Work vehicle engine control systems operable in enhanced scheduled power reduction modes

Abstract:

Work vehicle engine control systems operable in enhanced engine protection (EP) modes, and associated methods and program products, include a memory storing a first default power profile having a first profile shape as expressed on a power/speed graph, which plots power output and engine speed along vertical and horizontal axes, respectively. A controller architecture is coupled to the memory and is operable in the enhanced EP mode in which the controller architecture: (i) generates a first dynamically-adjusted power profile by repeatedly fitting the first profile shape beneath a moving EP ceiling as expressed on the power/speed graph; (ii) utilizes the first dynamically-adjusted power profile to determine a power output target (PO.sub.TAR) corresponding to a current speed of the work vehicle engine; and (iii) schedules the power output of the work vehicle engine in accordance with the power output target (PO.sub.TAR).
