A method of controlling an electric motor includes receiving a duty cycle for the electric motor for delivering a target torque from the electric motor, generating a pulse train, and pulsing the electric motor with the generated pulse train. Generating the pulse train being at least partially based on the received duty cycle. The generated pulse train optimized to improve at least one of noise, vibration, or harshness of the electric motor when compared to a constant pulse frequency.
