Patent number: 8245648Abstract: A guided vehicle transportation system is described in the application. The system includes guard wheels and a guard rail positioned along a center line of a guide track. The guard rail has a groove in which the guard wheels are received with a predetermined clearance between the periphery of the guard wheels and side walls of the groove. The guard rail has a flange extending toward the groove at the top of each side wall. The vehicle has first arms extending in longitudinal direction and being attached rotatably at a central part of an axle provided for suspending each pair of front wheels and rear wheels, and the guard wheels are attached rotatably and directly to the both end parts of the first arms or attached rotatably to both end parts of second arms each of which is attached to a corresponding end part of the first arms.Type: GrantFiled: October 31, 2007Date of Patent: August 21, 2012Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Shunji Morichika, Katsuaki Morita, Masahiro Yamaguchi, Kosuke Katahira, Yasuhiro Nagamichi

Patent number: 8209091Abstract: According to a steering control method, before starting, a pattern steering angle table on which pattern steering angles for the front and rear wheels at respective change points of the track are listed is prepared in view of a track condition, etc. from a departure point to a destination point, a vehicle is steered in accordance with a pattern steering angle read from the table, a track widthwise position of the vehicle on running is detected so as to calculate correcting steering angles by which the track widthwise position of the vehicle coincides with a desired position, and the correcting steering angles are added to pattern steering angles so as to obtain desired steering angles by which the front wheels are steered. The pattern steering angle, the corrected steering angle and the desired steering angle are calculated for each of the front and rear wheels, independent from each other.Type: GrantFiled: January 21, 2008Date of Patent: June 26, 2012Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Shunji Morichika, Katsuaki Morita, Masahiro Yamaguchi, Mitsuaki Hoshi, Kousuke Katahira
