Summary of the utility model

Problems to be solved by the utility model

However, in recent years, with an increase in the amount of information processing in control units due to higher functionality and multifunction of saddle-ridden vehicles, there is a tendency for the control units to be larger in size and larger in heat generation. Therefore, the arrangement of the control unit is easily limited due to the necessity of air-cooling the control unit with good efficiency by enlarging the space occupied by the control unit. Therefore, it is required to suppress the increase in size and heat generation of the control unit.

Accordingly, the present utility model provides a saddle-ride type vehicle that can suppress enlargement of a control unit and heat generation.

Means for solving the problems

(1) A saddle-ride type vehicle according to a first aspect of the present utility model includes: an engine (40); a generator (43) that generates power using the output of the engine (40); a plurality of control units (60) that control the engine (40) and the generator (43); and a wire harness (70) connected to the plurality of control units (60), wherein the plurality of control units (60) include a first control unit (61) and a second control unit (62), and the first control unit (61) and the second control unit (62) are arranged so as to be staggered in the vertical direction.

According to this configuration, each control unit can be made smaller and the amount of heat generation can be suppressed as compared with the case where the engine and the generator are controlled by a single control unit. This can suppress the increase in size and heat generation of the entire control unit.

Further, the first control unit and the second control unit can be miniaturized, so that restrictions on the arrangement of the control units can be reduced. Therefore, the first control unit and the second control unit can be arranged to be shifted in the vertical direction. Thus, the plurality of control units and the wire harness connected to the control units can be distributed vertically, and the load distribution in the vertical direction of the saddle-ride type vehicle can be optimized.

(2) In the saddle-ride type vehicle according to (1), the first control unit (61) may control fuel injection and ignition of the engine (40), and the second control unit (62) may control the generator (43).

According to this configuration, the control portion of fuel injection and ignition, which particularly requires information processing capability, and the control portion of the generator are divided, so that the increase in size and heat generation of the entire control unit can be more reliably suppressed.

(3) In the saddle-ride type vehicle according to (1) or (2), the first control unit (61) and the second control unit (62) may be arranged so as to overlap each other when viewed from above.

According to this configuration, the arrangement of the portion of the wire harness from the connection portion connected to the first control unit to the connection portion connected to the second control unit can be facilitated.

(4) In the saddle-ride type vehicle according to (1) or (2), the first control unit (61) and the second control unit (62) may be arranged so as not to overlap each other when viewed from above.

According to this configuration, the first control means and the second control means which are disposed in a dispersed manner can be used for ensuring at least one of the weight balance in the front-rear direction and the weight balance in the left-right direction, which are particularly difficult to layout.

(5) In the saddle-ride type vehicle according to (3) or (4), the first control unit (61) and the second control unit (62) may be disposed above the muffler (8).

According to this structure, the mass is distributed toward the upper portion of the vehicle, and the moment of inertia in the roll direction increases, so that the stability during running can be improved.

(6) In the saddle-ride type vehicle according to the above (1) or (2), one of the first control unit (61) and the second control unit (62) may have a coupler (65, 67), the coupler (65, 67) may be disposed at a position rearward of a control object of the one of the engine (40) and the generator (43) and connected to the wire harness (70), and the coupler (65, 67) may protrude in a direction inclined forward with respect to the vertical direction.

According to this configuration, since the coupler of one of the first control unit and the second control unit is oriented toward the one control object side with respect to the up-down direction, the portion of the wire harness connecting the one of the first control unit and the second control unit to the one control object can be shortened. Therefore, the material cost of the wire harness can be reduced.

(7) In the saddle-ride type vehicle according to (1) or (2), the saddle-ride type vehicle may further include a vehicle body cover (6) that covers the first control unit (61) and the second control unit (62) from the outside in the vehicle width direction.

According to this structure, the first control unit and the second control unit can be protected by the vehicle body cover.

(8) In the saddle-ride type vehicle according to (1) or (2), the saddle-ride type vehicle may further include an air cleaner (46) that filters air taken in by the engine (40), and at least one of the first control unit (61) and the second control unit (62) may be adjacent to the air cleaner (46).

According to this configuration, the traveling wind is easily concentrated around the air cleaner, and therefore, the control units adjacent to the air cleaner among the first control unit and the second control unit can be effectively cooled.

(9) In the saddle-ride type vehicle according to (1) or (2), the saddle-ride type vehicle may further include: an arm (45) extending rearward from the housing of the engine (40) and supporting a rear wheel (5); an air cleaner (46) that filters air taken in by the engine (40); and a fixing portion (48) that connects the arm portion (45) and the air cleaner (46), wherein at least one of the first control unit (61) and the second control unit (62) is arranged so as to overlap the fixing portion (48) when viewed in the vehicle width direction.

According to this configuration, the dead space between the air cleaner and the arm portion can be effectively utilized as the arrangement space of at least one of the first control unit and the second control unit.

(10) In the saddle-ride type vehicle according to (1) or (2), the saddle-ride type vehicle may have a low floor (12) on which an occupant sits, and at least one of the first control unit (61) and the second control unit (62) may be disposed below a floor surface (12 a) of the low floor (12).

According to this configuration, in the saddle-ride type vehicle having the low floor pan for daily use, the mass is distributed toward the lower portion of the vehicle, and therefore the center of gravity can be set low, and stability at the time of stopping and pushing can be improved.

Effects of the utility model

According to the present utility model, a saddle-ride type vehicle can be provided in which the increase in size and heat generation of the control unit can be suppressed.

The configuration of the FI-ECU61 and the ACG-ECU62 will be described in detail.

As shown in fig. 2, FI-ECU61 is fixed to power unit 4 and can swing up and down with power unit 4 with respect to frame 2. The FI-ECU61 is disposed at a position rearward of the engine 40 to be controlled. FI-ECU61 is adjacent to air cleaner 46. The FI-ECU61 is disposed between the air cleaner 46 and the arm 45 of the power unit 4 in a state in which the thickness direction of the main body 64 is along the up-down direction. The FI-ECU61 is disposed so as to overlap the fixing portion 48 of the air cleaner 46 in a side view as seen in the vehicle width direction. FI-ECU61 is disposed below center of gravity G of the vehicle (see fig. 1). The FI-ECU61 is disposed such that the coupler 65 protrudes from the main body 64 in a direction inclined forward (forward in the illustrated example) with respect to the up-down direction.

As shown in fig. 1 and 2, the ACG-ECU62 is disposed at a position rearward of the generator 43 to be controlled. The ACG-ECU62 is fixed to the left rear frame 24 with its thickness direction along the vehicle width direction. The ACG-ECU62 is disposed at a position covered by the rear hood portion 53 of the body hood 6 from the outside in the vehicle width direction. The ACG-ECU62 is disposed above the vehicle center of gravity G. The ACG-ECU62 is disposed above the muffler 8. The ACG-ECU62 is disposed such that the first coupler 67 protrudes downward from the main body 66.

By disposing the FI-ECU61 and the ACG-ECU62 as described above, the FI-ECU61 and the ACG-ECU62 have the following positional relationship in the present embodiment.

Fig. 6 is a plan view showing a rear portion of the motorcycle according to the first embodiment. Fig. 6 shows a state in which the rear cover 53 of the body cover 6, the storage box 14, and the seat 7 are removed.

As shown in fig. 2 and 6, FI-ECU61 and ACG-ECU62 are disposed on the same side (left side) with respect to vehicle width center C of the vehicle. The FI-ECU61 and the ACG-ECU62 are arranged so as not to overlap each other in a side view and so as to be offset from each other in the vertical direction. In the present embodiment, the ACG-ECU62 is disposed above the FI-ECU 61. Specifically, the ACG-ECU62 is disposed such that the entire ACG-ECU is located above the center of gravity of the FI-ECU 61. The FI-ECU61 and the ACG-ECU62 are arranged so as to overlap each other when viewed from above.

As described above, the motorcycle 1 of the present embodiment includes the plurality of control units 60 that control the engine 40 and the generator 43. The FI-ECU61 and the ACG-ECU62 in the plurality of control units 60 are arranged so as to be offset in the vertical direction. According to this configuration, the FI-ECU61 and the ACG-ECU62 can be made smaller than in the case where the engine and the generator are controlled by a single control unit, and the amount of heat generation can be suppressed. This can suppress the increase in size and heat generation of the entire control unit 60.

Further, the FI-ECU61 and the ACG-ECU62 can be miniaturized, and thus the restrictions on the arrangement of the FI-ECU61 and the ACG-ECU62 can be reduced. Therefore, the FI-ECU61 and the ACG-ECU62 can be arranged so as to be shifted in the vertical direction. Accordingly, the FI-ECU61 and the ACG-ECU62 and the wire harness 70 connected to the FI-ECU61 and the ACG-ECU62 can be arranged in a dispersed manner in the vertical direction, so that the load distributed in the vertical direction of the motorcycle 1 can be optimized.

Further, by disposing the FI-ECU61 and the ACG-ECU62 in the plurality of control units 60 as described above, the control portion of fuel injection and ignition, which particularly requires information processing capability, and the control portion of the generator 43 are divided, and therefore, the enlargement and heat generation of the entire control unit 60 can be more reliably suppressed.

The FI-ECU61 and the ACG-ECU62 are arranged so as to overlap each other when viewed from above. According to this structure, the arrangement of the portion of the harness 70 from the connection portion connected to the FI-ECU61 to the connection portion connected to the ACG-ECU62 can be made easy.

The ACG-ECU62 is disposed above the muffler 8. According to this structure, the mass is distributed toward the upper portion of the vehicle, and the moment of inertia in the roll direction increases, so that the stability during running can be improved.

The ACG-ECU62 is covered by the rear hood portion 53 of the vehicle body hood 6 from the outside in the vehicle width direction, and therefore the FI-ECU61 and the ACG-ECU62 can be protected.

FI-ECU61 is adjacent to air cleaner 46. With this configuration, traveling wind is easily concentrated around the air cleaner 46, and therefore, the FI-ECU61 can be effectively cooled.

The FI-ECU61 is arranged to overlap the fixing portion 48 of the air cleaner 46 in a side view. According to this configuration, the dead space between the air cleaner 46 and the arm 45 of the power unit 4 can be effectively utilized as the arrangement space of the FI-ECU 61.

Modification of the first embodiment

Next, a modification of the first embodiment will be described with reference to fig. 7.

Fig. 7 is a left side view showing a rear portion of a motorcycle according to a modification of the first embodiment. Fig. 7 shows a state in which the body cover 6 is removed.

In the first embodiment, the ACG-ECU62 is disposed such that the first coupler 67 protrudes downward from the main body 66. However, in the modification shown in fig. 7, the ACG-ECU62 is disposed so that the first coupler 67 of the ACG-ECU62 protrudes from the main body 66 in a direction inclined forward with respect to the up-down direction. Accordingly, the first coupler 67 of the ACG-ECU62 is oriented toward the generator 43 side, which is the control target of the ACG-ECU62, with respect to the up-down direction, and therefore, the portion of the harness 70 connecting the ACG-ECU62 and the generator 43 can be shortened. Therefore, the material cost of the wire harness 70 can be reduced.

In the first embodiment, the ACG-ECU62 is fixed to the frame 2. However, in the modification shown in fig. 7, the ACG-ECU62 is fixed to the power unit 4 so as to be capable of swinging up and down with respect to the frame 2 together with the power unit 4. The ACG-ECU62 is adjacent to the air cleaner 46. The ACG-ECU62 is fixed to the air cleaner box 47. Thus, the traveling wind is easily concentrated around the air cleaner 46, and therefore the ACG-ECU62 can be effectively cooled. In this case, the ACG-ECU62 is preferably covered by the body cover 6 from the outside in the vehicle width direction. This can provide the same operational effects as those of the first embodiment.

Second embodiment

Next, a second embodiment will be described with reference to fig. 8 and 9.

Fig. 8 is a right side view of the motorcycle of the second embodiment. Fig. 9 is a plan view showing a rear portion of the motorcycle according to the second embodiment. Fig. 9 shows a state in which the rear cover 53 of the body cover 6, the storage box 14, and the seat 7 are removed.

In the first embodiment, the FI-ECU61 and the ACG-ECU62 are arranged so as to overlap each other when viewed from above. In contrast, the second embodiment is different from the first embodiment in that the FI-ECU61 and the ACG-ECU62 are arranged so as not to overlap each other when viewed from above. The configuration other than the following is the same as that of the first embodiment.

The ACG-ECU62 is disposed in front of the generator 43 that is the control target thereof. The ACG-ECU62 is disposed between the first extending portions 24a of the pair of rear frames 24 as viewed from above, and is fixed to the cylinder portion 42 of the engine 40. The ACG-ECU62 is disposed below the vehicle center of gravity G. The ACG-ECU62 is covered by the rear hood portion 53 of the body hood 6 from the front and the outside in the vehicle width direction.

By arranging the ACG-ECU62 as described above, in the present embodiment, the FI-ECU61 and the ACG-ECU62 have the following positional relationship.

FI-ECU61 and ACG-ECU62 are disposed on the same side (left side) with respect to vehicle width center C. The FI-ECU61 and the ACG-ECU62 are arranged so as not to overlap each other in a side view and so as to be offset from each other in the vertical direction. In the present embodiment, the ACG-ECU62 is disposed above the FI-ECU 61. The FI-ECU61 and the ACG-ECU62 are arranged so as to be offset from each other in the vehicle width direction and the front-rear direction so as not to overlap each other when viewed from above. In the present embodiment, the ACG-ECU62 is disposed in a position forward and rightward of the FI-ECU 61.

According to the motorcycle 101 of the second embodiment described above, the following operational effects are provided in addition to the operational effects similar to those of the first embodiment described above.

The FI-ECU61 and the ACG-ECU62 are arranged so as not to overlap each other when viewed from above. According to this configuration, FI-ECU61 and ACG-ECU62 that are distributed can be used to ensure weight balance in the front-rear direction and weight balance in the left-right direction, which are particularly difficult to layout.

In the present embodiment, the FI-ECU61 is disposed above the ACG-ECU62. The FI-ECU61 and the ACG-ECU62 are arranged so as to be offset from each other in the front-rear direction so as not to overlap each other when viewed from above. In the present embodiment, the ACG-ECU62 is disposed in front of the FI-ECU 61.

According to the motorcycle 201 of the third embodiment described above, the following operational effects are provided in addition to the operational effects similar to those of the first embodiment described above.

The FI-ECU61 and the ACG-ECU62 are arranged so as not to overlap each other when viewed from above. According to this configuration, FI-ECU61 and ACG-ECU62 can be used in a distributed arrangement to ensure weight balance in the front-rear direction, which is particularly difficult to layout.

The ACG-ECU62 is disposed below the floor surface 12a of the floor step 12. According to this configuration, in the scooter type motorcycle 101 having the bottom pedal 12 for daily use, the mass is distributed toward the lower portion of the vehicle, and therefore the center of gravity can be set low, and stability at the time of stopping and pushing can be improved.

The present utility model is not limited to the embodiment described above with reference to the drawings, and various modifications are considered within the technical scope thereof.

For example, although the above embodiment shows an example in which the present utility model is applied to a saddle-ride type vehicle of a scooter type, the present utility model can be applied to all saddle-ride type vehicles in which a driver rides across a vehicle body. That is, the structure of the above-described embodiment may be combined with, for example, a motorcycle, a tricycle, or the like that does not have at least one of the bottom step and the unit swing type rear suspension.

The arrangement of the FI-ECU61 and the ACG-ECU62 is not limited to the arrangement in the above embodiment, as long as the FI-ECU61 and the ACG-ECU62 are arranged so as to be offset in the up-down direction. For example, the FI-ECU61 and the ACG-ECU62 may be configured alternately in each embodiment.

The components in the above-described embodiments may be replaced with known components as appropriate within a range not departing from the gist of the present utility model, and the above-described embodiments and modifications thereof may be appropriately combined.
