Abstract
(DE)

Eine Startvorrichtung (160) für eine Brennkraftmaschine hat einen Startermotor (140) sowie eine Schaltsteuereinrichtung zum Ansteuern des Startermotors (140). Letztere umfaßt einen Leistungsschaltbaustein (165, 170, 175, 180), der den Startermotor (140) mit einer Spannungsquelle (130) verbindet. Ferner weist die Schaltsteuereinrichtung eine Steuerelektronik (195) zur Ansteuerung des Leistungsschaltbausteins (165, 170, 175, 180) sowie eine Betätigungseinrichtung (135) zur Aktivierung der Steuerelektronik (195) auf. Die Steuerelektronik (195) ist derart ausgelegt, daß sie mit einer Versorgungsspannung betrieben werden kann, die geringer ist als 5 V. Dies stellt den sicheren Betrieb der Startvorrichtung auch bei im Zuge des Startvorgangs abfallender Versorgungsspannung sicher.


(EN)

The invention relates to a starter device (160) for an internal combustion engine, comprising a starter motor (140) and a switching control device for controlling the starter motor (140). The latter comprises a power switching module (165,170, 175, 180) connecting the starter motor (140) to a voltage source (130). The switching control device also comprises a control electronics system (195) used to control the power switching module (165,170, 175, 180), and an actuating device (135) used to activate the control electronics system (195). The control electronics system (195) is configured in such a way that it can be operated with a supply voltage which is less than 5V, thereby ensuring safe operation of the starter device even if the supply voltage falls off in the wake of the starting process.
