Abstract

본 발명은 자동차의 전원 제어 장치에 관한 것으로, 점화 스위치가 오프된 후에도 일정시간 동안 마이콤내의 기억장치에 전원이 공급되도록 하여 상기 기억 장치에 데이타가 저장되도록 하고, 상기 저장된 데이타가 계속적으로 보존되도록 하므로써 자동차가 최적의 상태로 유지될 수 있도록 한 자동차의 전원 제어 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply control device for an automobile, and the power supply is supplied to a memory device in the microcomputer for a certain time even after the ignition switch is turned off, so that the data is stored in the memory device and the stored data is continuously stored. The present invention relates to a power supply control apparatus for a vehicle so that the vehicle can be maintained in an optimal state.
