Electric vehicle sound enhancement systems and methods
First Claim
1. An audio system of a vehicle, comprising:
- an acceleration state module that sets an acceleration state signal to a first state when a longitudinal acceleration of the vehicle is greater than a first predetermined acceleration,wherein the first predetermined acceleration is positive;
a sound control module that selectively sets audio characteristics for an acceleration event in response to determinations that all of;
(i) the acceleration state signal is in the first state;
(ii) an electric motor is outputting positive torque to a powertrain of the vehicle;
(iii) an accelerator pedal position (APP) is greater than a predetermined APP,wherein the predetermined APP is at least 50 percent of a predetermined maximum APP;
(iv) a selected gear ratio of a transmission of the vehicle is greater than or equal to a predetermined gear ratio,wherein the predetermined gear ratio is at least a fifth gear ratio of the transmission; and
an audio driver module that, based on the audio characteristics, applies power to speakers to output sound within a passenger cabin of the vehicle.

Abstract
An audio system of a vehicle includes: an acceleration state module that sets an acceleration state signal to a first state when a longitudinal acceleration of the vehicle is greater than a first predetermined acceleration, where the first predetermined acceleration is positive; a sound control module that selectively sets audio characteristics for an acceleration event in response to determinations that all of: (i) the acceleration state signal is in the first state; (ii) an electric motor is outputting positive torque to a powertrain of the vehicle; and (iii) a driver is applying pressure to an accelerator pedal; and an audio driver module that, based on the audio characteristics, applies power to speakers to output sound within a passenger cabin of the vehicle.
