The on-board electrical system control unit 16 includes an on-board electrical system module, which performs the requisite reverse switching operations and has one further terminal, by on-board electrical system components required for starting an operation can be supplied with voltage. These on-board electrical system components are supplied at maximum priority, and if the supply battery is too greatly discharged are jointly supplied by both batteries, but it is nevertheless assured that during the starting process the other on-board electrical system components are not connected to the starter battery.</p> |
