System and method for motor torque reduction

A method for reducing drag torque in motors of a steer-by-wire system, the method comprising:

• by a first electronic control unit (ECU) of a first powerpack of the steer-by-wire system:
• determining whether a fault exists in at least one of a plurality of first switches of a first inverter circuit connected between the first ECU and a first motor of the first powerpack, the first motor being one of the motors;
• and
• dynamically adjusting, in response to determining that the fault exists in the at least one of the plurality of first switches and while a vehicle in which the steer-by-wire system is installed is in operation, an operating status of the plurality of first switches based on an operating status of the first motor,
• wherein the steer-by-wire system further comprises a steering rack operably coupled to the first motor of the first powerpack and the second motor of the second powerpack, the steering rack configured to be linearly movable in response to rotation of at least one of the first motor and the second motor.
