Abstract
Systems and methods for determining an absolute rotational position of the vehicle handwheel are provided. In one exemplary embodiment, a method includes determining a slope value based on the delta torque value associated with the vehicle steering system and the delta rotational position value associated with a vehicle handwheel. The method further includes setting an absolute position value indicating the absolute position of the vehicle handwheel equal to a predetermined steering travel limit of the vehicle handwheel when the slope value is within a predetermined slope range.
