On the other hand, in the technique described in Patent Document 1, an emergency signal generating device that generates one from a plurality of visual patterns according to a user's selection has been proposed.
Japanese Patent No. 2604927

  However, the technique described in Patent Document 1 does not particularly refer to a warning method when approaching an intersection. Therefore, like a general emergency vehicle, only the siren sound is changed to notify the approach of the emergency vehicle and there is room for improvement in the visual notification method of the presence of the emergency vehicle.

  The present invention has been made in consideration of the above facts, and an object thereof is to visually and audibly notify the presence of an emergency vehicle according to the situation.

In order to achieve the above object, the invention according to claim 1 is used in a first warning mode used in an emergency run to notify the presence of an emergency vehicle to the surroundings, and in an emergency different from the first warning mode. An instruction means for outputting an instruction signal for instructing at least two kinds of warning modes including the second warning mode, and a warning sound used in the first warning mode for informing the surrounding of the presence of the emergency vehicle. includes a sub siren that generates a warning sound to be used in the main siren and the second alert mode to generate a warning sound generating means for generating an alarm sound corresponding to the two kinds of warning mode based on the previous SL instruction signal In order to notify the presence of an emergency vehicle to the surroundings, a first lighting pattern that is predetermined in correspondence with the first warning mode and a second lighting pattern that is predetermined in correspondence with the second warning mode In is possible lighting warning and warning light that lights in the lighting pattern corresponding to the two kinds of warning mode, when the instruction signal representative of said first warning mode from the instruction means is output by the main siren The warning light is controlled so as to generate a sound and light up in the first lighting pattern, and when the instruction signal indicating the second warning mode is output from the instruction means, a warning sound is generated by the sub siren. And a control means for controlling the warning lamp so as to be generated and lit with the second lighting pattern .

According to the first aspect of the present invention, the instructing means uses the first warning mode used during emergency traveling to notify the presence of the emergency vehicle, and the second warning mode used during an emergency different from the first warning mode. An instruction signal for instructing at least two types of warning modes including is output.

The warning sound generating means includes a main siren that generates a warning sound used in the first warning mode and a secondary siren that generates a warning sound used in the second warning mode in order to notify the surroundings of the presence of the emergency vehicle. A warning sound corresponding to the warning mode is generated based on the instruction signal output from the means . The audible beep, for example, a general emergency travel warning sound to be used for a warning sound to be used when the vehicle is stopped, it is possible to apply a warning sound or the like to be used for emergency running a and at an intersection approach or the like.

The warning light can be lit in a first lighting pattern predetermined in correspondence with the first warning mode and a second lighting pattern predetermined in correspondence with the second warning mode in order to notify the presence of the emergency vehicle, Lights with a lighting pattern corresponding to the warning mode based on the instruction signal output from the instruction means. As the lighting pattern, for example, a lighting pattern used during general emergency traveling, a lighting pattern used during stopping, a lighting pattern used during emergency traveling and entering an intersection, and the like can be applied.
The control means controls the warning light so that the warning sound is generated by the main siren and is lit in the first lighting pattern when the instruction signal indicating the first warning mode is output from the instruction means. When the instruction signal indicating the second warning mode is output from the warning light, the warning light is controlled so that a warning sound is generated by the secondary siren and the second lighting pattern is turned on.

That is, since the combination of the warning sound and the lighting pattern can be switched according to the instruction signal, the warning sound is set to a different type of warning sound according to the instruction signal, and accordingly the lighting pattern of the warning light is set to a different type. The lighting pattern can be changed, for example, the presence of an emergency vehicle can be notified by a predetermined warning sound and a predetermined lighting pattern during emergency traveling, and the warning sound and the lighting pattern can be different when approaching an intersection. Therefore, the presence of the emergency vehicle can be easily recognized by the surroundings (for example, other vehicles, pedestrians, etc.), and in particular, a rear-end collision from other vehicles can be avoided. Therefore, the presence of the emergency vehicle can be visually and audibly notified according to the situation.

At this time, the warning light is constituted by an array of a plurality of LED groups as in the invention described in claim 2, and the control means outputs an instruction signal representing the first warning mode from the instruction means . In the second warning mode , the LED groups are sequentially turned on from the vehicle center side to the outside along the vehicle width direction, and the warning lights are turned on so as to turn on the lighting patterns that appear to rotate on the left and right sides of the vehicle. When the instruction signal representing the above is output , the warning lamp may be controlled so that the LED group blinks and lights up in a lighting pattern that lights up in a fan shape. For example , it is possible to change the light during normal emergency driving and when approaching an intersection, and when the warning light is lit in the second lighting pattern, it flashes in a fan shape, so that a wide field of view can be emitted. The presence of an emergency vehicle can be notified to the surroundings by reflection from surrounding buildings and roads.

As the instruction signal output from the instruction means, for example, as in the invention according to claim 3, the auxiliary siren instruction means for instructing the generation of the auxiliary siren, the direction indicator, and the navigation for outputting the intersection information. When the intersection signal obtained from at least one of the devices is included and the intersection signal is output from the instruction means , the warning sound generating means generates a warning sound by the sub siren and the control means is the second lighting You may make it control a warning light so that it may light with a pattern. That is, the transition to the second warning mode can be performed from various aspects. Moreover, forgetting operation etc. can be reliably prevented by combining a plurality.

Further, as in the invention described in claim 4, the indicating means outputs an instruction signal for instructing at least three types of warning modes further including a third warning mode used when the vehicle is stopped , When it is possible to further illuminate with a predetermined third lighting pattern corresponding to the three warning modes and an instruction signal for instructing the third warning mode is output from the instruction means , the warning sound generating means May be stopped and the control means may control the warning lamp so as to light up in the third lighting pattern. In this case, the warning light is configured by an array of a plurality of LED groups as in the invention described in claim 5 , and the control means is arranged along the vehicle width direction when lit in the third lighting pattern. Then, the warning lamps may be controlled so that the LED groups are sequentially turned on and turned on in a lighting pattern that appears to rotate in the entire vehicle width direction. As a result, it is possible to obtain a lighting pattern that is gentle to the surrounding living environment.

Further, when the instruction signal includes an instruction signal for instructing the third warning mode, the instruction signal detects the parking range of the shift lever or the operation of the parking brake as in the sixth aspect of the invention. comprise stop signal obtained from the detecting means, when detecting the stop vehicle signal, the alarm generating means stops generating the warning sound, the control means, a warning lamp to illuminate the third lighting pattern May be controlled . As a result, the warning light can be lit in the third lighting pattern when the vehicle is stopped.

On the other hand, as the warning lamp, as in the invention according to claim 7 , a plurality of LED groups having a plurality of LED light sources are arranged along the vehicle width direction, and the plurality of LED groups are arranged in a plurality. You may make it include the fan arrangement | sequence with which LED group was arranged in fan shape along a vehicle width direction, and the center direction arrangement | sequence where a some LED group was arranged so that an optical axis might face the vehicle center direction. That is, the warning lamp can be turned on with a wide field of view by the LED group arranged in a fan arrangement, and the irradiation range of light viewed from the obliquely forward direction can be widened by the arrangement in the center.

In the warning light, as in the invention according to claim 8, the plurality of LED groups are arranged in three stages in the vehicle vertical direction, the upper and lower stages are the fan arrangement, and the middle stage is the central arrangement. May be applied.
As in the ninth aspect of the invention, when an instruction signal indicating the second warning mode is output from the instruction means when the vehicle stops, the warning sound generating means generates a warning sound by the sub siren and controls The means may control the warning light so as to be lit in the second lighting pattern, and as in the invention according to claim 10, the instruction means further includes a third warning mode used when the vehicle is stopped. An instruction signal for instructing at least three types of warning modes is output, and the warning lamp can be further lit with a third lighting pattern determined in advance corresponding to the third warning mode. When the instruction signal indicating the warning mode is output, the warning sound generation means may stop the warning sound and the control means may control the warning light so that it is lit in the third lighting pattern.

  As described above, according to the present invention, a warning sound of a predetermined type corresponding to the warning mode based on the instruction signal for instructing the type of the warning mode for notifying the surroundings of the presence of the emergency vehicle. When the warning light is turned on with a predetermined lighting pattern corresponding to the warning mode, the warning sound is made to have a different type of warning sound according to the instruction signal, and the warning light lighting pattern is different accordingly. Since the lighting patterns can be of various types, there is an effect that the presence of the emergency vehicle can be visually and audibly notified according to the situation.

  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

When the beacon 14 is lit in the normal lighting pattern, the main siren 20 can be sounded at the same time. In an emergency, the sub siren 28 is sounded at the same time. Alternatively, the sub siren 28 can be sounded simultaneously. Specifically, the control unit 15 of the beacon 14 changes the lighting pattern according to the states of the main siren switch 22, the shift position switch 26, and the sub siren switch 30.

  In other words, the diffused warning lamp device 10 according to the present embodiment has a plurality of warning modes consisting of combinations of lighting patterns and warning sounds for notifying the presence of an emergency vehicle. Combination of lighting pattern and sound according to warning mode such as normal warning mode to be used, emergency warning mode to be used during emergency driving when crossing an intersection, etc., and warning mode to be used when stopped The adjustment is switched.

  Then, the lighting pattern of the beacon 14 of the diffuse type warning lamp device 10 concerning embodiment of this invention is demonstrated.

  As described above, the diffused warning lamp device 10 according to the embodiment of the present invention notifies the presence of an emergency vehicle when passing through an intersection or the like, and a normal lighting pattern for notifying the presence of an emergency vehicle. There are three types of lighting patterns: an emergency lighting pattern and a stationary lighting pattern for notifying the presence of an emergency vehicle while the vehicle is stopped.

  FIG. 4 is a diagram for explaining a normal lighting pattern, and FIG. 5 shows the lighting timing of each channel (LED group 16). In addition, the channel (CH) in FIG. 4 respond | corresponds to each LED group 16 of the beacon 14, and attaches | subjects a number in order seeing from the vehicle front.

Specifically, as shown in FIG. 4, the LED group 16 of 3CH, 4CH, 8CH, 9CH, 13CH, and 14CH is A (ms) on, A (ms) off, A (ms) on, and A (ms) off. Next, the LED group 16 of 2CH, 3CH, 4CH, 5CH, 8CH, 9CH, 12CH, 13CH, 14CH, and 15CH is A (ms) on, A (ms) is off, A (ms) is on, A (ms) The LED group 16 of 1CH, 2CH, 5CH, 6CH, 7CH, 10CH, 11CH, 12CH, 15CH, and 16CH is turned on, A (ms) is turned off, A (ms) is turned off, A (ms) is turned on, and A (ms ) Is turned off, and then 1CH, 6CH, 7CH, 10CH, 11CH, and 16CH are turned on by A (ms), turned off by A (ms), turned on by A (ms), and turned off by A (ms). And by repeating this, it lights so that the beacon 14 is rotating on the left and right with the vehicle center of the beacon 14 as a boundary.

  That is, the lighting timing of each LED group 16 becomes the timing shown in FIG. 5 (A) when the LED groups 16 of 3CH, 4CH, 8CH, 9CH, 13CH, and 14Ch become the same lighting timing, respectively, 2CH, 5CH, and 12CH. 15CH LED groups 16 have the same lighting timing and the timing shown in FIG. 5B, and 1CH, 6CH, 7CH, 10CH, 11CH, and 16CH have the same lighting timing in FIG. 5C. It becomes the timing shown.

  FIG. 6 is a diagram for explaining an emergency lighting pattern, and FIG. 7 shows the lighting timing of each channel (LED group 16). Note that the channels (CH) in FIG. 6 correspond to the LED groups 16 of the beacon 14 and are numbered in order as viewed from the front of the vehicle.

  The lighting pattern in an emergency is a lighting pattern in which the LED group 16 is blinked to light in a fan shape. Specifically, as shown in FIG. 6, all LED groups 16 of the beacons 14 of 1 to 16 CH are turned on by A (ms), B (ms) is turned off, A (ms) is turned on, B (ms) is turned off, The LED group 16 of 3CH, 4CH, 8CH, 9CH, 13CH, and 14CH is turned on by A (ms), B (ms) is turned off, A (ms) is turned on, and B (ms) is turned off. And by this repetition, the beacon 14 repeats blinking entirely, and it lights so that blinking of the whole beacon 14 and some blinking may be repeated.

  That is, the lighting timing of each LED group 16 is shown in FIG. 7A, with the LED groups 16 of 1CH, 2CH, 5CH, 6CH, 7CH, 10CH, 11CH, 12CH, 15CH, and 16CH having the same lighting timing. At the timing, the LED groups 16 of 3CH, 4CH, 8CH, 9CH, 13CH, and 14CH have the same lighting timing and the timing shown in FIG.

  FIG. 8 is a diagram for explaining a lighting pattern when the vehicle is stopped. FIGS. 9 and 10 show the lighting timing of each channel (LED group 16). In addition, the channel (CH) in FIG. 8 corresponds to each LED group 16 of the beacon 14, and is numbered in order when viewed from the front of the vehicle.

  The lighting pattern when the vehicle is stopped is a lighting pattern in which the LED groups 16 are sequentially lit along the vehicle width direction and appear to rotate throughout the vehicle width direction. Specifically, as shown in FIG. 8, LED groups 16, 1CH, 7CH, 11CH LED groups 16, 1CH, 2CH, 7CH, 11CH, 12CH LED groups 16, 2CH, 3CH, 8CH, 12CH, 13CH LED groups 16, 3CH LED group 16, 4CH, 8CH, 9CH, 13CH, 14CH LED group 16, 4CH, 5CH, 9CH, 14CH, 15CH LED group 16, 5CH, 6CH, 10CH, 15CH, 16CH LED group 16, 6CH, 10CH, 16CH LED After the group 16 is turned on sequentially by C (ms), the D (ms) is turned off and the LED groups 16, 5CH, 6CH, 10CH, 15CH, 16CH LED groups 16, 4CH, 5CH, 9CH, 6CH, 10CH, 16CH, 14CH, 15CH LED groups 16, 3CH, 4CH, 8CH, 9CH, 13CH, 14 H LED group 16, 2CH, 3CH, 8CH, 12CH, 13CH LED group 16, 1CH, 2CH, 7CH, 11CH, 12CH LED group 16, 1CH, 7CH, 11CH LED group 16 sequentially in C (ms) After lighting, D (ms) is turned off. And by repeating this, the beacon 14 lights up so that the whole is rotating more slowly than usual.

  That is, the lighting timing of each LED group 16 is the same lighting timing for the LED groups 16 of 1CH, 7CH, and 11CH, as shown in FIG. 9A, and the LED group 16 of 2CH and 12CH is the same. The lighting timing becomes the timing shown in FIG. 9B, and the LED groups 16 of 3CH, 8CH, and 13CH become the same lighting timing, and the timing shown in FIG. 9C, and the LEDs of 4CH, 9CH, and 14CH. The group 16 has the same lighting timing and the timing shown in FIG. 10A, and the 5CH and 15CH LED groups 16 have the same lighting timing and the timing shown in FIG. , 16CH LED groups 16 have the same lighting timing, respectively. The timing shown in C).

  Next, the operation of the control unit 15 of the beacon 14 of the diffused warning lamp device 10 according to the embodiment of the present invention configured as described above will be described.

  FIG. 11 is a flowchart showing an example of the flow of operations performed by the control unit 15 of the beacon 14 of the diffused warning lamp device 10 according to the embodiment of the present invention.

  When the main siren switch 22 is turned on and the battery voltage is applied to the control unit 15 of the beacon 14, it is determined in step 100 whether or not the shift lever 26A is in the parking range. This determination is made by determining whether or not a parking signal is output from the shift position sensor 26 and input to the control unit 15 by the shift lever 26A being moved to the parking range, and if the determination is negative, a step is performed. If the result is affirmative, the process proceeds to step 110.

  In step 102, it is determined whether or not the auxiliary siren switch 30 is turned on. This determination is made by determining whether or not the auxiliary siren relay 32 is turned on when the auxiliary siren switch 30 is turned on and the battery voltage is input to the control unit 15. If the determination is negative, the process proceeds to step 104. If the result is affirmative, the process proceeds to step 106.

  In step 104, the beacon 14 is turned on in the normal lighting pattern, and the process proceeds to step 108. That is, when the sub siren switch 30 is not in the parking range and is turned off, the beacon 14 is turned on to the left and right with the vehicle center of the beacon 14 as a boundary to notify the surroundings of the presence of the emergency vehicle. The presence of the emergency vehicle is notified to the surroundings by the warning sound of the main siren 20. As a result, the presence of an emergency vehicle can be notified in the same manner as a conventional ambulance. At this time, when the switch for turning on the beacon 14 of the main siren switch 22 is turned on, only the beacon 14 is turned on without ringing the main siren 20.

  In Step 106, the beacon 14 is turned on in the emergency lighting pattern, and the process proceeds to Step 108. That is, when it is not in the parking range and the sub siren switch 30 is on, it is lit to repeat blinking of the entire beacon 14 and part of it, and is lit in a lighting pattern that stands out from the normal time, The auxiliary siren 28 notifies the surroundings of the presence of an emergency vehicle. For example, when the sub siren switch 30 is turned on when passing an intersection or the like, the beacon 14 is lit in the emergency lighting pattern, and the presence of an emergency vehicle can be notified by the sub siren 28. Thus, unlike conventional ambulances, in the event of an emergency when passing through an intersection, etc., not only the different warning sounds are switched, but also the lighting pattern is switched, so the passage around the intersection, etc. (around other vehicles, pedestrians, etc.) It can be made easy to recognize. In particular, a rear-end collision of another vehicle can be avoided. Furthermore, by turning on the lighting pattern of the beacon 14 so that the entire beacon 14 blinks and a part of it blinks, a wide field of view can be shined, and the presence of an emergency vehicle is reflected by reflection from surrounding buildings and roads. You can notify the surroundings.

  On the other hand, if the determination at step 100 is affirmative and the routine proceeds to step 110, it is also determined at step 110 whether or not the auxiliary siren switch 30 has been turned on. This determination is made by determining whether or not the sub siren relay 32 is turned on when the sub siren switch 30 is turned on and the battery voltage is applied to the control unit 15. If the determination is negative, the process proceeds to step 112. If the result is affirmative, the process proceeds to step 106 described above.

  In step 112, the beacon 14 is lit in the lighting pattern when the vehicle is stopped, and the process proceeds to step 108. That is, when the auxiliary siren switch 30 is off in the parking range, the beacon 14 is turned on so that the entire beacon is rotating more slowly than usual, and the presence of an emergency vehicle is notified to the surroundings by the main siren 20. Can do. Thus, when the vehicle is stopped, the beacon 14 can be illuminated with a visual pattern that is gentler to the surrounding living environment than other lighting patterns. At this time, when the switch for turning on only the main siren switch 22 with the beacon 14 is turned on, only the beacon 14 is turned on without ringing the main siren 20.

  In step 108, it is determined whether or not the main siren switch 22 is turned off. If the determination is negative, the process returns to step 100 and the above-described processing is repeated, and the determination in step 108 is affirmed. A series of processing ends.

  As described above, the diffused warning lamp device 10 according to the embodiment of the present invention includes a normal warning mode used during normal emergency driving, an emergency warning mode used during emergency when passing an intersection, and the like. And a warning mode used when the vehicle is stopped, generating a warning sound corresponding to the warning mode based on an instruction signal for instructing the warning mode, and a beacon 14 with a lighting pattern corresponding to the warning mode. Since it is lit, the presence of the emergency vehicle can be visually and audibly notified according to the situation such as normal emergency travel, emergency travel when passing an intersection, etc., and stopping.

  In the above embodiment, when an emergency lighting pattern is used when passing an intersection or the like, the control unit 15 of the beacon 14 switches the lighting pattern by detecting the usage state of the sub siren 28. However, the present invention is not limited to this. For example, an operation signal indicating a direction indicator operation instruction of a direction indicator or intersection information obtained from a navigation device is detected as an intersection signal, and a lighting pattern is switched. These may be used, or may be used in combination.

  For example, as shown in FIG. 12, a direction indicator 34 and a navigation device 36 are further connected to the sub siren relay 32, a sub siren generation instruction by the sub siren switch 28, and a direction indicator operation instruction by the direction indicator 34. In addition, since the auxiliary siren relay 32 is turned on by at least one of the intersection information obtained from the navigation device 36, not only the state of the auxiliary siren switch 30, but also the operation state of the direction indicator 34 and navigation An intersection can be detected from information obtained from the device 36 and the like, and an emergency lighting pattern can be easily obtained when passing through the intersection. Moreover, since it is possible to make an emergency lighting pattern from various aspects, it is possible to reliably prevent forgetting operation and the like.
