    摘要： A system apparatus, means and method for controlling a plurality of variable reflectance mirrors (or mirror segments), including a rearview mirror and side view mirrors, which change their reflectance level in response to a plurality of drive voltages applied thereto, for controlling the vehicle lighting system and for monitoring a vehicle interior for an automotive vehicle. The system includes a light sensing device and a control circuit formed as a single VLSI CMOS circuit. The light sensing device comprises a photosensor array having a field of view encompassing a vehicle interior. The logic and control circuit determines a background light signal from photosensor element signals generated by the photosensor elements in the photosensor array indicative of light levels incident on the photosensor elements. The circuit also determines a peak light signal in three different zones or sub-arrays of the photosensor array. The zones or sub-arrays may correspond to three mirrors or mirror segments. The peak light signals in each of the zones and a common background light signal are used to determine independent and separate control signals, which are then output to separate mirror drive circuits for independently controlling the reflectance level of the rearview mirror and the left and right side view mirrors, or alternatively the segments of a mirror. The logic and control circuit uses the background light signal to control the vehicle lighting system. The logic and control circuit also determines a vehicle intrusion condition if there is movement within the vehicle in a vehicle intrusion detection mode of the vehicle interior monitoring system. The logic and control circuit also stores image data in memory in the compartment image data storage mode of the vehicle interior monitoring system.

    摘要： A vehicle headlamp control method and apparatus includes providing an imaging sensor that senses light in spatially separated regions of a field of view forward of the vehicle. Light levels sensed in individual regions of the field of view are evaluated in order to identify light sources of interest, such as oncoming headlights and leading taillights. The vehicle's headlights are controlled in response to identifying such particular light sources or absence of such light sources. Spectral signatures of light sources may be examined in order to determine if the spectral signature matches that of particular light sources such as the spectral signatures of headlights or taillights. Sensed light levels may also be evaluated for their spatial distribution in order to identify light sources of interest.

    摘要： An image sensing system for a vehicle includes an imaging sensor and a logic and control circuit. The imaging sensor comprises a two-dimensional array of light sensing photosensor elements formed on a semiconductor substrate and is disposed at an interior portion of the vehicle proximate the windshield of the vehicle and has a forward field of view to the exterior of the vehicle through an area of the windshield. The logic and control circuit comprises an image processor for processing image data derived from the imaging sensor. The logic and control circuit generates at least one control output. The image sensing system detects lane markers on a road being traveled by the vehicle and present in the field of view of the imaging sensor.
