And a direction determining step (step S402) of determining a traveling direction of the vehicle 200 traveling on the one-way street 300 based on the detection result of each sensor unit; And an alarm step (step S403) of outputting a primary alarm or a secondary alarm according to the determined state of the vehicle 200 in the driving direction.

In more detail, first, whether the vehicle 200 proceeds through the one-way street 300 is provided through the first sensor unit 110 installed at the rear of the one-way street 300 and the second sensor unit 120 installed at the beginning. Detect (step S401).

When the first sensor unit 110 and the second sensor unit 120 detects whether the vehicle 200 is in progress, according to the detection order of the pair of infrared light sensors A and B 112 to 124 constituting each sensor unit. The driving direction of the vehicle 200 is determined (step S402).

As shown in FIG. 3, the infrared light sensors B (114, 124) installed at the rear side with respect to the traveling direction of the one-way street 300 first detect the driving of the vehicle 200, and then the infrared light sensors A (112, 122) installed at the front. Detects the driving of the vehicle 200 (a), it determines that the driving is forward.

In addition, if the infrared light sensor A (112, 122) installed in front of the vehicle 200 first detects the travel of the vehicle 200, then the infrared light sensor B (114, 124) installed in the rear senses the driving of the vehicle 200 (b), the reverse driving Judging by.

As a result of the determination, when it is determined that the detection result of any one of the first sensor unit 110 and the second sensor unit 120 is the reverse driving of the vehicle 200, the first alarm is output, and the first sensor unit 110 and the first sensor unit 110 are output. When the detection result of the second sensor unit 120 continuously determines that the vehicle 200 is driven in reverse, a secondary alarm is output (step S403).

At this time, the primary alarm is, for example, the character output through the LED display unit 140, the secondary alarm is, for example, the alarm sound and flashing of the warning light 150 together with the character output through the LED display unit 140 at the same time. Is output.

On the other hand, the state of the driving direction of the vehicle 200 is switched according to the detection result of each sensor unit and the alarm method according to this will be described in more detail with reference to FIG.

FIG. 5 is a state diagram illustrating a vehicle reverse driving prevention warning method according to an exemplary embodiment of the present invention.

As shown in FIG. 5, the state according to the driving direction of the vehicle 200 is a standby state (state S1) in which the reverse driving of the vehicle 200 is not detected, and the reverse driving of the vehicle 200 is performed by the first sensor unit 110. Primary reverse detection-secondary non-sensing state (state S2) detected by the) and the reverse driving of the vehicle 200 is detected by the second sensor unit 120 primary non-detection-secondary reverse detection state (state S3) and In addition, the reverse driving of the vehicle 200 includes a primary reverse detection-second reverse detection state (state S4) continuously detected by the first sensor unit 110 and the second sensor unit 120.

First, when the first reverse driving is sensed by the first sensor unit 110 in the standby state (state S1) in which no reverse driving of the vehicle 200 is detected at all (a), for example, the vehicle 200 is one-sided. When driving back to the passageway 300, the state transition to the state S2 and the first alarm is performed.

At this time, when the second reverse driving is sensed by the second sensor unit 120 (e), for example, when the vehicle 200 enters the forward driving in the one-way street 300 and enters the reverse driving, the vehicle switches to the state S3. Primary alarm is performed.

In addition, for example, the state S1 is maintained when the entry of the vehicle 200 is not detected or when the driving is detected.

When the reverse driving of the vehicle 200 is detected only in the first sensor unit 110 and in the state S2 during the primary warning, when the forward driving of the vehicle 200 is detected by the first sensor unit 110 (b), for example, For example, when the vehicle 200 reverses driving to the one-way street 300 and enters a U-turn after driving, the primary alarm is released and the state S1 is switched.

In this case, when the second reverse driving is detected by the second sensor unit 120 (c), for example, when the vehicle 200 enters the reverse driving to the one-way street 300 and proceeds continuously, the secondary alarm is performed. At the same time it is switched to state S4.

In addition, for example, the vehicle 200 continuously performs the first alarm until the vehicle 200 enters the one-way street in reverse driving and stops or until the second reverse driving is detected by the second sensor unit 120. S2 is maintained.

When the reverse driving of the vehicle 200 is detected only in the second sensor unit 120 and in the state S3 during the first alarm, when the forward driving of the vehicle 200 is detected by the second sensor unit 120 or a predetermined time elapses ( f) For example, when the vehicle 200 completely exits the one-way street 300 or another vehicle enters the normal driving, the primary alarm is released and the state S1 is switched.

At this time, when the first reverse driving is sensed by the first sensor unit 110 (g), for example, the vehicle 200 is completely deviated from the one-way street 300 by the reverse driving and at the same time, the other vehicle 200 is one-way. When entering the reverse driving to 300, the state is switched to the state S2 while continuing to perform the primary alarm.

In addition, for example, if a predetermined time has not elapsed, state 3 is maintained while continuously executing the primary alarm.

In the state S4 where the reverse traveling of the vehicle 200 is continuously detected by the first sensor unit 110 and the second sensor unit 120 and is in the secondary warning state, the first sensor unit 110 and the second sensor unit 120 are connected to the first sensor unit 110 and the second sensor unit 120. When the forward driving of the vehicle 200 is detected or a predetermined time elapses (d), for example, the vehicle 200 entered into the reverse driving completely leaves the one-way street 300 or other vehicles enter the forward driving. When the secondary alarm is released, the state is switched to the state S1 at the same time.

In addition, for example, when the reverse driving of another vehicle 200 is detected by the first sensor unit 110, the state 4 is maintained while continuously performing the secondary alarm.

In this way, it is possible to detect the reverse driving of the vehicle and to perform an alarm for two times according to various driving conditions of the vehicle to alert the driver and prevent an accident in advance.
