Publication number: 20240241209Abstract: A vehicle control device is provided which has enhanced robustness against a shielding object, further, which does not measure a received radio wave from a radio transmitter and which can continue, for example, automatic driving control by comparing two types of vehicle positions calculated using the radio transmitter installed outside a vehicle and a sensor mounted on the vehicle and detecting an error in order to reduce a detection error of the radio transmitter due to a failure in communication of the radio transmitter. Two types of vehicle positions calculated using the sensor mounted on the vehicle and the radio transmitter are compared, and it is determined that the radio transmitter is affected by a shielding object in a case where a temporal change of a vehicle position deviation and/or a behavior change of a vehicle position (first own vehicle position) based on the radio transmitter is detected.Type: ApplicationFiled: March 8, 2022Publication date: July 18, 2024Applicant: HITACHI ASTEMO, LTD.Inventors: Yuta TSURUMOTO, Keisuke TAKEUCHI, Seiya ISHII

Publication number: 20240174230Abstract: An object of the present invention is to provide a vehicle control device capable of improving ride comfort of a driver. A lane change detection unit 205 of a vehicle control device 200 determines a possibility of cut-in of an adjacent vehicle immediately in front of an own vehicle on the basis of an adjacent vehicle relationship value (for example, a relative speed between the own vehicle and the adjacent vehicle) in an advancing direction. An acceleration/deceleration control unit 206 corrects acceleration/deceleration of the own vehicle on the basis of the possibility of the cut-in determined on the basis of the adjacent vehicle relationship value in the advancing direction.Type: ApplicationFiled: February 28, 2022Publication date: May 30, 2024Applicant: HITACHI ASTEMO, LTD.Inventors: Takayuki SAITO, Masashi SEIMIYA, Taku TAKAHAMA, Keisuke TAKEUCHI, Yuta TSURUMOTO, Seiya ISHII

Patent number: 10981601Abstract: In an impact-absorbing member which extends in a vehicle length direction of an automobile and whose both end portions in the vehicle length direction have a collision-side end portion and a non-collision-side end portion whose positions become mutually different when seen from the vehicle length direction, an outer member and an inner member of the impact-absorbing member are formed so that a position of a gravity center at the collision-side end portion and a position of a gravity center at the non-collision-side end portion become mutually different according to a positional relationship between the collision-side end portion and the non-collision-side end portion in order to suppress a tensile stress generated at the collision-side end portion and suppress a compressive stress generated at the non-collision-side end portion in a collision.Type: GrantFiled: March 31, 2017Date of Patent: April 20, 2021Assignee: NIPPON STEEL CORPORATIONInventors: Yutaka Mikazuki, Eiji Isogai, Seiya Ishii

Patent number: 10427633Abstract: [Object] To improve load resistance performance in response to collision. [Solution] An end structure of a vehicle according to the present invention includes: a beam 2 that extends in a vehicle width direction; and a connecting structure 3 that connects the beam 2 to a vehicle body frame. In a cross-sectional view perpendicular to the vehicle width direction, the beam 2 includes a first top surface part 2a and a first bottom surface part 2b which face each other, a first side surface part 2c that connects one ends of the first top surface part 2a and the first bottom surface part 2b, and first flange parts 2d that are formed to protrude vertically outwardly at the other ends of the first top surface part 2a and the first bottom surface part 2b.Type: GrantFiled: February 1, 2016Date of Patent: October 1, 2019Assignee: NIPPON STEEL CORPORATIONInventors: Yutaka Mikazuki, Eiji Isogai, Kenji Yamamoto, Takashi Ariga, Seiya Ishii

Publication number: 20170333972Abstract: A producing method of the press formed product includes a preparation step of preparing a metal sheet as a starting material, and a press working step of performing press working on the starting material by using a punch, and a pad and a die that are paired with the punch. The press working step includes a first step of forming, by the punch and the pad, the entire region of a top panel part, the entire region of each of a ridge line parts including the shape-changing part, and a region up to a predetermined height from the border between a vertical wall part and the ridge line part of a region of each of the vertical wall parts, and a second step of forming, subsequent to the first step, by the punch and the die, the remaining regions with the starting material sandwiched between the punch and the pad.Type: ApplicationFiled: November 11, 2015Publication date: November 23, 2017Inventors: Ryuichi NISHIMURA, Yoshiaki NAKAZAWA, Toru YONEBAYASHI, Seiya ISHII, Koichi SATO
