Overview 

This document contains information on:

• Engine sound generation

General 

The engine sound function is used to simulate engine and exhaust system sounds in the vehicle interior. Improved acoustic feedback optimizes the driving feel.

Function requirement 

• Engine running.

Engine sound generation 

The following signals define the current driving condition:

• Drive program/engaged drive range
• Vehicle speed
• Engine torque
• Engine speed

The sound system amplifier control unit or the multimedia system control generates a simulated engine sound on the basis of the driving condition. The speaker system outputs the simulated sound even when no audio source is active. If audio output is active, the simulated sound expands the current audio source.
