Description

{APPARATUS AND METHOD FOR AUTOMATICALLY DETECTING UNLIT DIRECTION INDICATORS}

The present invention relates to an apparatus and method for automatically detecting a vehicle with a turn signal not illuminated. More specifically, the present invention relates to a vehicle (two-wheeled vehicle) located in front/side of the vehicle changing lanes with the turn signal not illuminated. It relates to a device and method for automatically detecting that a situation is occurring.

Turning on the turn signal when changing directions is a driver's duty specified in the Road Traffic Act. According to Article 38 of the Road Traffic Act, the driver of any vehicle must turn left, turn right, cross, U-turn, slow down, stop or reverse, or change course while proceeding in the same direction, or enter or exit a roundabout. You must signal with your hand, direction indicator, or light until the action is completed. However, there are many vehicles that change lanes without turning on the turn signal, and according to the Road Traffic Authority, 48% of retaliatory driving and 43% of reckless driving are calculated to be caused by not turning on the turn signal. In other words, non-use of turn signals can cause collisions and have a high risk of retaliatory driving.

The present invention was proposed to solve the above-described problems, and is an automatic detection device and method for non-illuminated turn signal lights that can prevent collision accidents caused by surrounding vehicles (including two-wheeled vehicles) changing lanes without turning on the turn signal lights while driving. The purpose is to provide.

The automatic detection device for the absence of turn signal lights according to the present invention includes a sensor unit that acquires information on the presence or absence of vehicles around the vehicle and changes in behavior, a judgment unit that determines whether the turn signal lights of vehicles around the vehicle are operating using the collected information, and a device that determines whether the turn signal lights of vehicles around the vehicle are operating. It includes a control unit that records data when a nearby vehicle changes lanes without turning on its turn signal.

The sensor unit acquires information on the presence or absence of vehicles around the vehicle and change in behavior using an external environmental sensor, based on precise road map information and location information of the vehicle.

The sensor unit includes a camera, radar, and lidar, and the radar is a wide-angle SRR (Short Range Radar) greater than a preset angle.

The determination unit determines whether a vehicle surrounding the own vehicle enters the driving lane of the own vehicle and whether the turn signal lamp is activated.

The determination unit determines whether a vehicle surrounding the own vehicle deviates from the driving lane of the own vehicle and whether a turn signal lamp is activated.

The determination unit uses the relative distance and relative speed to calculate expected collision time information between the vehicle and the vehicle surrounding the own vehicle, and when the expected collision time information is within a preset time in a situation where the own vehicle does not change lanes, It is judged that there is a risk of collision.

The control unit records and stores the data including the location of the vehicle, the license plate number of the front or side vehicle, and the front or side image.

The method for automatically detecting a turn signal not turned on according to the present invention includes (a) collecting precise road map information, location information of the own vehicle, and information on surrounding vehicles, (b) information on turn signal lights of vehicles around the own vehicle, and information on lane change situations. a step of collecting, (c) a step of determining a violative vehicle that enters the driving lane of the own vehicle or deviates from the driving lane of the own vehicle without turning on the turn signal, and (d) a step of recording and storing information about the violating vehicle. Includes.

In step (a), information on the surrounding vehicles is collected using a camera, radar, and lidar, and the radar is a wide-angle SRR (Short Range Radar) greater than a preset angle.

Step (b) calculates the expected collision time information between the own vehicle and the surrounding vehicle due to a lane change of the surrounding vehicle in a situation where the own vehicle does not change lane, and step (c) calculates the expected collision time information. As a result, if it is determined that there is a risk of collision, the surrounding vehicle is judged to be a violation vehicle.

According to the present invention, the effect of creating a safe road environment and cultivating the law-abiding spirit of drivers is to automatically detect a vehicle that changes lanes while driving with the turn signal not turned on and provide a warning informing the vehicle of the risk of an accident. there is.

According to the present invention, a warning is provided to vehicles that change lanes with the turn signal not turned on while driving, thereby reducing the number of cases of changing lanes with the turn signal not turned on, resulting in retaliatory driving caused by the turn signal not being turned on. Or, it is possible to prevent reckless driving.

Figure 1 shows an automatic detection device for a turn signal lamp not turned on according to an embodiment of the present invention.

The automatic detection device for the absence of turn signal lights according to an embodiment of the present invention includes a sensor unit 110 that acquires information on the presence or absence of vehicles around the own vehicle and information on changes in behavior, and uses the collected information to determine whether the turn signal lights of vehicles around the own vehicle are operating. It includes a determination unit 120 that makes a decision and a control unit 130 that records data when a vehicle around the vehicle does not turn on its turn signal and changes lanes.

The sensor unit 110 uses external environmental sensors (cameras, radars, lidar, etc.) based on precise road map information and location information of the own vehicle to obtain information on the presence or absence of vehicles (including two-wheeled vehicles) and changes in behavior around the vehicle. do. The radar utilizes SRR (Short Range Radar) with a wide angle (e.g. 150 degrees).

The determination unit 120 uses the collected information to determine whether a vehicle surrounding the vehicle enters the vehicle's driving lane and whether the turn signal lamp is activated. Figure 2 shows a situation in which the determination unit calculates the expected collision time according to an embodiment of the present invention. The determination unit 120 calculates the expected time to collision (TTC) using the relative distance (d _rel ) and relative speed (v _rel ), as shown in Equation 1.

In the case where there is no lane change of the own vehicle, if the calculated expected collision time is less than the standard value (e.g., 1 second), the determination unit 120 determines that there is a risk of collision.

The determination unit 120 according to an embodiment of the present invention determines whether the vehicle ahead or the vehicle to the side changes lanes based on the following criteria. In the case of the vehicle in front, if it suddenly disappears (deviates) from a driving situation where it was following the vehicle in front, such as at an intersection or turning section, it is judged to have changed lanes. In the case of a vehicle on the side, it is determined whether it is entering the own vehicle's driving lane from the left or right, and when the lane is obscured by surrounding vehicles while recognizing the driving lane with a camera, it enters through object recognition within a certain range based on the own vehicle's driving lane. Determine whether or not In addition, using radar and lidar information (distance recognition or object recognition), it is determined that the vehicle has changed lanes when it enters the own vehicle's driving lane within a certain range.

According to an embodiment of the present invention, the determination unit 120 detects a vehicle changing lanes from the lane on either side of the own vehicle's lane to the own vehicle's lane with the turn signal not illuminated, and a vehicle with the turn signal not illuminated in the lane on both sides of the own vehicle's lane. Any vehicle that changes lanes in this condition can be judged as a violation vehicle.

According to another embodiment of the present invention, the determination unit 120 may determine that another vehicle that turns on the turn signal and changed lanes but did not follow the correct method of using the turn signal is a caution vehicle. In this case, the control unit 130 transmits information related to the cautioned vehicle to the control center, and the control center provides guide information on how to properly use the turn signal to the owner of the cautioned vehicle. According to the Enforcement Decree of the Road Traffic Act, when turning left, crossing, U-turning, or changing course to the left lane, or turning right or changing course to the right lane, the turn signal light is turned on from 30 meters (100 meters in the case of highways) before the point of action until the action is completed. It is stipulated to do so. According to regulations, on general roads, turn signals must be activated for at least 3 seconds at a distance of 30 meters, and the appropriate number of flashes is 4-5 times. On highways, turn signals must be activated for at least 5 seconds at a distance of 100 meters. The appropriate number of flashes should be 7-8 times. If a vehicle around your vehicle changes lanes into your own lane with the turn signal on, but suddenly changes lanes and activates the turn signal only once, the vehicle in question (the turn signal is not on, but turns in the correct way) Vehicles that do not use indicator lights) are judged to be caution vehicles. In other words, as mentioned above, a vehicle with a risk of collision is judged as a violator based on the TTC. Although there is no risk of a collision based on the TTC (e.g., suddenly changing lanes into the free space in front of the own vehicle that is stopped on a congested road) (in the case of other vehicles coming in, etc.), the vehicle is determined to be a caution vehicle and a warning is provided, and in case of violation of driving regulations in congested areas, follow-up procedures are carried out to issue a warning to the driver and issue a fine.

If a vehicle around the vehicle changes lanes without turning on the turn signal, or if it is determined that there is a risk of collision as a result of the determination unit 120's calculation of the expected collision time, the control unit 130 operates at a certain point before the expected collision time ( Example: Data is recorded and stored from (t-3 seconds ago), and the data includes the own vehicle location, front/side vehicle number, and front/side images.

The control unit 130 transmits information about vehicles that have changed lanes with the turn signal not on to the control center, and the control center uses CCTV, etc. to provide a warning or issue a fine to the driver according to the results of the search for the same vehicle. .

Figure 3 shows a method for automatically detecting a turn signal lamp not turned on according to an embodiment of the present invention.

In step S301, precise road map information (intersections, straight lines, turning sections), location information of the own vehicle, and information on vehicles around the own vehicle (front and side vehicles) are collected. In step S301, information on vehicles (including two-wheeled vehicles) around the vehicle is collected using external environmental sensors (cameras, radars, lidar, etc.), and the radar uses a wide-angle (e.g. 150 degree) SRR (Short Range Radar). It is desirable to utilize it.

In step S302, the presence or absence of the vehicle in front is determined, and if present, in step S303, information on the turn signal of the vehicle in front is collected.

In step S302, the presence or absence of a vehicle ahead is determined. If not, the presence or absence of a vehicle on the side is determined in step S304. If present, step S304 collects information on the turn signal of the vehicle on the side.

In step S306, it is checked whether the vehicle in front or the vehicle on the side changes lanes without the turn signal lamp on and violates the lane change regulations. If so, the data is recorded and stored in step S307. In step S306, the expected time to collision (TTC, Time to Collision) is calculated using the relative distance (d _rel ) and relative speed (v _rel ), and if the calculated expected time to collision is less than the reference value (e.g. 1 second) , it can be determined that there is a risk of collision, and a vehicle that changes lanes with the turn signal not on or changes lanes with a risk of collision is judged to be a vehicle that violates lane change regulations.

Step S308 provides a warning to the driver of the vehicle in question and issues a fine.
