Publication number: 20250136146Abstract: This automated driving system includes a vehicle having a target traveling path for performing automated traveling, the automated driving system being configured to acquire a position and an azimuth of the vehicle and a measurement reliability therefor. The vehicle includes an automated traveling restart determination unit for switching from a stopped state to automated traveling. In a case where the measurement reliability is equal to or greater than a predetermined first threshold, restart of automated traveling of the vehicle is permitted when an absolute value of a first position deviation between the target traveling path and the position of the vehicle is equal to or smaller than a predetermined second threshold and an absolute value of an angle deviation between an azimuth of the target traveling path and the azimuth of the vehicle is equal to or smaller than a predetermined third threshold.Type: ApplicationFiled: August 27, 2024Publication date: May 1, 2025Applicant: Mitsubishi Electric CorporationInventors: Michitoshi AZUMA, Toru Higuchi, Takayuki Tanaka, Kohei Mori

Publication number: 20240157975Abstract: An autonomous driving integrated control system includes multiple roadside monitoring devices and an autonomous driving device, wherein the multiple roadside monitoring devices each have a sensor and a transmitter that transmits information of a detected object, and wherein the autonomous driving device has: a receiver unit; a vehicle abnormal state detection unit; an escape route generation unit that generates, per each of the roadside monitoring devices, intersection escape routes for escaping from the intersection; a selection unit that compares the thus-generated intersection escape routes with each other in terms of their collision-avoidance levels, to thereby make selections; a travelable distance calculation unit that calculates an abnormal-time travelable distance; a vehicle control unit that, when an abnormal state of the vehicle is detected, causes the vehicle to travel along a high-level intersection escape route corresponding to the abnormal-time travelable distance; and a vehicle operation unit.Type: ApplicationFiled: August 28, 2023Publication date: May 16, 2024Applicant: Mitsubishi Electric CorporationInventors: Michitoshi AZUMA, Kohei MORI, Toru HIGUCHI, Hiroshi YAMADA

Publication number: 20230128212Abstract: An apparatus is obtained which provides, to a vehicle, information on a road-surface and that on an obstacle(s), and information on the degree of reliability, on the basis of information received from roadside units. The apparatus includes a communications circuitry to receive obstacle information from the roadside units where each unit includes a plurality of sensors to detect the obstacle(s) within a predetermined field of view. A reliability determinator determines the degree of reliability of information on an obstacle(s) received, and outputs a reliability value on the bases of the number of roadside units detecting the same obstacle, the number of sensors in one roadside unit detecting the same obstacle, and a difference value of detecting the same obstacle between different roadside units or that of detecting the same obstacle between different sensors; and a correction term is outputted on the basis of information on a road-surface condition.Type: ApplicationFiled: August 29, 2022Publication date: April 27, 2023Applicant: Mitsubishi Electric CorporationInventors: Michitoshi AZUMA, Toru Higuchi, Takatoshi Kakuta, Toshihide Satake, Fumiaki Kadoya, Takahisa Aoyagi
