摘要： A method for passive damping in a steer-by-wire handwheel actuator includes selecting a number of windings for a motor of a handwheel actuator; shorting a subset of windings of the number of windings, each winding of the subset of windings being disposed at an obtuse angle from each other winding of the subset of windings; determining a resistance value for the motor; selectively adjusting the resistance value based on a number of windings associated with the subset of windings; and providing, in series with the subset of windings, at least one metal-oxide-semiconductor field-effect transistor (MOSFET) configured to: vary the resistance associated with the subset of windings based on a vehicle speed; and tune a damping characteristic associated with the handwheel actuator.
