Description

하이브리드 차량의 급가속 제어방법{rapid acceleration control method of a hybrid vehicle}Rapid acceleration control method of a hybrid vehicle

도 1은 본 발명이 적용되는 하이브리드 차량의 파워트레인의 일예를 설명한 도면,1 is a view illustrating an example of a power train of a hybrid vehicle to which the present invention is applied;

도 2는 본 발명의 하이브리드 차량의 급가속 제어방법을 설명한 순서도이다.2 is a flowchart illustrating a rapid acceleration control method of a hybrid vehicle of the present invention.

본 발명은 하이브리드 차량의 급가속 제어방법에 관한 것으로서, 보다 상세하게는 상대적으로 충분한 용량의 모터를 탑재할 수 없는 구조의 하이브리드 파워트레인에서 차량의 급가속시에 운전자의 의지에 보다 부합하는 가속특성을 구현하도록 하는 기술에 관한 것이다.The present invention relates to a method for controlling a rapid acceleration of a hybrid vehicle, and more particularly, in a hybrid powertrain having a structure in which a motor having a relatively large capacity cannot be mounted, acceleration characteristics that are more in line with a driver's will during a rapid acceleration of a vehicle. It relates to a technique to implement.

도 1은 본 발명이 적용될 수 있는 형식의 하이브리드 파워트레인을 도시하고 있는바, 엔진(500)은 토크컨버터(502)의 임펠러에 연결되어 있고 토크컨버터(502)의 터빈은 클러치(504)를 통해 변속기(506)의 입력축에 연결되어 있으며, 변속기(506)의 입력축에는 변속기(506)와 토크컨버터(502) 사이의 위치에 모터(508)가 장착되어 있는 구조이다.1 shows a hybrid powertrain of the type to which the present invention can be applied, in which an engine 500 is connected to an impeller of a torque converter 502 and a turbine of the torque converter 502 is connected via a clutch 504. It is connected to the input shaft of the transmission 506, the motor 508 is mounted on the input shaft of the transmission 506 at a position between the transmission 506 and the torque converter 502.

상기한 바와 같은 하이브리드 파워트레인 구조에서는 상기 변속기(506)를 종래의 자동변속기나 CVT로 사용할 수 있으나, 차량에의 탑재성을 고려하면 상기 모터(508)의 크기를 크게 설정하기 어려운 문제점이 있다.In the hybrid powertrain structure as described above, the transmission 506 can be used as a conventional automatic transmission or CVT. However, considering the mountability of the vehicle, it is difficult to set the size of the motor 508 large.

따라서 모터(508)의 용량을 충분히 확보할 수 있는 다른 하드타입(hard type) 하이브리드 파워트레인에 비하여, 모터(508)의 출력이 상대적으로 떨어져서 차량의 급가속시에 엔진(500)의 출력에 모터(508)의 출력을 더하여 급가속에 대응하는 것에 한계가 있게 된다.Therefore, as compared to other hard type hybrid powertrains capable of sufficiently securing the capacity of the motor 508, the output of the motor 508 is relatively lowered, so that the motor is output to the output of the engine 500 during rapid acceleration of the vehicle. Adding the output of 508, there is a limit to responding to rapid acceleration.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 종래의 일반적인 자동변속기나 CVT 등을 거의 변경 없이 채용하여 차량에의 탑재성을 고려하면 모터의 용량의 크게 설정할 수 없는 구성의 하이브리드 파워트레인을 탑재한 차량이 운전자의 급가속 요구에 대응하여, 보다 향상된 급가속 성능을 발휘할 수 있도록 한 하이브리드 차량의 급가속 제어방법을 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and adopts a conventional general automatic transmission or CVT with almost no change, and considering the mountability in the vehicle, the hybrid power of the configuration that cannot be set large in capacity of the motor It is an object of the present invention to provide a rapid acceleration control method for a hybrid vehicle in which a train-mounted vehicle can exhibit an improved rapid acceleration performance in response to a driver's rapid acceleration demand.

이하, 첨부된 도 2를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying Figure 2 describes a preferred embodiment of the present invention.

본 발명은 도 1에 도시된 바와 같이 엔진의 출력축이 토크컨버터를 포함하는 변속기에 클러치를 통해 연결되고, 상기 변속기에는 모터가 연결된 하이브리드 차량에 적용되는 것으로서, 운전자의 급가속 의지를 판단하는 단계와; 운전자의 급가속 의지가 판단되면 차량이 정차 상태인지 전기차모드로 주행중인지 판단하는 단계와; 차량이 정차 상태인 경우 상기 클러치를 체결함과 동시에 엔진을 시동시키는 단계를 수행하고,차량이 전기차모드로 주행중인 경우 모터와 엔진 모두에 의한 구동모드인 하이브리드모드로의 전환을 기존에 설정되어 있는 차속보다 낮은 차속에서 수행하는 단계를 포함하여 구성된다.As shown in FIG. 1, an output shaft of an engine is connected to a transmission including a torque converter via a clutch, and the transmission is applied to a hybrid vehicle to which a motor is connected. ; Determining whether the vehicle is in a stopped state or driving in an electric vehicle mode when it is determined that the driver is willing to accelerate; When the vehicle is in a stopped state, the engine is started at the same time as the clutch is engaged. When the vehicle is running in the electric vehicle mode, the switchover to the hybrid mode, which is a driving mode by both the motor and the engine, is previously set. And performing at a vehicle speed lower than the vehicle speed.

상기 토크컨버터를 포함하는 변속기란 종래의 일반적인 자동변속기나 CVT를 통칭하는 의미이다.The transmission including the torque converter refers to a conventional general automatic transmission or CVT.

본 발명을 적용하기 위해서는 운전석 근처의 위치, 바람직하게는 쉬프트레버 근처에 상기 스포츠모드스위치를 별도로 추가하고, 이를 조작하는지의 여부에 의해 운전자의 급가속 의지를 확실하게 확인할 수 있도록 한다.In order to apply the present invention, the sports mode switch is separately added to a position near the driver's seat, preferably a shift lever, and the driver's sudden acceleration will be reliably determined by whether or not to operate it.

즉, 상기 운전자의 급가속 의지를 판단하는 단계는 운전석에 설치된 스포츠모드스위치의 조작상태를 파악하는 단계와; 상기 스포츠모드스위치가 온된 상태에서 스로틀개도의 변화율에 의해 급가속 상태를 판단하는 단계로 이루어져서, 운전자가 상기 스포츠모드스위치를 조작한 후 가속페달을 급격히 밟는 경우만을 본 발명의 제어가 수행되는 조건으로 설정한 것이다.That is, the step of determining the sudden acceleration of the driver is to grasp the operation state of the sport mode switch installed in the driver's seat; The step of determining the rapid acceleration state by the rate of change of the throttle opening degree in the state that the sport mode switch is turned on, the condition that the control of the present invention is performed only when the driver presses the accelerator pedal sharply after operating the sport mode switch It is set.

상기 스로틀개도의 변화율에 의해 급가속 상태를 판단하는 단계는 스로틀밸브에 설치된 스로틀포지션센서의 개도 변화율에 따라 판단할 수 있다. 물론, 이외에 가속페달에 설치된 가속페달센서의 신호로부터 판단할 수도 있고, 상기와 같은 가속페달센서의 신호나 스로트포지션센서의 신호를 받아 스로틀밸브를 전자적으로 제어하는 전자스로틀컨트롤러로부터 제공되는 신호를 이용하여 간접적으로 판단할 수도 있다.The step of determining the rapid acceleration state based on the change rate of the throttle opening degree may be determined according to the change rate of the opening degree of the throttle position sensor installed in the throttle valve. Of course, it can be determined from the signal of the accelerator pedal sensor installed in the accelerator pedal, the signal provided from the electronic throttle controller for controlling the throttle valve electronically by receiving the signal of the accelerator pedal sensor or the signal of the throat position sensor as described above. Indirect judgment can also be used.

하이브리드 파워트레인을 제어하는 컨트롤러는 상기한 바와 같이 스포츠모드스위치가 온되고 스로틀개도의 변화율에 의해 운전자의 급가속 의지가 판단되면, 차량이 정차해 있던 경우라면, 종래의 전기차모드의 출발 및 저속 운행을 실시하지 않고 그대로 엔진을 시동시키고 클러치를 연결하여, 엔진에 의한 신속한 가속성능을 구현하도록 한다.As described above, the controller for controlling the hybrid powertrain starts and slows the operation of the conventional electric vehicle mode when the vehicle is stopped when the sport mode switch is turned on and the driver's intention to accelerate is determined by the rate of change of the throttle opening. By starting the engine as it is without performing the clutch and connecting the clutch, to achieve the rapid acceleration performance by the engine.

차량이 이미 전기차모드로 주행하고 있던 중에 상기한 바와 같이 스포츠모 드스위치가 작동되고 스로틀개도의 변화율에 의해 운전자의 급가속 의지가 판단되면, 상술한 바와 같이 종래에 이미 설정되어 있던 것보다 낮은 차속에서도 즉시 엔진을 시동시키고 클러치를 연결하여 엔진의 구동력이 구동륜으로 제공될 수 있도록 함으로써, 가속성능을 향상시키도록 한다.If the sports mode switch is operated as described above and the driver's willingness to accelerate is determined by the rate of change of the throttle opening as described above while the vehicle is already running in the electric vehicle mode, the vehicle having a lower speed than previously set as described above. Even in the midst of starting the engine and connecting the clutch so that the driving force of the engine can be provided to the drive wheels, thereby improving the acceleration performance.

참고로 도 2에는 ISG(Integrated Starter Generator)가 엔진에 장착되어 있는 경우를 도시하고 있는바, 이때에는 컨트롤러가 상기한 바와 같이 운전자의 급가속 의지가 판단되면, 상기 ISG를 종래의 일반적인 전기차모드에서 엔진과 모터에 의한 하이브리드모드로 전환하도록 설정되어 있는 차속보다 낮은 차속에서 ISG를 기동하여 엔진을 시동시키고 클러치를 연결하여 엔진에서 발생된 동력으로 차량의 가속성능을 향상시키도록 한다.For reference, FIG. 2 illustrates a case in which an integrated starter generator (ISG) is mounted on an engine. In this case, when the controller determines the driver's willingness to accelerate as described above, the ISG is controlled in a conventional electric vehicle mode. The ISG is started at a vehicle speed lower than the vehicle speed set to the hybrid mode by the engine and the motor to start the engine, and the clutch is connected to improve the acceleration performance of the vehicle by the power generated by the engine.

즉, 본 발명은 종래에 일반적인 조건이었다면 보다 나중에 엔진과 모터에 의한 하이브리드모드로 전환했었을 상황에서, 운전자의 급가속 의지를 최대한 반영하기 위하여 상대적으로 보다 이른 시점에 엔진을 시동시키고, 엔진을 동력을 클러치를 통해 구동륜으로 전달할 수 있는 상태로 전환함으로써, 운전자의 급가속 의지에 보다 부합할 수 있는 차량의 구동특성을 제공하도록 하는 것이다.That is, the present invention starts the engine at a relatively earlier time in order to reflect the driver's willingness to accelerate as much as possible in the situation where the conventional condition was to switch to the hybrid mode by the engine and the motor later. By switching to the state that can be transmitted to the driving wheel through the clutch, to provide the driving characteristics of the vehicle that can more closely match the driver's rapid acceleration.

이상과 같이 본 발명에 의하면, 종래의 일반적인 자동변속기나 CVT 등을 거의 변경 없이 채용하여 차량에의 탑재성을 고려하면 모터의 용량의 크게 설정할 수 없는 구성의 하이브리드 파워트레인을 탑재한 차량이 운전자의 급가속 요구에 대응하여, 보다 향상된 급가속 성능을 발휘할 수 있도록 한다.As described above, according to the present invention, a vehicle equipped with a hybrid power train having a configuration in which the capacity of the motor cannot be largely set in consideration of the mountability to the vehicle by adopting a conventional general automatic transmission or CVT with almost no change is made. In response to the rapid acceleration demand, it is possible to exhibit improved rapid acceleration performance.
