Advanced driver assistance system for detecting and managing glare
The patent US12043252B2 describes an advanced driver assistance system (ADAS) designed to enhance vehicle safety by detecting and mitigating indirect glare conditions that may affect a driver's visibility. The system includes a light intensity detection mechanism located within the vehicle cabin, which identifies changes in light density near the driver's face, indicative of indirect glare caused by external surfaces. Additionally, the ADAS integrates a vehicle-to-everything (V2X) communication system for interaction with other vehicles and a global navigation satellite system (GNSS) to ascertain the vehicle's location. The controller within the system processes the detected glare conditions, identifies the source structure using GNSS data and a maps database, and shares this information with nearby vehicles. If a second vehicle reports an excessive glare condition, the system annotates a glare area on a map and assesses the likelihood of future glare conditions based on various parameters, including the vehicle's expected route and environmental factors.
In response to potential future glare conditions, the ADAS can notify the driver or, if necessary, partially take over vehicle control to ensure safety. This takeover may involve functions such as lane centering or adaptive cruise control, particularly if the driver does not respond to the notification. The system's design emphasizes proactive safety measures by not only detecting current glare conditions but also predicting and preparing for future occurrences, thereby enhancing the overall driving experience and reducing the risk of accidents related to visibility issues caused by indirect glare.
