The headlight light source and the cornering light light source can each be configured by LEDs.

FIG. 5 is a perspective view of the headlight unit 40 from which the outer lens 42 has been removed as viewed from above the vehicle body. Further, FIG. 6 is a perspective view of the headlight unit 40 as viewed from the lower side of the vehicle body. A harness 58 that supplies electric power to the headlight 12 is introduced at substantially the center of the rear wall of the housing 41. In front of the harness 58, a blindfold member 57 (only the right half is shown in FIG. 5) made of a thin plate material bent in a staircase pattern is arranged.

The first reflector 61, the second reflector 62, and the third reflector 63, which form three reflectors on one side, are formed so as to be located on the rear side of the vehicle body toward the outside in the vehicle width direction. As a result, the outer shape of the cornering light 60 in the plan view of the vehicle body is a substantially V-shape that inclines toward the rear side of the vehicle body from the center in the vehicle width direction to the left and right. You can get the light 60.

The first reflector 61 on the outer side in the vehicle width direction is provided with an outer reflecting portion 61a that reflects the irradiation light of the light source on the outer side in the vehicle width direction at the end portion on the vehicle body center side of the curved surface that is convex toward the rear side of the vehicle body. Has been done. Above each of the reflectors 61, 62, 63, a substrate 80 on which a light source for a cornering light facing downward from the openings 71, 72, 73 is mounted is arranged.

With reference to FIG. 6, the headlight 12 is fixed to a base member 48 whose holding angle with respect to the housing 41 can be adjusted by operating the adjustment knob 49. As a result, the optical axis of the headlight 12 can be adjusted by operating the adjustment knob 49. On the other hand, the case 90 of the cornering light 60 is supported by the housing 41 by the central shaft 51 at the center in the vehicle width direction and a pair of left and right support portions 64, and the optical axis is adjusted by the screw mechanism provided on the central shaft 51 and the support portions 64. Is configured to be possible.

The cornering light 60 is configured so that the three reflectors 61, 62, 63 on one side are located on the rear side of the vehicle body toward the outside in the vehicle width direction, thereby providing a predetermined space between the rear surface of the case 90 and the housing 41. Have. In the present embodiment, the cornering light driver 83 (hereinafter, may be simply referred to as the driver 83) that controls the lighting of the cornering light light sources 81a, 81b, and 81c is arranged by utilizing this space. Further, a harness 84 for supplying electric power to the cornering light 60 is introduced into the housing 41 on the left side of the driver 83 in the vehicle width direction. Since the case 90 is located in front of the vehicle body of the driver 83 and the harness 84, the driver 83 and the harness 84 are not visible from the outside of the vehicle body.

FIG. 7 is a perspective view of the cornering light 60 as viewed from the front side of the vehicle body. Further, FIG. 8 is a perspective view of the cornering light 60 as viewed from the rear side of the vehicle body. The first light source 81a corresponding to the first reflector 61, the second light source 81b corresponding to the second reflector 62, and the third light source 81c corresponding to the third reflector 63 are arranged in a substantially horizontal direction when viewed from the front of the vehicle body. As a result, the cornering light 60 can be miniaturized by housing the plurality of light sources side by side in the substantially horizontal direction in the integrated case 90. Further, in the illustration, each light source is mounted on an independent substrate 80, but since each light source is arranged in the horizontal direction, it becomes easy to mount a plurality of light sources on the same substrate, whereby the number of parts is increased. Can be reduced.

Further, since the first light source 81a, the second light source 81b, and the third light source 81c are arranged on the rear side of the vehicle body toward the outside in the vehicle width direction, the light source outside the vehicle width direction causes the vehicle width direction in the vicinity of the vehicle. It becomes easy to obtain the irradiation light required for illuminating the outside. In the present embodiment, the light source that lights up when the lean angle of the motorcycle 1 is small is configured to be located on the outermost side in the vehicle width direction. As a result, when the lean angle is small, it becomes easy to irradiate the road surface outside the vehicle width direction in the vicinity of the vehicle.

The first light source 81a, the second light source 81b, and the third light source 81c are mounted on the lower surface of the substrate 80 arranged so that the flat surface portion is directed in the vertical direction of the vehicle body, and the irradiation light of each of the light sources 81a, 81b, 81c. Is reflected in the front of the vehicle body by the reflectors 61, 62, 63 arranged below the substrate 80, so that the light sources 81a, 81b, 81c are difficult to see from the outside of the vehicle body, and the appearance of the cornering light 60 is improved. It becomes possible to increase. Further, since the upward protruding portion 65 supporting the central shaft 51 is covered with the central portion of the front cowl 9, the vehicle is not seen in the completed state. From the lower ends of the reflectors 61, 62, 63, a flat surface portion 94 extending to the front of the vehicle body and forming the lower edge of the irradiation range is formed.

Further, the cornering light 60 is detachably fixed to the housing 41. This makes it possible to easily separate the specifications having the cornering light 60 and the specifications not having the cornering light 60 when assembling the headlight. Further, since the shape of the headlight unit 40 does not change even if the specifications do not have the cornering light 60, the degree of freedom in vehicle body design can be increased as compared with the configuration in which the headlight 12 and the cornering light 60 are separated. ..

FIG. 9 is a block diagram showing a configuration of a lighting control system for the cornering light 60.
The ECU 100 includes a light lighting control unit 102 and a cornering light lighting determination unit 101. When the headlight 12 is always lit, the light lighting control unit 102 transmits a drive command to the headlight driver 59 when the IG switch 102 is turned on. The cornering light lighting determination unit 101 determines the lighting of the cornering light light sources 81a, 81b, 81c only while the light lighting control unit 102 is being driven.

When the cornering light lighting determination unit 101 has a vehicle speed V of a predetermined value or more and a lean angle of a predetermined value or more according to the lean angle θ detected by the lean angle sensor 17a and the vehicle speed V detected by the vehicle speed sensor 17b. , One of the cornering light light sources 81a, 81b, 81c is turned on. Specifically, when the vehicle speed is 5 km / h or more and the lean angle θ is 10 degrees or more and less than 20 degrees, the first light source 81a is turned on, and when the vehicle speed is 5 km / h or more and the lean angle θ is 20 degrees or more and 30 degrees. If it is less than, the first light source 81a and the second light source 81b are turned on, and if the vehicle speed is 5 km / h or more and the lean angle θ is 30 degrees or more, the three light sources 81a, 81b, 81c are turned on. Can be configured as

In the above-mentioned lighting determination, the number of lights increases from the inside to the outside in the vehicle width direction as the lean angle increases. For example, the number of lights is fixed to one and the lean angle increases. The lighting position may be switched as the lighting position is changed, or the first light source 81a may be dimmed as the second light source 81b is turned on. In this case, the second light source 81b may be dimmed and the first light source 81a may be extinguished as the third light source 81c is turned on.

FIG. 10 is an explanatory view showing an image of irradiation by the cornering light 60. When the vehicle body leans during cornering, the irradiation range A formed on the road surface G by the headlights 12 moves to the side opposite to the turning direction. The cornering light 60 according to the present embodiment uses a light source that is independent from the headlight 12 to compensate for the insufficient irradiation range in the turning direction during cornering traveling. This figure shows a state in which the irradiation range B is formed in the turning direction by the cornering light 60 when the vehicle body leans to the right at the right corner.

FIG. 11 is an explanatory diagram showing the shapes of the irradiation range A1 by the headlight 12 and the first irradiation range B1 by the first light source 81a. Since the headlight 12 irradiates the irradiation light from a high position near the upper part of the vehicle body toward the front lower part of the vehicle body, when the vehicle body leans to the right side, the irradiation range A1 formed on the road surface G moves to the left and the irradiation light 12 thereof. The outer edge r1 is also inclined to the left.

In the present embodiment, the irradiation range B1 by the first light source 81a inside in the vehicle width direction extends outward in the vehicle width direction from the position of the main bulging portion C1 extending forward of the vehicle body and the position of the main bulging portion C1 near the rear of the vehicle body. It has a sub-bulging portion C2 that extends. Even in the elliptical main bulging portion C1 extending to the front of the vehicle body, the right edge portion D1 is located on the right side of the irradiation range A1 of the headlight 12 to supplement the irradiation range in the turning direction, but the main bulge The sub-bulging portion C2 extending substantially in the vehicle width direction from the right edge portion D1 of the protruding portion C1 plays a role different from that of the main bulging portion C1 by more positively directing to the outside in the vehicle width direction.

The sub-bulging portion C2 is mainly formed by the shape of the first reflector 61 corresponding to the first light source 81a and the outer reflecting portion 61a provided at the end of the first reflector 61. By forming such a sub-bulging portion C2, it is possible to simultaneously irradiate the front of the vehicle body and the outside in the vehicle width direction.
