Abstract
A vehicle system for determining a road wheel angle of a vehicle includes sensors configured to detect vehicle parameters including at least a steering rack load on a steering rack of the vehicle, and a control module in communication with the sensors. The control module is configured to calculate a kingpin torque based on the sensed steering rack load and a wheel-to-body displacement of the vehicle, determine a roll steer angle based on the wheel-to-body displacement of the vehicle, determine a road wheel angle of the vehicle based on the roll steer angle and the kingpin torque, and generate a signal indicative of the road wheel angle to control at least one vehicle control system. Other example vehicle systems and methods for determining a road wheel angle of a vehicle are also disclosed.
