  Hereinafter, the present invention will be described based on embodiments.

  The vehicle door open notification illumination device 10 according to an embodiment of the present invention is provided at the left and right front doors of the automobile 1. However, in order to simplify the illustration and description, as shown in FIG. The vehicle door opening notification illumination device 10 attached to the outer opening door 2 on the right side in the traveling direction will be described as an example. In the figure, an open door (hereinafter, abbreviated as a door as appropriate) 2 is shown in an opened state. As shown in FIG. 2B, the vehicle door open notification illumination device 10 includes a light guide 11 that is a rod-shaped or belt-shaped light emitting portion, and an optical connection portion 12 that is connected to one end on the front side of the light guide 11. The LED unit 13 is a light emitting element optically coupled to the optical connecting portion 12.

  The light guide 11 is formed so as to efficiently guide the light emitted from the LED unit 13 from one end to the other end. In addition, the light guide 11 includes an other end portion 11 a that extends from the front side to the rear side on the inner surface of the door 2 on the vehicle interior side and is bent at a thickness portion 3 that is a rear side surface of the door 2. Yes. As shown in FIG. 2, the LED unit 13 includes red (RED), green (GREEN), and blue (BLUE) LEDs 13a, b, and c, and a Zener diode connected in parallel to the LEDs 13a, b, and c. 14a, b, c and resistors 15a, b, c connected in series to the LEDs 13a, b, c. The LED unit 13 configured as described above is formed so that the emission color, lighting, extinguishing, and blinking can be controlled by a sub ECU (electronic control unit) 16 that is a control unit. That is, the anode of each LED 13a, b, c is connected to the power source + B of the sub ECU 16. Lighting signals are supplied to the cathodes of the LEDs 13a, b, and c via the resistors 15a, b, and c, respectively. The sub ECU 16 includes an arithmetic processing unit such as a microcomputer, a power source, a memory, and the like. Further, the sub ECU 16 receives various information (for example, a trigger signal described later) from the upper main ECU 17.

  The trigger signal is a signal that triggers the LED unit 13 to light up. The trigger signal of the present embodiment includes a door opening detection signal output from a door opening / closing detection device (not shown) that detects that the outer opening door 2 has been opened, and a vehicle or pedestrian has approached behind the vehicle. A rear vehicle approach detection signal output from a rear sensing device (not shown) that senses this, and a door knob contact detection device (not shown) that detects that the passenger has touched the door knob of the outer door 2. A door knob contact detection signal and an ignition detection signal for detecting that the ignition key is in an ON state. Further, the sub ECU 16 turns on, blinks, and turns off the LED unit 13 in a preset light emission mode and controls the light emission color by a combination of trigger signals input from the main ECU 17.

  Next, a specific control example of the sub ECU 16 that controls the LED unit 13 will be described by dividing it into embodiments. Examples 1 to 3 are examples in which the LED unit 13 is controlled by a preset light emission mode based on the combination of trigger signals of the first embodiment provided with multi-color LEDs.

Example 1
The flowchart of the light emission mode control of Example 1 is shown to FIG. 3A. When the light emission mode control of the sub ECU 16 is started, it is determined whether or not the input ignition signal IG is on (S1). If it is on, it is determined whether or not the doorknob contact detection signal is on (S2). If the doorknob contact detection signal is off, the LED unit 13 is caused to emit light by a preset normal illumination (illumination: electrical decoration) (S3). The normal illumination is, for example, a mode in which the LED unit 13 emits light for the purpose of electrical decoration, and is a light emission mode that is different from alerting. When the doorknob contact detection signal is on, it is determined whether the approach detection signal for the rear vehicle etc. is on (S4). If the approach detection signal such as the rear vehicle is off, it is relatively safe, and the LED unit 13 is caused to emit light in the “blue” or “white” light alert mode (S5). Thereby, although a passenger needs to fully confirm the safety of the back, even if the door 2 is opened, it is safe.

  On the other hand, if the approach detection signal such as the rear vehicle is on, it is determined whether or not the door open detection signal is on (S6). If the door open detection signal is off, the LED unit 13 is caused to emit light in the “red” alert mode in order to call attention when the passenger opens the door (S7). At this time, if the door open detection signal is on, that is, if the occupant starts to open the door, the LED unit 13 blinks in “red” in order to alert the user sufficiently. Light is emitted (S8).

(Example 2)
As shown in the flowchart of FIG. 3B, the light emission mode control of the second embodiment is different from the first embodiment in that S4 and S6 of the first embodiment are replaced, and S6 is changed to S14 and S4 is changed to S16. Yes. Since the other steps are the same as those in the first embodiment, the same reference numerals are given and description thereof is omitted.

(Example 3)
The light emission mode control of the third embodiment is different from the flow chart of FIG. 3C in that step S2 in the flowchart of the second embodiment is omitted. Then, it is determined whether or not the door open detection signal is on (S14). If the door open detection signal is off, the LED unit 13 is caused to emit light by normal illumination (illumination: electrical decoration) (S3). To do. Since the other points are the same as those of the second embodiment, the same reference numerals are given and description thereof is omitted.

  As described above, in any example of the first embodiment, the passenger tries to open the door 2 using the detection signal of at least one of the door opening detection signal and the approach detection signal of the rear vehicle as a trigger signal. When or when it begins to open, the light guide 11 provided on the inner surface of the door 2 on the passenger compartment side emits light, so that the passenger's attention can be alerted. As a result, according to the first embodiment, when the passenger opens the door 2, it is possible to adjust the opening of the door 2 by remembering that a passenger or a pedestrian or the like must be careful. In addition, the safety of vehicles such as automobiles and pedestrians can be improved.

  Further, according to the first and second embodiments, when the detection signal that detects that the vehicle occupant has touched the door knob of the door 2 is input, the light guide 11 is set to “blue” in the third light emission mode or Since light is emitted in “white”, the light guide 11 emits light only when the passenger touches the door knob. As a result, the passenger notices that he / she must pay more attention to the vehicle or pedestrian behind, and the safety of vehicles such as automobiles and pedestrians can be improved.

  In the first embodiment, the example in which the light-emitting portion is formed by the rod-shaped or strip-shaped light guide body 11 having one end connected to the light-emitting element has been described. Light emitting elements such as LEDs can be arranged in a straight line. In any case, since the bar-shaped, belt-shaped or straight light-emitting portion provided on the inner surface of the door 2 on the passenger compartment side emits light, the alerting effect can be further improved.

  Further, in Examples 1 and 2 of the present embodiment, the light emission mode of the light guide 11 optically coupled to the LED unit 13 is changed depending on the color, blinking, blinking speed, and combinations thereof. It can be used properly according to the importance of. For example, the colors of the light-emitting portions can be divided, and “red” can be classified as “warning”, “blue or white” as “light alert”, and “red flashing” as “heavy alert”. Furthermore, if the blinking speed of “red blinking” is increased according to the approaching speed or distance of the rear vehicle, it is possible to urge the passenger to further “heavy attention”.

  Next, a specific light emission mode control example of the sub ECU 16 when the LED unit 13 of the first embodiment is changed to a single color (red) LED will be described in Examples 4 to 6. Examples 4 to 6 are examples in which the red LED is controlled by a light emission mode corresponding to a preset combination of trigger signals based on the same combination of trigger signals as in the first embodiment.

Example 4
As shown in the flowchart of FIG. 4A, the fourth embodiment is different from the first embodiment in that the light emission mode of the first embodiment is differently used for “red” and “red blinking”. The description is omitted because it is the same.

(Example 5)
As shown in the flowchart of FIG. 4B, the fifth embodiment is different from the second embodiment in that the light emission mode of the second embodiment is selectively used as “red” and “red blinking”. The description is omitted because it is the same.

(Example 6)
As shown in the flowchart of FIG. 4C, the sixth embodiment is different from the third embodiment in that the red light mode and the “flashing red” are used separately. Also, unlike the other examples 1 to 5, the light is emitted in the normal illumination mode even when the IG detection signal is off. Since the other points are the same as those of the third embodiment, description thereof is omitted.

  As mentioned above, although this invention was demonstrated based on one Embodiment and an Example, this invention is not limited to these, It is possible to implement in the form changed or changed in the range of the main point of this invention. Certainly, it will be obvious to those skilled in the art, and such variations or modifications are naturally within the scope of the claims of this application. For example, in conjunction with the seat belt, only the light guide 11 of the outer opening door 2 on the side on which the passenger is on can be caused to emit light.
