Therefore, definitions of these terms should be made based on the contents throughout this specification.
1 is a block diagram showing an apparatus for access warning of a vehicle according to an embodiment of the present invention, Figure 2 is an exemplary view showing an installation state of an access warning apparatus for a vehicle according to an embodiment of the present invention, Figure 3 Is a cross-sectional view of the speed bumps showing the installation state of the light emitting means of the vehicle warning device according to an embodiment of the present invention.
As shown in FIG. 1, an apparatus for warning a vehicle according to an exemplary embodiment of the present invention includes a vehicle detecting unit 10, a vehicle speed measuring unit 20, a control unit 30, a light emitting unit 40, and a power supply unit 50. ).
The vehicle detecting unit 10 detects a vehicle approaching the speed bumps 70 at a position where the vehicle warning device is installed.
The vehicle speed measuring unit 20 measures the speed of the approaching vehicle.
As described above, the vehicle detecting unit 10 and the vehicle speed measuring unit 20 are provided with a pillar 60 on the side of the road so as to be adjacent to the speed bumps 70 as shown in FIG. 2 and the infrared camera 15 on the pillar 60. You can install it to detect the approaching vehicle or to measure the speed of the vehicle.
The light emitting means 40 is well visible to the vehicle approaching from the front by installing a hole (75) embedded in the speed bumps (70) to the ground in the direction of entry of the vehicle in the direction of entry of the vehicle and then embedded the LED 42 Be alerted.
The controller 30 receives the output values of the vehicle detecting unit 10 and the vehicle speed measuring unit 20 and controls the light emitting means 40 according to the speed of the vehicle when the vehicle approaches.
That is, when the vehicle approaches, the light emitting means 40 is turned on. When the speed of the vehicle is fast, the flashing speed of the light emitting means 40 is increased.
In addition, the controller 30 allows the light emitting means 40 to flow while the flashing state swings according to the speed of the vehicle so that the driver can know the approaching danger of the approaching vehicle to prevent overspeed.
5 is an exemplary view installed at an intersection to explain a control method of a vehicle warning device according to another embodiment of the present invention, Figure 7 is a control method of a vehicle warning device according to another embodiment of the present invention. It is an exemplary figure which shows the light emission state by.
When the vehicle approach warning device is installed in each lane of the intersection as shown in FIG. 5, when the vehicle approaches the lane, the controller 30 turns on the light emitting means 40 of the lane and measures the approaching speed of the vehicle. By controlling the flashing speed or the swing speed of the light emitting means 40 of the lane, the vehicle running in the adjacent lane can predict the approaching risk of the approaching vehicle to prevent the overspeed.
At this time, when the light emitting means 40 is divided into the corresponding lane and the adjacent lane as shown in FIG. Intuitive judgment will help prevent overspeed.
On the other hand, the power supply unit 50 supplies power to the entire vehicle access warning device through the control unit 30.

By using the piezoelectric storage battery 54 that stores the pressure energy passed by the vehicle using electricity or a mixture thereof, the warning device can be operated by self-generation without receiving power from the outside.
4 is a flowchart illustrating a control method of an apparatus for access warning of a vehicle according to an exemplary embodiment of the present invention.
As shown in FIG. 4, the control method of the vehicle's approach warning apparatus according to an exemplary embodiment of the present invention first detects a vehicle approaching through the vehicle detecting unit 10 in a corresponding lane in which the vehicle's approach warning apparatus is installed ( S42).
At this time, when the vehicle is detected, the controller 30 turns on the light emitting means 40 to warn the approaching vehicle of the speed bumps 70 so as to prevent overspeed (S44).
When the vehicle is detected as described above, the light emitting means 40 is turned on to minimize the power consumption.
After the light emitting means 40 is turned on, the speed of the vehicle approaching through the vehicle speed measuring unit 20 is measured (S46).
When the approach speed is high according to the measured approach speed of the vehicle, the flashing speed of the light emitting means 40 is displayed to increase the approach risk, and when the approach speed is slow, the blink rate is slowed to lower the approach risk. It is displayed (S48).
At this time, depending on the speed of the vehicle, the light emitting means 40 may be displayed to flow while the flashing state swings.
6 is a flowchart illustrating a control method of an apparatus for access warning of a vehicle according to another exemplary embodiment of the present disclosure.
In the case of the control method of the vehicle according to another embodiment of the present invention shown in Figure 6, the approach warning device of the vehicle as shown in Figure 5 is installed in each lane of the intersection to drive the vehicle approaching the adjacent lanes Be aware of the risk of access.
First, a vehicle 80 approaching through the vehicle detecting unit 10 is detected by an approach warning device of a vehicle installed in each lane (S62).
When the vehicle 80 is detected through the vehicle detection unit 10, the light emitting means 40 of the corresponding lane detected by the vehicle detection unit 10 is turned on (S64).
Thereafter, the vehicle speed measuring unit 20 measures the approach speed of each vehicle 80 (S66).
The light emitting means 40 of the adjacent lanes blinks at the approach speed of the vehicle 80 thus measured (S68).
That is, the light emitting means 40 installed in lane B blinks by the approach speed of the vehicle 80 measured in lane A. At this time, when the vehicle 80 is not detected in lane B, the light emitting means 40 is not turned on, and thus no flicker occurs. However, when the vehicle 80 is detected in the lane B and the light emitting means 40 is turned on, the light emitting means 40 blinks according to the approach speed of the vehicle 80 measured in the lane A to pass through the intersection. When the approaching danger corresponding to the speed of the vehicle 80 approaching the intersection in the adjacent lane is displayed.
In this case, when the light emitting means 40 installed on the speed bumps 70 is divided into right and left sides as shown in FIG. By blinking in accordance with the approaching speed of the approaching vehicle 80 to grasp the speed of the approaching vehicle 80 and the approaching vehicle 80 at the intersection to prevent overspeed when passing through the intersection.
