Description

Right turn safety system and method for vehicle}

One embodiment of the present invention relates to a system and method for ensuring vehicle right-turn safety.

In general, Korea's current traffic light system is implemented as a system that indicates whether going straight or turning left is permitted. Therefore, at most intersections, traffic lights for right-turning vehicles are not installed, and some of those installed are installed as yellow flashing lights or simply operate in the opposite way to pedestrian traffic lights, so there is a problem in that it is impossible to prepare for signals that suddenly change without prior notice. .

In addition, when a traffic island for pedestrians is installed in the right turn direction, there are usually no pedestrian signals between the traffic island and the sidewalk, so vehicles turning right on the road between the sidewalk and the traffic island cannot know when pedestrians will walk between the sidewalk and the traffic island. Since there is no such thing, more caution is needed.

Accordingly, in the past three years, one in ten traffic accident pedestrian casualties is caused by a right-turning vehicle. For example, an accident may occur when a vehicle driver turns right without checking for pedestrians on the crosswalk located on the right turn path and does not reduce speed, or the driver of a high-body vehicle such as a truck causes children or children on the right turn path. Accidents are occurring due to failure to identify elderly people.

Figure 3 is a flowchart of a method for ensuring vehicle right-turn safety according to an embodiment.

Referring to Figure 3, the location data generator detects location information of the vehicle, and the object detector detects object information outside the vehicle. At this time, the object information may include at least one of a lane in the vehicle's direction of travel, a road curb located on the side of the vehicle's direction of travel, and an arrow drawn on the roadway in the vehicle's direction (S301).

Next, the control unit predicts the vehicle's right turn intention using location information and object information. Using location information, the control unit can predict that the vehicle will turn right when the vehicle's navigation guidance information guides a right turn. In addition, the control unit can additionally predict that the vehicle will turn right if the lane in the vehicle's direction is an edge lane, a road curb is located on the right side of the vehicle's direction of travel, and an arrow allowing right turns is engraved on the roadway in the vehicle's direction of travel ( S302).

Next, the control unit generates right turn path information by detecting at least one of a crosswalk, traffic light, and pedestrian in the vehicle's predicted right turn path. At this time, the right turn route information may include information on whether a crosswalk is detected, whether a pedestrian is detected, and whether a traffic light is detected (S303).

Next, the control unit outputs a vehicle control signal that controls at least one of the lamp, AVN, braking device, and HUD provided in the vehicle according to the right turn path information. The control unit can visually output vehicle approach signals or traffic light information using lamps. Alternatively, the control unit can audibly output warning sounds, warning comments, etc. using AVN. Alternatively, the control unit may visually output a warning signal using the HUD (S304).

Hereinafter, detailed operations of the control unit will be described through FIGS. 4 to 6 depending on the type and situation of the object detected on the right turn path of the vehicle.

Figure 4 is a flowchart of the operation of the control unit according to the embodiment.

The control unit outputs a jaywalking warning signal using at least one of a lamp, AVN, and HUD when no object is detected on the right turn route information or when a crosswalk is detected. For example, the control unit may use a lamp to emit a lamp signal in front of the vehicle indicating that the vehicle is entering a right turn path. Alternatively, the control unit may use AVN to output an auditory caution signal to the outside of the vehicle notifying that the vehicle is entering a right turn path. Alternatively, the control unit may use the HUD to display a visual signal indicating that the vehicle is entering a right turn path on the display area of the HUD device (S401 to 402).

That is, in the embodiment, when no object is detected on the right turn path or only a crosswalk is detected, the control unit sends a preliminary warning signal visually/audibly to the outside and inside the vehicle to notify that the vehicle is entering the right turn path. By outputting it as a warning, it can provide warning to undetected pedestrians and drivers.

Figure 5 is a flowchart of the operation of the control unit according to another embodiment.

When a pedestrian is detected on the right turn route information, the communication unit performs data communication with the pedestrian terminal (S501).

Next, the control unit transmits vehicle access information to the pedestrian terminal. The control unit can provide a warning signal or a vibration signal to the pedestrian terminal and simultaneously transmit a pop-up message to warn pedestrians crossing with their eyes fixed on the terminal (S502).

Next, the control unit can output an automatic braking signal to the vehicle's brake device. That is, the control unit can provide an environment in which pedestrians can safely cross by automatically operating the vehicle's brake system when a pedestrian is detected on the right turn route information (S503).

Figure 6 is a flowchart of the operation of the control unit according to another embodiment.

The communication unit performs data communication with the transportation infrastructure system when a traffic light is detected on the right turn route information. The communication unit can collect various traffic information including information on the lighting of traffic lights located on the right turn path from the traffic infrastructure system (S601).

Next, the control unit controls at least one of the lamp, AVN, and HUD in conjunction with the traffic light control information received from the traffic infrastructure system. The control unit may use a lamp to emit a lamp signal identical to traffic light control information (e.g., traffic light color information, remaining time information, etc.) to the front of the vehicle. Alternatively, the controller may use AVN to output an auditory signal identical to the traffic light control information to the outside of the vehicle. Alternatively, the control unit may use the HUD to display information on the status of traffic lights on the display area of the HUD device (S602).

Next, if the traffic light signal is green, the control unit outputs a vehicle stop signal using at least one of AVN and HUD. For example, the control unit can use AVN to output an auditory signal inside the vehicle requesting the vehicle to stop. Alternatively, the control unit may use the HUD to display a visual signal requesting the vehicle to stop on the display area of the HUD device (S603-604).

Next, the control unit outputs an automatic braking signal if the vehicle is not completely stopped. That is, when the traffic light signal located on the right turn path is green, the control unit outputs an initial vehicle stop signal to the driver regardless of whether or not a pedestrian is detected, and can automatically drive the vehicle's brake device if the vehicle does not come to a complete stop. Through this, when the traffic light on the vehicle's right turn path is green, the vehicle can be controlled to stop regardless of whether or not a pedestrian is detected (S605-606).
