Abstract

A device for starting an internal combustion engine of a motor vehicle includes a starter motor having an actuator for engaging a pinion, drivable by the starter motor, with a ring gear, and a control unit which activates a switching output stage associated with the actuator and a switching output stage associated with the starter motor. The starting time of the internal combustion engine is substantially reduced by providing the starter device with a control unit.
