　本発明の上記（１）に記載の鞍乗型車両によれば、エンジンを制御する第一制御ユニットと、第一制御ユニットと別個に設けられ、発電機を制御する第二制御ユニットと、を備えることで、以下の効果を奏する。第一制御ユニットと第二制御ユニットとが別体であることで、エンジンと第一制御ユニットとを接続するハーネス（以下「エンジン用ハーネス」ともいう。）、および発電機と第二制御ユニットとを接続するハーネス（以下「発電機用ハーネス」ともいう。）の各ハーネス長を考慮した最適位置に各制御ユニットを配置することができる。加えて、各制御ユニットのサイズを単一の制御ユニットよりも小さくすることができ、各制御ユニットを車両のデッドスペースに配置しやすい。加えて、各制御ユニットを独立して設計することができるため、開発コストを可及的に低減することができる。加えて、リアサスペンションのバネの下部に設けられた部材に接続されたエアクリーナを備え、第二制御ユニットは、エアクリーナの前後方向に沿うように配置されていることで、以下の効果を奏する。第二制御ユニットが外気の流れる位置に配置されるため、第二制御ユニットを効率よく冷却することができ、エンジンによる熱の影響を受けにくい。加えて、第二制御ユニットがエアクリーナの幅方向（左右方向）に沿うように配置された場合と比較して、吸気や外気の空気の流れを阻害しにくい。加えて、バッテリがエンジンの前方（例えばフロア下）に設けられた場合には、バッテリと第二制御ユニットとを接続するハーネスを短くしやすいため、当該ハーネスの振動を低減することができる。したがって、別体の制御ユニットを備えた鞍乗型車両において、各制御ユニットの要求性能を満たしながら効率よく配置・配索することできる。 According to the saddle-mounted vehicle according to the above (1) of the present invention, the first control unit that controls the engine and the second control unit that is separately provided from the first control unit and controls the generator. By preparing, the following effects are achieved. Since the first control unit and the second control unit are separate bodies, a harness for connecting the engine and the first control unit (hereinafter, also referred to as "engine harness"), and a generator and the second control unit. Each control unit can be arranged at an optimum position in consideration of each harness length of the harness (hereinafter, also referred to as “generator harness”) to connect the two. In addition, the size of each control unit can be made smaller than that of a single control unit, making it easier to place each control unit in the dead space of the vehicle. In addition, since each control unit can be designed independently, the development cost can be reduced as much as possible. In addition, an air cleaner connected to a member provided under the spring of the rear suspension is provided, and the second control unit is arranged along the front-rear direction of the air cleaner to achieve the following effects. Since the second control unit is arranged at a position where the outside air flows, the second control unit can be cooled efficiently and is not easily affected by the heat of the engine. In addition, as compared with the case where the second control unit is arranged along the width direction (horizontal direction) of the air cleaner, it is less likely to obstruct the flow of intake air and outside air. In addition, when the battery is provided in front of the engine (for example, under the floor), the harness connecting the battery and the second control unit can be easily shortened, so that the vibration of the harness can be reduced. Therefore, in a saddle-mounted vehicle equipped with a separate control unit, it is possible to efficiently arrange and allocate the vehicle while satisfying the required performance of each control unit.
　本発明の上記（２）に記載の鞍乗型車両によれば、エアクリーナは、外気が導入される第一ケースと、外気を濾過するためのフィルタと、フィルタによって濾過された空気が導入される第二ケースと、を備え、第一ケースは、第二制御ユニットを設置可能に開口する開口部を有し、第二制御ユニットは、第一ケースの開口部に設けられていることで、以下の効果を奏する。第二制御ユニットがダーティサイドに設けられるため、第二制御ユニットと開口部との間に隙間ができても第一ケースのシール性を気にしなくてよい。 According to the saddle-mounted vehicle described in (2) above of the present invention, the air cleaner is introduced with a first case in which outside air is introduced, a filter for filtering the outside air, and air filtered by the filter. The second case is provided, the first case has an opening for installing the second control unit, and the second control unit is provided in the opening of the first case. Play the effect of. Since the second control unit is provided on the dirty side, even if there is a gap between the second control unit and the opening, it is not necessary to worry about the sealing property of the first case.
　本発明の上記（３）に記載の鞍乗型車両によれば、エアクリーナは、外気が導入される第一ケースと、外気を濾過するためのフィルタと、第一ケースよりも車幅方向内側に配置され、フィルタによって濾過された空気が導入される第二ケースと、を備え、第二ケースは、第二制御ユニットを設置可能に開口する開口部を有し、第二制御ユニットは、第二ケースの開口部に設けられていることで、以下の効果を奏する。第二制御ユニットが第一ケースよりも車幅方向内側においてクリーンサイドに設けられるため、第一ケースによって第二制御ユニットを外的要因から保護することができる。例えば、車幅方向外方からエアクリーナへ飛び石等の衝撃があっても、第二制御ユニットは前記衝撃によるダメージを受けにくい。 According to the saddle-mounted vehicle described in (3) above of the present invention, the air cleaner has a first case in which outside air is introduced, a filter for filtering the outside air, and an air cleaner inside the vehicle width direction from the first case. It comprises a second case, which is arranged and introduced with air filtered by a filter, the second case has an opening that allows the second control unit to be installed, and the second control unit is the second. By being provided in the opening of the case, the following effects are obtained. Since the second control unit is provided on the clean side inside the vehicle width direction with respect to the first case, the first case can protect the second control unit from external factors. For example, even if an impact such as a stepping stone hits the air cleaner from the outside in the vehicle width direction, the second control unit is less likely to be damaged by the impact.
　本発明の上記（４）に記載の鞍乗型車両によれば、エアクリーナは、車両の車幅方向外側部に配置され、第二制御ユニットは、エアクリーナの車幅方向内側面に配置されていることで、以下の効果を奏する。エアクリーナの車幅方向外側部によって第二制御ユニットを外的要因から保護することができる。例えば、車幅方向外方からエアクリーナへ飛び石等の衝撃があっても、第二制御ユニットは前記衝撃によるダメージを受けにくい。 According to the saddle-mounted vehicle according to the above (4) of the present invention, the air cleaner is arranged on the outer side of the vehicle in the vehicle width direction, and the second control unit is arranged on the inner side surface of the air cleaner in the vehicle width direction. As a result, the following effects are achieved. The outer portion of the air cleaner in the vehicle width direction can protect the second control unit from external factors. For example, even if an impact such as a stepping stone hits the air cleaner from the outside in the vehicle width direction, the second control unit is less likely to be damaged by the impact.
　本発明の上記（５）に記載の鞍乗型車両によれば、エアクリーナと上下方向で対向する伝動ケースを更に備え、第二制御ユニットは、エアクリーナと伝動ケースとの間に配置されていることで、以下の効果を奏する。エアクリーナと伝動ケースとの間のデッドスペースを第二制御ユニットの配置空間として有効活用しつつ、第二制御ユニットを冷却することができる。 According to the saddle-mounted vehicle according to the above (5) of the present invention, a transmission case that faces the air cleaner in the vertical direction is further provided, and the second control unit is arranged between the air cleaner and the transmission case. The following effects are achieved. The second control unit can be cooled while effectively utilizing the dead space between the air cleaner and the transmission case as the arrangement space for the second control unit.
　本発明の上記（６）に記載の鞍乗型車両によれば、第一制御ユニットは、第二制御ユニットとは異なる位置でエアクリーナの前後方向に沿うように配置されていることで、以下の効果を奏する。第一制御ユニットが外気の流れる位置に配置されるため、第一制御ユニットを効率よく冷却することができ、エンジンによる熱の影響を受けにくい。加えて、第一制御ユニットがエアクリーナの幅方向（左右方向）に沿うように配置された場合と比較して、吸気や外気の空気の流れを阻害しにくい。加えて、第一制御ユニットが第二制御ユニットの近傍に配置されるため、第一制御ユニットと第二制御ユニットとを接続するハーネスを短くすることができ、ノイズを受けにくい。加えて、第一制御ユニットと第二制御ユニットとを接続するハーネスを短くすることにより、当該ハーネスの振動を低減することができる。したがって、別体の制御ユニットを備えた鞍乗型車両において、各制御ユニットの要求性能を満たしながらより効果的に配置・配索することできる。 According to the saddle-mounted vehicle according to the above (6) of the present invention, the first control unit is arranged along the front-rear direction of the air cleaner at a position different from that of the second control unit. It works. Since the first control unit is arranged at a position where the outside air flows, the first control unit can be cooled efficiently and is not easily affected by the heat of the engine. In addition, as compared with the case where the first control unit is arranged along the width direction (horizontal direction) of the air cleaner, it is less likely to obstruct the flow of intake air and outside air. In addition, since the first control unit is arranged in the vicinity of the second control unit, the harness connecting the first control unit and the second control unit can be shortened, and noise is less likely to be received. In addition, by shortening the harness connecting the first control unit and the second control unit, the vibration of the harness can be reduced. Therefore, in a saddle-mounted vehicle equipped with a separate control unit, it is possible to more effectively arrange and allocate the vehicle while satisfying the required performance of each control unit.

According to this configuration, the FI-ECU 51 that controls the engine 11 and the ACG-ECU 52 that is provided separately from the FI-ECU 51 and controls the generator 13 have the following effects. Since the FI-ECU 51 and the ACG-ECU 52 are separate bodies, the control units 51 and 52 can be arranged at the optimum positions in consideration of the harness lengths of the engine harness and the generator harness. In addition, the size of each control unit 51, 52 can be made smaller than that of a single control unit, and each control unit 51, 52 can be easily arranged in the dead space of the vehicle. In addition, since the control units 51 and 52 can be designed independently, the development cost can be reduced as much as possible. In addition, the ACG-ECU 52 is provided with an air cleaner 40 connected to a member provided below the spring of the rear suspension 27, and the ACG-ECU 52 is arranged along the front-rear direction of the air cleaner 40 to achieve the following effects. .. Since the ACG-ECU 52 is arranged at a position where the outside air flows, the ACG-ECU 52 can be efficiently cooled and is not easily affected by the heat generated by the engine 11. In addition, as compared with the case where the ACG-ECU 52 is arranged along the width direction (left-right direction) of the air cleaner 40, it is less likely to obstruct the flow of intake air and outside air. In addition, when the battery 53 is provided in front of the engine 11 (for example, under the floor), the harness (third harness 63) connecting the battery 53 and the ACG-ECU 52 can be easily shortened, so that the third harness 63 Vibration can be reduced. Therefore, in the motorcycle 1 provided with the separate control units 51 and 52, the motorcycles 1 can be efficiently arranged and arranged while satisfying the required performance of the respective control units 51 and 52.

The first case 91 has a dirty side opening 91a that allows the ACG-ECU 52 to be installed, and the ACG-ECU 52 is provided in the dirty side opening 91a of the first case 91, thereby achieving the following effects. .. Since the ACG-ECU 52 is provided on the dirty side, it is not necessary to worry about the sealing property of the first case 91 even if a gap is formed between the ACG-ECU 52 and the dirty side opening 91a.
　上記実施形態では、ＦＩ－ＥＣＵ５１は、ＡＣＧ－ＥＣＵ５２とは異なる位置でエアクリーナ４０の前後方向に沿うように配置されていることで、以下の効果を奏する。ＦＩ－ＥＣＵ５１が外気の流れる位置に配置されるため、ＦＩ－ＥＣＵ５１を効率よく冷却することができ、エンジン１１による熱の影響を受けにくい。加えて、ＦＩ－ＥＣＵ５１がエアクリーナ４０の幅方向（左右方向）に沿うように配置された場合と比較して、吸気や外気の空気の流れを阻害しにくい。加えて、ＦＩ－ＥＣＵ５１がＡＣＧ－ＥＣＵ５２の近傍に配置されるため、ＦＩ－ＥＣＵ５１とＡＣＧ－ＥＣＵ５２とを接続するハーネス（第一ハーネス６１）を短くすることができ、ノイズを受けにくい。加えて、ＦＩ－ＥＣＵ５１とＡＣＧ－ＥＣＵ５２とを接続する第一ハーネス６１を短くすることにより、第一ハーネス６１の振動を低減することができる。したがって、別体の制御ユニット５１，５２を備えた自動二輪車１において、各制御ユニット５１，５２の要求性能を満たしながらより効果的に配置・配索することができる。 In the above embodiment, the FI-ECU 51 is arranged at a position different from that of the ACG-ECU 52 along the front-rear direction of the air cleaner 40, thereby achieving the following effects. Since the FI-ECU 51 is arranged at a position where the outside air flows, the FI-ECU 51 can be efficiently cooled and is not easily affected by the heat generated by the engine 11. In addition, as compared with the case where the FI-ECU 51 is arranged along the width direction (left-right direction) of the air cleaner 40, it is less likely to obstruct the flow of intake air and outside air. In addition, since the FI-ECU 51 is arranged in the vicinity of the ACG-ECU 52, the harness (first harness 61) connecting the FI-ECU 51 and the ACG-ECU 52 can be shortened, and noise is less likely to be received. In addition, by shortening the first harness 61 that connects the FI-ECU 51 and the ACG-ECU 52, the vibration of the first harness 61 can be reduced. Therefore, in the motorcycle 1 provided with the separate control units 51 and 52, it is possible to arrange and allocate the motorcycle more effectively while satisfying the required performance of each of the control units 51 and 52.
　上記実施形態では、ＦＩ－ＥＣＵ５１は、第二ケース９２のクリーン側開口９２ａに設けられていることで、以下の効果を奏する。ＦＩ－ＥＣＵ５１が第一ケース９１よりも車幅方向内側においてクリーンサイドに設けられるため、第一ケース９１によってＦＩ－ＥＣＵ５１を外的要因から保護することができる。例えば、車幅方向外方からエアクリーナ４０へ飛び石等の衝撃があっても、ＦＩ－ＥＣＵ５１は前記衝撃によるダメージを受けにくい。 In the above embodiment, the FI-ECU 51 is provided in the clean side opening 92a of the second case 92, thereby achieving the following effects. Since the FI-ECU 51 is provided on the clean side inside the first case 91 in the vehicle width direction, the FI-ECU 51 can be protected from external factors by the first case 91. For example, even if an impact such as a stepping stone is applied to the air cleaner 40 from the outside in the vehicle width direction, the FI-ECU 51 is less likely to be damaged by the impact.
＜変形例＞
　以下、実施形態に変形例について説明する。以下の変形例において、上記実施形態と同様の構成については同一の符号を付し、その詳細説明は省略する。
　上記実施形態では、ＡＣＧ－ＥＣＵ５２が第一ケース９１のダーティ側開口９１ａに設けられている例を挙げて説明したが、これに限らない。 <Modification example>
Hereinafter, a modified example will be described in the embodiment. In the following modification, the same components as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.
In the above embodiment, the example in which the ACG-ECU 52 is provided in the dirty side opening 91a of the first case 91 has been described, but the present invention is not limited to this.
＜第一変形例＞
　図５は、実施形態の第一変形例に係るＥＣＵ配置構造を示す、図３に相当する図である。例えば、図５に示すように、ＡＣＧ－ＥＣＵ５２は、第二ケース９２のクリーン側開口９２ａに設けられていてもよい。 <First modification>
FIG. 5 is a diagram corresponding to FIG. 3 showing an ECU arrangement structure according to the first modification of the embodiment. For example, as shown in FIG. 5, the ACG-ECU 52 may be provided in the clean side opening 92a of the second case 92.
　クリーン側開口９２ａは、ＡＣＧ－ＥＣＵ５２を設置可能に開口している。第一ケース９１は、ＡＣＧ－ＥＣＵ５２を設置可能に開口する開口部（ダーティ側開口９１ａ）を有しない。ＡＣＧ－ＥＣＵ５２の厚み方向中央部は、第二ケース９２の車幅方向内側面に沿うように配置されている。例えば、ＡＣＧ－ＥＣＵ５２は、クリーン側開口９２ａに圧入固定されている。例えば、ＡＣＧ－ＥＣＵ５２の端子部は、第二ケース９２内に配置されている。
　ＦＩ－ＥＣＵ５１は、リアサスペンション２７のバネの上部（以下「バネ上」ともいう。）に設けられた部材に配置されている。例えば、リアサスペンション２７のバネの上部に設けられた部材は、リアサスペンション２７の上端を支持する支持部材（車体フレーム２０）である。例えば、ＦＩ－ＥＣＵ５１は、車体フレーム２０に取り付けられている。 The clean side opening 92a is open so that the ACG-ECU 52 can be installed. The first case 91 does not have an opening (dirty side opening 91a) that allows the ACG-ECU 52 to be installed. The central portion of the ACG-ECU 52 in the thickness direction is arranged along the inner side surface of the second case 92 in the vehicle width direction. For example, the ACG-ECU 52 is press-fitted and fixed to the clean side opening 92a. For example, the terminal portion of the ACG-ECU 52 is arranged in the second case 92.
The FI-ECU 51 is arranged on a member provided on the upper part of the spring of the rear suspension 27 (hereinafter, also referred to as “spring”). For example, the member provided above the spring of the rear suspension 27 is a support member (body frame 20) that supports the upper end of the rear suspension 27. For example, the FI-ECU 51 is attached to the vehicle body frame 20.
　本変形例では、ＡＣＧ－ＥＣＵ５２は、第二ケース９２のクリーン側開口９２ａに設けられていることで、以下の効果を奏する。ＡＣＧ－ＥＣＵ５２が第一ケース９１よりも車幅方向内側においてクリーンサイドに設けられるため、第一ケース９１によってＡＣＧ－ＥＣＵ５２を外的要因から保護することができる。例えば、車幅方向外方からエアクリーナ４０へ飛び石等の衝撃があっても、ＡＣＧ－ＥＣＵ５２は前記衝撃によるダメージを受けにくい。 In this modification, the ACG-ECU 52 is provided in the clean side opening 92a of the second case 92, so that the following effects are obtained. Since the ACG-ECU 52 is provided on the clean side inside the first case 91 in the vehicle width direction, the ACG-ECU 52 can be protected from external factors by the first case 91. For example, even if an impact such as a stepping stone is applied to the air cleaner 40 from the outside in the vehicle width direction, the ACG-ECU 52 is less likely to be damaged by the impact.
　本変形例では、ＦＩ－ＥＣＵ５１は、リアサスペンション２７のバネ上に配置されていることで、以下の効果を奏する。ＦＩ－ＥＣＵ５１およびＡＣＧ－ＥＣＵ５２のそれぞれがリアサスペンション２７のバネ下に配置された場合と比較して、リアサスペンション２７のバネ下の重量を軽量化することができる。したがって、リアサスペンション２７の作動性を向上し、路面追従性および悪路走破性を向上することができる。 In this modification, the FI-ECU 51 is arranged on the spring of the rear suspension 27, so that the following effects are obtained. The unsprung weight of the rear suspension 27 can be reduced as compared with the case where each of the FI-ECU 51 and the ACG-ECU 52 is arranged under the spring of the rear suspension 27. Therefore, the operability of the rear suspension 27 can be improved, and the road surface followability and the rough road running performance can be improved.
＜第二変形例＞
　図６は、実施形態の第二変形例に係るＥＣＵ配置構造を示す、図３に相当する図である。例えば、図６に示すように、ＡＣＧ－ＥＣＵ５２は、エアクリーナ４０の車幅方向内側面４０ａに配置されていてもよい。 <Second modification>

　第一ケース９１および第二ケース９２のそれぞれは、ＡＣＧ－ＥＣＵ５２を設置可能に開口する開口部（ダーティ側開口９１ａおよびクリーン側開口９２ａ）を有しない。ＡＣＧ－ＥＣＵ５２の車幅方向外側面は、第二ケース９２の車幅方向内側面４０ａに沿うように配置されている。例えば、ＡＣＧ－ＥＣＵ５２は、ボルト等の締結部材（不図示）によって第二ケース９２に締結固定されている。
　ＦＩ－ＥＣＵ５１は、リアサスペンション２７のバネ上に配置されている。例えば、ＦＩ－ＥＣＵ５１は、車体フレーム２０に取り付けられている。 Each of the first case 91 and the second case 92 does not have an opening (dirty side opening 91a and clean side opening 92a) in which the ACG-ECU 52 can be installed. The outer surface of the ACG-ECU 52 in the vehicle width direction is arranged along the inner surface 40a of the second case 92 in the vehicle width direction. For example, the ACG-ECU 52 is fastened and fixed to the second case 92 by a fastening member (not shown) such as a bolt.
The FI-ECU 51 is arranged on the spring of the rear suspension 27. For example, the FI-ECU 51 is attached to the vehicle body frame 20.
　本変形例では、ＡＣＧ－ＥＣＵ５２は、エアクリーナ４０の車幅方向内側面４０ａに配置されていることで、以下の効果を奏する。エアクリーナ４０の車幅方向外側部によってＡＣＧ－ＥＣＵ５２を外的要因から保護することができる。例えば、車幅方向外方からエアクリーナ４０へ飛び石等の衝撃があっても、ＡＣＧ－ＥＣＵ５２は前記衝撃によるダメージを受けにくい。 In this modification, the ACG-ECU 52 is arranged on the inner side surface 40a of the air cleaner 40 in the vehicle width direction to obtain the following effects. The outer portion of the air cleaner 40 in the vehicle width direction can protect the ACG-ECU 52 from external factors. For example, even if an impact such as a stepping stone is applied to the air cleaner 40 from the outside in the vehicle width direction, the ACG-ECU 52 is less likely to be damaged by the impact.
＜第三変形例＞
図７は、実施形態の第三変形例に係るＥＣＵ配置構造の左側面図である。例えば、図７に示すように、ＡＣＧ－ＥＣＵ５２は、エアクリーナ４０と伝動ケース３９との間に配置されていてもよい。 <Third modification example>
FIG. 7 is a left side view of the ECU arrangement structure according to the third modification of the embodiment. For example, as shown in FIG. 7, the ACG-ECU 52 may be arranged between the air cleaner 40 and the transmission case 39.
　第一ケース９１および第二ケース９２のそれぞれは、ＡＣＧ－ＥＣＵ５２を設置可能に開口する開口部（ダーティ側開口９１ａおよびクリーン側開口９２ａ）を有しない。ＡＣＧ－ＥＣＵ５２の上面は、エアクリーナ４０の下面に沿うように配置されている。ＡＣＧ－ＥＣＵ５２の下面は、伝動ケース３９の上面に沿うように配置されている。ＡＣＧ－ＥＣＵ５２は、エアクリーナ４０および伝動ケース３９が対向する領域内（前後方向間内かつ車幅方向間内）に配置されている。ＡＣＧ－ＥＣＵ５２の車幅方向外端は、エアクリーナ４０および伝動ケース３９のそれぞれの車幅方向外側面よりも車幅方向内側に配置されている。例えば、ＡＣＧ－ＥＣＵ５２は、ボルト等の締結部材（不図示）によってエアクリーナ４０に締結固定されている。
　ＦＩ－ＥＣＵ５１は、リアサスペンション２７のバネ上に配置されている。例えば、ＦＩ－ＥＣＵ５１は、車体フレーム２０に取り付けられている。 Each of the first case 91 and the second case 92 does not have an opening (dirty side opening 91a and clean side opening 92a) in which the ACG-ECU 52 can be installed. The upper surface of the ACG-ECU 52 is arranged along the lower surface of the air cleaner 40. The lower surface of the ACG-ECU 52 is arranged along the upper surface of the transmission case 39.
