Electric power steering control methods and systems using hysteresis compensation

摘要

A control system (40) for a steering system (12) is provided. The control system (40) includes a direction determination module (52), a position determination module (54), and a final command module (58). The direction determination module (52) determines a change in a handwheel torque. The position determination module (54) determines a position on a hysteresis loop. The position on the hysteresis loop depends on the change in the handwheel torque. The final command module (58) determines a final assist value based on the position. The final command module (58) generates an assist command.
