[0127] figure 1 It is a front view which schematically shows the motorcycle of 1st Embodiment of this invention.

[0128] The two-wheeled motor vehicle 10 is an example of a vehicle that turns with a leaning posture according to the present invention. In the present invention, the vehicle turning in a leaning posture is not particularly limited, and examples thereof include saddled vehicles such as motorcycles, tricycles, snowmobiles, and ATVs (all-terrain vehicles). In addition, in the following description, "front and rear" refers to the traveling direction of the vehicle, "up and down" refers to the up and down direction of the vehicle, and "left and right" refers to the driver.

[0129] The motorcycle 10 includes a handlebar 12 . An operation switch 15 is provided on the left portion of the handlebar 12 in the vehicle width direction. The operation switches 15 include a beam switching switch 15B and a flasher switch 15F (refer to figure 2 ). A steering shaft (not sho...

[0298] In the first embodiment described above, the inclination angle reaches the reference value K (K 1 ~K 3 ), the auxiliary headlight light source is at the first brightness Q1 lights up, the inclination angle changes from the reference value K (K 1 ~K 3 ) becomes the upper side value U (U 1 ~ U 3 ), from the first luminance Q 1 Change to the second brightness Q 2 situation is explained. However, the present invention is not limited to this example, and, for example, the second embodiment can be employed.

[0299] Figure 19 It is a graph showing the relationship between the lean angle of the motorcycle 10 and the brightness of the sub headlight light source in the second embodiment of the present invention.

[0300] In the motorcycle 10 of the second embodiment of the present invention, the upper value U is not set (U 1 ~ U 3 ). In the motorcycle 10 of the second embodiment, as Figure 19 As shown, the inclination angle of the motorcycle 10 has reached the lowe...

Abstract

The present invention provides a sub headlight unit for a vehicle turning with a leaning posture, capable of suppressing a driver from feeling uncomfortable with a change in an illumination range. The sub headlight unit for a vehicle turning with an inclined posture according to the present invention, the sub headlight unit has a sub headlight light source for facing the vehicle width direction outer side of the vehicle on one side in the vehicle width direction. And irradiating light forward, the brightness of the sub headlight light source changes according to the inclination angle of the vehicle, and the sub headlight light source is at an inclination angle at which the vehicle is inclined to the one side in the vehicle width direction. When the reference value set for the sub headlight light source is reached, it is lit with the first brightness, and when the lean angle of the vehicle reaches a lower value smaller than the reference value and reaches the reference value, Lighten dimmer than the first brightness.

Description

technical field [0001] The present invention relates to a sub headlight unit and a sub headlight system for a vehicle turning in a leaning posture, and a vehicle turning in a leaning posture. Background technique [0002] In general, in a vehicle that turns with a leaning posture (for example, motorcycles, motorcycles, snowmobiles, ATVs (all-terrain vehicles) and other riding-type vehicles), when turning or turning at an intersection, in order to Against the centrifugal force acting on the vehicle body, the driver operates the handlebars and moves the driver's own body center of gravity. As a result, the vehicle turns with a posture leaning toward the inner side of the curve (hereinafter referred to as “lean posture”). On the other hand, in a vehicle that does not turn with a leaning posture, such as a motor vehicle, when turning or turning at an intersection, the driver operates the handlebars and turns while receiving centrifugal force acting on the vehicle body. Therefo...
