A method for generating a steering command for controlling a vehicle is provided. The method includes: generating a first vehicle steering control torque command by a steering controller in the vehicle while the vehicle is driven in a semi-autonomous mode; generating an impedance-adjusted vehicle steering angle command based on a first vehicle steering angle command that was generated to compensate for a trajectory error, and a measured driver steering torque command generated in response to navigation of the vehicle using a steering wheel; generating an impedance-adjusted vehicle steering control torque command by the steering controller in the vehicle based on a difference between the impedance-adjusted vehicle steering angle command and a measured vehicle steering angle command; generating a steering command by a power steering system in the vehicle based on the measured driver steering torque command and the impedance-adjusted vehicle steering control torque command; and operating the vehicle in accordance with the steering command.
