As shown in FIG. 1, the hazard lamp control device 1 includes a navigation device (traveling road detecting means) 2 equipped with a GPS and detecting the current position of the vehicle, and a communication between the navigation device 2 and a roadside device at an entrance or exit of a toll road. And an ETC device (traveling path detecting means) 3 for automatically paying a fee, a following vehicle existing behind the own vehicle, and a following vehicle distance detecting unit (following vehicle detecting means) 4 for detecting the distance thereof. Have.
[0014]
Further, the hazard lamps 6 provided on the left and right sides of the front and rear portions of the vehicle, a combination switch 7 for operating the blinking and extinguishing of the hazard lamps 6, and the blinking of the hazard lamps are automatically operated. An automatic hazard cancel switch 5 for switching between manual operation and manual operation, based on an output signal of the navigation device 2, an output signal of the ETC device 3, an output signal of the following vehicle distance detection unit 4, and an output signal of the combination switch 7. A controller (control means) 8 for controlling the flashing and extinguishing of the hazard lamp 6. Further, the controller 8 is supplied with vehicle speed information by CAN communication or the like.
[0015]
Next, the operation of the hazard lamp control device 1 according to the present embodiment configured as described above will be described with reference to the flowchart shown in FIG. 2 and the reference diagrams shown in FIGS.
[0016]
First, it is determined whether or not the automatic hazard cancel switch 5 is turned on (step ST1). If it is turned on (ON in step ST1), the automatic operation is not performed and the process returns to step ST1.
[0017]
When the automatic hazard cancel switch 5 is off (OFF in step ST1), whether the own vehicle is traveling on a highway (within a predetermined traveling road) based on the current position information of the own vehicle output from the navigation device 2 It is determined whether it is (step ST2). If the vehicle is not traveling on a highway (NO in step ST2), the process returns to step ST1.
[0018]
On the other hand, if the vehicle is traveling on a highway (YES in step ST2), it is determined whether or not the traveling speed of the vehicle supplied by CAN communication or the like is equal to or lower than a predetermined value (first predetermined speed). Is performed (step ST3). If it exceeds the predetermined value (NO in step ST3), it is determined that the vehicle is traveling at high speed, and the hazard lamp 6 is not flashed. That is, the process returns to step ST1.
[0019]
If the value is equal to or smaller than the predetermined value (YES in step ST3), a blink command is output to the hazard lamp 6, and the left and right hazard lamps 6 are simultaneously blinked (step ST4).
[0020]
FIG. 3 is an explanatory view schematically showing the situation at this time. When the own vehicle P runs on the main line of the highway and the speed drops due to traffic congestion, the hazard lamp 6 is turned on and the following vehicle Q You will be notified that the speed has decreased.
[0021]
Even when the vehicle speed becomes equal to or lower than a certain value, based on the output information of the navigation device 2, the own vehicle is entering a parking area or a service area, or is traveling near a tollgate. In this case, the hazard lamp 6 does not blink when the vehicle is traveling near the entrance or exit of the expressway.
[0022]
That is, as shown in FIG. 4, when the host vehicle P is traveling in a deceleration lane such as a service area or a parking area, the left and right hazard lamps 6 are not blinked. This can be detected by inputting a turn left operation of the vehicle (a blinking operation of the left turn signal) from the combination switch 7 and that the vehicle speed becomes equal to or lower than a certain speed. FIG. 4 shows a state in which only the left hazard lamp 6 is blinking to change the course to the left.
[0023]
Similarly, as shown in FIG. 5, when the host vehicle P is approaching the tollgate, the hazard lamp 6 is not blinked.
[0024]
Then, after the hazard lamp 6 flashes in the process of step ST4 in FIG. 2, the following vehicle distance detection unit 4 determines whether or not the following vehicle is approaching within a predetermined distance behind the host vehicle (step ST4). If it is approaching (ST5) (YES in step ST5), the blinking of the hazard lamp 6 ends (step ST7). That is, if the own vehicle decelerates due to traffic congestion or the like and the hazard lamp 6 automatically turns on, and then the following vehicle approaches the own vehicle and is decelerated, the driver of the following vehicle already has the speed of the own vehicle. Recognizing the decrease, it is determined that the danger of the abnormal approach has been resolved, and the blinking of the hazard lamp 6 is terminated.
[0025]
When the following vehicle is not approaching within a predetermined distance behind the own vehicle (NO in step ST5), the running speed of the own vehicle supplied by the CAN communication or the like becomes constant (second predetermined speed). ) Is determined (step ST6). If the speed does not exceed the predetermined speed (NO in step ST6), the process returns to step ST5. That is, the blinking of the hazard lamp 6 is continued.
[0026]
On the other hand, when the traveling speed of the own vehicle is equal to or higher than the certain speed (YES in step ST6), it is determined that the danger of the abnormal approach of the following vehicle has been avoided, and the blinking of the hazard lamp 6 is ended ( Step ST7).
[0027]
In this manner, in the hazard lamp control device 1 according to the present embodiment, when the vehicle is running at a low speed or stopped due to traffic congestion or the like while driving on a highway, the hazard lamp 6 automatically blinks, This can be immediately notified to the following vehicle, and abnormal approach of the following vehicle to the own vehicle can be reliably avoided.
[0028]
Further, in areas where the vehicle decelerates during normal operation, such as a service area or a parking area, a toll booth, an entrance, an exit, etc., the hazard lamp 6 does not automatically blink, so that unnecessary blinking of the hazard lamp 6 is avoided. Can be.
[0029]
As described above, the hazard lamp control device 1 of the present invention has been described based on the illustrated embodiment. However, the present invention is not limited to this, and the configuration of each unit may be any configuration having the same function. Can be replaced.
[0030]

[0031]
In this embodiment, the navigation device 2 detects whether the vehicle is traveling on a highway. However, the present invention is not limited to this, and the vehicle may be detected by the ETC device 3. When it is detected that the vehicle has passed the entrance of the highway, it can be determined that the vehicle is traveling on the highway.
[0032]
In the above-described embodiment, the conditions for turning off the automatically blinking hazard lamp 6 include the conditions shown in steps ST5 and ST6 in FIG. 2, that is, when the following vehicle approaches, and when the traveling speed of the own vehicle is constant. Although a case has been described above, the present invention is not limited to this, and the hazard lamp 6 automatically blinks, and it is also possible to end the blinking when the number of blinks reaches a predetermined number. Further, it is also possible to turn off the automatically blinking hazard lamp 6 only by manual operation without automatically turning off the hazard lamp 6.
