Description

Server and vehicle for generating driving-related information based on vehicle position The present invention relates to a server and a vehicle that generate driving-related information based on the vehicle's location, and more specifically, to a technology that generates driving-related information related to the vehicle's location based on precise map information. Recently, the automotive industry has been developing various Advanced Driver Assistance Systems (ADAS) to enhance driver safety and improve driving convenience. In particular, Lane Keeping Assist Systems (LKAS) and Lane Departure Warning Systems (LDWS) play a crucial role in improving driving safety by assisting drivers in staying within their lanes. Most of these systems utilize cameras or sensors mounted on the vehicle to recognize lanes while driving; if the vehicle deviates from the lane, they warn the driver or automatically assist with steering to maintain the lane. However, existing camera and sensor-based systems have limitations due to their vulnerability to changes in the external environment. For example, during inclement weather or nighttime driving, it is difficult for cameras or sensors to clearly recognize lane lines when lighting is low or obstacles such as rain are present. In such cases, not only is the driver's visibility degraded, but the recognition capabilities of the assistance system are also compromised, which can lead to instability in lane-keeping functions. Therefore, there is a growing need for a system capable of performing stable lane recognition and driving path maintenance functions even in such environments. Furthermore, the performance of lane recognition devices may be more limited in road environments where lane markings have been erased or are not clearly marked. As a result, there is an increasing demand for more precise and stable lane keeping systems capable of supporting safe driving in such road environments. Meanwhile, technology that provides more accurate driving-related information by utilizing various in-vehicle location information systems, such as the Global Positioning System (GPS), has recently been gaining attention. Location-based information like GPS can verify not only the vehicle's position but also whether the vehicle has deviated from the driving path, offering the potential to assist the driver even in situations where lane recognition is difficult. There is a growing demand to integrate technologies that support more accurate lane keeping and route guidance using these location information systems into ADAS, thereby enabling safe and smooth driving in various road environments in the future.
