Abstract
The present disclosure relates to a method for operating an electric motor, wherein a vehicle dynamics controller transmits a driving-performance-related torque setpoint to an acoustic controller configured as a control device. The acoustic controller receives an input value for defining an acoustic signal as well as a phase angle of a rotor of the electric motor from the power electronics as well. To generate a dynamic torque setpoint, the acoustic controller modulates onto the driving-performance-related torque setpoint at least one torque pattern that depends on the phase angle of the rotor of the electric motor, wherein the dynamic torque setpoint is such that a sound according to the input value is generated by the electric motor and/or a drive train. The dynamic torque setpoint is transmitted to power electronics.
