ABSTRACT:
A steering system and method are capable of steering a plurality of vehicles arranged in a train with adjacent vehicles pivotally connected to each other for movement about a vertical axis. Each vehicle has a pair of steerable wheels with one pair at one end of the train being a selected leading pair having its steering angle determined by an operator. An electrical control system automatically steers all of the wheels trailing behind the leading pair. Vehicle angle sensors measure intercar angles between adjacent vehicles and provide this information to the control system. An indicator provides the controller with the current distance traveled by the train. Wheel angle sensors provide signals indicative of the current steering angle for each wheel pair. The controller adjusts the actual steering angle for each trailing pair to a desired angle by calculating adjustments based on the measurement inputs.
