Description

この発明は、ブレーキ操作に応じた電気信号を発生させ、その電気信号に基づいて液圧アクチュエータや電動アクチュエータを制御して制動力を発生させる、所謂バイワイヤー方式の車両用ブレーキシステムに採用するのに適したブレーキ操作入力装置に関する。     The present invention is applied to a so-called by-wire type vehicle brake system that generates an electric signal corresponding to a brake operation and generates a braking force by controlling a hydraulic actuator or an electric actuator based on the electric signal. Brake operation input device suitable for

バイワイヤー方式のブレーキシステムにおいて、運転者がブレーキペダルの踏み応えにもの足りなさを感じないようにするために、下記特許文献１は、バネ定数の異なる２種類のコイルスプリング（円錐型スプリングと円筒型スプリング）を組み合わせたブレーキ操作入力装置を備えるブレーキ制御装置を提案している。   In order to prevent the driver from feeling unsatisfied with the response of the brake pedal in the by-wire brake system, the following Patent Document 1 describes two types of coil springs (conical spring and cylindrical) having different spring constants. Has proposed a brake control device including a brake operation input device combined with a mold spring.

そのブレーキ制御装置のブレーキ操作入力装置は、ブレーキペダルのストロークが設定値未満のときには円錐型スプリングのバネ力のみが反力としてブレーキペダルに作用し、一方、ブレーキペダルのストロークが設定値を超えたときには２つのスプリングのバネ力が加算されてブレーキペダルに反力として作用するように構成しており、ブレーキ操作の初期には操作力の変化に対して操作ストロークが大きく変化する所謂ストローク感のある操作フィーリングが得られ、また、ブレーキペダルのストロークが設定値を超えたときには操作力の変化に対して操作ストロークの変化が小さい所謂剛性感のある操作フィーリングが得られるようになっている。そのような操作フィーリングが良好な操作フィーリングと言われる。   In the brake operation input device of the brake control device, when the stroke of the brake pedal is less than the set value, only the spring force of the conical spring acts on the brake pedal as a reaction force, while the brake pedal stroke exceeds the set value. In some cases, the spring force of two springs is added to act as a reaction force on the brake pedal, and there is a so-called stroke feeling in which the operation stroke changes greatly with respect to the change in the operation force at the initial stage of the brake operation. An operation feeling is obtained, and when the stroke of the brake pedal exceeds a set value, a so-called rigid feeling of operation is obtained in which the change in the operation stroke is small with respect to the change in the operation force. Such an operation feeling is said to be a good operation feeling.

しかしながら、特許文献１の上記の構造で、ブレーキペダルのストロークが設定値を超えたときに好ましいとされる剛性感のある操作フィーリングが得られるようにするためには、ブレーキペダルのストロークが設定値を超えた後に圧縮される円筒型スプリングを、バネ定数の大きなものにする必要があり、そのようなスプリングは一般的に線径が太くて高価であるため、ブレーキ操作入力装置のコストを上昇させる。   However, with the above structure of Patent Document 1, in order to obtain an operation feeling with rigidity that is preferable when the stroke of the brake pedal exceeds a set value, the stroke of the brake pedal is set. Cylindrical springs that are compressed after exceeding the value need to have a large spring constant, and such springs are generally thick and expensive, thus increasing the cost of brake operation input devices. Let

また、そのブレーキ操作入力装置は、操作フィーリングがスプリングの特性のみで決定されて一定し、変更の自由度がないため、運転者の好みに応じた操作フィーリングにすることが望まれてもその要求に応えることができない。
特開平０９−２５４７７８号公報 Further, the brake operation input device is desired to have an operation feeling according to the driver's preference because the operation feeling is determined and fixed only by the characteristics of the spring and there is no freedom of change. I cannot meet that demand.
Japanese Patent Laid-Open No. 09-254778

この発明は、ブレーキ操作の初期は勿論、操作ストロークが増加したときにも良好な操作フィーリングが得られ、しかも安価なブレーキ操作入力装置を提供することを目的としている。   An object of the present invention is to provide an inexpensive brake operation input device that can obtain a good operation feeling not only at the initial stage of a brake operation but also when the operation stroke increases.

上記の目的を達成するため、この発明においては、ブレーキ操作に応じて支点を中心に回転運動してストロークするブレーキ操作部材と、このブレーキ操作部材に連結点で連結されて前記ブレーキ操作部材の操作力に応じたストロークを前記ブレーキ操作部材に付与するストロークシミュレータとを備えるブレーキ操作入力装置に、前記支点と前記連結点との間の距離を変化可能となす距離調整機構を設けた。   In order to achieve the above object, according to the present invention, a brake operation member that rotates and strokes around a fulcrum according to a brake operation, and is connected to the brake operation member at a connection point to operate the brake operation member. A brake operation input device including a stroke simulator that applies a stroke according to force to the brake operation member is provided with a distance adjustment mechanism that makes it possible to change the distance between the fulcrum and the connection point.

この発明のブレーキ操作入力装置の好ましい態様を以下に列挙する。
（１）前記距離調整機構が、前記ブレーキ操作部材のストロークの増加に応じて前記支点から前記連結点までの距離を増大させるようにしたもの。
（２）前記ストロークシミュレータを複数備え、その複数のストロークシミュレータの前記ブレーキ操作部材に対する連結時期を異ならせて前記距離調整機構を構成し、前記ブレーキ操作部材のストロークの増加に応じて前記ストロークシミュレータの連結数が増加して前記支点と前記連結点との間の距離が増大するようにしたもの。
（３）前記ストロークシミュレータが、前記ブレーキ操作部材のストロークの増加に応じて弾性変形するゴムからなる弾性部材を有し、その弾性部材の弾性変形により前記ブレーキ操作部材に対する前記弾性部材の連結領域が拡大して前記支点と前記連結点との間の距離が増大するようにしたもの。
（４）前記連結点を可動とし、かつ、その可動とした連結点を変位させる駆動機構を設けて前記距離調整機構を構成し、前記駆動機構を電気的に制御して前記支点と前記連結点との間の距離を変化させられるようにしたもの。 Preferred embodiments of the brake operation input device of the present invention are listed below.
(1) The distance adjustment mechanism increases the distance from the fulcrum to the connection point in accordance with an increase in the stroke of the brake operation member.
(2) A plurality of the stroke simulators are provided, and the distance adjusting mechanism is configured by changing the connection timing of the plurality of stroke simulators with respect to the brake operation member, and the stroke simulator is configured according to an increase in the stroke of the brake operation member. The number of connections increases so that the distance between the fulcrum and the connection point increases.
(3) The stroke simulator includes an elastic member made of rubber that is elastically deformed in response to an increase in the stroke of the brake operation member, and a connecting region of the elastic member to the brake operation member is formed by elastic deformation of the elastic member. Expanded to increase the distance between the fulcrum and the connecting point.
(4) The distance adjusting mechanism is configured by providing a driving mechanism that makes the connecting point movable and displaces the movable connecting point, and electrically controls the driving mechanism to control the fulcrum and the connecting point. The distance between can be changed.

この発明では、ブレーキ操作力とブレーキ操作ストロークの比の変化を、ブレーキ操作部材の回転運動の支点とブレーキ操作部材に対するストロークシミュレータ連結点との間の距離の変化によって起こさせる。従って、バネ定数の大きい高価なスプリングを必要とせず、コストを削減した安価なブレーキ操作入力装置を実現して提供することができる。   In the present invention, the change in the ratio between the brake operation force and the brake operation stroke is caused by the change in the distance between the fulcrum of the rotational movement of the brake operation member and the stroke simulator connection point with respect to the brake operation member. Therefore, it is possible to realize and provide an inexpensive brake operation input device that does not require an expensive spring having a large spring constant and reduces the cost.

また、前記支点と連結点との間の距離を変化させると操作フィーリングが変化するので、ブレーキ操作の初期にはストローク感があり、一方、ブレーキ操作ストロークが所定ストロークを超えたときには剛性感のある良好な操作フィーリングを得ることができる。また、前記支点と前記連結点との間の距離調整を電気的に制御される駆動機構を用いて行うようにしたものは、前記の距離の調整が自由に行えるので、運転者の好みや状況に応じた良好な操作フィーリングを得ることも可能になる。   In addition, when the distance between the fulcrum and the connection point is changed, the operation feeling changes, so that there is a feeling of stroke at the beginning of the brake operation, and on the other hand, when the brake operation stroke exceeds a predetermined stroke, the feeling of rigidity is felt. Some good operational feeling can be obtained. In addition, since the distance adjustment between the fulcrum and the connection point is performed using an electrically controlled drive mechanism, the adjustment of the distance can be freely performed. It is also possible to obtain a good operation feeling according to the above.

以下、この発明の実施の形態を添付図面の図１乃至図７に基づいて説明する。図１は、第１実施形態のブレーキ操作入力装置１を示している。この図１のブレーキ操作入力装置１は、ブレーキ操作部材（図のそれはブレーキペダル）２と、第１のストロークシミュレータ３及び第２のストロークシミュレータ４と、この発明を特徴づける距離調整機構５とで構成されている。   Embodiments of the present invention will be described below with reference to FIGS. 1 to 7 of the accompanying drawings. FIG. 1 shows a brake operation input device 1 of the first embodiment. The brake operation input device 1 shown in FIG. 1 includes a brake operation member (that is, a brake pedal) 2, a first stroke simulator 3 and a second stroke simulator 4, and a distance adjusting mechanism 5 that characterizes the present invention. It is configured.

ブレーキ操作部材２は、支点２ａを有し、入力点２ｂに操作力が加えられると支点２ａを中心に回転運動してストロークする。   The brake operation member 2 has a fulcrum 2a, and when an operation force is applied to the input point 2b, the brake operation member 2 rotates around the fulcrum 2a to make a stroke.

第１のストロークシミュレータ３は、円筒状の第１バネ座３ａと、その第１バネ座３ａ内にスライド自在に挿入した第２バネ座３ｂと、第１バネ座３ａと第２バネ座３ｂとの間に配置したコイルスプリング３ｃと、第２バネ座３ｂと一体の連結ロッド３ｄと、第２バネ座３ｂを第１バネ座３ａの筒内に保持するストッパ３ｅとで構成されている。この第１のストロークシミュレータ３は、第１バネ座３ａがピン６で固定部に、連結ロッド３ｄがピン７でブレーキ操作部材２の第１の連結点にそれぞれ連結される。   The first stroke simulator 3 includes a cylindrical first spring seat 3a, a second spring seat 3b that is slidably inserted into the first spring seat 3a, a first spring seat 3a, and a second spring seat 3b. A coil spring 3c disposed between them, a connecting rod 3d integral with the second spring seat 3b, and a stopper 3e for holding the second spring seat 3b in the cylinder of the first spring seat 3a. In the first stroke simulator 3, the first spring seat 3 a is connected to the fixing portion by the pin 6, and the connecting rod 3 d is connected to the first connecting point of the brake operation member 2 by the pin 7.

第２のストロークシミュレータ４も、第１のストロークシミュレータ３と同様、円筒状の第１バネ座４ａと、その第１バネ座４ａ内にスライド自在に挿入した第２バネ座４ｂと、第１バネ座４ａと第２バネ座４ｂとの間に配置したコイルスプリング４ｃと、第２バネ座４ｂと一体の連結ロッド４ｄと、第２バネ座４ｂを第１バネ座４ａの筒内に保持するストッパ４ｅとで構成され、第１バネ座４ａがピン８で固定部に、連結ロッド４ｄがピン９でブレーキ操作部材２の第２の連結点にそれぞれ連結される。なお、連結ロッド４ｄは、連結ロッド３ｄよりも支点２ａからの距離が大となる位置においてブレーキ操作部材２に連結される。また、この連結ロッド４ｄは、ブレーキ操作部材２に対して遊びｉｓをつけて連結されている。   Similarly to the first stroke simulator 3, the second stroke simulator 4 has a cylindrical first spring seat 4a, a second spring seat 4b slidably inserted into the first spring seat 4a, and a first spring. A coil spring 4c disposed between the seat 4a and the second spring seat 4b, a connecting rod 4d integral with the second spring seat 4b, and a stopper for holding the second spring seat 4b in the cylinder of the first spring seat 4a. 4e, the first spring seat 4a is connected to the fixed portion by the pin 8, and the connecting rod 4d is connected to the second connecting point of the brake operating member 2 by the pin 9. The connecting rod 4d is connected to the brake operation member 2 at a position where the distance from the fulcrum 2a is greater than that of the connecting rod 3d. The connecting rod 4d is connected to the brake operating member 2 with a play is.

このように構成した第１実施形態のブレーキ操作入力装置１は、ブレーキ操作部材２のストロークが所定ストロークに達するまでは操作に対する反力（以下単に反力と言う）が第１のストロークシミュレータ３からブレーキ操作部材２に加えられる。また、ブレーキ操作部材２のストロークが所定ストロークを超えると連結ロッド４ｄとピン９との間の遊びｉｓが吸収されて第２のストロークシミュレータ４がブレーキ操作部材２に実質的に連結され、この第２のストロークシミュレータ４からもブレーキ操作部材２に反力が加えられる。また、ブレーキ操作部材２に対して第２のストロークシミュレータ４が実質的に連結されると、支点２ａからストロークシミュレータ連結点までの距離が第１のストロークシミュレータ３のみが連結されている場合に比べて大きくなり、そのために、ブレーキ操作力の変化に対する操作ストロークの変化（これをＦ−Ｓ特性と言う）が小さくなり、Ｆ−Ｓ特性が図５に示すようなものになる。従って、第２のストロークシミュレータ４のコイルスプリング４ｃをバネ定数の大きな高価なものにしなくても、ブレーキ操作部材２のストロークが所定ストロークを超えたときに剛性感のある操作フィーリングを得ることができ、良好な操作フィーリングを安価なブレーキ操作入力装置で実現することが可能になる。   In the brake operation input device 1 of the first embodiment configured as described above, the reaction force to the operation (hereinafter simply referred to as reaction force) is applied from the first stroke simulator 3 until the stroke of the brake operation member 2 reaches a predetermined stroke. Applied to the brake operating member 2. Further, when the stroke of the brake operating member 2 exceeds a predetermined stroke, the play iss between the connecting rod 4d and the pin 9 is absorbed, and the second stroke simulator 4 is substantially connected to the brake operating member 2, and this first A reaction force is also applied to the brake operation member 2 from the second stroke simulator 4. Further, when the second stroke simulator 4 is substantially connected to the brake operation member 2, the distance from the fulcrum 2a to the stroke simulator connection point is more than that when only the first stroke simulator 3 is connected. Therefore, the change of the operation stroke with respect to the change of the brake operation force (this is referred to as FS characteristic) becomes small, and the FS characteristic becomes as shown in FIG. Therefore, even if the coil spring 4c of the second stroke simulator 4 is not expensive and has a large spring constant, it is possible to obtain a rigid operation feeling when the stroke of the brake operation member 2 exceeds a predetermined stroke. Therefore, it is possible to realize a good operation feeling with an inexpensive brake operation input device.

なお、第１、第２のストロークシミュレータのコイルスプリング３ｃ、４ｃは、バネ定数が同じものを用いてもよいし、異なるものを用いてもよい。コストの削減効果が損なわれない範囲でコイルスプリング４ｃのバネ定数をコイルスプリング３ｃのバネ定数よりも大きくすることができ、それによって、ブレーキ操作部材２のストロークが所定ストロークを超えたときのブレーキ操作力の変化に対する操作ストロークの変化をより小さくして操作フィーリングの剛性感をより一層高めることができる。   The coil springs 3c and 4c of the first and second stroke simulators may be the same or different from each other. The spring constant of the coil spring 4c can be made larger than the spring constant of the coil spring 3c within a range that does not impair the cost reduction effect, whereby the brake operation when the stroke of the brake operation member 2 exceeds the predetermined stroke The change in the operation stroke with respect to the change in force can be further reduced to further increase the rigidity of the operation feeling.

図２及び図３に、第２実施形態のブレーキ操作入力装置を示す。このブレーキ操作入力装置１１は、回転運動の支点１２ａを有するブレーキ操作部材（これもブレーキペダル）１２と、ゴムからなる弾性部材１３ａを備えたストロークシミュレータ１３を組み合わせて構成されている。１４はカバーで、必要に応じて設置される。ブレーキ操作部材１２の回転の支点１２ａは運転者の側に配置されている。また、弾性部材１３ａを支点１２ａに近い側を盛り上げた形状にしてブレーキ操作部材１２の裏側に配置し、この弾性部材１３ａを距離調整機構１５としても機能させるようにしている。   2 and 3 show a brake operation input device of the second embodiment. The brake operation input device 11 is configured by combining a brake operation member (also a brake pedal) 12 having a fulcrum 12a of rotational motion and a stroke simulator 13 having an elastic member 13a made of rubber. Reference numeral 14 denotes a cover, which is installed as necessary. A rotation fulcrum 12a of the brake operation member 12 is disposed on the driver side. Further, the elastic member 13a is formed on the back side of the brake operation member 12 so that the side close to the fulcrum 12a is raised, and this elastic member 13a also functions as the distance adjusting mechanism 15.

この第２実施形態のブレーキ操作入力装置１１は、ブレーキ操作部材１２の操作ストロークの増加に伴って弾性部材１３ａの弾性変形量が増加し、ブレーキ操作部材１２に対する弾性部材１３ａの連結領域が図３に示すように次第に拡大して支点１２ａからブレーキ操作部材１２に対する弾性部材１３ａの連結点までの距離が大きくなる。これによってＦ−Ｓ特性が図６に示すようなものになり、ゴムからなる弾性部材１３ａをバネ定数の大きなもの、即ち、大きな荷重に耐える断面積の大きな高価なものにしなくても、ブレーキ操作部材１２のストロークの増加に応じて徐々に剛性感が高まる良好な操作フィーリングを安価に得ることができる。   In the brake operation input device 11 of the second embodiment, the amount of elastic deformation of the elastic member 13a increases as the operation stroke of the brake operation member 12 increases, and the connection region of the elastic member 13a with respect to the brake operation member 12 is shown in FIG. As shown, the distance from the fulcrum 12a to the connecting point of the elastic member 13a with respect to the brake operating member 12 increases gradually. As a result, the FS characteristic becomes as shown in FIG. 6, and the brake operation can be performed even if the elastic member 13a made of rubber does not have a large spring constant, that is, an expensive one having a large cross-sectional area that can withstand a large load. It is possible to obtain a good operation feeling that increases the sense of rigidity gradually as the stroke of the member 12 increases.

図４は、第３実施形態のブレーキ操作入力装置である。この第３実施形態のブレーキ操作入力装置２１は、ブレーキ操作部材（図のそれはブレーキペダル）２２と、１組のストロークシミュレータ２３と、距離調整機構２５と、電子制御装置（ＥＣＵ）２６と、ブレーキ操作部材２２のストロークを検出するストロークセンサ２７と、ブレーキ操作部材２２に加えられた操作力を検出する踏力センサ２８と、ブレーキ操作入力装置２１のＦ−Ｓ特性を切り替える切り替えスイッチ２９とで構成されている。ブレーキ操作部材２２は、図１のブレーキ操作部材２と同じものであり、入力点２２ｂに操作力が加えられると支点２２ａを中心に回転運動してストロークする。   FIG. 4 shows a brake operation input device according to the third embodiment. The brake operation input device 21 according to the third embodiment includes a brake operation member (a brake pedal in the figure) 22, a set of stroke simulators 23, a distance adjustment mechanism 25, an electronic control unit (ECU) 26, a brake A stroke sensor 27 that detects the stroke of the operation member 22, a pedal force sensor 28 that detects an operation force applied to the brake operation member 22, and a changeover switch 29 that switches the FS characteristic of the brake operation input device 21. ing. The brake operation member 22 is the same as the brake operation member 2 of FIG. 1, and when an operation force is applied to the input point 22b, the brake operation member 22 rotates about the fulcrum 22a and strokes.

ストロークシミュレータ２３も、図１のストロークシミュレータ３と同一構造である。円筒状の第１バネ座２３ａと、その第１バネ座２３ａ内にスライド自在に挿入した第２バネ座２３ｂと、第１バネ座２３ａと第２バネ座２３ｂとの間に配置したコイルスプリング２３ｃと、第２バネ座２３ｂと一体の連結ロッド２３ｄと、第２バネ座２３ｂを第１バネ座２３ａの筒内に保持するストッパ２３ｅとで構成されている。   The stroke simulator 23 has the same structure as the stroke simulator 3 of FIG. A cylindrical first spring seat 23a, a second spring seat 23b slidably inserted into the first spring seat 23a, and a coil spring 23c disposed between the first spring seat 23a and the second spring seat 23b. And a connecting rod 23d integral with the second spring seat 23b, and a stopper 23e for holding the second spring seat 23b in the cylinder of the first spring seat 23a.

この第３実施形態のブレーキ操作入力装置２１は、ストロークシミュレータ２３の第１バネ座２３ａがピン３０で固定部に連結され、連結ロッド２３ｄは、ピン３１で距離調整機構２５の可動部材２５ａに連結される。   In the brake operation input device 21 of the third embodiment, the first spring seat 23a of the stroke simulator 23 is connected to the fixed portion by a pin 30, and the connecting rod 23d is connected to the movable member 25a of the distance adjusting mechanism 25 by a pin 31. Is done.

距離調整機構２５は、ブレーキ操作部材２２にスライド自在に取り付けた可動部材２５ａと、動力源のモータ２５ｂと、このモータ２５ｂからの駆動力を可動部材２５ａに伝える動力伝達要素（図のそれはラック・ピニオン）２５ｃとで構成されている。連結ロッド２３ｄは前記可動部材２５ａを介してブレーキ操作部材２２に間接的に連結されており、可動部材２５ａの移動によって支点２２ａから可動部材２５ａに対する連結ロッド２３ｄの連結点までの距離が変化する。   The distance adjusting mechanism 25 includes a movable member 25a slidably attached to the brake operation member 22, a motor 25b serving as a power source, and a power transmission element that transmits a driving force from the motor 25b to the movable member 25a (in the drawing, a rack Pinion) 25c. The connecting rod 23d is indirectly connected to the brake operating member 22 through the movable member 25a, and the distance from the fulcrum 22a to the connecting point of the connecting rod 23d with respect to the movable member 25a is changed by the movement of the movable member 25a.

この図４の第３実施形態のブレーキ操作入力装置２１は、ブレーキ操作部材２２のストロークが所定ストロークを超えたときに、モータ２５ｂを駆動してブレーキ操作部材２２の回転の支点２２ａと可動部材２５ａに対する連結ロッド２３ｄの連結点との間の距離が増大するように制御することにより、図７の実線で示すＦ−Ｓ特性を得ることができる。また、運転者の好みに応じてＦ−Ｓ特性を切り替えることもできる。切り替えスイッチ２９を操作してモータ２５ｂを駆動して支点２２ａから可動部材２５ａに対する連結ロッド２３ｄの連結点までの距離を変化させるストローク（前記所定のストローク）を変化させると操作力と操作ストロークの比の変化が起こり始めるときのストロークが変化する。従って、運転者が好むなら、図７に一点鎖線で示すようなストロークの長い特性にすることができる。また、ブレーキ操作部材の操作速度が速い、所謂急ブレーキがかけられたときには、図７に二点鎖線で示すストロークの短い特性とすることにより、短いストロークで高い制動力を発生させることができる。なお、急ブレーキがかけられたことはストロークセンサ２７からの信号に基づいて電子制御装置２６が判断し、ここからモータ２５ｂに指令を流して支点２２ａと可動部材２５ａに対する連結ロッド２３ｄの連結点との距離を増大させＦ−Ｓ特性をストロークの短い特性に切り替える。また、このときの制動力は、踏力センサ２８の出力に応じて制御すればよく、その制御も電子制御装置２６からの指令によって行う。なお、切り替えスイッチ２９の操作によりブレーキ操作部材２２が操作される前にモータ２５ｂを駆動して支点２２ａから可動部材２５ａに対する連結ロッド２３ｄの連結点までの距離を変化させるようにすれば、ブレーキ操作部材２２がストロークを開始するときのブレーキ操作力を変化させることができる。   The brake operation input device 21 according to the third embodiment of FIG. 4 drives the motor 25b when the stroke of the brake operation member 22 exceeds a predetermined stroke to rotate the fulcrum 22a and the movable member 25a of the brake operation member 22. By controlling so that the distance between the connecting rod 23d and the connecting point of the connecting rod 23d increases, the FS characteristic indicated by the solid line in FIG. 7 can be obtained. In addition, the FS characteristic can be switched according to the driver's preference. By operating the changeover switch 29 to drive the motor 25b to change the stroke (the predetermined stroke) for changing the distance from the fulcrum 22a to the connecting point of the connecting rod 23d with respect to the movable member 25a, the ratio between the operating force and the operating stroke The stroke when the change starts to change. Therefore, if the driver likes it, a characteristic having a long stroke as shown by a one-dot chain line in FIG. 7 can be obtained. Further, when a so-called sudden braking is applied where the operating speed of the brake operating member is fast, a high braking force can be generated in a short stroke by setting the characteristics of the stroke shown by the two-dot chain line in FIG. It is to be noted that the sudden braking is determined by the electronic control unit 26 based on a signal from the stroke sensor 27, from which a command is sent to the motor 25b, and the connecting point of the connecting rod 23d to the fulcrum 22a and the movable member 25a. And the FS characteristic is switched to a characteristic with a short stroke. Further, the braking force at this time may be controlled according to the output of the pedal force sensor 28, and the control is also performed by a command from the electronic control unit 26. If the distance from the fulcrum 22a to the connecting point of the connecting rod 23d with respect to the movable member 25a is changed by driving the motor 25b before the brake operating member 22 is operated by the operation of the changeover switch 29, the brake operation is performed. The brake operation force when the member 22 starts a stroke can be changed.
