  • Patent number: 11963090
    Abstract: A communication control device used in a terminal device that performs mobile communication is provided. The communication control device controls a communication module of the terminal device to perform direct communication with a different terminal device not via a base station. The communication control device manages whether the communication module is in a search mode or a communication mode, and determines, using information managed, whether a transmission timing of a signal from the communication module determined in accordance with occurrence timing of a transmission event overlaps the search mode. When determining that the transmission timing overlaps the search mode, the communication control device shifts the transmission timing out of the time duration of the search mode.

  • Patent number: 11959752
    Abstract: A lateral position of a vehicle is estimated by collating a position of a lane division line in map data with a relative position of the lane division line with respect to the vehicle indicated by a recognition result by a peripheral monitoring sensor. The lateral position of the vehicle is precluded from being specified using the estimated lateral position of the vehicle in response to a lateral deviation between (i) a position of a landmark in the map data and (ii) a translated landmark position being equal to or greater than a first threshold value. The translated landmark position is a position on map deviated from the estimated lateral position of the vehicle assumed to be the lateral position of the vehicle on map by a relative position of the landmark with respect to the vehicle indicated by the recognition result by the peripheral monitoring sensor.
