Description

本発明は、エンジンの運転状態に応じたスロットル弁の開度調整を、電動モータ等のスロットルアクチュエータで行う電子制御式スロットル弁の制御装置に関する。   The present invention relates to a control device for an electronically controlled throttle valve that adjusts the opening of a throttle valve in accordance with the operating state of an engine with a throttle actuator such as an electric motor.

従来、スロットル付きエンジンではスロットル弁の開度で混合気量を調整しており、減速時にスロットル弁は閉じられる。
ところで、昨今、スロットル弁とアクセルペダルをスロットルワイヤを介して機械的に連結した従来構造に代え、特許文献１に開示されるようにスロットルアクチュエータでスロットル弁の開度制御を行う電子制御式スロットル弁の制御装置が知られており、この制御装置によれば、予めマップ等に非線形特性に応じたデータを格納しておき、アクセル操作量をパラメータとしてこのマップを参照することで、アクセル操作量とスロットル弁開度変化との関係をエンジンの運転状態毎に最適な非線形率に制御することが可能となって、良好なドライバビリティを得ることが可能となる。
特開２０００−７３７８９号公報 Conventionally, in an engine with a throttle, the amount of air-fuel mixture is adjusted by the opening of the throttle valve, and the throttle valve is closed during deceleration.

しかし、特許文献１に開示された制御装置は、ギヤ段（低速段・高速段）と車速（低車速・高車速）により運転状態を分別してアクセル操作量に対するスロットル操作量特性を設定しているが、実際にこの特性が必要になるのは低速ギヤ段の使用時であり、余裕駆動力が少ない高速ギヤ段ではこの特性による運転性への影響が少ないため、斯様に特性を格別に設定する必要はない。   However, the control device disclosed in Patent Literature 1 sets the throttle operation amount characteristic with respect to the accelerator operation amount by classifying the driving state according to the gear stage (low speed stage / high speed stage) and the vehicle speed (low vehicle speed / high vehicle speed). However, this characteristic is actually required when using a low-speed gear stage, and the high-speed gear stage with less marginal driving force has little effect on drivability. do not have to.

また、上述の如くギヤ段と車速によって運転状態を分別しているため、ギヤ段を判別するためのセンサや信号入力用インターフェースが必要となってコストがかかってしまう不具合も指摘されていた。
本発明は斯かる実情に鑑み案出されたもので、従来に比しより少ないコストで運転性に優れた電子制御式スロットル弁の制御装置を提供することを目的とする。 In addition, as described above, since the driving state is classified according to the gear stage and the vehicle speed, a problem has been pointed out that a sensor and a signal input interface are required for determining the gear stage, which increases costs.

Detection means, accelerator depression amount detection means for detecting the depression amount of the accelerator, throttle valve opening detection means for detecting the opening amount of the throttle valve, and storage means, stored in the storage means, from the engine speed and the accelerator opening The operation state is classified into a plurality of operation modes, a map in which a target throttle operation amount corresponding to the accelerator depression amount is set for each operation mode, and a rotation speed detection means, an accelerator depression amount detection means, and a throttle opening degree detection means A control unit for inputting each detection signal, and the control unit receives the detection signal from each detection means. To identify the operating mode of the engine, based on the map of the identified operating mode, characterized in that to operate the throttle valve through the throttle actuator.

Have

以下、本発明の実施形態を図面に基づいて詳細に説明する。
図１は請求項１及び請求項２の一実施形態に係る電子制御式スロットル弁の制御装置の概略構成図を示し、図中、１はエンジンの吸気通路中に装着されたスロットル弁で、当該スロットル弁１は、電動モータ等のスロットルアクチュエータ３で開度制御される電子制御式スロットル弁である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic configuration diagram of a control device for an electronically controlled throttle valve according to an embodiment of claims 1 and 2, in which 1 is a throttle valve mounted in an intake passage of an engine, The throttle valve 1 is an electronically controlled throttle valve whose opening degree is controlled by a throttle actuator 3 such as an electric motor.

そして、本実施形態は、エンジンの運転状態に適したスロットル弁１の開度制御を可能とするため、図２の如くエンジン回転数とアクセル開度を基にエンジンの運転状態を領域Ａ〜Ｅの複数の運転モードに分別している。
即ち、図２中、領域Ａ「アイドル走行または低速走行」は、図１のアクセルペダル５を踏まないで低いエンジン回転数で走行している運転モードであり、領域Ｂ「減速走行または降坂走行」は、例えばアクセルペダル５を離して減速しているときや降坂走行時の如く、エンジン回転数は高いがアクセルペダル５の踏込量が少ない運転モードである。 In this embodiment, in order to enable the opening degree control of the throttle valve 1 suitable for the operating state of the engine, the operating state of the engine is represented in the areas A to E based on the engine speed and the accelerator opening as shown in FIG. There are several operation modes.
That is, in FIG. 2, region A “idle traveling or low-speed traveling” is an operation mode in which the vehicle is traveling at a low engine speed without stepping on the accelerator pedal 5 in FIG. "Is an operation mode in which the engine pedal is high but the amount of depression of the accelerator pedal 5 is small, for example, when the accelerator pedal 5 is decelerated and the vehicle is traveling downhill.

また、領域Ｃ「通常加速または通常走行」は、通常に加速したり一定速度で走行している場合のように、アクセルペダル５を踏み込み過ぎずエンジン回転数も通常の場合の通常走行域運転モードであり、領域Ｄ「フル加速または登坂走行」は、エンジン回転数が最高回転域まで達していないが、アクセルペダル５をかなり踏み込んでいる急加速域運転モードである。   The region C “normal acceleration or normal travel” is a normal travel region operation mode in which the accelerator pedal 5 is not depressed too much and the engine speed is normal, as in normal acceleration or traveling at a constant speed. Region D “full acceleration or running uphill” is a rapid acceleration region operation mode in which the engine speed does not reach the maximum rotational region but the accelerator pedal 5 is depressed considerably.

そして、領域Ｅ「最高速走行または登坂走行」は、エンジン回転数がレッドゾーン域近傍まで達している最高回転域運転モードで、このように本実施形態は、エンジンの運転状態に適したスロットル弁１の開度制御を行うため、エンジン回転数とアクセル開度を基にエンジンの運転状態を領域Ａ〜Ｅの運転モードに分別している。
尚、図２中、ACfhはフル加速（領域Ｄ）判定アクセル開度、ACidは低アクセル（領域Ａ，Ｂ）判定アクセル開度、そして、Nhlは最高回転域（領域Ｅ）判定エンジン回転数で、これらは運転状態を領域Ａ〜Ｅの各運転モードに分別するための基準値で、図１に示すコントロールユニット７内の記憶手段に設定，記憶されている。 The region E “highest speed traveling or uphill traveling” is a maximum rotational speed operation mode in which the engine speed reaches the vicinity of the red zone. Thus, the present embodiment is a throttle valve suitable for the engine operating state. In order to perform the opening degree control of 1, the engine operating state is classified into the operation modes of the regions A to E based on the engine speed and the accelerator opening degree.
In FIG. 2, ACfh is the full acceleration (region D) determination accelerator opening, ACid is the low accelerator (region A, B) determination accelerator opening, and Nhl is the maximum engine speed (region E) determination engine speed. These are reference values for classifying the operation state into the respective operation modes in the areas A to E, and are set and stored in the storage means in the control unit 7 shown in FIG.

そして、本実施形態は、領域Ａ〜Ｅの各運転モードに適したスロットル操作量の制御を図るため、各運転モード毎に、アクセル踏込量に応じた目標スロットル開度（目標スロットル操作量）を設定したマップをコントロールユニット７の記憶手段に記憶させている。
図３は「アクセル踏込量と目標スロットル開度特性」を示すマップで、細線で示すように領域Ａ〜Ｃ，Ｅの運転モードのマップは、運転者の意図に沿うようなスロットル操作を可能とするため、スロットル操作量がアクセル踏込量と同一な直線状のマップに設定されている。 In this embodiment, in order to control the throttle operation amount suitable for each operation mode in the areas A to E, the target throttle opening (target throttle operation amount) corresponding to the accelerator depression amount is set for each operation mode. The set map is stored in the storage means of the control unit 7.
FIG. 3 is a map showing “accelerator depression amount and target throttle opening characteristic”. As shown by thin lines, the map of the operation modes in the areas A to C and E enables the throttle operation in accordance with the driver's intention. Therefore, the throttle operation amount is set to the same linear map as the accelerator depression amount.

そして、領域Ｄでは、出来るだけ速くパワフルな加速が引き出せると共に、その反面、ショックやギクシャク感が現れないようなスロットル操作を可能とするため、図３の太線で示すように領域Ａ〜Ｃの運転モードの直線状のマップに比し、アクセル踏込量に対してスロットル操作量（スロットル開度）を大きくした円弧状のマップとされている。
一方、領域Ｅは最高回転域の運転モードであるため、エンジンの損傷を防ぐために回転上昇し過ぎないようにスロットル操作の抑制が必要である。 In the region D, powerful acceleration can be drawn out as quickly as possible, and on the other hand, in order to enable a throttle operation that does not cause a shock or jerky feeling, the operation in the regions A to C as shown by the thick lines in FIG. Compared with the linear map of the mode, the map is an arc-shaped map in which the throttle operation amount (throttle opening) is larger than the accelerator depression amount.
On the other hand, since the region E is an operation mode in the maximum rotation region, it is necessary to suppress the throttle operation so as not to increase the rotation excessively in order to prevent engine damage.

そこで、本実施形態は、上述したように図３の直線状のマップでスロットル開度制御を行うが、図４に示すようにエンジン回転数が２０００rpmを超える中高回転域から、目標スロットル開度の上限値としての過回転防止マップが記憶手段に設定，記憶されており、コントロールユニット７はエンジン回転数に対するスロットル開度がこのマップ以上に上がらないようにスロットルアクチュエータ３に指令を送出して、スロットル弁１の開度を制御するようになっている。そして、エンジン回転数が既述した最高回転域判定エンジン回転数Nhlを超えて領域Ｅに移行すると、コントロールユニット７は斯かるマップを基にスロットル開度を制御するようになっている。   Therefore, in the present embodiment, the throttle opening degree control is performed using the linear map of FIG. 3 as described above. However, as shown in FIG. An overspeed prevention map as an upper limit value is set and stored in the storage means, and the control unit 7 sends a command to the throttle actuator 3 so that the throttle opening relative to the engine speed does not exceed this map, and the throttle The opening degree of the valve 1 is controlled. When the engine speed exceeds the maximum engine speed determination engine speed Nhl described above and shifts to the area E, the control unit 7 controls the throttle opening based on such a map.

そして、図３及び図４のマップに基づきコントロールユニット７がスロットル開度を制御するため、図１に示すようにスロットル弁１にスロットル開度センサ９が装着され、その検出信号がコントロールユニット７に入力されている。
一方、エンジン回転数を検出するため、エンジンにクランク角センサ１１が装着されると共に、アクセルペダル５の踏込量を検出するため、当該アクセルペダル５にアクセルペダルセンサ１３が装着されており、両センサ１１，１３の検出信号がコントロールユニット７に入力されている。そして、コントロールユニット７は、既述したマップを基に、以下に記述する図５のフローチャートに基づいてスロットル開度を制御するようになっている。 Since the control unit 7 controls the throttle opening based on the maps of FIGS. 3 and 4, a throttle opening sensor 9 is mounted on the throttle valve 1 as shown in FIG. Have been entered.
On the other hand, a crank angle sensor 11 is mounted on the engine to detect the engine speed, and an accelerator pedal sensor 13 is mounted on the accelerator pedal 5 to detect the amount of depression of the accelerator pedal 5. Detection signals 11 and 13 are input to the control unit 7. The control unit 7 controls the throttle opening based on the above-described map based on the flowchart of FIG. 5 described below.

本実施形態に係るスロットル弁１の制御装置１５はこのように構成されているから、車両の走行に伴い、コントロールユニット７はステップＳ１に於て、スロットル開度センサ９，クランク角センサ１１，アクセルペダルセンサ１３からの検出信号を基に、現在のエンジン回転数Ｎとアクセル踏込量ＡＣとスロットル開度θとを夫々検出する。
そして、ステップＳ２で、先ずエンジン回転数Ｎ≧最高回転域判定エンジン回転数Nhl であるか否かを判断し、このステップＳ２でＮ≧Nhl であると判定すると、コントロールユニット７はステップＳ３に進んで、次にアクセル踏込量ＡＣ≦フル加速判定アクセル開度ACfhであるか否かを判断する。 Since the control device 15 for the throttle valve 1 according to the present embodiment is configured in this way, the control unit 7 controls the throttle opening sensor 9, the crank angle sensor 11, the accelerator in step S1 as the vehicle travels. Based on the detection signal from the pedal sensor 13, the current engine speed N, accelerator depression amount AC, and throttle opening θ are detected.
In step S2, it is first determined whether or not the engine rotational speed N ≧ maximum rotational speed range determination engine rotational speed Nhl. If it is determined in step S2 that N ≧ Nhl, the control unit 7 proceeds to step S3. Then, it is determined whether or not the accelerator depression amount AC ≦ the full acceleration determination accelerator opening ACfh.

而して、ステップＳ３でＡＣ≦ACfhと判定されると、コントロールユニット７は、エンジンの運転状態が領域Ｃの通常走行域運転モードであると識別して、ステップＳ４でアクセル踏込量ＡＣに応じた目標スロットル開度θobj を図３の直線状のマップから算出し、次いで、ステップＳ５に於て、現在スロットル開度θと目標スロットル開度θobj からスロットル変化量を算出し、この算出したスロットル変化量に応じスロットルアクチュエータ３を駆動させて、スロットル弁１の開度制御を行うこととなる（ステップＳ６）。   Thus, when it is determined in step S3 that AC ≦ ACfh, the control unit 7 identifies that the engine operating state is the normal traveling region operation mode of the region C, and responds to the accelerator depression amount AC in step S4. The target throttle opening θobj is calculated from the linear map of FIG. 3, and then in step S5, the throttle change amount is calculated from the current throttle opening θ and the target throttle opening θobj, and the calculated throttle change The throttle actuator 3 is driven according to the amount to control the opening degree of the throttle valve 1 (step S6).

また、ステップＳ３でＡＣ≧ACfhと判定すると、コントロールユニット７はエンジンの運転状態が領域Ｄの急加速域運転モードであると識別して、ステップＳ７でアクセル踏込量ＡＣに応じた目標スロットル開度θobj を図３の円弧状のマップから算出した後、同様にステップＳ５に於て、現在スロットル開度θと目標スロットル開度θobj からスロットル変化量を算出し、この算出したスロットル変化量に応じスロットルアクチュエータ３を駆動させてスロットル弁１の開度制御を行う（ステップＳ６）。   If it is determined in step S3 that AC ≧ ACfh, the control unit 7 recognizes that the engine operating state is the rapid acceleration region operation mode in the region D, and in step S7, the target throttle opening corresponding to the accelerator depression amount AC. After calculating θobj from the arc-shaped map of FIG. 3, similarly, in step S5, a throttle change amount is calculated from the current throttle opening θ and the target throttle opening θobj, and the throttle according to the calculated throttle change amount is calculated. The opening degree of the throttle valve 1 is controlled by driving the actuator 3 (step S6).

而して、この急加速域運転モードでは、図３に示すように円弧状のマップが設定されているため、僅かなアクセルペダル５の操作でパワフルな加速が得られることとなる。
一方、ステップＳ２でＮ≦Nhl であると判定すると、コントロールユニット７はエンジンの運転状態が領域Ｅの最高回転域運転モードにあると判定して、ステップＳ８に於て、エンジン回転数Ｎに応じた目標スロットル開度θobj を図３のマップから算出すると共に、図４の過回転防止マップからエンジン回転数Ｎに応じた上限値たる目標スロットル開度θobj を求めて、低い値を目標スロットル開度θobj とする。 Thus, in this rapid acceleration region operation mode, since an arc-shaped map is set as shown in FIG. 3, powerful acceleration can be obtained by a slight operation of the accelerator pedal 5.
On the other hand, if it is determined in step S2 that N ≦ Nhl, the control unit 7 determines that the engine operating state is in the maximum rotation range operation mode of the region E, and according to the engine speed N in step S8. 3 is calculated from the map of FIG. 3, and the target throttle opening θobj which is the upper limit value corresponding to the engine speed N is obtained from the overspeed prevention map of FIG. Let it be θobj.

そして、同様にステップＳ５で、現在スロットル開度θと目標スロットル開度θobj からスロットル変化量を算出し、この算出したスロットル変化量に応じスロットルアクチュエータ３を駆動させてスロットル弁１の開度制御を行うことで、エンジンの過回転を防止してエンジンの損傷を防ぐこととなる（ステップＳ６）。
このように本実施形態は、図２の如くエンジン回転数とアクセル開度を基にエンジンの運転状態を領域Ａ〜Ｅの複数の運転モードに分別し、各運転モードに於けるマップを設定してエンジンの運転状態に適したスロットル弁１の開度制御を行うように構成したため、ギヤ段と車速により運転状態を分別してアクセル操作量に対するスロットル操作量特性を設定していた特許文献１の従来例に比し、より少ないコストで運転性に優れたスロットル弁の制御装置を提供することができる利点を有する。 Similarly, in step S5, the throttle change amount is calculated from the current throttle opening θ and the target throttle opening θobj, and the throttle actuator 3 is driven in accordance with the calculated throttle change amount to control the opening degree of the throttle valve 1. By doing so, engine over-rotation is prevented and engine damage is prevented (step S6).
As described above, in this embodiment, the engine operating state is classified into a plurality of operation modes in the areas A to E based on the engine speed and the accelerator opening as shown in FIG. 2, and a map in each operation mode is set. Since the opening degree control of the throttle valve 1 suitable for the operating state of the engine is performed, the throttle operating amount characteristic with respect to the accelerator operating amount is set by classifying the operating state based on the gear stage and the vehicle speed. Compared to the example, there is an advantage that it is possible to provide a control device for a throttle valve that is excellent in operability at lower cost.

また、本実施形態は、領域Ｅの最高回転域の運転モードに於て、過回転防止マップを設定しているため、エンジンの過負荷を防止してエンジンの損傷を防ぐことができる利点を有する。   Further, the present embodiment has an advantage that the engine overload can be prevented and the engine can be prevented from being damaged because the overspeed prevention map is set in the operation mode in the maximum rotation range of the region E. .
