摘要:
A vehicular rain sensor which senses precipitation at a vehicle window. The rain sensor comprises an imaging array sensor and a control. The imaging array sensor is directed at the vehicle window from inside the vehicle and comprises a camera device capable of imaging precipitation at a surface of the window. The camera is operable to image the precipitation at least in response to ambient light present at the window. The control responds to an output of the imaging array sensor in order to indicate precipitation at the surface of the window. The control determines the presence of precipitation via spatial filtering of the image received by the camera device.

A moisture sensing assembly for controlling vehicle accessories such as windshield wipers is mounted on the inner surface of a vehicle window or windshield for detecting moisture on the outer window surface. A plurality of infrared energy emitting diodes and a sensor for receiving reflected infrared energy from the window and any moisture thereon are mounted at predetermined angles and spacing in a support. The support is biased against the window and enclosed in a protective housing detachably mounted to a window mounted plate preferably adjacent a rearview mirror on the front windshield. The support preferably includes an infrared energy monitoring sensor adjacent the emitting diodes which may be combined with or separate from an ambient infrared energy sensor. The monitoring and ambient sensors provide reference energy levels allowing compensation for varying diode output due to temperature and age and varying external vehicle light conditions.

A vehicular imaging and display system includes a rear backup camera at a rear portion of a vehicle, a video processor for processing image data captured by the rear camera, and a video display screen responsive to the video processor to display video images. During a reversing maneuver of the equipped vehicle, the video display screen displays video images captured by the rear camera. During forward travel of the equipped vehicle, the video display screen is operable to display images representative of a portion of the field of view of the rear camera to display images representative of an area sideward of the equipped vehicle responsive to at least one of (a) actuation of a turn signal indicator of the vehicle, (b) detection of a vehicle in a side lane adjacent to the equipped vehicle and (c) a lane departure warning system of the vehicle.

A vision system for a vehicle includes at least a first imager, an image processor, and at least a second imager. The first imager has a field of view through the windshield of the vehicle in the direction of forward travel of the vehicle. The second imager captures video images of a scene occurring exteriorly and rearwardly of the vehicle. When the vehicle is executing a reversing maneuver, the image processor processes image data captured by the second imager to detect objects in the exterior scene to assist the driver in reversing the vehicle, and when the vehicle is traveling forward, the image processor and the first imager are part of at least one of (i) a headlamp control system of the vehicle, (ii) a rain sensing system of the vehicle, (iii) a lane departure warning system of the vehicle and (iv) a traffic sign recognition system of the vehicle.
摘要:
An image sensing system for a vehicle includes an imaging sensor comprising a two-dimensional array of light sensing photosensor elements, preferably formed on a semiconductor substrate, and a logic and control circuit comprising an image processor for processing image data derived from the imaging sensor. The logic and control circuit generates at least one control output for controlling at least one light of the vehicle. The imaging sensor 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 at least one control output preferably controls at least one of (i) a beam state of a headlight; (ii) a beam aim of a headlight; (iii) a beam pattern of a headlight and (iv) a beam intensity of a headlight.

A headlamp control system for a vehicle includes an imaging array sensor, which has a field of view forward of the vehicle, and a control that processes images captured by the imagine array sensor. The control is operable to detect light sources in the field of view and to determine an activity level in the field of view in response to a quantity of light sources detected. The control is operable to control a headlamp of the vehicle in response to identification of at least one of a headlamp of another vehicle and a taillight of another vehicle and in response to the activity level. The control may be operable to process the captured images to detect lane markers or precipitation in the field of view and may control a steering system of the vehicle or a wiper motor of the vehicle in response to such image processing.

An interior rearview mirror system suitable for use in a vehicle includes a interior rearview mirror assembly adapted for attachment to an interior portion of the vehicle. The interior rearview mirror assembly includes a housing and a reflective element included within the housing. The mirror system further includes a video device (which includes an imaging sensor) and a control. The imaging sensor is positioned at the interior rearview mirror assembly and has a field of view forward and through the windshield. The imaging sensor is operable to at least sense precipitation at an interior and/or exterior surface of the windshield. The control receives a signal from the imaging sensor and is operable to control at least one of a headlamp of the vehicle, a windshield wiper of the vehicle, a defogging system of the vehicle and a movable window of the vehicle in response to the signal.

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:
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.
