Abstract:
Methods and systems for analyzing and/or calibrating an adaptive steering system are disclosed. One method may include rotating a hub that is configured to engage a steering shaft over a predetermined range of hub angles using a gear and an internal electric motor in response to a control signal. A torque required to rotate the hub as a function of the hub angles may be determined, as well as whether the torque is within a predefined torque window. The method may be used to analyze the overall friction in the adaptive steering wheel assembly. In one embodiment, the method may be performed with the steering wheel assembly fully assembled and the internal electric motor covered and inaccessible. The torque may be determined by calculating the torque based on a current draw of the internal electric motor.
