A method is described for operating a controller for a starting apparatus for starting an internal combustion engine in a vehicle, the controller controlling an engagement apparatus, which encompasses the starting apparatus, so as to engage a starter pinion into the ring gear of an internal combustion engine, in particular using a start-stop operating strategy. In order to improve vehicle convenience by the fact that start-stop operation can be implemented with quick and reliable availability of the internal combustion engine, at least one operating parameter of the engagement apparatus is sensed and evaluated by the controller, and the controller adapts the control of the engagement apparatus to the at least one operating parameter.

An electrical component having a core and a first and second coil positioned around the core is controlled in such a manner, that in response to the second coil being switched off, the first coil is short-circuited via a quenching circuit to quench the inductive load of the second coil.

An electrical component having a primary winding, a first field-effect transistor, configured as a switch of the primary winding, for switching the primary winding, a quench winding for quenching the inductive load of the primary winding when switching off the primary winding, and a second field-effect transistor, configured as a switch of the quench winding, for switching the quench winding. In the process, the first field-effect transistor is operated in linear operation and the second field-effect transistor is operated in linear operation or in a clock-pulsed operation between the linear operation and a switched-off state during a switching-off process of the quench winding.

A switching device has an electromagnetic switching element and a controller, the switching element including two coils on one core which act on a shared armature. In order to implement an operation of the armature to be activatable as rapidly and simply as possible with low power consumption, the controller is designed to have a switch in the current path of the coil in each case to activate each coil.

The invention relates to a starting method for internal combustion engines in motor vehicles, comprising a start-stop system, and to a starting device (10) for carrying out said method, said starting device comprising a starter motor (11) and an insertion device (12, 20) which axially inserts a slip-on pinion (13) into a crown gear (14) of the internal combustion engine when a stop cycle begins. In order to minimize the period until the engine can be restarted, the pinion (13) is resiliently inserted into the still rotating crown gear (14) by means of a pressure spring (25) when the stop phase begins, once the internal combustion engine (15) is switched off but before it comes to a standstill and with the starter motor (11) switched off.
