BATTERY ON/OFF SENSING CONTROL DEVICE FOR AUTO TEMPERATURE CONTROLLER OF CAR

摘要

PURPOSE: A battery on/off sensing control device for an automatic temperature controller of a vehicle is provided to cut off the operation of a thyristor after passing for a certain period of time within MICOM activation time by adding a transistor as a parallel circuit of the thyristor. CONSTITUTION: A battery on/off sensing control device for an automatic temperature controller of a vehicle comprises a battery mounting unit(10), a regulator(20), a MICOM, a thyristor(40), and a cutoff device. The regulator appropriately controls the voltage of direct current of a battery from 12V to 5V. The MICOM comprises an input port(31) obtained the voltage controlling voltage drop in the regulator. After the MICOM is activated and a certain period of time is passed, the thyristor obtains the part of the voltage that the MICOM obtains. The change of the voltage is generated in the input port of the MICOM. The thyristor detects that the MICOM initially mounts the battery. The cutoff device cuts off the operation of the thyrister after passing the certain period of time among the MICOM activation time.
