Abstract:
(EN) A diagnostic system for a vehicle electrical system having a DC-DC voltage converter and a voltage regulator is provided. A first monitoring application sets a first voltage regulator state flag to be the same as a first fault value when a first voltage value is greater than a first maximum voltage value. A first diagnostic handler application switches a high-voltage switch and a low-voltage switch to an open operation state when the first voltage regulator state flag is the same as the first fault value. A second monitoring application sets a second voltage regulator state flag to be the same as a second fault value when a second voltage value is less than a first minimum voltage value. A second diagnostic handler application switches the high-voltage switch and the low-voltage switch to the open operation state when the second voltage regulator state flag is the same as the second fault value.
(FR) La présente invention concerne un système de diagnostic pour un système électrique de véhicule ayant un convertisseur de tension CC-CC et un régulateur de tension. Une première application de surveillance définit un premier indicateur d'état de régulateur de tension pour qu'il soit identique à une première valeur d'erreur lorsqu'une première valeur de tension est supérieure à une première valeur de tension maximale. Une première application de gestionnaire de diagnostic commute un commutateur haute tension et un commutateur basse tension vers un état de fonctionnement ouvert lorsque le premier indicateur d'état de régulateur de tension est le même que la première valeur d'erreur. Une seconde application de surveillance définit un second indicateur d'état de régulateur de tension pour qu'il soit identique à une seconde valeur d'erreur lorsqu'une seconde valeur de tension est inférieure à une première valeur de tension minimale. Une seconde application de gestionnaire de diagnostic commute le commutateur haute tension et le commutateur basse tension vers l'état de fonctionnement ouvert lorsque le second indicateur d'état de régulateur de tension est le même que la seconde valeur d'erreur.
(KO) DC-DC 전압 컨버터 및 전압 레귤레이터를 갖는 차량 전기 시스템을 위한 진단 시스템이 제공된다. 제1 모니터링 어플리케이션은 제1 전압 값이 제1 최대 전압 값보다 클 때 제1 폴트 값과 동일한 제1 전압 레귤레이터 상태 플래그를 설정한다. 제1 진단 핸들러 어플리케이션은 제1 전압 레귤레이터 상태 플래그가 제1 폴트 값과 동일할 때 고전압 스위치 및 저전압 스위치를 개방 동작 상태로 전환시킨다. 제2 모니터링 어플리케이션은 제2 전압 값이 제1 최소 전압 값보다 작을 때 제2 폴트 값과 동일한 제2 전압 레귤레이터 상태 플래그를 설정한다. 제2 진단 핸들러 어플리케이션은 제2 전압 레귤레이터 상태 플래그가 제2 폴트 값과 동일할 때 고전압 스위치 및 저전압 스위치를 개방 동작 상태로 전환시킨다.
