    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 transmitting antennas transmit signals and the receiving antennas receive the signals reflected off objects. Multiple scans of radar data are received at an electronic control unit (ECU) and processed at a processor of the ECU. The ECU detects presence of a plurality of objects exterior the equipped vehicle and within the field of sensing of the at least one radar sensor. The ECU, responsive at least in part to processing at the processor of the received multiple scans of captured radar data and received vehicle motion estimation, tracks objects detected in the received multiple scans over two or more scans.

    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.

    Abstract: A vehicular radar sensing system includes a camera and at least one radar sensor having a plurality of transmitting antennas and a plurality of receiving antennas. Individual transmitting antennas are arranged in multiple rows, and individual receiving antennas are arranged in multiple columns. The multiple rows of transmitting antennas include first and second rows of transmitting antennas, each row having at least four transmitting antennas. Each column of the multiple columns of receiving antennas comprises at least four receiving antennas. The multiple columns of receiving antennas are disposed between the first row of transmitting antennas and the second row of transmitting antennas. The vehicular radar sensing system applies two dimensional multiple input multiple output processing to outputs of the receiving antennas. The vehicular radar sensing system, responsive to processing of outputs of the receiving antennas, detects at least one object present forward of the vehicle for a driving assist system.

    Abstract: A vehicular radar sensing system includes a radar sensor disposed at a vehicle so as to sense exterior of the vehicle and having at least one transmitter that transmits radio signals and at least one receiver that receive radio signals. The radar sensor includes at least one wave guide antenna, a PCB, and a processor disposed on an inboard side of the PCB and operable to process radio signals received by the at least one receiver. The wave guide antenna includes a first wave guide slot disposed at the inboard side of the PCB that guides the radio signals to the at least one receiver or from the at least one transmitter, a second wave guide slot that guides the radio signals to and from the environment, and an air wave guide that guides the radio signals between the first wave guide slot and the second wave guide slot.

    Abstract: A vehicular radar sensing system includes a radar sensor disposed at a vehicle. The radar sensor includes a waveguide antenna and a printed circuit board (PCB) with an inboard side and an outboard side. A processor is disposed at the inboard side of the PCB and the waveguide antenna is disposed at the outboard side of the PCB. The waveguide antenna is partially disposed within a cavity at the outboard side of the PCB. Radio frequency signals are electrically communicated between the processor and the waveguide antenna through only a portion of the PCB. The waveguide antenna (i) guides the transmitted radio signals from the transmitter to the exterior environment and (ii) guides reflected radio signals from the exterior environment to the receiver.

    Abstract: A vehicular radar sensing system includes a radar sensor disposed at a vehicle. The radar sensor includes a plurality of antennas, which includes a plurality of transmitting antennas and a plurality of receiving antennas. The radar sensor transmits multiple outputs via the plurality of transmitting antennas and receives multiple inputs via the plurality of receiving antennas. The plurality of antennas includes a plurality of sets of antennas, each set having a V shape or an X shape, and with each of the shaped sets of antennas having an apex. A signal feed is provided to the apex of each of the shaped sets of antennas. Outputs of the receiving antennas are communicated to a processor, and the processor, responsive to the outputs of the receiving antennas, determines presence of one or more objects exterior the vehicle and within the field of sensing of the radar sensor.

    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.
