Abstract:
In a transportation/logistics system in which a pallet/vehicle with an automobile/container mounted/fixed thereon travels, a normal steering operation is carried out by changing the direction of the wheels (including tires) by an electronically controlled automatic steering system on the basis of steering information, whereby comfortable travel and a smooth turns are obtained. When the pallet/vehicle is about to run off a lane on which it travels, the run-off thereof is prevented physically and mechanically since a fin provided on the pallet/vehicle is inserted in a groove provided in a road, whereby a safe traffic/transportation system is obtained. The pallet/vehicle obtains a driving force by a gap length regulated/controlled linear induction motor so that the pallet/vehicle can travel at high speeds. In diverging (branching) and merging (converging) points, the diverging (branching)/merging (converging) of the pallet/vehicles is practiced by steering the wheels (tires) by the automatic steering system, and the pallet/vehicle advances with the fin inserted in a groove in a main line or a ramp, whereby a reliable, safe traffic/transportation system adapted to practice high-speed diverging (branching) is obtained. At the exit/entrance of the present invention to/from a general road, a mode interchange is provided which is adapted to convert a traveling mode of an automobile/container, and mounts and fixes an automobile/container on the pallet/vehicle and unfastens such automobile/container.
Abstract:
An automatic steering system which reduces formation of a wheel track by changing a relative position of a vehicle with respect to a road. A reference line is provided along a road so that a vehicle moves along the reference line. The vehicle moves on the road while an amount of shift from the reference line is controlled to be equal to a target amount of shift. The amount of shift is a distance between a predetermined position of the vehicle and the reference line. A moving line of the vehicle is fluctuated with respect to time in a direction substantially perpendicular to an extending direction of the reference line. Alternatively, the reference line may be shifted in a direction substantially perpendicular to the extending direction of the reference line.
Abstract:
A lane sensing system (20) comprises a processor (22) operable to drive an infrared optical transmitter (24). Light is reflected by a center stripe (18) placed in the center of a highway lane. Reflected light is received in right and left receivers (26) and (28). The processor (22) uses the information to control a power steering control system (30) and a speed control system (32). Information may be encrypted into the center stripe (18) and used by processor (22) to control the speed of the vehicle (10) or to display information to an operator of the vehicle (10) through a display system (34).

Abstract:
A driver assistance apparatus for a vehicle includes a camera configured to photograph an image of surroundings of a vehicle; an interface; and a processor. The processor is configured to detect, based on the image photographed by the camera, a lane in which the vehicle travels; acquire braking state information of the vehicle; and provide, to a steering apparatus, a signal for steering the vehicle or provide, to a brake apparatus, a signal for one-sided braking through the interface to maintain the vehicle within the lane in which the vehicle travels during a braking of the vehicle based on the acquired braking state information.
