Abstract
A method is described for controlling the power train of a work vehicle. The power train includes an engine with a fuel injection control and an infinitely variable transmission. The method include first determining an initial engine speed, an initial wheel speed, the actual engine speed, and the actual wheel speed. To improve comfort and reduce fuel consumption and emissions two steps are performed. First, the transmission ratio of the infinitely variable transmission will be increased if the actual engine speed is less than the initial engine speed, or decreased if the actual engine speed is greater than the initial engine speed. Second, while the transmission ratio remains constant, the engine speed will be adjusted until the engine speed is the same as the initial engine speed.
