Claim:
1. A control system for use with a sound controller that is configured to transmit sounds to a passenger cabin of a vehicle, the vehicle including a transmission having multiple gears and being controllable to select a different gear resulting in either an upshift or a downshift, and an accelerator pedal that is configured to be manually actuated to control a throttle valve to regulate a supply of air to an engine, the vehicle engine being operable in multiple different modes and engine speeds, the control system comprising: a shift sensor configured to output data indicative of a transmission target gear; an accelerator pedal sensor that is configured to output data indicative of a position of the accelerator pedal; and a controller configured to control operation of the sound controller in accordance with a sound control logic that is based on vehicle engine mode, transmission target gear selection, accelerator pedal position, and vehicle engine speed, the controller also being configured to control operation of the sound controller in accordance with an audible downshift logic that is separate from the sound control logic and is specifically tailored to only perform the following operation: if the transmission target gear corresponds to a downshift of the vehicle transmission and the accelerator pedal position is not above the predetermined threshold, then the audible downshift logic controls the sound controller to enhance engine sound transmitted to the passenger cabin.
