The inverter 150 is connected in series between the motor 110 and the first battery 130. When the operation mode of the first motor 110 is the drive mode, the inverter 150 converts the voltage of the first battery 130 to AC (Regenerative mode), the voltage generated from the motor 110 is converted to DC to charge the first battery 130 .

컨버터(160)는 제 2 배터리(140) 와 제 1 배터리(130) 사이에 병렬로 연결되며, 모터(110)의 동작모드에 따라, 승압모드(Boost) 또는 강압모드(Buck)로 동작할 수 있다. 즉, 제 2 배터리(140)의 전압을 승압하여, 제 1 배터리(130)를 충전할 수 있으며, 반대로 제 1 배터리(130)의 전압을 강압하여 제 2 배터리(140)를 충전할 수 있다. 따라서 이러한 승압(BOOST)모드를 이용하여 제 1 모터(110)에 공급하는 구동전력을 보충할 수 있으며 강압(BUCK)모드를 이용하여 차량의 전장에 공급하는 구동전력을 제어할 수 있다. 컨버터(160)는 양방향 DC - DC 컨버터(160)일 수 있다.
The converter 160 is connected in parallel between the second battery 140 and the first battery 130 and may operate in a boost mode or a buck mode according to an operation mode of the motor 110 have. That is, the voltage of the second battery 140 can be boosted to charge the first battery 130, and conversely, the voltage of the first battery 130 can be lowered to charge the second battery 140. Therefore, the driving power supplied to the first motor 110 can be supplemented by using the boost mode, and the driving power supplied to the vehicle's entire length can be controlled using the BUCK mode. The converter 160 may be a bi-directional DC-DC converter 160.

자동차 외부 온도가 낮거나 차량 내의 암전류가 발생하는 경우등을 포함한 다양한 원인으로 인하여, 제 2 배터리(140)는 방전될 수 있다. 엔진(100)에 시동을 거는 제 2 모터(120)는 제 2 배터리(140)로부터 구동전력을 공급받기 때문에 제 2 배터리(140)가 방전되면, 엔진(100)의 시동이 불가능한 상황이 발생할 수 있다.The second battery 140 may be discharged due to various causes including a low temperature outside the vehicle, a dark current in the vehicle, and the like. Since the second motor 120 that starts the engine 100 is supplied with the driving power from the second battery 140, when the second battery 140 is discharged, a situation may occur in which the engine 100 can not be started have.

따라서 시동이 불가능한 상황을 방지하기 위하여 컨트롤러(170)는 제 2 배터리(140)의 상태를 기초로, 제 2 모터(120)에 의해 상기 엔진(100)이 시동되는 엔진시동모드 및 상기 제1 모터(110)의 출력을 이용하여 차량이 초기기동되는 모터기동모드를 수행한다. 또한 컨트롤러(170)는 자동차의 엔진(100), ABS등을 제어하는 ECU(electronic control unit)일 수 있다.Therefore, in order to prevent the situation where the engine 100 is started, the controller 170 controls the engine start mode in which the engine 100 is started by the second motor 120, The motor start mode in which the vehicle is initially started is performed using the output of the motor 110. [ Further, the controller 170 may be an electronic control unit (ECU) for controlling the engine 100 of the vehicle, the ABS, and the like.

컨트롤러(170)에 대해 자세히 설명하면, 컨트롤러(170)는 제 2 배터리(140)의 상태를 확인하기 위하여, 제 2 배터리(140)의 전압 , 전류, SOC(state of charge)에 대한 정보를 제 2 배터리(140)에 구비된 센서를 통해 전달받는다. 전달받은 제2 배터리의 상태를 기초로 컨트롤러(170)는 제 2 모터(120)에 공급해야하는 구동전력이 제 2 배터리(140)에 충전되어 있는지 확인하며, 이를 위하여 컨트롤러(170)는 제 2 배터리(140)의 전압을 기 설정된 임계치와 비교할 수 있다. 여기서 임계치는 제 2 모터(120)가 구동하기 위한 구동전력에 따라 설정될 수 있다. 또한, 반드시 제 2 배터리(140)의 전압을 기준으로 판단해야하는 것은 아니며, 제 2 배터리(140)의 전류, SOC 또는 이들의 조합을 통하여 제 2 모터(120)의 구동전력이 충전되어 있는지 여부를 판단할 수 있다.In order to check the state of the second battery 140, the controller 170 sets information on the voltage, current, and SOC (state of charge) of the second battery 140 2 battery 140 via a sensor. The controller 170 determines whether the driving power to be supplied to the second motor 120 is charged in the second battery 140 based on the received state of the second battery. It is possible to compare the voltage of the transistor 140 with a predetermined threshold value. Here, the threshold value may be set according to the driving power for driving the second motor 120. [ Also, it is not necessarily determined based on the voltage of the second battery 140, and it is determined whether or not the driving power of the second motor 120 is charged through the current, the SOC, or a combination thereof of the second battery 140 It can be judged.

제 2 배터리(140)의 전압값이 임계치에 미만인 경우, 컨트롤러(170)는 제 2 배터리(140)의 전압이 충전되도록 제 1 배터리(130)의 전압을 강압시키는 강압신호를 생성하여 컨버터(160)에 인가한다. 제 1 배터리(130)와 제 2 배터리(140)는 컨버터(160)를 통해 양방향으로 전력을 전달할 수 있으므로, 제 2 배터리(140)의 부족한 전력을 제 1 배터리(130)의 전력을 이용하여 충전할 수 있다.When the voltage value of the second battery 140 is less than the threshold value, the controller 170 generates a step-down signal for stepping down the voltage of the first battery 130 to charge the voltage of the second battery 140, . The first battery 130 and the second battery 140 can transmit electric power in both directions through the converter 160 so that the insufficient electric power of the second battery 140 can be charged by using the electric power of the first battery 130 can do.

일정시간 동안에 제 2 배터리(140)를 제 1 배터리(130)와 컨버터(160)를 이용하여 충전한 뒤, 컨트롤러(170)는 충전된 제 2 배터리(140)의 상태를 다시 한번 확인한다. 상술한 바와 같이 컨트롤러(170)는 제 2 배터리(140)의 전압값을 임계치와 비교함으로써 충전된 제 2 배터리(140)의 상태를 확인할 수 있다.After charging the second battery 140 using the first battery 130 and the converter 160 for a predetermined period of time, the controller 170 once again confirms the state of the charged second battery 140. As described above, the controller 170 can check the state of the charged second battery 140 by comparing the voltage value of the second battery 140 with a threshold value.

충전한 제 2 배터리(140)의 전압값이 임계치 이상인 경우, 컨트롤러(170)는 제 2 배터리(140)로부터 구동전력을 공급받은 제 2 모터(120)가 엔진(100)을 시동시키도록 제어한다. 이를 위하여 컨트롤러(170)는 엔진(100)의 시동을 위한 시동신호를 제 2 모터(120)에 인가한다.When the charged voltage of the second battery 140 is equal to or higher than the threshold value, the controller 170 controls the second motor 120, which receives the driving power from the second battery 140, to start the engine 100 . The controller 170 applies a start signal for starting the engine 100 to the second motor 120 for this purpose.

충전한 제 2 배터리(140)의 전압값이 임계치 미만인 경우, 컨트롤러(170)는 제 1 배터리(130)의 전압을 AC전압으로 변환하는 변환신호를 생성하고 인버터(150)에 인가하여 모터기동모드를 수행한다. 이 경우, 제 2 배터리(140)에 제 2 모터(120)의 구동전력이 충전되어 있지 않아 제2 모터(120)가 구동될 수 없으므로, 제 1 모터(110)의 출력에 의해 차량이 초기기동된다.The controller 170 generates a conversion signal for converting the voltage of the first battery 130 into an AC voltage and applies the converted signal to the inverter 150 to generate a motor start mode . In this case, since the driving power of the second motor 120 is not charged to the second battery 140, the second motor 120 can not be driven, do.

모터기동모드에 대해 구체적으로 설명하면, 컨트롤러(170)는 제 1 배터리(130)의 전압을 AC전압으로 변환하라는 변환신호를 생성하여 인버터(150)에 인가한다. 인버터(150)는 변환신호에 따라 제 1 배터리(130)의 전압을 변환하여 제 1 모터(110)에 전달하게 되며, 제 1 모터(110)를 구동하기 시작하고 차량은 기동한다. 이 때 제 1 모터(110)의 출력은 도1 의 벨트를 통해 엔진(100)으로 전달되고 이로 인하여 엔진(100)은 시동된다.Specifically, the controller 170 generates a conversion signal to convert the voltage of the first battery 130 to an AC voltage and applies the conversion signal to the inverter 150. [ The inverter 150 converts the voltage of the first battery 130 according to the conversion signal and transmits the voltage to the first motor 110. The inverter 150 starts to drive the first motor 110 and the vehicle starts. At this time, the output of the first motor 110 is transmitted to the engine 100 via the belt shown in FIG. 1, whereby the engine 100 is started.

도 2 는 변환신호와 엔진(100)의 출력 변화를 나타낸 그래프로서, 1번 그래프는 변환신호를 의미하면, 2번 그래프는 엔진(100)의 출력변화를 나타낸다. 도 2에 도시된 바와 같이 a 구간에서 인버터(150)에 변환신호가 인가되면, 엔진(100)은 소정의 딜레이타임(delay time)을 가지면서 출력이 증가된다. 변환신호가 종료되는 a구간 이후에는 엔진(100)은 850rpm근방의 출력을 가지면서 안정적으로 구동된다.
FIG. 2 is a graph showing the conversion signal and the output variation of the engine 100. When the first graph indicates the conversion signal, the second graph indicates the output variation of the engine 100. FIG. As shown in FIG. 2, when a conversion signal is applied to the inverter 150 in the interval a, the engine 100 increases its output with a predetermined delay time. After the period a in which the conversion signal ends, the engine 100 is driven stably while having an output in the vicinity of 850 rpm.

본 발명의 일실시예에 따른 하이브리드 자동차의 시동장치는 낮은 기온이나 암전류등에 의해 제 2 배터리(140)가 방전되는 경우 엔진(100)의 시동이 불가능한 상황을 방지하기 위한 것이다. 본 발명의 일실시예는 제 2 배터리(140)가 방전시 제 1 배터리(130)의 전압을 이용하여 제 2 배터리(140)를 충전하며, 충전된 제 2 배터리(140)가 제 2 모터(120)를 구동시킬 수 없는 경우에는 제 1 배터리(130)와 제 1 모터(110)를 이용하여 자동차를 초기기동시킨다.
The starting device of the hybrid vehicle according to an embodiment of the present invention is for preventing the engine 100 from being started when the second battery 140 is discharged due to a low temperature or a dark current. In an embodiment of the present invention, when the second battery 140 discharges, the second battery 140 is charged using the voltage of the first battery 130, and the charged second battery 140 is charged to the second motor 140 120 can not be driven, the vehicle is initially started using the first battery 130 and the first motor 110.

이하에서는, 상기한 바와 같은 구성을 포함하는 본 발명의 일 실시예에 따른 하이브리드 자동차 시동방법을 도 3을 참고하여 설명한다. 이하의 설명 중, 상기에서 설명된 내용과 동일하거나 유사한 설명은 생략되거나 또는 간단히 설명된다.
Hereinafter, a method of starting a hybrid vehicle according to an embodiment of the present invention including the above-described configuration will be described with reference to FIG. In the following description, the same or similar descriptions as those described above are omitted or briefly described.

본 발명의 일실시예에 따른 하이브리드 자동차의 시동방법은 제 2 배터리(140)의 상태에 기초하여, 제 2 배터리(140)의 충전여부와 제2 모터에 의한 엔진(100)시동여부를 결정하는 엔진시동모드단계 및 충전된 상기 제 2 배터리(140)의 전압값이 기 설정된 임계치 미만인 경우 제1 모터의 출력을 이용하여 차량이 초기기동되는 모터기동모드 단계를 포함한다.,
The method for starting the hybrid vehicle according to an embodiment of the present invention determines whether the second battery 140 is charged and whether the engine 100 is started by the second motor 140 based on the state of the second battery 140 And a motor startup mode in which the vehicle is initially started using the output of the first motor when the engine startup mode and the charged voltage of the second battery 140 are less than a predetermined threshold value.

엔진시동모드단계를 자세히 설명하면 제 2 배터리(140)의 상태를 확인하기 위하여 제 2 배터리(140)의 전압값을 임계치와 비교한다. 제 2 배터리(140)의 전압값이 임계치에 보다 작은 경우 즉,미만인 경우, 제 2 배터리(140)를 충전한다.The engine start mode step will be described in detail. In order to confirm the state of the second battery 140, the voltage value of the second battery 140 is compared with a threshold value. If the voltage value of the second battery 140 is less than or equal to the threshold value, the second battery 140 is charged.

이때, 제 2 배터리(140)를 충전하기 위하여, 제 1 배터리(130)의 전압을 컨버터(160)를 이용하여 강압하여 제 2 배터리(140)를 일정시간 동안 충전한다. 본 발명의 일실시예에 포함된 컨버터(160)는 양방향 DC-DC컨버터(160)일 수 있으므로, 제 1 배터리(130)의 전압을 낮추어 제 2 배터리(140)에 전달할 수 있다.At this time, in order to charge the second battery 140, the voltage of the first battery 130 is lowered by using the converter 160 to charge the second battery 140 for a predetermined time. The converter 160 included in the embodiment of the present invention may be a bi-directional DC-DC converter 160, so that the voltage of the first battery 130 may be lowered to the second battery 140.

충전된 제 2 배터리(140)의 전압값이 임계치 이상인 경우, 제 2 배터리(140)에 제 2 모터(120)의 구동전력이 충전된 것으로 보아 제 2 모터(120)를 구동시킨다. 다시 말해,제 2 모터(120)에 구동전력을 공급하여 제2 모터에 의해 엔진(100)을 시동시킨다. When the voltage value of the charged second battery 140 is equal to or higher than the threshold value, the second motor 120 is driven by the driving power of the second motor 120 being charged in the second battery 140. In other words, the second motor 120 is supplied with drive power and the engine 100 is started by the second motor.

그러나 충전된 제 2 배터리(140)의 전압이 임계치 미만인 경우, 제 1 모터(110)의 출력을 이용하여 차량을 초기 기동시킨다. 이를 위해 제 1 배터리(130)의 DC전압을 인버터(150)를 통해 AC전압으로 변환한 다음, AC전압으로 변환된 제 1 배터리(130)의 전압을 제 1 모터(110)에 인가함으로써 제 1 모터(110)를 구동시킨다. 제 1 모터(110)의 구동으로 인하여 차량은 기동하게 되며, 제 1 모터(110)의 출력은 벨트를 통해 엔진(100)에 전달된다. 엔진(100)은 제 1 모터(110)의 출력에 의하여 시동이 걸리게 된다.
However, when the voltage of the charged second battery 140 is less than the threshold value, the vehicle is initially started using the output of the first motor 110. [ The DC voltage of the first battery 130 is converted into the AC voltage through the inverter 150 and the voltage of the first battery 130 converted into the AC voltage is applied to the first motor 110, And drives the motor 110. The first motor 110 drives the vehicle and the output of the first motor 110 is transmitted to the engine 100 through the belt. The engine 100 is started by the output of the first motor 110.

본 발명의 일실시예에 따른 하이브리드 자동차의 시동방법은 다양한 원인으로 인하여 제 2 배터리(140)가 방전되는 경우 차량의 시동을 걸기위한 것으로 제 2 배터리(140)의 충전과 제 1 모터(110)에 의한 초기기동으로 엔진(100)을 시동걸 수 있다.
The method for starting the hybrid vehicle according to an embodiment of the present invention is for starting the vehicle when the second battery 140 is discharged due to various reasons and the charging of the second battery 140 and the charging of the first motor 110, The engine 100 can be started by the initial start of the engine.
