Abstract:
A system for controlling at least one output parameter of an internal combustion engine in a motor vehicle, comprising:an engine controller for receiving a plurality of engine operating parameters and for providing an output parameter control signal in response to the values of said operating parameters; at least one sensor operatively connected with the controller, for sensing an NVH condition capable of being sensed by an occupant of the vehicle, with said sensor producing a NVH signal in response to the sensing of said NVH condition; and a signal processor operatively associated with said controller, for receiving said NVH signal, with said signal processor comprising a comparator for comparing a characteristic of the NVH signal with a predetermined human threshold value, and with the controller using the result of said comparison as one of said plurality of operating parameters for providing said output parameter control signal.
