Abstract

PURPOSE: A torque control starting method for hybrid electric car is provided to remove a starting motor by starting a car with a main motor and controlling a quantity of torque generation according to a control time in a torque generation. CONSTITUTION: A car is started by using a main motor. A quantity of torque generation is controlled according to a control time in case of a torque generation. A first process generates a maximum torque in an initial starting. A second process decreases a torque in case a rate of a main shaft reaches a specific level in the car. A third process removes an input torque in case the rate of the main shaft reaches a level from 500 to 600 rpm in the car.

하이브리드 전기 자동차용 토크 제어 시동방법{METHOD OF STARTING TORQUE CONTROL FOR HYBRID ELECTRIC VEHICLES}Starting method for torque control for hybrid electric vehicles {METHOD OF STARTING TORQUE CONTROL FOR HYBRID ELECTRIC VEHICLES}

본 발명은 하이브리드 전기 자동차용 토크 제어 시동방법에 관한 것으로서, 보다 상세하게는 시동시 차량의 진동과 소음을 줄이도록 개선된 하이브리드 전기 자동차용 토크 제어 시동방법에 관한 것이다.The present invention relates to a torque control starting method for a hybrid electric vehicle, and more particularly, to a torque control starting method for a hybrid electric vehicle improved to reduce vibration and noise of a vehicle during starting.

현재의 내연기관의 시동방법은 직류 전동기를 이용하여 순간적으로 강력한 토크를 발생시켜 주고, 이 순간적인 토크가 엔진의 크랭크축을 돌려주게 된다. 이때 발생되는 토크는 인입되는 전류의 크기와 따라 결정되는 데 현재는 이를 제어하지 않고 시동 오프(off)되는 시기까지 토크를 발생시켜 크랭킹시 엔진 가속에 의해 오실레이션이 발생하고 높은 오버슈트(overshoot)가 일어난다.The current starting method of the internal combustion engine generates instantaneous powerful torque using a DC motor, and this instantaneous torque turns the crankshaft of the engine. The torque generated at this time is determined by the magnitude of the incoming current, but it generates the torque until the start-off time without controlling it, and oscillation occurs due to engine acceleration during cranking and high overshoot ) Occurs.

이와 같은 종래의 방식은 차량의 크랭킹 순간 많은 진동과 소음을 발생시키고 불필요한 엔진 RPM의 증가를 가져온다.This conventional method generates a lot of vibration and noise at the moment of cranking of the vehicle and leads to an unnecessary increase in engine RPM.

도 1에는 이와 같은 종래의 시동모터의 구동 방식으로, 구동 토크를 순간적으로 인가함으로서 엔진 속도의 변화를 보이고 있다.Figure 1 shows a change in engine speed by applying a driving torque instantaneously in the driving method of such a conventional starter motor.

도시된 바와 같이, 엔진은 순간적으로 오실레이션을 일으키게 되고, 여기서 일정한 속도로 안정화되는 데 시간이 걸린다.As shown, the engine causes oscillation momentarily, where it takes time to stabilize at a constant speed.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창출된 것으로서, 시동시 진동 및 소음의 발생을 줄이고, 불필요한 에너지 소비를 감소시킬 수 있도록 한 하이브리드 전기 자동차용 토크 제어 시동방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a torque controlled starting method for a hybrid electric vehicle that can reduce the occurrence of vibration and noise at the start and reduce unnecessary energy consumption.

도 1은 종래의 시동모터의 구동방식을 나타낸 그래프.1 is a graph showing a driving method of a conventional starting motor.

도 2는 본 발명에 따른 하이브리드 전기 자동차용 토크 제어 시동방법을 나타내 보인 그래프.Figure 2 is a graph showing a torque control starting method for a hybrid electric vehicle according to the present invention.

상기와 같은 목적을 달성하기 위한 본 발명의 하이브리드 전기 자동차용 토크 제어 시동방법은, 차량의 메인모터를 이용하여 상기 차량을 시동시키고, 토크 발생시 이를 제어시간에 따라 토크 발생량을 제어하는 것을 특징으로 한다.Torque control start method for a hybrid electric vehicle of the present invention for achieving the above object, characterized in that for starting the vehicle by using the main motor of the vehicle, when the torque is generated it is characterized in that the torque generated according to the control time .

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에는 하이브리드 전기 자동차용 토크 제어 시동방법에 따른 시동 방식을 그래프로 나타내 보였다.2 is a graph showing a starting method according to the torque control starting method for a hybrid electric vehicle.

도시된 바와 같이, 본 발명에 따른 하이브리드 전기 자동차용 토크 제어 시동방법은, 우선, 차량의 메인모터를 이용하여 차량을 시동시키고, 토크 발생시 이를 제어시간에 따라 토크 발생량을 제어하는 것으로 이루어진다.As shown, the torque control start method for a hybrid electric vehicle according to the present invention comprises, first, starting the vehicle using the main motor of the vehicle, and controlling torque generation amount according to the control time when torque is generated.

상기 토크 발생량 제어는, 우선, 초기 시동시 최대 토크를 발생시킨다.(단계 10)The torque generation amount control first generates a maximum torque during initial startup. (Step 10)

이어서, 상기 단계 10시행 후, 상기 차량의 주축의 속도가 일정 단계에 이르면 토크를 감소시킨다.(단계 20) 여기서, 일정 단계의 상기 주축의 속도는 200∼300rpm 정도이다.Subsequently, after the execution of step 10, the torque is reduced when the speed of the main shaft of the vehicle reaches a predetermined stage. (Step 20) Here, the speed of the main shaft of the predetermined stage is about 200 to 300 rpm.

상기 단계 20시행 후, 상기 주축의 속도가 500∼600rpm 정도에서는 거의 모든 입력 토크를 제거한다.(단계 30)After the step 20, almost all input torque is removed when the speed of the main shaft is about 500 to 600 rpm.

상기한 바와 같이 본 발명에 따른 하이브리드 전기 자동차용 토크 제어 시동방법은, 종래의 차량에 장착되고 있는 시동모터를 제거하고, 차량의 메인모터를 이용하여 시동시킨다.As described above, the torque control starting method for a hybrid electric vehicle according to the present invention removes a starting motor mounted on a conventional vehicle and starts the vehicle using the main motor of the vehicle.

그런 후, 전술한 바와 같이 토크 발생시 이를 제어시간에 따라 그 발생량을 제어한다. 도 2의 그래프는 이와 같은 방식으로 시동시 예상되는 차량 주축의 속도이다.Then, when the torque is generated as described above, the amount of control is controlled according to the control time. The graph of FIG. 2 is the speed of the vehicle spindle which is expected at start-up in this way.

실제 하이브리드 전기 자동차에는 모터로 들어가는 입력 전류를 인버터(inverter)로 제어하고 있고, 또한 주축의 위치 확인을 위하여 위치 센서를 이용하여 모니터링을 하고 있다. 이를 이용 추가적인 시동 프로그램의 설치만으로 토크의 제어가 가능하다.In actual hybrid electric vehicles, the input current entering the motor is controlled by an inverter, and the position sensor is monitored by using a position sensor to check the position of the main shaft. By using this, torque can be controlled by installing an additional startup program.

상술한 바와 같이 본 발명에 따른 하이브리드 전기 자동차용 토크 제어 시동방법은 다음과 같은 효과를 갖는다.As described above, the torque control starting method for a hybrid electric vehicle according to the present invention has the following effects.

시동시 차량의 진동 및 소음이 적고, 시동모터의 제거로 인한 원가절감 및 공정이 감소될 수 있고, 불필요한 에너지 소비를 감소시킬 수 있다.The vibration and noise of the vehicle at the time of starting is low, the cost reduction and the process due to the removal of the starting motor can be reduced, and unnecessary energy consumption can be reduced.

본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 보호범위는 첨부된 특허청구범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
