  • Publication number: 20240123979
    Abstract: An automatic brake control apparatus to be applied to a vehicle is configured to: detect, with an ultrasonic sensor, a position of an obstacle on reverse travel of the vehicle, in which the ultrasonic sensor is disposed in a rear part of the vehicle; set a brake operation area on plane coordinates corresponding to the detected position by the ultrasonic sensor; and actuate an automatic brake. The brake operation area includes a low-speed operation area and a high-speed operation area. The low-speed operation area is set on the reverse travel at a lower speed than a setting vehicle speed, and the high-speed operation area is set on the reverse travel at a higher speed than the setting vehicle speed. The high-speed operation area is wider than the low-speed operation area at least in a vehicle widthwise direction.

  • Publication number: 20160036600
    Abstract: A gateway device includes an address manager that manages address information enabling transmission via a second interface of an own gateway device and another gateway device, a first relay that, if the data received by the second interface is multicast data, adds to the multicast data received, address information and a header conforming to a protocol of a non-band-sharing network, and outputs the multicast data to a first interface, and a second relay that, if the data received by the first interface includes address information, extracts only multicast data from data conforming to the protocol of the non-band-sharing network, and transmits the multicast data to the second interface. Even when collision domain for N (N is 2 or more) of facility networks having different address architectures is to be divided using (N+1) or more of gateways, multicast communication that match the area of the address architecture can be realized.
