An imaging system for a vehicle includes an imaging device having a field of view exteriorly and forward of the vehicle in its direction of travel, and an image processor operable to process the captured images in accordance with an algorithm. The algorithm comprises a sign recognition routine and a character recognition routine. The image processor processes the image data captured by the imaging device to detect signs in the field of view of the imaging device and applies the sign recognition routine to determine a sign type of the detected sign. The image processor is operable to apply the character recognition routine to the image data to determine information on the detected sign. The image processor applies the character recognition routine to the captured images in response to an output of the sign recognition routine being indicative of the detected sign being a sign type of interest.

Imaging system for vehicle

A forward-facing vision system for a vehicle includes a forward-facing camera disposed in a windshield electronics module attached at a windshield of the vehicle and viewing through the windshield. A control includes a processor that, responsive to processing of captured image data, detects taillights of leading vehicles during nighttime conditions and, responsive to processing of captured image data, detects lane markers on a road being traveled by the vehicle. The control, responsive to lane marker detection and a determination that the vehicle is drifting out of a traffic lane, may control a steering system of the vehicle to mitigate such drifting, with the steering system manually controllable by a driver of the vehicle irrespective of control by the control. The processor, based at least in part on detection of lane markers via processing of captured image data, determines curvature of the road being traveled by the vehicle.

Vision system for vehicle

A vehicular vision system includes a camera having a lens and a CMOS photosensor array having a plurality of photosensor elements. The camera is disposed at an interior portion of a vehicle equipped with the vehicular vision system. The camera one of (i) views exterior of the equipped vehicle through the windshield of the equipped vehicle and forward of the equipped vehicle and (ii) views from the windshield of the equipped vehicle into the interior cabin of the equipped vehicle. A control includes an image processor that processes image data captured by the photosensor array. The image processor processes captured image data to detect an object viewed by the camera. The photosensor array is operable at a plurality of exposure periods and at least one exposure period of the plurality of exposure periods is dynamically variable.

An alert system for a vehicle includes a video display, an interior visual alert device disposed at an interior rearview mirror assembly, a driver side visual alert device disposed at a driver side exterior rearview mirror assembly and a passenger side visual alert device disposed at a passenger side exterior rearview mirror assembly. A control is operable to activate at least one of the alert devices in response to a detection of an object rearward of the vehicle. The alert devices are viewable by the driver of the vehicle when activated and are operable to guide or prompt the driver to check the images captured by a rearward facing camera and displayed in the vehicle cabin by the video display so that the driver can verify the nature and type of a potential hazard rearward of the vehicle.

A driver assistance system for a vehicle includes an imaging device having a field of view forward of a vehicle and in a direction of travel of the equipped vehicle, an image processor operable to process image data captured by the imaging device, and a global positioning system operable to determine a geographical location of the vehicle. The equipped vehicle includes an adaptive speed control system for controlling the speed of the equipped vehicle. The adaptive speed control system may reduce the speed of the equipped vehicle responsive at least in part to a detection of a curve in the road ahead of the equipped vehicle via processing by the image processor of image data captured by the imaging device.

Driver assistance system for vehicle

The invention relates to a device for improving the visibility conditions in a motor vehicle, having a radiation source for infrared radiation for irradiating the surroundings of the vehicle, having an infrared-sensitive camera for taking images of at least part of the irradiated surroundings, having a display unit for displaying collected image data, and having a control unit for controlling the device. In this context, the control unit is embodied in such a way that, while the device is operating, the display represents image data in a chronologically limited fashion by means of controlled switching on and switching off, and in the process the switching off of the representation of images on the display is made gradual. The gradual switching off is carried out in particular by changing the brightness limiting values, the contrast limiting values and/or by increasing or reducing the noise of the image data to be represented. Furthermore, the gradual switching off preferably has a time-dependent or velocity-dependent profile. This device ensures that the vehicle with the device operates in a very safe way for the user.

The headlamp has an asymmetric array (5) of LED chips (1) supported by a common carrier, combined with an optical element (2), acting as a common collector lens with the LED chips positioned in its focal plane, for providing a LED module (3). The asymmetrical array is obtained by omission of LED chips from a symmetrical array.

Automobile headlamp using LED module with asymmetric LED chip array for providing headlamp beam with asymmetric light distribution

The invention relates to a headlight 1 in particular based on the projection principle. The headlight has a semiconductor light source 4, which is arranged at the focal point of the reflector 2 and is connected to a cooling element 5. This cooling element 5 extends from the semiconductor light source 4 to the transparent lens 3, through which the light that is reflected by the reflector 2 is emitted, passes through the transparent lens 3, and projects beyond it. This arrangement of a semiconductor light source 4, a cooling element 5 and a transparent lens 3 ensures that the light source 4 is cooled effectively. In addition, the arrangement and the form of the cooling element 5 ensure that the cooling element 5 does not shadow, or only slightly shadows, the reflected light. This leads to a high light yield from the headlight 1 according to the invention, and to a long life.

Headlight for a vehicle

The invention relates to a device for controlling a low beam (L) of a vehicle (1), comprising at least one headlight (1.1, 1.2) having at least one light source, means for pivoting a generated light distribution (L1, L2), and at least one optical element (1.1.1, 1.2.1), by means of which a beam path of the light distribution (L1, L2) can be adjusted, wherein the optical element (1.1.1, 1.2.1) has a light passage opening (LO) and can be pivoted into an optical axis (oA) of the light source if a hazardous situation is detected, wherein a beam of the light distribution (L1, L2) is bounded and/or deflected in such a way that a bounded light area (A) having an outer shape of the light passage opening (LO) can be produced in a predeterminable area in front of the vehicle (1). According to the invention, the optical element (1.1.1, 1.2.1) has further light passage structures, which are arranged such that, starting from the light passage opening (LO), a "high beam" (LF) light pattern or a "partial high beam" (LT) light pattern and thereafter the "high beam" (LF) light pattern can be produced by means of at least one of the further light passage structures by rotating, pivoting, and/or sliding the optical element (1.1.1, 1.2.1) in a direction and a "highway" (LA) light pattern and thereafter a "secondary road" (LL) light pattern can be produced by means of at least one of the further light passage structures by rotating, pivoting, and/or sliding the optical element (1.1.1, 1.2.1) in an opposite direction.
