Abstract:

An controller uses one of several transfer curves to map steering angle of an articulated machine to articulation angle. Because an articulated machine may have a range of steering angles that is much greater than the range of articulation angles, the controller uses one of several techniques to map the full range of steering angles to the full range of articulation angles. One technique involves multiple non-zero slope regions, another technique uses a less than one-to-one linear transfer function of steering angle to articulation angle.
