Abstract

본 발명은 자동차 밧데리에 충전되는 전원없이 밧데리의 전원이 일정레벨 이하로 방전되면 엔진을 강제로 동작시켜 방전된 밧데리의 전원을 재충전하여 시동장치를 포함하는 자동차의 전기장치에 정상적으로 전원을 공급할 수 있도록 하는 자동차 밧데리 방전방지 자동시동장치 및 동작제어방법에 관한 것으로, 종래에는 밧데리로부터 전원이 모두 방전되면 자동차의 각종 전기장치에 전원을 정상적으로 공급하지 못하는 결점을 가지고 있었다. 본 발명은 예시도면 제1도에서와 같이, 검출하고자 하는 밧데리 방전레벨을 일정레벨값으로 설정하는 기준값 설정장치(8)를 구성하고, 상기 밧데리(20)로부터 출력되는 출력전압을 디지탈 전압값으로 변환하는 아날로그/디지탈 변환장치(50)를 구성하며, 상기 디지탈 변환된 밧데리 전압값과 설정된 기준값을 대비하여 검출된 전압값이 기준값에 비해 작으면 엔진 동작을 위한 구동제어신호를 출력하는 마이콤(6)을 구성하는 한편, 상기 마이콤(60)의 제어하에 밧데리(20)로부터 출력되는 전원을 시동장치(40)에 강제로 공급하여 엔진을 동작시키는 시동장치 구동부(30)로 구성된 것이다.According to the present invention, when the power of the battery is discharged to a predetermined level or less without the power charged to the vehicle battery, the engine is forcibly operated to recharge the power of the discharged battery so that power can be normally supplied to the electric device of the vehicle including the starting device. The present invention relates to an automatic start device and an operation control method for preventing vehicle battery discharge, and in the related art, when all power is discharged from a battery, power supply to various electric devices of a vehicle cannot be normally supplied. As shown in FIG. 1, the present invention constitutes a reference value setting device 8 for setting a battery discharge level to be detected to a constant level value, and output voltage output from the battery 20 as a digital voltage value. An analog / digital converter 50 for converting, and if the detected voltage value is smaller than the reference value compared to the digitally converted battery voltage value and the set reference value (6) for outputting a drive control signal for the engine operation (6) ) And a starter driver 30 for operating the engine by forcibly supplying the power output from the battery 20 to the starter 40 under the control of the microcomputer 60.

Claims

In a vehicle electric supply device which supplies power output from the battery 20 and the engine electric generator to the vehicle electric device 10, the battery discharge level to be detected is a reference value for setting a constant level value and an engine operating time. A setting device 80, an analog / digital converter 50 for converting an output voltage output from the battery 20 into a digital voltage value, and a voltage detected by comparing the digitally converted battery voltage value with a set reference value If the value is smaller than the reference value, the microcomputer 60 outputs a drive control signal for operating the engine, and the power set from the battery 20 under the control of the microcomputer 60 is supplied to the starter 4 to a predetermined schedule. The vehicle battery discharge automatic starter, characterized in that comprises a starter driving unit 30 for operating the engine for a time.

In supplying the electric power generated from the battery 20 and the engine electric generator to the electric device of the vehicle including the starting device, the reference value of the battery discharge level to be detected and compared is set by operating a button of the reference value setting device and the engine operating time. When the detected voltage value is smaller than the reference value, the engine driving control signal is output and the engine is forcibly operated for a predetermined time period by detecting the output voltage output from the battery 20 and comparing with the set reference value. Method for controlling the operation of the vehicle battery discharge automatic starter, characterized in that for recharging the power discharged from the electricity generating device to the battery (20).
