Method for positioning crankshaft of internal combustion engine of vehicle, involves activating starter motor for rotating crankshaft, and decelerating starter motor at predetermined position of crankshaft to position crankshaft

摘要

The method involves activating a starter motor for rotating a crankshaft, and decelerating the starter motor at a predetermined position of the crankshaft to position the crankshaft. An armature or an armature winding of the starter motor is short circuited by a relay, a semiconductor switch, a resistor or a coil, for decelerating the starter motor. The starter motor is operated with a free-wheel i.e. front tooth free-wheel, during deceleration of the starter motor. An independent claim is also included for a positioning arrangement for positioning a crankshaft of a drive assembly i.e. internal combustion engine.
