Description
本發明係關於一種引擎運轉控制方法，尤指一種適用於具有啟動堵轉保護功能之引擎運轉控制方法。The invention relates to an engine operation control method, in particular to an engine operation control method suitable for a startup stall protection function.
目前市場上有使用一體化之啟動兼發電裝置(Integrated Starter and Generator，以下簡稱ISG)，用以增加機車之節能效果，其並具備有怠速熄火與再啓動之功能。由於啟動兼發電裝置(ISG)整合起動引擎之功能與引擎發動後之發電功能，使控制單元要做的控制與保護變的相對複雜。At present, an integrated starter and generator (ISG) is used on the market to increase the energy saving effect of the locomotive, and it has the functions of idling and restarting. The control and protection of the control unit is relatively complicated due to the function of the start-up and power generation unit (ISG) integrated starter engine and the power generation function after the engine is started.
此外，由一體式啟動兼發電裝置提供旋轉動能起動引擎時，可能遭遇到起動力量不足無法通過壓縮區間所產生的阻力，因而無法起動引擎，欲克服此問題，已有在引擎構造中加入減壓裝置之引擎，其減壓裝置可為單向式減壓裝置，可於曲軸反轉時一特定角度時減少汽缸壓力。In addition, when the rotary kinetic energy starter engine is provided by the integrated starter and power generation device, the engine may not be able to start the engine due to insufficient starting force and the resistance generated by the compression section. To overcome this problem, decompression has been added to the engine structure. The engine of the device, the pressure reducing device of which may be a one-way pressure reducing device, can reduce the cylinder pressure at a certain angle when the crankshaft is reversed.
所謂引擎減壓裝置，一般應用於引擎活塞之壓縮行程中洩漏部分氣體壓力以降低引擎阻抗，請參閱圖1係曲軸角度位置與啓動兼發電裝置之起動阻抗比較圖。如圖所示，縱軸座標表示啓動兼發電裝置正轉之起動阻抗，橫軸座標表示曲軸旋轉角度，本實施例係採用四衝程引擎之工作原理，其依據汽缸內活塞移動的位置來區分，因此每隔180度依序到達一次上死點(T.D.C)或下死點(B.D.C)之位置，而由0度開始在每個區間內依序分為動力、排氣、進氣、壓縮四個工作行程，所以一次循環其曲軸係旋轉720度。其中，一般情況下，在壓縮行程中且減壓裝置未開啓時，起動阻抗相對曲軸角度所繪製出的曲線將會如X曲線所示；然而，在壓縮行程中且離心式減壓裝置開啓時，起動阻抗相對曲軸角度所繪製出的曲線將會如Y曲線所示，在壓縮行程中且單向式減壓裝置有作用時，起動阻抗相對曲軸角度所繪製出的曲線將會如Z曲線所示，在360度左右兩邊各有一較小之阻抗係為引擎閥機構之阻抗。The so-called engine pressure reducing device is generally applied to leak the partial gas pressure in the compression stroke of the engine piston to reduce the engine impedance. Please refer to FIG. 1 for a comparison of the crank angle position and the starting impedance of the starting and power generating device. As shown in the figure, the vertical axis coordinate indicates the starting impedance of the starting and power generating device forward rotation, and the horizontal axis coordinate indicates the cranking angle. In this embodiment, the working principle of the four-stroke engine is adopted, which is distinguished according to the position of the piston movement in the cylinder. Therefore, the position of top dead center (TDC) or bottom dead center (BDC) is sequentially reached every 180 degrees, and is divided into four parts: power, exhaust, intake, and compression in each interval starting from 0 degrees. The working stroke, so the cycle of the crankshaft is rotated 720 degrees. Wherein, in general, during the compression stroke and when the pressure reducing device is not turned on, the curve drawn by the starting impedance with respect to the crank angle will be as shown by the X curve; however, during the compression stroke and the centrifugal pressure reducing device is turned on. The curve drawn by the starting impedance with respect to the crank angle will be as shown by the Y curve. When the compression stroke is used and the one-way decompression device is active, the curve of the starting impedance relative to the crank angle will be like the Z curve. It is shown that there is a small impedance on both sides of 360 degrees which is the impedance of the engine valve mechanism.
目前現有之啟動兼發電裝置(ISG)在反轉達到預停位置後再正轉時，若有外力堵住，或因無法克服壓縮壓力持續正轉，造成無法順利起動引擎時，會進行馬達堵轉保護，進而停止驅動，等待使用者再下達起動命令後重新倒轉至預停位置，再次重新執行正轉起動。此方式需較較大的正轉扭力與較多助跑距離正轉，用以增加慣性，克服壓縮區間的阻力，也可能因為電池電壓較低時，導致驅動力不足，難以正轉時越過壓縮上死點，如此會造成車輛需要更換電池或再對電池充電，才能再度啟動引擎；既增加維修需求，也造成使用者困擾，並非十分理想，尚有改善的空間。At present, when the existing start-up and power generation unit (ISG) is rotated forward after the reverse rotation reaches the pre-stop position, if there is external force blocking, or if the compression pressure cannot be overcome and the forward rotation is continued, the engine may be blocked when the engine cannot be started smoothly. Turn the protection, and then stop the drive, wait for the user to release the start command and then re-invert to the pre-stop position, and re-execute the forward rotation start again. This method requires a larger forward torque and a larger running distance to increase the inertia, overcome the resistance of the compression zone, or may cause insufficient driving force when the battery voltage is low, and it is difficult to cross the compression when it is rotated forward. Dead point, this will cause the vehicle to need to replace the battery or recharge the battery, in order to restart the engine; not only increase the maintenance requirements, but also cause user confusion, not very ideal, there is room for improvement.
發明人緣因於此，本於積極發明創作之精神，亟思一種可以解決上述問題之「引擎運轉控制方法」，幾經研究實驗終至完成本發明Because of this, in the spirit of active invention and creation, I thought about an "engine operation control method" that can solve the above problems. After several research experiments, I completed the invention.
由於啟動兼發電裝置直接正轉可能會因少數特例正轉起動失敗，如引擎拆裝維修後使得單向式減壓裝置沒有正常開啟，可能會使直接正轉失敗，或有機械系統之損壞；甚至機械結構卡住時，可能正轉、反轉皆會堵住無法運轉。在正常狀態下，反轉不會遭遇壓縮壓力，故反轉特定角度開啟單向式減壓裝置應當都可順利進行，除非機械結構出現故障或有外力卡住曲軸，才可能導致反轉堵轉，本發明之設計若反轉時遭遇堵轉，則停止反轉驅動，回到等待起動訊號，才可重新再嘗試起動。因此，本發明之主要目的係提供一種引擎運轉控制方法，能在啟動引擎之流程中設計反轉堵轉之判斷與堵轉保護。Since the direct forward rotation of the start-up and power generation device may fail due to a few special cases, if the one-way pressure reducing device is not normally opened after the engine is disassembled and repaired, the direct forward rotation may fail or the mechanical system may be damaged; Even when the mechanical structure is stuck, it may block and reverse. Under normal conditions, the reversal will not encounter the compression pressure, so the reverse direction of the specific angle to open the one-way decompression device should be smooth, unless the mechanical structure fails or there is an external force stuck to the crankshaft, it may lead to reverse rotation If the design of the present invention encounters a stall when reversing, the reverse driving is stopped, and the waiting for the start signal is returned to restart the attempt. Therefore, the main object of the present invention is to provide an engine operation control method capable of designing a reverse blocking judgment and a stall protection in a process of starting an engine.
此外，當啟動兼發電裝置直接驅動曲軸正轉起動中，經過一特定時間，曲軸不再正轉，即引擎未啟動成功，則判定為堵轉。因啟動兼發電裝置在堵轉時若持續驅動正轉，可能會有燒毀的疑慮，故停止正轉驅動，若此時使用者仍然按著起動按鈕，為使引擎還有再次起動之機會，會進行反轉一特定角度使單向式減壓裝置開啟，反轉後再進行正轉起動引擎。若第二次正轉也發生堵轉，則再次反轉一特定角度使單向式減壓裝置開啟，並回到等待重新一次接收引擎起動訊號，再次直接啟動正轉增加引擎起動順暢性，故本發明之引擎運轉控制方法可於每次起動時，不需倒轉，省下驅動反轉到定位的步驟，可縮短起動時間與增加起動成功機會之方法。In addition, when the starting and power generating device directly drives the crankshaft forward rotation start, after a certain time, the crankshaft no longer rotates positively, that is, if the engine is not started successfully, it is determined to be stalled. If the start-up and power-generating device continues to drive forward when it is blocked, there may be doubts about burning, so stop the forward drive. If the user still presses the start button, the engine will have a chance to start again. Reverse the specific angle to open the one-way decompression device, and then reverse the engine to start the engine. If the second forward rotation also occurs, the reverse direction is reversed again, the one-way decompression device is turned on, and it is returned to wait for the engine start signal to be received again, and the forward rotation is directly started to increase the engine start smoothness. The engine operation control method of the invention can eliminate the need of reverse rotation every time starting, and save the step of driving reverse to positioning, which can shorten the starting time and increase the chance of successful starting.
為達成上述之目的，本發明之引擎運轉控制方法係使用於一機車上，該機車組設有一電池、一計時器、一具有一曲軸與一單向式減壓裝置之引擎、一用以驅動引擎正轉或反轉之啟動兼發電裝置、一用以偵測曲軸角度之角度感測裝置及一用以控制啓動兼發電裝置之驅動控制裝置，該驅動控制裝置具有一引擎運轉控制方法。In order to achieve the above object, the engine operation control method of the present invention is used on a locomotive provided with a battery, a timer, an engine having a crankshaft and a one-way decompression device, and a drive for driving A start-and-go power generation device for forward or reverse rotation of the engine, an angle sensing device for detecting a crank angle, and a drive control device for controlling the start-up and power generation device, the drive control device having an engine operation control method.

After the reversal to the specific angle, the method may further include (F1) determining whether the crankshaft is not reversed after a certain time of the first reversal.

Turn, if yes, go back to step (A), if not, go back to step (J). Thereby, the invention can design the reverse blocking mechanism and the stall protection in the process of starting the engine, and if the reverse stall occurs, it will not be reversed, and return to re-determine whether the engine start signal is received. And act again.

請參閱圖4係本發明第一較佳實施例引擎起動控制方法之收到起動訊號之流程，並請一併參閱圖3。在本實施例中，驅動控制裝置21之收到起動訊號之引擎起動控制方法依序為：(A)該機車之電源開啟，判斷是否收到一引擎起動訊號，若是則執行步驟(B)，若不是則回到步驟(A)；(B)驅動曲軸31第一次正轉；(C)判斷引擎30是否成功啟動，若是則執行步驟(D)，若不是則執行步驟(E)；(D)停止驅動，啓動兼發電裝置23進入發電模式；(E)判斷曲軸31第一次正轉一特定時間後是否不再正轉，若是則執行步驟(F)，若不是則回到步驟(B)；(F)驅動曲軸31第一次反轉，判斷曲軸31第一次反轉是否反轉至一特定角度，若是則執行步驟(G)，若不是則回到步驟(F)；(G)驅動曲軸31第二次正轉；(H)判斷引擎30是否成功啟動，若是則執行步驟(D)，若不是則執行步驟(I)；(I)判斷曲軸31第二次正轉一特定時間後是否不再正轉，若是則執行步驟(J)，若不是則回到步驟(G)；以及(J)驅動曲軸31第二次反轉，判斷曲軸31第二次反轉是否反轉至一特定角度，若是則回到步驟(A)，若不是則回到步驟(J)。Please refer to FIG. 4 , which is a flow of receiving the start signal of the engine start control method according to the first preferred embodiment of the present invention, and please refer to FIG. 3 together. In this embodiment, the engine start control method for receiving the start signal by the drive control device 21 is: (A) the power of the locomotive is turned on, determining whether an engine start signal is received, and if yes, performing step (B), If not, return to step (A); (B) drive the crankshaft 31 for the first forward rotation; (C) determine whether the engine 30 is successfully started, if yes, execute step (D), if not, execute step (E); D) stopping the driving, starting the power generating device 23 to enter the power generating mode; (E) determining whether the crankshaft 31 is not rotating forward after the first forward rotation for a certain period of time, if yes, executing step (F), if not, returning to the step ( B); (F) drive the crankshaft 31 for the first inversion, determine whether the first reversal of the crankshaft 31 is reversed to a specific angle, and if so, execute step (G), if not, return to step (F); G) driving the crankshaft 31 for the second forward rotation; (H) determining whether the engine 30 is successfully started, if yes, executing step (D), if not, executing step (I); (I) determining that the crankshaft 31 is rotating forward for the second time. Whether it is no longer forward after a certain time, if yes, execute step (J), if not, return to step (G); and (J) drive the crankshaft 31 for the second inversion It is determined whether the second reversal of the crankshaft 31 is reversed to a specific angle, and if so, returns to the step (A), and if not, returns to the step (J).
在本實施例中，引擎30之起動訊號係指下述其一：引擎控制單元33傳來之起動訊號、啓動按鈕11被按壓之訊號及油門啓動裝置12被啓動之訊號。其中，油門啓動裝置12可為油門線設有一微動開關，當油門線被驅動時，會觸動該微動開關，或是油門把手設有一感知器，可偵測油門把手是否被旋轉，微動開關或油門把手感知器皆可作為油門啓動裝置12。In the present embodiment, the start signal of the engine 30 refers to one of the following: the start signal transmitted from the engine control unit 33, the signal that the start button 11 is pressed, and the signal that the throttle start device 12 is activated. The throttle starting device 12 can be provided with a micro switch for the throttle line. When the throttle line is driven, the micro switch is activated, or the throttle handle is provided with a sensor to detect whether the throttle handle is rotated, the micro switch or the throttle A handle sensor can be used as the throttle actuating device 12.
此外，在本實施例中，引擎控制單元33可以控制引擎30使其具有怠速熄火功能。上述特定時間可為0.045秒，其作為判斷驅動曲軸31正轉是否堵轉之時間，若曲軸31正轉超過此時間就不再正轉，則判定為堵轉，停止驅動。又，上述之特定角度其範圍可介於40~140度，作為引擎30起動時確保其成功觸發單向式減壓裝置32。Further, in the present embodiment, the engine control unit 33 can control the engine 30 to have an idle stop function. The specific time may be 0.045 seconds, which is a time for judging whether or not the forward rotation of the crankshaft 31 is blocked. If the crankshaft 31 does not rotate normally after the normal rotation exceeds the time, it is determined that the rotation is stopped and the driving is stopped. Further, the specific angle described above may range from 40 to 140 degrees to ensure that the unidirectional pressure reducing device 32 is successfully triggered when the engine 30 is started.
藉此，本實施例於步驟(E)中，設有判斷是否正轉堵轉之機制，當啟動兼發電裝置23直接驅動曲軸31正轉起動中，經過一特定時間，曲軸31不再正轉，即表示引擎30未啟動成功，則判定為堵轉。因啟動兼發電裝置23在堵轉時若持續驅動正轉，可能會有燒毀的疑慮，故停止正轉驅動，若此時仍有起動訊號，為使引擎30還有再次起動之機會，會進行反轉一特定角度使單向式減壓裝置32開啟，反轉後再進行正轉起動引擎30。於步驟(G)中，也設有判斷是否正轉堵轉之機制，若第二次正轉也發生堵轉，則再次反轉一特定角度使單向式減壓裝置32開啟，並回到等待重新一次判斷是否有收到起動訊號，再次直接啟動正轉增加引擎起動順暢性。因此，故本實施例可於每次起動時，不需倒轉，省下驅動反轉到定位的步驟，可縮短引擎30之起動時間與增加起動成功機會之方法，且能在啟動引擎30之流程中設計正轉堵轉之判斷機制與堵轉保護。Therefore, in the step (E), the present embodiment is provided with a mechanism for judging whether or not the forward rotation is blocked. When the starting and power generating device 23 directly drives the crankshaft 31 to rotate forward, the crankshaft 31 is no longer rotated after a certain period of time. , that is, if the engine 30 is not successfully started, it is determined to be blocked. If the start-up and power-generating device 23 continues to drive the forward rotation during the stalling, there may be doubts about burning, so the forward-rotation drive is stopped. If there is still a start signal at this time, the engine 30 may have a chance to restart again. The one-way decompression device 32 is turned on by inverting a specific angle, and the forward rotation start engine 30 is performed after the reversal. In the step (G), a mechanism for judging whether or not the positive rotation is blocked is also provided. If the second forward rotation is also blocked, the specific angle is reversed again to open the one-way decompression device 32, and return to Waiting to judge again whether there is a start signal, and directly start the forward rotation to increase the engine start smoothness. Therefore, in this embodiment, the step of reversing the drive to the positioning can be omitted at each startup, and the method of shortening the start time of the engine 30 and increasing the chance of successful startup can be shortened, and the process of starting the engine 30 can be started. The judgment mechanism and stall protection of the design forward rotation and blocking.
請參閱圖5係本發明第二較佳實施例引擎起動控制方法之收到起動訊號之流程，並請一併參閱圖3。第二實施例與第一實施例之系統架構完全相同，且整體引擎起動控制方法大致相同，其差異僅在於第二實施例較第一實施例增加了步驟(F1)與(J1)之判斷機制，亦即在步驟(F)驅動曲軸31第一次反轉，沒有反轉至特定角度後，更包括有(F1)判斷曲軸31第一次反轉一特定時間後是否不再反轉，若是則回到步驟(A)，若不是則回到步驟(F)。另，也在步驟(J)驅動曲軸31第二次反轉，沒有反轉至特定角度後，更包括有(J1)判斷曲軸31第二次反轉一特定時間後是否不再反轉，若是則回到步驟(A)，若不是則回到步驟(J)。Please refer to FIG. 5, which is a flow chart of receiving a start signal by the engine start control method according to the second preferred embodiment of the present invention, and please refer to FIG. 3 together. The second embodiment is identical to the system architecture of the first embodiment, and the overall engine start control method is substantially the same, the only difference being that the second embodiment adds the judgment mechanisms of steps (F1) and (J1) to the first embodiment. That is, in the step (F), the crankshaft 31 is driven to reverse for the first time, and after the reverse rotation to a specific angle, it is further included (F1) to determine whether the crankshaft 31 is not reversed after a certain time of the first time of reversal. Then return to step (A), and if not, return to step (F). In addition, the second reversal of the crankshaft 31 is also driven in the step (J). After the reversal to a specific angle, it is further included (J1) to determine whether the crankshaft 31 is not reversed after a second time of reversal for a certain period of time. Then return to step (A), and if not, return to step (J).
藉此，第二實施例除了具有第一實施例之功能之外，且能在啟動引擎30之流程中增加反轉堵轉之判斷機制與堵轉保護，在正常狀態下，曲軸31反轉不會遭遇壓縮壓力，故反轉特定角度開啟單向式減壓裝置23應當都可順利進行，除非機械結構出現故障或有外力卡住曲軸31，才可能導致反轉堵轉，本實施例之設計若反轉時遭遇堵轉，則停止反轉驅動，回到等待起動訊號，才可重新再嘗試起動。Thereby, in addition to the function of the first embodiment, the second embodiment can increase the judgment mechanism of the reverse blocking and the stall protection in the process of starting the engine 30. In the normal state, the crankshaft 31 is reversed. The compression pressure will be encountered, so that the one-way decompression device 23 can be smoothly operated to reverse the specific angle. Unless the mechanical structure is broken or an external force is stuck on the crankshaft 31, the reverse rotation can be caused. The design of this embodiment If the reverse rotation encounters a stall, stop the reverse drive and return to the waiting start signal before attempting to start again.

The third embodiment is identical to the system architectures of the first and second embodiments, and the third embodiment is substantially the same as the overall engine start control method of the second embodiment, except that the second embodiment is added to the second embodiment. The judgment mechanism of whether the start signals of steps (B1) to (B3) and (G1) to (G3) are closed.
如圖6A所示，於步驟(B)之後，接著(B1)判斷引擎起動訊號是否關閉，若是則執行步驟(B2)，若不是則執行步驟(C)；(B2)驅動曲軸31反轉，判斷曲軸31反轉是否反轉至一特定角度，若是則回到步驟(A)，若不是則執行步驟(B3)；以及(B3)判斷曲軸31反轉一特定時間後是否不再反轉，若是則回到步驟(A)，若不是則回到步驟(B2)。As shown in FIG. 6A, after step (B), it is next (B1) to determine whether the engine start signal is off, and if so, execute step (B2), if not, execute step (C); (B2) drive the crankshaft 31 to reverse. It is judged whether the reverse rotation of the crankshaft 31 is reversed to a specific angle, and if yes, returning to step (A), if not, executing step (B3); and (B3) determining whether the crankshaft 31 is not reversed after a certain time of reversal, If yes, return to step (A), and if not, return to step (B2).
如圖6B所示，於步驟(G)之後，接著(G1)判斷引擎起動訊號是否關閉，若是則執行步驟(G2)，若不是則執行步驟(H)；(G2)驅動曲軸31反轉，判斷曲軸31反轉是否反轉至一特定角度，若是則回到步驟(A)，若不是則執行步驟(G3)；以及(G3)判斷曲軸31反轉一特定時間後是否不再反轉，若是則回到步驟(A)，若不是則回到步驟(G2)。As shown in FIG. 6B, after step (G), it is next (G1) to determine whether the engine start signal is off, and if so, execute step (G2), if not, execute step (H); (G2) drive crankshaft 31 reverse. It is determined whether the reverse rotation of the crankshaft 31 is reversed to a specific angle, and if yes, returning to step (A), if not, executing step (G3); and (G3) determining whether the crankshaft 31 is not reversed after a certain period of time is reversed. If yes, return to step (A), and if not, return to step (G2).
藉此，第三實施例除了具有第一實施例與第二實施例之功能之外，且第三實施例為求每次啟動兼發電裝置23於第一次直接正轉或第二次直接正轉驅動曲軸31起動都可以順利啟動引擎30，若第一次直接正轉或第二次正轉起動過程中，引擎30尚未啟動時，使用者停止起動訊號，此時系統會直接反轉一特定角度使單向式減壓裝置32開啟，確保下次起動時能夠有減壓之效果，以最短時間直接正轉起動引擎30。Thereby, the third embodiment has the functions of the first embodiment and the second embodiment, and the third embodiment is for the first direct forward rotation or the second direct positive operation for each startup and power generation device 23 When the crankshaft 31 is started, the engine 30 can be smoothly started. If the engine 30 has not been started during the first direct forward rotation or the second forward rotation, the user stops the start signal, and the system directly reverses the specific one. The angle causes the one-way decompression device 32 to be opened, ensuring that the decompression effect can be achieved at the next start, and the engine 30 is directly rotated forward in the shortest time.
