摘要:
A vehicle headlamp control method and apparatus includes providing an imaging sensor (14) 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 by a sensor array (38) are evaluated in order to identify light sources of interest, such as oncoming headlights and leading taillights. The vehicle's headlights (18) are controlled by lighting control logic (16) 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 distributions in order to identify light sources of interest.

An electronic compass is described for use in vehicles (26). The compass employs a magnetoresistive sensor (10, 10') for sensing the earth magnetic field and the sensor is operated in alternate set/reset bias modes. The compass is provided with deviation compensation by a closed loop system including measurement of the sensor output signals and an offset current strap for nullifying the vehicle deviation field.

摘要:
A system apparatus, means and method for controlling variable reflectance mirrors in response to drive voltages applied thereto, and for monitoring a vehicle interior. The system includes a light sensing device and a control circuit (26). The light sensing device comprises a photosensor array (32) having a field of view encompassing a vehicle interior. The logic and control circuit (34) determines a background light signal indicative of light levels incident on the photosensor elements and determines a peak light signal in three different zones or sub-arrays of the photosensor array. The peak light signals and a common background light signal are used to determine control signals for independently controlling the reflectance level of a plurality of mirrors (4, 5), or alternativeley the segments of a mirror. The logic and control circuit (34) also determines a vehicle intrusion condition and stores image data in memory in the compartment image data storage mode of the vehicle interior monitoring system.
摘要:
A vehicle rain sensor system for detecting precipitation on an exterior surface of a window (19) including an illumination sensor (36) that is decoupled from the window. The illumination sensor is preferably an imaging array sensor which communicates a signal control (42) which further determines whether rain is present on the window. The control preferably includes an edge detection (44) for detecting edges of precipitation droplets on the window and activating the windshield wipers (22) of the vehicle when the number of edges detected exceeds a predetermined threshold value. The rain sensor system may further include a polarizing filter (62) and an illumination source (55), such that rain sensor system may not only prevent false signals of rain when only fog is present on an interior surface (28) on the window, but also allows the rains sensor system to actually detect fog particles on an interior surface on the window, thereby allowing the control to further be connected to a ventilation blower within the vehicle for the purpose of activating the blower to eliminate the fog.

An accessory system for a vehicle includes an interior rearview mirror assembly (10) and a display screen (20) that is extendable and retractable relative to a casing. The display screen is slidably mounted at the casing and slidable in a direction generally parallel to a length axis of the reflective element between a non-use position, where the video display screen is positioned substantially within the casing, and a use position, where the video display screen is substantially extended from a side of the casing for viewing. The display screen may be automatically extended in response to an activating event. The accessory system may include an accessory module (50), which may comprise multiple sub-modules that may be selected to provide the desired accessory content to the accessory module.
摘要:
A rearview vision system for a vehicle includes an image capture device mounted at the rear of the vehicle and having a field of view directed rearwardly of the vehicle. A display system is viewable by a driver of the vehicle. The display system displays a rearward image output of the image capture device. A graphic overlay is superimposed on the rearward image when the gear actuator of the vehicle selects a reverse gear. The graphic overlay may include indicia of the anticipated path of travel of the vehicle. The graphic overlay may be disabled when the gear actuator of the vehicle is not in reverse gear.
摘要:
An information display mirror system suitable for use in a vehicle includes an interior rearview mirror assembly configured for mounting at an interior portion of a vehicle and having a casing, a mirror support arm and a reflective element. The interior rearview mirror assembly includes an information display screen disposed separate from and independent of and lateral of the reflective element at a portion of the casing closer to a seating location of the vehicle driver or at a portion of the casing further from a seating location of the vehicle driver. The information display screen may be a touch-sensitive information display screen that displays information responsive to the driver of the vehicle at least one of touching its viewing surface and positioning a finger proximate its viewing surface.

摘要:
An interior rearview mirror system (10) includes a compass system (18) and a display (20). The compass system (18) is operable to display information indicative of a directional heading of the reflective coating of a mirror reflective element (16) and includes illumination sources (24) positioned behind and generally aligned with corresponding ones of the ports. Each of the illumination sources (24) may be energized to project illumination through a respective one of the ports such that the ports are backlit by the respective illumination sources (24) in order to convey the directional information to the driver of the vehicle. The system may include a microprocessor (119) operable to control each illumination source via a respective wire connected between the microprocessor (119) and each illumination source (24). The compass system (18) may utilize a global positioning system for vehicle direction determination.
