Abstract (en)

A hydrostatic transmission system includes a pump including a rotatable swashplate. Rotation of the swashplate effects a change in volumetric displacement of the pump. An actuator is coupled to the swashplate and effects rotation of the swashplate to change the volumetric displacement of the pump. An electronic controller is operatively coupled to the actuator and commands the actuator to effect rotation of the swashplate.
