The controller 100 may refer to various control devices that control the operation of various electric loads required for vehicle operation based on various sensors or switching signals installed in the vehicle. For example, the controller 100 may include an airbag control unit (ACU), an anti-loc brake system (ABS), a vehicle stability control (VSC) But it is not limited to at least one of the following systems: IMS, Variable Rack Stroke (VRS), and Air Quality-Control System (AQS).

Although FIG. 1 shows three controllers 110, 120, and 130, the number of the controllers 100 is not limited thereto. In addition, since the configuration and the functional features of the controller 100 described in this specification are common to the first to third controllers 110 to 130, the first controller 110 will be described below.

The first controller 110 may be configured to include a plurality of fuses 112 and a control unit 114.

The plurality of fuses 112 is connected to a power supply (not shown) such as a battery of the vehicle and protects the first controller 110 from overcurrent and overload. The input power source PW_IN1 applied from the power supply unit may be provided to the auxiliary load power supply control module 200 under the control of the control unit 114. [

The control unit 114 can generate the control signal CTR for controlling the operation of the auxiliary load 300 and output the generated control signal CTR to the power control module 200. [

The control signal CTR may be a signal for PWM constant voltage control or dimming control as well as a signal for on / off control of the auxiliary load. That is, unlike the mechanical power supply control using the conventional relays, the vehicle auxiliary power supply control device 10 according to the present invention can actively control various control signals by using a semiconductor switching device.

The control unit 110 may receive the status signal ST related to the failure status of the auxiliary load 300 from the auxiliary load power control module 200 and may determine the status of the auxiliary load 300 The control signal CTR for the operation control of the vehicle control unit 10 can be changed or the failure information can be displayed to notify the driver.

The state signal ST may be a signal indicating a steady state, an open load state, and a short circuit state with respect to the auxiliary load 300. The state signal ST may be a signal indicating an overheated state of the semiconductor switching element 210 included in the auxiliary load power supply control module 200.

The auxiliary load power supply control module 200 is mounted on a center fascia, an engine room and a trunk or the like as shown in Fig. 2 and is connected to the input power source PW_IN1 or PW_IN2 according to a control signal CTR input from the controller 100. [ And outputting them to the various auxiliary loads 300.

The auxiliary load power control module 200 may include a plurality of semiconductor switching elements 210. The auxiliary load power control module 200 may include a plurality of power input / output terminals, a control signal input terminal, and a status signal output terminal for connection and control with a plurality of controllers or various auxiliary loads.

Each semiconductor switching element 210 may be coupled to one auxiliary load 310, 320, 330, or 340.

The semiconductor switching element 210 can monitor the solid state of the connected auxiliary load 300 or the semiconductor switching element 210 itself and when the auxiliary load 300 or the semiconductor switching element 210 is in an abnormal state , And output a preset state signal ST.

For example, the semiconductor switching element 210 may sense a load current applied to the auxiliary load 310 and output a state signal indicative of an open load when the load current is 0 [A]. The semiconductor switching element 210 may sense a load voltage applied to the auxiliary load 320 and may output a state signal indicating a short circuit when the load voltage is 0 [V]. Further, even when the semiconductor switching element 210 itself can not operate due to over-temperature, it is possible to output a corresponding state signal.

The semiconductor switching element 210 can transmit the status signal ST related to the failure state to the controller 100 when a failure occurs in the auxiliary load 300 or the semiconductor switching element 210 itself, It is possible to prevent the breakdown of the auxiliary load 300 and the semiconductor switching element 210 by limiting the current.

The auxiliary load 300 may be an element connected to the auxiliary load power control module 200 and driven according to the output power PW_OUT output from the semiconductor switching element 210 connected thereto.

For example, the auxiliary load 300 may be a motor for driving the air conditioner compressor and the oil pump, or an electric load such as various lamps mounted on the vehicle, various electric components, PTC heater (for heating the vehicle), and the like.

The input switch 400 is connected in parallel between the controller 100 and the auxiliary load power control module 200 and is for fail-safe implementation of the control of the auxiliary load 300. That is, when the controller 100 fails, the auxiliary load 300 can be stably driven by switching the control method of the controller 100 to the direct driving method through the input switch 400. [

The input switch 400 may comprise an ignition key switch or a start button switch for generating a switching signal in accordance with the ignition key of the driver or the operation of the start button.

The switching signal may be at least one of an ST switching signal, an ACC switching signal, an IGN1 switching signal, and an IGN2 switching signal. The ST switching signal is a signal for starting the engine of the vehicle. The ACC switching signal is a signal for operating an electrical product such as audio or radio. The IGN1 switching signal is a signal for switching the fuel circuit, ignition circuit, electronic control, Etc., and the IGN2 switching signal is a signal for operating an equalizer, an air conditioner, a security device, a power window device, and the like.
