  • Patent number: 10217364
    Abstract: A lane assistance system of a host vehicle for reacting to fast and extremely fast approaching vehicles includes a rear radar sensing unit having a sensor and an electronic controller. The electronic controller determines the distance and relative velocity of the fast approaching vehicle to the host vehicle. Further, depending on the closeness of the approaching vehicle, the lane of the approaching vehicle is determined from angular resolution of the radar signal. When the vehicle is approaching at an extremely fast rate and the angular resolution of the radar signal is not capable of determining an exact relative lane of the approaching vehicle due to the vehicle being too far away, the assistance system warns against or prevents lane changes by the host vehicle.

  • Patent number: 10069212
    Abstract: An antenna array includes a first patch antenna and a second patch antenna which are oriented mutually in parallel. Each patch antenna includes a linear array of radiation elements. Adjacent radiation elements within each patch antenna are equidistantly spaced apart and are interconnected. In addition, a connecting line between adjacent first ends of the two patch antennas is provided, and the two second ends of the patch antennas are each adapted for transfer of an electrical oscillation. The spacings between the adjacent radiation elements of the first patch antenna are greater than the spacings between the adjacent radiation elements of the second patch antenna.

  • Patent number: 10018715
    Abstract: A radar sensor for vehicles, including a group antenna, having a linear array of antenna elements, a feed unit for feeding transmission signals having a settable phase relationship into the antenna elements, a control unit controlling the feed unit, and an evaluation device evaluating received radar echoes and angle-resolving locating of objects. The group antenna includes at least two non-interleaved subgroups, the feed unit supplies in-phase transmission signals to the elements, while the transmission signals for the various subgroups have a settable phase difference, the control unit periodically changes the settable phase difference so that the transmission signals have a base phase difference in one measuring cycle and a phase difference in another measuring cycle which differs by a fixed absolute value from the base difference. The control unit sets the base difference based on levels of the received radar echoes to maximize the level difference between the measuring cycles.

  • Publication number: 20170212215
    Abstract: A method and apparatus for determining misalignment of a radar sensor unit mounted to a vehicle includes providing targets on an alignment apparatus. A vehicle is located at predetermined location on a test station an exact given distance from the alignment apparatus. The actual locations and distances of the targets from each other and from radar sensor unit of the vehicle at the test station are known and pre-stored. At least one target is a greater distance from the vehicle than the other targets. The targets receive and return a radar wave from the radar sensor unit. The radar sensor unit determines locations and distances of the targets and compares with the given or actual locations and distances of the targets to determine misalignment of the radar sensor unit. A calibration program automatically calibrates azimuth and elevation to adjust for misalignment.

  • Patent number: 9638796
    Abstract: A radar sensor for motor vehicles, having a transmitting antenna in the form of a planar group antenna having multiple antenna elements situated side by side on a shared planar substrate, and having a feed network and a switching device for supplying microwave power to the antenna elements. The antenna elements are situated at equal distances in at least one row; the feed network is designed for supplying the antenna elements with the microwave power having a phase shift which increases at constant increments from one end of the row to the other; and the switching device is designed for controlling the supply of the microwave power to the antenna elements in such a way that, depending on the operating mode, the supply is implemented in a mirror-inverted fashion from opposite ends of the at least one row.
