Abstract
A method is provided for engaging a starter pinion of a starter with a starter ring gear of an internal combustion engine during the running-down of the internal combustion engine, which internal combustion engine has an arrangement for determining rotational speed and rotational direction of a crankshaft. The starter pinion is engaged with the starter ring gear when the following conditions are satisfied: a) the speed of the internal combustion engine is below a maximum speed and above a minimum speed; and b) the rotational direction corresponds to the forward rotational direction of the crank shaft.
