Patent number: 11912272Abstract: In a target track generation apparatus, a subject vehicle reference preceding vehicle position calculator calculates a point group of subject vehicle reference preceding vehicle positions representing a history of a relative position of a preceding vehicle in a coordinate system using a current position of a subject vehicle as a reference. A target track generator generates a target track of the subject vehicle, based on the point group of the subject vehicle reference preceding vehicle positions. A correction target track generator generates a correction target track obtained by correcting the target track, based on the point group of the subject vehicle reference preceding vehicle positions or the target track, when it is determined that correction of the target track is necessary.Type: GrantFiled: October 30, 2018Date of Patent: February 27, 2024Assignee: Mitsubishi Electric CorporationInventors: Rei Yoshino, Masaya Endo, Yasuyoshi Hori, Tetsuharu Hamada, Takahiro Urabe

Publication number: 20210394755Abstract: In a target track generation apparatus (10), a preceding vehicle position acquisition unit (1) acquires a relative position of a preceding vehicle. A subject vehicle state quantity acquisition unit (2) acquires a state quantity of a subject vehicle. A subject vehicle movement amount calculator (3) calculates a movement amount of the subject vehicle, based on the state quantity of the subject vehicle. A subject vehicle reference preceding vehicle position calculator (4) calculates a point group of subject vehicle reference preceding vehicle positions representing a history of the relative position of the preceding vehicle in a coordinate system using a current position of the subject vehicle as a reference, based on the relative position of the preceding vehicle and the movement amount of the subject vehicle. A target track generator (5) generates a target track of the subject vehicle, based on the point group of the subject vehicle reference preceding vehicle positions.Type: ApplicationFiled: October 30, 2018Publication date: December 23, 2021Applicant: Mitsubishi Electric CorporationInventors: Rei YOSHINO, Masaya ENDO, Yasuyoshi HORI, Tetsuharu HAMADA, Takahiro URABE

Patent number: 11175661Abstract: In the vehicle traveling control device, a host vehicle location specification unit specifies a host vehicle location on a map. A first peripheral information detector detects a location of a planimetric feature or characteristics of a road in a periphery of the host vehicle on the basis of map data and the host vehicle location on the map specified by the host vehicle location specification unit. A second peripheral information detector detects a location of a planimetric feature or characteristics of a road in the periphery of the host vehicle on the basis of information acquired by a camera, a sensor, or a road-vehicle communication device mounted on the host vehicle. When the detection result from the first peripheral information detector and the detection result from the second peripheral information detector do not coincide, an automatic driving restriction unit restricts performance of automatic driving of the host vehicle.Type: GrantFiled: April 18, 2017Date of Patent: November 16, 2021Assignee: Mitsubishi Electric CorporationInventors: Toshihide Satake, Kazuo Hitosugi, Takahiro Urabe

Patent number: 10077072Abstract: Provided are a vehicle steering device and the like, which are capable of converging a lateral displacement at a forward gazing-point distance to a target travel line with simple control. A target travel line for a vehicle to travel by following a travel path recognized from an image taken by a camera or the like is set. A lateral speed, which is a change amount of the lateral displacement that is a difference between a position of the target travel line at the forward gazing-point distance and a position of the vehicle, is controlled so that the lateral displacement is reduced. A target steering angle is calculated based on the lateral speed, and a steering angle of the vehicle is controlled based on the calculated target steering angle.Type: GrantFiled: September 16, 2015Date of Patent: September 18, 2018Assignee: Mitsubishi Electric CorporationInventors: Yasuyoshi Hori, Yukiyasu Akemi, Masaya Endo, Hideyuki Tanaka, Takayuki Tanaka, Takahiro Urabe, Kouhei Mori
