Specifically, it does not work when driving slowly (30 km / h or less), and when driving more than 30 km / h, it prevents the traffic accident caused by overcoming the opponent's car without turning the turn signal lamp.
The conventional lane departure warning system of the Republic of Korea 10-2007-0075789 (2007.07.24) is a system in which the lane departure is displayed only to the driver himself by the LDWS (lane detector), GPS, BPF, There is a problem that can not be noticed by other cars that are operating.
A navigation device having a lane change guidance function, a lane change guidance system including the lane change guidance function, and a lane change guidance method using the lane change guidance function, which is a prior art Korean Patent Publication No. 10-2008-0084452 (2008.09.19), receives a lane change signal, , It is determined whether or not the lane change is possible by comparing the vehicle and the distance with the set condition in the rear side. However, this is a device required for the driver who performs the normal driving according to the normal road traffic law, There is a problem in that it can not be used for a driver who habitually interrupts zigzag.
The configuration of the present invention detects the speed by the GPS 16 and detects the steering angle by the steering angle sensor (13) when the steering wheel speed is exceeded, The center control unit 10 recognizes the input and stores it in advance and detects when the input value is larger than the input value by the BPF (Band Pass Filter), and outputs the left direction 18 and the right direction 18 'direction indicator light and the emergency operation 17.17' ), The lane detection algorithm of the central control unit 10 by the two lane detectors 11 (LDWS) installed in the headlight box or the front part of the vehicle, when exceeding the lane running speed The left or right lane is distinguished and the left direction 18 and the right direction 18 'direction indicator lights and the emergency operation sound are emitted for three seconds through the lane departure alarm generating section 14 so that the driver himself / herself is recognized as the emergency operation sound , The other vehicle traveling around is informed by a turn signal light, and the LDWS (lane detector) The lane detection algorithm of the control unit 10 does not work on the road surface display (U-turn zone display, crosswalk notice display, crosswalk stop line, pedestrian crossing, lane change line, etc.) (15). When switching to the automatic mode, it is judged that there is no operation by the switch by manual operation, and when the direction indicator is manually operated, the operation sound sensor Direction indicators are used as a substitute for existing vehicles.
The recognition method of the road surface indication and the lane detection algorithm and the like can be implemented by the method described in the above-mentioned [Prior Art Document], the method described in "Lane recognition using lane and road surface information ". That is, a method of inputting various types of patterns of the road surface display using the template matching technique to recognize the road surface display, and comparing and analyzing them may be applied, and the driving vehicle recognition can be performed through its application.

Take an example of application of the present invention.
