    Abstract: A vehicle includes a plurality of on-vehicle cameras, and a controller executes a method to evaluate a travel surface by capturing images for fields of view of the respective cameras. Corresponding regions of interest for the images are identified, wherein each of the regions of interest is associated with the portion of the field of view of the respective camera that includes the travel surface. Portions of the images are extracted, wherein each extracted portion is associated with the region of interest in the portion of the field of view of the respective camera that includes the travel surface and wherein one extracted portion of the respective image includes the sky. The extracted portions of the images are compiled into a composite image datafile, and an image analysis of the composite image datafile is executed to determine a travel surface state. The travel surface state is communicated to another controller.

    Abstract: A vehicle guidance system facilitates maneuvering of an autonomous vehicle with respect to an object in a scene. The vehicle includes a steering apparatus having a range of angular positions and a multitude of actuators for controlling the dynamics of the vehicle. The system includes a steering angle sensor, a camera device, and a video processing module. The sensor is configured to monitor the angular position of the wheel. The device is configured to capture an original image of a scene having the object. The module is configured to receive and process the original image from the device, detect the object in the original image, receive and process the angular position from the sensor, generate a dynamic trajectory based on at least the angular position, orientate the dynamic trajectory with regard to the object, and operate at least one of the actuators to guide the vehicle along the dynamic trajectory.

    Abstract: A vehicle includes a vision system configured to output a signal indicative of exterior conditions in a vicinity of the vehicle and a temperature sensor configured to output a signal indicative of an interior temperature of the vehicle. The vehicle also includes a plurality of articulable openings arranged to allow fluid flow communication between an interior and an exterior of the vehicle. The vehicle further includes a controller programmed to adjust at least one articulable opening toward an open position in response to the interior temperature exceeding a temperature threshold. The controller is also programmed to adjust at least one articulable opening toward a closed position in response to detection via the vision system of a threat condition in the vicinity of the vehicle.

    Abstract: Systems and method are provided for a towing vehicle towing a trailer having at least one imaging device. A method includes: receiving, from a first imaging device coupled to the trailer, a first image stream having a plurality of first images; receiving, from a second imaging device coupled to the vehicle, a second image stream having a plurality of second images; determining, at least one common feature between a first image of the first images and a second image of the second images; determining a first distance from the first imaging device to the at least one common feature and a second distance from the second imaging device to the at least one common feature; and determining, a position of the first imaging device relative to the vehicle based on the first distance, the second distance and a known position and pose of the second imaging device.

    Abstract: A method of identifying a snow covered road includes creating a forward image of a road surface. The forward image is analyzed to detect a tire track in the forward image. When a tire track is detected in the forward image, a message indicating a snow covered road surface is signaled. When a tire track is not detected in the forward image, a rearward image, a left side image, and a right side image are created. The rearward image, the left side image, and the right side image are analyzed to detect a tire track in at least one of the rearward image, the right side image, and the left side image. A message indicating a snow covered road surface is signaled when a tire track is detected in one of the rearward image, the left side image, or the right side image.

    Abstract: A system and method for determining when to display frontal curb view images to a driver of a vehicle, and what types of images to display. A variety of factors—such as vehicle speed, GPS/location data, the existence of a curb in forward-view images, and vehicle driving history—are evaluated as potential triggers for the curb view display, which is intended for situations where the driver is pulling the vehicle into a parking spot which is bounded in front by a curb or other structure. When forward curb-view display is triggered, a second evaluation is performed to determine what image or images to display which will provide the best view of the vehicle's position relative to the curb. The selected images are digitally synthesized or enhanced, and displayed on a console-mounted or in-dash display device.
