Power/Economy Mode Control System For An Agricultural Vehicle

摘要

An agricultural vehicle includes a chassis and an engine, transmission and operator station which are each carried by the chassis. The engine has a maximum operating speed. The transmission includes a continuously variable output. A power/economy switch which is positioned within the operator station provides a first output signal indicative of a power mode and a second output signal indicative of an economy mode. A controller is coupled with each of the engine, the transmission and the power/economy switch. The controller receives the second output signal from the power/economy switch and controls each of the engine and the transmission to be in an economy mode, whereby an operating speed of the engine is limited to a reduced maximum speed which is below the maximum operating speed, and the continuously variable output of the transmission is increased to offset for the reduction in engine operating speed.
