Embodiment Construction

[0026] First refer to figure 1 , for illustrative purposes, shows an automatic vehicle exterior light control system 5 to be installed in a controlled vehicle 10 . While the control system 5 is depicted with the interior mirror assembly as a whole, it should be understood that the control system or any of its individual components may be mounted in any suitable location within or on the controlled vehicle 10 . The term "controlled vehicle" is used herein to denote a vehicle that includes an automatic vehicle exterior light control system. An appropriate location for mounting the associated image sensor is one that provides an unobstructed view generally in front of the controlled vehicle 10 and allows the headlights of the approaching vehicle 20 to be detected within the corresponding glare zone 25 of the controlled vehicle. 21 and the tail lights of the preceding vehicle 15.

The present invention relates to a vehicle light control system (250) configured to distinguish between reflections off of a highly reflective surface and reflections off of atmospheric conditions of interest.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 60 / 448,793, filed February 21, 2003, pursuant to 35 U.S.C. § 119(e) (35 U.S.C § 119(e)). The disclosure of this provisional patent application is hereby incorporated by reference. Background technique [0003] To adapt to changes in traffic conditions, automatic automotive exterior light control systems provide drivers with great convenience by relieving the burden of manual switching between high-beam and low-beam headlights. As we all know, drivers are generally not suitable for using high-intensity headlights on a regular basis. Compared with low-beam headlights, high-beam headlights can provide 2 to 4 times, or more times, the visibility distance at night. Thus, enabling the driver of the controlled car to see obstacles or pedestrians earlier at night than in the opposite case. The automation of photometric switching tasks and the increased use ...
