Description

커먼레일 엔진의 시동 제어방법{Start Control Method of Common Rail Engine}Start Control Method of Common Rail Engine

본 발명은 커먼레일 엔진의 시동 제어방법에 관한 것으로서, 보다 상세하게는 엔진의 고장시에는 엔진의 시동성 향상을 위한 제어를 중지하여 엔진을 보호할 수 있도록 하는 기술에 관한 것이다.The present invention relates to a start control method for a common rail engine, and more particularly, to a technology for protecting the engine by stopping the control for improving the startability of the engine in case of engine failure.

종래 커먼레일 엔진의 시동은 엔진회전수, 냉각수온, 공기밀도에 의해서 엔진의 시동토크를 계산하고, 이와 같은 시동토크를 발생시키는 데에 필요한 연료분사량을 결정하도록 하였다.In the conventional common rail engine, the starting torque of the engine is calculated based on the engine speed, the cooling water temperature, and the air density, and the fuel injection amount required to generate such starting torque is determined.

그러나, 엔진은 엔진의 노후, 엔진오일의 변질, 매우 낮은 대기온도, 자동변속기의 고장 등에 의해 실질적으로는 더 많은 시동토크가 필요한 경우가 많다. However, engines often require substantially more starting torque due to engine deterioration, engine oil deterioration, very low ambient temperature, failure of automatic transmission, and the like.

종래 상기한 바와 같이 엔진이 필요로 하는 시동토크에 영향을 주는 다양한 인자들을 고려하는 방법으로서, 정해진 시간 내에 엔진회전수가 시동완료로 판정될 수 있는 수준을 넘어서는지를 판단하고, 그렇지 못한 경우에는 추가할 시동토크를 계산하여 이를 적용함으로써, 커먼레일 엔진의 시동성을 크게 개선하도록 한 방법이 사용되었다.As described above, as a method of considering various factors affecting the starting torque required by the engine, it is determined whether the engine speed exceeds a level that can be determined as the start-up completion within a predetermined time. By calculating the starting torque and applying it, a method was used to greatly improve the startability of the common rail engine.

즉, 도 1에 도시된 바와 같이 엔진의 시동이 시작되면, 엔진회전수와 냉각수온 및 공기밀도를 입력 받아 엔진의 시동에 필요한 요구토크를 계산하여 이를 적용하는 단계(S501)를 수행하고, 정해진 시간 내에 엔진회전수가 시동이 걸린 것으로 판단할 수준에 이르렀는지를 판단하여 시동의 성공여부를 판단하는 단계(S502)를 두고, 위 단계의 판단 결과, 시동에 성공하지 못한 것으로 판단되는 경우에는 현재의 토크를 10% 더 증가시켜서 시동을 시도하고(S503), 다시 반복적으로 시동의 성공여부를 판단하여(S504), 반복적으로 시동이 이루어질 때까지 토크를 점차 증대시키는 것이다.That is, as shown in FIG. 1, when the engine starts, the engine torque, the coolant temperature, and the air density are input to calculate the required torque required for starting the engine (S501). In step S502, it is determined whether the engine speed has reached a level judged to have been started within the time, and it is determined whether the start is successful or not. Attempting to start by increasing the torque by 10% more (S503), and again it is determined whether or not the success of the start (S504), the torque is gradually increased until it is repeatedly started.

그런데, 오일링이 잘못 장착되어 피스톤과 실린더 사이에 끼인 경우나, 크랭크샤프트나 캠샤프트 혹은 타이밍벨트에 볼트나 금속조각 등이 떨어져 끼인 경우와 같이, 실질적으로 엔진에 고장이나 이상이 발생되어 그대로 시동을 걸어서는 엔진의 파손이 필연적인 경우에까지, 상기와 같이 시동을 걸기 위해 계속적으로 토크를 상승시키게 되면, 엔진이 크게 파손되게 되는 문제가 있다. However, if the oil ring is improperly mounted and caught between the piston and the cylinder, or the bolt or metal fragments are caught in the crankshaft, camshaft, or timing belt, the engine may actually start up and malfunction. In this case, if the torque is continuously increased to start the engine as described above, the engine is greatly damaged until the breakage of the engine is inevitable.

본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 그대로 시동을 걸게 되면 엔진의 파손이 필연적인 엔진의 고장이나 이상 발생시에는, 이를 감지하여 엔진의 시동을 걸기 위한 토크의 증대 작용을 중지 및 엔진을 정지시킴으로써, 엔진을 보호할 수 있도록 한 커먼레일 엔진의 시동 제어방법을 제공함에 그 목적이 있다.The present invention has been made in order to solve the problems described above, when starting the engine as it is, if the engine breakdown is inevitable failure or abnormality of the engine, it detects this and stops the increase in torque for starting the engine And a start control method for a common rail engine capable of protecting the engine by stopping the engine.

In the case of a failure as described above, it is possible to ensure smooth startability of the common rail engine.

도 2는 본 발명에 따른 커먼레일 엔진의 시동 제어방법을 설명한 순서도로서, 본 발명 실시예는 엔진의 시동시에, 소정시간(예컨대, 30ms) 이내에 엔진회전수변화량이 소정수준(예컨대, 30RPM) 이상인지 여부를 판단하는 회전수변화량판단단계(S101)와; 엔진의 시동시에, 소정시간(예컨대, 100ms) 이내에 엔진의 역회전이 있었는지를 판단하는 역회전판단단계(S102)와; 상기 회전수변화량판단단계(S101) 수행 결과, 엔진회전수변화량이 소정수준 이하인 경우 및 상기 역회전판단단계(S102) 수행 결과, 엔진의 역회전이 있었던 것으로 판단되는 경우에는 엔진의 고장으로 판단하는 고장판단단계(S103)를 포함하여 구성된다.2 is a flowchart illustrating a start control method of a common rail engine according to the present invention. In the embodiment of the present invention, the engine speed change amount is within a predetermined level (eg, 30 RPM) within a predetermined time (for example, 30 ms) when the engine is started. A rotation speed change amount determining step (S101) of determining whether or not the error is abnormal; A reverse rotation determination step (S102) of judging whether there has been reverse rotation of the engine within a predetermined time (for example, 100 ms) at the start of the engine; If the engine speed change amount is less than a predetermined level as a result of performing the rotation speed change amount determination step (S101), and if it is determined that the reverse rotation of the engine has occurred as a result of performing the reverse rotation determination step (S102), it is determined that the engine has failed. It is configured to include a fault determination step (S103).

상기 고장판단단계(S103)에서는, 엔진의 고장으로 판단된 경우, 엔진경고등을 점등하고, 연료분사를 금지하여 엔진을 정지시키도록 한다.In the failure determination step (S103), when it is determined that the engine has failed, the engine warning lamp is turned on and the fuel injection is prohibited to stop the engine.

상기 역회전판단단계(S102)는 상기 회전수변화량판단단계(S101) 직후에 수행하도록 하였다.The reverse rotation determination step (S102) was to be performed immediately after the rotation speed change amount determination step (S101).

즉, 상기 회전수변화량판단단계(S101) 수행 결과, 엔진회전수변화량이 30RPM이상이라고 판단되는 경우에도 상기 역회전판단단계(S102)를 수행하도록 한 것이다.That is, even when it is determined that the engine speed change amount is 30 RPM or more, as a result of performing the rotation speed change amount determination step S101, the reverse rotation determination step S102 is performed.

여기서, 상기 역회전판단단계(S102)는 최근 개발되어 상용화되어 있는 크랭크샤프트의 역회전 감지가 가능한 크랭크센서 또는 캠샤프트의 역회전 감지가 가능한 캠센서로부터 제공되는 신호를 이용한다.Here, the reverse rotation determination step (S102) uses a signal provided from a crank sensor capable of detecting the reverse rotation of the crankshaft or a cam sensor capable of detecting the reverse rotation of the camshaft, which has been recently developed and commercialized.

물론, 상기 회전수변화량판단단계(S101)를 수행하기 위해서도 상기 크랭크센서 또는 캠센서의 신호를 입력 받아 현재의 엔진회전수에 대한 정보를 얻도록 한다.Of course, in order to perform the rotation speed change amount determination step (S101), by receiving a signal of the crank sensor or the cam sensor to obtain information about the current engine speed.

한편, 상기 회전수변화량판단단계(S101) 이전에는, 엔진회전수, 냉각수온, 공기밀도를 기준으로 시동에 필요한 요구토크를 계산하는 기본토크계산단계(S91)와; 상기 계산된 요구토크를 적용한 후, 소정 시간(예컨대, 5초) 이내에 엔진회전수가 운전회전수(예컨대, 750RPM)에 도달하는지를 판단하는 최초시동성공판단단계(S92)와; 상기 최초시동성공판단단계(S92) 수행결과 시동이 완료되지 않은 것으로 판단되는 경우, 현재의 토크를 일정비율 증가시키는 토크증가단계(S93)를 차례로 수행한다.On the other hand, before the rotation speed change determination step (S101), the basic torque calculation step (S91) for calculating the required torque for starting on the basis of the engine speed, cooling water temperature, air density; An initial start success determination step (S92) of determining whether the engine speed reaches an operating speed (for example, 750 RPM) within a predetermined time (for example, 5 seconds) after applying the calculated required torque; When it is determined that the startup is not completed as a result of performing the initial start-up success determination step (S92), the torque increasing step (S93) of sequentially increasing the current torque is sequentially performed.

즉, 종래 커먼레일 엔진의 시동제어방법에서도 사용하는 기본토크계산단계(S91)를 수행하여 얻어진 요구토크로 엔진의 시동을 시도하고, 상기 최초시동성공판단단계(S92)에서 엔진의 시동이 성공한 것으로 판단되면, 엔진의 상태를 시동상태에서 운전상태로 전환하여, 시동 연료 계산을 중단하고 아이들 연료량 계산을 시작하며, 아울러 연료량 보정 등의 과정을 수행하도록 하고; 엔진의 시동이 실패한 것으로 판단되면, 상기 토크증가단계(S93)를 수행하도록 하는 것이다.That is, attempting to start the engine with the required torque obtained by performing the basic torque calculation step (S91) used in the start control method of the conventional common rail engine, and starting the engine in the initial start success determination step (S92). If it is determined, switch the state of the engine from the start state to the operating state, stop the start fuel calculation, start the idle fuel amount calculation, and perform a process such as fuel amount correction; If it is determined that the start of the engine has failed, it is to perform the torque increasing step (S93).

상기 토크증가단계(S93)에서는 현재토크를 10% 증가시켜서 엔진에 적용하도록 하고 있다.In the torque increase step (S93), the current torque is increased by 10% to apply to the engine.

한편, 상기 역회전판단단계(S102) 수행 결과, 엔진의 역회전이 없었던 것으로 판단되면, 소정 시간(예컨대, 3초) 이내에 엔진회전수가 상기 운전회전수에 도달하는지를 판단하는 시동성공판단단계(S94)를 수행하고; 상기 시동성공판단단계(S94)의 수행 결과, 시동이 완료되지 않은 것으로 판단되는 경우, 상기 토크증가단계(S93)를 반복적으로 수행하여, 커먼레일 엔진의 시동성을 향상시키도록 하는 것이다.On the other hand, if it is determined that there is no reverse rotation of the engine as a result of performing the reverse rotation determination step (S102), the start success determination step of determining whether the engine speed reaches the operating speed within a predetermined time (for example, 3 seconds) (S94) ); As a result of performing the start success determination step (S94), if it is determined that the start is not completed, the torque increase step (S93) is repeatedly performed to improve the startability of the common rail engine.

상기한 바와 같은 방법으로 커먼레일 엔진의 시동을 제어하게 되면, 상기 회전수변화량판단단계(S101) 및 역회전판단단계(S102)에 의해 엔진에 고장이나 문제가 있어서, 시동을 걸면 엔진의 파손이 불가피하게 되는 경우에, 이를 사전에 감지하여 엔진을 정지시키고 고장을 표시하도록 함으로써, 엔진을 보호하게 되고, 엔진의 고장이 아닌 경우에는 시동에 필요한 요구토크를 차츰 증가시키도록 하여 엔진의 원활한 시동성을 확보할 수 있도록 한다.When the start of the common rail engine is controlled by the method as described above, the engine is damaged or troubled by the rotation speed change amount determining step (S101) and the reverse rotation determining step (S102). If this is inevitable, the engine can be detected in advance to stop the engine and indicate a failure, thereby protecting the engine.In the case of non-engine failure, the required torque required for starting is gradually increased to smoothly start the engine. To be secured.
