17. A system for controlling at least one of noise and/or vibration in a vehicle having a powertrain, the system comprising:
-
a vibration sensing module that senses whether noise/vibration is present in the vehicle; and
a control module that, while at least one of noise and/or vibration is sensed, adjusts an operating point of the powertrain while maintaining a constant powertrain output power to reduce the at least one of noise and/or vibration. - View Dependent Claims (18, 19, 20)

21. A system for controlling noise/vibration in a vehicle having a powertrain, said method comprising:
-
a vibration sensing module that senses and compares at least one of noise and/or vibration to a threshold while the vehicle is operating in an operating range conducive to at least one of noise and/or vibration; and
a control module that, based on a result of the comparing by said vibration sensing module, adjusts an operating point of the powertrain to shift vehicle operation outside the range. - View Dependent Claims (22, 23, 24, 25)
