Abstract
A target engine revolution speed is calculated based on the throttle position of an engine such that the amount of change in the target engine revolution speed with respect to time is limited. According to the target engine revolution speed thus calculated, a target motor speed ratio, which is a target value for the ratio of the revolution speed of a motor in a hydrostatic transmission unit to the revolution speed of the engine, is set. With this target motor speed ratio, the angle of at least either of discharge controlling swash plates is adjusted.
