The main and secondary throttle valves 2 and 3, the fuel injection amount detector 4 and the ignition timing of which the opening amount is changed in response to the displacement angle of the accelerator delivery 1 An engine unit 100 having a detector 5; An automatic transmission (200) integrally installed in the engine unit (100), the driving of which is controlled by a hydraulic control unit (500); Engine rotation speed detection unit 6, intake air amount detection unit 7, intake air temperature detection unit 8, throttle valve opening amount detection unit 9, vehicle speed detection unit 10, engine water temperature detection unit 11, brake switch 12 And an engine for selectively driving the engine unit 100 and the automatic transmission 200 by receiving the output signals of the pattern select switch 13, the overdrive switch 14, and the quick down switch 15.

본 발명 방법은 제2도에 나타낸 바와 같이, 각부에서 소정의 신호들이 입력되면 변속패턴이 m⇒1의 퀵 다운(Kick down)상태인지를 판단하는 제1과정과; 차속(V)이 소정값()보다 큰지의 여부를 판단하는 제2과정과; 트로틀밸브의 개도량 변화율(△θ)이 소정값()) 보다 큰지를 판단하는 제3과정과; 변속전의 트로틀밸브 개도량(θb)이 소정값(예:100) 보다 작은지를 판단하는 제4과정과; 퀵 다운 스위치(15)가 온상태인지를 판단하는 제5과정과; 상기의 과정에서 모두 만족하면 엔진출력을 억제하는 제6과정과; 상기의 과정에서 모두 만족되지 않으면 통상의 엔진출력이 발생되도록 하는 제7과정으로 이루어진 것을 특징으로 한다.As shown in FIG. 2, the method includes: a first step of determining whether a shift pattern is a quick down state of m ⇒ 1 when predetermined signals are input from each unit; The vehicle speed V is a predetermined value ( A second process of determining whether greater than; The opening degree change rate (Δθ) of the throttle valve is a predetermined value ( 3) judging whether it is greater; A fourth step of determining whether the throttle valve opening amount θb before the shift is smaller than a predetermined value (eg, 10 0 ); A fifth step of determining whether the quick down switch 15 is on; A sixth step of suppressing engine output when all of the above steps are satisfied; If all of the above processes are not satisfied, it is characterized in that the seventh process for generating a normal engine output.
이와같은 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as follows.
먼저, 엔진 콘트롤 유니트(300)와 자동변속기 콘트롤 유니트(400) 및 유압제어장치(500)를 구비하고 엔진부(100)와 자동변속기(200)가 일체로 형성된 자동차에서는 초기 상기 엔진 및 자동변속기 콘트롤 유니트(300,400)에 연결된 각부를 통해 소정의 출력신호들을 입력받은 다음, 변속패턴이 m⇒1의 퀵 다운상태(즉, m과 1의 차이가 소정가뵤 이상, 예를들어 변속폭이 2이상)인지를 판단하게 된다.First, in an automobile having an engine control unit 300, an automatic transmission control unit 400, and a hydraulic control device 500, and the engine unit 100 and the automatic transmission 200 are integrally formed, the engine and the automatic transmission control are initially performed. After the predetermined output signals are inputted through the respective parts connected to the units 300 and 400, the shift pattern is in a quick down state of m⇒1 (that is, the difference between m and 1 is a predetermined value or more, for example, the shift width is 2 or more). It will be judged.
이어서, 차속센서(10)에서 검출된 차속(V)이 소정값())보다 큰지의 여부를 판단하여 저속일 경우는 구동력 발생을 우선적으로 처리한다.Subsequently, the vehicle speed V detected by the vehicle speed sensor 10 is a predetermined value ( In case of low speed, the driving force is given priority.
이후, 주,부 트로틀밸브(2,3)의 개도량 변화율(△θ)이 소정값()) 보다 큰지를 판단하게 되는데, 이는 급격한 엔진출력 변화유무를 체크하기 위한 것이다.Thereafter, the opening degree change rate (Δθ) of the main and secondary throttle valves 2 and 3 is a predetermined value ( It is determined whether or not it is larger, which is to check whether there is a sudden change in engine power.
이와같이 트로틀밸브의 개도량 변화율이 체크되면 변속전의 트로틀밸브 개도량(θb)이 소정값(예:100)보다 작은지를 판단하게 되는데, 이 경우 상기 트로트밸브(2,3)의 개도량(θb)은 변속 판정전의 소정시간전 트로틀밸브의 개도량이어도 좋다.When the rate of change of the opening amount of the throttle valve is checked as described above, it is determined whether the opening amount θb of the throttle valve before the shift is smaller than a predetermined value (eg, 10 0 ), in which case the opening amount θb of the trot valves 2 and 3 is determined. May be an opening amount of the throttle valve before a predetermined time before the shift determination.
이어 액셀패달(1)의 변화폭이 큰지의 여부를 판별하기 위해 퀵 다운 스위치(15)가 온상태인지를 판단하여 만약 퀵 다운 스위치(15)마져 온상태에 있으면, 엔진출력을 억제시켜 급격하게 엔진의 출력이 변화되는 것을 방지하게 된다.Then, to determine whether the quick change of the accelerator pedal 1 is large or not, it is determined whether the quick down switch 15 is in an on state. This prevents the output of.
그러나, 상기에서 모든 조건이 만족되지 않으면 통상시와 마찬가지로 엔진의 출력이 발생되도록 한다.However, if all of the above conditions are not satisfied, the engine output is generated as usual.
한편, 제3도는 시간의 진행에 따른 엔진회전수(NC)의 변화를 나타낸 그래프로써, 본 발명 방법을 적용하면 m⇒1 다운 쉬프트때의 엔진회전수 변화특성은 종래와 비교할시 완만하게 변화됨을 알 수 있다.On the other hand, Figure 3 is a graph showing the change in the engine speed (NC) with the progress of time, when applying the method of the present invention, the engine speed change characteristics when m ⇒ 1 downshift is changed slowly compared with the conventional Able to know.
이상에서 설명한 바와 같이 본 발명에 의하면, 액셀폐달을 밟아 다운 쉬프트가 나타나는 경우, 또는 트로틀밸브의 개도량 변화와 트로틀밸브의 개도 변화율 중 어느 한쪽이 소정값을 넘어설 경우 엔진출력의 변화를 트로틀밸브 개도의 변화와 비교하여 액셀답력에 따른 급격한 토크변화를 방지하므로 자동차의 주행성을 대폭 향상시킬 수있는 것이다.As described above, according to the present invention, when the downshift occurs when the accelerator pedal is pressed or when either the change in the opening amount of the throttle valve or the change rate of the opening degree of the throttle valve exceeds a predetermined value, the change in engine output is changed to the throttle valve. Compared with the change in the opening degree, it prevents the sudden torque change due to the accelerator response power, which can greatly improve the driving performance of the car.
