1) während der Fahrt steuert die redundante Steuereinheit (104) die Vorderachse (VA) mit einem Vorderachs-Redundanzbremsdruck (pRVA) und/oder die Hinterachse (HA) mit einem Hinterachs-Redundanzbremsdruck (pRHA) achsenweise an und die elektronisch steuerbare Lenkeinrichtung (103) führt querstabilisierende Lenkeingriffe aus zum Halten des Fahrzeugs (200) in einem Toleranzkorridor (TK) einer vorgegebenen Solltrajektorie (TSoll) des Fahrzeugs (200). Die Erfindung umfasst auch ein Fahrzeug (200) sowie ein Verfahren (300).
(EN) The invention relates to a vehicle system (100) for a vehicle (200), more particularly a utility vehicle (202), comprising an electronically controllable pneumatic braking system (101) and an electronically controllable steering device (103). The electronically controllable pneumatic braking system (101) has a redundant control unit (104), which controls the brake circuits (2, 4) in the event of a failure of an electronic stability control system (ESC1) of the braking system (101) during a journey. In the event of the failure of the electronic stability control system (ESC1) during the journey, the redundant control unit (104) controls the front axle (VA) with a front-axle redundancy brake pressure (pRVA) and/or the rear axle (HA) with a rear-axle redundancy brake pressure (pRHA) axle by axle and the electronically controllable steering device (103) performs laterally stabilizing steering interventions in order to keep the vehicle (200) in a tolerance corridor (TK) of a predefined target trajectory (TSoll) of the vehicle (200). The invention also relates to a vehicle (200) and to a method (300).
(FR) L'invention concerne un système de véhicule (100) pour un véhicule (200), en particulier un véhicule utilitaire (202), comprenant un système de freinage pneumatique à commande électronique (101) et un dispositif de direction à commande électronique (103). Le système de freinage pneumatique à commande électronique (101) comprend une unité de commande redondante (104) qui commande les circuits de freinage (2, 4) en cas de défaillance d'un système de commande de stabilité électronique (ESC1) du système de freinage (101) pendant un trajet. En cas de défaillance du système de commande de stabilité électronique (ESC1) pendant le trajet, l'unité de commande redondante (104) commande l'essieu avant (VA) avec une pression de frein de redondance d'essieu avant (pRVA) et/ou l'essieu arrière (HA) avec une pression de frein de redondance d'essieu arrière (pRHA) essieu par essieu et le dispositif de direction à commande électronique (103) effectue des interventions de direction à stabilisation latérale pour maintenir le véhicule (200) dans un couloir de tolérance (TK) d'une trajectoire cible (TSoll) prédéfinie du véhicule (200). L'invention concerne également un véhicule (200) et un procédé (300).
