  • Patent number: 12510659
    Abstract: A vehicular radar sensing system includes a radar sensor disposed at a vehicle and having a printed circuit board (PCB). The radar sensor includes an antenna structure having a transmitting port for a transmitter of the radar sensor and a receiving port for a receiver of the radar sensor. The antenna structure includes a wall structure that extends from a first side of the antenna structure toward a first side of the PCB to at least partially define a transmitting area and a receiving area to isolate radio frequency signals at the transmitting area from radio frequency signals at the receiving area. The antenna structure includes a transmitting wave-guide that guides transmitted radio signals from the transmitter through the transmitting area to the transmitting port. The antenna structure includes a receiving wave-guide that guides received radio signals from the receiving port through the receiving area to the receiver.

  • Patent number: 12487355
    Abstract: A vehicular sensing system includes a radar sensor disposed at a first vehicle and operable to sense objects within a field of sensing of the radar sensor. Responsive to a sensing system of a second vehicle detecting an object while the detected object is not within the field of sensing of the radar sensor of the first vehicle, the vehicular sensing system receives from the second vehicle one or more characteristics of the detected object while the detected object is not within the field of sensing of the radar sensor of the first vehicle. The vehicular sensing system, responsive to receiving the one or more characteristics of the detected object from the second vehicle, adjusts sensing by the radar sensor of the first vehicle based at least in part on the received one or more characteristics of the detected object.

  • Patent number: 12345809
    Abstract: A vehicular sensing system includes a radar sensor including a radar module having a plurality of transmitters and a plurality of receivers. The radar module includes a plurality of facets, with each facet arranged at an obtuse angle relative to an adjacent facet and having a respective transmitter and a respective receiver disposed thereat. The respective transmitter and the respective receiver of each facet have a respective field of sensing and a respective principal sensing axis that is perpendicular to the respective facet. The vehicular sensing system, responsive to processing by the data processor of sensor data captured by the radar sensor, determines presence of a target object within a field of sensing of the radar sensor. Responsive to determining presence of the object, the vehicular sensing system controls a system of the vehicle based on the determined presence of the object.

  • Publication number: 20250138143
    Abstract: A vehicular radar sensor includes transmitters and receivers, a printed circuit board (PCB), and a radome at least partially enclosing (i) the PCB, (ii) the transmitters and (iii) the receivers. The radome includes an internal surface nearest the PCB and an external surface farthest from the PCB. The radome includes a plurality of cavities at the internal side of the radome that extend partially but not entirely through a thickness of the radome. A first portion of the radio signals passes through the plurality of cavities when passing through the radome to be received by the receivers, and a second portion of the radio signals does not pass through the plurality of cavities when passing through the radome to be received at the receivers. Radar data captured by the vehicular radar sensor is based on (i) the first portion of radio signals and (ii) the second portion of radio signals.

  • Publication number: 20250052881
    Abstract: A vehicular radar sensing system includes a radar sensor and a reflector disposed at an interior cabin of a vehicle. The reflector includes a plurality of radar-reflective portions. Transmitted radio signals from the radar sensor reflect off the radar-reflective portions of the reflector toward respective regions of interest of a plurality of regions of interest within the vehicle. Each radar-reflective portion of the plurality of radar-reflective portions of the reflector reflects transmitted radio signals toward a different respective region of interest of the plurality of regions of interest. Received radio signals include radio signals that reflect off the reflector toward the radar sensor. The vehicular radar sensing system, responsive to processing of captured radar data, determines presence of an occupant of the vehicle at one of the regions of interest of the plurality of regions of interest.

  • Publication number: 20250028042
    Abstract: A vehicular radar sensing system includes a radar sensor disposed at a vehicle. The radar sensor includes a plurality of facets, each having an inboard surface facing toward the vehicle and an outboard surface facing away from the vehicle. A respective transmitter and a respective receiver of each facet operate to have a respective field of sensing with a respective principal sensing axis that is perpendicular to the respective facet. The vehicular sensing system, via processing of captured sensor data, (i) determines presence of a first object within a first respective field of sensing and (ii) determines presence of a second object within a second respective field of sensing. The vehicular sensing system, responsive to determining presence of the first object and the second object, controls a system of the vehicle based on the determined presence of the first object and the second object.
