Abstract
A disclosed method can control an electric motor for an electromechanical power steering mechanism for assisting steering for a motor vehicle. The electromechanical power steering mechanism may include a steering column with an upper steering shaft linked to a lower steering shaft by a torsion bar. A torsion angle between the upper steering shaft and the lower steering shaft is configured to be measured or estimated, and an electric motor is configured to apply an assistance torque. The method may involve calculating a desired rotor position with an assist algorithm based on the torsion angle and calculating a PWM pattern by a PWM control unit such that the calculated PWM pattern adjusts a rotor of an electric motor angle such that the torsion angle is decreased.
