Abstract
A method of generating warnings associated with a vehicle is provided. The method broadly includes the steps of: (a) receiving an indication that a warning relating to operation of an electric motor is appropriate; (b) generating a drive current for the electric motor; (c) superimposing a warning signal onto the drive current; and (d) driving the electric motor with the drive current and the superimposed warning signal such that the electric motor produces the warnings. The warning signal may produce an audio warning, a tactile warning, or a combination thereof.
