Application: Vehicle lamp system, foreign substance determination device, and foreign substance determination method (Patent ID: US20240101073A1)

The patent filed by Koito Manufacturing Co Ltd. describes a vehicle lamp system that includes a vehicle lamp emitting light to the front area of a vehicle, an imaging device capturing the front area, and a foreign substance determination device. This device stores a reference light distribution pattern when no foreign substance is present on the light emitting surface and compares it with patterns captured by the imaging device to determine the presence of foreign substances. The system can detect foreign substances on the light emitting surface and take appropriate actions based on the determination result, such as activating a cleaner to clean the surface or notifying the vehicle's passengers.

Additionally, the patent includes claims detailing the configuration of the vehicle lamp system, including the use of multiple lamps, a camera accommodated within the lamp housing, and the ability to independently switch the lamps on and off for comparison. The system also involves a cleaning controller to control the cleaner based on the determination result and a notification controller to inform passengers of any foreign substances detected. The method outlined in the patent involves comparing light distribution patterns captured by the camera with a reference pattern to determine the presence of foreign substances on the light emitting surface. Overall, the patent aims to provide a system and method for effectively detecting and addressing foreign substances on vehicle lamp surfaces to ensure optimal performance and safety.
