POWER CONTROL CIRCUIT FOR AUTOMOTIVE VEHICLES AND THE LIKE

摘要

A power control circuit operative to enable start-up of a vehicle engine in response to a predetermined sequence of events. Upon opening one or more doors by means of a keying circuit actuating a keyable control circuit, a control signal is provided to a timing circuit which in turn provides an enabling signal to an enabling circuit for a predetermined period of time during which engine start-up may be effected by depressing the brake pedal and subsequently actuating the ignition switch. The timer output and the actuation of the brake pedal switch cause energization of a solenoid which normally prevents actuation of the ignition switch. Energization of this solenoid enables actuation of the ignition switch, which in turn mechanically prevents the solenoid from preventing further actuation of the ignition switch after the solenoid is again de-actuated upon either expiration of the enabling signal or de-actuation of the brake light switch.
