The above-described LED wiring board 73, display body 75, and the like are accommodated in the covering glass 12.

  Next, the operation of the display device 1 configured as described above will be described below with reference to FIG. First, the CPU 9 starts the operation in response to power-on from the battery, controls the LED driver IC 72, turns off all the LED rows 71, and stops the display on the display unit 7 (step S1). Next, the CPU 9 detects the state of the ignition switch, and if the ignition switch is on (Y in step S2), the CPU 9 determines that the vehicle 2 is traveling and controls the motor driver IC 87, As shown in FIG. 6 (A), the LED wiring board 73 is rotated in the direction of the arrow Y1 so that the LED wiring board 73 is directed to the outside visual recognition position (step S3).

  Next, based on the input from the position detection I / O 88, the CPU 9 detects whether or not the intermediate gear 85 has come into contact with a stopper (not shown) and the LED wiring board 73 has reached the visually recognized position outside the vehicle (step S4). . If it has not reached the vehicle outside view position (N in step S4), the CPU 9 returns to step S3 again and continues the rotation of the LED wiring board 73 in the arrow Y1 direction.

  On the other hand, when it is detected that the vehicle outside visual recognition position has been reached (Y in step S4), the CPU 9 now controls the motor driver IC 87 to move the LED wiring board 73 by the arrow Y2 (FIG. 6B). )) After rotating in the direction, the drive of the motor 83 is stopped (step S5). Thereby, as shown in FIG. 6 (B), the LED wiring board 73 becomes the in-vehicle visual position where it is directed to the combiner 6. At the in-vehicle viewing position, the virtual image of the display unit 7 reflected by the combiner 6 is viewed from the driver's seat, and the display unit 7 can be easily viewed from the inside of the vehicle.

  Next, the CPU 9 acquires an economy degree value from various sensors provided in the vehicle 2 (step S6). This economy degree value is a value indicating the fuel consumption state of the vehicle 2, and may simply be the fuel consumption itself, or may be an achievement rate with respect to the target fuel consumption. In addition, in the vehicle 2 in which the economy mode in which the engine speed is reduced than in the normal mode can be set, the ratio between the operation time in the economy mode and the operation time in the normal mode may be used.

  The CPU 9 converts the acquired economy degree value into the display state of the LED array 71 (step S7). In the present embodiment, the green LED 71G and the orange LED 71O are caused to emit light, and the economy degree value is displayed. That is, the center of the LED row 71 arranged in the Y direction emits light in green, and both ends emit light in orange. In the boundary region between green and orange, the emission luminance of the green LED 71G is decreased as it approaches the both ends, and the emission luminance of the orange LED 71O is decreased toward the center. Thereby, a gradation can be added to the boundary region between the central green and the orange at both ends.

  Then, if the economy degree value is good, the CPU 9 converts the display state so that the central green light emitting area is lengthened and the orange light emitting areas at both ends are shortened accordingly. On the contrary, if the economy degree value is bad, the display is converted to a display state in which the central green light emitting region is shortened and the orange light emitting regions at both ends are lengthened accordingly. Thereafter, the CPU 9 controls the LED driver IC 72 to turn on the LED row 71 so as to obtain the display state converted in step S6 (step S8), and then returns to step S2. Thus, the economy degree value is displayed on the display unit 7 while the vehicle is traveling.

  On the other hand, the CPU 9 detects the state of the ignition switch. If the ignition switch is off (N in step S2), the CPU 9 determines that the vehicle 2 is stopped, and then a portable terminal such as an intelligent key. It is determined whether or not an outside vehicle confirmation signal is received in response to the operation (step S9). If the vehicle outside confirmation signal is not received (N in Step S9), the CPU 9 determines that there is no driver near the outside of the vehicle, returns to Step S1, and stops the display on the display unit 7.

  On the other hand, when the vehicle outside confirmation signal is received (Y in step S9), the CPU 9 determines that the driver is near the outside of the vehicle and controls the motor driver IC 87, as shown in FIG. Then, the LED wiring board 73 is rotated in the direction of the arrow Y1 so that the LED wiring board 73 is directed to the outside visual recognition position (step S10).

  Next, based on the input from the position detection I / O 88, the CPU 9 detects whether or not the intermediate gear 85 is in contact with a stopper (not shown) so that the LED wiring board 73 reaches the vehicle outside visual recognition position (step S11). . If the outside visual recognition position has not been reached (N in Step S11), the CPU 9 returns to Step S10 again and continues the rotation of the LED wiring board 73 in the arrow Y1 direction.

  On the other hand, when it is detected that the vehicle outside view position has been reached (Y in step S11), the CPU 9 immediately controls the motor driver IC 87 to stop driving the motor 83 (step S12). Thereby, as shown to FIG. 6 (A), it becomes the visual recognition position outside a vehicle in which the LED wiring board 73 is orient | assigned to the vertical direction upper side. At the outside visual recognition position, the display unit 7 can be easily seen even through the windshield 5 outside the vehicle. Next, the CPU 9 acquires a battery capacity value from various sensors provided in the vehicle 2 (step S13). This battery capacity value is a value indicating the state of charge of the battery (battery) and the remaining amount.

  The CPU 9 converts the acquired battery capacity value into the display state of the LED array 71 (step S14). In the present embodiment, the white LED 71W is caused to emit light and the battery capacity value is displayed. That is, the center of the LED row 71 arranged in the Y direction is caused to emit white light and both ends are turned off. In the boundary region between white and light extinction, the light emission luminance of the white LED 71W is reduced as it approaches both ends. Thereby, gradation can be given to both ends of the white light emitting region.

  If the battery capacity value is large, the CPU 9 converts the display state such that the central white light emitting area is lengthened, and conversely if the battery capacity value is small, the central white light emitting area is shortened. Thereafter, the CPU 9 controls the LED driver IC 72 so that the display state converted in step S14 is turned on to turn on the LED row 71 (step S15), and then returns to step S2. Thereby, when the vehicle is stopped and a signal from the portable terminal is input, the battery capacity value is displayed on the display unit 7.

  According to the display device 1 described above, by disposing the display device body 4 on the upper surface of the dashboard 3, the display device 1 can be easily seen from both inside and outside the vehicle. In addition, the CPU 9 displays the economy degree value and the battery capacity value on the display unit 7 both when the vehicle 2 is traveling and when a signal from a portable terminal such as an intelligent key is input while the vehicle 2 is stopped. Therefore, if a signal from a portable terminal such as an intelligent key is input outside the vehicle while the vehicle is stopped, the battery capacity value can be visually recognized from outside the vehicle by using the display unit 7 that displays the economy degree value during traveling.

  Further, according to the display device 1 described above, the CPU 9 switches display contents between when the vehicle is traveling and when a signal from the portable terminal is input while the vehicle is stopped, so that the person outside the vehicle can Can display vehicle information (battery capacity value in the present embodiment) necessary outside the vehicle, and can display vehicle information (economy degree value in the present embodiment) necessary in the vehicle for those who are in the vehicle.

  Moreover, according to the display apparatus 1 mentioned above, the display part 7 is arrange | positioned on the dashboard 3 of a plug-in hybrid vehicle, a hybrid vehicle, or an electric vehicle, and CPU9 is in the fuel consumption state of the vehicle 2 during driving | running | working of the vehicle 2. A certain economy degree value is displayed on the display unit 7, and when a signal from a portable terminal such as an intelligent key is input while the vehicle 2 is stopped, the state of charge or the remaining battery level of the battery (battery) provided in the vehicle 2 The battery capacity value is displayed. Thereby, since the battery capacity value can be grasped while being outside the vehicle, the battery can be charged smoothly.

  Further, according to the display device 1 described above, the moving mechanism 8 moves the display unit 7 to the in-vehicle viewing position while the vehicle 2 is traveling, and even moves the display unit 7 to the outside viewing position while the vehicle 2 is stopped. Further, it becomes easier to see from both inside and outside the vehicle.

  Further, according to the display device 1 described above, the display unit 7 includes the LED array 71, the LED wiring board 73 on which the LED array 71 is mounted, and the cylindrical display body 75 that houses the LED wiring board 73.

As a result, the LED wiring board 73 can be easily moved between the in-vehicle viewing position and the in-vehicle viewing position simply by rotating.

  In the above-described embodiment, when the vehicle 2 is traveling and when a signal from a portable terminal such as an intelligent key is input while the vehicle 2 is stopped, the display content of the display unit 7 is changed to the economy degree value and the battery. Although switching between capacitance values has been performed, the present invention is not limited to this. The display contents do not need to be switched, and the same vehicle information (for example, battery capacity value) is displayed both when the vehicle 2 is traveling and when a signal from the portable terminal is input while the vehicle 2 is stopped. May be.

  In the above-described embodiment, the economy degree value and the battery capacity value are displayed as the vehicle information, but the present invention is not limited to this. Other vehicle information may be displayed.
