Patent ID: 7156065

Claim:
A trigger circuit for an engine starter relay comprising: a switching device for switching an output of the engine starter relay to a reference potential and for activating the engine starter relay as a function of a trigger signal, which is applied at a trigger input of the switching device; a first logic circuit for logically linking a first digital signal of a computer device and a second digital signal of an operating device; a second logic circuit for logically linking an output signal of the first logic circuit to the first digital signal; a storage device for temporarily storing a state at outputs of the first and second logic circuits, an output of the storage device being connected to the trigger input of the switching device; and a diode arranged between the switching device and an output of the engine starter relay, wherein the activation of the engine starter relay is ensured in the event that a supply voltage at the computer device falls below a specified value with a resulting activation of a reset signal.
