Abstract
A vehicle system includes a road wheel system having a road wheel actuator and at least one pinion angle sensor, and a control module. The control module is configured to receive a road wheel actuator command and a rack force, generate a model of the road wheel system based on the road wheel actuator command and the rack force, estimate, with a state observer, a steering pinion angle based on the generated model, the road wheel actuator command and the rack force, determine a validity of a steering pinion angle measured by the at least one pinion angle sensor based on the estimated steering pinion angle and a threshold, and in response to determining that the measured steering pinion angle is invalid, control a steering function of the vehicle based on the estimated steering pinion angle.
