Abstract: A vision system of a vehicle includes at least one camera configured to be disposed at a vehicle so as to have a field of view exterior and forward of the vehicle, and at least one other sensor configured to be disposed at a vehicle so as to have a sensing field exterior of the vehicle. A processor is operable to process data captured by the camera and the sensor. Responsive to processing of captured data, the processor determines an object present in the sensing field of the sensor. Responsive to processing of image data captured by the camera, the processor determines lane markings present in the field of view of the camera and forward of the vehicle. The processor receives object hypotheses, sensor properties and vehicle data as inputs and performs a data transformation to generate fused object hypotheses.

Abstract: A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. An image processor is operable to process image data captured by the camera. The image processor is operable to determine lane markers on a road on which the vehicle is traveling. The image processor processes intensity gradient information of captured image data to determine lane markers, and, responsive to processing of captured image data, the image processor is operable to detect straight or curved lane markers. The image processor is operable to adapt the processing of lane marker image data in subsequent frames of captured image data responsive to image processing of lane marker image data in previous frames of captured image data.

Abstract: A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. An image processor is operable to process image data captured by the camera. The image processor, responsive to image processing of captured image data when the camera is disposed at the vehicle, is operable to determine the presence of a pedestrian in the field of view of the camera. The vision system may utilize a linear classifier to identify areas where a pedestrian is more likely to be present for enhanced processing of those areas. The vision system may utilize a Histogram Intersection Kernel classifier for enhanced processing of identified areas. The vision system may utilize detection area filtering to reduce processing of image data representative of areas of the field of view where a pedestrian is not likely to be present.

Abstract: A vehicular control system includes a plurality of sensors disposed at a vehicle so as to have a combined field of sensing forward, rearward and sideward of the vehicle. Data captured by the sensors as the vehicle moves along a road is processed at a control for detecting objects present exterior the vehicle. The control designates a plurality of locations within the fields of sensing. As the vehicle moves along the road, the control increases a value for each designated location when an object is detected at that designated location, and decreases the value for each designated location when an object is not detected at that designated location, and generates an object map based on values for the designated locations. The greater the value for a particular designated location, the greater the probability an object is present at that particular designated location.

Abstract: A vehicular trailer angle detection system includes a camera disposed at a rear portion of a vehicle. The system determines, via processing of frames of image data captured by the camera, features of a trailer present rearward of the vehicle and hitched to the vehicle by determining features that have similar position changes between a current frame of image data captured by the camera and a previous frame of image data captured by the camera. Responsive to movement of the trailer relative to the vehicle, and via processing of captured frames of image data, the system tracks determined features over multiple captured frames of image data for different positions of the trailer relative to the vehicle. The system determines angle of the trailer relative to the vehicle based at least in part on tracking of determined features of the trailer over multiple captured frames of image data.

Abstract: A method for determining a safe state for a vehicle includes disposing a camera at a vehicle and disposing an electronic control unit (ECU) at the vehicle. Image data is captured via the camera and provided to the ECU. An image processor of the ECU processes captured image data. A condition is determined via processing at the image processor of the ECU captured image data. The condition comprises a shadow present in the field of view of the camera within ten frames of captured image data or a damaged condition of the imager within two minutes of operation of the camera. The condition is indicative of a condition where processing of captured image data degrades in performance. The ECU determines a safe state for the vehicle responsive to determining the condition.

Abstract: A vehicular vision system includes a camera disposed at an in-cabin side of a windshield of a vehicle and viewing forward of the vehicle. The vehicular vision system, responsive at least in part to image processing of multiple frames of captured image data, detects an object present exterior of the vehicle that is moving relative to the vehicle. The system, when the vehicle is moving, and based at least in part to received vehicle motion data indicative of motion of the vehicle when the vehicle is moving and image processing of multiple frames of captured image data, (i) estimates object trajectory of the detected object based at least in part on corresponding object features present in multiple frames of image data captured by the camera and (ii) determines motion of the detected object relative to the moving vehicle based on the estimated object trajectory.

Abstract: A vehicular vision system includes a plurality of cameras disposed at a vehicle and capturing image data as the equipped vehicle is driven along a traffic lane of a road. Captured image data is processed to detect a rearward-approaching vehicle and determine a path of travel of the detected rearward-approaching vehicle. Responsive to determining that the path of travel of the detected rearward-approaching vehicle is along a side traffic lane adjacent to the traffic lane along which the equipped vehicle is driven, the vehicular vision system (i) displays at a video display screen video images derived at least from image data captured by the side camera that is at the side portion of the equipped vehicle that is adjacent to the side traffic lane and (ii) overlays a transparent graphic overlay overlaying the displayed video images that is based on the determined path of travel of the detected rearward-approaching vehicle.
