AMT차량의 변속제어방법{SHIFT CONTROL METHOD FOR VEHICLE WITH AMT}[0001] SHIFT CONTROL METHOD FOR VEHICLE WITH AMT [0002]

본 발명은 AMT(AUTOMATED MANUAL TRANSMISSION)를 탑재한 차량이 내리막길을 크립 주행하는 경우의 변속 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift control method when a vehicle equipped with an AMT (Automated Manual Transmission) runs on a downhill road.

AMT는 자동화 수동 변속기로서, 종래 수동변속기 메커니즘을 자동적으로 조작할 수 있도록 구성된 변속기를 말하는 바, 엔진으로부터 변속기로 입력되는 동력을 단속하는 클러치의 작동과 변속기 내부에서 실질적으로 변속을 수행하는 셀렉팅 및 쉬프팅 작동을 액츄에이터로 자동적으로 수행하도록 한다.
The AMT is an automatic manual transmission, which is a transmission configured to automatically operate a conventional manual transmission mechanism. The AMT is an automatic manual transmission that includes a clutch that interrupts the power input from the engine to the transmission, a selection that substantially shifts within the transmission, The shifting operation is automatically performed by the actuator.

DCT(DOUBLE CLUTCH TRANSMISSION)는 엔진으로부터 변속기로 입력되는 동력을 단속하는 클러치가 2개 구비된 것으로서, 실질적으로는 AMT에 속하는 것으로 볼 수 있다.
DCT (DOUBLE CLUTCH TRANSMISSION) is provided with two clutches for interrupting the power input from the engine to the transmission, and can be regarded as substantially belonging to the AMT.

한편, DCT를 탑재한 차량은 클러치를 슬립시키는 제어를 통해 차량의 발진제어를 수행하며, 이때, 엔진의 아이들 동력을 이용하여 주행하는 상태를 크립(CREEP) 주행이라고 하는데, 일반적으로 목표 차속을 정하여 그 속도를 유지하도록 클러치를 적절히 슬립시키는 방법이 사용된다.
On the other hand, a vehicle equipped with a DCT carries out oscillation control of the vehicle through slip control of the clutch. At this time, a state in which the vehicle travels using the idle power of the engine is called creep (CREEP) A method of appropriately slipping the clutch to maintain the speed is used.

상기 DCT와 같은 AMT를 탑재한 차량이 내리막길에서 크립 주행 시, 클러치를 제어하는 방법은 2가지가 있을 수 있는데, 차량이 목표 차속에 도달하면 클러치를 해제하는 하나의 방법과, 클러치의 슬립을 줄여 록(LOCK) 상태를 형성하여 엔진 브레이크를 유도하는 방법이 있다.
There are two methods of controlling the clutch when a vehicle equipped with an AMT such as the DCT controls a clutch when traveling on a downhill road. One method of releasing the clutch when the vehicle reaches a target vehicle speed, There is a method of inducing the engine brake by forming a lock state.

운전자의 입장에서, 크립 주행 시, 약한 경사의 내리막길에서는 클러치를 해제하여 주행하는 것이 차속을 빨리 증가시킬 수 있고 가속감을 느끼게 할 수 있어서 좋지만, 경사가 급한 내리막길에서는 클러치를 해제하여 주행하게 되면 차속이 너무 빨리 증가하여 브레이크를 자주 밟게 되므로 불편하고 불안감을 유발할 수 있다.
From the viewpoint of the driver, it is good that the vehicle can be quickly accelerated and the acceleration sensation can be obtained by releasing the clutch when the vehicle is traveling on a downhill road with a weak inclination at the time of a creep. However, The vehicle speed increases too quickly, and the brakes are frequently stepped on, which can cause discomfort and anxiety.

상기의 발명의 배경이 되는 기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.It will be appreciated that those skilled in the art will appreciate that the described embodiments are provided merely for the purpose of promoting an understanding of the background of the present invention, It will not.

도 3은 도 1의 클로즈제어단계를 설명한 그래프이다.1 is a flowchart showing an example of applying an embodiment of a shift control method of an AMT vehicle to a DCT according to the present invention,
Figure 2 is a graph illustrating the open control step of Figure 1,
3 is a graph illustrating the close control step of FIG.

도 1 내지 도 3을 참조하면, 본 발명 AMT차량의 변속제어방법의 실시예는, 내리막길 크립 주행인지를 판단하는 주행모드판단단계(S100)와; 내리막길 크립 주행인 경우, 운전자가 내리막길에서 차량의 가속감을 원하는지 감속감을 원하는지에 대한 운전자의 의도를 차량의 조작수단을 통해 파악하는 의도파악단계(S110)와; 상기 의도파악단계(S110) 수행결과, 내리막길 크립 주행시 운전자가 가속감을 원하는 것으로 판단되는 경우, AMT의 클러치를 오픈하는 오픈제어단계(S120)와; 상기 의도파악단계(S110) 수행결과, 내리막길 크립 주행시 운전자가 감속감을 원하는 것으로 판단되는 경우, AMT의 클러치를 체결하여 록 상태로 하는 클로즈제어단계(S130)를 포함하여 구성된다.
1 to 3, an embodiment of a shift control method for an AMT vehicle according to the present invention includes: a traveling mode determination step (S100) for determining whether a downhill creep traveling; A step S110 of grasping the intention of the driver as to whether the driver desires acceleration or deceleration of the vehicle on the downhill road through the operation means of the vehicle when the vehicle is on the downhill creep; An open control step (S120) of opening the clutch of the AMT when it is determined that the driver desires acceleration feeling at the time of downhill creep traveling as a result of the intention grasping step (S110); And a closing control step (S130) of locking and closing the clutch of the AMT when it is determined that the driver desires a deceleration feeling at the time of downhill creeping as a result of performing the intent grasping step (S110).

즉, 차량이 내리막길을 주행하고 있는 상황에서 운전자가 가속페달을 밟지 않아 크립 주행 상황이 되는 경우, 운전자가 차량에 구비된 조작수단을 통해 선택하는 것에 따라, 상기 오픈제어단계(S120)를 수행하여 가속감을 원하는 운전자의 요구를 충족시키거나, 상기 클로즈제어단계(S130)를 수행하도록 하여 감속감과 안정감을 원하는 운전자의 요구를 충족시키도록 함으로써, 운전자의 요구에 최대한 부응하는 차량의 운전상태를 구현할 수 있도록 하는 것이다.
That is, when the driver is in the creep running state because the driver does not step on the accelerator pedal while the vehicle is traveling on the downhill road, the driver performs the open control step (S120) by selecting through the operating means provided in the vehicle The driver's request for the acceleration feeling is satisfied, or the closing control step (S130) is performed to satisfy the demand of the driver who desires the feeling of deceleration and the feeling of stability, thereby realizing the driving state of the vehicle that best suits the driver's request .

상기 주행모드판단단계(S100)에서는 내리막길 주행인지의 여부를 차량에 탑재된 경사센서 등의 신호를 받아 판단하고, 운전자가 가속페달을 밟은 정도를 가속페달센서 등의 신호로부터 판단하는 바, 차량이 내리막 경사로를 주행하는 상황인데 운전자가 가속페달을 밟고 있지 않은 것으로 판단되면, 현 상태를 내리막길 크립 주행인 것으로 판단한다.
In the driving mode determination step S100, whether or not the vehicle is traveling on a downhill road is determined by receiving a signal from a tilt sensor or the like mounted on the vehicle, and the degree by which the driver depresses the accelerator pedal is determined from a signal of the accelerator pedal sensor, If it is determined that the driver is not stepping on the accelerator pedal, it is determined that the current state is the downhill creep running.

상기 의도파악단계(S110)에서는 운전자의 의도를 상기 차량의 조작수단에 의해 파악하는 바, 상기 조작수단은 변속레버 또는 별도로 구비된 모드선택스위치 등이 될 수 있을 것이다.
In the intention grasping step (S110), the intention of the driver is grasped by the operating means of the vehicle, and the operating means may be a shift lever or a mode selection switch separately provided.

예컨대, 상기 조작수단이 변속레버인 경우에는, 상기 변속레버의 변속레인지 선택 상태에 의해 상기 운전자의 의도를 파악하는 바, 변속레버가 D레인지에 있는 경우, 운전자가 가속감을 원하는 것으로 판단하고, 변속레버가 매뉴얼레인지로 조작되는 경우, 운전자가 감속감을 원하는 것으로 판단하는 실시예가 가능할 것이며, 도 1은 이와 같은 실시예를 DCT 차량에 적용하는 예이다.
For example, when the operating means is a shift lever, the intention of the driver is grasped by the shift range selection state of the shift lever. When the shift lever is in the D range, the driver determines that the driver desires acceleration feeling. In the case where the lever is operated in the manual range, it is possible that the driver decides that he or she desires a deceleration feeling, and Fig. 1 is an example of applying such an embodiment to a DCT vehicle.

또는, 상기 조작수단이 모드선택스위치인 경우, 상기 의도파악단계(S110)에서는 별도로 차량에 구비된 상기 모드선택스위치의 조작 상태에 따라, 운전자가 가속감을 원하는지 감속감을 원하는지를 판단하도록 할 수 있을 것이다.
Alternatively, when the operating means is a mode selection switch, the intention grasping step (S110) may be configured to determine whether the driver desires acceleration feeling or deceleration feeling depending on the operation state of the mode selection switch provided in the vehicle .

한편, 상기 오픈제어단계(S120) 수행 중, 운전자가 가속페달을 밟으면, 현재의 차속에 따른 목표 변속단으로 변속하면서 해당 클러치를 체결하는 오픈제어종료단계(S140)를 수행한다.
Meanwhile, when the driver depresses the accelerator pedal during the open control step S120, an open control end step (S140) is performed in which the clutch is engaged while shifting to the target speed change stage corresponding to the current vehicle speed.

즉, 운전자가 상기 오픈제어단계(S120) 수행 중, 가속페달을 밟으면, 적극적으로 차량을 가속시키려는 의지가 있는 것이므로, 상기 오픈제어종료단계(S140)를 수행하여, 본 발명의 제어를 종료하고, 통상의 경우와 같이 엔진으로부터의 구동력으로 차량이 구동되도록 제어하는 것이다.
That is, when the driver depresses the accelerator pedal during the open control step S120, there is a willingness to actively accelerate the vehicle. Therefore, the open control ending step S140 is performed to end the control of the present invention, So that the vehicle is driven by the driving force from the engine as in the normal case.

여기서, 상기 해당 클러치란, 목표 변속단이 배치되어 있는 변속기 입력축에 연결된 클러치를 말하는 바, 클러치가 하나인 AMT에서는 당연히 하나의 클러치가 해당 클러치가 되겠지만, DCT의 경우에는 두 클러치 중 해당 변속단이 배치된 입력축으로 연결된 클러치가 되는 것이다.
Here, the clutch means a clutch connected to a transmission input shaft in which a target speed change stage is disposed. In the case of an AMT having one clutch, one clutch will of course be a corresponding clutch. However, in case of DCT, And the clutch is connected to the disposed input shaft.

상기 오픈제어종료단계(S140) 수행 시, DCT 탑재 차량의 경우에는, 운전자가 가속페달을 밟으면, 현재의 차속에 따른 목표 변속단으로 변속하면서 상기 목표 변속단이 배치된 입력축에 연결된 클러치를 체결하고 다른 나머지 한 클러치는 오픈 상태를 유지하는 싱글클러치변속을 수행한다.
In the case of the DCT-equipped vehicle, when the driver depresses the accelerator pedal during the open control termination step (S140), the clutch connected to the input shaft on which the target speed change stage is disposed is engaged while shifting to the target speed change stage corresponding to the current vehicle speed And the remaining one clutch performs the single clutch shifting maintaining the open state.

도 2의 A부분이 본 발명의 오픈제어단계(S120)를 나타내고, B부분은 상기 오픈제어종료단계(S140)를 수행하는 것으로서, DCT에 적용되는 상황이므로 상기 싱글클러치변속이 이루어지고 있는 것을 나타내며, C부분 이후에는 통상적인 DCT차량의 일반적인 주행상황으로 더블클러치변속이 이루어지는 상황을 설명하고 있다.
A portion of FIG. 2 represents an open control step (S120) of the present invention, and a portion B of FIG. 2 performs the open control ending step (S140), which is a situation applied to the DCT, , And after the portion C, a double clutch shift is performed due to a general driving situation of a typical DCT vehicle.

즉, A부분에서 상기 오픈제어단계(S120)를 수행함에 따라, DCT의 두 클러치인 클러치 1과 클러치 2는 모두 엔진으로부터 동력이 차단되는 상태로 해제되어 엔진속도와 무관하게 차속의 증가에 따라 속도가 증가하고 있으며, B부분에서 운전자가 가속페달을 밟기 시작함에 따라 상기 오픈제어종료단계(S140)가 수행되며 이때 싱글클러치변속이 이루어지는 것을 설명하고 있는 것이다.
That is, by performing the open control step (S120) at the A portion, both of the clutches 1 and 2 of the DCT are released from the engine to a state in which the power is interrupted, so that the speed And the open control end step (S140) is performed as the driver starts to depress the accelerator pedal in the portion B, and the single clutch shift is performed at this time.

상기 클로즈제어단계(S130)에서는, 현재의 차속에 따른 목표 변속단에 따라 변속을 수행하면서 클러치는 변속을 위해 해제했다가 다시 결합시켜 유지하도록 제어한다.
In the closing control step (S130), the clutch is controlled so as to release the gear for shifting while maintaining the engaged state, while performing the shift according to the target speed change stage according to the current vehicle speed.

상기 클로즈제어단계(S130) 수행 시, DCT 탑재 차량의 경우에는, 목표 변속단에 따라 변속을 수행할 때 이전 변속단에 연결되는 클러치는 해제하면서 새로운 목표 변속단에 연결되는 클러치는 체결하는 더블클러치변속을 수행한다.
In the DCT-equipped vehicle, the clutch connected to the new speed change stage is released while the clutch connected to the previous speed change stage is engaged when performing the shift according to the target speed change stage in the closing control step (S130) And performs a shift.

도 3은 DCT 탑재 차량에서 상기 클로즈제어단계(S130)를 수행하는 것을 예시한 것으로서, D부분에서 클러치 1이 엔진에 연결되어 클러치 1의 속도가 엔진의 속도와 같은 상태를 유지하다가, 차속이 증가함에 따라 클러치 2에 연결된 상위 변속단으로 변속이 이루어지며, 이때 클러치 1은 해제하면서 클러치 2를 결합하는 더블클러치변속이 이루어져서, 변속 후 어느 한 클러치는 엔진에 연결된 상태를 지속적으로 유지하게 되어 엔진 브레이크의 효과가 지속되게 하는 것이다.
