Systems and methods for distributed winding passive damping in a steer by wire handwheel actuator

A system for passive damping in a handwheel actuator, the system comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor, cause the processor to:
• select a number of windings for a motor of a handwheel actuator;
• short 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;
• determine a resistance value for the motor;
• selectively adjust the resistance value based on a number of windings associated with the subset of windings;
• and
• provide, 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.
