And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.
도 1을 참조하여 본 발명의 실시예에 따른 차량의 전원 제어 시스템 구성을 설명한다.A configuration of a power control system for a vehicle according to an exemplary embodiment of the present invention will be described with reference to FIG. 1.
본 발명의 실시예는 서로 다른 전원용량을 갖는 제1, 제2 배터리(100, 110)를 가지며, 전장품의 부하에 따라 해당되는 전원을 공급하는 차량의 전원 제어 시스템에 있어서, 차량의 엔진 회전수를 검출하는 엔진 회전수 검출센서, 차량의 에어컨 구동에 관련된 스위칭 상태를 검출하는 에어컨 스위치, 제어부(120), 전동식 에어컨 컴프레서(130)를 포함하여 구성한다.In an embodiment of the present invention, in a vehicle power control system having first and second batteries 100 and 110 having different power supply capacities and supplying corresponding power according to loads of electrical appliances, engine speed of the vehicle It comprises an engine speed detection sensor for detecting the air conditioner switch for detecting a switching state associated with the air conditioner driving of the vehicle, the control unit 120, the electric air conditioner compressor 130.
한편, 본 발명의 실시예는 차량의 운전 조건에 따라 발전기와 시동 전동기의 기능을 하는 발전 기동기(140)(IGS ; Integrated Generator Starter)와; 발전 기동기(140)와 제1, 제2 배터리(100, 110)의 사이에 장착되어 전류를 변환시키는 인버터(150)(Inverter)와; 제1, 제2 배터리(100, 110)간의 전압을 변환시키는 직류/직류 컨버터(160)(DC/DC Converter)와; 차량의 엔진 초기 기동을 하는 시동 전동기를 더 포함하여 구성한다.On the other hand, an embodiment of the present invention is a generator starter 140 (IGS; Integrated Generator Starter) that functions as a generator and a starting motor according to the driving conditions of the vehicle; An inverter 150 mounted between the power generation starter 140 and the first and second batteries 100 and 110 to convert current; A DC / DC converter 160 for converting voltages between the first and second batteries 100 and 110; It further comprises a starting motor for initial engine start of the vehicle.
제1, 제2 배터리(100, 110)는 각각 12V, 36V의 전원용량을 가지며, 상기 차량에는 적어도 한 개 이상의 42V화 전장품이 장착된다.The first and second batteries 100 and 110 have power supply capacities of 12V and 36V, respectively, and at least one 42V electrical equipment is mounted in the vehicle.
예를 들어, 42V화 부품은 벨트식 발전 기동기(BIGS ; Belt-driven Integrated Generator Starter), 42V 전용 전동식 에어컨 컴프레서(130), 라디에이터 팬, 콘덴서 팬 모터 등이 있다.For example, 42V parts include a belt-driven integrated generator starter (BIGS), an electric air conditioner compressor 130 dedicated to 42V, a radiator fan, a condenser fan motor, and the like.
제어부(120)는 각각의 센서들로부터 입력되는 신호를 분석하여 차량의 엔진이 정지된 상태에서 에어컨 스위치가 온(ON)되면 에어컨 구동 제어신호를 발생한다.The controller 120 analyzes signals input from the respective sensors and generates an air conditioner driving control signal when the air conditioner switch is turned on while the engine of the vehicle is stopped.
또한, 제어부(120)는 차량의 엔진이 시동된 상태에서 아이들 스톱(Idle Stop) 기능 시 엔진을 정지시키도록 제어하며, 아이들 스톱(Idle Stop) 기능에 따라 엔진이 정지된 상태에서 재시동 시 발전 기동기(140)(IGS)를 시동 전동기로 동작하도록 제어한다.In addition, the control unit 120 controls the engine to stop when the idle stop function is performed while the engine of the vehicle is started, and the power generation starter when the engine is restarted while the engine is stopped according to the idle stop function. 140 (IGS) is controlled to operate as a starting motor.
그리고, 제어부(120)는 재시동된 엔진의 정상 운전 시 발전 기동기(140) (IGS)를 발전기로 동작하도록 제어한다.In addition, the controller 120 controls the power generator 140 (IGS) to operate as a generator during normal operation of the restarted engine.
전동식 에어컨 컴프레서(130)는 제어부(120)로부터 공급되는 에어컨 구동 제어신호의 입력에 따라 구동된다.The electric air conditioner compressor 130 is driven according to the input of the air conditioner driving control signal supplied from the controller 120.
전동식 에어컨 컴프레서(130)는 제2 배터리(110)로부터 36V의 전원을 공급받아 구동되는 모터를 내장한다.The electric air conditioner compressor 130 includes a motor driven by receiving 36 V of power from the second battery 110.
전동식 에어컨 컴프레서(130)를 사용함에 따라 기계식 에어컨 컴프레서 보다 높은 효율을 가지며, 이로 인해 연비를 개선할 수 있다.(약 3%)By using the electric air conditioner compressor 130 has a higher efficiency than the mechanical air conditioner compressor, thereby improving fuel economy. (About 3%)
본 발명의 실시예에 따른 발전 기동기(140)(IGS)는 아이들 스톱 & 고(Idle Stop & Go) 기능 수행시 엔진을 재시동시키고, 정상 동작시에는 발전기로만 사용하도록 제어된다.The power generation starter 140 (IGS) according to the embodiment of the present invention is controlled to restart the engine when the idle stop & go function is performed, and to use only the generator in normal operation.
본 발명의 실시예는 아이들 스톱 & 고(Idle Stop & Go)기능에 의해 엔진이 정지하고 있는 상황에서, 제2 배터리(110)(36V 배터리)의 배터리 충전상태(SOC ; State Of Charge)가 충분한 조건에서, 운전자가 에어컨 스위치를 온(ON)시켰을 때전동식 에어컨 컴프레서(130)에 내장된 모터에 의해 전동식 에어컨 컴프레서(130)를 구동시키는 것이다.According to an exemplary embodiment of the present invention, the state of charge (SOC) of the second battery 110 (36V battery) is sufficient when the engine is stopped by the idle stop & go function. In the condition, when the driver turns on the air conditioner switch, the electric air conditioner compressor 130 is driven by a motor built in the electric air conditioner compressor 130.
여기서, 아이들 스톱 & 고(Idle Stop & Go) 기능이라 함은 차량이 장시간 신호등 등에 의해 정지한 경우, 배기가스와 연비를 향상시키기 위해 엔진을 정지시키고, 운전자가 다시 엑셀레이터 페달을 밟은 경우 엔진을 재시동 시켜 주행을 하는 기능을 말한다.Here, the Idle Stop & Go function means to stop the engine to improve the exhaust gas and fuel efficiency when the vehicle is stopped for a long time by a traffic light or the like, and restart the engine when the driver presses the accelerator pedal again. It is a function to drive.
도 1과 도 2를 참조하여 본 발명의 실시예에 따른 차량의 전원 제어 시스템 동작을 설명한다.1 and 2 will be described the operation of the power control system of a vehicle according to an embodiment of the present invention.
먼저, 시동 전동기가 구동되어 엔진이 초기 기동된 상태를 가정하여 엔진이 회전되는 상태에서, 아이들 스톱(Idle Stop) 기능 시 제어부(120)는 엔진의 회전을 정지시키는 제어동작을 수행한다.First, in a state in which the engine is rotated on the assumption that the starting motor is driven and the engine is initially started, the controller 120 performs a control operation to stop the rotation of the engine when the idle stop function is performed.
이때, 에어컨 스위치가 온(ON)되면, 전동식 에어컨 컴프레서(130)에 내장되는 모터는 제2 배터리(110)(36V 배터리)로부터 전원을 공급받아 구동된다.At this time, when the air conditioner switch is ON, the motor built in the electric air conditioner compressor 130 is driven by receiving power from the second battery 110 (36V battery).
모터의 구동에 따라 전동식 에어컨 컴프레서(130)가 동작되며, 엔진이 정지된 상태에서도 에어컨 기능을 사용할 수 있게 된다.The electric air conditioner compressor 130 is operated according to the driving of the motor, and the air conditioner function can be used even when the engine is stopped.
한편, 아이들 스톱(Idle Stop) 기능에 따라 엔진이 정지된 상태에서 재시동 시 본 발명의 실시예에서는 시동 전동기를 구동시키지 않고 대신 발전 기동기(140) (IGS)가 시동 전동기 기능을 하여 엔진을 시동시킨다.Meanwhile, in the embodiment of the present invention, when the engine is restarted in the stopped state according to the idle stop function, the power generator 140 (IGS) functions as a starting motor to start the engine instead of driving the starting motor. .
상기한 바와 같이 엔진이 정상적으로 운전되면, 발전 기동기(140)(IGS)는 발전기로 동작한다.When the engine is normally operated as described above, the power generation starter 140 (IGS) operates as a generator.
예를 들어, 상기 차량의 주행시 제어부(120)는 배터리 충전량(SOC)을 검출하고 부족 충전일 경우 발전 기동기(140)(IGS)를 발전 모드로 변환시켜 배터리를 충전하고, 상기 차량의 감속 또는 제동 시에는 발전 기동기(140)(IGS)가 회생 제동 모드로 동작하도록 제어동작을 수행한다.For example, when driving the vehicle, the control unit 120 detects the battery charge amount SOC and converts the generator starter 140 (IGS) to the power generation mode to charge the battery when the battery is undercharged, and decelerates or brakes the vehicle. In operation, the generator starter 140 (IGS) performs a control operation to operate in the regenerative braking mode.
상술한 바와 같이 본 발명에 따른 차량의 전원 제어 시스템은 42V 전원 시스템을 도입하여 차량의 운전 상태에 따라 선택적으로 전원 공급을 제어하여 불필요한 엔진 시동을 방지함으로써 연비향상 및 배기 가스 저감을 도모할 수 있다.As described above, the vehicle power control system according to the present invention adopts a 42V power system to selectively control the power supply according to the driving state of the vehicle to prevent unnecessary engine starting, thereby improving fuel economy and reducing exhaust gas. .
또한, 일반적인 차량에서 배터리 충전기능을 하는 발전기를 삭제할 수 있으며, 동일 파워 대비 14V 계에 비해 약 10% 정도의 와이어 하네스(Wire Harness)를 경량화할 수 있는 효과가 있다.In addition, it is possible to delete a generator that charges the battery in a general vehicle, and the weight of about 10% of the wire harness (Wire Harness) can be reduced compared to the 14V system compared to the same power.
