  • Patent number: 6368042
    Abstract: A conveyor conveys palletized articles to a loading dock. A bogie movable along rails between different loading docks, supports an independently movable carriage, which may roll out of the bogie once the latter reaches a desired loading dock. The carriage then loads with a forklift provided on the carriage, the articles from the conveyor into a semi-trailer located at the loading dock. The carriage is provided with a linkage pivotally installed on its main frame, the linkage carrying four lateral guide wheels which protrude laterally beyond all other structural elements of the carriage. The linkage integrally links the guide wheels into a common pivotal displacement, with the guide wheels remaining symmetrically disposed relative to the carriage frame. A hydraulic piston biases the guide wheels towards an outer limit position at all times, and the guide wheels are forcibly pivotable, against the bias of the piston, towards an inner limit position.

    Abstract: A guideway transit system which can reduce a scale of an infrastructure while maintaining ride comfort for passengers of a vehicle is provided. The guideway transit system includes a noncontact vehicle guiding system and a contact vehicle guiding system. The noncontact vehicle guiding system detects information relating to a lateral position of a vehicle on a road and steers the vehicle to move along a predetermined path on the road based on the detected information. The contact vehicle guiding system which restricts a lateral position of the vehicle by a contact between a guide wheel which laterally projects from the vehicle and a guide wall provided on a side of the road. The guideway transit system further includes a controller which prohibits steering of the vehicle by the noncontact vehicle guiding system when a lateral position of the vehicle is restricted by the contact vehicle guiding system. An automated vehicle which is used in the guideway transit system is also provided.

  • Patent number: 6186259
    Abstract: An automatic steering device for a vehicle is provided to prevent an automatically steered vehicle from going out of its predetermined locus of movement as a result of an abnormal output of a movement distance detecting device. An actuator control device controls a steering actuator based upon the distance of movement detected by the movement distance detecting device and upon a locus of movement of the vehicle stored in a storage device. A judging device compares a vehicle speed estimated by a vehicle speed estimating device with an actual vehicle speed calculated by an actual vehicle speed detecting device from the distance of movement based upon the operating condition (shift range, accelerator opening degree and brake operating amount) of the vehicle detected by an operating condition detecting device.

  • Patent number: 6148943
    Abstract: A system for controlling behavior of a vehicle having a laser radar for detecting an obstacle present on a road on which the vehicle is traveling and operating the brake automatically to avoid contact with the obstacle, and having a power-assist steering actuator including an electric motor installed in the steering system. In the system, it is determined whether the vehicle is steered by the steering wheel as manipulated by the vehicle operator or the vehicle is steered by a force generated by the interplay between the tire and road due to the automatic braking and, when vehicle is steered by the force generated by the tire/road interplay, the electric motor of the steering actuator is controlled to drive in the direction to cancel the force, thereby preventing the vehicle behavior from degrading to deviate from the desired course of travel and preventing various disadvantages such as failure to achieve the desired obstacle detection necessary for an effective obstacle avoidance control.
