Description

本発明は、変速機の摩擦伝達手段にすべりが発生しているかを判定する摩擦伝達手段の磨耗検出装置に関する。   The present invention relates to a wear detection device for friction transmission means for determining whether slip has occurred in the friction transmission means of a transmission.

従来、自動車等の車両におけるクラッチ板のすべりの有無を検査する方法として、サイドブレーキを引きギアを入れた状態でクラッチをつないだ場合に、エンジンが停止するか否かを調べ、エンジンが停止すればクラッチ板にすべりが生じてなく、反対にエンジンが停止しなければクラッチ板にすべりが生じており、そのクラッチ板は磨耗していることが判る。   Conventionally, as a method for inspecting the presence or absence of slippage of the clutch plate in a vehicle such as an automobile, when the clutch is engaged with the side brake pulled and the gear engaged, it is checked whether the engine stops and the engine is stopped. If the engine does not stop, the clutch plate slips, and it can be seen that the clutch plate is worn.

しかし、この方法では、クラッチ板の磨耗が少ない場合、クラッチ板のすべりが少ないので、上記検査を行ったときにエンジンが停止するから、正常なクラッチ板と区別することができない。このため、この方法では、クラッチ板の磨耗については、その磨耗を容易に知ることができないという問題があった。   However, this method cannot be distinguished from a normal clutch plate because the engine stops when the above inspection is performed because the clutch plate slips less when the clutch plate is less worn. For this reason, this method has a problem that the wear of the clutch plate cannot be easily known.

そこで、このような問題点を解決するものとして、特許文献1では、クラッチ板の磨耗が容易に分かるようにするため、クラッチ板が接続しているときに、エンジン回転数に基づいて検出した車速が車輪速パルスに基づいて検出した車速を所定値以上上回っている場合に警報するようにしている。   Therefore, in order to solve such problems, in Patent Document 1, in order to make it easy to understand the wear of the clutch plate, the vehicle speed detected based on the engine speed when the clutch plate is connected. Is alarmed when the vehicle speed detected based on the wheel speed pulse exceeds the predetermined value.

しかしながら、特許文献1に記載のすべり警報装置では、単純に車速パルスと所定値を比較しているだけであり、所定値は変速段によって変化するため、複数ある変速段の中で特定の変速段でしかすべりを判定することができないという問題がある。   However, in the slip warning device described in Patent Document 1, the vehicle speed pulse is simply compared with a predetermined value, and the predetermined value changes depending on the shift speed. There is a problem that the slip can only be judged.

そこで、本発明は上記問題点に解決するために、変速段に関係なくすべりを判定することができる摩擦伝達手段の磨耗検出装置を提供することを目的とする。   SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a wear detecting device for friction transmission means that can determine a slip regardless of a gear position.

上記課題を解決するために、本発明の摩擦伝達手段の磨耗検出装置は、変速機の摩擦伝達手段の磨耗を検出する摩擦伝達手段の磨耗検出装置において、前記変速機の入力回転数に関係する第1のパラメータを検出する第1の検出手段と、前記変速機の出力回転数に関係する第2のパラメータを検出する第2の検出手段と、前記第1のパラメータと前記第2のパラメータの比の時間当りの変化量を算出する算出手段と、前記第1のパラメータと前記第2のパラメータの比の時間当りの変化量と該変化量の目標値との差が所定値以上の場合、前記摩擦伝達手段にすべりが発生していると判定する判定手段とを備える。   In order to solve the above-described problems, a friction detection device wear detection apparatus according to the present invention relates to a friction transmission means wear detection device for detecting wear of a transmission friction transmission means and relates to an input rotational speed of the transmission. First detection means for detecting a first parameter, second detection means for detecting a second parameter related to the output rotational speed of the transmission, the first parameter, and the second parameter. A calculating means for calculating a change amount of the ratio per time, and a difference between the change amount of the ratio of the first parameter and the second parameter per time and a target value of the change amount is a predetermined value or more, Determination means for determining that slip has occurred in the friction transmission means.

本発明によれば、変速段によって影響を受ける事の無い、変速機の入力回転数に関連する第1のパラメータと変速機の出力回転数に関連する第2のパラメータの比の時間当たりの変化量によって摩擦伝達手段のすべりを判定するようにしたので、変速段に関係なく摩擦伝達手段のすべりを正確に検出することができる。このように、変速機の入力回転数に関連する第1のパラメータと変速機の出力回転数に関連する第2のパラメータの比の時間当たりの変化量を新たなパラメータとして導入することにより車速センサを使っても変速比の影響を無視できる。また、複数の変速段に対してそれぞれしきい値を設けて変速段毎にすべりを判定するのに比べて現在の変速機の段数の検出を行う必要が無いため処理を簡素化することができる。   According to the present invention, the change over time of the ratio of the first parameter related to the input rotational speed of the transmission and the second parameter related to the output rotational speed of the transmission, which is not affected by the shift speed. Since the slip of the friction transmission means is determined based on the amount, it is possible to accurately detect the slip of the friction transmission means regardless of the shift speed. Thus, the vehicle speed sensor is introduced by introducing, as a new parameter, the amount of change per time of the ratio of the first parameter related to the input rotational speed of the transmission and the second parameter related to the output rotational speed of the transmission. Even if is used, the influence of the gear ratio can be ignored. In addition, it is not necessary to detect the current number of transmission stages, as compared with the case where a threshold value is provided for each of the plurality of shift stages and the slip is determined for each shift stage, so that the processing can be simplified. .

また本発明の摩擦伝達手段の磨耗検出装置は、前記摩擦伝達手段の締結を検知する検知手段をさらに備え、前記判定手段は、前記磨耗伝達手段が締結されているとき、前記磨耗伝達手段のすべりを判定することを特徴とする。   The wear detection device for friction transmission means of the present invention further comprises detection means for detecting the fastening of the friction transmission means, and the determination means is a slip of the wear transmission means when the wear transmission means is fastened. It is characterized by determining.

前記判定手段は、前記第1のパラメータと前記第2のパラメータの比の時間当りの変化量が変化している期間が所定時間以下の場合には、該期間の変化量に基づいて前記摩擦伝達手段のすべり判定を行わないことを特徴とする。本発明によれば、摩擦伝達手段の入出力に直接センサを設けることなく磨耗伝達手段が連結されているかどうかを判別することができる。   When the period during which the amount of change per time of the ratio between the first parameter and the second parameter is changing is equal to or shorter than a predetermined time, the determination means is configured to transmit the friction transmission based on the amount of change in the period. It is characterized in that the slip determination of the means is not performed. According to the present invention, it is possible to determine whether or not the wear transmission means is connected without providing a sensor directly at the input / output of the friction transmission means.

前記第1のパラメータはエンジン回転数であり、前記第2のパラメータは車速である。   The first parameter is an engine speed, and the second parameter is a vehicle speed.

本発明によれば、変速段に関係なくすべりを判定することができる摩擦伝達手段の磨耗検出装置を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the abrasion detection apparatus of the friction transmission means which can determine a slide irrespective of a gear stage can be provided.

以下、本発明を実施するための最良の形態について説明する。図1は、本発明の実施例に係る摩擦伝達手段の磨耗検出装置を説明するための図である。図1には、車両のエンジン10に連結されるクラッチ20、変速機30、クラッチ検出スイッチ40、車輪50、車速センサ60、制御装置(ECU:Engine Control Unit)70および警報手段80を示している。制御装置70が磨耗検出装置である。   Hereinafter, the best mode for carrying out the present invention will be described. FIG. 1 is a diagram for explaining a wear detecting device for friction transmission means according to an embodiment of the present invention. FIG. 1 shows a clutch 20, a transmission 30, a clutch detection switch 40, a wheel 50, a vehicle speed sensor 60, a control device (ECU: Engine Control Unit) 70, and an alarm means 80 that are connected to the engine 10 of the vehicle. . The control device 70 is a wear detection device.

エンジン10から出力された動力は、クラッチ20、変速機30、左右の車軸などを経て車輪50へ伝達される。クラッチ20は、ここでは摩擦クラッチで、乾式発進クラッチを用いている。このクラッチ20は、クラッチ板20aとプレッシャープレート20bとが互いに対向するように設けられている。変速機30は、歯車式変速機のトランスミッションである。   The power output from the engine 10 is transmitted to the wheels 50 through the clutch 20, the transmission 30, the left and right axles, and the like. Here, the clutch 20 is a friction clutch and uses a dry start clutch. The clutch 20 is provided so that the clutch plate 20a and the pressure plate 20b face each other. The transmission 30 is a transmission of a gear transmission.

クラッチ検出スイッチ40は、クラッチ板20aとプレッシャープレート20bとからなる摩擦クラッチの締結を検出するものであり、従来のマニュアルトランスミッション車には存在しない為、本発明の実施のために設けたものである。車速センサ60は、車輪50を回転させる車軸の回転数を検出する。   The clutch detection switch 40 detects the engagement of the friction clutch composed of the clutch plate 20a and the pressure plate 20b, and is not provided in the conventional manual transmission vehicle, and is provided for carrying out the present invention. . The vehicle speed sensor 60 detects the rotational speed of the axle that rotates the wheel 50.

制御装置70は、車速検出手段71、エンジン回転数検出手段72、車速比算出手段73、速度比変化量算出手段74、クラッチ判別手段75およびすべり判定手段76を備える。車速検出手段71は、車速センサ60が検出した車軸の回転数に基づいて変速機の出力回転数に関係する第2のパラメータとして車速を検出するものである。   The control device 70 includes a vehicle speed detection means 71, an engine speed detection means 72, a vehicle speed ratio calculation means 73, a speed ratio change amount calculation means 74, a clutch determination means 75, and a slip determination means 76. The vehicle speed detecting means 71 detects the vehicle speed as a second parameter related to the output rotational speed of the transmission based on the rotational speed of the axle detected by the vehicle speed sensor 60.

エンジン回転数検出手段72は、変速機30の入力回転数に関係する第1のパラメータとしてエンジン回転数を検出するものである。このエンジン回転数検出手段72は、例えばエンジンの出力シャフトの回転数をエンジン回転数として検出する。   The engine speed detecting means 72 detects the engine speed as a first parameter related to the input speed of the transmission 30. The engine speed detection means 72 detects, for example, the speed of the output shaft of the engine as the engine speed.

速度比算出手段73は、第1のパラメータであるエンジン回転数と第2のパラメータである速度の比を算出する。具体的には、速度比算出手段73は、速度比を速度(V)/エンジン回転数(EGREV)により求める。ここで、速度比は、変速機30の変速段によって異なるものである。そこで、本発明では変速段によって影響を受けることがないエンジン回転数と速度の比の時間当りの変化量を新たなパラメータとして導入し、このパラメータをクラッチのすべり判定に用いることにより変速段によって影響を受けないクラッチのすべり判定を実現している。   The speed ratio calculating means 73 calculates the ratio between the engine speed, which is the first parameter, and the speed, which is the second parameter. Specifically, the speed ratio calculation means 73 obtains the speed ratio by speed (V) / engine speed (EGREV). Here, the speed ratio varies depending on the gear stage of the transmission 30. Therefore, in the present invention, the amount of change per hour in the ratio of the engine speed and speed that is not affected by the shift speed is introduced as a new parameter, and this parameter is used to determine the slippage of the clutch, thereby affecting the shift speed. The slip judgment of the clutch which does not receive is realized.

速度比変化量算出手段74は、速度比算出手段73が求めた速度比に基づいて、エンジン回転数と速度の比の時間当りの変化量を算出する。具体的には、速度比変化量算出手段74は、(1)式に示すように、速度比算出手段73が求めた速度比を時間微分することによりエンジン回転数と速度の比の時間当たりの変化量を算出する。
・エンジン回転数と速度の比の時間当たりの変化量=d(V/EGREV)/dt ・・・(1)
クラッチ判定手段75は、クラッチ検出スイッチ40の検出結果に基づいて摩擦伝達手段であるクラッチ20の締結を検知するものである。すべり判定手段76は、エンジン回転数と速度の比の時間当りの変化量と変化量の目標値との差が所定値以上の場合、クラッチ20にすべりが発生していると判定する。尚、ここではすべり判定手段76は、クラッチ判別手段75によりクラッチが締結されている場合にのみ、クラッチのすべりを判定するようにしている。そして、すべり判定手段76は、判定結果の信号を警報手段80に出力する。
The speed ratio change amount calculating means 74 calculates the amount of change per hour in the ratio of the engine speed and speed based on the speed ratio obtained by the speed ratio calculating means 73. Specifically, the speed ratio change amount calculating means 74, as shown in equation (1), differentiates the speed ratio obtained by the speed ratio calculating means 73 with respect to time so that the ratio of the engine speed to the speed per time. The amount of change is calculated.
・ Change amount of engine speed / speed ratio per time = d (V / EGREV) / dt (1)
The clutch determination means 75 detects the engagement of the clutch 20 that is a friction transmission means based on the detection result of the clutch detection switch 40. The slip determination means 76 determines that slip has occurred in the clutch 20 when the difference between the amount of change in the engine speed / speed ratio per time and the target value of the change amount is equal to or greater than a predetermined value. Here, the slip judging means 76 judges the slip of the clutch only when the clutch discriminating means 75 is engaged. Then, the slip determination unit 76 outputs a determination result signal to the alarm unit 80.

警報手段80は、すべり判定手段76の判定結果の信号に基づいてすべりが生じていることを利用者に報知する。ここで、警報手段80は、視覚的に警報する場合には例えばLEDなどの発光素子や他の表示手段により構成され、音声により警報する場合には例えばスピーカにより構成される。   The warning unit 80 notifies the user that a slip has occurred based on the signal of the determination result of the slip determination unit 76. Here, the alarm means 80 is configured by a light emitting element such as an LED or other display means when visually alarming, and is configured by a speaker when alarming by voice.

図2(a)は速度比を示す図、同図(b)はエンジン回転数と速度の比の時間当たりの変化量を示す図である。図2(a)に示すように、速度比は、変速機30の変速段によって異なるものである。このため、この速度比をクラッチのすべり判定に用いると、すべり判定に用いるしきい値を一つしか用意していない場合には特定の変速段でしかクラッチのすべり判定を行うことができない。また複数ある変速段ごとにしきい値を用意することにより複数ある変速段毎にすべりを判定することもできるが、現在の変速段の段数も検出する必要があるためすべり判定処理が複雑になる。   FIG. 2A is a diagram showing the speed ratio, and FIG. 2B is a diagram showing the amount of change per hour in the ratio of engine speed and speed. As shown in FIG. 2A, the speed ratio varies depending on the gear position of the transmission 30. For this reason, if this speed ratio is used for clutch slip determination, if only one threshold value is used for slip determination, clutch slip determination can be performed only at a specific shift stage. In addition, it is possible to determine the slip for each of a plurality of shift stages by preparing a threshold value for each of a plurality of shift stages, but the slip determination process becomes complicated because it is necessary to detect the number of stages of the current shift stage.

そこで、本発明では、図2(b)に示すように、変速段によって影響を受けることがないエンジン回転数と速度の比の時間当りの変化量を新たなパラメータとして導入し、このパラメータをクラッチのすべり判定に用いることにより変速段によって影響を受けないクラッチのすべり判定を実現している。   Therefore, in the present invention, as shown in FIG. 2 (b), a change amount per hour of the ratio of the engine speed and the speed that is not affected by the shift speed is introduced as a new parameter, and this parameter is applied to the clutch. By using this for slip determination, clutch slip determination that is not affected by the shift speed is realized.

また、同図(b)に示すように、変速機30が1速から2速、又2速から3速に切り替わるときは、スパイクのため、エンジン回転数と速度の比の時間当りの変化量は安定しない値となる。そこで、すべり判定手段76は、エンジン回転数と車速の比の時間当りの変化量が変化している期間が所定時間(tx)以下の場合には、この期間はクラッチ20が連結されていないと判断して該期間の変化量に基づいてクラッチ20のすべり判定を行わない。これにより、クラッチ検出スイッチ40とクラッチ判別手段75を設けることなく、クラッチ20が連結されているかを判別することができる。   Also, as shown in FIG. 4B, when the transmission 30 is switched from the 1st speed to the 2nd speed, or from the 2nd speed to the 3rd speed, the amount of change per hour in the ratio of the engine speed to the speed due to the spike. Becomes an unstable value. Therefore, the slip determination means 76 determines that the clutch 20 is not engaged during this period when the period in which the amount of change per hour in the ratio between the engine speed and the vehicle speed changes is equal to or shorter than the predetermined time (tx). The slip determination of the clutch 20 is not performed based on the amount of change in the period. Thus, it is possible to determine whether the clutch 20 is connected without providing the clutch detection switch 40 and the clutch determination means 75.

上述したように、本発明の実施例によれば、変速段によって影響を受ける事の無い、変速機の入力回転数に関連する第1のパラメータと変速機の出力回転数に関連する第2のパラメータの比の時間当たりの変化量によって摩擦伝達手段のすべりを判定するようにしたので、変速段に関係なく摩擦伝達手段のすべりを正確に検出することができる。   As described above, according to the embodiment of the present invention, the first parameter related to the input rotational speed of the transmission and the second related to the output rotational speed of the transmission are not affected by the shift speed. Since the slip of the friction transmission means is determined based on the amount of change in the parameter ratio per time, the slip of the friction transmission means can be accurately detected regardless of the gear position.

以上本発明の好ましい実施例について詳述したが、本発明は係る特定の実施例に限定されるものではなく、特許請求の範囲に記載された本発明の要旨の範囲内において、種々の変形、変更が可能である。   Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications, within the scope of the gist of the present invention described in the claims, It can be changed.
