  • Patent number: 9139147
    Abstract: In order to provide a front structure, of a vehicle, which prevents reduction in efficiency in cooling an auxiliary component, by using intake air, and suppresses damage to the auxiliary component, which are caused by a millimeter-wave radar in the event of collision, a front structure of the vehicle includes a front right side radar for transmitting and receiving a radio wave to detect obstacles to a front right side of the vehicle, a front left side radar for transmitting and receiving a radio wave to detect obstacles to a front left side of the vehicle, a bumper reinforcement, crash boxes at the left and the right, and a condenser which is cooled by intake air. The front right side radar is arranged to a side farther out than a right end of the condenser, and the front left side radar is arranged to a side farther out than a right end of the condenser.

  • Patent number: 8744743
    Abstract: Provided is a front structure of a vehicle wherein damage on auxiliary equipment by a millimeter-wave radar is limited at the time of collision, and cooling efficiency for auxiliary equipment using traveling wind is not reduced. A front structure of a vehicle comprises a front right side radar for detecting an obstacle on the front right side of a vehicle by transmitting/receiving a radio wave, a front left side radar for detecting an obstacle on the front left side of a vehicle by transmitting/receiving a radio wave, a bumper reinforcement, right and left crush boxes, and a condenser cooled by traveling wind, wherein the front right side radar is disposed on the outboard side of the right end of the condenser, and the front left side radar is disposed on the outboard side of the left end of the condenser.

  • Patent number: 8174432
    Abstract: A radar apparatus mounted in a vehicle includes an inward bent surface and a radar device. The inward bent surface is formed in a lower portion of a bumper of the vehicle, and curves inward with a higher degree of curvature in a horizontal plane than a bumper surface of an upper portion of the inward bent surface. The radar device is placed behind the inward bent surface so that a beam axis of the radar device penetrates the inward bent surface.
