Abstract
A control system is provided for a vehicle having an engine which transitions between an activated mode and a deactivated mode. The control system includes a vehicle bus transmitting a signal indicating a vehicle selected mode and if the engine is operating in one of the activated mode and the deactivated mode. The control system also includes an engine sound enhancement (“ESE”) module configured to receive the signal. The ESE module is configured to select at least one ESE tone and a set of ancillary tones associated with one or more of the deactivated mode, the activated mode, and an activation transition. The ESE module selects a specific type of ancillary tones based on the vehicle selected mode.
