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

Publication number: 20210347359Abstract: A lane information detection unit detects the shape and the road width of a traveling lane of a vehicle. A present transverse position detection unit detects a present transverse position indicating a present traveling position of the vehicle in the width direction of the traveling lane. A driver-corresponding transverse position setting unit sets a driver-corresponding transverse position corresponding to a driving tendency of a driver. An upper/lower limit value setting unit sets upper/lower limit values that the driver-corresponding transverse position can take, in accordance with the road width. Then, when change in the road width is detected, a transverse position control amount calculation unit sets, as a target transverse position, the driver-corresponding transverse position within the upper/lower limit values in which the change is reflected, and calculates a transverse position control amount for the vehicle from the present transverse position of the vehicle.Type: ApplicationFiled: March 4, 2019Publication date: November 11, 2021Applicant: Mitsubishi Electric CorporationInventors: Shuuhei NAKATSUJI, Yu TAKEUCHI, Kazuo HITOSUGI, Fumiaki KADOYA, Kazushi MAEDA
