Abstract:
1. A method for implementing engine sound enhancement (ESE) for a vehicle, the method comprising: determining, via a controller, a current rate of change in a position of an acceleration device of the vehicle from sensor data received from at least one sensor in communication with the acceleration device; calculating an ESE value based on the current rate of change in the position of the acceleration device, the ESE value reflecting an intensity and tone quality of at least one of an exhaust and an engine of the vehicle; receiving a current revolutions-per-minute (RPM) value of the engine; comparing the current RPM value and the current rate of change in the position of the acceleration device to corresponding pre-defined threshold values, the pre-defined threshold values mapped to engine sound enhancement (ESE) tunings; and activating one of the ESE tunings when each of the current RPM value and the current rate of change in the position of the acceleration device meet a corresponding one of the pre-defined threshold values.
