Description

Apparatus and method for outputting warning lights to other vehicles based on the risk of collision with the vehicle The present invention relates to a device and method for outputting a warning notification light to another vehicle based on the risk of collision with a vehicle, and more specifically, to a device and method capable of outputting a warning notification light to another vehicle by controlling the brightness of the light when there is a high probability of collision with another vehicle approaching from the rear or side of a moving vehicle. The automotive industry prioritizes safety, and various technologies are being developed specifically to prevent collisions between vehicles. Over the past few years, vehicle collision avoidance systems have advanced significantly alongside the development of autonomous driving technology, with various sensor technologies establishing themselves as key components of these systems. Modern vehicles primarily utilize various types of sensors, such as radar, lidar, cameras, and ultrasonic sensors, to perceive and analyze their surroundings. These sensors operate differently and play a crucial role in detecting objects around the vehicle and measuring their distance and speed. For example, radar is effective at detecting obstacles in front of the vehicle or the speed of other vehicles, while cameras are used to recognize road signs, traffic lights, and pedestrians. Furthermore, safety while driving is a critical factor, and the risk of collisions increases, particularly in complex traffic situations such as urban environments or highways. Current vehicles utilize various sensors and cameras to detect their surroundings, and these technologies are designed to enhance safety inside the vehicle. However, these systems generally focus on protecting vehicle occupants, and warning systems for other vehicles or pedestrians are often relatively inadequate. Meanwhile, the possibility of collisions with vehicles approaching from the rear and sides is particularly dangerous, which can threaten the safety of not only the vehicle occupants but also surrounding pedestrians and other drivers. Current technologies are not sufficiently effective in delivering timely warnings to other vehicles in these specific situations.
