  • Publication number: 20190047468
    Abstract: A driving assistance device for assisting driving a vehicle includes a non-congested state calculation unit and an intent notification control unit. The non-congested state calculation unit is configured to calculate a non-congested state of a plurality of dynamic obstacles around the vehicle. The intent notification control unit is configured to control a notification device such that a notification of intent of the vehicle to pass is performed based on the non-congested state calculated by the non-congested state calculation unit after the vehicle has decelerated or stopped.

  • Publication number: 20190043363
    Abstract: The vehicle external notification device includes a notification unit that gives notice of the information to the outside of the vehicle, a proposal action determination unit that determines an action to be proposed to the pedestrian, a notification control unit that causes the notification unit to notify the pedestrian of information on the action to be proposed to the pedestrian, an action detection unit that detects an action of the pedestrian, and an action determination unit that determines whether or not the action of the pedestrian which is detected by the action detection unit is the action proposed to the pedestrian. The notification control unit causes the notification unit to notify the pedestrian of information indicating that the action of the pedestrian is the proposed action, when the action determination unit determines that the action of the pedestrian is the action proposed to the pedestrian.

  • Patent number: 10045173
    Abstract: Provided is a vehicle outside notification device including a notification necessity determination unit configured to determine whether or not it is necessary to provide a traffic participant in a vicinity of a host vehicle with notification regarding an action schedule of the host vehicle, a preceding vehicle determination unit configured to determine whether or not a preceding vehicle is present in a case where it is determined that it is necessary to provide the notification, a notification output unit configured to output the notification, and a notification control unit configured to control the notification output unit. The notification control unit outputs the notification in a case where the preceding vehicle determination unit determines that the preceding vehicle is not present. The notification control unit restricts the output of the notification in a case where the preceding vehicle determination unit determines that the preceding vehicle is present.

  • Publication number: 20160351688
    Abstract: A method of manufacturing an insulated gate switching device includes: forming a trench in a front surface of a semiconductor substrate; forming a gate insulating film in the trench; depositing an electrode layer made of semiconductor in the trench and on the front surface after forming the gate insulating film; polishing the electrode layer so as to remove a portion of the electrode layer on the front surface and expose an underlayer of the removed portion of the electrode layer; forming a cap insulating film in a surface layer of a portion of the electrode layer in the trench by heating the semiconductor substrate after exposing the underlayer; and implanting impurities from above the front surface into a range extending across the portion of the electrode layer in the trench and the semiconductor substrate.
