Abstract

Bei Mehrfachanordnung von Sensoren (Fahrpedal- und Drosselklappengeber, Luftmassenmesser etc.) in Kraftfahrzeugen werden die Versorgungsspannung (V5int) eines im Motorsteuergerät ST in einem Mikrocontroller (νC) integrierten Analog/Digital-Konverters ADC und die Sensor-Referenzspannungen (V5a, V5b) in einem gemeinsamen Spannungsregler (SR) mit gemeinsamer Spannungsreferenz Ref1, die überwacht wird (ÜW1), erzeugt. Die Versorgungsspannung V5int wird zusätzlich von einer Überwachungsschaltung ÜW2 mit unabhängiger Spannungsreferenz Ref2 überwacht.
