The roof trim 14 also has the same configuration as the seat backs 16a and 17a, and uses the vehicle lighting structure. In the roof trim 14, the LED strip lights 40 are arranged side by side in the vehicle width direction while extending in the vehicle front-rear direction. It is intended to diffuse light in the longitudinal direction, particularly toward the front of the vehicle.

Also, the LED tape lights 40 arranged on the door trim 12 , roof trim 14 and seat backs 16 a and 17 a are controlled by a control device (control section) 70 mounted on the vehicle 10 . The control device 70 is mainly composed of a computer including a CPU, ROM, and RAM, and is connected to the LED strip light 40 by a cable. The control device 70 can control each LED 44 independently. Control in this vehicle lighting structure will be described in detail below with reference to a block diagram showing the functional configuration of the control device 70 in FIG. 6 and a flowchart of an LED control program executed by the control device 70 in FIG.

An overhead module (not shown) is provided on the ceiling of the vehicle 10, and the module has an in-vehicle camera 80 capable of imaging an occupant seated in the rear seat (for example, an occupant H seated on the right side of the rear seat). is provided. The control device 70 is also connected to an in-vehicle camera 80 and can acquire data captured by the in-vehicle camera 80 . The control device 70 has a motion sickness determination unit 82 for determining whether or not there is a risk of motion sickness and whether or not the occupant has signs of motion sickness. abbreviated as "S1". The same applies to other steps.), the expression, posture, etc. of the occupant H are recognized based on the captured image data of the in-vehicle camera 80, and whether the occupant H is likely to get motion sickness. or whether there is a sign of motion sickness. Then, when the motion sickness determination unit 82 determines that the occupant H is likely to have motion sickness or that there is a sign of motion sickness, the control device 70 executes S2 and subsequent steps so that the occupant H In order to suppress motion sickness, or to recover from motion sickness, lighting of the LED tape light 40 arranged in the above-described interior material is controlled.

More specifically, the control device 70 sequentially changes the LED tape lights 40 arranged on the door trim 12 and the roof trim 14 from the ones on the front side of the vehicle to the ones on the rear side of the vehicle. As a result, on the door trim 12 and the roof trim 14, an image is expressed in which the light flows toward the rear of the vehicle, as shown in FIG. 8(a). In addition, for the LED tape lights 40 arranged on the seat backs 16a and 17a, the ones that are lit among the plurality of LEDs 44 are sequentially changed from the upper side to the lower side so that the seat backs 16a and 17a are illuminated. In the upper part, an image in which light flows downward is represented as shown in FIG. 8(b). The flowing light is changed based on the data acquired by the vehicle information acquiring section 76 described above. For example, the control device 70 changes the speed at which light flows and the length of light (change in the number of LEDs 44 that are lit at the same time) according to the acceleration or deceleration of the vehicle. This flowing light can give the occupant a visual-induced self-motion sensation (vection effect), which is a feeling that the occupant is moving according to visual information, and can reduce motion sickness of the occupant.

It is believed that the vectoring effect described above is more effective when projected in the peripheral visual field R2 (peripheral visual field) than when projected in the occupant's central visual field R1 (central visual field). Taking advantage of this, in this embodiment, the LEDs 44 located in the central vision region R1 are not turned on, and only the LEDs 44 located outside the central vision region R1 are used to express the flowing light. It's becoming For example, as shown in FIGS. 1 and 2, consider a case where the line of sight E of the passenger H is directed toward the headrest 16b of the driver's seat 16. FIG. In this embodiment, the occupant's central visual field (the area inside the dashed-dotted line L1 in FIGS. 1 and 2) is centered on the line of sight E, and the central visual field angle in the vertical direction is defined as _θA . 1 and 2, the approximate outer boundary of the occupant H's peripheral vision area is indicated by a two-dot chain line L2, and the peripheral vision area R2 is inside L2 and excludes the central vision area. area. In other words, when the line of sight E of the occupant H is as shown in FIGS. 1 and 2, some of the LEDs 44 arranged on the door trim 12 and the roof trim 14 positioned within the central vision region R1 are not turned on. It has become.

The control device 70 defines a line-of-sight detection processing unit 84 that performs processing for detecting the line-of-sight E of the occupant H based on the acquired image data of the in-vehicle camera 80, and defines a central visual region R1 of the occupant H based on the line-of-sight E. and a central vision region defining portion 86 that defines the central vision region. In this embodiment, it can be considered that the line-of-sight detection unit 88 includes the in-vehicle camera 80 and the line-of-sight detection processing unit 84 . When the motion sickness determination unit 82 detects signs of motion sickness in the occupant H, the control device 70 detects the line of sight E of the occupant H by the line of sight detection processing unit 84 in S3, and detects the line of sight E of the occupant H in S4. The region defining unit 86 defines the central vision region R1 with the line of sight E as a reference. Then, in S5, only the LEDs 44 positioned outside the central vision region R1 are determined to be lit among the plurality of LEDs 44 .

Next, in S6, the LED control unit 90 provided in the control device 70 acquires information about the vehicle 10 by the vehicle information acquisition unit 76, and in S7, based on the acquired vehicle information, determines the speed and length of light flow. decide. Then, in S8, a control signal is transmitted to each LED tape light 40, so that only the LEDs 44 positioned outside the central vision region R1 are used to express the image of flowing light as shown in FIG. of.
