  • Engine sound enhancement implementation through varying vehicle conditions
    Patent number: 8938079
    Abstract: Engine sound enhancement (ESE) for a vehicle includes determining a current rate of change (ROC) 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 and calculating an ESE value based on the current ROC in the position of the acceleration device. The ESE value reflects an intensity and tone quality of at least one of the exhaust and the engine of the vehicle. The ESE also includes receiving a current RPM value, comparing the RPM value and the ROC in the position of the acceleration device to corresponding pre-defined threshold values, the pre-defined threshold values mapped to ESE tunings, and activating one of the ESE tunings when each of the current RPM value and the current ROC in the position of the acceleration device meets a corresponding pre-defined threshold value.
