Steering system for an articulating vehicle

Abstract

A steering assist system operably engaged with an articulating tractor at a pivot point. The steering assist system includes a controller, a sensor unit operably engaged at the pivot point of an articulating chassis of the articulating tractor, a steering actuator operably engaged with a front articulating frame of the articulating chassis and a rear articulating frame of the articulating chassis to pivot the articulating chassis at the pivot point based on at least one output from the controller, and a steering unit operable with the controller to input one or more steering commands to steer the articulating tractor. The sensor unit of the steering assist system is configured to measure rotation of the articulating chassis about a vertical axis of the articulating tractor at the pivot point.
