Abstract
The present invention involves a method of controlling a vehicle steer-by-wire system having two independent road wheels. In one embodiment, the method comprises providing a steering wheel control sub-system to generate road wheel reference angles and to produce steering feel for a vehicle driver. The method further includes providing a road wheel control sub-system with a servo control system structure including a multivariable road wheel controlled plant and a multivariable road wheel controller for controlling actual road wheel angles to track to road wheel reference angles. The method further includes generating left and right road wheel reference angles from the steering wheel angle with a road wheel reference angle generator using variable left and right steering ratios and calibration processes based on calibration variables, wherein the road wheel reference angle generator has first and second stages to produce left and right road wheel reference angle outputs. The present invention also involves a system for controlling a vehicle steer-by-wire system having a road wheel reference generator.
