Abstract
A system and method for determining filling parameters of a wet clutch system used with a transmission is provided. The method comprises the steps of collecting information about the torque output of the torque converter of the transmission during a filling process associated with the wet clutch system, analyzing the signal associated with the torque output of the torque converter within a time period of the filling process associated with the wet clutch system, and identifying when the signal associated with the torque output of the torque converter changes with respect to the time period of the filling process of the piston to determine a filling parameter associated with the wet clutch system. The system and method eliminates a need for recalibrating the transmission and accommodates production variances for components and assembly of systems using wet clutch systems.
