Method for engaging the starter pinion of a starter with the starter ring gear of an internal combustion engine during the running-down of the internal combustion engine
First Claim
1. A method for engaging a starter pinion of a starter with a starter ring gear of an internal combustion engine during a running-down of the internal combustion engine, wherein the internal combustion engine has an arrangement for determining a rotational speed and a rotational direction of a crankshaft, the method comprising:
- determining whether the rotational speed of the internal combustion engine is below a predetermined maximum speed and above a predetermined minimum speed;
determining whether the rotational direction of the crankshaft corresponds to a forward rotational direction; and
engaging the starter pinion with the starter ring gear if;
a) the rotational speed of the internal combustion engine is below the predetermined maximum speed and above the predetermined minimum speed; and
b) the rotational direction of the crankshaft corresponds to the forward rotational direction.

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.

5. A control system for a starter of an internal combustion engine, comprising:
-
a controller for engaging a starter pinion of a starter with a starter ring gear of an internal combustion engine during a running-down of the internal combustion engine; and
an arrangement for determining a rotational speed and a rotational direction of a crankshaft, wherein the arrangement for determining the rotational speed and the rotational direction of the crankshaft includes a signal-generating disk which is coupled to the internal combustion engine and has a marking, wherein the marking includes an alternating arrangement of teeth and tooth spaces, wherein a first sensor and a second sensor are assigned to the signal-generating disk, wherein the first and second sensors each generate an electrical signal configured to represent one of two different signal levels, a first signal level being assigned to a tooth and a second signal level being assigned to a tooth space, and wherein the rotational direction of the crank shaft is ascertained by utilizing a) one of a rising and falling edge of an electrical signal of one of the first and second sensors, and b) and a signal level of an electrical signal of the other one of the first and second sensors;
wherein the starter pinion is engaged with the starter ring gear if;
a) the rotational speed of the internal combustion engine is below the predetermined maximum speed and above the predetermined minimum speed; and
b) the rotational direction of the crankshaft corresponds to the forward rotational direction.
