Adjustable steering limit

摘要

A steering system for a vehicle includes at least one wheel that pivots to define a steering angle, and a steering lock that limits an input to the steering angle from an operator to a selected maximum value. The steering system also includes a motor operatively connected to the wheel that augments the input to the steering angle from the operator, and a controller operatively connected to the motor and adjusting the augmentation of the input to the steering to provide a maximum angle from the operator based upon at least one operating parameter, that may include the size of the wheel or wheel travel, thereby allowing the wheel to pivot to a steering angle based on the operating parameter that exceeds the steering angle corresponding to the maximum allowable value as defined by the operator input.
