Conventionally, lighting equipment at the rear of an automobile includes left and right direction indicator lights, back indicator lights, brake indicator lights, tail lights, number lights, etc., and each lighting equipment is provided with its own lamp.

Therefore, a large number of lamps are required, and in order to detect a disconnection failure in each lamp, each lamp must be equipped with a disconnection detection device, and a backup device that switches on and lights up in the event of a disconnection failure of the lamp must be installed. Providing lamps is difficult to implement because the number of lamps becomes very large. The present invention solves the above problem by driving a common light emitting means with commands corresponding to various types of illumination, and selectively switching and introducing illumination light from the light emitting means to the illumination surface corresponding to the command. By doing so, the light emitting means can be shared by multiple lighting devices, and therefore failure detection of the light emitting means and switching to the preliminary light emitting means in response to the failure can be performed with a simple configuration. The object of the present invention is to provide a lighting equipment integrated control device that can control lighting equipment.

Next, the operation of the above configuration will be explained with reference to the flowchart shown in FIG.

FIG. 2 shows arithmetic processing performed by the on-vehicle computer 7 according to a predetermined program. First, when the left turn switch 2, right turn switch 3, back switch 4, brake switch 5, and night light switch 6 are all open, there is no output from the 0R logic 100 in FIG. The calculation process does not start, the main lamp 8 and the auxiliary lamp 9 remain off, the screen control device 10 also does not operate, and the left lighting section 12, number plate lighting surface 13, and right lighting section 14
None of these are in the lighting state.

Further, the disconnection warning device 15 also remains inactive. Next, when the driver closes the left turn switch 2 when turning left during daytime driving, the in-vehicle computer 7 receives this command and generates an interrupt command of the logic output of the 0R logic 100 in FIG. Proceeding to step 101, calculation processing for various types of illumination is started.

Thereby, the process proceeds to left turn switch determination step 102 for determining whether or not the left turn switch 2 is closed.
The determination result is YES, and the process proceeds to step 103 of the lamp first energization process. In this processing step 103, the main lamp 8 is turned on and its illumination light is controlled to have an intensity corresponding to the direction instruction. Subsequently, the process proceeds to first screen opening/closing processing step 104, where a screen control signal for instructing a left turn is applied to the screen control device 10, the first screen 10a is periodically opened and closed, and the optical fiber 1
1 through the left-hand side illumination section 12.
The flashing lights of a are started and a left turn indication is started for following vehicles. Next, the process proceeds to a right turn switch judgment step 107 in which it is judged whether or not the right turn switch 3 is closed, and if the judgment is NO, the second energization is canceled and the second screen is removed without going through processing steps 108 and 109. After passing through the release processing steps 110 and 111, the process proceeds to the next back switch determination step 112 for determining whether or not the back switch 4 is closed.

At this time, in the second energization and second screen release processing steps 110 and 111, since the second energization and the second screen are not activated, only the non-activated state is maintained and no special operation is performed. Then, the determination in the back switch determination step 112 also becomes NO, and the process proceeds to the processing step 11.
Brake switch determination step 117 for determining whether or not the next brake switch 5 is closed through the third energization release and third screen release processing steps 115 and 116 without going through steps 3 and 114. Proceed to. At this time as well, in the third energization and third screen release processing steps 115 and 116, no special operation is performed and the non-operating state is maintained as in the above case. Then, the judgment in the brake switch judgment step 117 is also NO, and the next night switch 6 is closed without passing through the processing steps 118 and 119, and passing through the processing steps 120 and 121 for canceling the fourth energization and canceling the third screen. The process proceeds to a night switch determination step 122 for determining whether or not the switch has been activated. At this time as well, the fourth energization and fourth screen release processing step 12
At 0,121, no special operation is performed and the non-operating state is maintained as in the above case. Then, the judgment in the night switch judgment step 122 is also NO, and the process steps 123,
The process proceeds to the lamp disconnection determination step 127 for determining whether the next lamp has a disconnection failure or not through the fifth energization release and fifth screen release processing steps 125 and 126 without going through step 124. At this time as well, in the fifth energization and fifth screen release processing steps 125 and 126, no special operation is performed and the non-operating state is maintained as in the above case. When the process proceeds to the lamp breakage determination step 127, if no lamp breakage failure has occurred, the process proceeds to an end step 128, and then, in another system calculation processing step 129, other systems other than the above-mentioned lighting control are determined. After performing the arithmetic processing, the process returns to start step 101 and the same arithmetic processing is repeated again.

The calculation processing time for this one cycle is approximately several tens of Msec. After that, when the driver depresses the brake pedal to decelerate to make a left turn, the brake switch 5 closes and a command signal for brake display is sent to the on-board computer 7. join.

As a result, when the calculation process in FIG. 2 advances to brake switch determination step 117, the determination changes from NO to Y.
The process is reversed to ES and proceeds to step 118 of the fourth lamp energization process. In this processing step 118, the current flowing through the main lamp 8 is adjusted to make the intensity of the illumination light correspond to the left turn indication and the brake indication, and then the process proceeds to the fourth screen opening processing step 119, where the screen for the brake indication is In addition to the control device 10, the fourth screen 10d is opened and illumination of the brake instruction illumination surfaces 12c and 14c of the left side illumination unit 12 and right side illumination unit 14 is started through the optical fiber 11, thereby adding a brake indication to the following vehicle. do. This delay in brake display is at most one cycle of the arithmetic processing routine, but since the time is approximately several + Msec, there is no problem. When the driver releases the brake pedal while proceeding with the left turn, the brake switch 5 is released, so when the on-board computer 7 proceeds to the brake switch determination step 117 in the calculation processing routine shown in FIG. The judgment is YES to NO
Then, the process proceeds to the fourth energization release processing step 120.

In this process step 120, the fourth current supply to the main lamp 8 is stopped, and in the fourth screen release process step 121, the fourth screen 10d is closed and the brake display is canceled. At this time, since the left turn switch 2 remains closed, the blinking illumination of the left turn indication illumination surface 12a continues. When this left turn is completed and left turn switch 2 is released,
Immediately after that, when the arithmetic processing of the onboard computer 7 proceeds to left turn switch determination step 102, the determination is reversed from YES to NO, and the first energization release processing step 1 is started.
At 05, the first energization to the main lamp 8 is canceled, and then the first
In screen release processing step 106, the first screen 10a in the screen control device 10 is closed, and the flashing illumination by the optical fiber 11 and the left turn indication illumination surface 12a is stopped.

After this process is followed by right turn switch determination step 107, the same calculation process as described above is performed. As a result, each illumination is turned off and the main lamp 8 is turned off. Next, when the right turn switch 3 is closed for a right turn, the command is applied to the on-vehicle computer 7, so that the arithmetic processing shown in FIG. 2 is started in the same manner as in the case of the left turn described above.

Then, only the determination in the right turn switch determination step 107 becomes YES, and in the second lamp energization processing step 108, the main lamp 8 is turned on, and the second energization is controlled so that the intensity of the illumination light corresponds to the right turn flashing illumination. Then, in a second screen opening/closing processing step 109, the second screen 10b in the screen control device 10 is opened and closed periodically, and the blinking illumination of the right turn indication illumination surface 14a in the right side illumination section 14 is started through the optical fiber 11, and the subsequent Starts a right turn indication to cars. Other various judgment steps 10
The determinations of 2, 112, 117, and 122 are all NO, and the corresponding lighting operation does not occur. When the brake pedal is depressed while proceeding with a right turn, a brake display is performed in the same manner as in the case of the left turn described above. When the brake operation is released, the brake display disappears, and when the right turn switch 3 is released when the right turn is completed, the right turn blinking light also disappears.
Next, when the gear change lever is put into the reverse position when reversing, the back switch 4 is closed in conjunction with this, and the command is applied to the on-vehicle computer 7.

As a result, the arithmetic processing shown in FIG. 2 is started, and only the determination at the back switch determination step 112 becomes YES.
In the third lamp energization process step 113, the main lamp 8 is turned on and the third energization is controlled to make the intensity of the illumination light correspond to the back display.Furthermore, in the third screen opening process step 114, the screen is controlled. Equipment 1
The third screen 10c at 0 is opened, and the back display by illuminating the back indication illumination surfaces 12b, 14b of the left side illumination section 12 and right side illumination section 14 through the optical fiber 11 is started. After this back display starts, the car moves backwards, and then the brake pedal is depressed to stop the backward movement, and the brake switch 5 is closed, and the judgment at the brake switch judgment step 117 is reversed from NO to YES. , lamp fourth energization processing step 118 and fourth lamp energization processing step 118
In the screen opening processing step 119, a brake display is added by illuminating the left and right brake indicating illumination surfaces 12c and 14c in the same manner as described above. As a result, when the car stops and the brake pedal is released, the brake switch 5 is released, and the brake switch determination step 117 is performed.
The determination returns from YES to NO, and . 7. The brake display is canceled by the fourth energization cancellation processing step 120 and the fourth screen cancellation processing step 121. After that, when the gear shift lever is removed from the reverse position, the back switch 4 is opened, and the determination immediately after that at the back switch processing step 112 is reversed from YES to NO, and the third energization release processing step 115 and the third screen release processing step 116 are performed. While turning off the main lamp 8, the third screen 10
c, and turn off the illumination of the back instruction illumination surfaces 12b and 14b to cancel the back display (4). Next, when the night switch 6 is closed for night driving, the command is sent to the on-vehicle computer 7.

As a result, the arithmetic processing shown in FIG. 2 is started, and only the judgment in the night switch judgment step 122 becomes YES, and in the fifth lamp energization processing step 123, the main lamp 8 is turned on and the intensity of its illumination light is adjusted. The fifth energization is controlled to correspond to the vehicle width display and the number plate illumination, and further, in a fifth screen opening processing step 124, the fifth screen 10e in the screen control device 10 is opened, and the left side illumination section is passed through the optical fiber 11. The vehicle width indicating illumination surfaces 12d and 14d of the vehicle width indication illumination surfaces 12d and 14d of the right side illumination section 12 and the right side illumination section 14 are started to be illuminated, and the number plate illumination surface 13 is also brought into the illumination state to illuminate the number plate. During night driving, corresponding displays are added when turning left, turning right, applying the brakes, and reversing in the same way as the above-mentioned operations during daytime driving.

Next, when the main lamp 8 becomes in a disconnection failure state during each of the above lighting operations, the determination in the lamp disconnection determination step 127 in the calculation process shown in FIG. 2 is reversed from NO to YES, and the process proceeds to disconnection warning processing step 130.

In this processing step 130, a disconnection warning signal is applied to the disconnection warning device 15 to issue a disconnection failure warning. Next, the process advances to a spare lamp switching process step 131, where the spare lamp 9 is switched on, and the process returns to the left turn switch determination step 102 immediately after the start step 101. Thereby, each illumination can be continued by the backup lamps 9 even when the main lamp 8 has a disconnection failure. In this state, each lighting operation is performed in the same manner as described above. In addition, although the above-mentioned embodiment shows the integrated control of the lighting of various lighting devices at the rear of the car, if the lighting of two or more lighting devices is to be integrated, the integrated control of other lighting devices of the car is possible. Alternatively, integrated control of various lighting devices other than automobiles may be performed.

As described above, in the present invention, a common light emitting means is driven by commands corresponding to various types of illumination from a command means that issues various illumination commands, and the illumination light from the light emitting means is switched to the above by the switching means. Since the control means is used to selectively switch and introduce each lighting surface corresponding to each command, each lighting control can be performed simply by providing the light emitting means that is common to multiple lighting devices. can be integrated,
Therefore, it is possible to easily detect a failure in the light emitting means, and it is also possible to easily switch to the backup light emitting means in the event of a failure, which is an excellent effect.
