Abstract

Zur Erhöhung der Zuverlässigkeit bei der Ansteuerung einer Zündendstufe durch ein Motorsteuergerät (1) wird vorgeschlagen, die Zündendstufe (3) nicht direkt mit dem Motorsteuergerät (1) zu verbinden, sondern durch dazwischen geschaltete Kopplungsmittel (4) eine potenzialfreie Kopplung zwischen dem Motorsteuergerät (1) und der Zündendstufe (3) zu ermöglichen, so dass sich ein Masseversatz zwischen dem Motorsteuergerät (1) und der Zündendstufe (3) oder Potenzialverschiebungen nicht auf das sichere Ein- bzw. Ausschalten des in der Zündendstufe (3) enthaltenen Zünders (7) auswirken. Die Kopplungsmittel (4) können zur Herbeiführung der potenzialfreien Kopplung beispielsweise einen Optokoppler oder auch einen Differenzverstärker umfassen.
