- Time ti switched, so controlled for switching is.
- the switching state of the switching device can change only after the time t-i, in particular after a certain, characteristic switching delay or duration, which is determined, for example, by the construction of the switching device.
- At least one further second current path connected in parallel with the first current path, serves for additional energization of the starter motor, preferably for a current supply that is lower than the main current path, for example, a starter pinion of the starter pinion To facilitate starter motor in a ring gear of the internal combustion engine with a smooth rotational movement of the starter motor at low power, or also, as mentioned above, to limit a starting current. It is preferred that at least one of the further current paths connected in parallel with the main current path runs through the adaptation device, that is, in particular, can also be realized as a current path of the switching module.
- the at least one further, parallel-connected current path is referred to as a secondary current path.
- the secondary current path may comprise both only a single and a plurality of parallel current paths.
- An embodiment with exactly three current paths connected in parallel with the first current path is preferred as a secondary current path, so that the starter motor can be energized via different combinations of current paths, in particular also via different currents, in particular start-up currents.
- the switching state of the switching device is checked at a time t 3 after the time ti, in particular after a characteristic switching duration or delay of the switching device.
- a time delay By such a time delay, a reaction time of the switching device can be considered and the reliability in checking can be increased.
- the time t 3 is variably adjustable in the controller.
- the switching state is continuously checked from the time ti. If the desired switching state does not occur within a certain period of time, this is determined and the controller reacts accordingly.
- the secondary current path for energizing the starter motor is energized, and in particular from a time t 0 before the time t.
- the starter motor can be energized with a reduced current intensity compared to the current flow of the main current path, in order to reduce the voltage drop of the vehicle electrical system.

- the current flow of the secondary current path is reduced if, when the nominal state of the switching device is switched on, the check results in a switched-off switching state as actual state.
- the switching device has therefore not reliably switched, and this can be attributed in particular to a voltage dip in the electrical system of the motor vehicle, which reduces the reliability of the switching device when switching.
- This voltage dip can be reduced by the reduced current flow of the secondary current path and thus increase the robustness of the switching device.
- a starter relay as a switching device is no longer achieved the necessary relay coil current for safe switching in a voltage dip.
- the secondary current path is preferably formed with a resistance element of the adaptation device, in particular of the switching module.
- the flow of the secondary flow path can be set in a defined manner, wherein in the case of a plurality of parallel-connected current paths of the secondary current path, preferably each individual current path is respectively formed with such a resistance element.
- the resistance elements can have the same or different resistance values, so that the total current output to the starter motor can be set by supplying different, parallel current paths both by a different number and by a different selection of parallel current paths to be energized.
- the secondary flow path is formed with a switch of the adaptation device, in particular of the switching module, with which the energization of the secondary current path can be switched on and off.
- the switch can in particular be designed as an electronic power switch, for example a power FET.
- each of these current paths is formed with such a switch.
- any desired combinations of the current paths can be energized in order, for example, to control the current intensity, in particular a cranking current, during the energization of the starter motor.
- the energization can then also be completely switched off.
- the energization can be easily, namely by merely switching the switch, adapt and also the controller, in particular the matching device low, namely with simple switches realize.
- the test device is designed such that the switching state of the switching device by means of a current measurement of Current supply of the starter motor is checked. Since the switching device turns on or off the energization of the main current path, the switching state of the switching device can be easily and reliably checked on the basis of the current intensity, in particular of the main current path.

- FIG. 2 shows a schematic circuit diagram of a method for operating the controller 1 illustrated in FIG. 1, the events and states explained below being shown arranged vertically one above the other along a time axis t for a better overview. There are switching characteristics 20-24 and a speed characteristic 25 plotted against the time axis t.
- the times t 0 and t 6 mark a start and an end of a starting operation of the internal combustion engine by means of the starter motor 2, it being noted that the time axis t is not linear, so that equal distances along the time axis t do not necessarily describe the same time duration.

- the switching device 8 is energized, so that the current strength 30 rises rapidly from 0 A to a value between 9 A and 10 A. Due to the low vehicle electrical system voltage 31, however, the resulting current 30 does not suffice to switch the switching device 8 successfully, ie to change the switching state according to the characteristic curve 24 to a switched-on state, so that due to the check at the time t 3 the secondary current path 4 by means of the power switch 7a , 7b, 7c is turned off and consequently the vehicle electrical system voltage 31 increases.

Incidentally, in particular old tion effects or changes of resistors within a circuit for driving the switching device 8 are tolerated to a greater extent. All figures show only schematic not to scale representations. Moreover, reference is made in particular to the drawings for the invention as essential.
