Title: METHOD FOR GENERATING DRIVING NOISES, ACOUSTICS CONTROLLER AND MOTOR VEHICLE
Abstract:
The invention relates to a method for operating an electric motor, wherein a driving-performance-related torque setpoint is transmitted (P3) from a driving dynamics controller (1) to an acoustics controller (2) designed as a control unit. An input value (3) for defining an acoustic signal and a phase angle (Φ) of a rotor of the electric motor from a power electronics unit (4) are also received by the acoustics controller (2). In order to generate a dynamic torque setpoint (Mdyn), at least one torque clock pattern of an internal combustion engine dependent on the phase angle (Φ) of the rotor of the electric motor is modulated onto the driving-performance-related torque setpoint (MP) by the acoustics controller (2), wherein the dynamic torque setpoint (Mdyn) is created in such a way that a noise is generated (P6) by the electric motor and/or a drivetrain according to the input value (3). The dynamic torque setpoint (Mdyn) is transmitted (P7) to a power electronics unit (4).
