Description

[Technical Field]

[0001] The present disclosure relates to a front turn lamp, a vehicle headlamp. [Background technology]

[0002] Japanese Patent No. 5664900 (Patent Document 1) describes an optical unit for a vehicle configured to form a light distribution for a front turn lamp. In the light distribution for a front turn lamp formed by this optical unit for a vehicle, the illumination area where the luminous intensity exceeds 100 cd is in a range of approximately 20° above and 10° below the horizon in the vertical direction, and in a range of 23° on both the left and right sides of the vertical direction. This illumination area is typical for a light distribution for a front turn lamp.

[0003] However, when using front turn lamps that light up (blink) with the above-mentioned front turn lamp light distribution, from the driver's point of view, the light emitted by the front turn lamps is hard to see, making it difficult for the driver to realize that the front turn lamps are on. This can lead to the driver forgetting to turn the front turn lamps on or off. [Prior art documents] [Patent documents]

[Figure 6] FIG. 6 is a block diagram for explaining the configuration of a vehicle headlamp according to the second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] (First embodiment) Fig. 1 is a block diagram for explaining the configuration of a vehicle headlamp according to the first embodiment. The vehicle headlamp according to the first embodiment is configured to include a left headlamp 1L and a right headlamp 1R. As shown schematically in Fig. 3, which will be described later, the left headlamp 1L is installed on the front left side of the vehicle 100, and the right headlamp 1R is installed on the front right side of the vehicle.

[0010] The left headlight 1L and the right headlight 1R are each connected to a turn signal lever 2 installed at the driver's seat of the vehicle. Note that the term "connected" here does not necessarily mean a direct connection via wiring or the like, but also includes an indirect connection so that a signal can be received via a vehicle control device or the like (not shown).

[0011] The left headlamp 1L includes a lamp (Lo / Hi) 10L for emitting low and high beams in front of the vehicle, and a front turn lamp 11L (first front turn lamp) that functions as a turn signal. The front turn lamp 11L is configured with a built-in front-illuminating lamp 12L and a side-illuminating lamp 13L. The front turn lamp 11L emits amber flashing light as a turn signal mainly to the area in front of the left side of the vehicle and the area diagonally forward and to the left side of the vehicle. The front-illuminating lamp 12L emits flashing light to the area in front of the vehicle. The side-illuminating lamp 13L emits flashing light to the area diagonally forward and to the left side of the vehicle.

[0012] The right headlamp 1R includes a lamp (Lo / Hi) 10R for emitting low and high beams in front of the vehicle, and a front turn lamp 11R (second front turn lamp) that functions as a turn signal. The front turn lamp 11R incorporates a front-illuminating lamp 12R and a side-illuminating lamp 13R. The front turn lamp 11R emits amber flashing light as a turn signal mainly in the area in front of the vehicle on the right side and in the area diagonally forward to the right of the vehicle. The front-illuminating lamp 12R emits flashing light in the area in front of the vehicle. The side-illuminating lamp 13R emits flashing light in the area diagonally forward to the right of the vehicle.

[0013] The side-illuminating lamps 13L, 13R may be configured separately from the front turn lamps 11L, 11R, rather than being built into the front turn lamps 11L, 11R. The front-illuminating lamp 12L and the side-illuminating lamp 13L may each be configured by combining separate light sources with light distribution control lenses, or by combining separate light sources with light distribution control lenses integrally formed therewith. The same applies to the front-illuminating lamp 12R and the side-illuminating lamp 13R.

[0014] Each front turn lamp 11L, 11R operates in response to the state of the turn signal lever 2 operated by the driver. For example, when the turn signal lever 2 is in a state indicating a left turn, the forward-illuminating lamp 12L and the side-illuminating lamp 13L of the front turn lamp 11L of the left headlight 1L each emit a flashing light. When the turn signal lever 2 is in a state indicating a right turn, the forward-illuminating lamp 12R and the side-illuminating lamp 13R of the front turn lamp 11R of the right headlight 1R each emit a flashing light.

[0015] FIG. 2 is a diagram illustrating the field of view of the driver of the vehicle. FIG. 2 shows a schematic plan view of the vehicle 100 as viewed from above. Here, it is assumed that the driver's seat of the vehicle 100 is located on the right side, and the driver's viewpoint is P. The angle of view of an area R1 visible from the front window of the vehicle 100 ranges, for example, from 70° on the left to 25° on the right. The angle of view of an area R2 visible from the right side window, which is behind the pillar 101 of the vehicle 100, ranges, for example, from 30° on the right to 90° on the right. The legal light distribution range (front turn light distribution standard range) is a range of 80° on the left to 45° on the right or a range of 45° on the left to 80° on the right, and a range of 15° above to 15° below.

[0016] FIG. 3 is a diagram illustrating an example of an illumination area of ​​light emitted by the vehicle headlight of this embodiment. FIG. 3 shows a schematic plan view similar to FIG. 2 described above. The vehicle headlights 1L and 1R are disposed on the left and right sides of the front of the vehicle 100. A reference line c indicated by a dashed dotted line in the figure is a longitudinal axis of the vehicle 100 that extends in the longitudinal direction and passes through the center of the vehicle 100 in the vehicle width direction. A reference line c1 is an axis that is parallel to the reference line c and passes through a predetermined position of the vehicle headlight 1L (for example, approximately the center position of the vehicle headlight 1L in the lateral direction) and extends in the longitudinal direction, and a reference line c2 is an axis that is parallel to the reference line c and passes through a predetermined position of the vehicle headlight 1R (for example, approximately the center position of the vehicle headlight 1L in the lateral direction) and extends in the longitudinal direction.

[0017] As shown in the figure, the lamp 10L of the vehicle headlamp 1L emits a low beam LB ahead of the vehicle 100. The front-illuminating lamp 12L of the front turn lamp 11L emits a flashing light Ta. The flashing light Ta is mainly emitted ahead of the vehicle 100. In the example shown in the figure, the illumination area of ​​the flashing light Ta overlaps with the illumination area of ​​the low beam LB. Although not shown in the figure, the lamp 10L also emits a high beam as appropriate. The side-illuminating lamp 13L of the front turn lamp 11L emits a flashing light Tb to an area extending from the left diagonally forward to the left side of the vehicle 100. Although not shown in the figure, the vehicle headlamp 1R also emits similar low beam, high beam, and flashing light. For example, a low beam or the like having a shape that is approximately symmetrical with respect to the reference line c is emitted.

[0018] In this embodiment, the angle of view of the low beam LB from the lamp 10L ranges from 35° to the left and 35° to the right, measured from the reference line c1. The boundary defining the angle of view of the low beam LB here corresponds to, for example, the boundary between the region where the luminous intensity of the low beam LB is 500 cd or more and the region where it is less than 500 cd. In FIG. 3, this boundary is represented by a solid line to indicate the range of the low beam LB. Although not shown, the angle of view of the low beam from the lamp 10R is also similar, and has a range indicated by an angle measured from the reference line c2.

[0019] The angle of view of the flashing light Ta emitted by the front-illuminating lamp 12L of the front turn lamp 11L is included in the angle of view of the low beam LB (ranging from 35° on the left side to 35° on the right side). The boundary defining the angle of view of the flashing light Ta here corresponds to, for example, the boundary between the area where the luminous intensity of the flashing light Ta is 100 cd or more and the area where it is less than 100 cd. In FIG. 3, this boundary is indicated by a solid line to show the range of the flashing light Ta. Although not shown, the angle of view of the flashing light emitted by the front turn lamp 11R is similar.

[0020] The field angle of the flashing light Tb emitted by the side-illuminating lamp 13L of the front turn lamp 11L is preferably in the range of 70° to 35° leftward and 15° above to 15° below, based on the reference line c1, and more preferably in the range of 70° to 35° leftward and 15° above to 0° (horizontal position). The horizontal position here refers to a horizontal position based on the installation position of the vehicle headlamp 1L (the same applies hereinafter). The boundary defining the field angle of the flashing light Tb corresponds to the boundary between an area where the luminous intensity of the flashing light Tb is equal to or greater than a predetermined value and an area where it is less than the predetermined value. Furthermore, it is preferable that the flashing light Tb has a high luminous intensity (for example, 100 cd or more) in at least a portion of the field angle, and more preferably has a high luminous intensity (for example, 100 cd or more) throughout the entire field angle.

[0021] Although not shown, the angle of view of the flashing light from the side-illuminating lamp 13R of the front turn signal lamp 11R is preferably in the range of 80° to 30° rightward relative to the reference line c2, and in the range of 15° above to 15° below, and more preferably in the range of 80° to 30° rightward relative to the reference line c2, and in the range of 15° above to 0° below. The boundary defining the angle of view of the flashing light corresponds to the boundary between the region where the luminous intensity of the flashing light is equal to or greater than a predetermined value and the region where it is less than the predetermined value. Furthermore, it is preferable that the flashing light has a high luminous intensity (for example, 100 cd or more) in at least a portion of the angle of view, and more preferably has a high luminous intensity (for example, 100 cd or more) throughout the entire angle of view.

[0022] 4 is a diagram illustrating the range illuminated by the flashing light Tb from the side-illuminating lamp 13L of the front turn lamp 11L. FIG. 4 shows the luminous intensity distribution on a virtual screen arranged vertically at a predetermined position ahead of the vehicle (10 m ahead in this example). A rectangular area 110 indicated by a white dotted line in the figure indicates the illumination range of the flashing light Tb, which is set to a range from 70° to 35° leftward and from 15° above to 15° below the reference line c1. The position of the reference line c1 is 0° in the left-right direction.

[0023] As shown in the figure, the illumination range of the flashing light Tb is set to the left of the 35° leftward boundary where the luminous intensity of the low beam LB is less than 500 cd. This region is also the region where the luminous intensity of the flashing light Ta is less than 100 cd. This region is also visible to the driver of the vehicle (see FIG. 2). Therefore, by illuminating this region with the flashing light Tb from the side-illuminating lamp 13L, the amount of light on the left side of the vehicle increases, making it easier to realize that the front turn lamps are on. Furthermore, by making it easier to realize that the front turn lamps are on, it is possible to prevent forgetting to turn them off. Although not shown, the same effect can be achieved with the flashing light from the side-illuminating lamp 13R.

[0024] The rectangular area 111 indicated by the black dotted line in the figure indicates the illumination range of the flashing light Tb, which is set to a range from 70° to 35° to the left and from 15° to 0° (horizontal position) above the reference line c1. Even when the vertical range is narrowed above 0°, the amount of light in the low beam LB's low intensity range can be increased, thereby achieving the same effect as above. In other words, it becomes easier to feel that the front turn signal lamps are on, and it is also possible to prevent forgetting to turn them off. Although not shown in the figure, the same effect can be achieved with the flashing light from the side-illuminating lamps 13R.

[0025] In a more preferred embodiment, the angle of view of the flashing light Tb from the side-illuminating lamp 13L can be in the range of 70° to 35° leftward relative to the reference line c1, and in the range of 5° to 0° upward. Similarly, the angle of view of the flashing light from the side-illuminating lamp 13R can be in the range of 80° to 30° rightward relative to the reference line c2, and in the range of 5° to 0° upward. This can reduce glare on a pedestrian if the pedestrian is within the illumination range of the flashing light.

[0026] Fig. 5 is a diagram for explaining an example of illumination of flashing lights Ta and Tb by the front turn lamp 11L. Fig. 5 also shows the luminous intensity distribution on a virtual screen arranged along the vertical direction at a predetermined position ahead of the vehicle (10 m ahead in this example). In the figure, the line extending left and right at the 0° position in the up-down direction (vertical direction) in the figure corresponds to the horizon, and the line extending up and down at the 0° position in the left-right direction (horizontal direction) in the figure corresponds to the plumb line.

[0027] As shown in the illustrated example, the light emitted by the flashing lights Ta and Tb has a light distribution pattern on the virtual screen that has a first luminous intensity peak 121 near the center where the horizontal line intersects with the vertical line within the front turn light distribution standard range. In the illustrated example, the first luminous intensity peak 121 is the area with the highest luminous intensity within an angular range of 35° or less to the left and right, and is, for example, the area where light of 600 cd or more is emitted.

[0028] Furthermore, the light emitted by the flashing lights Ta and Tb has a second luminous intensity peak 122 at an angle 120 away from the front of the vehicle to the side within the standard range of front turn light distribution as a light distribution pattern on a virtual screen. In the illustrated example, the second luminous intensity peak 122 is the region with the highest luminous intensity within an angular range of 35° to 70° to the left of the reference line c1, and is, for example, a region irradiated with light of 100 cd or more. This second luminous intensity peak 122 can also be considered a continuous luminous intensity band formed to irradiate light of 100 cd or more. The second luminous intensity peak 122 is included within the illumination range of the flashing light Tb emitted by the side-illuminating lamp 13L of the front turn lamp 11L. The preferable conditions for this illumination range are as described above.

[0029] Although not shown, the flashing lights Ta and Tb from the front turn lamp 11R also have the first and second luminous intensity peaks similar to the illumination example shown in FIG.

[0030] According to the first embodiment as described above, it is possible to more easily get the feeling that the turn lamps are on.

[0031] (Second embodiment) In each of the front turn lamps 11L, 11R, when the operation of the side-illuminating lamps 13L, 13R is linked to the forward-illuminating lamps 12L, 12R, the operation of the side-illuminating lamps 13L, 13R may be controlled in consideration of the environment around the vehicle. Note that, below, differences from the first embodiment will be mainly described, and descriptions of other parts will be omitted.

[0032] FIG. 6 is a block diagram illustrating the configuration of a vehicle headlamp according to a second embodiment. The vehicle headlamp according to the second embodiment includes a left headlamp 1L, a right headlamp 1R, a turn signal lever 2, a controller 3, an illuminance sensor 4, and a rain sensor 5. In the second embodiment, a front-illuminating lamp 12L and a side-illuminating lamp 13L are separate components. The front turn signal lamp 11L includes the front-illuminating lamp 12L and the side-illuminating lamp 13L. Similarly, the front-illuminating lamp 12R and the side-illuminating lamp 13R are separate components. The front turn signal lamp 11R includes the front-illuminating lamp 12R and the side-illuminating lamp 13R. These components may be integrated into one unit, as in the first embodiment.

[0033] The controller 3 is realized by executing a predetermined operation program on a computer having, for example, a processor and a memory. The controller 3 has an irradiation control unit (irradiation control function) 30 and an environment estimation unit (environment estimation function) 31 as functional blocks.

[0034] The illumination control unit 30 controls the light illumination state of each of the left headlight 1L and the right headlight 1R based on the operating states of a lamp switch (not shown) and a turn signal lever 2 and the estimation results of the environment estimation unit 31. Specifically, the illumination control unit 30 controls the illumination state of the low beam and high beam of the lamps 10L and 10R based on the operating state of the lamp switch. The illumination control unit 30 also controls the illumination state of the front turn lamps 11L and 11R based on the operating state of the turn signal lever 2. The illumination control unit 30 also controls the illumination state of each of the side-illuminating lamps 13L and 13R based on the operating state of the turn signal lever 2 and the estimation results of the environment estimation unit 31.

[0035] The environment estimation unit 31 estimates whether the illuminance around the vehicle is equivalent to nighttime, based on the illuminance around the vehicle detected by the illuminance sensor 4. The environment estimation unit 31 also estimates whether the amount of rainfall around the vehicle is equivalent to rain, based on the amount of rainfall around the vehicle detected by the rainfall sensor 5. Each estimation result is passed from the environment estimation unit 31 to the irradiation control unit 30.

[0036] Next, the control of the left headlamp 1L and the right headlamp 1R by the controller 3 will be described.

[0037] For example, when the illumination control unit 30 is causing the lamps 10L and 10R to emit low beams or high beams based on the operating state of the lamp switch, it can operate the side illumination lamps 13L and 13R in conjunction with the front illumination lamps 12L and 12R.

[0038] In addition, when the estimation result by the environment estimation unit 31 indicates that it is nighttime, the illumination control unit 30 can operate each of the side illumination lamps 13L, 13R in conjunction with each of the front turn lamps 11L, 11R.

[0039] In addition, when the estimation result by the environment estimation unit 31 indicates that it is rainy weather, the illumination control unit 30 can operate each of the side illumination lamps 13L, 13R in conjunction with each of the front illumination lamps 12L, 12R.

[0040] Furthermore, based on the estimation results of the environment estimation unit 31, the illumination control unit 30 can operate the side illumination lamps 13L, 13R in conjunction with the front illumination lamps 12L, 12R when it is nighttime and raining.

[0041] According to the second embodiment as described above, it is possible to make it easier to realize that the front turn signal lamps are on. In particular, by controlling whether or not the side-illuminating lamps 13L, 13R are activated depending on the surrounding environment of the vehicle, it is possible to selectively activate the side-illuminating lamps 13L, 13R in situations where it is more necessary.

[0042] The present disclosure is not limited to the contents of the above-described embodiments, and various modifications can be made within the scope of the gist of the present disclosure. For example, the above-described embodiments assume that the driver's seat of the vehicle is located on the right side, i.e., the left side is the "first side" and the right side is the "second side." However, the left and right sides may be reversed. That is, the driver's seat may be located on the left side, and the right side may correspond to the "first side" and the left side may correspond to the "second side." In this case, the illumination ranges of the above-described side-illuminating lamps 13L and 13R may be reversed in the left-right direction.

[0043] The high beams in the above-described embodiments may be selective high beams that have a dimming range that is set according to the position of other vehicles in front of the vehicle. The blinking cycles of the blinking lights of the side-illuminating lamps 13L, 13R and the front-illuminating lamps 12L, 12R may be different from each other or may be the same.

[0044] In addition, in the above-described embodiments, the angle of view of the flashing light from the side-illuminating lamp 13L and the angle of view of the flashing light from the side-illuminating lamp 13R are asymmetric in the left-right direction, but they may also be symmetric. As an example, the angle of view of the flashing light from the side-illuminating lamp 13L can be set to a range of 80° to 30° on the left side relative to the reference line c1, and the angle of view of the flashing light from the side-illuminating lamp 13R can be set to a range of 80° to 30° on the right side relative to the reference line c1. In this case, the vertical angle can be set to a range of 15° above to 15° below, as described above, preferably a range of 15° to 0° above, and more preferably a range of 5° to 0° above.

[0045] In addition, in the second embodiment described above, rain was detected using a rainfall sensor, but rain may also be detected based on the operating state of the wiper switch of the vehicle, or based on weather information that can be obtained from outside via wireless communication.

[0046] Furthermore, in each of the above-described embodiments, each front turn lamp 11L, 11R is configured as a separate lamp that emits light in the direction ahead of the vehicle and a separate lamp that emits light to the side of the vehicle, but the lamps may be configured as an integrated unit rather than being separate.

[0047] The present disclosure has the following additional features. (Appendix 1) A front turn lamp disposed adjacent to each of a pair of headlights or integrally with the headlights at the front of a vehicle, The light distribution pattern on the virtual screen of the front turn lamp has a first luminous intensity peak near the center where the horizontal line and the vertical line intersect within the front turn light distribution standard range, and a second luminous intensity peak at an angle position away from the front of the vehicle to the side.
