When the travel mode is “normal security”, the state determination between the police car 201 and the tracked vehicle 202 and the setting of the notification level may be performed.

  In the present embodiment, for example, the driving mode of the police car 201 is “emergency driving”, and the state determination between the police car 201 and the tracked vehicle 202 indicates that the driving speed V1 of the police car 201 is “0 km / hour or more and 80 km / hour”. When the traveling speed V2 of the tracked vehicle 202 is equal to or less than the traveling speed V1, the first mode is selected as the notification level in the notification level table 112B, and the tracked vehicle 202 When the traveling speed V2 exceeds the traveling speed V1, the second mode is selected as the notification level in the notification level table 112B. As a scene in which the first mode is selected, the chasing vehicle 202 enters a stop preparation, the passenger of the chasing vehicle 202 recognizes the presence of the police car 201, or the patrol car 201 detects the chasing vehicle 202. For example, when guiding safely. The scene in which the second mode is selected is when the passenger of the chasing vehicle 202 does not recognize the police car 201.

  In addition, when the driving mode of the police car 201 is “emergency driving”, the state determination between the police car 201 and the tracked vehicle 202 indicates that the running speed V1 of the police car 201 is “80 km / hour or more and less than 110 km / hour”. When the traveling speed V2 of 202 is the same as the traveling speed V1 or less than the traveling speed V1, the second mode is selected as the notification level in the notification level table 112B, and the traveling speed V2 of the tracked vehicle 202 is the traveling speed. When V1 is exceeded, the third mode is selected as the notification level in the notification level table 112B. As a scene in which the third mode is selected, the follow-up vehicle 202 enters a stop preparation, the passenger of the follow-up vehicle 202 recognizes the presence of the police car 201, or the police car 201 detects the follow-up vehicle 202. This is when the vehicle is being guided and is at a constant traveling speed.

  In addition, the driving mode of the police car 201 is “emergency driving”, the state determination between the police car 201 and the tracked vehicle 202 is that the driving speed V1 of the police car 201 is “110 km / hr or more”, and the driving speed of the tracked vehicle 202 is When V2 is less than the traveling speed V1, the notification level in the notification level table 112B is the notification level. When the third mode is selected and the traveling speed V2 of the tracked vehicle 202 is equal to the traveling speed V1, the notification level. In the table 112B, the fourth mode is selected as the notification level, and when the traveling speed V2 of the tracked vehicle 202 exceeds the traveling speed V1, the fifth mode is selected as the notification level in the notification level table 112B. The scene in which the fourth mode is selected is when the tracking vehicle 202 is continuously tracked at an appropriate distance. The scene in which the fifth mode is selected is when the chasing vehicle 202 is trying to escape from the police car 201 at high speed or is in a dangerous driving state.

  Subsequently, FIG. 10 is a flowchart illustrating an example of processing of the processor 111.

First, the processor 111 detects the host vehicle speed from the speed sensor 134 (step S2).
Next, the processor 111 receives information from the Doppler sensor 133 and measures the inter-vehicle distance L1 between the tracked vehicle 202 and the police car 201 (step S4).

Subsequently, the processor 111 determines whether or not a predetermined time has elapsed (step S6). When it is determined that the predetermined time has not elapsed, the processor 111 repeats the process of step S6 (No in step S6).
On the other hand, when the processor 111 determines that the predetermined time has elapsed (Yes in step S6), the processor 111 receives information from the Doppler sensor 133, and measures the inter-vehicle distance L2 between the tracked vehicle 202 and the police car 201 (step). S8).

  Subsequently, the processor 111 detects the speed of the tracked vehicle 202 that is the target vehicle (step S10). Here, the processor 111 detects the speed of the tracked vehicle 202 based on the distance L1 and the distance L2 measured in the process of step S4 and the process of step S8.

Then, based on the detected speed V2 of the tracked vehicle and the speed V1 of the police car 201, the notification level in the notification level table 112B of FIG. 9 is selected and executed (step S12).
Finally, the processor 111 determines whether the own vehicle speed of the police car 201 is 0 (step S14). When it determines with the own vehicle speed of the police car 201 not being 0 (No of step S14), it returns to the process of step S2 and repeats the process of step S2 to step S12.
On the other hand, when it determines with the own vehicle speed of the police car 201 being 0 (Yes of step S14), a process is complete | finished.

(Other examples)
FIG. 11 is a schematic diagram showing another example of the notification level table 112B of FIG.

  The notification level table 112B shown in FIG. 11 selects the notification level based on the relative distance (m) of the tracked vehicle.

As shown in FIG. 11, in another example, when the driving mode of the police car 201 is “normal security”, no particular setting is made, and the driving mode of the police car 201 is “emergency driving”. Only the settings are made.
When the travel mode is “normal security”, the state determination between the police car 201 and the tracked vehicle 202 and the setting of the notification level may be performed.

  For example, when the driving mode of the police car 201 is “emergency driving”, the state determination between the police car 201 and the tracked vehicle 202 is that the driving speed V1 of the police car 201 is “0 km / hour or more and less than 80 km / hour”. When the relative distance to the tracked vehicle 202 is 100 m or less, the notification level in the notification level table 112B is set to the first mode, and when the relative distance between the police car 201 and the tracked vehicle 202 exceeds 100 m. In the notification level table 112B, the second mode is selected as the notification level.

  Further, when the driving mode of the police car 201 is “emergency driving”, the state determination between the police car 201 and the tracked vehicle 202 is that the driving speed V1 of the police car 201 is “80 km / hour or more and less than 110 km / hour”. When the relative distance to the tracked vehicle 202 is 200 m or less, the notification level in the notification level table 112B is set to the second mode, and when the relative distance between the police car 201 and the tracked vehicle 202 exceeds 200 m. In the notification level table 112B, the third mode is selected as the notification level.

  Furthermore, the driving mode of the police car 201 is “emergency driving”, the state determination between the police car 201 and the tracked vehicle 202 is that the driving speed V1 of the police car 201 is “110 km / hour or more”, and the police car 201 and the tracked vehicle 202 In the notification level table 112B, the fourth mode is selected as the notification level, and when the relative distance between the police car 201 and the tracked vehicle 202 exceeds 300 m, the notification level table 112B In 112B, the fifth mode is selected as the notification level.

Thus, the level selection which is the process of step S12 may be performed based on the inter-vehicle distance (relative distance) L1 in the process of step S4 of FIG.
Further, another notification level table may be set according to the increase / decrease change in the inter-vehicle distance, and the level selection which is the process of step S12 may be performed.

FIG. 12 is a schematic diagram showing still another example of the notification level table 112B of FIGS. 9 and 11.

  As shown in FIG. 12, in another example, when the police car 201 is in the “stopped state” and the target vehicle approaches the police car 201 from behind, the target vehicle is alerted. To do.

  For example, in still another example, the traveling mode of the police car 201 is “stopped”, and the state determination between the police car 201 and the target vehicle is that the traveling speed V2 of the target vehicle is “0 km / hour or more and less than 80 km / hour”. In the case where the relative distance between the police car 201 and the target vehicle is 100 m or less, the notification level in the notification level table 112B is selected when the second mode is selected and the relative distance between the police car 201 and the target vehicle exceeds 100 m. In the notification level table 112B, the first mode is selected as the notification level.

  Further, in the state determination between the police car 201 and the target vehicle, when the traveling speed V2 of the target vehicle is “80 km / hour or more and less than 110 km / hour” and the relative distance between the police car 201 and the target vehicle is 200 m or less, a notification is given. In the level table 112B, the third mode is selected as the notification level, and when the relative distance between the police car 201 and the target vehicle exceeds 200 m, the second mode is selected as the notification level in the notification level table 112B.

  Further, in the state determination between the police car 201 and the target vehicle, when the traveling speed V2 of the target vehicle is “110 km / hour or more” and the relative distance between the police car 201 and the target vehicle is 300 m or less, the notification level table 112B As the notification level, the fifth mode is selected, and when the relative distance between the police car 201 and the target vehicle exceeds 300 m, the fourth mode is selected as the notification level in the notification level table 112B.

  Thus, the level selection which is the process of step S12 may be performed based on the inter-vehicle distance (relative distance) L1 in the process of step S4 of FIG.

(A)
As described above, the vehicle warning light system 100 or the police car 201 including the vehicle warning light system 100 is determined by the processor 111 as to whether the police car 201 and the tracked vehicle 202 are moving away from each other or approaching each other. Accordingly, the lighting or blinking mode of the diffused warning light 120 is changed.

In addition, since the vehicle is changed from the first mode to the fifth mode according to the speed of the police car 201, the tracked vehicle 202 can be made to recognize the presence of the police car 201. Further, the police car 201 and the tracked vehicle 202, the first vehicle is changed from the first mode to the fifth mode according to the change in the relative speed or the inter-vehicle distance and the inter-vehicle distance. Variations can be changed according to changes in the inter-vehicle distance and the inter-vehicle distance, and can be recognized safely.

  Further, when the degree of danger is high, the processor 111 emits the diffused warning light 120 to the front concentrated irradiation mode, so that the presence of the police car 201 is safely recognized by the tracked vehicle 202 according to the change in the inter-vehicle distance. And the presence of the police car 201 can be recognized around the tracked vehicle 202.
