Abstract
The present invention involves a method and system of initial aligning wheels of vehicle steer-by-wire systems with two independent front road wheels in the real time. The method comprises providing a steering wheel control sub-system and a road wheel control sub-system, providing an initial alignment unit and procedure to align the road wheels and steering wheel, and receiving relative and absolute steering wheel angles and road wheel angles. The method further includes generating wheel aligning reference angles based on the relative and absolute wheel angle, generating the switch control signal based wheel aligning reference angles using the logic operation with the threshold, and determining the steer-by-wire systems in the control state or in the initial alignment state.
