A control unit 6 includes a solar radiation sensor 10 that detects the amount of solar radiation from the outside of the vehicle, an outside air temperature sensor 11 that detects the temperature outside the vehicle, an indoor temperature sensor 12 that detects the temperature inside the vehicle, and an indoor illuminance sensor 13 that detects the brightness inside the vehicle. , An indoor temperature sensor 14 that detects an indoor temperature, a seating sensor 15 that detects a seating position of an occupant, a vehicle speed sensor 16, etc.
Lighting of a plurality of self-luminous elements, color control, and the like are performed. Further, an operation unit 8 including a power source 5, a power switch 7 and a manually operated switch is connected to the control unit 6.

The self-luminous element 20 is composed of a light-emitting element plate such as a liquid crystal panel or a panel-shaped electroluminescence element plate 1, a skin 2, an AC power supply controller 3, and a connection terminal 4.

An electroluminescence element plate, which is an example of a light emitting element plate, has a structure in which both sides of a plate-shaped resin derivative mixed with a phosphor are sandwiched between thin parallel plates, and an AC power controller 3
The color can be changed by controlling.

The epidermis 2 has a large number of small slits in a lattice pattern, and the lattice points are flocked.

The outer skin 2 has an interior color selected by the user in advance.

FIG. 2 shows an example in which the self-luminous element 20 is incorporated into an interior structure, and includes an upper surface 21, a front surface 22 (a side closer to an occupant), a front surface 23, and a pillar portion 24 of the instrument panel 17.
It is incorporated in the part.

Note that the self-luminous element 20 at each location may be a divided one instead of one and may be covered with a skin.

Next, the operation will be described with reference to the operation flow chart of FIG.

When the power is turned on 25, manual / automatic mode selection 26 is performed. The automatic mode is selected unless the manual mode is selected.

In the case of manual selection, the manual control 27 of each part by operating the operation part 8 or the like is prioritized, and the control part 6 performs calculation etc., and operates (lighting on / off of the self-luminous element 20, adjustment of chromaticity, etc.). ) The control instruction 28 is output from the control unit 6.

Receiving this output, the operation of each of the self-luminous elements 20a, 20b, 20c is controlled.

If there is an instruction to stop the operation (operation OFFsw signal) 29, the operation is stopped by the power OFF 31 according to the determination 30 to continue the operation. If there is no instruction, the operation continues.

On the other hand, in the case of automatic selection, data reading 32 of various sensors such as a solar radiation sensor 10, an outside air temperature sensor 11, an indoor air temperature sensor 12, an indoor illuminance sensor 13, an indoor temperature sensor 14, a seating sensor 15, a vehicle speed sensor 16 is performed. .

The control unit 6 performs the lighting pattern calculation 34 based on the read data and the selection pattern based on the signals 33 from the selection 33 of the desired mode patterns a, b and c and the data from the various sensors.

As a result, the control pattern judgment 35 for each part is performed, and the operation (lighting,
The control unit 8 outputs an instruction 36 for turning off and adjusting the chromaticity.

Here, the mode patterns a, b and c are, for example, in the example in which the self-luminous element 20 of FIG. 2 is incorporated in the internal structure, the mode pattern a is the instrument panel upper surface 21, the front surface 22,
23, all the self-luminous elements 20 incorporated in the pillar 24 are instructed to operate. The mode pattern b instructs the self-luminous element 20 incorporated in the instrument panel upper surface 21 and the pillar 24 to operate. The mode pattern c instructs the operation of only the self-luminous element 20 incorporated in the pillar 24.

According to the instruction 36, the self-luminous elements 20a, 20b ... 20c are activated (lighted, extinguished, adjustment of chromaticity etc.).

If there is an operation stop signal (operation OFFsw signal) 37, the power supply is turned OFF 39 by the operation continuation judgment 38, and the operation is stopped.

Next, a specific operation example of the self-luminous element 20 will be described.

(Example 1) When the light of sunlight entering through the windshield is strong in relation to the interior color selected by the user in advance, the windshield is reflected and visibility is reduced. However, according to the present invention, the self-luminous element (see FIG. 2) on the upper surface 21 of the instrument panel responds to the signal from the solar radiation sensor 10 for detecting the intensity of direct sunlight, and is closer to black as the intensity of solar radiation is stronger. It emits light to prevent reflections.

Further, since the skin 2 of the self-luminous element 20 has a large number of slits in a grid pattern, light is diffusely reflected, and the grid points are flocked, so that the occupant does not feel dazzling.

(Example 2) Depending on the room temperature, if the interior color of the passenger compartment is cold (for example, 15 ° C or lower), a warm color (red)
If it is hot (for example, 25 ° C or higher), it is cold (blue)
The emission color of the self-luminous element 20 is changed to the color of. Further, it is possible to change the set temperature to be changed according to the season.

(Example 3) A seat sensor 15, such as a tape switch provided at the seating position, detects whether or not the passenger is sitting in the passenger seat or rear seat in addition to the driver seat, and incorporates it into the interior structure. The position at which the self-luminous element 20 is illuminated is changed.

It is also possible to change the luminescent chromaticity to suit the occupant's taste.

(Example 4) The lighting pattern of the self-luminous element is changed between low speed and high speed by a signal from the vehicle speed sensor 16. Also, at high speeds, it is possible to emit a reddish color in order to call attention to the driver.

(Example 5) A wakeful state of a nighttime driver is detected, and the light emission color of a self-luminous element is changed according to the degree to change the driver's mood and prevent a dozing driver.

An example of the application has been described above, but the range of application is extremely wide.

Since the self-luminous element is separately installed in each interior portion, if the element is damaged, only that portion may be replaced.

Further, in the above-mentioned embodiment, the case where the color of the surface of the interior material is changed has been described, but it is also possible to emit an appropriate scent according to the color to stimulate the occupant's awakening and further improve the mood.

(Effect) As described above, the present invention detects a plurality of interior materials having discolorable emitting elements and a vehicle environment in an automobile interior structure in which discolorable emitting elements are provided on the surface of the interior material. Since various sensors and a control unit that adjusts the color, brightness, etc. of the light emitting element according to signals from the various sensors are provided, the light emitting color and the light emitting brightness of the light emitting element are changed according to the environment of the vehicle. It is possible to control it, improve the aesthetics of the interior, and prevent it from being reflected on the windshield when it is exposed to direct sunlight.

The color of the interior can be changed according to the room temperature and the seating position of the passengers, which further improves the riding comfort.

Safety can be improved because the interior color can be changed to a color that alerts the driver depending on the traveling vehicle speed such as low or high speed or the driver's awake state.

And so on, an extremely excellent effect can be obtained.
