Integration of starter current control device and on-board electrical system disconnecting switch

A module for connecting to only one starter battery and to an on-board electrical system by a transducer, comprising:

• a starter control device and an on-board electrical system disconnector, wherein the transducer is connected to a starter circuit including the only one starter battery from an on-board electrical system side via the starter control device and via the on-board electrical system disconnector;
• wherein the on-board electrical system is uncoupled from the starter circuit during a starting process and wherein the starter control device and the on-board electrical system disconnector are integrated in the module;
• a first quasi-diode disposed between the on-board electrical system side and the starter control device, wherein the first quasi-diode is closed in a base state, wherein, during a starting process, the first quasi-diode is open and a voltage of the on-board electrical system is monitored, and wherein the first quasi-diode is closed and the starting process is terminated in an event of a voltage falling below a predetermined level on the on-board electrical system side or in an event of a failure of the transducer during the starting process;
• wherein the starter control device comprises a starter switch that switches on a starter motor;
• a second quasi-diode that is switched in series with the first quasi-diode and that is parallel to the starter switch and wherein a voltage support point is provided between the first quasi-diode and the second quasi-diode;
• and
• a series resistor that is connected in series with the starter switch.
