Description
本發明係有關於一種車輛的電子控制器及控制方法，特別是有關於結合怠速控制單元之怠速控制功能的電子控制器及方法。The present invention relates to an electronic controller and control method for a vehicle, and more particularly to an electronic controller and method for combining an idle speed control function of an idle speed control unit.
請參閱圖1繪示先前技術之機車之怠速控制系統架構示意圖。先前技術中，為降低機車暫停的油耗並延長各元件的使用壽命，係於機車上配置一怠速控制系統，主要是於車輛的引擎架構下配置一怠速控制單元(Idle Stop Control Unit,ISU)15。此怠速控制單元15電性連接電子控制器10，並擷取電子控制器10與車輛各裝置感知器(如車速感測器11、油門開度感測器12、引擎轉速感測器13與引擎溫度感測器14)之間流傳的狀態數值，以在狀態數值符合怠速熄火條件時，立即停止供油單元16與點火單元17的動作，以使引擎熄火。然而，當車輛的油門開度超出原點預設值、或是離合器開關(配置於具打檔機制的車輛)動作時，怠速控制單元15即控制供油單元16、點火單元17與啟動馬達18運作，以啟動引擎。Please refer to FIG. 1 , which is a schematic structural diagram of an idle speed control system of a prior art locomotive. In the prior art, in order to reduce the fuel consumption of the locomotive suspension and prolong the service life of each component, an idle speed control system is arranged on the locomotive, mainly to configure an Idle Stop Control Unit (ISU) under the engine architecture of the vehicle. . The idle control unit 15 is electrically connected to the electronic controller 10, and captures the electronic controller 10 and the vehicle device sensors (such as the vehicle speed sensor 11, the throttle opening sensor 12, the engine speed sensor 13 and the engine). The state value circulating between the temperature sensors 14) immediately stops the operation of the oil supply unit 16 and the ignition unit 17 when the state value meets the idle speed extinguishing condition to extinguish the engine. However, when the accelerator opening of the vehicle exceeds the preset value of the origin or the clutch switch (disposed on the vehicle with the shifting mechanism) operates, the idle control unit 15 controls the oil supply unit 16, the ignition unit 17, and the starter motor 18 Operate to start the engine.
然而，怠速控制單元15必須額外配置與剪接線路，才能連接於電子控制器10與其它裝置之間，以擷取相關的狀態數值。若是配線作業有所失誤，將可能造成各電路、控制器與裝置因接線不良而損毀。其次，不論配線作業成功與否，皆會增加各電路與裝置的運作負擔，或是電力配置改變，從而影響車輛迴路的穩定性。其三，車輛進入怠速時，引擎、啟動馬達、相關裝置、單元或機構將被迫強制停止工作，此會造成各裝置與機構因運作不當而造成不可避免的磨損，反會降低裝置的使用壽命。其四，起動引擎時動作期間，怠速旁通閥因先前怠速的突發性停止作業，將導致閥門未能正確運作，導致引擎的進氣量異常，故無法以最佳空燃比進行引擎起動，如此反增加油耗量，同時損耗引擎且不利於啟動。However, the idle speed control unit 15 must be additionally configured and spliced to be connected between the electronic controller 10 and other devices to retrieve the associated state values. If there is a mistake in the wiring operation, the circuit, controller and device may be damaged due to poor wiring. Secondly, regardless of the success or failure of the wiring operation, the operation load of each circuit and device or the power configuration change may be increased, thereby affecting the stability of the vehicle circuit. Third, when the vehicle enters idle speed, the engine, starter motor, related equipment, unit or mechanism will be forced to stop working, which will cause inevitable wear and tear of each device and mechanism due to improper operation, which will reduce the service life of the device. . Fourth, during the operation of the engine, the idle bypass valve will stop operating due to the sudden idling of the previous idle speed, resulting in the valve not operating properly, resulting in abnormal engine intake, so the engine can not be started with the best air-fuel ratio. This increases fuel consumption and at the same time depletes the engine and is not conducive to startup.
因此，如何提供一個安全且能有效施行於車輛的引擎怠速控制技術，為廠商應思慮的問題。Therefore, how to provide a safe and effective engine idle speed control technology for the vehicle is a problem that manufacturers should consider.

The switch detecting unit 45 is connected to the idle function switching switch 35 and the micro control unit 46, and the micro control unit 46 is connected to the aforementioned sensing circuit 47 and the control circuit. The control circuit here is for controlling the restarting operation of the oil supply unit 22a, the ignition unit 22b, the engine 24, and the starter motor 23, hereinafter referred to as the oil supply control circuit 41, the ignition control circuit 42, the idle intake control circuit 43, and the motor. The control circuit 44 is restarted. The idle intake control circuit 43 is configured to assist the intake control of the engine 24 to assist the idle stop speed of the engine 24 during idle control, and to control the intake air amount when the engine 24 is restarted, thereby reducing the engine. The operation of 24 is worn out.
此等感知電路47用以接收車輛上配置的各種感測器、單元提供的車輛運轉資訊，如車速感知電路473用以感知車速感測器211提供的車速，油門開度感知電路472用以感知油門開度感測器212提供的油門開度，引擎轉速感知電路471用以感知引擎轉速感測器213提供引擎轉速。而於打檔式車輛中，離合器感知電路474用以感知離合器215的離合器操作桿2151是否動作，檔位感知電路475用以感知檔位機構214正處於那一個檔位。但不以上述感知電路為限，可更進一步提供用以感知氣缸提供的缸溫，感知曲軸節點開關提供的曲軸位置訊號，感知油泵繼電控制單元提供的觸發訊號，感知側支架節點開關提供的側支架位置訊號，感知怠速旁通閥提供的閥門開度的感知電路，此等感知電路47會將所接收的資訊與訊號轉換成微控制單元46能解析的資料型態。The sensing circuit 47 is configured to receive vehicle operating information provided by various sensors and units disposed on the vehicle. For example, the vehicle speed sensing circuit 473 is configured to sense the vehicle speed provided by the vehicle speed sensor 211, and the throttle opening sensing circuit 472 is configured to sense The accelerator opening degree provided by the accelerator opening sensor 212 is used to sense that the engine speed sensor 213 provides the engine speed. In the shift type vehicle, the clutch sensing circuit 474 is configured to sense whether the clutch operating lever 2151 of the clutch 215 is in motion, and the gear position sensing circuit 475 is configured to sense that the gear position mechanism 214 is in that gear position. However, not limited to the above sensing circuit, the cylinder temperature provided by the cylinder is sensed, the crankshaft position signal provided by the crankshaft switch is sensed, and the trigger signal provided by the oil pump relay control unit is sensed, and the sensing side bracket node switch provides The side bracket position signal senses a sensing circuit of the valve opening provided by the idle bypass valve, and the sensing circuit 47 converts the received information and signals into a data type that the micro control unit 46 can analyze.
當怠速功能切換開關35於開啟與關閉之間切換時，會提供不同的開關訊號，開關偵測單元45在取得開關訊號後，會因其訊號的不同以產生不同內容的開關狀態訊號，並傳輸開關狀態訊號至微控制單元46。微控制單元46會解析開關狀態訊號得知怠速功能切換開關35為開啟或關閉，以決定是否啟用怠速偵測模式。然，不論怠速功能切換開關35的狀態為何，微控制單元46皆會不斷接收上述各感測器提供的車輛運轉資訊。When the idle function switch 35 is switched between on and off, different switch signals are provided. After the switch signal is obtained, the switch detection unit 45 generates switch status signals of different contents due to different signals, and transmits The switch status signal is sent to the micro control unit 46. The micro control unit 46 will analyze the switch status signal to know that the idle function switch 35 is on or off to determine whether the idle detection mode is enabled. However, regardless of the state of the idle function switch 35, the micro control unit 46 continuously receives the vehicle operation information provided by each of the sensors.
當微控制單元46判定怠速功能切換開關35為開啟時，微控制單元46會接收上述各感測器提供的車輛運轉資訊，以判定上述的運轉資訊是否符合一引擎怠速熄火條件。舉例：引擎怠速熄火條件包括(1)電子控制器20判定車速感測器211所感測的車速(或是輪速)為零，即車輛處於靜止狀態。(2)油門開度感測器212感測的油門開度需達到一原點預設值，也就是騎乘者未催動油門。(3)引擎24為怠速狀態，即引擎轉速感測器213感測的引擎轉速需達到一怠速轉速以下，如引擎轉速每分鐘1700轉(1700RPM,1700 Rounds Per Minute)以下。When the micro control unit 46 determines that the idle function switch 35 is on, the micro control unit 46 receives the vehicle operation information provided by each of the sensors to determine whether the operation information meets an engine idle stop condition. For example, the engine idle stop condition includes (1) the electronic controller 20 determines that the vehicle speed (or the wheel speed) sensed by the vehicle speed sensor 211 is zero, that is, the vehicle is in a stationary state. (2) The throttle opening sensed by the accelerator opening sensor 212 needs to reach an original preset value, that is, the rider does not push the throttle. (3) The engine 24 is in an idle state, that is, the engine speed sensed by the engine speed sensor 213 needs to reach below an idle speed, such as an engine speed of 1700 rpm (1700 RPM, 1700 Rounds Per Minute) or less.
在車輛暫停期間，若運轉資訊符合上述的引擎怠速熄火條件，微控制單元46會等待一預設時間(如3秒)後，才透過控制電路以令上述的供油單元22a或點火單元22b，也就是油泵221、噴油嘴222、點火線圈223與火星塞224中至少任一者停止運行，或令供油單元22a或點火單元22b皆停止運行，以使得引擎24停止、熄火，如此，騎乘者停下車輛但未切斷車輛電力時，電子控制器20可在車輛於暫停期間內，令車輛自動進入怠速熄火模式，以降低車輛能量的耗損。During the vehicle suspension period, if the operation information meets the above-described engine idle-stop condition, the micro-control unit 46 waits for a predetermined time (for example, 3 seconds) before transmitting the control circuit to cause the above-described oil supply unit 22a or ignition unit 22b. That is, at least one of the oil pump 221, the fuel injector 222, the ignition coil 223, and the spark plug 224 is stopped, or the oil supply unit 22a or the ignition unit 22b is stopped, so that the engine 24 is stopped and turned off. When the occupant stops the vehicle but does not cut off the vehicle power, the electronic controller 20 can automatically enter the idling stop mode during the suspension period of the vehicle to reduce the energy consumption of the vehicle.
當使用者催促油門時，微控制單元46會透過油門開度感測器212而檢知油門開度超出原點預設值，微控制單元46會透過供油控制電路41驅動供油單元22a，即油泵221與噴油嘴222進行引擎供油作業；透過點火控制電路42驅動點火單元22b，即點火線圈223及火星塞224對供油單元22a之供油進行點火作業；透過馬達再啟動控制電路44觸發馬達繼電控制單元34，以使啟動馬達23取得啟動訊號及電瓶26提供的電力而開始運轉，藉此啟動引擎24，以令引擎24從怠速熄火模式下恢復成運作狀態。When the user urges the throttle, the micro control unit 46 detects that the throttle opening exceeds the preset value through the accelerator opening sensor 212, and the micro control unit 46 drives the oil supply unit 22a through the oil supply control circuit 41. That is, the oil pump 221 and the fuel injector 222 perform an engine oil supply operation; the ignition control unit 42 drives the ignition unit 22b, that is, the ignition coil 223 and the spark plug 224 perform ignition operation on the oil supply unit 22a; and the motor is restarted by the control circuit. 44 triggers the motor relay control unit 34 to cause the starter motor 23 to take the start signal and the power provided by the battery 26 to begin operation, thereby activating the engine 24 to return the engine 24 from the idle stop mode to an operational state.
更進一步，電子控制器20更包括一剎車燈控制電路32以連接微控制單元46與剎車燈33，當怠速熄火模式期間，微控制單元46會透過剎車燈控制電路32啟動剎車燈33，使剎車燈33在怠速熄火模式期間處於發光狀態，以提示後方來車的駕駛人，避免後方來車的追撞。Further, the electronic controller 20 further includes a brake light control circuit 32 for connecting the micro control unit 46 and the brake light 33. During the idle stop mode, the micro control unit 46 activates the brake light 33 through the brake light control circuit 32 to brake The lamp 33 is in a light-emitting state during the idle-stop mode to prompt the driver who is coming to the rear of the vehicle to avoid the collision of the rear vehicle.
此外，若騎乘者將怠速熄火模式誤認為車輛的完全熄火模式(引擎24及各相關元件停止運作狀態)，亦能操作啟動開關25進行車輛發動作業。此時，微控制單元46亦將啟動開關25提供的啟動訊號視為喚醒引擎24的控制訊號，微控制單元46會驅動供油單元22a與驅動點火單元22b進行點火作業，同時啟動馬達23運轉，藉此啟動引擎24，以令引擎24從怠速熄火模式下恢復成運作狀態。In addition, if the rider mistakes the idle stop mode for the complete flameout mode of the vehicle (the engine 24 and the related components are stopped), the start switch 25 can also be operated to perform the vehicle starting operation. At this time, the micro control unit 46 also regards the start signal provided by the start switch 25 as the control signal of the wake-up engine 24, and the micro control unit 46 drives the oil supply unit 22a and the drive ignition unit 22b to perform the ignition operation, and simultaneously starts the motor 23 to operate. The engine 24 is thereby activated to return the engine 24 from an idle stop mode to an operational state.
然而，當微控制單元46判定車輛狀態符合怠速熄火條件時，會透過上述的供油控制電路41、點火控制電路42與怠速進氣控制電路43，逐漸降低供油量、點火頻率與空氣進氣量，使得引擎和緩熄火，以逐漸令引擎進入靜止狀態，避免引擎的突發性停止而引發引擎無法修復的破壞性磨損。However, when the micro control unit 46 determines that the vehicle state conforms to the idle stop condition, the oil supply control circuit 41, the ignition control circuit 42, and the idle intake control circuit 43 are gradually lowered to gradually reduce the fuel supply amount, the ignition frequency, and the air intake. The amount is such that the engine is slowly extinguished to gradually bring the engine to a standstill, avoiding the sudden stop of the engine and causing destructive wear that the engine cannot repair.
請同時參閱圖4繪示本發明實施例之電子控制器20的第二種系統架構應用示意圖，請同時參閱圖2與圖3以利於了解。與圖2不同處在於，引擎24包括一檔位機構214與一離合器215，離合器215連接有一離合器操作桿2151，離合器操作桿2151設有一節點開關2152。檔位機構214設有一個以上檔位節點2142且包括空檔的檔位節點開關2143，為方便說明，係將空檔節點2141獨立而出。Please refer to FIG. 4 , which is a schematic diagram of a second system architecture application of the electronic controller 20 according to an embodiment of the present invention. Please refer to FIG. 2 and FIG. 3 for understanding. The difference from FIG. 2 is that the engine 24 includes a gear mechanism 214 and a clutch 215. The clutch 215 is coupled to a clutch operating lever 2151. The clutch operating lever 2151 is provided with a node switch 2152. The gear mechanism 214 is provided with more than one gear node 2142 and includes a neutral gear node switch 2143. For convenience of explanation, the neutral node 2141 is separated.
電子控制器20連接至上述的離合器操作桿2151的節點開關2152與檔位機構214的檔位節點開關2143。檔位機構214配合檔位節點開關2143以切換車輛的行車檔位。離合器操作桿2151用以供騎乘者操作離合器215的動作，以配合檔位機構214進行入檔行為(或稱檔位切換行為)。檔位機構214中，檔位節點開關2143與各檔位節點2142係同軸心扇形，且檔位節點開關2143為金屬片以扇形軸心進行樞轉，各檔位節點2142及空檔節點2141位於金屬片樞轉路徑上，同一時間檔位節點開關2143僅與一節點相接，以提供一檔位節點控制訊號，檔位節點控制訊號會由電子控制器20所接收，以得知檔位機構214所處的檔位，故檔位節點開關2143接於空檔節點2141時，電子控制器20係接收檔位機構214提供之一內容為空檔的檔位節點控制訊號。切換檔位前，騎乘者需操控離合器215連接的離合器操作桿2151，離合器操作桿2151受操作時，會觸發配置於離合器操作桿2151的一節點開關2152，以發出一操作桿節點控制訊號至電子控制器20，供電子控制器20得知騎乘者欲進行檔位切換作業。The electronic controller 20 is connected to the node switch 2152 of the above-described clutch operating lever 2151 and the gear position switch 2143 of the gear position mechanism 214. The gear mechanism 214 cooperates with the gear position switch 2143 to switch the driving position of the vehicle. The clutch operating lever 2151 is used for the rider to operate the clutch 215 to cooperate with the gear mechanism 214 for the inbound behavior (or the gear shifting behavior). In the gear mechanism 214, the gear position switch 2143 and the gear position node 2142 are coaxially fan-shaped, and the gear position switch 2143 is a metal piece pivoted by a fan-shaped axis, and each gear node 2142 and the neutral node 2141 are located. In the metal sheet pivoting path, the same time gear position node switch 2143 is only connected to a node to provide a gear position node control signal, and the gear position node control signal is received by the electronic controller 20 to know the gear position mechanism. When the gear position node switch 2143 is connected to the neutral node 2141, the electronic controller 20 receives the gear position control signal provided by the gear position mechanism 214. Before switching the gear position, the rider needs to operate the clutch operating lever 2151 connected to the clutch 215. When the clutch operating lever 2151 is operated, a node switch 2152 disposed on the clutch operating lever 2151 is triggered to send a lever node control signal to The electronic controller 20 is provided to the electronic controller 20 to learn that the rider wants to perform a gear shifting operation.
此時，引擎怠速熄火條件會更包括(1)檔位機構214處於空檔，也就是檔位節點開關2143切換連接至空檔節點2141時，會提供一內容為空檔的檔位節點控制訊號來供電子控制器20接收，微控制單元46即分析檔位節點控制訊號得知目前檔位機構214處於空檔檔位。(2)離合器於一時段內未受操作，如騎乘者放開離合器至少3秒，也就是3秒內，離合器操作桿2151未受騎乘者操控，電子控制器20未收到離合器操作桿2151的節點開關2152被觸發而發出的操作桿節點開關訊號。At this time, the engine idle-off condition may further include (1) the gear mechanism 214 is in neutral, that is, when the gear node switch 2143 is switched to the neutral node 2141, a gear node control signal with a content of neutral is provided. For the electronic controller 20 to receive, the micro control unit 46 analyzes the gear node control signal to know that the current gear mechanism 214 is in the neutral gear position. (2) The clutch is not operated for a period of time. If the rider releases the clutch for at least 3 seconds, that is, within 3 seconds, the clutch lever 2151 is not operated by the rider, and the electronic controller 20 does not receive the clutch lever. The node switch 2152 of 2151 is triggered to issue a lever node switching signal.
當車輛暫停期間，運轉資訊符合上述的引擎怠速熄火條件，微控制單元46會等待一預設時間(如3秒)後，才令引擎24停止、熄火。During the vehicle suspension period, the operation information conforms to the above-described engine idle-stop condition, and the micro-control unit 46 waits for a predetermined time (for example, 3 seconds) before the engine 24 is stopped and turned off.
請參閱圖5繪示本發明實施例之電子控制器20的第三種系統架構應用示意圖，請同時參閱圖2至圖4以利於了解。與前述實施例不同處在於，本例之系統配置有連接電子控制器20的一強制怠速熄火開關27。Please refer to FIG. 5 , which illustrates a third system architecture application diagram of the electronic controller 20 according to an embodiment of the present invention. Please refer to FIG. 2 to FIG. 4 to facilitate understanding. The difference from the foregoing embodiment is that the system of this example is provided with a forced idle extinguishing switch 27 connected to the electronic controller 20.
當強制怠速熄火開關27被啟用時，微控制單元46會從強制怠速熄火開關27取得一強制怠速熄火訊號。當微控制單元46判定車輛之運轉資訊符合上述的引擎怠速熄火條件時，不會等待一預設時間，而是立即停止點火單元22b與供油單元22a之至少其一的運作，以令引擎24熄火以進入一怠速熄火模式。在此說明，強制怠速熄火開關27為騎乘者方便按壓的按鍵、或施行開啟、關閉的切換開關，需配置於車輛的外部以供騎乘者操作，使得騎乘者得以隨時啟動或關閉強制怠速熄火開關27，完成手動控制引擎怠速熄火模式的需求。When the forced idle extinguishing switch 27 is enabled, the micro control unit 46 obtains a forced idle extinguishing signal from the forced idle extinguishing switch 27. When the micro control unit 46 determines that the operation information of the vehicle meets the above-described engine idle stop condition, it does not wait for a predetermined time, but immediately stops the operation of at least one of the ignition unit 22b and the oil supply unit 22a to make the engine 24 Turn off the flame to enter an idle stop mode. Here, the forced idle extinguishing switch 27 is a button that is conveniently pressed by the rider, or a switch that performs opening and closing, and needs to be disposed outside the vehicle for the rider to operate, so that the rider can be started or turned off at any time. The idle stop switch 27 completes the need to manually control the engine idle stop mode.
而另一種運作模式為，車輛的側支架機構28配置有一側支架節點開關281連接至電子控制器20，微控制單元46會透過與側支架節點開關281連接的側支架檢知電路以得知側支架機構28的位置。當側支架機構28位於下置位置時，側支架節點開關281係受觸發而發送一內容資訊為側支架節點開關281處於駐車狀態的側支架節點控制訊號。當微控制單元46透過側支架檢知電路取得此側支架節點控制訊號，並判定車輛之運轉資訊符合上述的引擎怠速熄火條件時，微控制單元46不會等待一預設時間，而是立即停止點火單元22b與供油單元22a之至少其一的運作，以令引擎24熄火以進入一怠速熄火模式。In another mode of operation, the side bracket mechanism 28 of the vehicle is configured with a side bracket node switch 281 connected to the electronic controller 20, and the micro control unit 46 transmits the side bracket detecting circuit connected to the side bracket node switch 281 to know the side. The position of the bracket mechanism 28. When the side bracket mechanism 28 is in the lower position, the side bracket node switch 281 is triggered to transmit a content information that the side bracket node switch 281 is in the parking state side bracket node control signal. When the micro control unit 46 obtains the side bracket node control signal through the side bracket detecting circuit, and determines that the running information of the vehicle meets the above-mentioned engine idle speed extinguishing condition, the micro control unit 46 does not wait for a preset time, but stops immediately. The operation of at least one of the ignition unit 22b and the oil supply unit 22a causes the engine 24 to be turned off to enter an idle stop mode.
在此說明，側支架節點開關281在側支架機構28處於下置位置時，呈現駐車狀態。當側支架節點開關281在側支架機構28處於非下置位置(如中置或上置位置)時，呈現非駐車狀態。以本實施例而言，當騎乘者將車輛暫時停止，並放下側支架機構形成駐車狀態時，側支架節點開關281即由開啟(on)轉至關閉(off)，微控制單元46會立即的強迫引擎熄火，達到駐車後即強制進入怠速熄火模式的需求。Here, the side bracket node switch 281 assumes a parking state when the side bracket mechanism 28 is in the down position. When the side stand node switch 281 is in a non-down position (such as a center or up position) when the side stand mechanism 28 is present, it assumes a non-parking state. In the present embodiment, when the rider temporarily stops the vehicle and lowers the side bracket mechanism to form the parking state, the side bracket node switch 281 is turned from on to off, and the micro control unit 46 immediately The forced engine is turned off, and the demand for forced entry into the idle stop mode is reached after parking.
不論採用圖2至圖5何種怠速控制系統，當引擎24處於怠速熄火的一預設時間(如20分鐘，但不以此為限，可由設計人員依需求設定)內，騎乘者欲令打檔式車輛前進時，係先操作離合器215連接的離合器操作桿2151，並配合檔位機構214以進行入檔行為。期間，節點開關2152會受觸發而發出節點開關訊號，電子控制器20會接收上述的離合器操作桿節點控制訊號，並分析其內容為開啟，以得知感測離合器215受操作。或者，騎乘者欲令自排檔式車輛前進時，僅需催動油門，微控制單元46即透過油門開度感測器212得知油門未處於原點預設值。Regardless of the idle speed control system of Figures 2 to 5, when the engine 24 is in a preset time (such as 20 minutes, but not limited to this, can be set by the designer according to the requirements), the rider wants to make When the shifting vehicle is moving forward, the clutch operating lever 2151 connected to the clutch 215 is operated first, and the gear position mechanism 214 is engaged to perform the shifting behavior. During this period, the node switch 2152 is triggered to issue a node switching signal, and the electronic controller 20 receives the above-mentioned clutch lever node control signal and analyzes the content thereof to be turned on to know that the sensing clutch 215 is operated. Alternatively, when the rider wants to advance the self-displacement vehicle, only the throttle is required to be actuated, and the micro-control unit 46, through the accelerator opening sensor 212, knows that the throttle is not at the origin preset value.
之後，電子控制器20係驅動供油單元22a，即油泵221與噴油嘴222進行引擎供油作業，再驅動點火單元22b，即點火線圈223及火星塞224對供油單元22a之供油進行點火作業，同時令啟動馬達23運轉，藉此啟動引擎24，以令引擎24從怠速熄火模式下恢復成啟動引擎狀態。騎乘者即能施行車輛起步動作而令車輛前進。Thereafter, the electronic controller 20 drives the oil supply unit 22a, that is, the oil pump 221 and the fuel injector 222 perform an engine oil supply operation, and then drives the ignition unit 22b, that is, the ignition coil 223 and the spark plug 224 supply oil to the oil supply unit 22a. The ignition operation, while the starter motor 23 is operated, thereby starting the engine 24 to return the engine 24 from the idle stop mode to the start engine state. The rider can perform the vehicle's starting action to advance the vehicle.
然而，當引擎24處於怠速熄火且超出上述的預設時間後，電子控制器20會認定車輛進入完全熄火狀態，以解除怠速熄火但不發動引擎24。騎乘者需將啟動開關25重新按壓，啟動開關25會提供的啟動訊號以供電子控制器20接收，電子控制器20會透過供油控制電路41驅動供油單元22a，以進行引擎供油作業；透過點火控制電路42驅動點火單元22b，以對供油單元22a之供油進行點火作業；透過馬達再啟動控制電路44觸發馬達繼電控制單元34，以使啟動馬達23開始運轉，藉此啟動引擎24，以令引擎24從怠速熄火模式下恢復成運作狀態。However, when the engine 24 is at idle speed and exceeds the predetermined time period described above, the electronic controller 20 determines that the vehicle has entered a fully flameout state to release the idle stop but does not activate the engine 24. The rider needs to press the start switch 25 again, and the start signal provided by the start switch 25 is received by the electronic controller 20, and the electronic controller 20 drives the oil supply unit 22a through the oil supply control circuit 41 to perform the engine oil supply operation. The ignition unit 22b is driven by the ignition control circuit 42 to perform an ignition operation on the oil supply unit 22a; the motor relay control unit 34 is triggered by the motor restart control circuit 44 to start the operation of the starter motor 23, thereby starting The engine 24 is configured to return the engine 24 from an idle stop mode to an operational state.
然而，圖2至圖5之各實施例可單獨個別施作或共同施作，不以此等實施例之方式為限。其次，上述電壓下限值、車速之下限值、原點預設值、怠速轉速、離合器未受操作時間與電子控制器20等待之預設時間等，並不以上述為限，乃因應設計人員之需求而得作相似變化。However, the embodiments of FIG. 2 to FIG. 5 may be individually or collectively applied, and are not limited to the manner of the embodiments. Secondly, the above-mentioned voltage lower limit value, the vehicle speed lower limit value, the origin preset value, the idle speed, the clutch unoperated time, and the preset time waiting for the electronic controller 20 are not limited to the above, and are designed according to the above. Similar changes have been made to the needs of personnel.
請參閱圖6A繪示之本發明實施例之車輛引擎怠速控制方法第一種引擎怠速熄火流程示意圖及圖6B繪示本發明實施例之車輛狀態檢知流程示意圖，此方法乃由一電子控制器20判斷打檔式車輛之運轉資訊，控制引擎怠速熄火，及重新啟動引擎。請同時參閱圖2與圖3以利於了解，控制方法說明如下：判斷怠速功能切換開關35是否開啟(S110)。如圖3，開關偵測單元45連接至怠速功能切換開關35，乃用以偵測怠速功能切換開關35的開啟與關閉，以產生相關的開關狀態訊號至微控制單元46，微控制單元46會解析開關狀態訊號得知怠速功能切換開關35為開啟或關閉，以決定是否啟用怠速偵測模式。FIG. 6A is a schematic diagram of a first engine idle stop process of the vehicle engine idle speed control method according to an embodiment of the present invention, and FIG. 6B is a schematic diagram of a vehicle state detection process according to an embodiment of the present invention. The method is performed by an electronic controller. 20 Judging the operation information of the shifting type vehicle, controlling the engine to ignite the flame, and restarting the engine. Please refer to FIG. 2 and FIG. 3 at the same time to understand that the control method is as follows: It is determined whether the idle function switch 35 is turned on (S110). As shown in FIG. 3, the switch detecting unit 45 is connected to the idle function switching switch 35 for detecting the opening and closing of the idle function switching switch 35 to generate an associated switching state signal to the micro control unit 46, and the micro control unit 46 The switch state signal is analyzed to know that the idle function switch 35 is turned on or off to determine whether the idle detection mode is enabled.
當微控制單元46判斷怠速功能切換開關35未開啟時，開關偵測單元45會持續偵測怠速功能切換開關35的狀態是否切換，微控制單元46則是正常執行其它的裝置控制、資料收發行為。When the micro control unit 46 determines that the idle function switching switch 35 is not turned on, the switch detecting unit 45 continuously detects whether the state of the idle function switching switch 35 is switched, and the micro control unit 46 performs other device control and data transmission and reception behavior normally. .
當微控制單元46判斷怠速功能切換開關35開啟時，微控制單元46即透過各感知電路47以檢知車輛之各運作狀態(步驟S120)。如圖6B，步驟S120的檢知步驟中，並未有任何先後順序，在此僅用以輔助說明。如圖6B，步驟S120包括多個檢知步驟，包括：一車速檢知手段(步驟S211)，藉由車速感測器211感測車輛之車速。一油門開度檢知手段(步驟S212)，藉由油門開度感測器212感測車輛之油門的開啟程度，即油門開度。一引擎轉速檢知手段(步驟S213)，藉由引擎轉速感測器213感測引擎目前的轉速。When the micro control unit 46 determines that the idle function switching switch 35 is turned on, the micro control unit 46 transmits the respective sensing circuits 47 to detect the respective operating states of the vehicle (step S120). As shown in FIG. 6B, the step of detecting in step S120 does not have any order, and is only used to assist the description. As shown in FIG. 6B, step S120 includes a plurality of detecting steps including: a vehicle speed detecting means (step S211), wherein the vehicle speed is sensed by the vehicle speed sensor 211. An accelerator opening detecting means (step S212) senses the degree of opening of the throttle of the vehicle, that is, the accelerator opening degree, by the accelerator opening degree sensor 212. An engine speed detecting means (step S213), the engine speed sensor 213 senses the current engine speed.
而對於打檔式車輛，步驟S120的檢知步驟更包括一檔位檢知手段(步驟S214)，如前述，檔位機構214配合檔位節點開關2143以切換車輛的行車檔位，電子控制器20係連接檔位節點開關2143，以檢知所取得的檔位節點控制訊號之內容是否為空檔。檔位機構214內置有一個以上的檔位節點2142，其一者為空檔節點2141，檔位節點開關2143與各檔位節點2142係同軸心扇形，且檔位節點開關2143為金屬片以扇形軸心進行樞轉，各檔位節點2142及空檔節點2141位於金屬片樞轉路徑上，同一時間檔位節點開關2143僅與一節點相接，以提供一檔位節點控制訊號，檔位節點控制訊號會由電子控制器20所接收，以得知檔位機構214所處的檔位，故檔位節點開關2143接於空檔節點2141時，電子控制器20係接收檔位節點開關2143提供之一內容為空檔的檔位節點控制訊號。一離合器檢知手段(步驟S215)，離合器215的離合器操作桿2151用以供騎乘者操作，以配合檔位機構214進行入檔行為(或稱檔位切換行為)。切換檔位前，騎乘者需操控離合器215連接的離合器操作桿2151，離合器操作桿2151受操作時，會觸發配置於離合器操作桿2151的一節點開關2152，以發出一操作桿節點控制訊號至電子控制器20，供電子控制器20得知騎乘者欲進行檔位切換作業。For the shift type vehicle, the detecting step of step S120 further includes a gear position detecting means (step S214). As described above, the gear position mechanism 214 cooperates with the gear position node switch 2143 to switch the driving position of the vehicle, the electronic controller. The 20 series is connected to the gear position node switch 2143 to detect whether the content of the obtained gear position node control signal is neutral. The gear mechanism 214 has one or more gear nodes 2142 built therein, one of which is a neutral node 2141, the gear node switch 2143 and each gear node 2142 are coaxially fan-shaped, and the gear node switch 2143 is a metal plate in a fan shape. The axis pivots, the gear node 2142 and the neutral node 2141 are located on the metal sheet pivoting path, and the same time gear node switch 2143 is connected to only one node to provide a gear node control signal, the gear node The control signal is received by the electronic controller 20 to know the gear position in which the gear mechanism 214 is located. When the gear position switch 2143 is connected to the neutral node 2141, the electronic controller 20 receives the gear position switch 2143. One of the contents is a neutral gear node control signal. A clutch detecting means (step S215), the clutch operating lever 2151 of the clutch 215 is used for the rider to operate in conjunction with the gear mechanism 214 for the inbound behavior (or the gear shifting behavior). Before switching the gear position, the rider needs to operate the clutch operating lever 2151 connected to the clutch 215. When the clutch operating lever 2151 is operated, a node switch 2152 disposed on the clutch operating lever 2151 is triggered to send a lever node control signal to The electronic controller 20 is provided to the electronic controller 20 to learn that the rider wants to perform a gear shifting operation.
電子控制器20用以接收上述各感測器提供的車輛運轉資訊，以判定上述的運轉資訊是否符合一引擎怠速熄火條件(步驟S130)。引擎怠速熄火條件例如：(1)電子控制器20判定車速感測器211所感測的車速(或是輪速)為零，即車輛處於靜止狀態。(2)油門開度需達到一原點預設值。(3)引擎24為怠速狀態，即引擎轉速需達到一怠速轉速以下。而應用於打檔式車輛時，引擎怠速熄火條件更包括：(4)檔位機構214處於空檔，也就是檔位節點開關2143切換連接至空檔節點2141時，會提供一內容為空檔的檔位節點控制訊號來供電子控制器20接收，電子控制器20即分析檔位節點控制訊號得知目前檔位機構214處於空檔檔位。(5)離合器215於一時間內未受操作，如3秒內，離合器操作桿2151未受騎乘者操控，電子控制器20未收到離合器操作桿2151的節點開關2152被觸發而發出的操作桿節點開關訊號。The electronic controller 20 is configured to receive the vehicle operation information provided by each of the sensors to determine whether the operation information meets an engine idle stop condition (step S130). The engine idle speed extinguishing condition is, for example: (1) The electronic controller 20 determines that the vehicle speed (or the wheel speed) sensed by the vehicle speed sensor 211 is zero, that is, the vehicle is in a stationary state. (2) The throttle opening needs to reach an original preset value. (3) The engine 24 is in an idle state, that is, the engine speed needs to be below an idle speed. When applied to a shifting type vehicle, the engine idle speeding condition further includes: (4) the gear position mechanism 214 is in neutral, that is, when the gear position node switch 2143 is switched to the neutral node 2141, a content is provided as a neutral. The gear node control signal is received by the electronic controller 20, and the electronic controller 20 analyzes the gear node control signal to know that the current gear mechanism 214 is in the neutral gear position. (5) The clutch 215 is not operated for a period of time, for example, within 3 seconds, the clutch operating lever 2151 is not manipulated by the rider, and the electronic controller 20 does not receive the operation of the node switch 2152 of the clutch operating lever 2151 being triggered. Rod node switching signal.
當電子控制器20判定運轉資訊符合上述的引擎怠速熄火條件時，係判定運轉資訊是否經過一預設時間仍符合引擎怠速熄火條件(步驟S131)。When the electronic controller 20 determines that the operation information meets the above-described engine idle-stop condition, it is determined whether the operation information has passed the engine idle-off condition for a predetermined period of time (step S131).
當電子控制器20判定運轉資訊不符合上述的引擎怠速熄火條件，或是預設時間內，運轉資訊有變動而違反上述的引擎怠速熄火條件，即重新施行步驟S120。When the electronic controller 20 determines that the operation information does not meet the above-described engine idle-off condition, or the operation information changes within a preset time and violates the above-described engine idle-stop condition, step S120 is re-executed.
反之，當電子控制器20判定已經過上述的預設時間(如3秒)，電子控制器20會施行一引擎熄火控制手段，即停止驅動引擎24的供油單元22a或點火單元22b之至少其一，以令引擎24熄火，以自動進入一怠速熄火模式(步驟S140)。On the contrary, when the electronic controller 20 determines that the preset time (for example, 3 seconds) has elapsed, the electronic controller 20 performs an engine flameout control means, that is, stops at least the oil supply unit 22a or the ignition unit 22b of the drive engine 24. First, the engine 24 is turned off to automatically enter an idle stop mode (step S140).
如圖3，電子控制器20包括一剎車燈控制電路32，當微控制單元46判斷啟用怠速熄火模式時，微控制單元46會利用剎車燈控制電路32啟動剎車燈33，令其持續發光(步驟S150)。As shown in FIG. 3, the electronic controller 20 includes a brake light control circuit 32. When the micro control unit 46 determines that the idle stop mode is enabled, the micro control unit 46 activates the brake light 33 by the brake light control circuit 32 to continue to emit light (steps). S150).

Please refer to FIG. 5 to understand that the difference from the first engine idle speed extinguishing flow diagram is in step S132. Decision step.
當電子控制器20判定運轉資訊符合上述的引擎怠速熄火條件時，係判定強制怠速熄火開關27是否為開啟(步驟S132)。當電子控制器20判定強制怠速熄火開關27被啟用時，電子控制器20係立即施行一引擎熄火控制手段，亦是指不等待一預設時間，而立即停止驅動引擎24的供油單元22a或點火單元22b之至少其一，以令引擎24熄火，進入一怠速熄火模式(步驟S140)。When the electronic controller 20 determines that the operation information meets the above-described engine idle-stop condition, it is determined whether or not the forced idle-extinguishing switch 27 is ON (step S132). When the electronic controller 20 determines that the forced idle extinguishing switch 27 is enabled, the electronic controller 20 immediately performs an engine flameout control means, that is, immediately stops the fuel supply unit 22a of the drive engine 24 without waiting for a predetermined time. At least one of the ignition units 22b causes the engine 24 to be turned off to enter an idle stop mode (step S140).
請參閱圖6D繪示之本發明實施例之車輛排檔引擎怠速控制方法第三種引擎怠速熄火流程示意圖，請同時參閱圖5以利於了解，與前數種引擎怠速熄火流程示意圖不同處在於步驟S133之判定步驟。Please refer to FIG. 6D, which is a schematic diagram of the third engine idle stop process of the vehicle gear engine idle speed control method according to the embodiment of the present invention. Please refer to FIG. 5 to facilitate understanding, and the difference from the previous engine idle speed flameout process diagram is in step S133. The decision step.
當電子控制器20判定運轉資訊符合上述的引擎怠速熄火條件時，係判定側支架節點開關281是否為駐車狀態(步驟S133)。上述的側支架機構28包括一側支架節點開關281，當側支架機構28位於下置位置時，側支架節點開關281係受觸發而發送一內容資訊為側支架節點開關281處於駐車狀態的側支架節點控制訊號。當電子控制器20取得側支架節點控制訊號以判定側支架節點開關281處於駐車狀態，即側支架機構28位於下置位置而非上置、中置等其它位置時，電子控制器20不會等待一預設時間，而是立即停止驅動引擎24之供油單元22a與點火單元22b之至少其一者，以使得引擎24熄火而進入一怠速熄火模式(步驟S140)。When the electronic controller 20 determines that the operation information meets the above-described engine idle-stop condition, it is determined whether or not the side-bracket node switch 281 is in the parking state (step S133). The side bracket mechanism 28 includes a side bracket node switch 281. When the side bracket mechanism 28 is in the lower position, the side bracket node switch 281 is triggered to send a content information to the side bracket of the side bracket node switch 281 in the parking state. Node control signal. When the electronic controller 20 obtains the side bracket node control signal to determine that the side bracket node switch 281 is in the parking state, that is, the side bracket mechanism 28 is in the lower position instead of the upper, middle, and the like, the electronic controller 20 does not wait. At a predetermined time, at least one of the oil supply unit 22a and the ignition unit 22b of the drive engine 24 is immediately stopped to cause the engine 24 to be turned off to enter an idle stop mode (step S140).
然而，圖6A至圖6D亦能單一施行或共同施行，如圖6E繪示本發明實施例圖6A、圖6C與圖6D共同施行之流程示意圖，當步驟S130完成後，係以步驟S132、步驟S133與步驟S131的先後判定順序作怠速熄火模式的進入判定，以確實啟用引擎24的怠速熄火模式。However, FIG. 6A to FIG. 6D can also be performed singly or jointly. FIG. 6E is a schematic diagram of the flow of FIG. 6A, FIG. 6C and FIG. 6D according to an embodiment of the present invention. When step S130 is completed, step S132 is followed. The order of determination of S133 and step S131 is determined as the entry of the idle stop mode to surely enable the idle stop mode of the engine 24.
請參閱圖6F繪示之本發明實施例車輛引擎怠速控制方法第一種引擎啟動引擎流程示意圖。其承接圖6A、圖6C與圖6D任一種單一技術施行或如圖6E之多數技術共同施行的怠速熄火作業。請同時參閱圖3以利於了解。Please refer to FIG. 6F , which is a schematic diagram of a first engine startup engine flow of the vehicle engine idle speed control method according to an embodiment of the present invention. It undertakes an idle speed quenching operation performed by either a single technique of FIG. 6A, FIG. 6C and FIG. 6D or jointly performed by most of the techniques of FIG. 6E. Please also refer to Figure 3 for your understanding.
於步驟S140或步驟S150後，電子控制器20會判斷是否取得一起步動作資訊(步驟S161)。當電子控制器20取得起步動作資訊時，係施行一引擎再啟動控制手段。在此說明，所謂起步動作資訊有兩種，一為使用者催動油門時，微控制單元46透過油門開度感測器212得知油門不處於原點預設值。另一為打檔式車輛中，當使用者操作離合器時，離合器的操作桿節點開關提供的操作桿節點控制訊號，微控制單元46即透過操作桿節點控制訊號得知離合器正***作。After step S140 or step S150, the electronic controller 20 determines whether or not the step-by-step motion information is acquired (step S161). When the electronic controller 20 obtains the start motion information, an engine restart control means is implemented. Herein, there are two kinds of start motion information. When the user pushes the throttle, the micro control unit 46 learns through the throttle opening sensor 212 that the throttle is not at the origin preset value. In another type of shifting type vehicle, when the user operates the clutch, the operating lever node control signal provided by the operating lever node switch of the clutch, the micro control unit 46 knows that the clutch is being operated through the operating lever node control signal.
之後，微控制單元46會驅動供油單元22a，即油泵221與噴油嘴222進行引擎供油作業，再驅動點火單元22b，即點火線圈223及火星塞224對供油單元22a之供油進行點火作業，同時令啟動馬達23運轉，藉此啟動引擎24(步驟S170)，以令引擎24從怠速熄火模式下恢復成啟動狀態，同時解除剎車燈控制電路32對剎車燈33的控制，剎車燈33回復正常工作狀態。之後，騎乘者即能進行車輛起步動作而令車輛前進。Thereafter, the micro control unit 46 drives the oil supply unit 22a, that is, the oil pump 221 and the fuel injection nozzle 222 perform an engine oil supply operation, and then drives the ignition unit 22b, that is, the ignition coil 223 and the spark plug 224 supply oil to the oil supply unit 22a. The ignition operation simultaneously causes the starter motor 23 to operate, thereby starting the engine 24 (step S170) to return the engine 24 from the idle stop mode to the activated state, and simultaneously releasing the brake light control circuit 32 to control the brake light 33, the brake light 33 returned to normal working condition. After that, the rider can start the vehicle and move the vehicle forward.
請參閱圖6G繪示之本發明實施例車輛排檔引擎怠速控制方法第二種引擎啟動引擎流程示意圖。其承接圖6A、圖6C與圖6D任一種單一施行或共同施行的怠速熄火作業。請同時參閱圖5以利於了解。Please refer to FIG. 6G , which is a schematic diagram of a second engine startup engine flow of the vehicle gear engine idle speed control method according to an embodiment of the present invention. It undertakes any of the singular flameout operations of FIG. 6A, FIG. 6C and FIG. 6D which are performed alone or jointly. Please also refer to Figure 5 for easy understanding.
於步驟S140或步驟S150後，電子控制器20會判斷啟動開關25是否受操作(步驟S162)。如騎乘者將怠速熄火模式誤認為車輛的完全熄火模式(引擎24及各相關元件停止運作狀態)，亦能操作一啟動開關25進行車輛發動作業。此時，電子控制器20會將啟動開關25提供的啟動訊號視為喚醒引擎24的控制訊號，以驅動供油單元22a與點火單元22b，同時啟動馬達23運轉，藉此啟動引擎24，以令引擎24從怠速熄火模式下恢復成啟動狀態(步驟S170)。After step S140 or step S150, the electronic controller 20 determines whether the start switch 25 is operated (step S162). If the rider mistakes the idle stop mode for the complete flameout mode of the vehicle (the engine 24 and the related components are stopped), a start switch 25 can also be operated to perform the vehicle starting operation. At this time, the electronic controller 20 regards the start signal provided by the start switch 25 as the control signal of the wake-up engine 24 to drive the oil supply unit 22a and the ignition unit 22b, and simultaneously activates the motor 23 to operate, thereby starting the engine 24 to The engine 24 is restored to the activated state from the idle-off mode (step S170).
然後，圖6F或圖6G之流程施行後，皆會返回前述的步驟S110，以施行車輛的運轉資訊檢知作業。而且圖6F與圖6G亦能結合共同施行以如圖6H所繪示。Then, after the execution of the flow of FIG. 6F or FIG. 6G, the process returns to the above-described step S110 to perform the operation information detection operation of the vehicle. Moreover, FIG. 6F and FIG. 6G can also be combined to perform as shown in FIG. 6H.
