Vehicle steering system control

摘要

A system (10) and method for controlling a steer-by-wire steering system. The system (10) has a steering wheel control subsystem (12) that provides steering feel for the operator, a reference angle (40) to the road wheels and tracks the road wheel angle. A road wheel control subsystem (14) tracks a steering wheel angle and produces a steering wheel reference angle (32) and torque signal (34) to the steering wheel control subsystem (12). The system and method of the present invention implements the same steering requirements for a steer-by-wire steering system as a conventional steering system and can implement advanced and flexible steering functions that cannot be accomplished with a conventional steering system.
