Abstract
A method for controlling a clutch for an engine-powered system in an automotive vehicle is provided. In one embodiment, the engine-powered system is an air conditioner system. The method includes the step of generating an engine roll signal responsive to an oscillating roll movement of an engine of the vehicle about a torque roll axis . The engine roll signal is indicative of an oscillating engine roll acceleration about the torque roll axis . The method further includes the step of determining a direction of the oscillating roll movement utilizing the engine roll signal. Finally, the method includes the step of actuating the clutch responsive to an operational parameter of the engine-powered system and the direction of the oscillating roll movement.
