Description

【０００１】
【産業上の利用分野】
本発明は、自動車に利用する。本発明は、市内を走行する定期バスに利用する車両のために開発された装置であるが、定期バス用の車両以外の自動車にも広く実施することができる。本発明は、内燃機関（ガソリン・エンジンおよびディーゼル・エンジンを含む）の停止操作を行うことなく、一定の条件で自動的にその内燃機関の運転を停止させ、その自動停止した内燃機関について一定の条件で自動的に再度始動させるための装置に関する。本発明は、クラッチペダルのないオートマチック車に利用するための装置である。
【０００２】
【従来の技術】
市内を走行する定期バスでは、停留所に停車して乗客が乗り降りする間にも、大気汚染あるいは二酸化炭素の排出を少なくするために、アイドリング状態にある内燃機関を停止することが推奨されている。しかし、その内燃機関の停止および再始動のための運転操作がわずらわしいために、一定の条件で自動的に内燃機関を停止させ、かつ再始動させる装置が利用されるようになった。
【０００３】
このような装置は、プロセッサを用いた論理回路を備え、サービスブレーキが踏まれ、クラッチが踏まれ、車速が減速して車速零となる経過を経た後に、変速ギヤをニュートラル位置に設定してからクラッチペダルを離すと、内燃機関が自動的に運転を停止するように構成されている。そして、その自動停止した状態でクラッチペダルを踏むと、内燃機関は自動的に再始動するように構成されている。この自動停止装置あるいは自動始動装置は、バスが乗客の乗り降りのために停留所に停車する際に、運転者の特別な操作がなくとも自動的に内燃機関の停止および再始動が行われる。
【０００４】
【発明が解決しようとする課題】
上記のような装置は市内走行用の定期バスに利用され広く普及した。またこのような装置はトラックなど大型の商業車にも装備されて、信号待ちや道路渋滞の時に内燃機関を特別の運転操作を行うことなく自動的に停止させ、自動的に再始動する装置として利用されるようになった。ところが、クラッチペダルのないオートマチック車では、クラッチペダルの操作に関連する論理で内燃機関の自動停止および自動再始動を行うことができない。
【０００５】
本発明はこのような背景に行われたものであって、クラッチペダルのないオートマチック車に利用するための内燃機関の自動停止装置および自動始動装置を提供することを目的とする。本発明は、オートマチック車で停車中の内燃機関の自動停止および自動停止後の再始動を行うための装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明は、クラッチペダルのないオートマチック車の内燃機関を一定の条件が成立したときに自動的に停止させ、この自動停止の状態で一定の条件が成立したときに再始動させることを特徴とする。
【０００７】
すなわち、本発明の第一の観点は、内燃機関の自動停止装置であって、ブレーキセンサの出力がブレーキ作動状態にあり、車速が零値になった時点からｔ秒後に、内燃機関を自動的に停止させる論理手段を備えたことを特徴とする。すなわち、所定値を越える車速を経験し、車速が最初に零値になり、引きつづきｔ秒間にわたり車速が零値であるときに内燃機関を操作によらずに自動停止させる。
【０００８】
変速レバーの設定位置にかかわらず前記論理手段が起動し内燃機関が停止する前に変速ギヤを自動的にニュートラル位置に設定する手段を備えることが望ましい。内燃機関が停止すると制御油圧が急速に低下するから、停止の前、望ましくは直前に変速ギヤを設定することがよい。
【０００９】
本発明の第二の観点は、内燃機関の自動始動装置であって、運転者がその左足で操作するスイッチを設け、上記論理手段により内燃機関が自動停止された状態で、かつブレーキが作動状態であるとき、前記左足で操作するスイッチが操作されたときに、その内燃機関を自動的に始動させる論理手段を備えたことを特徴とする。
【００１０】
前記始動させる論理手段は、内燃機関の始動後に変速ギヤを前記変速レバーの設定位置に自動的に設定する手段を含むことが望ましい。
【００１１】
本発明の第三の観点は、内燃機関の自動停止を一時的に無効とする装置であって、ブレーキが作動状態で車速が零値になる時点で、左足で操作するスイッチが操作されているときには内燃機関の自動停止を禁止する手段を含むことを特徴とする。
【００１２】
ブレーキ・ペダルが踏まれブレーキが作動状態にあることを示す出力があり、左足で操作するスイッチによる再始動の指示入力がない状態で、ブレーキ作動により車速が零値を示した時点を基点としてｔ秒（例えば１．５秒）零値のまま経過したときには、運転者が停車を意図しているものとして内燃機関を自動的に停止する。
【００１３】
このような内燃機関の自動停止が行われたときには、変速レバーがどの位置に設定されていても、変速ギヤを自動的にニュートラル位置に設定する。これにより何らかの原因で車両が発進してしまうようなことを避けることができる。
【００１４】
ブレーキ操作により車速が零値を示した時点を起点としてｔ秒経過したことにより内燃機関が自動停止した状態にあって、ブレーキペダルが踏まれたまま左足で操作するスイッチが操作されたときは、運転者が発進を意図しているものとして内燃機関を通常の始動操作を行うことなく始動させる。このように始動動作がブレーキ・ペダルが踏まれブレーキが作動している状態で行われるので安全な状態を維持することができる。
【００１５】
このようにして内燃機関が自動始動されると、自動停止時にニュートラル位置にあった変速ギヤを変速レバーが設定されている位置に自動的に投入する。ただし、変速レバーがニュートラル位置にあればひきつづきニュートラル位置とする。このように自動停止時には変速ギヤ位置がニュートラル位置にあって、運転者の発進を意識したスイッチ操作によって自動始動が行われた後に変速ギヤが運転者の意図した位置に設定されるので、運転者がそのつどギヤ操作を行うことが不要であるとともに、車両が不意に発進してしまうようなことを避けることができる。
【００１６】
左足で操作するスイッチがブレーキ操作により車速が零になる時点で操作されているとき、すなわち、車速が零になる前から操作されているときは、運転者が内燃機関の自動停止を行わない意図であるものとして自動停止動作を禁止する。この禁止動作によりきわめて短い時間だけ停車したいときに自動停止が行われ、その後ただちに自動始動するような無益な動作を避けることができる。
【００１７】
このように、本発明によればクラッチペダルのないオートマチック車であっても、停車中の内燃機関の自動停止および自動停止後の自動始動を行うことができ、大気汚染あるいは二酸化炭素の排出を少なくする社会的背景に沿った車両運行を行うことができる。
【００１８】
【発明の実施の形態】
【００１９】
【実施例】
次に、本発明実施例を図面に基づいて説明する。図１は本発明実施例の要部の構成を示すブロック図、図２は本発明実施例における再始動スイッチの運転室内の配置位置を示す図である。
【００２０】
本発明実施例は、運転席に運転者がその左足で操作するスイッチとして再始動スイッチ１が設けられ、制御情報を取込み内燃機関の自動停止および自動始動を制御する制御回路１０が備えられる。
【００２１】
制御回路１０には、ブレーキセンサ２の出力がブレーキ作動状態にあり車速が零値になった時点を基点としｔ秒（例えば１．５秒）を経過するまでひきつづき零値であるときに内燃機関を自動的に停止させる手段、内燃機関が自動停止した状態で再始動スイッチ１が操作されたときにその内燃機関を自動的に始動させる手段、および左足で操作する再始動スイッチ１が操作されたときにその内燃機関を自動的に始動させる手段を含む論理手段１１と、変速レバー３の設定位置にかかわらず論理手段１１により内燃機関が停止する前に変速ギヤを自動的にニュートラル位置に設定する手段と、内燃機関の始動後に変速ギヤを変速レバー３の設定位置に自動的に設定する手段と、左足で操作する再始動スイッチ１が車速が零になる時点で操作されているときには内燃機関の自動停止を禁止する手段とが含まれる。
【００２２】
制御回路１０には、運転者が左足で操作する再始動スイッチ１、ブレーキの作動状態を検出するブレーキセンサ２、変速位置を設定する変速レバー３、車両の走行速度を検出する車速センサ４、およびアイドル・ストップ・システムの起動または停止を行うアイドル・ストップ・スイッチ５の出力が接続される。アイドル・ストップ・スイッチは運転席のダッシュボードに設けられた手動のスイッチであり、このシステム全体をオン・オフするために利用する。
【００２３】
また、制御回路１０からは、内燃機関への燃料供給を遮断する燃料遮断バルブ６、内燃機関の始動を行う始動電動機７、および変速機８を操作して自動変速を行う自動変速制御手段９に制御信号が送出される。
【００２４】
次に、このように構成された本発明実施例の動作について説明する。図３は本発明実施例における内燃機関の自動停止動作の流れを示すフローチャート、図４は本発明実施例における内燃機関の自動始動動作の流れを示すフローチャートである。
【００２５】
まず、図１および図３を参照して本発明実施例による内燃機関自動停止動作について説明する。制御回路１０の論理手段１１はブレーキセンサ２、車速センサ４および再始動スイッチ１の出力を取込み、ブレーキが作動状態にあることを示すオン信号（１）が出力され、車両が停車状態にあることを示す停車信号（０）が出力され、かつ再始動スイッチ１が踏まれていない状態を示すオフ信号（０）が出力されて、車速が所定値ｖ0 から最初に零値になった時点後にｔ秒（例えば１．５秒）経過したときは、運転者が停車を意図してブレーキ操作を行ったものとして、自動変速制御手段９に制御信号を送出し、変速レバー３の位置（１、２、Ｄ、Ｒ）にかかわらず変速機８の変速ギヤをニュートラルの位置に自動的に設定し、燃料遮断バルブ６に制御信号を送出し燃料供給を遮断して内燃機関を停止する。この燃料遮断バルブ６は自動停止後に自動的に解放される。これにより運転者が手動操作により始動を行うことを妨げないようにする。
【００２６】
再始動スイッチ１が車速が零値になる時点、すなわち車速が零値を示す前からすでに操作されているときには、車速センサ４が停車状態を示す信号（０）が出力されていても、再始動スイッチ１の出力がオン信号（１）を示しているので、燃料遮断バルブ６への制御信号の出力は行われず内燃機関の自動停止は禁止される。
【００２７】
このような操作は、例えば路線バスで１人あるいは２人程度の乗降客があるきわめて短い停車の場合に行われ、この操作が行われることによって、内燃機関の自動停止後にただちに自動始動を行うような無益な操作を避けることができる。
【００２８】
次に、図１および図４を参照して本発明実施例による内燃機関の自動始動動作について説明する。運転席に設けられたアイドル・ストップ・スイッチ５が操作されて自動変速モードを設定するオン信号が出力されているときには、ブレーキ・ペダルが踏まれブレーキが作動して内燃機関が停止した状態にあるときに、再始動スイッチ１が操作されると、論理手段１１は燃料遮断バルブ６および始動電動機７に制御信号を送出して、燃料遮断バルブ６を開状態にするとともに、始動電動機を駆動して内燃機関を自動的に始動する。
【００２９】
内燃機関が自動始動すると自動変速制御手段９に制御信号を送出し、変速ギヤをニュートラル位置からレバー設定位置に自動的に設定する。
【００３０】
【発明の効果】
以上説明したように本発明によれば、従来オートマチック車において実施されなかった内燃機関の自動停止および自動停止後の始動始動を行うことができ、大気汚染あるいは二酸化炭素の排出を少なくする社会的背景に沿った車両の運行を行うことができる。
【００３１】
また、車両の運行操作においてきわめて短い時間の停車を行うときには、あいている左足によるスイッチ操作により自動停止が禁止されるので、無益な内燃機関の自動停止および自動始動を回避することができる。

[Industrial application fields]
The present invention is used for automobiles. Although the present invention is an apparatus developed for a vehicle used for a regular bus traveling in the city, it can be widely applied to automobiles other than vehicles for regular buses. The present invention automatically stops the operation of the internal combustion engine under certain conditions without stopping the internal combustion engine (including a gasoline engine and a diesel engine). The present invention relates to an apparatus for automatically starting again under conditions. The present invention is an apparatus for use in an automatic vehicle without a clutch pedal.
[0002]
[Prior art]
In regular buses traveling in the city, it is recommended to stop idling internal combustion engines to reduce air pollution or carbon dioxide emissions even when passengers get on and off the bus at the stop. . However, since the operation for stopping and restarting the internal combustion engine is cumbersome, an apparatus for automatically stopping and restarting the internal combustion engine under certain conditions has come to be used.
[0003]
Such a device is equipped with a logic circuit using a processor, and after the service brake is depressed, the clutch is depressed, the vehicle speed is decelerated and the vehicle speed becomes zero, and then the transmission gear is set to the neutral position. When the clutch pedal is released, the internal combustion engine is automatically stopped. When the clutch pedal is stepped on in the automatically stopped state, the internal combustion engine is automatically restarted. This automatic stop device or automatic start device automatically stops and restarts the internal combustion engine without any special operation by the driver when the bus stops at a stop for passengers getting on and off.
[0004]
[Problems to be solved by the invention]
Such devices have been widely used for regular buses for city travel. In addition, such devices are also installed in large commercial vehicles such as trucks, and automatically stop and restart the internal combustion engine without special operation when waiting for traffic lights or traffic jams. It came to be used. However, in an automatic vehicle without a clutch pedal, the internal combustion engine cannot be automatically stopped and restarted by the logic related to the operation of the clutch pedal.
[0005]
The present invention has been made against such a background, and an object thereof is to provide an automatic stop device and an automatic start device for an internal combustion engine for use in an automatic vehicle without a clutch pedal. An object of the present invention is to provide an apparatus for automatically stopping an internal combustion engine stopped by an automatic vehicle and restarting the engine after the automatic stop.
[0006]
[Means for Solving the Problems]
The present invention is characterized in that an internal combustion engine of an automatic vehicle without a clutch pedal is automatically stopped when a certain condition is satisfied, and is restarted when a certain condition is satisfied in this automatic stop state. .
[0007]
That is, the first aspect of the present invention is an automatic stop device for an internal combustion engine, in which the internal combustion engine is automatically turned off after t seconds from the time when the output of the brake sensor is in a brake operation state and the vehicle speed becomes zero. It is characterized in that it is provided with logic means for stopping. That is, when the vehicle speed exceeds a predetermined value, the vehicle speed first becomes zero, and when the vehicle speed remains zero for t seconds, the internal combustion engine is automatically stopped without operation.
[0008]
It is desirable to provide means for automatically setting the transmission gear to the neutral position before the logic means is activated and the internal combustion engine is stopped regardless of the transmission lever setting position. When the internal combustion engine is stopped, the control oil pressure rapidly decreases. Therefore, it is preferable to set the transmission gear before stopping, preferably immediately before.
[0009]
According to a second aspect of the present invention, there is provided an automatic starter for an internal combustion engine, comprising a switch operated by a driver with its left foot, wherein the internal combustion engine is automatically stopped by the logic means, and the brake is in an activated state. When the switch operated with the left foot is operated, a logic means for automatically starting the internal combustion engine is provided.
[0010]
Preferably, the logic means for starting includes means for automatically setting the transmission gear to the set position of the transmission lever after the internal combustion engine is started.
[0011]
A third aspect of the present invention is a device for temporarily disabling automatic stop of an internal combustion engine, and a switch operated with a left foot is operated at the time when the brake is in an operating state and the vehicle speed becomes zero. Sometimes it includes means for prohibiting the automatic stop of the internal combustion engine.
[0012]
There is an output indicating that the brake pedal is depressed and the brake is in the active state, and there is no restart instruction input by the switch operated with the left foot, and the time point when the vehicle speed becomes zero by the brake operation is t When the zero value elapses for 2 seconds (for example, 1.5 seconds), the internal combustion engine is automatically stopped assuming that the driver intends to stop.
[0013]
When such an internal combustion engine is automatically stopped, the transmission gear is automatically set to the neutral position regardless of the position of the transmission lever. As a result, it is possible to prevent the vehicle from starting for some reason.
[0014]
When a switch operated with the left foot is operated while the internal combustion engine is automatically stopped because t seconds have elapsed from the time when the vehicle speed has become zero by the brake operation, and the brake pedal is depressed, Assuming that the driver intends to start, the internal combustion engine is started without performing a normal start operation. Thus, since the starting operation is performed in a state where the brake pedal is depressed and the brake is operated, a safe state can be maintained.
[0015]
When the internal combustion engine is automatically started in this manner, the transmission gear that was in the neutral position at the time of automatic stop is automatically put into the position where the transmission lever is set. However, if the speed change lever is in the neutral position, it will continue to be in the neutral position. Thus, when the automatic transmission is stopped, the transmission gear position is in the neutral position, and after the automatic start is performed by the switch operation in consideration of the driver's start, the transmission gear is set at the position intended by the driver. However, it is not necessary to operate the gear each time, and it is possible to prevent the vehicle from starting unexpectedly.
[0016]
When the switch operated with the left foot is operated when the vehicle speed becomes zero due to the brake operation, that is, when the switch is operated before the vehicle speed becomes zero, the driver intends not to automatically stop the internal combustion engine. As a result, the automatic stop operation is prohibited. Due to this prohibition operation, it is possible to avoid a useless operation in which an automatic stop is performed when it is desired to stop the vehicle for a very short time, and the automatic start immediately thereafter.
[0017]
Thus, according to the present invention, even an automatic vehicle without a clutch pedal can automatically stop the internal combustion engine that is stopped and automatically start after the automatic stop, thereby reducing air pollution or emission of carbon dioxide. The vehicle can be operated according to the social background.
[0018]

First, an internal combustion engine automatic stop operation according to an embodiment of the present invention will be described with reference to FIGS. The logic means 11 of the control circuit 10 takes in the outputs of the brake sensor 2, the vehicle speed sensor 4 and the restart switch 1, outputs an ON signal (1) indicating that the brake is in an operating state, and the vehicle is in a stopped state. stop signal indicating the (0) is output, and oFF signal indicating the state where the restart switch 1 is not depressed (0) is output, after the time when the vehicle speed becomes a first zero value from the predetermined value v 0 When t seconds (e.g., 1.5 seconds) have elapsed, it is assumed that the driver has performed a brake operation with the intention of stopping, and a control signal is sent to the automatic transmission control means 9 so that the position (1, Regardless of (2, D, R), the transmission gear of the transmission 8 is automatically set to the neutral position, a control signal is sent to the fuel cutoff valve 6, the fuel supply is shut off, and the internal combustion engine is stopped. The fuel cutoff valve 6 is automatically released after the automatic stop. As a result, the driver is not prevented from starting manually.
[0026]
When the restart switch 1 is already operated before the vehicle speed reaches the zero value, that is, before the vehicle speed reaches the zero value, the restart is performed even if the signal (0) indicating that the vehicle speed sensor 4 is stopped is output. Since the output of the switch 1 indicates the ON signal (1), the control signal is not output to the fuel cutoff valve 6 and the automatic stop of the internal combustion engine is prohibited.
[0027]
Such an operation is performed, for example, in the case of a very short stop where there are about one or two passengers on a route bus. By performing this operation, an automatic start is performed immediately after the internal combustion engine is automatically stopped. Can avoid unnecessary operations.
[0028]
Next, the automatic start operation of the internal combustion engine according to the embodiment of the present invention will be described with reference to FIG. 1 and FIG. When the idle stop switch 5 provided in the driver's seat is operated to output an ON signal for setting the automatic transmission mode, the brake pedal is depressed, the brake is activated, and the internal combustion engine is stopped. Sometimes, when the restart switch 1 is operated, the logic means 11 sends a control signal to the fuel shutoff valve 6 and the starter motor 7 to open the fuel shutoff valve 6 and drive the starter motor. The internal combustion engine is automatically started.
[0029]
When the internal combustion engine is automatically started, a control signal is sent to the automatic transmission control means 9 to automatically set the transmission gear from the neutral position to the lever setting position.
[0030]
【The invention's effect】
As described above, according to the present invention, it is possible to perform an automatic stop of an internal combustion engine and a start-up after an automatic stop that have not been performed in an automatic vehicle in the past, and a social background that reduces air pollution or emission of carbon dioxide. The vehicle can be operated along.
[0031]
Further, when stopping the vehicle for a very short time in the operation of the vehicle, automatic stop is prohibited by the switch operation by the left foot that is open, so that unnecessary automatic stop and automatic start of the internal combustion engine can be avoided.
