Electric Vehicle Sound Enhancement Systems And Methods

A vehicle audio system, comprising:

• at least one memory comprising computer executable instructions;
• at least one processor configured to read and execute the computer executable instructions, the computer executable instructions causing the at least one processor to:
• set 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;
• set 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,
• based on the audio characteristics, apply power to speakers to output sound within a passenger cabin of the vehicle.

A non-transitory computer readable medium comprising computer executable instructions, the computer executable instructions configured to cause a processor to perform a method, the method comprising:

• setting 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;
• setting 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,
