Abstract
A steering system for an articulated steered mobile work machine has a first sensor for sensing the relative angular position of first and second machine sections and a second sensor for sensing the relative angular position of second and a third machine sections. A controller determines for a sensed relative angle of the first and second machine sections the desired relative steering angle of the second and third sections and actuates a second control valve to direct fluid flow to a second pair of fluid operated jacks and pivot the third machine section to a desired angular position relative to the second machine section. The second sensor provides feedback as to the relative angular position of the second and third machine sections.
