Embodiment Construction

[0029] figure 1 A starter system 2 for an internal combustion engine (not shown) is shown schematically. In the case of the starter system 2 according to the present exemplary embodiment, the starter pinion of the starter system 2 is not permanently connected to the internal combustion engine, but only during starting of the internal combustion engine.

[0030] Starter system 2 has a motor starter 4 and an actuation relay 14 , which are each electrically conductively connected to a supply voltage source 6 . Instead of the actuation relay 14 , a conventional ignition switch can also be provided.

[0031] Motor starter 4 has a starter motor 8 and a starter relay 10 , which has an actuation terminal 50 , referred to as a terminal 50 , a starter relay coil 16 and a starter relay switch 18 . The starter relay switch 18 in this embodiment has two working contacts and a contact bridge for connecting the working contacts. It is also possible to use starter relay switches with only ...

Abstract

The invention relates to a method for detecting a not-opening starter relay switch of a starter relay. The invention relates to a method for detecting a not-opening starter relay switch of a starter relay of a starter system for an internal combustion engine, wherein the starter relay has a pull-in winding and a holding winding which are integrally connected electrically at a drive terminal of the starter relay in a series circuit way, wherein the height of a voltage sloping on the holding winding is detected, voltage sloping on the holding winding is detected when the starter relay (10) is not driven, the amount of the detected voltage is compared with an error voltage value, and an error signal, indicating a non-opening starter relay switch is generated when the detected voltage is located in an error interval containing the error voltage value.

Description

technical field [0001] The invention relates to a method for identifying an open starter relay switch of a starter relay, and to a computing unit and a computer program for carrying out the method. Background technique [0002] A starter (starter) for an internal combustion engine can basically be an electric motor with an upstream planetary or spur gear and a clutch that connects the starter pinion driven by the electric motor with the Ring gear engagement (einspuren) at the crankshaft of an internal combustion engine. The force required for the engagement can be generated by a starter relay, the armature of which is connected via a lever to the engagement unit (starter pinion with freewheel). [0003] If the starter circuit (Kl. (class) 50) is closed, for example by the ignition switch, the relay armature is attracted by the attraction winding and pushes the pinion into the ring gear by means of the clutch. If the pinion is far enough in the ring gear, the relay armature...
