Abstract

본 발명은 차량 상태에 따라 전자제어장치(ECU)의 전원 전압을 능동적으로 제어하여 소비 전류가 최소화되도록 한 차량 전자제어장치의 소비전류 감소장치에 관한 것으로서, 차량의 축전지(1)에 연결되어 장치로 인가되는 전압을 낮춰 안정 공급하는 전원부(10)와; 상기 전원부(10)로 부터 전원을 공급받아 작동하여 스위치입력부(40)에서 입력되는 신호에 따라 전원변환제어부(30)에 유입 전류의 가압 또는 승압을 명령하면서 장치 전체를 제어하는 마이컴(20)과; 상기 전원부(10)와 마이컴(20) 사이에 구비되어 장치에 인가되는 전류의 전압을 조정하는 전원변환제어부(30)와; 외부 스위치(2)가 병렬로 연결되어 이들 스위치의 상태부를 감지하여 마이컴에 출력하는 스위치입력부(40)와; 상기 전원부(10)와 마이컴(30) 사이에 구비되어 마이컴의 오동작과 전원 불안정시 전원을 일시 차단하여 마이컴(20)을 재작동시키는 리세트부(50)로 구성되어, 차량의 스탠바이 상태에서의 전자제어장치 소비 전류를 정상상태에서 보다 감소시켜 차량이 오랜동안 스탠바이 상태가 유지되어도 축전지가 쉽게 방전되지 않도록 한 것이다.The present invention relates to a device for reducing current consumption of an electronic control device of a vehicle in which a power consumption of an electronic control unit (ECU) is actively controlled according to a vehicle state, thereby minimizing current consumption. The device is connected to a storage battery 1 of a vehicle. A power supply unit 10 for stably supplying the voltage applied thereto; The microcomputer 20 which controls the entire apparatus while instructing the power supply control unit 30 to pressurize or boost the inflow current according to a signal input from the switch input unit 40 to operate by receiving power from the power supply unit 10. ; A power conversion controller 30 arranged between the power supply unit 10 and the microcomputer 20 to adjust a voltage of a current applied to the device; A switch input unit 40 connected to the external switches 2 in parallel to detect state parts of these switches and output them to the microcomputer; The reset unit 50 is provided between the power supply unit 10 and the microcomputer 30 to temporarily shut off the power supply when the microcomputer malfunctions and the power unstable. The current consumption of the electronic controller is reduced more than in the normal state so that the battery is not easily discharged even when the vehicle is in a standby state for a long time.
