Abstract
A steer by wire includes a steering wheel holding system. An emulator controller receives vehicle data from vehicle systems and determines whether a vehicle is in one of a driving mode and a non-driving mode. When the vehicle is in the driving mode, the emulator controller transmits a command to an emulator switching system to electrically couple the phases of an emulator motor to a power source to enable the emulator motor to implement steer by wire operations placing the steering wheel in an un-hold mode. When the vehicle is in the non-driving mode, the emulator controller transmits a command to the emulator switching system to electrically couple the phases of the emulator motor to ground to short the phases of the emulator motor to ground to generate a resistive torque to resist rotational movement of a steering wheel of the vehicle placing the steering wheel in a hold mode.
