  • Publication number: 20250149926
    Abstract: A contactless power feeding apparatus includes a plurality of primary coils mounted on a road and a power feed controller which uses a portion of the primary coils as a power transmitting coil to achieve delivery of electrical power from the power transmitting coil to a secondary coil mounted in a vehicle. The power feed controller uses a selected primary coil that is one of the primary coils other than the power transmitting coil to decrease a leakage of magnetic flux arising from excitation of the power transmitting coil. Instead of the selected primary coil, the secondary coil may be used to reduce the leakage of magnetic flux.

  • Publication number: 20250146823
    Abstract: An arrival time determining device that can accurately estimate a timing of arrival at a predetermined position. A mobile terminal 100 includes at least a user motion determining unit 102, an estimated arrival time calculating unit 104, and an arrival time determining unit 105. The user motion determining unit 102 determines a user motion (a stopped state or a boarding state) based on motion sensor information of the mobile terminal 100. The estimated arrival time calculating unit 104 calculates a time (time A) at which the mobile terminal 100 has arrived at a destination as an estimated arrival time test based on a position of the mobile terminal 100 and the user motion (when the user is in the stopped state). The arrival time determining unit 105 determines the estimated arrival time test as a result arrival time tres based on the user motion (when the user is in the boarding state). The result arrival time tres is used to next calculate the estimated arrival time test.

  • Publication number: 20240371173
    Abstract: To realize a configuration of analyzing a captured image captured by a monocular camera and determining whether an object in the captured image is a real object or a drawing object. An image captured by a monocular camera mounted on a vehicle is analyzed to determine whether an object in the captured image is a real object or a drawing object. An image signal analysis unit determines that an object in the captured image is a drawing object in a case where a change amount per unit time of a FOE (focus of expansion) position in the captured image is equal to or larger than a predetermined threshold value, in a case where a change amount per unit time of a lane width detected from the captured image is equal to or larger than a predetermined threshold value, or in a case where a difference between a grounding position of a vehicle or the like in the captured image and a ground level position corresponding to the vehicle grounding position is equal to or larger than a predetermined threshold value.
