Description

本発明は、鞍乗り型車両に関するものである。 The present invention relates to a saddle- ride type vehicle.

従来、方向指示器を車幅方向内方から車幅方向外方に向けて光が移動するように点灯させる、いわゆるシーケンシャル点灯の方向指示装置がある（例えば、特許文献１参照）。特許文献１には、光を導光する性質を有するターン導光部と、車幅方向に設けられた複数の発光ダイオードと、を備え、複数の発光ダイオードを車幅方向内側の部位から車幅方向外側の部位に向けて点灯させることにより、ターン導光部をシーケンシャル状に発光させる方向指示手段が開示されている。 2. Description of the Related Art Conventionally, there is a so-called sequential lighting direction indicator device that lights a direction indicator so that light moves from the inside in the vehicle width direction to the outside in the vehicle width direction (see, for example, Patent Document 1). In Patent Document 1, a turn light guide portion having a property of guiding light and a plurality of light emitting diodes provided in the vehicle width direction are provided. A direction indicating means is disclosed that causes the turn light guides to emit light sequentially by illuminating them toward the outer side of the direction.

特開２０１５－９９６５４号公報JP 2015-99654 A

しかしながら、従来のシーケンシャル点灯の方向指示装置を鞍乗り型車両に適用する場合には、車幅方向の寸法の制限などレイアウトの都合により、光源の数に制約が生じる可能性がある。光源の数が少なくなるに従い、シーケンシャル点灯の目的である流動的な点灯が難しくなる。 However, when a conventional sequential lighting turn indicator device is applied to a saddle-ride type vehicle, there is a possibility that the number of light sources may be restricted due to layout considerations such as vehicle width dimension restrictions. Fluid lighting, which is the purpose of sequential lighting, becomes more difficult as the number of light sources decreases.

そこで本発明は、少ない光源で流動的な点灯が可能な方向指示装置を備えた鞍乗り型車両を提供するものである。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a saddle-riding vehicle equipped with a direction indicating device capable of fluid lighting with a small number of light sources.

本発明の方向指示装置は、方向指示のために発光を行う第１光源（１１）および第２光源（１２）と、前記第１光源（１１）および前記第２光源（１２）を収容するハウジング（２０）と、前記第１光源（１１）および前記第２光源（１２）を制御する制御部（４）と、を備え、前記制御部（４）は、前記第１光源（１１）を第１発光態様で発光させるとともに、前記第１光源（１１）の発光と重複して前記第２光源（１２）を前記第１発光態様とは異なる第２発光態様で発光させ、前記第１発光態様の輝度の減少時に前記第２発光態様の輝度が増加する、ことを特徴とする。 The direction indicator device of the present invention comprises a first light source (11) and a second light source (12) that emit light for direction indication, and a housing containing the first light source (11) and the second light source (12). (20), and a control section (4) for controlling the first light source (11) and the second light source (12), wherein the control section (4) controls the first light source (11) to the first light source (11). While emitting light in one light emitting mode, the second light source (12) is caused to emit light in a second light emitting mode different from the first light emitting mode overlapping with the light emission of the first light source (11) , and the first light emitting mode is characterized in that the luminance of the second light emission mode increases when the luminance of the second light emission mode decreases .

本発明によれば、第１光源および第２光源が互いに異なる発光態様で重複して発光することで、途中で光源の発光態様が変化する方向指示装置の点灯態様となる。よって、第１光源および第２光源を同じ態様で発光させた単純な点灯と異なり、２つの光源であっても方向指示装置を流動的に点灯させることができる。 According to the present invention, the first light source and the second light source emit light in mutually different light emission modes, thereby providing a lighting mode of the turn indicator device in which the light emission mode of the light source changes midway through. Therefore, unlike simple lighting in which the first light source and the second light source emit light in the same manner, even with two light sources, the turn indicator device can be lighted in a fluid manner.

上記の方向指示装置において、前記第１発光態様および前記第２発光態様は、輝度の立ち上がりが相違していてもよい。 In the direction indicator device described above, the first light emission mode and the second light emission mode may have different rises in brightness.

本発明によれば、第１光源および第２光源それぞれにおいて輝度がピークに達するまでの時間を相違させることができる。これにより、方向指示装置の点灯をより一層流動的に表現できる。 According to the present invention, it is possible to differentiate the time until the luminance reaches the peak in each of the first light source and the second light source. As a result, the lighting of the direction indicating device can be expressed more fluidly.

上記の方向指示装置において、前記第２光源（１２）は、前記第１光源（１１）よりも車幅方向の外方に配置され、前記第２発光態様の輝度の立ち上がりは、前記第１発光態様の輝度の立ち上がりよりも鈍くてもよい。 In the direction indicator device described above, the second light source (12) is arranged further outward in the vehicle width direction than the first light source (11), and the rise of luminance in the second light emission mode is equal to the first light emission. It may be slower than the rising edge of the brightness of the aspect.

本発明によれば、車幅方向外方の光源の輝度がピークに達するまでの時間が長くなるように方向指示装置の点灯が立ち上がる。よって、方向指示装置を車両の進路方向に向けて流れるように点灯させることができる。 According to the present invention, the lighting of the turn signal device rises so that the time until the brightness of the light source on the outside in the vehicle width direction reaches its peak becomes longer. Therefore, the turn indicator device can be illuminated so as to flow toward the course direction of the vehicle.

上記の方向指示装置において、前記第２発光態様の輝度がピークとなるタイミングは、前記第１発光態様の輝度がピークとなるタイミングよりも遅くてもよい。 In the direction indicating device described above, the timing at which the luminance of the second light emission mode reaches its peak may be later than the timing at which the luminance of the first light emission mode reaches its peak.

本発明によれば、輝度がピークに達するまでの時間が短い光源が発光した後に、長い光源が発光する。よって、方向指示装置の点灯をより一層流動的に表現できる。
上記の方向指示装置において、前記第２発光態様の輝度がピークとなるタイミングは、前記第１発光態様の輝度が減少し始めるタイミングよりも遅くてもよい。 According to the present invention, a light source having a shorter time to peak luminance emits light, followed by a longer light source. Therefore, lighting of the direction indicating device can be expressed more fluidly.
In the direction indicator device described above, the timing at which the luminance of the second light emission mode reaches a peak may be later than the timing at which the luminance of the first light emission mode starts to decrease.

本発明の鞍乗り型車両は、上記の方向指示装置（２）を備えることを特徴とする。 A saddle-ride type vehicle according to the present invention is characterized by comprising the direction indicating device (2) described above.

図１は、実施形態の自動二輪車の左側面図である。
図１に示すように、本実施形態は、鞍乗り型車両である自動二輪車１に適用されている。自動二輪車１は、方向指示装置２を備える。方向指示装置２は、自動二輪車１の前部および後部のそれぞれに配置された左右一対の方向指示器３と、それぞれの方向指示器３の点灯を制御する制御部４と、を備える。なお、前後左右の方向指示器３は、それぞれ同様の構成を有するため、以下の方向指示器３の構成に関する説明では、自動二輪車１の前部左側に配置された方向指示器を例に挙げて説明する。 FIG. 1 is a left side view of the motorcycle of the embodiment.

Since the front, rear, left, and right direction indicators 3 have the same configuration, the following explanation of the configuration of the direction indicators 3 will take the direction indicator arranged on the front left side of the motorcycle 1 as an example. explain.

図２は、実施形態に係る方向指示器を示す正面図である。図３は、実施形態に係る方向指示器の内部を示す正面図である。
図２に示すように、方向指示器３は、方向指示のために発光を行う第１光源１１および第２光源１２と、第１光源１１および第２光源１２を収容するハウジング２０と、を備える。ハウジング２０は、第１光源１１および第２光源１２を支持するベース部２１と、第１光源１１および第２光源１２を前方から覆うレンズ２２と、を備える。ベース部２１は、前後方向から見て車幅方向を長手方向とするように形成されている。レンズ２２は、ベース部２１に取り付けられている。レンズ２２は、ベース部２１の形状に倣い、前後方向から見て車幅方向を長手方向とするように形成されている。レンズ２２は、第１光源１１および第２光源１２を覆うウインカレンズとして構成されている。 FIG. 2 is a front view showing the direction indicator according to the embodiment; FIG. 3 is a front view showing the inside of the direction indicator according to the embodiment;
As shown in FIG. 2, the direction indicator 3 includes a first light source 11 and a second light source 12 that emit light for direction indication, and a housing 20 that houses the first light source 11 and the second light source 12. . The housing 20 includes a base portion 21 that supports the first light source 11 and the second light source 12, and a lens 22 that covers the first light source 11 and the second light source 12 from the front. The base portion 21 is formed so that its longitudinal direction is the vehicle width direction when viewed from the front-rear direction. The lens 22 is attached to the base portion 21 . The lens 22 follows the shape of the base portion 21 and is formed so that its longitudinal direction is the vehicle width direction when viewed from the front-rear direction. Lens 22 is configured as a blinker lens that covers first light source 11 and second light source 12 .

第１光源１１および第２光源１２は、例えば発光ダイオードである。第１光源１１および第２光源１２は、レンズ２２の後方で車幅方向に並んで配置されている。第２光源１２は、第１光源１１よりも車幅方向外方に配置されている。第１光源１１および第２光源１２の発光は、制御部４によって制御される。 The first light source 11 and the second light source 12 are, for example, light emitting diodes. The first light source 11 and the second light source 12 are arranged side by side in the vehicle width direction behind the lens 22 . The second light source 12 is arranged further outward in the vehicle width direction than the first light source 11 . Light emission of the first light source 11 and the second light source 12 is controlled by the controller 4 .

制御部４は、第１光源１１および第２光源１２に印加する電圧を制御する。制御部４は、乗員によるウインカスイッチの操作や、図示しない加速度センサや傾斜センサ等の出力等に応じて、第１光源１１および第２光源１２の発光態様を制御する。具体的に、制御部４は、ウインカスイッチが乗員によって操作された場合に、第１光源１１および第２光源１２に電圧を断続的に印加して第１光源１１および第２光源１２を断続的に発光させる。これにより方向指示器３が点滅する。 The control unit 4 controls voltages applied to the first light source 11 and the second light source 12 . The control unit 4 controls the light emitting modes of the first light source 11 and the second light source 12 according to the operation of the blinker switch by the passenger, the output of the acceleration sensor, the tilt sensor, etc. (not shown), and the like. Specifically, when the blinker switch is operated by the passenger, the control unit 4 intermittently applies a voltage to the first light source 11 and the second light source 12 to intermittently turn on the first light source 11 and the second light source 12 . to emit light. As a result, the direction indicator 3 blinks.

図４は、実施形態の第１光源および第２光源における時間と輝度との関係を示すグラフである。図４では、方向指示器３の点滅時の１回の点灯における第１光源１１および第２光源１２それぞれの輝度を表している。
図４に示すように、制御部４は、方向指示器３を点滅させる際、１回の点灯毎に第１光源１１を第１発光態様Ａ１で発光させるとともに、第１光源１１の発光と重複して第２光源１２を第１発光態様Ａ１とは異なる第２発光態様Ａ２で発光させる。第１発光態様Ａ１および第２発光態様Ａ２は、輝度の立ち上がりが相違する。輝度の立ち上がりとは、発光開始時からピーク輝度に至る過程である。第１光源１１および第２光源１２それぞれの輝度を発光開始時からの時間を変数として持つ関数とすると、それらの関数が互いに比例関係になければよい。本実施形態では、第２発光態様Ａ２の輝度の立ち上がりは、第１発光態様Ａ１の輝度の立ち上がりよりも鈍い。つまり、第２光源１２の輝度は、第１光源１１の輝度がピーク輝度に至るまで、第１光源１１の輝度よりも小さい。第２発光態様Ａ２における輝度がピークとなるタイミングＴ２は、第１発光態様Ａ１における輝度がピークとなるタイミングＴ１よりも遅い。 FIG. 4 is a graph showing the relationship between time and luminance for the first light source and the second light source of the embodiment. FIG. 4 shows the luminance of each of the first light source 11 and the second light source 12 when the direction indicator 3 blinks once.
As shown in FIG. 4, when blinking the direction indicator 3, the control unit 4 causes the first light source 11 to emit light in the first light emission mode A1 each time the light is turned on. Then, the second light source 12 is caused to emit light in a second light emission mode A2 different from the first light emission mode A1. The first light emission mode A1 and the second light emission mode A2 differ in the rise of luminance. The rise of luminance is the process from the start of light emission to the peak luminance. Assuming that the luminance of each of the first light source 11 and the second light source 12 is a function having the time from the start of light emission as a variable, those functions need not be proportional to each other. In the present embodiment, the rise in luminance of the second light emission mode A2 is slower than that of the first light emission mode A1. That is, the brightness of the second light source 12 is lower than the brightness of the first light source 11 until the brightness of the first light source 11 reaches the peak brightness. The timing T2 at which the brightness peaks in the second light emission mode A2 is later than the timing T1 at which the brightness peaks in the first light emission mode A1.

第１発光態様Ａ１について詳述する。第１発光態様Ａ１は、立ち上がり期間と、立ち下がり期間と、を含む。立ち上がり期間は、第１光源１１の発光開始時Ｔｓを起点とし、第１光源１１の輝度がピーク輝度Ｌ１に到達するタイミングＴ１までの期間である。立ち上がり期間では、制御部４は、第１光源１１の輝度を最高輝度Ｌ１まで連続的に増加させるように第１光源１１を制御する。制御部４は、立ち上がり期間において、第１光源１１の輝度の勾配（輝度の変化率）の最大値がＧ１となるように第１光源１１を発光させる。立ち下がり期間は、立ち上がり期間に連続する。立ち下がり期間は、第１光源１１の輝度がピーク輝度Ｌ１から減少し始める時点Ｔ１を起点とし、第１光源１１が消灯するタイミングＴｅまでの期間である。立ち下がり期間では、制御部４は、第１光源１１の輝度を連続的に減少させるように第１光源１１を制御する。制御部４は、立ち下がり期間において、第１光源１１の輝度の勾配の最小値がＧ２となるように第１光源１１を発光させる。輝度の勾配Ｇ２の絶対値は、立ち上がり期間の輝度の勾配Ｇ１よりも小さい。立ち下がり期間の時間的長さは、立ち上がり期間の時間的長さよりも大きい。なお、第１発光態様Ａ１において、立ち上がり期間と立ち下がり期間との間に、第１光源１１をピーク輝度Ｌ１で一定の時間発光させる期間を設けてもよい。 The first light emission mode A1 will be described in detail. The first light emission mode A1 includes a rising period and a falling period. The rising period is a period from the light emission start time Ts of the first light source 11 to the timing T1 when the luminance of the first light source 11 reaches the peak luminance L1. During the rising period, the control unit 4 controls the first light source 11 so as to continuously increase the luminance of the first light source 11 to the maximum luminance L1. The control unit 4 causes the first light source 11 to emit light so that the maximum value of the luminance gradient (luminance change rate) of the first light source 11 becomes G1 in the rising period. The falling period is continuous with the rising period. The fall period is a period from time T1 at which the luminance of the first light source 11 starts to decrease from the peak luminance L1 to timing Te at which the first light source 11 is extinguished. During the falling period, the control unit 4 controls the first light source 11 so as to continuously decrease the luminance of the first light source 11 . The control unit 4 causes the first light source 11 to emit light so that the minimum value of the luminance gradient of the first light source 11 is G2 in the fall period. The absolute value of the luminance gradient G2 is smaller than the luminance gradient G1 during the rise period. The temporal length of the falling period is greater than the temporal length of the rising period. In the first light emission mode A1, a period may be provided between the rising period and the falling period during which the first light source 11 emits light at the peak luminance L1 for a certain period of time.

第２発光態様Ａ２について詳述する。第２発光態様Ａ２は、立ち上がり期間と、立ち下がり期間と、を含む。立ち上がり期間は、第２光源１２の発光開始時Ｔｓを起点とし、第２光源１２の輝度がピーク輝度Ｌ２に到達するタイミングＴ２までの期間である。第２光源１２のピーク輝度Ｌ２は、第１光源１１のピーク輝度Ｌ１と等しい。第２光源１２の発光開始時Ｔｓは、第１光源１１の発光開始時Ｔｓと一致する。立ち上がり期間では、制御部４は、第２光源１２の輝度をピーク輝度Ｌ２まで連続的に増加させるように第２光源１２を制御する。制御部４は、立ち上がり期間において、第２光源１２の輝度の勾配の最大値がＧ３となるように第２光源１２を発光させる。輝度の勾配Ｇ３は、第１光源１１の輝度の勾配Ｇ１よりも小さい。これにより、第２発光態様Ａ２の輝度の立ち上がりは、第１発光態様Ａ１の輝度の立ち上がりよりも鈍くなっている。制御部４は、第１光源１１が立ち上がり期間よりも後にある状態（すなわち第１光源１１が立ち下がり期間にある状態）で、第２光源１２の輝度がピーク輝度Ｌ２に到達するように第２光源１２を制御する。これにより、第２発光態様Ａ２における輝度がピークとなるタイミングＴ２は、第１発光態様Ａ１における輝度がピークとなるタイミングＴ１よりも遅くなっている。 The second light emission mode A2 will be described in detail. The second light emission mode A2 includes a rising period and a falling period. The rising period is a period from the light emission start time Ts of the second light source 12 to the timing T2 when the luminance of the second light source 12 reaches the peak luminance L2. The peak luminance L2 of the second light source 12 is equal to the peak luminance L1 of the first light source 11 . The light emission start time Ts of the second light source 12 coincides with the light emission start time Ts of the first light source 11 . During the rising period, the control unit 4 controls the second light source 12 to continuously increase the luminance of the second light source 12 to the peak luminance L2. The control unit 4 causes the second light source 12 to emit light so that the maximum value of the luminance gradient of the second light source 12 is G3 in the rising period. The luminance gradient G3 is smaller than the luminance gradient G1 of the first light source 11 . As a result, the rise in luminance of the second light emission mode A2 is slower than that of the first light emission mode A1. The control unit 4 controls the second light source 11 so that the luminance of the second light source 12 reaches the peak luminance L2 in a state in which the first light source 11 is after the rise period (that is, in a state in which the first light source 11 is in the fall period). Control the light source 12 . As a result, the timing T2 at which the brightness peaks in the second light emission mode A2 is later than the timing T1 at which the brightness peaks in the first light emission mode A1.

立ち下がり期間は、立ち上がり期間に連続する。立ち下がり期間は、第２光源１２の輝度がピーク輝度Ｌ３から減少し始める時点Ｔ２を起点とし、第２光源１２が消灯するまでの期間である。立ち下がり期間では、制御部４は、第２光源１２の輝度を連続的に減少させるように第２光源１２を制御する。制御部４は、立ち下がり期間において、第２光源１２の輝度の勾配の最小値がＧ４となるように第２光源１２を発光させる。輝度の勾配Ｇ４は、第１光源１１の輝度の勾配Ｇ３よりも小さい。第２光源１２の消灯時Ｔｅは、第１光源１１の消灯時Ｔｅと一致する。すなわち、第２発光態様Ａ２の立ち下がり期間の時間的長さは、第１発光態様Ａ１の立ち下がり期間の時間的長さよりも小さい。なお、第２発光態様Ａ２において、立ち上がり期間と立ち下がり期間との間に、第２光源１２をピーク輝度Ｌ２で一定の時間発光させる期間を設けてもよい。 The falling period is continuous with the rising period. The falling period is a period from time T2 when the luminance of the second light source 12 starts to decrease from the peak luminance L3 to when the second light source 12 is extinguished. During the fall period, the controller 4 controls the second light source 12 to continuously decrease the brightness of the second light source 12 . The control unit 4 causes the second light source 12 to emit light so that the minimum value of the luminance gradient of the second light source 12 is G4 in the fall period. The luminance gradient G4 is smaller than the luminance gradient G3 of the first light source 11 . The time Te when the second light source 12 is turned off coincides with the time Te when the first light source 11 is turned off. That is, the temporal length of the fall period of the second light emission mode A2 is shorter than the temporal length of the fall period of the first light emission mode A1. In the second light emission mode A2, a period may be provided between the rising period and the falling period during which the second light source 12 emits light at the peak luminance L2 for a certain period of time.

図５は、実施形態の方向指示器の点滅時における時間と輝度との関係を示すグラフである。
図５に示すように、制御部４は、車体のバンク角、および加速度の大きさのうち少なくともいずれか一方に応じて方向指示器３の点滅の周期を変化させる。具体的に、制御部４は、ウインカスイッチが操作されて方向指示器３が点滅している状態において、車体のバンク角が大きくなるに従い点滅周期が小さくなるように第１光源１１および第２光源１２を制御する。また、制御部４は、ウインカスイッチが操作されて方向指示器３が点滅している状態において、加速度の絶対値が大きくなるに従い点滅周期が小さくなるように第１光源１１および第２光源１２を制御する。制御部４は、第１発光態様Ａ１および第２発光態様Ａ２を変化させず、消灯期間を変化させることにより点滅の周期を変化させる。なお、制御部４は、点滅の周期を変化させるに際し、第１光源１１および第２光源１２の発光時間を短くするように第１発光態様Ａ１および第２発光態様Ａ２を変化させてもよい。 FIG. 5 is a graph showing the relationship between time and luminance when the direction indicator of the embodiment blinks.
As shown in FIG. 5, the control unit 4 changes the blinking cycle of the direction indicator 3 according to at least one of the bank angle of the vehicle body and the magnitude of acceleration. Specifically, in a state where the turn signal switch is operated and the direction indicator 3 is blinking, the control unit 4 controls the first light source 11 and the second light source so that the blinking period becomes shorter as the bank angle of the vehicle body increases. 12 is controlled. Further, the control unit 4 controls the first light source 11 and the second light source 12 so that the blinking period becomes shorter as the absolute value of the acceleration increases in a state where the turn signal switch is operated and the direction indicator 3 blinks. Control. The control unit 4 does not change the first light emission mode A1 and the second light emission mode A2, but changes the extinguishing period to change the blinking cycle. When changing the blinking cycle, the control unit 4 may change the first light emission mode A1 and the second light emission mode A2 so as to shorten the light emission time of the first light source 11 and the second light source 12.

以上に説明したように、本実施形態の方向指示装置２は、第１光源１１および第２光源１２を制御する制御部４を備える。制御部４は、第１光源１１を第１発光態様Ａ１で発光させるとともに、第１光源１１の発光と重複して第２光源１２を第１発光態様Ａ１とは異なる第２発光態様Ａ２で発光させる。この構成によれば、第１光源１１および第２光源１２が互いに異なる発光態様で重複して発光することで、途中で光源の発光態様が変化する方向指示装置の点灯態様となる。よって、第１光源１１および第２光源１２を同じ態様で発光させた単純な点灯と異なり、２つの光源であっても方向指示器３を流動的に点灯させることができる。 As described above, the direction indicating device 2 of this embodiment includes the control section 4 that controls the first light source 11 and the second light source 12 . The control unit 4 causes the first light source 11 to emit light in a first light emission mode A1, and causes the second light source 12 to emit light in a second light emission mode A2 different from the first light emission mode A1 in overlap with the light emission of the first light source 11. Let According to this configuration, the first light source 11 and the second light source 12 overlap and emit light in different light emission modes, so that the lighting mode of the direction indicating device in which the light emission modes of the light sources change midway is obtained. Therefore, unlike simple lighting in which the first light source 11 and the second light source 12 emit light in the same manner, even with two light sources, the direction indicator 3 can be lighted in a fluid manner.

また、流動的な点灯が２つの光源によって実現されるので、方向指示器３の車幅方向の寸法が上下方向の寸法に対して大きくなりすぎることを抑制できる。よって自動二輪車１におけるレイアウト上の制約を受けにくい方向指示装置２とすることができる。 In addition, since fluid lighting is realized by the two light sources, it is possible to prevent the size of the direction indicator 3 in the vehicle width direction from becoming too large relative to the size in the vertical direction. Therefore, it is possible to provide the direction indicator device 2 that is less likely to be restricted by the layout of the motorcycle 1 .

また、第１発光態様Ａ１および第２発光態様Ａ２は、輝度の立ち上がりが相違する。この構成によれば、第１光源１１および第２光源１２それぞれにおいて輝度がピークに達するまでの時間を相違させることができる。これにより、方向指示器３をより一層流動的に表現できる。 Also, the first light emission mode A1 and the second light emission mode A2 differ in the rise of luminance. According to this configuration, the time required for the luminance to reach the peak can be differentiated between the first light source 11 and the second light source 12 . Thereby, the direction indicator 3 can be expressed more fluidly.

また、第１光源１１および第２光源１２それぞれの輝度が連続的に変化しているので、方向指示器３を最も明るい部位が滑らかに移動するように点灯させることができる。 In addition, since the luminance of each of the first light source 11 and the second light source 12 is continuously changed, the direction indicator 3 can be lit so that the brightest part moves smoothly.

また、第２光源１２は、第１光源１１よりも車幅方向の外方に配置されている。第２発光態様Ａ２の輝度の立ち上がりは、第１発光態様Ａ１の輝度の立ち上がりよりも鈍い。この構成によれば、車幅方向外方の光源の輝度がピークに達するまでの時間が長くなるように方向指示器３の点灯が立ち上がる。よって、方向指示器３を車両の進路方向に向けて流れるように点灯させることができる。 Further, the second light source 12 is arranged outside the first light source 11 in the vehicle width direction. The rise in brightness of the second light emission mode A2 is slower than the rise in brightness of the first light emission mode A1. According to this configuration, the lighting of the direction indicator 3 rises so that the time until the brightness of the light source on the outside in the vehicle width direction reaches its peak becomes longer. Therefore, the direction indicator 3 can be turned on so as to flow toward the course direction of the vehicle.

また、第２発光態様Ａ２の輝度がピークとなるタイミングＴ２は、第１発光態様Ａ１の輝度がピークとなるタイミングＴ１よりも遅い。この構成では、輝度がピークに達するまでの時間が短い光源が発光した後に、輝度がピークに達するまでの時間が長い光源が発光する。よって、方向指示器３の点灯をより一層流動的に表現できる。 Further, the timing T2 at which the brightness of the second light emission mode A2 peaks is later than the timing T1 at which the brightness of the first light emission mode A1 peaks. In this configuration, the light source whose brightness peaks in a short time emits light, and then the light source whose brightness peaks in a long time emits light. Therefore, lighting of the direction indicator 3 can be expressed more fluidly.

また、自動二輪車１は、上述した方向指示装置２を備える。この構成によれば、流動的に点灯する方向指示装置２を備えた自動二輪車１を提供できる。 The motorcycle 1 also includes the direction indicating device 2 described above. According to this configuration, it is possible to provide the motorcycle 1 equipped with the direction indicator device 2 that lights up in a fluid manner.

また、制御部４は、車体のバンク角に応じて方向指示器３の点滅の周期を変化させる。このため、急カーブ走行などの車両の挙動変化が大きい場合に、車両の様子を方向指示器３によって表現できる。 Further, the control unit 4 changes the blinking cycle of the direction indicator 3 according to the bank angle of the vehicle body. Therefore, when the behavior of the vehicle changes greatly, such as driving on a sharp curve, the direction indicator 3 can express the state of the vehicle.

また、制御部４は、加速度の大きさに応じて方向指示器３の点滅の周期を変化させる。このため、急ブレーキや急加速などの車両の挙動変化が大きい場合に、車両の様子を方向指示器３によって表現できる。 Further, the control unit 4 changes the blinking period of the direction indicator 3 according to the magnitude of the acceleration. Therefore, when the behavior of the vehicle changes greatly, such as sudden braking or sudden acceleration, the direction indicator 3 can express the state of the vehicle.

なお、本発明は、図面を参照して説明した上述の実施形態に限定されるものではなく、その技術的範囲において様々な変形例が考えられる。

また、上記実施形態の制御部４は、車体のバンク角や加速度等の挙動の変化に合わせて、第１光源１１の輝度がピークとなるタイミングＴ１、および第２光源１２の輝度がピークとなるタイミングＴ２のうち少なくともいずれか一方を変化させてもよい。 In addition, the control unit 4 of the above-described embodiment adjusts the timing T1 when the luminance of the first light source 11 reaches its peak and the luminance of the second light source 12 reaches its peak according to changes in behavior such as the bank angle and acceleration of the vehicle body. At least one of the timings T2 may be changed.

また、上記実施形態では、制御部４は、ウインカスイッチが操作されて方向指示器３が点滅している状態において、方向指示器３の点滅の周期を変化させるように構成されている。しかしながら、制御部は、例えば急ブレーキなどによって車両の挙動が所定の閾値を超えた場合に方向指示器３を点滅させ、かつ挙動変化の大きさに応じて方向指示器３の点滅の周期を変化させてもよい。 Further, in the above-described embodiment, the control unit 4 is configured to change the blinking cycle of the direction indicator 3 in a state where the blinker switch is operated and the direction indicator 3 is blinking. However, the control unit blinks the direction indicator 3 when the behavior of the vehicle exceeds a predetermined threshold due to, for example, sudden braking, and changes the blinking period of the direction indicator 3 according to the magnitude of the change in behavior.
