Abstract: A vision system of a vehicle includes a camera, a head unit and a plurality of circuit cards. The camera has a field of view exterior of the vehicle. The head unit includes a video display for displaying images derived from a video feed from the camera. The circuit cards each include at least one video line connector configured to communicate with a video feed from the camera. The head unit includes a circuit connector configured to connect to a selected one of the circuit cards. The circuit cards provide different processing functions via universal connection with the circuit connector of the head unit and the video feed from the camera. A selected circuit card connects to the circuit connector and receives the video feed from the camera and provides the processing functions associated with the selected circuit card and outputs an output signal to the circuit connector.

Abstract: A method includes disposing a spherical radar reflector at a location exterior a vehicle equipped with the vehicular sensing system. The vehicular sensing system includes at least two radar sensors disposed at the vehicle and a controller that processes received radio frequency (RF) signals received by the plurality of receivers of each radar sensor of the at least two radar sensors. Calibration RF signals are transmitted by at least one transmitting antenna of a plurality of transmitters of a first radar sensor and a second radar sensor the at least two radar sensors, and reflected first calibration RF signals are received by the plurality of receivers of the first radar sensor and the second radar sensor. Based on a distance between the first radar sensor, the second radar sensor, and the spherical reflector, the vehicular sensing system determines an orientation of the first radar sensor and the second radar sensor.

Abstract: A vehicular sensing system includes at least one radar sensor disposed at a vehicle and having a field of sensing exterior of the vehicle. The radar sensor includes multiple transmitting antennas and multiple receiving antennas. The at least one radar sensor is part of a suite of sensors that includes a forward viewing camera. Multiple scans of captured radar data are transferred from the at least one radar sensor to an electronic control unit. The system, via processing of transferred multiple scans of captured radar data and transferred image data, detects presence of a plurality of objects, generates a virtual antenna array with a virtual antenna aperture larger than a physical antenna aperture of the at least one radar sensor, and tracks the detected objects. The system, based at least in part on tracking detected objects, provides an output for at least one driving assist system of the vehicle.

Abstract: A method of calibrating a vehicular vision system includes mounting a camera at a vehicle moving along a vehicle assembly line. Responsive to processing of image data captured by the camera, ground features adjacent to the vehicle are determined and the determined ground features are tracked over two or more frames of captured image data using optical flow. A misalignment of the camera is determined via tracking the determined ground features as the vehicle moves along the straight path portion of the end of line test portion of the vehicle assembly line. Responsive to determination of misalignment of the camera at the vehicle, the vehicular vision system is calibrated using an assumption that the determined ground features lie in a plane parallel to a planar portion of a ground surface adjacent the straight path portion of the end of line test portion of the vehicle assembly line.

Abstract: A radar sensing system for a vehicle includes a radar sensor having a plurality of transmitting antennas and a plurality of receiving antennas. The transmitting antennas and the receiving antennas are arranged in multiple rows and columns of transmitting antennas and multiple rows and columns of receiving antennas. A control controls radar transmission by the transmitting antennas and receives outputs from the receiving antennas. The control applies two dimensional multiple input multiple output processing to outputs of the receiving antennas. With two dimensional multiple input multiple output processing applied to outputs of the receiving antennas, the transmitting antennas and the receiving antennas achieve an enhanced two dimensional virtual aperture.

Abstract: A method for calibrating a vehicular sensing system includes disposing the sensing system at a vehicle, with the sensing system including at least two radar sensors disposed at the vehicle so as to have respective fields of sensing exterior of the vehicle. At least one spherical radar reflector is disposed at a position exterior the vehicle where the fields of sensing of the at least two radar sensors overlap. A calibration mode of the sensing system is entered, and calibration radio waves are transmitted by at least one transmitter, and reflected calibration radio waves are received by receivers of the at least two radar sensors. The reflected calibration radio waves include the calibration radio waves reflected off the at least one spherical radar reflector. A controller calibrates the sensing system responsive to processing the received reflected calibration radio waves.

The control, responsive at least in part to processing at the processor of the received sensed radar data and the received vehicle motion estimation, determines different types of surfaces in the field of sensing of the at least one radar sensor.

Abstract: A method of calibrating a vehicular camera includes mounting a camera at a vehicle moving along a vehicle assembly line. Responsive to processing of image data captured by the camera, features at the ground adjacent to the vehicle are determined and the determined features are tracked over two or more frames of captured image data. Responsive to processing of frames of captured image data during movement of the vehicle along a straight path, a misalignment of the camera is determined. The misaligned camera is calibrated using an assumption that the determined ground features lie in a plane parallel to a planar portion of the ground surface adjacent the straight path portion of the vehicle assembly line. The determination of misalignment and the calibration of the camera are performed without use of a target pattern at the vehicle assembly line.
