A STEERING ARRANGEMENT FOR A VEHICLE WHICH IS MOVABLE ALONG A PREDEFINED PATH IN USE, BEING AUTOMATICALLY STEERED VIA AT LEAST ONE FIRST AXLE, AS WELL AS A VEHICLE PROVIDED WITH SUCH A STEERING ARRANGEMENT

摘要

The invention relates to a steering arrangement for a vehicle which is movable along a predefined path in use, being automatically steered via at least one first axle. The invention also relates to a vehicle provided with such a steering arrangement. The invention further relates to a method for moving a vehicle that is automatically steered via at least one first axle by a steering device along a predefined path. It is an object of the invention to provide a steering arrangement as described in the introduction for use in an automatically guided and steered vehicle, i.e. without a driver, which steering arrangement can continue to influence the steerage of the vehicle for a minimum period of time in case of a malfunction, such that the risk of dangerous situations or accidents is minimised. In order to accomplish that object, the steering arrangement according to the invention comprises: a path tracking system comprising information characteristics relating to the predefined path to be followed; path sensor means designed to detect a deviation from the predefined path by the vehicle; steering means designed to steer the at least first axle so as to correct the detected deviation from the path, which steering means comprise at least three drivelines, which drivelines control said at least first axle independently of each other.
