FI-ECU61 and ACG-ECU62 are arranged so that they do not overlap each other when viewed from above, but are staggered from each other in the width direction of the vehicle body. In the present embodiment, FI-ECU 61 is arranged on the left side of ACG-ECU 62 . Specifically, FI-ECU 61 is disposed as a whole so that the center of gravity of ACG-ECU 62 is located on the left side.

Since the parts are divided, the increase in size and heat generation of the control unit 60 as a whole can be more reliably suppressed.

Moreover, FI-ECU61 and ACG-ECU62 are arrange|positioned so that they may not overlap when viewed from the side. According to this configuration, the weight balance in the front-rear direction and the weight balance in the up-down direction can be ensured by the FI-ECU 61 and ACG-ECU 62 arranged in a dispersed manner.

The coupler 65 of the FI-ECU 61 protrudes in a direction inclined forward with respect to the vertical direction. According to this structure, the coupler 65 of the FI-ECU 61 faces the control object of the FI-ECU 61, that is, the side of the engine 40 in the up and down direction, and therefore, the connection part between the FI-ECU 61 and the engine 40 in the wire group 70 can be shortened. length. Therefore, the material cost of the wire group 70 can be reduced.

Since the ACG-ECU 62 is covered from the outside in the vehicle width direction by the rear cover portion 53 of the vehicle body cover 6 , the ACG-ECU 62 can be protected.

FI-ECU61 is adjacent to air cleaner 46. According to such a configuration, the running wind can be more easily concentrated around the air cleaner 46, so that the FI-ECU 61 can be air-cooled efficiently.

The FI-ECU 61 is arranged so as to overlap with the mounting portion 48 of the air cleaner 46 when viewed from the side.

On the other hand, the fourth embodiment differs from the second embodiment in that FI-ECU 61 and ACG-ECU 62 are arranged so as to be overlapped when viewed from the side. In addition, the structure other than the structure demonstrated below is the same as 2nd Embodiment.

The FI-ECU 61 is disposed further behind the engine 40 which is its control object. And the FI-ECU 61 is fixed to the rear frame 24 on the left side. The FI-ECU 61 is arranged at a position covered by the rear cover portion 53 of the vehicle body cover 6 from outside in the vehicle width direction. The FI-ECU 61 is arranged above the centers of gravity G of the vehicles. The FI-ECU61 is arranged at the top of the mufflers 8.

By arranging FI-ECU 61 as described above, FI-ECU 61 and ACG-ECU 62 in this embodiment have the following positional relationship. FI-ECU61 and ACG-ECU62 are arranged on the opposite sides of the vehicle body width center (not shown) as the center. The FI-ECU61 and ACG-ECU62 are arranged so as to be shifted from each other in the vehicle width direction without overlapping when viewed from above. In this embodiment, FI-ECU61 is arranged on the left side of ACG-ECU62. FI-ECU61 and ACG-ECU62 are arranged so as to overlap each other when viewed from the side.

According to the two-wheeled vehicle 301 of the fourth embodiment described above, in addition to the same effects as those of the second embodiment, the following effects can be achieved.

FI-ECU61 and ACG-ECU62 are arranged to overlap each other when viewed from the side. According to such a structure, the wire arrangement|positioning of the part from the connection part with FI-ECU61 to the connection part with ACG-ECU62 among the wire group 70 becomes relatively easy.

Both of the FI-ECU61 and the ACG-ECU62 are disposed above the mufflers 8 . According to this structure, the mass is distributed on the upper part of the vehicle, so that the moment of inertia of the vehicle in the left and right roll directions becomes large, and thus the stability during driving can be improved.

In addition, this invention is not limited to the said embodiment demonstrated with drawing and drawing, Various modification examples are conceivable within the technical range. For example: In the above-mentioned embodiment, the example of applying the present invention to a scooter-type straddle-type vehicle is shown, but the present invention can be applied to all straddle vehicles in which the rider's feet straddle the vehicle body. riding vehicle. In other words, for example, the structures of the above-described embodiments may be combined with at least one of a two-wheeled motorcycle or a three-wheeled motorcycle that does not have a footrest and a unit swing type rear suspension.

In addition, the arrangement form of FI-ECU 61 and ACG-ECU 62 is not limited to the arrangement form in the above-mentioned embodiment, as long as FI-ECU 61 and ACG-ECU 62 are arranged with a shift in the vehicle width direction. For example, in each embodiment, FI-ECU61 and ACG-ECU62 may be mutually replaced and arrange|positioned.

In addition, without departing from the gist of the present invention, the constituent elements in the above-described embodiments may be appropriately replaced with known constituent elements, and the above-described embodiments and modifications may be appropriately combined. .
