Vehicle approach notification device and method therefor

A vehicle approach notification device, comprising:

• a camera configured to capture an image around a vehicle;
• a sensor module configured to collect environmental data around the vehicle;
• a lamp configured to operate depending on an on/off manipulator;
• and
• at least one processor electrically connected with the camera, the sensor module, and the lamp, wherein the at least one processor is configured to:
• detect an obstacle being present in a direction of travel of the vehicle using the camera and the sensor module,
• analyze an angle of the obstacle, the angle corresponding to an angle formed by a reference axis corresponding to the direction of travel of the vehicle and a first straight line, and an amount of protrusion of the obstacle with respect to a front end or a rear end of the vehicle,
• determine a vehicle entry notification display area based on the angle of the obstacle and the amount of protrusion of the obstacle, and
• output a notification to be displayed on the vehicle entry notification display area, by the lamp,
• wherein the first straight line is a straight line connecting a center of a front end or a rear end of the vehicle with an outermost point of the obstacle, and
• wherein the at least one processor is further configured to:
• continuously update the amount of protrusion of the obstacle, and
• update the vehicle entry notification display area depending on the amount of updated protrusion of the obstacle;
• identify whether communication is connected with a moving object,
• when the communication is not connected, output the notification on the vehicle entry notification display area, and
• when the communication is connected:
• determine an approach direction and a distance of the moving object with respect to the vehicle, and
• dynamically control the vehicle entry notification display area based on the approach direction and the distance.
