Circuit arrangement for control of starter relay of starter for car's IC engine has between computer and starter relay, storage circuit which is designed for maintenance of existing control signal for starter relay

摘要

A circuit arrangement for the control of a starter relay of a starter for a car's IC engine has a battery (20) that is connected electrically with the starter relay (4) and a computer (19) that is located in the control circuit of the starter relay. Between the computer and the starter relay is located a storage circuit (2) which during a time-limited low voltage of the battery is designed for the maintenance of the existing control signal for the starter relay. The storage circuit has a flip-flop (14,15). The flip-flop can be set by an RC-circuit (17,18) so that the starter relay is set into the inactive state with the reapplication of the battery voltage after a power failure.
