  • Patent number: 9789743
    Abstract: A vehicle suspension structure includes a suspension arm and a ball joint. The suspension arm is connected between a suspension member and a vehicle-widthwise outer side end connected to a vehicle wheel. The ball joint connects the suspension arm and the vehicle wheel. When the vehicle receives an impact in the longitudinal direction, a socket of the ball joint pivots relative to a ball as the suspension arm deforms, and a flange portion on an open side of the socket interferes with a stud shaft of the ball joint. The interference causes the flange portion to deform and the ball to come out of the socket to undo the link with the vehicle wheel by the ball joint. Upon becoming unlinked, the vehicle wheel moves toward the vehicle-widthwise outer side and interference with the rear vehicle body is suppressed to limit deformation of the vehicle body.

  • Publication number: 20170140229
    Abstract: A position of a moving object is reliably detected with high accuracy using only an image around a vehicle. A rear camera mounted on a vehicle obtains an original image around the vehicle, a movement region detector detects a moving object from the original image, and a difference calculator detects the moving object from a bird's-eye view image of the vehicle generated by a bird's-eye view image processor. A moving object position identifying part identifies a position of the moving object based on a distance from the vehicle to the moving object detected by the movement region detector or the difference calculator, a lateral direction position of the moving object, and an actual width of the moving object detected by the movement region detector when a detected object determination part determines that the moving objects detected by the movement region detector and the difference calculator are the same moving object.
