Patent number: 10559205Abstract: A setting unit of an object existence determination apparatus sets an object-existence determination region with a lateral width in the travelling direction of an own vehicle using a lateral speed of a target object and a determination result by a straight-travel determining unit. An existence determining unit determines, based on the lateral position of the target object and the object-existence determination region, whether there is a possibility of at least part of the target object existing on a travelling course of the own vehicle. The setting unit sets the lateral width of the object existence determination region to be larger as the lateral speed becomes higher, and sets, upon determination that the own vehicle is not travelling straight, the lateral width of the object existence determination region to be smaller than the lateral width of the object-existence determination region used when the own vehicle is travelling straight.Type: GrantFiled: March 31, 2016Date of Patent: February 11, 2020Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akitoshi Minemura, Yosuke Ito, Jun Tsuchida, Hitoshi Yuasa

Patent number: 8307935Abstract: In a vehicle pop-up hood apparatus in which a rod is extended and a hood is pushed up by the operation of an actuator at a time of collision with a collision body, collision energy is absorbed with high efficiency when a collision load of a predetermined value or greater is input to an area near a hood pushed up position. Actuator (18) operates such that rod (20) moves in an axial direction toward a hood upper side, pushes up a rear edge side of hood rocker (12) and holds it at that position and, in that state, when a collision load of a predetermined value or greater acts from a hood upper side to near the pushed up position of the hood, push portion (54) slides along pushed up surface (38) of hinge arm (30) towards a vehicle rear side, and rod (20) is made to bend in conjunction therewith.Type: GrantFiled: January 22, 2009Date of Patent: November 13, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, Toyoda Gosei Co., Ltd., Pacific Industrial Co., Ltd.Inventors: Hiroyuki Takahashi, Hitoshi Yuasa, Yukio Nakagawa, Kazuyuki Yoshiyama, Shigeyuki Suzuki, Takeki Hayashi, Hajime Kitte, Masashi Aoki, Toshikatsu Togawa, Toshinobu Tsuboi, Shinji Mori

Patent number: 7975797Abstract: In a configuration in which a rod is extended by an actuator and raises a hood at a time of a collision with a collision body, when a collision load greater than a predetermined value is input to near a hood pushed up area, the collision energy is efficiently absorbed. In a state in which a hood (12) is maintained in a pushed up position, when a collision load equal to or greater than a predetermined value is input from a hood upper side, a distal end portion (54) of a rod (20) slides towards a vehicle rear side along a pushed up surface (38) of a hood rear portion, while deforming the rod (20) by bending, thereby absorbing collision energy. At this time, before a base of a hinge arm (30) contacts a cowl top side (22), distal end portion (54) of rod (20) catches against a bending portion (60) such that rod (20) is bent further.Type: GrantFiled: January 23, 2009Date of Patent: July 12, 2011Assignees: Toyota Jidosha Kabushiki Kaisha, Pacific Industrial Co., Ltd.Inventors: Hitoshi Yuasa, Hiroyuki Takahashi, Hajime Kitte, Masashi Aoki, Toshikatsu Togawa, Toshinobu Tsuboi
