摘要： An articulated work machine determines the relative orientation of two members of the machine utilizing output from inertia sensors mounted on the members. The machine includes a first frame and a second frame having a body and a chassis, the body pivotally connected to the chassis at a pivot point. The first and second frames are connected by a coupling and are movable relative to each other in at least one direction. The machine includes a first multi-axis inertia sensor attached to the first frame providing an output relating to the position of the first frame, and a second multi-axis inertia sensor attached to the body providing an output relating to the position of the body. The machine further includes a controller configured to compare the outputs of the first and second multi-axis inertia sensors to calculate the position of the body and the first frame relative to each other.
