Abstract
A steering system for an industrial vehicle includes a drive wheel configured to steerably align with a first radius of curvature. The steering system further includes an electronically controlled idler wheel configured to steerably align with a second radius of curvature different than the first radius of curvature. The first and second radii of curvature share a common center point of turning radius. A controller is configured to command the electronically controlled idler wheel to steerably align with the second radius of curvature according to a determination of the first radius of curvature.
