이 발명은 자동 변속기의 듀티율 판정 장치 및 그 방법에 관한 것으로서, 더욱 상세하게 말하자면, 자동차의 주행 상태에 따른 최적의 듀티율을 판정하여 판정된 듀티율에 따라 자동 변속기의 제어 동작을 실행하는 자동차의 주행 상태에 따른 듀티율 판정 장치 및 그 방법에 관한 것이다.The present invention relates to an apparatus for determining the duty rate of an automatic transmission and a method thereof, and more particularly, to a driving state of a vehicle that determines an optimal duty rate according to a driving state of a vehicle and executes a control operation of the automatic transmission according to the determined duty ratio. It relates to a duty rate determination device according to the present invention and a method thereof.
일반적으로 자동 변속기가 장착되어 있는 자동차는, 자동차의 주행속도에 따라 설정되어 있는 변속 범위 안에서 유압을 제어하여 자동으로 목표 변속단의 변속 기어가 동작될 수 있도록 한다.In general, a vehicle equipped with an automatic transmission controls the hydraulic pressure within a shift range set according to the driving speed of the vehicle so that the shift gear of the target shift stage may be automatically operated.
그러므로 엔진(engine)의 출력 동력에 따라 토크 컨버터(torque converter)를 동작시켜 유체의 회전력을 제어하고, 자동차의 동작 상태에 따른 해당 변속 기어가 동작될 수 있도록 변속 제어 장치에서 인가되는 제어 신호에 따라 해당 밸브로 유압이 작용하여 변속동작이 이루어질 수 있도록 한다.Therefore, the torque converter is operated according to the output power of the engine to control the rotational force of the fluid, and according to the control signal applied from the shift control device so that the shift gear according to the operating state of the vehicle can be operated. Hydraulic pressure acts on the valve to allow shifting.
따라서 유압에 따라 동작 상태가 제어되는 자동 변속기가 장착된 자동차는, 해당하는 변속 기어의 동작 상태를 가변시키기 위해 엔진과의 동력을 차단시키는 클러치 페달(clutch pedal)의 동작이 필요하지 않으므로 운전자의 운전 피로를 경감시킬 수 있고, 주행중 운전자의 오동작이나 운전미숙 등으로 인한 엔진 스톨(engine stall)이 발생하지 않으므로 초보자의 경우에도 운전 동작을 용이하게 할 수 있다.Therefore, a vehicle equipped with an automatic transmission in which the operating state is controlled according to the hydraulic pressure does not require the operation of a clutch pedal to cut off power from the engine in order to change the operating state of the corresponding shift gear. Fatigue can be reduced, and an engine stall does not occur due to a malfunction of the driver or immaturity of the driver while driving, so that even a beginner can easily operate the driving.
그러므로 자동 변속기는 운전자의 변속 레버의 선택 위치에 따라 포트변환이 이루어져 오일 펌프로부터 유체압을 공급받고, 상기 유체압에 의해 유압 밸브의 동작 상태가 가변되어 변속기어 메카니즘의 기어단 중 어느 하나의 변속단을 선택하기 위한 유압 작동 마찰 요소의 동작 상태를 제어한다.Therefore, the automatic transmission receives a fluid pressure from the oil pump by changing the port according to the selected position of the driver's shift lever, and the operating state of the hydraulic valve is changed by the fluid pressure so that any one gear stage of the transmission gear mechanism is shifted. Controls the operating state of the hydraulically actuated friction element for selecting stages.
클러치나 브레이크로 이루어져 있는 마찰 요소의 선택적인 동작에 따라 유성 기어 장치의 작동이 전환되어, 적절한 변속비가 행해진 후 드라이브 기어로 전달된다.The action of the planetary gear arrangement is switched in accordance with the selective operation of the friction element consisting of a clutch or brake, which is then transmitted to the drive gear after an appropriate transmission ratio is made.
상기 드라이브 기어로 변속된 동력이 전달되면, 변속된 동력은 상기 드라이브 기어와 치차 결합된 드리븐 기어에 의해 종감속 기어와 치차 결합된 종동 기어로 전달되어, 바퀴의 회전 동작을 제어한다.When the shifted power is transmitted to the drive gear, the shifted power is transmitted to the driven gear geared to the longitudinal reduction gear by the driven gear geared to the drive gear, thereby controlling the rotational movement of the wheel.
상기와 같은 자동차의 주행 상태에 따른 목표 변속단을 결정하기 위해, 가속 페달의 조작 정도에 따라 변화하는 스로틀 밸브의 개도량과 자동차의 주행 속도에 따라 이미 변속 패턴이 설정되어 있다.In order to determine the target speed change stage according to the driving state of the vehicle as described above, the shift pattern is already set according to the opening amount of the throttle valve which changes according to the operation degree of the accelerator pedal and the driving speed of the vehicle.
그러므로, 상기 설정된 변속 패턴에 따라 목표 변속단이 결정되고, 결정된 목표 변속단으로의 변속 동작을 실행할 수 있도록 한다.Therefore, the target shift stage is determined according to the set shift pattern, and the shift operation to the determined target shift stage can be executed.
상기와 같이 자동차의 주행 상태에 따른 목표 변속단으로의 변속 동작을 실행할 경우, 각 해당 마찰 요소로 작용하는 유압의 크기를 제어하기 위해 압력 제어 솔레노이드 밸브의 제어 신호의 듀티율을 제어한다.As described above, when the shift operation to the target shift stage according to the driving state of the vehicle is performed, the duty ratio of the control signal of the pressure control solenoid valve is controlled to control the magnitude of the hydraulic pressure acting as the corresponding friction element.
그러므로 제1도에 도시된 것처럼 각 해당 목표 변속단으로의 변속 동작을 실행하기 위한 변속 제어 신호가 출력된 후부터 변속 제어 동작에 따라 각 설정된 듀티값과 기울기가 설정되어, 각 변속 상태에 따라 이미 설정되어 있는 상태로 압력 제어 솔레노이드 밸브의 동작이 제어될 수 있도록 한다.Therefore, as shown in FIG. 1, after the shift control signal for executing the shift operation to the respective target shift stage is output, the set duty value and the slope are set according to the shift control operation, and are already set according to the shift state. This allows the operation of the pressure control solenoid valve to be controlled.
따라서 해당 목표 변속단으로의 신속하고 정확한 변속 동작이 이루어지고, 동작 상태가 변화하는 마찰 요소의 상태가 변화할 경우 발생하는 쇼크를 감소시켜 변속감을 향상시킬 수 있도록 한다.Therefore, a quick and accurate shifting operation is performed to the target shift stage, and the shock generated when the state of the friction element in which the operating state changes is changed, thereby improving the shifting feeling.
그러나 상기와 같이 해당 변속단으로 변속 동작이 이루어질 경우, 변속 상태에 따라 각 설정되어 있는 듀티율에 따라 자동 변속기의 제어압을 제어할 경우, 상기 설정된 듀티율은 당지 판정된 목표 변속단에 따른 변속 진행 과정이나 변속 시간에 따라 설정되어 있다.However, when the shift operation is performed to the shift stage as described above, when the control pressure of the automatic transmission is controlled according to the duty ratio set for each shift state, the set duty ratio is the shift progress process according to the target shift stage determined locally. Or according to the shift time.
그러므로 실제 자동 변속기의 동작에 영향을 미치는 각 변수를 고려하지 않으므로, 자동차의 주행 기간이나 사용되는 자동 변속기의 종류 또는 유압을 생시키기 위해 사용되는 변속 오일 등 자동 변속기의 제어 동작에 영향을 미치는 각 요소의 상태를 전혀 고려하지 않고 설정된 듀티율에 따라 자동 변속기의 동작이 제어된다.Therefore, since each variable affecting the operation of the automatic transmission is not taken into consideration, the factors affecting the control operation of the automatic transmission, such as the driving period of the vehicle, the type of automatic transmission used, or the transmission oil used to generate hydraulic pressure, are considered. The operation of the automatic transmission is controlled according to the set duty ratio without considering the state of.
따라서, 실제 자동차의 주행 상태나 주행 조건에 따라 적절한 유압 제어 동작이 이루어지지 않으므로, 적절한 변속 제어가 이루어지지 않고 변속 쇼크가 발생하고 자동차의 내구성을 약화시키는 문제가 발생한다.Therefore, since the proper hydraulic control operation is not performed according to the actual driving condition or the driving condition of the vehicle, there is a problem in that shift shock occurs without proper shift control and the durability of the vehicle is weakened.
그러므로 이 발명의 목적은 상기한 종래의 문제점을 해결하기 위한 것으로서, 자동차의 실제 상태에 따라 최적의 듀티율을 설정하여 자동 변속기의 변속 제어를 실행하므로 자동차의 상태에 따른 정확한 변속 동작이 이루어져 변속감을 향상시킬 수 있도록 하는 자동차의 주행 상태에 따른 듀티율 판정 장치 및 그 방법을 제공하기 위한 것이다.Therefore, an object of the present invention is to solve the above-mentioned problems, and by setting the optimum duty ratio according to the actual state of the vehicle to perform the shift control of the automatic transmission, the shifting operation is performed accurately according to the state of the vehicle, thereby improving the shifting feeling. It is to provide an apparatus and method for determining the duty rate according to the driving state of the vehicle to be able to make.
상기한 목적을 달성하기 위한 수단으로써 이 발명의 구성은, 자동차의 주행 상태나 자동차의 상태에 따라 출력되는 다수개의 전기 신호의 상태가 변화하여, 자동차의 주행 상태나 자동차 상태를 판정할 수 있도록 하는 자동차 상태 감지 수단과; 상기 자동차 상태 감지 수단에서 출력되는 신호를 이용하여 자동차의 상태나 주행 상태를 판정하여 판정하고자 하는 변수의 값을 판정하고, 이미 설정되어 있는 데이타를 이용하여 각 판정된 변수의 값에 해당하는 각 듀티율을 판정하고, 각 판정된 듀티율을 시간에 대한 함수로 산출하여 최적의 듀티율을 설정하여, 설정된 듀티율에 해당하는 변속 제어를 위한 제어 신호를 압력 제어 솔레노이드 밸브로 출력하여 변속 제어를 위한 압력의 크기를 변화시키는 변속 제어 수단을 포함하여 이루어져 있다.As a means for achieving the above object, the configuration of the present invention is such that the state of a plurality of electric signals outputted according to the driving state of the vehicle or the state of the vehicle changes so that the driving state or the vehicle state of the vehicle can be determined.

It includes a shift control means for changing.
상기한 목적을 달성하기 위한 이 발명의 또다른 구성은, 자동차 상태 감지 수단에서 출력되는 신호를 이용하여 자동차의 상태나 주행 상태를 판정하여 판정하고자 하는 변수의 값을 판정하여, 이미 설정되어 있는 데이타를 이용하여 각 판정된 변수의 값에 해당하는 각 듀티율을 판정하는 단계와; 각 판정된 듀티율을 시간에 대한 함수로 산출하는 단계와; 설정된 각 듀티율에 대한 시간의 함수을 이용하여 최적의 듀티율을 설정하여, 설정된 듀티율에 따라 변속 제어를 위한 제어 신호를 출력하는 단계를 포함하여 이루어져 있다.Another configuration of the present invention for achieving the above object is to determine the value of a variable to be determined by determining the state of the vehicle or the driving state by using a signal output from the vehicle state detecting means, and the data already set.

이하, 첨부된 도면을 참조로 하여 이 발명의 가장 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention.
제1도를 참고로 하여 이 발명의 실시예에 따른 구성을 살펴보면, 자동차의 주행 상태나 자동차의 상태에 따라 출력되는 다수개의 전기 신호의 상태가 변화하여, 자동차의 주행 상태나 자동차 상태를 판정할 수 있도록 하는 자동차 상태 감지부(1)와, 상기 자동차 상태 감지부(1)에서 출력되는 신호를 이용하여 자동차의 상태나 주행 상태를 판정하여 판정하고자 하는 변수의 값을 판정하고, 이미 설정되어 있는 데이타를 이용하여 각 판정된 변수의 값에 해당하는 각 듀티율을 판정하고, 각 판정된니 듀티율을 시간에 대한 함수로 산출하여 최적의 듀티율을 설정하여, 설정된 듀티율에 해당하는 변속 제어를 위한 제어 신호를 출력하는 변속 제어부(2)와, 상기 변속 제어부(2)에서 출력되는 제어 신호의 듀티율에 따라 동작상태가 변화하여 해당 크기의 유압을 발생시켜 적절한 변속 동작이 이루어질 수 있도록 하는 압력 제어 솔레노이드 밸브(3)로 이루어져 있다.Referring to FIG. 1, a configuration according to an exemplary embodiment of the present invention may be used. The state of a plurality of electric signals output according to the driving state of a vehicle or the state of the vehicle may change, and thus the driving state or the vehicle state of the vehicle may be determined. The vehicle state detection unit 1 and the signal output from the vehicle state detection unit 1 are used to determine the state of the vehicle or the driving state to determine the value of the variable to be determined, which is already set. Determines the duty rate corresponding to the value of each determined variable by using the data, calculates each determined knee duty rate as a function of time, sets an optimum duty rate, and controls a control signal for shift control corresponding to the set duty rate. The operation state is changed according to the duty cycle of the shift control unit 2 and the control signal output from the shift control unit 2 to output the hydraulic pressure of the corresponding size. Caused by the pressure-control it consists of a solenoid valve 3 to be made to an appropriate speed change operation.
상기와 같이 이루어져 있는 이 발명의 동작은 다음과 같다.The operation of the present invention made as described above is as follows.
먼저, 각 장치의 동작에 필요한 전원이 공급되면, 각 해당하는 동작을 실행한다.First, when power required for the operation of each device is supplied, each corresponding operation is executed.
따라서 변속 제어부(2)는 자동차 상태 감지부(1)에서 출력되는 다수개의 감지 신호를 판독하여(S11), 자동차나 자동차의 주행 상태에 따라 변화하는 각 장치나 물체의 상태를 판정하고, 자동차의 주행 상태나 물체의 상태에 따라 제4a도∼제4c도에 도시된 것처럼 각 해당 상태에 따라 이미 설정되어 있는 데이타를 이용하여 각 상태에 해당하는 듀티율을 판정한다(S12).Therefore, the shift control unit 2 reads a plurality of detection signals output from the vehicle state detection unit 1 (S11) to determine the state of each device or object that changes according to the driving state of the vehicle or the vehicle, According to the running state or the state of the object, as shown in FIGS. 4A to 4C, the duty rate corresponding to each state is determined using the data already set according to each corresponding state (S12).
이 발명의 실시예에서 사용되는 상태 판정은, 변속 오일의 온도와 스로틀 밸브의 개도 정도에 따라 이미 설정되어 있는 엔진의 각 출력 토크, 및 사용되는 자동 변속기의 종류나 자동차의 주행 거리에 따라 변화하는 자동 변속기의 편차 등이 있다.The state determination used in the embodiment of the present invention varies depending on the output torque of the engine already set according to the temperature of the transmission oil and the opening degree of the throttle valve, and the type of automatic transmission used or the driving distance of the vehicle. Deviation of automatic transmission.
따라서 각 해당하는 변속 오일의 온도와 엔진 토크 및 자동 변속기의 편차를 판정한 후, 판정된 각 온도나 토크 및 편차에 해당하는 듀티율을 이미 설정된 데이타 맵을 이용하여 판정할 수 있다.Therefore, after determining the temperature of each corresponding transmission oil and the deviation of the engine torque and the automatic transmission, the duty rate corresponding to the determined temperature, torque and deviation can be determined using the data map already set.
상기와 같이 이미 설정된 변수에 해당하는 각 듀티율이 산출되면, 변속 제어부(2)는 산출된 듀티율을 시간에 대한 함수로 변환하여 제5도에 도시된 것처럼 시간에 대한 하나의 함수로 설정한다(S13).When each duty ratio corresponding to the variable already set as described above is calculated, the shift control unit 2 converts the calculated duty ratio into a function of time and sets it as a function of time as shown in FIG. 5 (S13). ).
그러므로 자동차나 자동차의 주행 상태에 따른 각 변수에 대한 하나의 함수가 설정되면, 변속 제어부(2)는 각 함수에 해당하는 다수개의 듀티율을 이용하여 제5도의 빗금친 부분에 해당하는 최적 조건의 듀티율을 설정한다(S14).Therefore, when one function is set for each variable according to the vehicle or the driving condition of the vehicle, the shift control unit 2 uses the duty ratio corresponding to each function and the duty ratio of the optimum condition corresponding to the hatched portion of FIG. Set (S14).
상기와 같은 동작을 통해 자동차의 상태나 주행 상태에 해당하는 최적의 듀티율이 설정되면, 변속 제어부(2)는 설정된 듀티율을 이용하여 압력 제어 솔레노이드 밸브(3)의 동작을 제어하여, 적절한 변속 동작이 이루어질 수 있도록 한다.When the optimum duty ratio corresponding to the state of the vehicle or the driving state is set through the above operation, the shift control unit 2 controls the operation of the pressure control solenoid valve 3 using the set duty rate, so that an appropriate shift operation is performed. Make it happen.
그러므로 상기와 같이 자동 변속기의 변속 동작에 영향을 미치는 각 변수의 값에 따라 각 해당 듀티율을 설정한 후, 각 설정된 해당 듀티율을 이용하여 최종 최적의 듀티율을 설정하여 자동 변속기의 변속 동작을 제어하므로, 자동차나 주행 상태에 따른 적절한 변속동작을 실행할 수 있다.Therefore, after setting the respective duty ratio according to the value of each variable affecting the shifting operation of the automatic transmission as described above, the final optimum duty rate is set using the set corresponding duty rate to control the shifting operation of the automatic transmission. Appropriate shifting operations can be performed according to the vehicle or driving conditions.
따라서 자동차의 주행 상태에 따른 적절한 변속 동작이 이루어지므로, 자동 변속기의 변속감을 향상시킬 수 있는 효과가 발생한다.Therefore, since the proper shift operation is made according to the driving state of the vehicle, there is an effect that can improve the shifting feeling of the automatic transmission.
