5 is a half cross-sectional view of the rear portion of the two-wheeled locomotive according to the first embodiment viewed from the front. In addition, FIG. 5 shows the state which removed the vehicle body cover 6. As shown in FIG. As shown in FIG. 5 , the FI-ECU 61 and the ACG-ECU 62 are arranged on the same side (right side) with respect to the vehicle body width center C of the vehicle. Both the FI-ECU 61 and the ACG-ECU 62 are arranged on the outer side in the vehicle body width direction than the rear frame 24 on the right side. The FI-ECU 61 and the ACG-ECU 62 are arranged so as to overlap each other in a frontal line of sight viewed from the front.

The FI-ECU 61 and the ACG-ECU 62 among the plurality of control units 60 are arranged so as to be shifted from each other in the front-rear direction. According to this configuration, compared to the case where the engine and the generator are controlled by a single control unit, both the FI-ECU 61 and the ACG-ECU 62 can be both reduced in size, and heat generation can be suppressed. In this way, the increase in size and heat generation of the control unit 60 as a whole can be suppressed.

In addition to the above-described effects, by reducing the size of the FI-ECU 61 and the ACG-ECU 62 , restrictions on the arrangement of the FI-ECU 61 and the ACG-ECU 62 can be reduced. Therefore, the FI-ECU 61 and the ACG-ECU 62 can be arranged to be shifted in the front-rear direction.

Furthermore, by arranging the FI-ECU 61 and the ACG-ECU 62 among the plurality of control units 60 in the above-described manner, it is possible to control the fuel injection and ignition control parts and the generator 43 that are particularly required to have information processing capabilities. Since the part is divided, the increase in size and heat generation of the control unit 60 as a whole can be suppressed more reliably.

Moreover, FI-ECU61 and ACG-ECU62 are arrange|positioned so that it may overlap with each other when viewed from the front. According to this structure, the wiring arrangement of the part from the connection part with the FI-ECU 61 to the connection part with the ACG-ECU 62 in the wire group 70 can be made easier.

With this configuration, the first coupler 67 of the ACG-ECU 62 is directed to the side of the generator 43 , which is the control object of the ACG-ECU 62 in the vertical direction, so that the ACG-ECU 62 and the generator in the wire set 70 can be shortened. 43 The length of the connected part. Therefore, the material cost of the wire group 70 can be reduced.

Since the FI-ECU 61 and the ACG-ECU 62 are covered by the rear cover portion 53 of the vehicle body cover 6 from the outside in the vehicle body width direction, the FI-ECU 61 and the ACG-ECU 62 can be protected.

The FI-ECU 61 and the ACG-ECU 62 are arranged so as to be connected to each other via the wire group 70 and to face each other directly. With this configuration, since FI-ECU 61 and ACG-ECU 62 are very close to each other, the length of the portion of wire set 70 from the connection portion with FI-ECU 61 to the connection portion with ACG-ECU 62 can be shortened. Therefore, the material cost of the wire group 70 can be reduced.

In addition, the structure other than the structure demonstrated below is the same as that of 1st Embodiment.

The FI-ECU 61 is fixed to the power unit 4 and can swing up and down with respect to the vehicle body frame 2 together with the power unit 4 . The FI-ECU 61 is arranged at the rear of the engine 40 , which is its control object. The FI-ECU 61 is adjacent to the air cleaner 46 . The FI-ECU 61 is arranged between the air cleaner 46 and the arm portion 45 of the power unit 4 in a state in which the thickness direction of the main body portion 64 is along the vertical direction. The FI-ECU 61 is disposed so as to overlap with the mounting portion 48 of the air cleaner 46 when viewed from the side. The FI-ECU 61 is arranged below the center of gravity G (refer to FIG. 1 ) of the vehicle. The FI-ECU 61 is arranged such that the coupler 65 protrudes from the main body portion 64 in a direction inclined forward with respect to the vertical direction (in the example shown in the figure, forward and upward).

By arranging the FI-ECU 61 as described above, the FI-ECU 61 and the ACG-ECU 62 in the present embodiment have the following positional relationship. The FI-ECU 61 and the ACG-ECU 62 are arranged on opposite sides of each other with the vehicle body width center C as the center. The FI-ECU 61 and the ACG-ECU 62 are arranged so as to be shifted from each other in the front-rear direction so as not to overlap when viewed from the side. In the present embodiment, the FI-ECU 61 is arranged ahead of the ACG-ECUs 62 . In addition, the FI-ECU 61 and the ACG-ECU 62 are arranged so as not to overlap each other when viewed from the front, and to be offset from each other in the vertical direction and the vehicle body width direction. In the present embodiment, the FI-ECU 61 is arranged at the lower left than the ACG-ECUs 62 .

According to the two-wheeled locomotive 201 of the above-described third embodiment, in addition to the same functions and effects as those of the above-described first embodiment, the following functions and effects can be achieved.

The FI-ECU 61 and the ACG-ECU 62 are arranged so as not to overlap each other when viewed from the front. According to this configuration, the FI-ECU 61 is not blocked by the ACG-ECU 62 from the traveling wind in front of it, and the traveling wind can be directly blown to the FI-ECU 61 . Furthermore, the ACG-ECU 62 is not blocked by the FI-ECU 61 from the driving wind in front of it, and the driving wind can be directly blown to the ACG-ECU 62 . Therefore, the FI-ECU 61 and the ACG-ECU 62 can improve the respective air cooling performance.

The coupler 65 of the FI-ECU 61 protrudes in a direction inclined forward with respect to the vertical direction. According to this configuration, the coupler 65 of the FI-ECU 61 is directed toward the engine 40, which is the control object of the FI-ECU 61, with respect to the vertical direction. Therefore, the connection between the FI-ECU 61 and the engine 40 in the wire set 70 can be shortened. the length of the section. Therefore, the material cost of the wire group 70 can be reduced.

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

The FI-ECU 61 is arranged so as not to overlap the mounting portion 48 of the air cleaner 46 when viewed from the side. According to this structure, the dead space between the air cleaner 46 and the arm portion 45 of the power unit 4 can be utilized as the arrangement space of the FI-ECU 61 .

Further, in the present embodiment, although the FI-ECU 61 is arranged in front of the ACG-ECUs 62 , the FI-ECU 61 may be arranged in the rear of the ACG-ECUs 62 .

In addition, the present invention is not limited to the above-described embodiment described with the drawings, and various modifications can be conceived within the technical scope thereof. For example, in the above-mentioned embodiments, an example of applying the present invention to a scooter-type straddle-type vehicle is shown, but the present invention can be applied to all straddles where a rider rides a bicycle with his feet straddled on the vehicle body. riding vehicle. In other words, for example, the structure of the above-described embodiment may be combined with a two-wheeled locomotive or a three-wheeled locomotive or the like which does not have at least one of the footrest and the unit swing type rear suspension device.

In addition, the arrangement of the FI-ECU 61 and the ACG-ECU 62 is not limited to the arrangement in the above-described embodiment, and the arrangement may be such that the FI-ECU 61 and the ACG-ECU 62 are shifted in the front-rear direction. For example, in each embodiment, the FI-ECU 61 and the ACG-ECU 62 may be arranged to replace each other. Furthermore, both the FI-ECU 61 and the ACG-ECU 62 may be arranged below the footrest surface 12a.

In addition, the constituent elements in the above-described embodiments may be appropriately replaced by well-known constituent elements within the scope that does not deviate from the gist of the present invention, and each of the above-described embodiments and modifications may be appropriately combined .
