Abstract:
A power boost control system is provided for an agricultural vehicle with an engine which is normally governor controlled to run at throttle-selected constant engine speed up to a normal or rated engine speed. The power boost control system receives a road speed signal. Power boost is enabled if the sensed road speed is greater than an âonâ threshold, above which is considered to be a transport speed. Power boost is disabled if sensed road speed is less than an âoffâ threshold, below which is considered to be less than a transport speed. When power boost is enabled, the controller will increase maximum power limits to above normal levels, so that, for example, the desired road or transport speed can be maintained as the vehicle goes up a hill.
