Description

자동변속기 차량의 급발진 방지 방법{METHOD FOR PREVENTING UNEXPECT START OF AUTO TRANSMISSION VEHICLE}METHOD FOR PREVENTING UNEXPECT START OF AUTO TRANSMISSION VEHICLE}

본 발명은 자동변속기 차량의 급발진 방지 방법에 관한 것으로, 특히 자동변속 차량에서 엔진 시동후 예기치 않은 변속기의 급발진 동작을 사전에 방지할 수 있도록 한 자동변속기 차량의 급발진 방지 방법에 관한 것이다.The present invention relates to a method for preventing sudden start of an automatic transmission vehicle, and more particularly, to a method for preventing sudden start of an automatic transmission vehicle that can prevent an unexpected start and stop operation of a transmission after starting an engine in an automatic transmission vehicle.

최근들어 자동변속기 차량에서 엔진 시동후 운전자의 의도에 관계없이 자동변속기가 오동작을 일으키면서 차량을 순간적으로 급전진 또는 급후진하면서 차량 운전자는 물론 그 주변 차량, 건물 및 그 부속물에 큰 손상을 입히게 되는 급발진 현상이 자주 발생되어 자동차업계 뿐만 아니라 소비자측에서 큰 문제점으로 대두되고 있는 실정이다.Recently, the automatic transmission malfunctions after the engine is started in the automatic transmission vehicle, causing the vehicle to momentarily move forward or backward, causing serious damage to the vehicle driver, the surrounding vehicle, the building, and its accessories. Sudden oscillation occurs frequently, which is a big problem not only in the automobile industry but also in the consumer side.

그러나 상기 급발진은 차량의 엔진 시동후 순간적으로 엔진 회전수가 급상승하면서 급전진 또는 급후진하는 현상으로, 이와 같은 현상은 현재로서 어떠한 요인에 의하여 야기되는 것인지 분명하게 밝혀지지 않고 있다.However, the rapid start is a phenomenon in which the engine speed suddenly increases or decreases rapidly after the engine is started, and it is not clear what causes such a phenomenon at present.

그러므로 종래에는 급발진 현상을 방지하기 위하여 엔진 시동후 급발진 조건 즉 아이들 스위치 온, 시동모드 이외 조건을 판단하여 급발진을 방지하도록 하였으나, 상기 스로틀 밸브가 전폐되지 않은 상태에서는 흡입 공기량에 의한 엔진 실린더에 공기량이 계속해서 유입되게 되므로 브레이크를 밟아도 제동을 시키지 못하게 되어 급발진을 방지할 수 없게 되는 문제점을 가지게 되었다.Therefore, in order to prevent the sudden start phenomenon, after starting the engine to determine the sudden start condition, i.e., the idle switch on, the start mode other than to determine the sudden start, but in the state that the throttle valve is not closed, the amount of air in the engine cylinder by the intake air volume Since it continues to flow, it does not allow braking even when the brake is applied, which causes a problem of preventing sudden starting.

따라서 본 발명의 목적은 자동변속 차량을 엔진 시동후 브레이크 스위치 온, 변속 전진 또는 후진, 스로틀 위치 센서값이 임의로 설정된 값 이하인 급발진 제어 조건에 만족하는가를 판단하고 엔진 회전수를 감지하여, 이 감지된 엔진 회전수가 급발진 판정 회전수에 도달 여부에 따라 점화시기 지연 및 아이들 속도 제어로 유량감소, 또는 엔진 회전수 편차에 따라 연료 차단을 수행하도록 함으로써, 급발진 발생 원인을 사전에 방지하고자 하는데 있다.Therefore, an object of the present invention is to determine whether the brake switch on, shift forward or reverse, the throttle position sensor value satisfies the rapid start control condition which is equal to or less than a randomly set value after the engine is started, and detects the engine speed by detecting the engine speed. It is intended to prevent the occurrence of the sudden start by precipitating the engine speed by the ignition timing delay and the idle speed control depending on whether the engine speed reaches the speed of the sudden start speed, or by stopping the fuel according to the engine speed deviation.

도 1은 본 발명에 이용되는 급발진 방지 장치의 개략적인 제어 블럭도.1 is a schematic control block diagram of a sudden start prevention device used in the present invention.

도 2는 본 발명 급발진 방지 방법에 대한 플로우챠트.Figure 2 is a flow chart for the sudden start prevention method of the present invention.

상기의 목적을 실현하기 위하여 본 발명은 엔진 시동후 급발진 제어조건이 성립하는가를 판단하는 단계와; 상기 단계에서 급발진 제어조건이 성립하면, 엔진 회전수를 감지하고, 이 감지된 엔진 회전수가 급발진 판정 회전수 이상인가를 판단하는 단계와; 상기 단계에서 감지된 실제 엔진 회전수가 급발진 판정 회전수 이상이면 상기 감지된 실제 엔진 회전수와 수온에 따라 임의로 설정된 목표 회전수와의 엔진 회전수 편차를 산출하고, 이 산출된 엔진 회전수 편차가 고위험 급발진 판정치에 해당하는 회전수 이상인가를 판단하는 단계와; 상기 단계에서 엔진 회전수 편차가 고위험 급발진 판정치에 해당하는 회전수 이상이 아니면 점화시기 지연과 아이들 속도 제어하여 유량을 감소하면서 주제어를 수행하는 단계와; 상기 단계에서 엔진 회전수 편차가 고위험 급발진 판정치에 해당하는 회전수 이상이면 연료공급을 차단하고 주제어를 수행하는 단계로 이루어짐을 특징으로 한다.In order to achieve the above object, the present invention includes the steps of determining whether the rapid start and control conditions are satisfied after starting the engine; Detecting engine speed and determining whether the detected engine speed is equal to or higher than the speed of the engine speed start when the rapid start control condition is satisfied in the step; If the actual engine speed detected in the step is equal to or more than the rapid start determination speed, the engine speed deviation between the detected actual engine speed and the target speed arbitrarily set according to the water temperature is calculated, and the calculated engine speed deviation is high risk. Determining whether or not the rotational speed corresponding to the sudden start determination value is equal to or greater than; Performing main control while reducing the flow rate by controlling the ignition timing and idling speed if the engine speed deviation is not greater than the speed corresponding to the high risk sudden start determination value; In the above step, if the engine speed deviation is higher than the speed corresponding to the high risk sudden start determination value, the fuel supply is characterized in that the step of performing the main control.

그러므로 본 발명에 의하면 엔진 시동후 급발진 조건을 판단하여 급발진 조건이면, 엔진 회전수를 감지하여 이 감지된 엔진 회전수가 급발진에 해당하는 회전수 이하이면 점화시기 지연과 아이들 속도 제어로 유량의 감소를 수행하고, 상기 감지된 엔진 회전수가 급발진에 해당하는 회전수 이상으로 판단되면 연료공급을 차단하여 엔진이 정지되도록 함으로써, 엔진 시동후 급발진을 사전에 방지하게 되는 것이다.Therefore, according to the present invention, if the rapid start condition is determined after starting the engine, if the sudden start condition is detected, the engine speed is sensed and if the detected engine speed is less than the speed corresponding to the rapid start, the ignition timing is delayed and the flow rate is reduced by the idle speed control. When the detected engine speed is determined to be higher than the speed corresponding to the rapid start, the engine is stopped by stopping the fuel supply, thereby preventing the sudden start after the engine is started.

이하 본 발명의 바람직한 실시예를 첨부되는 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

도 1 은 본 발명에 이용되는 급발진 방지 장치의 개략적인 블럭도로서, 차량의 점화(시동)유무를 감지하는 점화스위치(10)와; 상기 점화스위치(10)로부터 시동시 자동변속기의 변속위치를 감지하는 쉬프트 레버 위치센서(11)와; 상기 쉬프트 레버 위치센서(11)로 부터 감지된 위치에 따라 스로틀 밸브의 위치를 감지하는 스로틀 위치센서(12)와; 상기 스로틀 위치 센서(12)로 부터 스로틀 밸브의 위치 감지시 브레이크가 온 상태인가를 감지하는 브레이크 스위치(13)와; 상기 브레이크 스위치(13)의 온 상태시 엔진 회전수를 감지하는 엔진 회전수 센서(14)와; 상기 센서들로부터 감지된 신호를 기설정된 프로그램에 의하여 급발진 조건 및 엔진 회전수가 고위험 급발진 판정치인가를 판단하고, 이 판단된 상태에 해당하는 제어신호를 출력하는 전자제어장치(15)와; 상기 전자제어장치(15)에서 출력되는 제어신호에 의하여 연료를 차단하는 연료공급 차단부(16)와; 점화시기를 제어하는 점화시기 제어부(17)와; 아이들 속도를 제어하여 유량을 감소하는 아이들 속도 제어부(18)로 구성하게 된다.1 is a schematic block diagram of a sudden start and prevention device used in the present invention, an ignition switch 10 for detecting the presence or absence (ignition) of the vehicle; A shift lever position sensor 11 for detecting a shift position of an automatic transmission when starting from the ignition switch 10; A throttle position sensor 12 for detecting the position of the throttle valve according to the position detected by the shift lever position sensor 11; A brake switch 13 for detecting whether the brake is on when the position of the throttle valve is detected from the throttle position sensor 12; An engine speed sensor (14) for detecting engine speed when the brake switch (13) is in an on state; An electronic control device (15) for determining whether the sudden start condition and the engine speed are the high risk sudden start determination value based on a preset program, and outputting a control signal corresponding to the determined state; A fuel supply cut-off unit 16 which cuts off fuel by a control signal output from the electronic controller 15; An ignition timing controller 17 for controlling the ignition timing; The idle speed control unit 18 is configured to reduce the flow rate by controlling the idle speed.

이와 같이 구성된 급발진 방지 장치는 도 2 에 도시한 바와 같이, 먼저 전자제어장치(15)의 메모리(도시되지 않음)에 급발진에 대한 정보 즉 급발진 판정 회전수(Ne-q),목표 엔진 회전수(Ne-t), 고위험 급발진 판정치(Nstep)를 미리 설정(저장)해 놓게 된다(단계20).As shown in FIG. 2, the sudden start prevention device configured as described above has information about sudden start, that is, the sudden start speed (Ne-q) and the target engine speed ( Ne-t), the high risk sudden oscillation judgment value Nstep is set (stored) in advance (step 20).

이어서 상기 메모리에 차량을 시동후 브레이크 스위치″온″, 변속 ″전진″ ″후진″, 스로틀 위치 센서값을 엔진 정지 회전수 감지시 스로틀 위치 센서값 이하로 설정하여 급발진 제어 조건을 저장해 놓게 된다(단계21).Subsequently, after starting the vehicle in the memory, the brake switch ″ on ″, the shift ″ forward ″ ″ reverse ″, and the throttle position sensor value are set below the throttle position sensor value when the engine stop rotation speed is sensed to store the sudden start control condition (step) 21).

상기와 같이 급발진을 판정할 제어 조건 및 급발진 제어조건을 설정하여 놓은 상태에서, 점화스위치(10)를 통해서 엔진 시동이 걸리게 되면, 상기 전자제어장치(15)에서는 브레이크 스위치(13)를 통해서 ″온″, 쉬프트 레버 위치센서(11)로 부터 변속 ″전진″, 스로틀 위치 센서(12)로 부터 감지된 스로틀 위치 센서값이 엔진정지 회전수 감지시 해당하는 스로틀 위치 센서값 이하인 급발진 제어조건인가를 판단하게 된다(단계22).As described above, when the engine is started through the ignition switch 10 in a state in which the control condition and the sudden start control condition are set, the electronic control device 15 turns on the brake switch 13 through the brake switch 13. ″, Shift ″ forward ″ from shift lever position sensor 11, throttle position sensor value detected from throttle position sensor 12 is a sudden start control condition that is equal to or less than the corresponding throttle position sensor value upon detection of engine stop rotation speed. (Step 22).

이때 판단결과 조건이 급발진 제어 조건에 해당하면, 상기 전자제어장치(15)에서는 엔진 회전수 센서(14)를 통해서 현재 엔진 회전수(Ne)를 감지하게 되고(단계23), 이어서 상기 전자제어장치(15)에서는 상기 감지된 엔진 회전수(Ne)가 급발진 판정 회전수(Ne-q)이상에 도달하였는가를 판단하게 된다(단계24).At this time, if the determination result condition is a sudden start control condition, the electronic control device 15 detects the current engine speed Ne through the engine speed sensor 14 (step 23), and then the electronic control device In (15), it is determined whether the detected engine speed Ne has reached or exceeded the sudden start determination speed Ne-q (step 24).

따라서 상기 감지된 엔진 회전수(Ne)가 급발진 판정 회전수(Ne-q)이상에 도달하였으면 상기 전자제어장치(15)에서는 현재 엔진 회전수가 높게 상승하고 있는 것으로 판단하여 상기 감지된 엔진 회전수(Ne)로 부터 목표 엔진 회전수(Ne-t)를 감산하여 엔진 회전수 편차(ΔNe)를 산출한다(단계25).Therefore, if the detected engine speed Ne reaches more than the rapid start determination speed Ne-q, the electronic controller 15 determines that the current engine speed is rising to the high engine speed ( The engine speed deviation ΔNe is calculated by subtracting the target engine speed Ne-t from Ne) (step 25).

이어서 상기 전자제어장치(15)에서는 상기 산출된 엔진 회전수 편차(ΔNe)가 임의로 설정된 고위험 급발진 판정치(Nstep) 이상인가를 판단하게 되고(단계26), 이때 판단결과 엔진 회전수 편차(ΔNe)가 고위험 급발진 판정치(Nstep)이상이 아니면, 상기 전자제어장치(15)에서는 급발진이 쉽게 발생하지 않는 것으로 판단하여 점화시기 제어부(17)의 점화코일을 제어하여 점화시기를 지연시킴과 아울러, 아이들 속도 제어부(18)를 제어하여 유량 감소 제어하게 된다(단계27).Subsequently, the electronic controller 15 determines whether or not the calculated engine speed deviation ΔNe is greater than or equal to a randomly set high risk sudden start determination value Nstep (step 26). In this case, the engine speed deviation ΔNe is determined. Is not higher than the high risk sudden start determination value Nstep, the electronic control device 15 determines that sudden start does not occur easily, and controls the ignition coil of the ignition timing controller 17 to delay the ignition timing and The speed control unit 18 is controlled to control the flow rate reduction (step 27).

그러나 상기 엔진 회전수 편차(ΔNe)가 고위험 급발진 판정치(Nstep)이상이면, 상기 전자제어장치(15)에서는 급발진이 발생될 우려가 있는 것으로 판단하여 연료 공급 차단부(16)를 제어하여 연료 공급을 차단하게 된다(단계28).However, if the engine speed deviation ΔNe is equal to or higher than the high risk sudden start determination value Nstep, the electronic controller 15 determines that there is a possibility that sudden start occurs, thereby controlling fuel supply cutoff 16 to supply fuel. Block (step 28).

이어서 상기 전자제어장치(15)에서는 기설정된 프로그램에 의하여 입력된 신호에 따라 운행에 관한 주제어를 수행함과 아울러(단계29), 엔진이 정지되었는가를 판단하게 되고(단계30), 이때 엔진이 정지상태가 아니면 엔진이 정지될 때까지 반복수행하고, 엔진이 정지되면 종료하게 된다(단계30).Subsequently, the electronic controller 15 performs a main control word according to a signal input by a predetermined program (step 29), and determines whether the engine is stopped (step 30). Otherwise, the process is repeated until the engine is stopped and terminated when the engine is stopped (step 30).

한편 상기 엔진 시동후 상기 급발진 조건중 스로틀 위치 센서값이 엔진 정지 회전수 감지시 스로틀 위치 센서값이 이상이거나 혹은 상기 급발진 제어 조건에 만족하더라도 감지된 회전수가 급발진 판정 회전수(Ne-q)이상이 되지 않으면 상기 전자제어장치(15)에서는 급발진이 발생하지 않는 것으로 판단하여 기설정된 프로그램에 의하여 입력된 신호에 따라 운행에 관한 주제어를 수행하게 된다On the other hand, when the throttle position sensor value of the sudden start condition is detected when the engine stop rotation speed is detected after the engine starts, the throttle position sensor value is abnormal or satisfies the sudden start control condition. If not, the electronic controller 15 determines that sudden oscillation does not occur, and performs a main control word for driving according to a signal input by a predetermined program.

이상에서 설명한 바와 같이 본 발명은 자동변속기 차량을 시동후 브레이크 스위치″온″ 변속 ″전진″ ″후진″, 스로틀 위치 센서값이 엔진 정지 회전수 감지시 스로틀 위치 센서값 이하 인 급발진 제어조건에 만족하게 되면, 엔진 회전수를 감지하여 이 감지된 엔진 회전수가 급발진에 해당하는 회전수 이하이면 점화 스위치의 점화시기를 지연함과 아울러 아이들 속도 제어를 수행하여 유량을 감소하고, 상기 감지된 엔진 회전수가 급발진에 해당하는 회전수 이상으로 판단되면 연료공급을 차단하여 엔진에 연료공급을 중단하도록 함으로써, 엔진 시동후 급발진 발생우려를 사전에 방지할 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention satisfies the sudden start control condition when the automatic transmission vehicle is braked, " on, " shifting, " forwarding, " reverse ", and the throttle position sensor value is less than or equal to the throttle position sensor value when the engine stop rotation speed is detected. When the engine speed is detected and the detected engine speed is less than the speed corresponding to the sudden start, the ignition timing of the ignition switch is delayed and the idle speed is controlled to decrease the flow rate, and the detected engine speed is suddenly started. If it is determined that the number of rotations corresponding to more than to stop the fuel supply to the engine by cutting off the fuel supply, it is to provide an effect that can prevent in advance the start-up concerns after starting the engine.
