  • Patent number: 11577719
    Abstract: An autonomous driving control apparatus installable in a vehicle includes a path determining section, an obstacle determining section that determines whether an obstacle on the planned driving path is a passage acceptable obstacle or a passage unacceptable obstacle, the passage acceptable obstacle being previously set as an obstacle that the vehicle is allowed to come into contact with while passing, the passage unacceptable obstacle being previously set as an obstacle that the vehicle is not allowed to come into contact with while passing, and a control instructing section that gives an instruction of control to a maneuver controller to perform at least one of controlling a speed of the vehicle and controlling a steering of the vehicle to control a maneuver of the vehicle. If the obstacle is determined to be the passage acceptable obstacle, the control instructing section gives an instruction of the control to pass over the obstacle.

  • Publication number: 20180224852
    Abstract: An auto-drive apparatus includes a condition determiner for determining whether an auto-drive start condition of a vehicle is satisfied based on a detection of a boarding action by a user. When no destination has been set at a time when the auto-drive start condition is satisfied, a temporary destination setter sets a temporary destination, which is a position on a nearby road that is reachable in a minimum travel time or via a shortest travel distance from a current vehicle position. An auto-drive processor plans a route to the temporary destination and starts the auto-drive of the vehicle toward the temporary destination.

  • Patent number: 9506522
    Abstract: A fluid-filled vibration device including a pressure receiving chamber and an equilibrium chamber communicated by an orifice passage and a connecting hole provided on a partition member partitioning the two chambers. The connecting hole is closed by a closing rubber elastic plate to which pressures of the two chambers are applied from the respective sides. The closing rubber elastic plate includes at its outer circumference edge part abutting retaining parts held by the partition member, an elastic deformation area which is provided circumferentially between the abutting retaining parts and elastically deformed to open the connecting hole, and a mass part provided at a circumference direction intermediate part of the elastic deformation area to constitute a mass-spring system together. The resonance frequency of the system is tuned to 50 Hz or greater and set higher than a tuning frequency of the orifice passage.

  • Patent number: 9168867
    Abstract: A pedestrian notification apparatus, which is configured to be used in a vehicle, includes an ambient object detector, a notification target detector and a notifier. The ambient object detector is configured to detect ambient objects present around the vehicle. The notification target detector is configured to detect a notification target pedestrian based on the detection results of the ambient object detector. The notifier is configured to notify the notification target pedestrian that the notification target pedestrian has been detected by the notification target detector.

  • Publication number: 20140132404
    Abstract: In a pedestrian collision detection system, a mobile communication device is owned by a pedestrian, and a pedestrian collision detection device is disposed in a vehicle. A mobile-side impact detection part detects a collision between the vehicle and the pedestrian. A short-distance communication part enables wireless communication within a predetermined range. A vehicle-side collision detection part detects the collision. A wireless communication part enables wireless communication within a predetermined range. The wireless communication part and the short-distance communication part perform mutual authentication through pairing when the vehicle-side collision detection part detects the collision and a result of the detection is held by an impact record part.
