  • 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: 20220274150
    Abstract: A method for manufacturing a press-formed product suppresses occurrence of a forming defect such as a crack in a starting material during press forming, and also suppresses occurrence of problems when transferring a starting material during press forming. A manufacturing intermediate is formed by forming, in a flat-sheet shaped blank sheet, a planned outline portion including an undulating shape which is used for forming an outline of an outer circumferential portion of a press-formed product. The flat shape of the blank sheet is maintained in a region from the planned outline portion toward the center of the manufacturing intermediate, or an intermediate stretch-formed portion having a predetermined intermediate forming height is formed in the manufacturing intermediate in the region. A through-hole is formed by piercing a flat portion at which the flat shape is maintained or a stretch-formed-side top portion of the intermediate stretch-formed portion.
