Abstract
A speed-limiting accessory drive system is provided that limits the speed range over which an engine-driven accessory operates while maintaining the operating speed range of the engine. A torque-transmitting mechanism is selectively engagable to operatively connect the engine and the accessory. A controller is configured to maintain the torque-transmitting mechanism in an engaged state only when monitored engine speed is within a predetermined speed range and to control a drive motor to drive the driven accessory when the monitored engine speed is not within the predetermined range. A method of controlling the speed of at least one driven accessory, which may be carried out using the speed-limiting accessory drive system, is also provided.
