JP 2015-99654 A

However, when a conventional sequential lighting turn indicator device is applied to a saddle-ride type vehicle, there is a possibility that the number of light sources may be restricted due to layout considerations such as vehicle width dimension restrictions. Fluid lighting, which is the purpose of sequential lighting, becomes more difficult as the number of light sources decreases.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a saddle-riding vehicle equipped with a direction indicating device capable of fluid lighting with a small number of light sources.

The direction indicator device of the present invention comprises a first light source (11) and a second light source (12) that emit light for direction indication, and a housing containing the first light source (11) and the second light source (12). (20), and a control section (4) for controlling the first light source (11) and the second light source (12), wherein the control section (4) controls the first light source (11) to the first light source (11). While emitting light in one light emitting mode, the second light source (12) is caused to emit light in a second light emitting mode different from the first light emitting mode overlapping with the light emission of the first light source (11) , and the first light emitting mode is characterized in that the luminance of the second light emission mode increases when the luminance of the second light emission mode decreases .

According to the present invention, the first light source and the second light source emit light in mutually different light emission modes, thereby providing a lighting mode of the turn indicator device in which the light emission mode of the light source changes midway through. Therefore, unlike simple lighting in which the first light source and the second light source emit light in the same manner, even with two light sources, the turn indicator device can be lighted in a fluid manner.

In the direction indicator device described above, the first light emission mode and the second light emission mode may have different rises in brightness.

According to the present invention, it is possible to differentiate the time until the luminance reaches the peak in each of the first light source and the second light source. As a result, the lighting of the direction indicating device can be expressed more fluidly.

In the direction indicator device described above, the second light source (12) is arranged further outward in the vehicle width direction than the first light source (11), and the rise of luminance in the second light emission mode is equal to the first light emission. It may be slower than the rising edge of the brightness of the aspect.

According to the present invention, the lighting of the turn signal device rises so that the time until the brightness of the light source on the outside in the vehicle width direction reaches its peak becomes longer. Therefore, the turn indicator device can be illuminated so as to flow toward the course direction of the vehicle.

In the direction indicating device described above, the timing at which the luminance of the second light emission mode reaches its peak may be later than the timing at which the luminance of the first light emission mode reaches its peak.

According to the present invention, a light source having a shorter time to peak luminance emits light, followed by a longer light source. Therefore, lighting of the direction indicating device can be expressed more fluidly.
In the direction indicator device described above, the timing at which the luminance of the second light emission mode reaches a peak may be later than the timing at which the luminance of the first light emission mode starts to decrease.

A saddle-ride type vehicle according to the present invention is characterized by comprising the direction indicating device (2) described above.

According to the present invention, it is possible to provide a saddle-riding vehicle equipped with a direction indicating device that lights up dynamically.

A straddle-type vehicle of the present invention accommodates a first light source (11) and a second light source (12) that emit light for direction indication, and the first light source (11) and the second light source (12). a direction indicator device (2) comprising a housing (20) and a controller (4) for controlling said first light source (11) and said second light source (12), said controller (4) comprising: The first light source (11) emits light in a first light emission mode, and the second light source (12) overlaps the light emission of the first light source (11) in a second light emission mode different from the first light emission mode. and the control unit (4) changes the blinking period of the first light source (11) and the second light source (12) according to the bank angle.

According to the present invention, when the behavior of the vehicle changes greatly, such as driving on a sharp curve, the state of the vehicle can be represented by the direction indicating device.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. Note that directions such as front, rear, up, down, left, and right in the following description are the same as the directions of the vehicle described below. That is, the vertical direction corresponds to the vertical direction, and the horizontal direction corresponds to the vehicle width direction. In the drawings used for the following description, an arrow UP indicates upward, an arrow FR indicates forward, and an arrow LH indicates leftward.

FIG. 1 is a left side view of the motorcycle of the embodiment.
As shown in FIG. 1, this embodiment is applied to a motorcycle 1 that is a straddle-type vehicle. A motorcycle 1 is provided with a direction indicating device 2 . The direction indicator device 2 includes a pair of left and right direction indicators 3 arranged respectively at the front and rear parts of the motorcycle 1 and a control unit 4 that controls lighting of each of the direction indicators 3 . Since the front, rear, left, and right direction indicators 3 have the same configuration, the following explanation of the configuration of the direction indicators 3 will take the direction indicator arranged on the front left side of the motorcycle 1 as an example. explain.

FIG. 2 is a front view showing the direction indicator according to the embodiment; FIG. 3 is a front view showing the inside of the direction indicator according to the embodiment;
As shown in FIG. 2, the direction indicator 3 includes a first light source 11 and a second light source 12 that emit light for direction indication, and a housing 20 that houses the first light source 11 and the second light source 12. . The housing 20 includes a base portion 21 that supports the first light source 11 and the second light source 12, and a lens 22 that covers the first light source 11 and the second light source 12 from the front. The base portion 21 is formed so that its longitudinal direction is the vehicle width direction when viewed from the front-rear direction. The lens 22 is attached to the base portion 21 . The lens 22 follows the shape of the base portion 21 and is formed so that its longitudinal direction is the vehicle width direction when viewed from the front-rear direction. Lens 22 is configured as a blinker lens that covers first light source 11 and second light source 12 .

The first light source 11 and the second light source 12 are, for example, light emitting diodes. The first light source 11 and the second light source 12 are arranged side by side in the vehicle width direction behind the lens 22 . The second light source 12 is arranged further outward in the vehicle width direction than the first light source 11 . Light emission of the first light source 11 and the second light source 12 is controlled by the controller 4 .

The control unit 4 controls voltages applied to the first light source 11 and the second light source 12 . The control unit 4 controls the light emitting modes of the first light source 11 and the second light source 12 according to the operation of the blinker switch by the passenger, the output of the acceleration sensor, the tilt sensor, etc. (not shown), and the like. Specifically, when the blinker switch is operated by the passenger, the control unit 4 intermittently applies a voltage to the first light source 11 and the second light source 12 to intermittently turn on the first light source 11 and the second light source 12 . to emit light. As a result, the direction indicator 3 blinks.

FIG. 4 is a graph showing the relationship between time and luminance for the first light source and the second light source of the embodiment. FIG. 4 shows the luminance of each of the first light source 11 and the second light source 12 when the direction indicator 3 blinks once.
As shown in FIG. 4, when blinking the direction indicator 3, the control unit 4 causes the first light source 11 to emit light in the first light emission mode A1 each time the light is turned on. Then, the second light source 12 is caused to emit light in a second light emission mode A2 different from the first light emission mode A1. The first light emission mode A1 and the second light emission mode A2 differ in the rise of luminance. The rise of luminance is the process from the start of light emission to the peak luminance. Assuming that the luminance of each of the first light source 11 and the second light source 12 is a function having the time from the start of light emission as a variable, those functions need not be proportional to each other. In the present embodiment, the rise in luminance of the second light emission mode A2 is slower than that of the first light emission mode A1. That is, the brightness of the second light source 12 is lower than the brightness of the first light source 11 until the brightness of the first light source 11 reaches the peak brightness. The timing T2 at which the brightness peaks in the second light emission mode A2 is later than the timing T1 at which the brightness peaks in the first light emission mode A1.

The first light emission mode A1 will be described in detail. The first light emission mode A1 includes a rising period and a falling period. The rising period is a period from the light emission start time Ts of the first light source 11 to the timing T1 when the luminance of the first light source 11 reaches the peak luminance L1. During the rising period, the control unit 4 controls the first light source 11 so as to continuously increase the luminance of the first light source 11 to the maximum luminance L1. The control unit 4 causes the first light source 11 to emit light so that the maximum value of the luminance gradient (luminance change rate) of the first light source 11 becomes G1 in the rising period. The falling period is continuous with the rising period. The fall period is a period from time T1 at which the luminance of the first light source 11 starts to decrease from the peak luminance L1 to timing Te at which the first light source 11 is extinguished. During the falling period, the control unit 4 controls the first light source 11 so as to continuously decrease the luminance of the first light source 11 . The control unit 4 causes the first light source 11 to emit light so that the minimum value of the luminance gradient of the first light source 11 is G2 in the fall period. The absolute value of the luminance gradient G2 is smaller than the luminance gradient G1 during the rise period. The temporal length of the falling period is greater than the temporal length of the rising period. In the first light emission mode A1, a period may be provided between the rising period and the falling period during which the first light source 11 emits light at the peak luminance L1 for a certain period of time.

The second light emission mode A2 will be described in detail. The second light emission mode A2 includes a rising period and a falling period. The rising period is a period from the light emission start time Ts of the second light source 12 to the timing T2 when the luminance of the second light source 12 reaches the peak luminance L2. The peak luminance L2 of the second light source 12 is equal to the peak luminance L1 of the first light source 11 . The light emission start time Ts of the second light source 12 coincides with the light emission start time Ts of the first light source 11 . During the rising period, the control unit 4 controls the second light source 12 to continuously increase the luminance of the second light source 12 to the peak luminance L2. The control unit 4 causes the second light source 12 to emit light so that the maximum value of the luminance gradient of the second light source 12 is G3 in the rising period. The luminance gradient G3 is smaller than the luminance gradient G1 of the first light source 11 . As a result, the rise in luminance of the second light emission mode A2 is slower than that of the first light emission mode A1. The control unit 4 controls the second light source 11 so that the luminance of the second light source 12 reaches the peak luminance L2 in a state in which the first light source 11 is after the rise period (that is, in a state in which the first light source 11 is in the fall period). Control the light source 12 . As a result, the timing T2 at which the brightness peaks in the second light emission mode A2 is later than the timing T1 at which the brightness peaks in the first light emission mode A1.

The falling period is continuous with the rising period. The falling period is a period from time T2 when the luminance of the second light source 12 starts to decrease from the peak luminance L3 to when the second light source 12 is extinguished. During the fall period, the controller 4 controls the second light source 12 to continuously decrease the brightness of the second light source 12 . The control unit 4 causes the second light source 12 to emit light so that the minimum value of the luminance gradient of the second light source 12 is G4 in the fall period. The luminance gradient G4 is smaller than the luminance gradient G3 of the first light source 11 . The time Te when the second light source 12 is turned off coincides with the time Te when the first light source 11 is turned off. That is, the temporal length of the fall period of the second light emission mode A2 is shorter than the temporal length of the fall period of the first light emission mode A1. In the second light emission mode A2, a period may be provided between the rising period and the falling period during which the second light source 12 emits light at the peak luminance L2 for a certain period of time.

FIG. 5 is a graph showing the relationship between time and luminance when the direction indicator of the embodiment blinks.
As shown in FIG. 5, the control unit 4 changes the blinking cycle of the direction indicator 3 according to at least one of the bank angle of the vehicle body and the magnitude of acceleration. Specifically, in a state where the turn signal switch is operated and the direction indicator 3 is blinking, the control unit 4 controls the first light source 11 and the second light source so that the blinking period becomes shorter as the bank angle of the vehicle body increases. 12 is controlled. Further, the control unit 4 controls the first light source 11 and the second light source 12 so that the blinking period becomes shorter as the absolute value of the acceleration increases in a state where the turn signal switch is operated and the direction indicator 3 blinks. Control. The control unit 4 does not change the first light emission mode A1 and the second light emission mode A2, but changes the extinguishing period to change the blinking cycle. When changing the blinking cycle, the control unit 4 may change the first light emission mode A1 and the second light emission mode A2 so as to shorten the light emission time of the first light source 11 and the second light source 12.

As described above, the direction indicating device 2 of this embodiment includes the control section 4 that controls the first light source 11 and the second light source 12 . The control unit 4 causes the first light source 11 to emit light in a first light emission mode A1, and causes the second light source 12 to emit light in a second light emission mode A2 different from the first light emission mode A1 in overlap with the light emission of the first light source 11. Let According to this configuration, the first light source 11 and the second light source 12 overlap and emit light in different light emission modes, so that the lighting mode of the direction indicating device in which the light emission modes of the light sources change midway is obtained. Therefore, unlike simple lighting in which the first light source 11 and the second light source 12 emit light in the same manner, even with two light sources, the direction indicator 3 can be lighted in a fluid manner.

In addition, since fluid lighting is realized by the two light sources, it is possible to prevent the size of the direction indicator 3 in the vehicle width direction from becoming too large relative to the size in the vertical direction. Therefore, it is possible to provide the direction indicator device 2 that is less likely to be restricted by the layout of the motorcycle 1 .

Also, the first light emission mode A1 and the second light emission mode A2 differ in the rise of luminance. According to this configuration, the time required for the luminance to reach the peak can be differentiated between the first light source 11 and the second light source 12 . Thereby, the direction indicator 3 can be expressed more fluidly.

In addition, since the luminance of each of the first light source 11 and the second light source 12 is continuously changed, the direction indicator 3 can be lit so that the brightest part moves smoothly.

Further, the second light source 12 is arranged outside the first light source 11 in the vehicle width direction. The rise in brightness of the second light emission mode A2 is slower than the rise in brightness of the first light emission mode A1. According to this configuration, the lighting of the direction indicator 3 rises so that the time until the brightness of the light source on the outside in the vehicle width direction reaches its peak becomes longer. Therefore, the direction indicator 3 can be turned on so as to flow toward the course direction of the vehicle.

Further, the timing T2 at which the brightness of the second light emission mode A2 peaks is later than the timing T1 at which the brightness of the first light emission mode A1 peaks. In this configuration, the light source whose brightness peaks in a short time emits light, and then the light source whose brightness peaks in a long time emits light. Therefore, lighting of the direction indicator 3 can be expressed more fluidly.

The motorcycle 1 also includes the direction indicating device 2 described above. According to this configuration, it is possible to provide the motorcycle 1 equipped with the direction indicator device 2 that lights up in a fluid manner.

Further, the control unit 4 changes the blinking cycle of the direction indicator 3 according to the bank angle of the vehicle body. Therefore, when the behavior of the vehicle changes greatly, such as driving on a sharp curve, the direction indicator 3 can express the state of the vehicle.

Further, the control unit 4 changes the blinking period of the direction indicator 3 according to the magnitude of the acceleration. Therefore, when the behavior of the vehicle changes greatly, such as sudden braking or sudden acceleration, the direction indicator 3 can express the state of the vehicle.

It should be noted that the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications are conceivable within its technical scope.
For example, in the above-described embodiment, the housing 20 is formed so that its longitudinal direction is the vehicle width direction when viewed from the front-rear direction, but the outer shape of the direction indicator 3 is not limited to this. For example, the direction indicator may be formed in a circular shape when viewed from the front.

Further, in the above embodiment, the maximum luminance L1 of the first light source 11 in the first light emission mode A1 and the maximum luminance L2 of the second light source 12 in the second light emission mode A2 are equal, but they are different. good too.

In addition, the control unit 4 of the above-described embodiment adjusts the timing T1 when the luminance of the first light source 11 reaches its peak and the luminance of the second light source 12 reaches its peak according to changes in behavior such as the bank angle and acceleration of the vehicle body. At least one of the timings T2 may be changed.

Further, in the above-described embodiment, the control unit 4 is configured to change the blinking cycle of the direction indicator 3 in a state where the blinker switch is operated and the direction indicator 3 is blinking. However, the control unit blinks the direction indicator 3 when the behavior of the vehicle exceeds a predetermined threshold due to, for example, sudden braking, and changes the blinking period of the direction indicator 3 according to the magnitude of the change in behavior. You may let

Moreover, in the above-described embodiment, an example in which the direction indicating device of the present invention is applied to a motorcycle has been shown, but the configuration of the above-described embodiment may be combined with, for example, a three-wheeled motor vehicle.

In addition, in the above-described embodiment, the front, rear, left, and right direction indicators 3 are configured in the same manner, but the present invention is not limited to this. For example, the present invention may be applied only to the front left and right direction indicators or the rear left and right direction indicators.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the scope of the present invention.
