DETAILED DESCRIPTION OF THE INVENTION

[0009] In order to explain the present disclosure in more detail, embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0010] Embodiment 1 In the first embodiment, a basic form of the present disclosure will be described. An example configuration of a control device according to a first embodiment of the present disclosure will be described.

[0011] FIG. 1 is a diagram illustrating an example of a basic configuration of a control device 100 according to a first embodiment of the present disclosure. The control device 100 controls the illumination range of the lighting device based on the field of view range. The control device 100 can also be expressed as an illumination control device, a light distribution control device, or a light control device. The lighting device is mounted on the moving body and emits light in the moving direction of the moving body in accordance with commands from the control device 100. The mobile body is a means of transportation including a vehicle. The control device 100 shown in FIG. 1 includes a line-of-sight information acquisition unit 110 and an irradiation control unit 200.

[0012] The line-of-sight information acquisition unit 110 acquires the line-of-sight direction of a passenger in a moving body. The gaze direction is, for example, the line of sight or the face direction. The line-of-sight information acquisition unit 110 outputs line-of-sight information indicating the line-of-sight direction of the occupant.

[0013] The illumination control unit 200 issues a command to change the illumination range of the lighting device based on the field of view range derived using the line-of-sight direction acquired by the line-of-sight information acquisition unit. The illumination control unit 200 derives the field of view range expressed as an angle relative to the line of sight using the line of sight direction. The illumination control unit 200 commands the lighting device to change the current illumination range in accordance with the field of view range.

[0014] In addition to the above components, the control device 100 also includes a control unit (not shown), a storage unit (not shown), and a communication unit (not shown). A control unit (not shown) controls the entire control device 100 and each of its components. The control unit (not shown) starts up the control device 100 in accordance with, for example, an external command. The control unit (not shown) also controls the state of the control device 100 (operating state = state such as start-up, shutdown, sleep, etc.). A storage unit (not shown) stores each piece of data used by the control device 100. The storage unit (not shown), for example, stores the output (output data) from each component in the control device 100, and outputs data requested by each component to the component that made the request. The communication unit (not shown) communicates with an external device. For example, communication is performed between the control device 100 (a control device 100A described below) and a peripheral device (e.g., a device mounted on a mobile body). For example, when the control device 100 and the device mounted on a mobile body are not connected by wire, the communication unit (not shown) has a function of communicating between the control device 100 and the device mounted on a mobile body. The communication unit (not shown) may also have a function of communicating with a server device, which is an external device. The control unit (not shown), the storage unit (not shown), and the communication unit (not shown) are the same in the embodiments described below.

[0015] Next, an example of the configuration of a control system including the control device will be described. FIG. 2 is a diagram illustrating an example configuration of a control system 1A including a control device 100A according to the first embodiment of the present disclosure. The control system 1A is a system for controlling lighting devices of a moving body. For example, when the moving body is a vehicle, the control system 1A is a system that controls a headlight unit of the vehicle. The control system 1A shown in FIG. 2 includes a control device 100A, a lighting device 500, and a DMS (Driver Monitoring System) 600.

[0016] The lighting device 500 is mounted on a moving object and emits light in the direction of travel of the moving object. The lighting device 500 is configured to be able to emit a low beam that illuminates a short range of the moving object, such as the area in front of the moving object in the moving direction, and a high beam that illuminates a long distance in the moving direction of the moving object. Furthermore, the lighting device 500 is configured to be able to change the irradiation direction and irradiation range. The structure for changing the irradiation direction and irradiation range may be a physically operated mechanism, or may be a mechanism that changes the irradiation direction and irradiation range by switching on and off a plurality of light sources. Alternatively, it may be configured by combining these.

[0017] The DMS 600 measures the occupants of a vehicle. The DMS 600 detects the line of sight of the occupant of the moving body or the facial direction of the occupant of the moving body and outputs it as line of sight information. The DMS 600 may be configured to detect and output biological information such as the age and physical condition of the vehicle occupant. Additionally, the DMS 600 may be configured to provide personal authentication to vehicle occupants.

[0018] The control device 100A has the same configuration as the control device 100 already described, and includes a line-of-sight information acquisition unit 110A and an irradiation control unit 200A.

[0019] The line-of-sight information acquisition unit 110A has the same configuration as the line-of-sight information acquisition unit 110 already described, and acquires the line-of-sight information output by the DMS600.

[0020] The illumination control unit 200A is configured in the same manner as the illumination control unit 200 already described, and commands the lighting device 500 to change the current illumination range in accordance with the field of view range.

[0021] FIG. 3 is a diagram illustrating the relationship between the line of sight, the field of view, and the illumination range in the present disclosure. Figure 3 shows the range of the central field of view 1040 based on the line of sight 1030, the range of the effective field of view 1050, the range illuminated by the low beam 1010, and the range illuminated by the high beam 1020 (1020a, 1020b) (illumination range) when the moving body is a vehicle 1000 and the line of sight 1030 of the driver, who is an occupant of the vehicle 1000, is the same as the direction of travel of the vehicle 1000. The range of the central visual field 1040 and the range of the effective visual field 1050 can be expressed as a value such as an angle relative to the line of sight 1030.

[0022] Next, an image of how the irradiation range changes under the control of the control device will be explained. FIG. 4 is a diagram illustrating an image of a change in the irradiation range under the control of the control device 100A according to the first embodiment of the present disclosure. 4 shows a state in which the line of sight 1030 of the driver of vehicle 1000 has moved to the right in the direction of travel. In this state, control device 100A changes the illumination range by moving it to the right (right diagram in FIG. 4) when the edge that is the boundary of the field of view (effective field of view 1050 in the example of FIG. 4) set based on line of sight 1030 overlaps with the edge of the illumination range of high beam 1020 (left diagram in FIG. 4).

[0023] Next, an example of processing by the control device according to this embodiment will be described. The processing of the control device 100 and the control device 100A differs in that the control device 100A can clearly indicate the source of the information used in the processing and can clearly indicate that the control destination is the lighting device 500. However, since the internal processing is similar, an example of the processing of the control device 100A will be described here as a representative.

[0024] FIG. 5 is a flowchart showing an example of processing by the control device 100A according to the first embodiment of the present disclosure. The process shown in Fig. 5 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100A shown in Fig. 2 receives information from an external or internal control unit (not shown), it starts the processing shown in Fig. 5. Specifically, for example, the control device 100 or the control device 100A starts the processing shown in Fig. 5 when the lighting device 500 starts illumination or while illumination is in progress.

[0025] Next, the control device 100A executes a line-of-sight information acquisition process (step ST1100). In the line-of-sight information acquisition process, the line-of-sight information acquisition unit 110A of the control device 100A acquires the line-of-sight direction of the occupant in the moving body. The line-of-sight information acquiring unit 110A acquires the line-of-sight information output by the DMS 600. The line-of-sight information acquiring unit 110A outputs the line-of-sight information to the irradiation control unit 200A.

[0026] The control device 100A then executes irradiation control processing (step ST1200). In the illumination control process, the illumination control unit 200A of the control device 100A issues a command to change the illumination range of the lighting device 500 based on the field of view range derived using the acquired line of sight direction. The illumination control unit 200A acquires the line-of-sight information output by the line-of-sight information acquisition unit 110A. The illumination control unit 200A estimates and sets the field of view using the line-of-sight direction included in the line-of-sight information. The illumination control unit 200A sets the field of view range by adding a pre-stored angle to the line of sight direction, for example. The pre-stored angle is not particularly limited in this embodiment, but when setting the range of the effective field of view, it is a fixed angle of, for example, 20 to 30 degrees per eye. Furthermore, the irradiation control unit 200A may adjust the angle, for example, as in the embodiment described later.

[0027] Next, the control device 100A executes an end determination process (step ST1300). In the termination determination process, a control unit (not shown) of the control device 100A determines whether to terminate the processing of the control device 100A. The control unit (not shown) determines whether to terminate the processing of the control device 100A in accordance with, for example, an external termination command or an execution program. When the control unit (not shown) determines not to end the processing of the control device 100A ("NO" in step ST1300), the process proceeds to step ST1100, and the process is repeated from step ST1100. When the control unit (not shown) determines that the processing of the control device 100A is to be ended ("YES" in step ST1300), the control device 100A ends the processing.

[0028] According to the configuration of this embodiment, the control device changes the illumination range based on the visual field range of the occupant of the mobile body, so it is possible to shorten the time until illumination in the direction of the occupant's actual line of sight when the occupant's line of sight moves. Since it is possible to shorten the time until illumination in the direction of the occupant's actual line of sight when the occupant's line of sight moves, it is possible to suppress delays in illumination in the direction the occupant of the mobile body is trying to look.

[0029] This embodiment shows an example of the following configuration. a line-of-sight information acquisition unit for acquiring a line-of-sight direction of a passenger in a moving body; an illumination control unit that commands the lighting device to change an illumination range based on a field of view range derived using the line-of-sight direction acquired by the line-of-sight information acquisition unit; A control device comprising: As a result, the present disclosure has the effect of providing a control device that makes it possible to suppress delays in illumination of the range that an occupant of a moving body is trying to see.

[0030] This embodiment shows an example of the following configuration.

[0031] This embodiment shows an example of the following configuration. Computer, a line-of-sight information acquisition unit for acquiring a line-of-sight direction of a passenger in a moving body; an illumination control unit that changes an illumination range of the lighting device based on a field of view range derived using the line-of-sight direction acquired by the line-of-sight information acquisition unit; and operating the controller as a controller comprising: A program characterized by: As a result, the present disclosure has the effect of providing a program that makes it possible to suppress delays in illumination of the range that an occupant of a moving body is trying to see.

[0032] Embodiment 2 The second embodiment will explain a more detailed example of the configuration according to the first embodiment. In embodiment 2, among the components of embodiment 2, components that are similar to the components of embodiment 1 already described are given the same names and similar symbols (with some modifications), and duplicate explanations are omitted as appropriate.

[0033] A configuration example of a control device according to a second embodiment of the present disclosure and a control system including the device will be described. FIG. 6 is a diagram illustrating an example configuration of a control system 1B including a control device 100B according to the second embodiment of the present disclosure.

[0034] The control system 1B includes a control device 100B, a lighting device 500, and a DMS600. The lighting device 500 is configured in the same manner as the lighting device 500 already described. The DMS 600 is configured similarly to the DMS 600 already described.

[0035] The control device 100B shown in FIG. 6 includes a line-of-sight information acquisition unit 110B, an illumination range acquisition unit 120B, and an illumination control unit 200B. The line-of-sight information acquisition unit 110B has the same configuration as the line-of-sight information acquisition unit 110B already described.

[0036] The illumination range acquisition unit 120B acquires the current illumination range of the lighting device 500. The illumination range is indicated, for example, by an angle relative to the traveling direction of the mobile object.

[0037] The illumination control unit 200B issues a command to change the illumination range of the lighting device based on the visual field range that is likely to be the effective visual field derived using the line-of-sight direction acquired by the line-of-sight information acquisition unit. The illumination control unit 200B shown in FIG. 6 includes a field of view range setting unit 210B, a light distribution change determining unit 220B, a light distribution shape determining unit 280B, and a light distribution command unit 290B.

[0038] The visual field range setting unit 210B sets the visual field range of the passenger of the moving body. The visual field range setting unit 210B derives a visual field range that is likely to be the range of the occupant's effective visual field using the line of sight direction. The visual field range that is likely to be the range of the occupant's effective visual field is preferably set to, for example, a range of 20 to 30 degrees per eye, and a range of 40 to 60 degrees for both eyes. The visual field range that is likely to be the range of the occupant's effective visual field can also be expressed as an estimated effective visual field range. The field of view range setting unit 210B sets the field of view range by adding a pre-stored angle as a margin to the angle indicating the line of sight direction. The visual field range setting unit 210B outputs visual field range information indicating the angle relative to the line of sight, which is the visual field range. The angle relative to the line of sight, which is the visual field range, indicates the boundary or edge of the visual field.

[0039] The light distribution change determining unit 220B determines whether to change the illumination range. Light distribution change determination unit 220B uses the field of view range and the illumination range to determine whether to change the illumination range. The light distribution change determination unit 220B determines whether to change the illumination range based on the result of comparison between the field of view range and the illumination range. Light distribution change determination unit 220B converts the field of view angle indicating the field of view range and the illumination angle indicating the illumination range so that they can be compared, and determines whether to change the illumination range using the angle difference between the converted field of view angle and the converted illumination angle.

[0040] The light distribution pattern determining unit 280B determines the light distribution pattern of the light to be emitted by the lighting device 500. Light distribution pattern determination section 280B determines the light distribution pattern based on the determination result by light distribution change determination section 220B. Light distribution shape determination unit 280B determines a light distribution shape using the determination result by light distribution change determination unit 220B and the comparison result between the field of view range and the illumination range. For example, when light distribution shape determination unit 280B determines that the field of view range deviates from the illumination range, it determines a light distribution shape that expands the illumination range to its maximum, or a light distribution shape that expands the illumination range to a preset range. Alternatively, when light distribution shape determination unit 280B determines that the field of view range deviates from the illumination range, it determines a light distribution shape that expands the illumination range to its maximum, or a light distribution shape that expands the illumination range to a preset range. Note that light distribution pattern determining section 280B may determine the light distribution pattern using, for example, the angular difference between the viewing angle and the illumination angle.

[0041] Light distribution pattern determination unit 280B expands the illumination range in the movement direction, which is the direction in which the field of view range has moved. The image of how the irradiation range changes under the control of the control device 100B in this case will be described. FIG. 7 is a diagram showing a first image of change in the irradiation range under the control of the control device 100B according to the second embodiment. The left diagram in Figure 7 shows a state in which the line of sight 1030 of the driver of vehicle 1000 has moved to the right in the direction of travel of vehicle 1000. In this state, control device 100B changes the illumination range by moving it to the right when the edge of the boundary of the field of view (effective field of view 1050 in the example of Figure 7) set based on line of sight 1030 overlaps with the edge of the illumination range of high beam 1020a (single-sided arrow A in Figure 7). The right diagram of Fig. 7 shows a state in which the line of sight 1030 of the driver of vehicle 1000 has moved leftward in the traveling direction of vehicle 1000 from the state shown in the left diagram of Fig. 7. In this state, control device 100B changes the illumination range by moving it to the left when the edge of the boundary of the field of view (effective field of view 1050 in the example of Fig. 7) set based on line of sight 1030 overlaps with the edge of the illumination range of high beam 1020a (single-sided arrow B in Fig. 7). In this case, the control device 100B changes the irradiation range twice in response to the left and right movement of the field of view.

[0042] Alternatively, light distribution pattern determination section 280B expands the illumination range in both the movement direction in which the field of view range has moved and the opposite direction to the movement direction. The image of how the irradiation range changes under the control of the control device 100B in this case will be described. FIG. 8 is a diagram showing a second image of change in the irradiation range under the control of the control device 100B according to the second embodiment. The left diagram in Figure 8 shows a state in which the line of sight 1030 of the driver of vehicle 1000 has moved to the right in the direction of travel of vehicle 1000. In this state, when the edge of the boundary of the field of view (effective field of view 1050 in the example of Figure 8) set based on line of sight 1030 overlaps with the edge of the illumination range of high beam 1020a, control device 100B changes the illumination range by expanding it to the right as well as to the left (double arrow C in Figure 8). The right diagram of Fig. 8 shows a state in which the line of sight 1030 of the driver of the vehicle 1000 has moved leftward in the traveling direction of the vehicle 1000 from the state shown in the left diagram of Fig. 8. Because the control device 100B has already expanded the illumination range to the left as well as to the right, it is no longer necessary to change the illumination range by moving it to the left. In this case, the control device 100B changes the irradiation range only once even if the field of view moves left or right. This reduces the number of times that the occupant has to check left and right, making it possible to perform efficient control.

[0043] The light distribution command unit 290B issues a command to the lighting device 500 based on the light distribution pattern. The light distribution command unit 290B outputs a control signal to command the lighting device 500 to irradiate light in the light distribution pattern determined by the light distribution pattern determination unit 280B.

[0044] Next, a processing example of the control device according to the second embodiment of the present disclosure will be described. FIG. 9 is a flowchart showing an example of processing by the control device 100B according to the second embodiment of the present disclosure. The process shown in Fig. 9 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100B shown in Fig. 6 receives a command from an external or internal control unit (not shown), it starts the process shown in Fig. 9. Specifically, for example, the control device 100B starts the process shown in Fig. 9 when the lighting device 500 starts illuminating or while the lighting device 500 is illuminating.

[0045] Next, control device 100B executes irradiation range acquisition processing (step ST2100). In the illumination range acquisition process, the illumination range acquisition unit 120B of the control device 100B acquires the current illumination range of the lighting device 500. The illumination range acquisition unit 120B may acquire illumination range information indicating the illumination range from the lighting device 500, or may acquire illumination range information indicating the illumination range from inside the control device 100B. Illumination range acquisition unit 120B outputs illumination range information to light distribution change determination unit 220B.

[0046] Control device 100B then executes line-of-sight information acquisition processing (step ST2200). In the line-of-sight information acquisition process, line-of-sight information acquisition unit 110B of control device 100B acquires line-of-sight information from DMS 600. Line-of-sight information acquisition unit 110B outputs the acquired line-of-sight information to visual field range setting unit 210B.

[0047] Control device 100B then executes a field-of-view range setting process (step ST2300). In the visual field range setting process, the visual field range setting unit 210B of the illumination control unit 200B in the control device 100B derives a visual field range that is likely to be the range of the occupant's effective visual field using the line of sight direction. The visual field range setting unit 210B acquires the line of sight information from the line of sight information acquisition unit 110B. The visual field range setting unit 210B sets the visual field range by adding a pre-stored angle as a margin to the angle indicating the visual line direction included in the visual line information. The visual field range setting unit 210B outputs visual field range information indicating the visual field range to the light distribution change determination unit 220B.

[0048] Control device 100B then executes a process for determining a change in light distribution (step ST2400). In the light distribution change determination process, the light distribution change determination unit 220B of the illumination control unit 200B in the control device 100B uses the field of view range and the illumination range to determine whether to change the illumination range. Light distribution change determination unit 220B converts the angle indicating the field of view range and the angle indicating the illumination range so that they can be compared, and determines whether to change the light distribution based on the comparison result indicating whether the field of view range and the illumination range overlap. When light distribution change determination section 220B determines that the light distribution (irradiation range) should be changed, it outputs the determination result and the comparison result to light distribution pattern determination section 280B.

[0049] Control device 100B then executes a light distribution pattern determination process (step ST2500). In the light distribution pattern determination process, the light distribution pattern determination unit 280B of the illumination control unit 200B in the control device 100B determines the light distribution pattern using the comparison result output by the light distribution change determination unit 220B. The light distribution pattern determination unit 280B outputs light distribution information indicating the light distribution pattern to the light distribution command unit 290B.

[0050] Next, control device 100B executes a light distribution command process (step ST2600). In the light distribution command processing, the light distribution command section 290B of the irradiation control section 200B in the control device 100B outputs a control signal to command the lighting device 500 to emit light in the light distribution pattern indicated in the light distribution information.

[0051] After executing the light distribution command process in step ST2600, the control device 100B then executes an end determination process (step ST2700). In the termination determination process, a control unit (not shown) of the control device 100B determines whether to terminate the processing of the control device 100B. The control unit (not shown) determines whether to terminate the processing of the control device 100B in accordance with, for example, an external termination command or an execution program. When the control unit (not shown) determines not to end the processing of the control device 100B ("NO" in step ST2700), the control unit 100B moves to the processing of step ST2100 and repeats the processing from step ST2100. When the control unit (not shown) determines that the processing of the control device 100B should be ended ("YES" in step ST2700), the control device 100B ends the processing.

[0052] According to the configuration of this embodiment, the control device changes the illumination range based on the estimated effective visual field range of the occupant of the mobile body, so it is possible to shorten the time until illumination in the direction of the occupant's actual line of sight when the occupant's line of sight moves. Since it is possible to shorten the time until illumination in the direction of the occupant's actual line of sight when the occupant's line of sight moves, it is possible to suppress delays in illumination in the direction the occupant of the mobile body is trying to look. Furthermore, since the illumination range is set to a range that is likely to be visible to the occupant, it is possible to avoid unnecessary illumination and set the illumination range efficiently.

A control device characterized by: As a result, the present disclosure has the effect of providing a control device that makes it possible to reduce the number of times the illumination range is changed, for example, when the occupant is in a situation where he or she is checking alternately left and right. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to a control system, the above control method, or the above program. Furthermore, the configuration of the present disclosure can be applied to all of the embodiments of the present invention, and provides the same effects as those described above.

[0055] Embodiment 3 In the third embodiment, a mode will be described in which the illumination range is changed using the field of view range taking into consideration the speed of a moving object. In embodiment 3, among the components of embodiment 3, those components that are similar to the components of embodiment 1 or embodiment 2 already described are given the same names and similar symbols (with some modifications), and duplicate explanations are omitted as appropriate.

[0056] A configuration example of a control device according to a third embodiment of the present disclosure and a control system including the device will be described. FIG. 10 is a diagram illustrating a configuration example of a control system 1C including a control device 100C according to the third embodiment of the present disclosure. The control system 1C shown in FIG. 10 includes a control device 100C, a lighting device 500, a DMS 600, and an ECU (Electronic Control Unit) 700. The lighting device 500 is configured in the same manner as the lighting device 500 already described. The DMS 600 is configured similarly to the DMS 600 already described.

[0057] The ECU 700 is mounted on a moving object and outputs moving object information including the moving object's speed and other progress status. When the moving object is a vehicle, the ECU 700 outputs vehicle information including the vehicle speed.

[0058] The control device 100C includes a line-of-sight information acquisition unit 110C, an irradiation range acquisition unit 120C, a moving object information acquisition unit 130C, and an irradiation control unit 200C. The line-of-sight information acquisition unit 110C is configured in the same manner as the line-of-sight information acquisition unit 110 already described. The illumination range acquisition unit 120C has the same configuration as the illumination range acquisition unit 120 already described.

[0059] The mobile body information acquisition unit 130C acquires mobile body information. Mobile object information acquisition unit 130C acquires mobile object information output by ECU 700, including the progress status of the mobile object, such as the speed of the mobile object.

The irradiation control unit 200C includes a field of view range setting unit 210C, a light distribution change determining unit 220C, a light distribution shape determining unit 280C, and a light distribution command unit 290C. Light distribution change determining section 220C, light distribution shape determining section 280C, and light distribution command section 290C are configured in substantially the same manner as the components of the same names already described, and therefore description thereof will be omitted.

[0061] The visual field range setting unit 210C derives a visual field range that is likely to be the range of the occupant's effective visual field using the line of sight direction. The visual field range setting unit 210C uses the line of sight direction and the moving body information to derive the visual field range according to the progress of the moving body. The visual field range setting unit 210C shown in FIG. 10 includes a margin estimation unit 211 and an effective visual field angle setting unit 212.

[0062] The margin estimation unit 211 estimates the margin according to the moving object speed included in the moving object information. Specifically, the margin estimation unit 211 estimates the angle of the margin to be smaller as the moving object speed increases, and to be larger as the moving object speed decreases, based on the idea that the effective field of view narrows depending on the speed.

[0063] The effective viewing angle setting unit 212 sets the effective viewing angle using the margin estimated by the margin estimation unit 211 . The effective viewing angle setting unit 212 sets the effective viewing angle so that the faster the moving object speed is, the narrower the effective viewing angle is by adding a smaller angle as a margin to the line of sight, and the slower the moving object speed is, the wider the effective viewing angle is by adding a larger angle as a margin to the line of sight. The set effective viewing angle is expressed, for example, in the form of a plus or minus angle relative to the case where the speed is 0.

[0064] Next, a processing example of the control device according to the third embodiment of the present disclosure will be described. FIG. 11 is a flowchart showing an example of processing by the control device 100C according to the third embodiment of the present disclosure. The process shown in Fig. 11 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100C shown in Fig. 10 receives a command from an external or internal control unit (not shown), it starts the processing shown in Fig. 11. Specifically, for example, the control device 100C starts the processing shown in Fig. 11 when the lighting device 500 starts illuminating or while the lighting device 500 is illuminating.

[0065] Control device 100C then executes moving object information acquisition processing (step ST3100). In the moving body information acquisition process, moving body information acquisition unit 130C of control device 100C acquires the moving body information output by ECU 700. Moving body information acquisition unit 130C outputs the moving body information to visual field range setting unit 210C.

[0066] Control device 100C then executes margin angle estimation processing (step ST3200). In the margin angle estimation process, margin estimation unit 211 of field of view range setting unit 210C in control device 100C estimates the margin angle using moving object information. The margin angle is an angle that is added to the line of sight direction as described above to set the field of view range. The margin estimation unit 211 outputs the margin angle to the effective viewing angle setting unit 212 .

[0067] Control device 100C then executes an effective viewing angle setting process (step ST3300). In the effective viewing angle setting process, effective viewing angle setting unit 212 of viewing range setting unit 210C in control device 100C sets the effective viewing angle by adding a margin angle to the viewing direction included in the viewing information, using the margin angle output by margin estimation unit 211 and the viewing information output by viewing information acquisition unit 110C. The effective viewing angle indicates the range of the effective field of view.

[0068] Control device 100C then executes a field-of-view range output process (step ST3400). In the visual field range output process, the visual field range setting unit 210C of the irradiation control unit 200C in the control device 100C outputs visual field range information including the effective viewing angle to the light distribution change determination unit 220C. As a result, the processing after the light distribution change determination unit 220 (220C) already described is performed using the visual field range information including the effective visual field angle.

[0069] Next, the visual field range setting unit 210C of the control device 100C ends the series of processes shown in FIG.

Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to a control system, the above control method, or the above program. Furthermore, the configuration of the present disclosure can be applied to all of the embodiments of the present invention, and provides the same effects as those described above.

[0072] Embodiment 4 In the fourth embodiment, an embodiment in which the output level can be adjusted depending on the irradiation range will be described. In embodiment 4, among the components of embodiment 4, those components that are similar to the components of embodiment 1, embodiment 2, or embodiment 3 already described are given the same names and similar symbols (with some modifications), and duplicate explanations are omitted as appropriate.

[0073] A configuration example of a control device according to a fourth embodiment of the present disclosure and a system including the device will be described. FIG. 12 is a diagram illustrating a configuration example of a control system 1D including a control device 100D according to the fourth embodiment of the present disclosure. The control system 1D shown in FIG. 12 includes a control device 100D, a lighting device 500, a DMS 600, and an ECU 700. The lighting device 500, the DMS 600, and the ECU 700 are configured in substantially the same manner as the components of the same names that have already been described, and therefore description thereof will be omitted.

[0074] The control device 100D adjusts the output level in accordance with the irradiation range in addition to the functions of the control device 100 (100B, 100C) already described. The control device 100D includes a line-of-sight information acquisition unit 110D, an illumination range acquisition unit 120D, a moving object information acquisition unit 130D, and an illumination control unit 200D. The line-of-sight information acquisition section 110D, the illumination range acquisition section 120D, and the moving object information acquisition section 130D are configured in substantially the same manner as the components of the same names already described, and therefore description thereof will be omitted.

[0075] The illumination control unit 200D controls the illumination of the lighting device 500 so as to adjust the output level of the light to be illuminated according to the illumination range. The irradiation control unit 200D includes a field of view range setting unit 210D, a light distribution change determining unit 220D, an output adjusting unit 230D, a light distribution shape determining unit 280D, and a light distribution command unit 290D. The visual field range setting section 210D and the light distribution change determining section 220D are configured in substantially the same manner as the components of the same names already explained, and therefore explanations thereof will be omitted. Moreover, the margin estimation section 211 and the effective viewing angle setting section 212 in the viewing field range setting section 210D are configured in substantially the same manner as the components of the same names already explained, and therefore explanations thereof will be omitted.

[0076] In addition to the functions of light distribution pattern determination unit 280 (280C) already described, light distribution pattern determination unit 280D notifies output adjustment unit 230D of the light distribution pattern.

[0077] The output adjustment unit 230D adjusts the output level of the light to be emitted depending on the irradiation range. Output adjustment unit 230D determines whether the illumination range should be expanded toward the oncoming lane based on the light distribution pattern output by light distribution pattern determination unit 280D. If the illumination range should be expanded toward the oncoming lane, output adjustment unit 230D outputs adjustment information to instruct adjustment to lower the output level of the irradiated light. When the illumination range is indicated by the illumination angle, the output adjustment unit 230D adjusts the output level of the irradiated light to decrease when the illumination angle is to be widened in the direction of the oncoming lane. This makes it possible to reduce glare to oncoming vehicles (one example of a moving body traveling in the opposite direction).

[0078] The light distribution command unit 290D adjusts the output level of the light to be emitted in accordance with the illumination range based on the command from the output adjustment unit 230D, and commands the lighting device 500 to emit light at the adjusted output level.

[0079] Next, a processing example of the control device according to the fourth embodiment of the present disclosure will be described. FIG. 13 is a flowchart showing an example of processing by the control device 100D according to the fourth embodiment of the present disclosure. The process shown in Fig. 13 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100D shown in Fig. 12 receives a command from an external or internal control unit (not shown), it starts the processing shown in Fig. 13. Specifically, for example, the control device 100D starts the processing shown in Fig. 13 when the lighting device 500 starts illuminating or while the lighting device 500 is illuminating.

[0080] Control device 100D then executes irradiation range expansion determination processing (step ST4100 "Is irradiation range expanded?"). In the irradiation range expansion determination process, the output adjustment unit 230D of the irradiation control unit 200D in the control device 100D acquires light distribution shape information indicating the light distribution shape notified by the light distribution shape determination unit 280D, and determines whether the irradiation range will expand toward the oncoming lane based on the light distribution shape indicated in the light distribution shape information.

[0081] If the illumination range is to be expanded toward the oncoming lane (step ST4100 "Expand illumination range?" "YES"), output adjustment unit 230D then determines to reduce the output level (step ST4200 "Low output level").

[0082] If the illumination range does not expand toward the oncoming lane (step ST4100 "Is illumination range expanded?" "NO"), the output adjustment unit 230D of the illumination control unit 200D in the control device 100D then executes an illumination range reduction determination process (step ST4300 "Is illumination range reduced?"). In the irradiation range reduction determination process, the output adjustment unit 230D of the irradiation control unit 200D in the control device 100D determines whether the irradiation range will be reduced. If it is determined that the irradiation range will not be reduced (step ST4300 "Irradiation range reduced?" "NO"), output adjustment unit 230D ends the process shown in FIG.

[0083] If output adjustment unit 230D determines that the irradiation range will be reduced (step ST4300 "Irradiation range reduced?" "YES"), it then determines to return the output level to normal (step ST4400 "output level normal").

[0084] Control device 100D then executes an adjustment signal output process (step ST4500). When the output adjustment unit 230D of the irradiation control unit 200D in the control device 100D determines that the output level should be reduced (step ST4200 ``output level low''), in the adjustment signal output process, it outputs adjustment information to the light distribution command unit 290D to instruct the light distribution control unit 200D to adjust the output level of the light to be irradiated to be reduced. When the output adjustment unit 230D of the irradiation control unit 200D in the control device 100D determines that the output level should be returned to normal (step ST4400 ``output level normal''), in the adjustment signal output process, it outputs adjustment information to the light distribution command unit 290D to instruct the output level of the irradiated light to be returned to normal.

[0085] After outputting the adjustment signal, the output adjustment section 230D of the irradiation control section 200D in the control device 100D then ends the processing shown in FIG.

[0086] According to the configuration of this embodiment, the control device can adjust the output level according to the light irradiation range. When the light irradiation range is expanded toward the oncoming lane, the control device can suppress glare by lowering the output level.

The lighting device 500 and the ECU 700 are configured in substantially the same manner as the components of the same names already described, and therefore a description thereof will be omitted.

[0091] In addition to the functions of the DMS 600 already described, the DMS 600 outputs biological information of the occupant to the control device 100E. The occupant's biological information includes information indicating the occupant's age or information regarding the occupant's physical condition.

[0095] The first change condition adjusting section 240E adjusts the conditions for changing the irradiation range according to the age or physical condition of the occupant indicated by the biological information. Specifically, for example, the first change condition adjusting unit 240E adjusts the timing of changing the illumination range so that it becomes earlier as the age of the occupant increases. Alternatively, the first change condition adjusting unit 240E may adjust the illumination range so that it becomes wider as the age of the occupant increases. Specifically, for example, the first change condition adjusting unit 240E may adjust the timing of changing the illumination range earlier when it is determined that the occupant's physical condition is not good.Furthermore, the first change condition adjusting unit 240E may adjust the illumination range to be wider when it is determined that the occupant's physical condition is not good. The first change condition adjusting section 240E outputs first change condition information, which is a condition for changing the irradiation range, according to the state of the occupant that can be determined based on the biological information.

[0096] In addition to the functions of light distribution shape determination section 280 (280D) already described, light distribution shape determination section 280E determines a light distribution shape in accordance with the change conditions indicated in the first change condition information based on the first change condition information output by first change condition adjustment section 240E. Specifically, for example, the light distribution pattern determination unit 280E advances the timing for changing the irradiation range based on the first change condition information. Or, specifically, for example, the light distribution pattern determination unit 280E changes the size of the illumination range based on the first change condition information.

[0097] The light distribution command unit 290E issues a light distribution command to the lighting device 500 in accordance with the light distribution shape information output by the light distribution shape determination unit 280E.

[0098] Next, a processing example of the control device according to the fifth embodiment of the present disclosure will be described.

The process shown in Fig. 15 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100E shown in Fig. 14 receives information from an external or internal control unit (not shown), it starts the processing shown in Fig. 15. Specifically, for example, the control device 100E starts the processing shown in Fig. 15 when illumination by the lighting device 500 starts or while illumination is being caused.

[0099] Next, the control device 100E executes a biological information acquisition process (step ST5100). In the biometric information acquisition process, the biometric information acquisition unit 150E of the control device 100E acquires the biometric information of the occupant of the moving object output by the DMS 600. The biometric information acquisition unit 150E outputs the biometric information to the first change condition adjustment unit 240E.

[0100] Control device 100E then executes a first change condition adjustment process (step ST5200).

The first change condition adjustment unit 240E adjusts the conditions for changing the irradiation range according to the age or physical condition of the occupant indicated in the biological information.

[0101] Control device 100E then executes an adjustment process (step ST5300). In the adjustment process, the light distribution pattern determination unit 280E of the illumination control unit 200E in the control device 100E acquires the first change condition information output by the first change condition adjustment unit 240E. The light distribution pattern determination unit 280E performs adjustment based on the first change condition information output by the first change condition adjustment unit 240E. The light distribution pattern determination unit 280E adjusts the change timing, which is the timing for changing the illumination range, or the size of the illumination range to be changed. After the adjustment, light distribution pattern determination unit 280E outputs light distribution pattern information indicating the light distribution pattern to light distribution command unit 290E.

[0102] After light distribution pattern determination unit 280E executes the adjustment process, control device 100E then executes an end determination process (step ST5400). In the termination determination process, a control unit (not shown) of the control device 100E determines whether to terminate the processing of the control device 100E. The control unit (not shown) determines whether to terminate the processing of the control device 100E in accordance with, for example, an external termination command or an execution program. When a control unit (not shown) determines not to end the processing of the control device 100E ("NO" at step ST5400), the control device 100E goes to the processing at step ST5100 and repeats the processing from step ST5100. When the control unit (not shown) determines that the process of the control device 100E should be ended ("YES" in step ST5400), the control device 100E ends the process.

[0107] The input / output device 800 is communicably connected to the control device 100F. The input / output device 800 is, for example, a display device with a touch panel. The input / output device 800 may be in the form of a mobile terminal device.

[0108] The control device 100F outputs an operation image for receiving, from the user, a change condition that is a condition for changing the irradiation range. The control device 100F also receives the change condition that is a condition for changing the irradiation range via the operation image and adjusts the change condition. The control device 100F shown in FIG. 16 includes a line-of-sight information acquisition unit 110F, an irradiation range acquisition unit 120F, a moving object information acquisition unit 130F, a biological information acquisition unit 150F, and an irradiation control unit 200F. The line-of-sight information acquisition unit 110F, irradiation range acquisition unit 120F, moving body information acquisition unit 130F, and biometric information acquisition unit 150F are configured in almost the same manner as the components of the same names already described, and therefore description thereof will be omitted.

[0109] The illumination control unit 200F adjusts the conditions for changing the illumination range based on the change conditions received from the user via the operation image. The illumination control unit 200F includes a field of view range setting unit 210F (margin estimation unit 211, effective field of view angle setting unit 212), a light distribution change determination unit 220F, an output adjustment unit 230F, a first change condition adjustment unit 240F, a change condition reception unit 250F, a second change condition adjustment unit 260F, a light distribution shape determination unit 280F, and a light distribution command unit 290F.

[0110] The change condition receiving unit 250F outputs an image for operation to receive a change condition that is a condition for changing the irradiation range. The change condition is, for example, a condition for the timing at which the irradiation state is changed. Alternatively, the change condition may be, for example, a condition regarding the width of the irradiation range to be changed. Alternatively, the change condition may be a condition regarding the timing for changing the illumination state and a condition regarding the width of the illumination range to be changed. FIG. 17 is a diagram showing an example of an operation area where a control device 100F according to the sixth embodiment accepts an input operation. FIG. 17 shows an operation image 6000, which is a user interface for accepting change conditions. 17 displays the timing of expansion as being selectable, whether it is early, standard, or late. Also, the operation image 6000 displays the timing of returning to the original state after expansion as being selectable, whether it is early, standard, or late. This allows for adjustments to personal preference. The operation image 6000 shown in FIG. 17 shows a form in which selection operations are accepted, but it may also be a form in which numerical input is accepted.

[0111] The second change condition adjustment section 260F adjusts the change condition, which is a condition for changing the irradiation range, based on the change condition received via the operation image. Specifically, for example, the second change condition adjustment unit 260F adjusts the timing for changing the illumination by the lighting device based on the change condition received via the operation image. More specifically, for example, the second change condition adjustment unit 260F adjusts the illumination range to be changed by the lighting device based on the change condition received via the operation image.

[0112] Returning to the explanation of FIG. Light distribution pattern determination section 280F determines a light distribution pattern based on the change conditions adjusted by second change condition adjustment section 260F, in addition to the functions of light distribution pattern determination section 280 (280E) already described. Specifically, for example, light distribution pattern determination unit 280F outputs light distribution pattern information indicating the light distribution pattern according to the change timing or the irradiation range to be changed, which are the change conditions.

[0113] The light distribution command unit 290F outputs a control signal to command the light device 500 to distribute light in accordance with the light distribution shape information output by the light distribution shape determination unit 280F.

[0114] Next, a processing example of the control device according to the sixth embodiment of the present disclosure will be described. FIG. 18 is a flowchart showing an example of processing by the control device 100F according to the sixth embodiment of the present disclosure. The process shown in Fig. 18 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100F shown in Fig. 16 receives information from an external or internal control unit (not shown), it starts the processing shown in Fig. 18. Specifically, for example, when the control device 100F receives a change condition setting request from an external user operation, it starts the processing shown in Fig. 18.

[0115] The illumination control unit 200F in the control device 100F then executes an operation image output process (step ST6100). In the operation image output process, the change condition receiving unit 250F of the illumination control unit 200F outputs an operation image for receiving a change condition, which is a condition for changing the illumination range.

[0116] The irradiation control unit 200F in the control device 100F then executes a change condition receiving process (step ST6200). In the change condition reception process, the change condition reception unit 250F of the irradiation control unit 200F receives the change condition via the operation image, and outputs second change condition information indicating the change condition received via the operation image to the second change condition adjustment unit 260F.

[0117] The irradiation control unit 200F in the control device 100F then executes a second change condition adjustment process (step ST6300). In the second change condition adjustment process, the second change condition adjustment unit 260F of the irradiation control unit 200F acquires the second change condition information output by the change condition reception unit 250F. Based on the second change condition information, the second change condition adjustment section 260F outputs adjustment information for adjusting the change condition, which is a condition for changing the irradiation range, to the light distribution pattern determination section 280F.

[0118] The irradiation control unit 200F in the control device 100F then executes an adjustment process (step ST6400). In the adjustment process, the light distribution pattern determination unit 280F of the illumination control unit 200F acquires the second change condition information output by the second change condition adjustment unit 260F. The light distribution pattern determination unit 280F performs adjustment based on the change conditions indicated in the second change condition information. The light distribution pattern determination unit 280F adjusts the change timing, which is the timing for changing the illumination range, or the size of the illumination range to be changed. After the adjustment, light distribution shape determination unit 280F outputs light distribution shape information indicating the light distribution shape to light distribution command unit 290F.

[0119] After the light distribution pattern determination unit 280F in the control device 100F has performed the adjustment process, the illumination control unit 200F then ends the process shown in FIG.

[0120] According to this embodiment, it is possible to perform control that is more suited to the individual, based on the idea that the timing at which irradiation changes depends on the individual.

[0121] This embodiment further shows an example of the following configuration. a change condition receiving unit that outputs an operation image for receiving a change condition that is a condition for changing the irradiation range; a second change condition adjusting unit that adjusts a condition for changing the irradiation range based on the change condition received via the operation image; Furthermore, A control device characterized by: As a result, the present disclosure has an effect of providing a control device that allows the conditions for changing the illumination range to be adjusted according to personal preference.

The control system 1G shown in FIG. 19 includes a control device 100G, a lighting device 500, a DMS 600, an ECU 700, and an input / output device 800. The lighting device 500, the ECU 700, and the input / output device 800 are configured in substantially the same manner as the components of the same names that have already been described, and therefore a description thereof will be omitted. The control system 1G includes a control device 100G, a lighting device 500, a DMS 600, an ECU 700, and an input / output device 800. The lighting device 500 is configured in the same manner as the lighting device 500 already described. The DMS 600 is configured similarly to the DMS 600 already described. The ECU 700 is configured in the same manner as the ECU 700 already described. The input / output device 800 is configured in the same manner as the input / output device 800 already described.

[0124] The control device 100G uses the result of personal authentication to register change conditions for the irradiation range according to the preferences of each individual, and reads out the registered change conditions to use for adjusting the change conditions. The control device 100G includes a line-of-sight information acquisition unit 110G, an irradiation range acquisition unit 120G, a moving object information acquisition unit 130G, a biometric information acquisition unit 150G, a personal authentication unit 170G, and an irradiation control unit 200G. The line of sight information acquisition unit 110G, irradiation range acquisition unit 120G, moving body information acquisition unit 130G, and biometric information acquisition unit 150G are configured in almost the same manner as the components of the same names already described, and therefore their explanations are omitted.

[0125] The personal authentication unit 170G acquires personal authentication information that identifies each occupant of the vehicle on an individual basis. The personal authentication unit 170G acquires personal authentication information that is the result of the DMS 600 identifying the occupant of the moving body.

[0126] The illumination control unit 200G registers the authenticated occupant in association with the change condition set for the occupant. Furthermore, the illumination control unit 200G acquires the change conditions previously set by the personally authenticated occupant and adjusts the change conditions. The irradiation control unit 200G is configured to include a field of view range setting unit 210G (margin estimation unit 211, effective field of view angle setting unit 212), a light distribution change determination unit 220G, an output adjustment unit 230G, a first change condition adjustment unit 240G, a change condition reception unit 250G, a second change condition adjustment unit 260G, a setting management unit 270G, a light distribution shape determination unit 280G, and a light distribution command unit 290.

[0127] The setting management unit 270G stores the personal authentication information and the change condition received via the operation image in association with each other. The setting management unit 270G acquires the change condition corresponding to the personal authentication information acquired by the personal authentication unit 170G. That is, the setting management unit 270G stores the personal authentication information and the change condition received via the operation image in association with each other, and acquires the change condition corresponding to the personal authentication information acquired by the personal authentication unit 170G.

[0128] The second change condition adjustment unit 260G adjusts the conditions for changing the irradiation range using the change conditions corresponding to the personal authentication information acquired by the personal authentication unit 170G.

[0129] In addition to the functions of the light distribution pattern determination section 280 (280F) already described, the light distribution pattern determination section 280G determines the light distribution pattern based on the change conditions adjusted by the second change condition adjustment section 260G. Specifically, for example, light distribution pattern determination unit 280G outputs light distribution pattern information indicating the light distribution pattern according to the change timing or the irradiation range to be changed, which are the change conditions.

[0130] Next, a processing example of the control device according to the seventh embodiment of the present disclosure will be described. FIG. 20 is a flowchart showing an example of processing by the control device 100G according to the seventh embodiment of the present disclosure. The process shown in Fig. 20 is a control method performed by a control device. For example, by having a computer execute this control method using a program, the computer can function as a control device. When the control device 100G shown in Fig. 19 receives information from an external or internal control unit (not shown), it starts the processing shown in Fig. 20. Specifically, for example, when the control device 100G receives a change condition setting request from an external user operation, it starts the processing shown in Fig. 20.

[0131] Next, the control device 100G executes a personal authentication information acquisition process (step ST7100). In the personal authentication information acquisition process, the personal authentication unit 170G of the control device 100G acquires personal authentication information that identifies each occupant of the moving body on an individual basis. The personal authentication unit 170G acquires the personal authentication information output by the DMS600. The personal authentication unit 170G outputs the personal authentication information to the setting management unit 270G.

[0132] Control device 100G then executes a registration determination process (step ST7200 "Registered?"). In the registration determination process, the setting management unit 270G of the irradiation control unit 200G in the control device 100G refers to the setting management information stored in a memory unit (not shown) and determines whether or not the change condition information corresponding to the personal authentication information is registered by checking whether or not the change condition information is present.

[0133] If it is determined that the change condition has been registered (step ST7200 “Registered?” “YES”), setting management section 270G then executes a change condition acquisition process (step ST7300). In the change condition acquisition process, the setting management unit 270G of the irradiation control unit 200G in the control device 100G refers to the setting management information stored in a storage unit (not shown) and acquires the change condition information corresponding to the personal authentication information.

[0134] If setting management section 270G determines that the change condition has not been registered (step ST7200 “registered?” “NO”), it then executes a change condition registration process (step ST7400). In the change condition registration process, the setting management unit 270G of the irradiation control unit 200G in the control device 100G acquires the change conditions output by the second change condition adjustment unit 260G, and stores the change conditions in association with the personal authentication information and the change conditions received via the operation image. The setting management unit 270G stores the personal authentication information and second change condition information indicating the change condition received via the operation image in association with each other in a storage unit (not shown).

[0135] After executing the change condition acquisition process (step ST7300) or the change condition registration process (step ST7400), the control device 100G then executes a second change condition adjustment process (step ST7500). In the second change condition adjustment process, the second change condition adjustment unit 260G of the irradiation control unit 200G in the control device 100G uses the second change condition information to output adjustment information to the light distribution shape determination unit 280G that adjusts the change condition in the same manner as the second change condition adjustment unit 260F already described.

[0136] Control device 100G then executes adjustment processing (step ST7600). In the adjustment process, the light distribution pattern determination unit 280G of the illumination control unit 200G acquires the second change condition information output by the second change condition adjustment unit 260G. The light distribution pattern determination unit 280G performs adjustment based on the change conditions indicated in the second change condition information. The light distribution pattern determination unit 280G adjusts the change timing, which is the timing for changing the illumination range, or the size of the illumination range to be changed. After the adjustment, light distribution pattern determination unit 280G outputs light distribution pattern information indicating the light distribution pattern to light distribution command unit 290G.

[0137] After the light distribution pattern determination unit 280G in the control device 100G has performed the adjustment process, the illumination control unit 200G then ends the process shown in FIG.

[0138] According to this embodiment, it is possible to adjust the conditions for changing the irradiation range using the change conditions that have been registered once.

[0139] This embodiment further shows an example of the following configuration. a personal authentication unit that acquires personal authentication information that identifies each occupant of the vehicle; a setting management unit that stores personal authentication information and a change condition received via the operation image in association with each other, and acquires a change condition corresponding to the personal authentication information acquired by the personal authentication unit; Furthermore, The second change condition adjustment unit adjusting a condition for changing the irradiation range using a change condition corresponding to the personal authentication information acquired by the personal authentication unit; A control device characterized by: As a result, the present disclosure has the advantage that it is possible to read and use a change condition adjusted for each individual, thereby reducing the number of operations required by the user. Furthermore, the present disclosure achieves the same effects as those described above by applying the above configuration to a control system, the above control method, or the above program. Furthermore, the configuration of the present disclosure can be applied to all of the embodiments of the present invention, and provides the same effects as those described above.
