Abstract

A method for controlling the speed of a work vehicle during downhill operation may include controlling an operation of at least one of an engine or a transmission of a work vehicle so as to maintain the work vehicle operating at a requested speed and identifying an operating condition of the work vehicle that provides an indication that the work vehicle is traveling downhill. In addition, the method may include determining whether at least one pre-condition for downshifting the transmission from a current gear ratio to a downshift gear ratio is satisfied when the operating condition indicates that the work vehicle is currently traveling downhill. Moreover, when it is determined that the pre-condition(s) is satisfied, the method may include controlling the operation of the transmission such that the transmission is downshifted from the current gear ratio to the downshift gear ratio.
