Abstract
Methods and systems for controlling the operation of a dual mode engine accessory, such as a dual mode cooling pump. The dual mode device has two modes of operation, an electric motor operation and a mechanical pulley-driven operation. A friction clutch mechanism controlled by the control system is utilized to switch between the two modes of operation. The speed of the electrical motor can be changed to be substantially the same as, or changed in the direction of, the speed of the mechanical pulley-driven system.
