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.

Abstract: A vehicular fuel tank fuel filler orifice device that is provided with a fuel filler orifice in an upper wall of a vehicular fuel tank that stores ethanol fuel for an engine and a fuel filler guide tube extending from the fuel filler orifice to the interior of the fuel tank. A flame arrestor made of a metal mesh with a larger diameter than that of the fuel filler guide tube is mounted on the fuel filler guide tube. The flame arrestor covers a lower opening of the fuel filler guide tube for allowing a flow of the fuel but preventing the entrance of a flame. Using a flame arrestor, not only prevents a flame from entering a fuel tank from a fuel filler orifice but also smoothly carries out an exchange of fuel and air in the flame arrestor when filling with fuel, thus speeding the filling with fuel.
