发明名称 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.

主权项 1. An agricultural vehicle, comprising: a chassis; an engine carried by said chassis, said engine having a maximum operating speed; a transmission carried by said chassis, said transmission including a continuously variable output; an operator station carried by said chassis; an input for selecting between a power mode and an economy mode, said power/economy input providing a first output signal indicative of a power mode and a second output signal indicative of an economy mode; and a controller coupled with each of said engine, said transmission and said power/economy input, said controller receiving said second output signal from said power/economy input and controlling each of said engine and said transmission to be in an economy mode, whereby an operating speed of said engine is limited to a reduced maximum speed which is below said maximum operating speed, and said continuously variable output of said transmission is increased to offset for the reduction in engine operating speed a road mode input configured for providing a road mode output signal to the controller, and wherein said controller controls each of said engine and said transmission to be in said economy mode when said controller receives both of said second output signal and said road mode output signal wherein road mode functions as an interlock for mechanical functions on the agricultural vehicle when actuated.
