Abstract
Methods and systems for a transmission are provided. The method includes estimating a stroke position of the hydraulic control piston based on a pressure of a fluid in a hydraulic line and a valve and a coefficient of the hydraulic line, where the hydraulic line is coupled to a chamber of the hydraulic control piston. The method further includes controlling a pressure of fluid delivered from the valve to the hydraulic control piston based on the estimated stroke position to achieve a piston stroke set-point during a filling phase.
