Abstract
본 발명은 차량의 동작을 제어하는 전자제어기에 안정된 동작 전원을 공급하는 것이다.The present invention is to supply a stable operating power to the electronic controller for controlling the operation of the vehicle.
본 발명은 키 스위치(SW)를 온할 경우에 전원 공급 제어부(1)의 제어에 따라 스위칭 제어부(3)가 스위칭부(2)를 제어하여 배터리(BAT)의 전원을 스위칭하면서 전자 제어기로 출력하고, 전자 제어기로 출력하는 전압을 스위칭 제어부(3)가 판단하며, 판단 결과 미리 설정된 전압 이상일 경우에 스위칭부(2)의 동작을 정지시켜 전자 제어기에 안정된 동작 전원을 공급하며, 스위칭부(2)에서 출력되는 전원을 콘덴서(C1)에 충전시켜 두고, 키 스우치(SW)를 오프하여 스위칭 제어부(3)가 스위칭부(2)를 정지시킬 경우에 콘덴서(C1)에 충전시켜 둔 전원으로 전자 제어기에 계속 동작 전원을 공급하여 콘덴서(C1)에 충전 전원이 방전될 때까지 전자 제어기가 정상으로 동작하게 하며, 필요에 따라 전자 제어기가 출력하는 제어신호에 의해 전원 공급 제어부(1)가 스위칭 제어부(3)를 제어하여 스위칭부(2)가 다시 베터리(BAT)의 전원을 출력 및 전자 제어기에 동작 전원의 공급한다.According to the present invention, when the key switch SW is turned on, the switching control unit 3 controls the switching unit 2 under the control of the power supply control unit 1 to output the power to the electronic controller while switching the power of the battery BAT. The switching controller 3 determines the voltage output to the electronic controller. When the determination result is greater than or equal to the preset voltage, the switching controller 3 stops the operation of the switching unit 2 to supply stable operating power to the electronic controller. The power output from the capacitor is charged to the capacitor C1, and when the switching unit 3 stops the switching unit 2 by turning off the key switch SW, the power is charged to the capacitor C1. Continuously supplying operating power to the controller, the electronic controller operates normally until the charging power is discharged to the capacitor C1, and the power supply control unit 1 controls the switching by a control signal output from the electronic controller as necessary. Controls (3) to the switching unit (2) is supplied to the operating supply power to the back battery (BAT) to the output, and an electronic controller.
