Abstract:
PURPOSE: A system and method for managing a vehicle battery are provided to improve the marketability of a vehicle by making a refresh result of the battery as data. CONSTITUTION: An alternator supplies power to a battery and an electrical load of a vehicle. The battery supplies the power from the alternator to the electrical load. A battery monitoring unit(120) monitors the state of the battery. A vehicle information collecting unit(150) collects condition state information. A control unit(170) performs the charging recovery of the battery.

Abstract:
PURPOSE: A control circuit of a high luminous headlamp for a vehicle is provided to prevent a delay of an operating time by alternating relays. CONSTITUTION: A controller(10) controls HID(High Intensity Degree) headlamps(20). A pair of HID headlamps(20) is installed in the left and the right of a vehicle. A DRL(Daytime Running Lamp) unit(30) controls a day running to secure a visibility of a driver during the day. A multi function switch(40) turn on/off the HID headlamps selectively. A pair of HID relays(21a,21b) are connected each other in parallel. The DRL unit and the multi function switch are connected each other in parallel. The HID headlamps are lighted by independently turning on the HID relays through an operating signal from the DRL unit or through the multi function switch. Thereby, a circuit to accept an operating signal of a headlamp switch is eliminated. Moreover, the intensity of the HID headlamps is maintained by removing an alternating time of the HID relays and removing a voltage falling event.

PURPOSE: A circuit for driving fan motor of automobile is provided to prevent flickering of headlamps by delaying driving of one of two condenser fan motors on starting of an air conditioner to prevent sudden descent of voltage of a battery. CONSTITUTION: A circuit includes a first condenser fan relay(31) supplying power of a battery(B+) to a first condenser fan motor(34) to drive; a second condenser fan relay(32) supplying power of the battery to a second condenser fan motor(35) to drive; a full automatic temperature control(FATC:10) supplying power for driving the second condenser fan relay and outputting air conditioner driving signal when an air conditioner switch is turned on; a drier pressure switch(37) turned on and off according to pressure of refrigerant of a drier to supply or intercept power supplied from the FATC to the second condenser fan relay; and an electronic control unit(ECU:20) connecting relay coils(31-1,32-1) of the first condenser fan relay and the second condenser fan relay to grounds to immediately drive the first condenser fan motor when the air conditioner driving signal is input and driving the second condenser fan motor according to condition of the drier pressure switch.

Abstract:
PURPOSE: An air conditioner of a vehicle is provided to improve stability and reliability of diagnosis of a signal line of an air-conditioning sensor by cutting off introduction of ignition power to an air conditioner output end. CONSTITUTION: An air conditioner includes a diagnosis unit(10) self-diagnosing disconnection of a signal line of the air conditioner on ignition; diodes(D1,D2) connected with a power end(VDD) and a ground end(GND) of the diagnosis unit in parallel; and a diode(D3) connected with an output port(OUT) of the diagnosis unit in normal direction to cut off reverse current flowing in through an air conditioner output end on ignition.
