  • Patent number: 11827042
    Abstract: A tag writing device includes a conveying unit, an antenna, an acquiring unit, a determining unit, a selecting unit, and a deciding unit. The acquiring unit acquires reception intensities about a plurality of wireless tags. The determining unit determines an intermediate position between a start position and an end position as a position where a sum of reception intensities acquired while a mount is conveyed from the start position to the intermediate position and a sum of reception intensities acquired while the mount is conveyed from the intermediate position to the end position are closest. The selecting unit selects, as a target tag, the wireless tag, the intermediate position of which is determined as a position within a prediction range. The deciding unit decides a relative positional relation between the wireless tag and the antenna at a time when writing is performed.

  • Publication number: 20230068472
    Abstract: The driving assistance apparatus comprises a camera device configured to obtain a camera image by taking a picture of a predetermined area ahead of a host vehicle; and a control unit configured to drive the host vehicle so as to cause an acceleration of the host vehicle to become equal to a follow-up acceleration to make an inter vehicle distance to a preceding vehicle coincide with a target inter vehicle distance. When the preceding vehicle is a large-size vehicle, the control unit obtains the target inter vehicle distance for causing a traffic-signal-equipment-distance indicative of a distance to a traffic signal equipment of when the traffic signal equipment is detected above the preceding vehicle in the camera image to be longer than a stop-required-distance for which the host vehicle travels until the host vehicle stops under the assumption that the host vehicle decelerates at a predetermined deceleration.
