Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
First, the first embodiment will be described.
As shown in FIG. 2, the vehicle notification control system 100 according to the present embodiment is provided in a vehicle body 10 of a truck including a cab body 12 and a wing body 14 for cargo handling, for example. In addition, the wing body 14 is provided with wing side panels 14a and 14d, side surface front tilts 14b and 14e, side surface rear tilts 14c and 14f, and rear doors 14g and 14g so as to be openable and closable.

Further, as shown in FIG. 1, the vehicle notification control system 100 includes a control unit 110, a memory 120, an operation detection unit 130, and a light emitting unit 140, which are connected to each other via a signal line 150. Then, the vehicle notification control system 100 first blinks twice at a predetermined time interval during the backward movement operation of the vehicle body 10 and then blinks three times, and during the backward movement operation, blinks twice in a predetermined pattern, that is, twice. It has a function of controlling the light emitting unit 140 so that the blinking operation is continued in the order of blinking once, and after the backward movement operation is finished, the blinking operation is terminated and turned off. On the other hand, the vehicle notification control system 100 first blinks twice at a predetermined time interval during an operation different from the backward operation of the vehicle body 10, and then blinks twice during the different operation, which is a different pattern from the backward operation. It has a function of continuing the operation and, after the operation is completed, controlling the light emitter unit 140 so as to end the operation of blinking twice and turn off the light.

The control unit 110 has a function of controlling the entire system by referring to predetermined program information stored in the memory 120. Further, the control unit 110 has a function of referring to the memory 120 for blinking operation information that matches the detected operation information based on the detected operation information from the operation detection unit 130, and controlling the blinking operation of the light emitting unit 140.

The memory 120 is a readable / writable storage device. The memory 120 controls a program information area 120a for storing program information referred to by the control unit 110 for various control processing / management, a work area 120b for performing various works, and various blinking operations of the light emitter unit 140. It has a storage area such as a blinking operation information area 120c for storing information for performing.

Here, the blinking operation information stored in the blinking operation information area 120c is blinking control information for performing a blinking operation according to an operation on the vehicle body 10 referred to by the control unit 110. That is, the blinking control information is hazard blinking control information, backward blinking control information, and, for example, wing / flapping open / close blinking control information which is an operation different from that during backward movement. The control information corresponding to the operation different from the backward movement is not limited to the blink control information at the time of opening / closing the wing / tilt, but other control information such as blink control information at the time of opening / closing the door or PTO (Power Take-Off) operation It goes without saying that it may be blinking control information or the like.

Now, the hazard blinking control information is information to be referred to by the control unit 110 when it is determined that the operation instruction for blinking the hazard lamp has been issued, and the blinking of the light emitting unit 140 is performed at a constant time interval until the operation instruction is canceled. This is information for continuing the operation.

The backward blinking control information is information to be referred to when the control unit 110 determines that the backward operation instruction has been given, and is information for continuing the blinking operation of the light emitting unit 140 until the backward operation instruction is released. Is. That is, when the retreat operation is performed, the light emitter section 140 is first blinked m times (m is a natural number), for example, twice at a predetermined time interval, and then during the retreat operation, the light emitter section 140 is in a predetermined pattern. This is control information for continuing the blinking operation of 140 until the backward operation is canceled.
That is, the operation pattern in which the light emitter 140 is first flashed twice and then three times, and then the light emitter 140 is flashed twice and then three times within a predetermined time until the backward operation instruction is released. This is information for continuing the operation pattern of blinking twice and blinking three times.

The wing / tilt opening / closing blinking control information is information to be referred to when the control unit 110 determines that a wing / tilt opening / closing operation instruction has been given, and the light emitting unit 140 is released until the wing / tilt opening / closing operation instruction is released. This is information for continuing the blinking operation of. That is, when a wing / flapping opening / closing operation is performed, the light-emitting body 140 is first blinked n times (n is a natural number), for example, twice at predetermined time intervals, and then the retreat is performed during the wing / flapping opening / closing operation. The control information is another pattern different from the pattern for continuing the blinking operation of the light emitting unit 140 until the wing / flapping opening / closing operation is released.
That is, the operation pattern in which the light-emitting body 140 is first blinked twice and then the light-emitting body 140 is blinked twice within a predetermined time is continued until the wing / flapping opening / closing operation instruction is released. This is information for making it happen.

The operation detection unit 130 has a function of detecting the operation status of the vehicle body 10 and sending the detection and operation status to the control unit 110 as detected operation information. That is, the operation detection unit 130 detects whether the vehicle body 10 has been operated to move forward, to be operated backward, to be operated to blink a hazard, or to be operated to open or close the wings or to open and close the detection operation information. It has a function of sending.

The light emitter section 140 is composed of a plurality of light emitters 141, 142, 143, 144, 145, 146 provided at positions that are visible from the outside of the vehicle body 10, and is specific to the vehicle body 10. A predetermined blinking operation is performed under the control of the control unit 110 according to an operation. Here, with the driver's seat as the starting point, the light emitting body 141 is provided on the front left side of the cab body 12 (that is, on the right side when viewed from the front side of the vehicle body 10), and the light emitting body 142 is on the front right side of the cab body 12. (I.e., the left side of the vehicle body 10 when viewed from the front side), the light emitter 143 is provided on the left side surface of the wing body 14 (the right side surface when viewed from the front side), and the light emitter 144 is the right side surface of the wing body 14. The light-emitting body 145 is provided on the left side surface when viewed from the front side, and is provided on the lower left side (left rear part) of the rear door 14g located on the left side when viewed from the rear of the vehicle body 10, that is, on the lower part of the gate frame. The body 146 is provided on the lower right side (right rear part) of the rear door 14g located on the right side when viewed from the rear of the vehicle body 10, that is, on the lower portion of the gate frame.
Of course, the light emitting bodies 141, 142, 145, 146 may also be used as a conventional hazard lamp. In other words, the conventional hazard lamp may be functionally configured as the light emitters 141, 142, 145, 146. Further, as the light emitter, for example, a halogen lamp, a discharge lamp, or an LED lamp used in a conventional vehicle is assumed, but it is needless to say that other kinds of light sources may be used.

The operation of the above configuration will be described below.
When the backward operation is selected for the vehicle body 10 (see the back gear in step 300 of FIG. 3), the operation detection unit 130 detects the backward operation, so the control unit 110 refers to the memory 120 and the light emitter unit 140. Will be controlled so that it blinks when moving backward.

That is, first, the control unit 110 blinks the light emitting unit 140 twice at predetermined time intervals (step S302).

Subsequently, the control unit 110 blinks the light emitting unit 140 three times within a predetermined time (step S304). While the control unit 110 determines that the backward operation is being performed (Y in step S306), the light emitter unit 140 continues to blink twice and blink three times (steps S302 and S304).

When the backward movement operation is canceled (N in step S306), the control unit 110 turns off the light emitter unit 140 (step S320), and the series of processing ends.

Here, it is preferable that the series of blinking operations of the light emitting unit 140 be controlled to blink as follows, but it goes without saying that other blinking operation patterns may be used.
That is, in step S302, the light emitter unit 140 is controlled to blink in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 100 msec. In the following step S304, the light emitter unit 140 performs blink control in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 1000 msec.

Next, when the wing / tilt opening / closing operation is selected for the vehicle body 10 (see wing / tilt in step 300), the operation detecting unit 130 detects the wing / tilting opening / closing operation, so the control unit 110 causes the memory. With reference to 120, the light emitter unit 140 is controlled to perform a blinking operation at the time of wing / flapping opening / closing operation.

That is, first, the control unit 110 blinks the light emitter unit 140 twice at predetermined time intervals (step S312).

Subsequently, the control unit 110 blinks the light emitting unit 140 twice within a predetermined time (step S314). While the control unit 110 determines that the wing / flapping opening / closing operation is being performed (Y in step S316), the light emitting unit 140 continues to blink twice (step S314).

When the operation of opening / closing the wing / flipping is released (N in step S316), the control unit 110 turns off the light emitter unit 140 (step S320), and the series of processing ends.

Here, although it is preferable to control the series of blinking operations of the light emitting unit 140 as follows, it is needless to say that other blinking operation patterns may be used.
That is, in step S312, the light emitting unit 140 is controlled to blink in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 800 msec. In the following step S314, the light emitter section 140 is controlled to blink in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 800 msec.

According to the above-described embodiment, it is possible to visually notify the surroundings of the operation state of the wing / flapping opening / closing operation not only when the vehicle retreats but also when the vehicle is stopped, through the light emitting unit 140, to alert the surroundings and improve safety. Can be achieved.

Further, according to the above-described embodiment, it is sufficient that the light emitting unit 140 is controlled by the control unit 110 so as to blink with a different light emitting pattern for each operation, and it is easy without significantly changing the conventional hazard lamp mechanism and the like. Therefore, it is practical, economical and useful. Further, since it is different from the normal blinking operation of the hazard lamp, there is no misunderstanding that an emergency situation occurs.

That is, when the retreat operation is performed, the light emitter section 140 is first blinked m times (m is a natural number), for example, twice at a predetermined time interval, and then during the retreat operation, the light emitter section 140 is in a predetermined pattern. This is control information for continuing the blinking operation of 140 until the backward operation is canceled.
That is, the operation pattern in which the light emitter 140 is first flashed twice and then three times, and then the light emitter 140 is flashed twice and then three times within a predetermined time until the backward operation instruction is released. This is information for continuing the operation pattern of blinking twice and blinking three times.

The body 146 is provided on the lower right side (right rear part) of the rear door 14g located on the right side when viewed from the rear of the vehicle body 10, that is, on the lower portion of the gate frame.
Of course, the light emitters 141, 142, 145, 146 may also be used as a conventional hazard lamp. In other words, a conventional hazard lamp may be functionally configured as the light emitters 141, 142, 145, 146. Further, as the light emitter, for example, a halogen lamp, a discharge lamp, or an LED lamp used in a conventional vehicle is assumed, but it is needless to say that other types of light sources may be used.

The alarm sound generation unit 160 is provided so as to generate an alarm sound and a notification sound (synthetic sound) toward the outside of the vehicle body 10, and controls the control unit 110 according to a specific operation on the vehicle body 10. Below, an alarm sound and a notification sound are generated. In particular, the control unit 110 controls the control unit 110 to generate an alarm sound or a notification sound for notifying that the wing / tilt opening / closing operation is being performed in conjunction with the blinking operation of the light emitter unit 140 during the wing / tilt opening / closing operation. The function is configured to be performed.

The operation of the above configuration will be described below.
When the backward operation is selected with respect to the vehicle body 10 (see the back gear in step 500 of FIG. 5), the operation detection unit 130 detects the backward operation, so the control unit 110 refers to the memory 120 and the light emitter unit 140. Will be controlled so that it blinks when moving backward.

That is, first, the control unit 110 blinks the light emitting unit 140 twice at a predetermined time interval (step S502).

Subsequently, the control unit 110 blinks the light emitting unit 140 three times within a predetermined time (step S504). While the control unit 110 determines that the backward operation is being performed (Y in step S506), the light emitting unit 140 continues to blink twice and blink three times (steps S502 and S504).

When the backward operation is canceled (N in step S506), the control unit 110 turns off the light emitting unit 140 (step S520), and the series of processes is ended.

Here, it is preferable that the series of blinking operations of the light emitting unit 140 be controlled to blink as follows, but it goes without saying that other blinking operation patterns may be used.
That is, in step S502, the light emitter unit 140 is controlled to blink in the order of lighting for 200 msec, extinguishing for 100 msec, lighting for 200 msec, and extinguishing for 100 msec. In the following step S504, the light emitter unit 140 performs blinking control in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 1000 msec.

Next, when the wing / tilt opening / closing operation is selected for the vehicle body 10 (wing / tilt at step 500), the operation detecting unit 130 detects the wing / tilting opening / closing operation, and therefore the control unit 110 causes the memory 120 to operate. The light emitting unit 140 is controlled so as to perform a blinking operation at the time of the wing / flapping opening / closing operation, and the alarm sound generating unit 160 is interlocked to notify that the wing / flapping opening / closing operation is being performed. It will be controlled to generate various warning sounds and notification sounds.

That is, first, the control unit 110 blinks the light emitting unit 140 twice at predetermined time intervals (step S512). At this time, an alarm sound and a notification sound are generated at predetermined time intervals in conjunction with each other.

Subsequently, the control unit 110 blinks the light emitting unit 140 twice within a predetermined time (step S514). While the control unit 110 determines that the wing / tilt opening / closing operation is being performed (Y in step S516), the light emitting unit 140 continues to blink twice. Similarly, the alarm sound and the notification sound are continuously generated at predetermined time intervals in conjunction with each other.

When the operation of opening / closing the wing is released (N in step S516), the control unit 110 turns off the light emitting unit 140 and stops the generation of the alarm sound and the notification sound (step S520), and the series of processing is performed. It ends.

Here, although it is preferable to control the series of blinking operations of the light emitting unit 140 as follows, it is needless to say that other blinking operation patterns may be used.
That is, in step S512, the light emitter unit 140 performs blink control in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 800 msec. In the following step S514, the light emitter unit 140 is controlled to blink in the order of lighting for 200 msec, turning off for 100 msec, lighting for 200 msec, and turning off for 800 msec.

Further, the generation of the linked alarm sound by the alarm sound generation unit 160 is controlled so as to generate the buzzer sound in accordance with the blinking operation pattern of the light emitting unit 140 described above, but is not limited thereto. . Alternatively, control may be performed such that a notification voice indicating that work is in progress is generated at predetermined time intervals.

According to the above-described embodiment, not only when the vehicle retreats, but also when the vehicle is stopped, the operation status of the wing / flapping opening / closing can be visually notified to the surroundings through the light emitter section 140, and the surroundings can be notified through the alarm sound generating section 160. Since it can be notified aurally, it is possible to further alert the surroundings and improve safety.

Further, according to the above-described embodiment, it is sufficient that the light emitting unit 140 is controlled by the control unit 110 so as to blink with a different light emitting pattern for each operation, and it is easy without significantly changing the conventional hazard lamp mechanism and the like. Therefore, it is practical, economical and useful.

Next, a modified example of this embodiment will be described. The same parts and the same functions as those of the embodiment are designated by the same reference numerals and the description thereof will be omitted.

In this modification, on / off control and volume adjustment of generation of an alarm sound or a notification sound for notifying that the wing / flapping opening / closing operation is being performed from the alarm sound generation device 160 at the time of opening / closing the wing / flapping. It is possible to control.

That is, the on / off operation of the generation of the alarm sound or the notification sound is performed by the volume detection switch (not shown, hereinafter referred to as SW) provided inside the vehicle body 10 and the operation detection unit that detects the variable state of the SW. 130 is detected and controlled under the control of the control unit 110 so as to control the generation of a notification sound according to the operation. Referring to FIG. 6, the action of the backward operation is the same as that of the above-described embodiment, and the explanation of the action will be omitted.

When the wing / tilt opening / closing operation is selected for the vehicle body 10 (see wing / tilt in step 600), the operation detecting unit 130 detects the wing / tilting opening / closing operation, so the control unit 110 refers to the memory 120. Then, the light emitter section 140 is controlled so as to perform a blinking operation at the time of the wing / tilt opening / closing operation, and the alarm sound generating section 160 is controlled so as to generate an alarm sound or a notification sound in conjunction therewith. At this time, since the operation detection unit 130 detects the ON / OFF switching of the SW and the variable state, the alarm sound generation unit 160 is controlled by the control unit 110 to generate / generate the alarm sound or the notification sound according to the situation. In the case of no occurrence and occurrence, an alarm sound with a controlled volume will be generated.

That is, first, the control unit 110 blinks the light emitting unit 140 twice at a predetermined time interval (step S612). At this time, if the SW is in the ON state, an alarm sound or a notification sound is generated at a predetermined time interval with the volume controlled in conjunction. If the SW is in the off state, no alarm sound or notification sound is generated.

Subsequently, the control unit 110 blinks the light emitting unit 140 twice within a predetermined time (step S614). While the control unit 110 determines that the wing / tilt opening / closing operation is being performed (Y in step S616), the light emitting unit 140 continues to blink twice. At this time, if the SW is in the ON state, an alarm sound or a notification sound is generated at a predetermined time interval with the volume controlled in conjunction. If the SW is in the off state, no alarm sound or notification sound is generated.

When the operation of opening / closing the wings / canceling is released (N in step S616), the control unit 110 turns off the light emitting unit 140 and stops the generation of the alarm sound and the notification sound (step S620), and the series of processing is performed. It ends.

According to this modification, since it is possible to control the generation of the alarm sound and the notification sound, the volume can be reduced or turned off when working in a quiet environment such as at night or in a residential area, which causes noise. It will eliminate your worries. Further, in a place with a large amount of traffic, a construction site, etc., the volume can be increased so that the surroundings can be surely alerted.

(Third Embodiment)
Subsequently, a third embodiment of the present invention will be described. The same parts and functions as those of the first embodiment and the second embodiment and the modified examples will be described with the same reference numerals.

The vehicle notification control system 100 according to the present embodiment, as shown in FIG. 8, is directly connected to the vehicle body 10 of a truck including a cab body 12 and a wing body (cargo bed) 14 for cargo handling, and the vehicle body 10. The trailer 16 has been installed. The wing body 14 is provided with wing side panels 14a and 14d, side surface front tilts 14b and 14e, side surface rear tilts 14c and 14f, and a rear door 14g that can be opened and closed. Further, the trailer 16 is provided with wing side panels 16a, 16d, side surface front tilts 16b, 16e, side surface rear tilts 16c, 16f, and a rear door 16g so as to be openable and closable.

Further, the vehicle notification control system 100 includes, as shown in FIG. 7, a control unit 110, a memory 120, an operation detection unit 132, a light emitter unit 140, an alarm sound generation unit 160, a transmission unit 170, a reception unit 180, and a second unit. A light emitter 190 is provided internally, and each is connected via a signal line 150. Then, the vehicle notification control system 100 first blinks twice at a predetermined time interval during the backward movement operation of the vehicle body 10 and then blinks three times, and during the backward movement operation, blinks twice in a predetermined pattern, that is, twice. It has a function of controlling the light emitter section 140 and the second light emitter section 190 so that the blinking operation is continued in the order of blinking once and after the backward operation is completed, the blinking operation is ended and the light is turned off. On the other hand, the vehicle notification control system 100 first blinks twice at a predetermined time interval during an operation different from the backward operation of the vehicle body 10, and then blinks twice during the different operation, which is a different pattern from the backward operation. It has a function of controlling the light emitter section 140 and the second light emitter section 190 so that the operation is continued and the operation of blinking twice is ended and the light is turned off after the operation is completed. In addition, when the operation is different from the backward operation, the alarm sound is generated in conjunction with the blinking operation.

The control unit 110 has a function of controlling the entire system by referring to predetermined program information stored in the memory 120. In addition, the control unit 110 refers to the memory 120 for blinking operation information that matches the detection information based on the detection information (detection operation information or connection detection information described below) from the operation detection unit 132, and the light emitter unit 140 and It has a function of controlling the blinking operation of the second light emitter 190 and the generation of an alarm sound by the alarm sound generator 160.

It has a storage area such as 120d.

Here, the blinking operation information stored in the blinking operation information area 120c is blinking control information for performing a blinking operation according to an operation on the vehicle body 10 or the trailer 16 which the control unit 110 refers to. That is, the blinking control information is hazard blinking control information, backward blinking control information, and, for example, blinking control information during wing / flapping opening / closing, which is an operation different from that during backward movement. The control information corresponding to the operation different from the backward movement is not limited to the blink control information at the time of opening / closing the wing / tilt, but other control information such as blink control information at the time of opening / closing the door or PTO (Power Take-Off) operation It goes without saying that it may be blinking control information or the like.

The hazard blinking control information is information to be referred to by the control unit 110 when it is determined that the operation instruction for blinking the hazard lamp has been issued, and the light emitting unit 140 and the first unit are set at constant time intervals until the operation instruction is released. This is information for continuing the blinking operation of the second light emitter 190.

The backward flashing control information is information to be referred to by the control unit 110 when it is determined that a backward operation instruction has been issued, and is stored in the light emitter section 140 and the second light emitter section 190 until the backward operation instruction is released. This is information for continuing the blinking operation. That is, when the backward operation is performed, the light emitter section 140 and the second light emitter section 190 are first blinked m times (m is a natural number), for example, twice at a predetermined time interval, and then the backward operation is performed in advance. This is control information for continuing the blinking operation of the light emitter section 140 and the second light emitter section 190 in a predetermined pattern until the backward operation is released.
That is, the light emitter section 140 and the second light emitter section 190 are blinked twice first and then three times, and then the light emitter section 140 and the second light emitter section 190 are blinked twice within a predetermined time. This is information for continuing the operation pattern of blinking twice, and then blinking three times until the backward operation instruction is released.

The wing / tilt opening / closing blinking control information is information to be referred to when the control unit 110 determines that a wing / tilt opening / closing operation instruction has been given, and the light emitting unit 140 is released until the wing / tilt opening / closing operation instruction is released. And information for continuing the blinking operation of the second light emitter unit 190. That is, when a wing / flapping opening / closing operation is performed, the light emitter section 140 and the second light emitter section 190 are first blinked n times (n is a natural number), for example, twice at predetermined time intervals, and then the wing Control information for continuing the blinking operation of the light emitter section 140 and the second light emitter section 190 during the swing opening / closing operation in a different pattern from the above-described backward movement pattern until the wing / flapping opening / closing operation is released. is there.
That is, the operation pattern in which the light-emitting body 140 and the second light-emitting body 190 are first blinked twice and then the light-emitting body 140 and the second light-emitting body 190 are blinked twice within a predetermined time is the wing. This is information for continuing the operation pattern of blinking twice until the opening / closing operation instruction is canceled.

The alarm sound control information stored in the alarm sound information area 120d is alarm sound control information for generating an alarm sound or a notification sound according to an operation on the vehicle body 10 which the control unit 110 refers to. In particular, this is information that is generated when the wing / flapping opening / closing operation is performed.

The operation detection unit 132 has a function of detecting the operation status of the vehicle body 10 and sending the detection and the operation status to the control unit 110 as detection operation information. That is, the operation detection unit 132 detects whether the vehicle body 10 has been operated to move forward, to be operated backward, to be operated to blink hazards, or to be operated to open / close the wings / flaws, and to detect the detected operation information. It has a function of transmitting.
Also. The operation detection unit 132 has a function of detecting whether the trailer 16 is directly or indirectly connected.

Of course, the light emitters 141, 142, 145, 146 may also be used as a conventional hazard lamp. In other words, a conventional hazard lamp may be functionally configured as the light emitters 141, 142, 145, 146. Further, as the light emitter, for example, a halogen lamp, a discharge lamp, or an LED lamp used in a conventional vehicle is assumed, but it is needless to say that other types of light sources may be used.

The alarm sound generation unit 160 is provided to generate an alarm sound or a notification sound toward the outside of the vehicle body 10, and under the control of the control unit 110 in response to a specific operation of the vehicle body 10, the alarm sound generation unit 160. Or a notification sound is generated. In particular, when the wing / flapping opening / closing operation is performed, an alarm sound or a notification sound is generated in conjunction with the blinking operation of the luminous body section 140 and the second luminous body section 190 to notify that the wing / flapping opening / closing operation is being performed. The functional unit is configured to be controlled by the control unit 110.

The transmission section 170 is provided on the vehicle body 10 side and is functionally configured to wirelessly transmit the control information of the control section 110 to the second light emitter section 190 on the trailer 16 side connected thereto.
Since the operation detection unit 132 is configured to detect that the trailer 16 is connected to the vehicle body 10 and send the connection detection information to the control unit 110, the control information from the control unit 110 is sent to the transmission unit. It goes without saying that the transmitting unit 170 may be provided on the trailer 16 side if the 170 can be recognized.

The receiving unit 180 is provided on the trailer 16 side and has a function of receiving control information from the control unit 110 transmitted from the transmitting unit 170 and transmitting this received information to the second light emitting unit 190.

The second light emitter section 190 is provided on the trailer 16 side at a position where it can be seen from the outside, and is composed of a plurality of light emitters 192, 194, 196, 198, and based on the information from the receiver section 180. It is functionally configured to perform a blinking operation. That is, a predetermined blinking operation is performed in synchronization with the light emitter section 140 under the control of the control section 110 in response to a specific operation on the vehicle body 10 or the trailer 16. Here, the light emitting body 192 is provided on the right side surface (below the side surface front tilt 16b) when viewed from the front side of the vehicle body 10, and the light emitting body 194 is the left side surface (side surface when viewed from the front side of the vehicle body 10). The light emitter 196 is provided on the lower side of the front door 16g), the light emitter 196 is provided on the lower left side (left rear part) of the rear door 16g, and the light emitter 198 is provided on the lower right side (right rear part) of the rear door 16g.
Of course, the light emitters 196 and 198 may also be used as a conventional hazard lamp. In other words, a conventional hazard lamp may be functionally configured as the light emitters 196 and 198. Further, as the light-emitting body, for example, one used in a conventional trailer such as a halogen lamp, a discharge lamp or an LED lamp is assumed, but it goes without saying that another type of light source may be used.

Regarding the above configuration, the control operation of the light emitter and the alarm sound when the trailer 16 is connected will be described below.

When the operation detector 132 detects that the trailer 16 is directly connected to the vehicle body 10 (Y in step 902 in FIG. 9), the controller 110 causes the light emitter 140 and the second light emitter 190 to operate. On the other hand, various flashing operation controls are performed according to the operation status (for example, backward operation, wing / flapping opening / closing operation).

That is, for the light emitter section 140 on the vehicle body 10 side, for example, blink control of a predetermined pattern is performed according to the backward operation or the wing / flapping opening / closing operation as shown in FIG. 6 (Y in step S904, S908). This blinking control continues while the operation is continuing (N in step S910) (step S908). When the operation is canceled / finished (Y in step S910), the blinking control, that is, the blinking operation is finished (step S912). The same applies to the alarm sound generation.

Regarding the light emitters 192, 194, 196, 198 on the trailer 16 side (N in step S904), a predetermined pattern in synchronization with the light emitter unit 140 as shown in FIG. The blinking operation of is controlled wirelessly (step S914). The blinking control by wireless continues in synchronization with the light emitting unit 140 while the operation is continuing (N in step S916) (step S914). When the operation is canceled / finished (Y in step S916), the blinking control, that is, the blinking operation is finished at the same time as the light emitter unit 140 (step S912).

According to the above-described embodiment, the light-emitting body on the trailer 16 side can be controlled by a wireless connection without being electrically connected to the trailer 16 via a cable as in the conventional case. It is not necessary to provide, and is versatile.

In the above embodiment, one trailer 16 is connected to the vehicle body 10. However, the present invention is not limited to this, and another trailer is connected to the trailer 16 so that the light emitters of the other trailers are also connected to the light emitter section 140. Of course, the blinking control may be performed in synchronization. In this case, the operation detection unit 132 detects a direct or indirect connection state with the vehicle body 10, and the control unit 110 performs blinking control via the respective reception units. In other words, a plurality of trailers may be connected to each other so that each light emitter is controlled to blink in synchronization with the light emitter unit 140, and the structure is within the scope of the present invention.

Further, in each of the above-described embodiments and modified examples, blinking operation and alarm sound control are collectively performed by one control unit, but a function is incorporated into a control mechanism that controls the entire vehicle body, or Needless to say, it is within the scope of the present invention to appropriately control the functions of the control unit in a distributed manner.

For example, in FIG. 10, the control unit is divided into two, and the blinking control of the light emitter is performed during hazard operation, backward operation, and wing / flapping opening / closing operation. That is, a control unit specialized for opening / closing the wings / flaws is newly provided, and in cooperation with a control unit that is in charge of other controls, blinking control of the light emitter is performed so that both functions as one control mechanism. It was done. In the figure, an arrow indicated by a two-dot chain line indicates a flow of information by wireless, and an arrow indicated by a dotted line indicates a flow of information via a cable.
