1. A dual clutch transmission (DCT) control module, comprising:
a position control module that, using position-based control, controls a force applied to a piston to actuate a corresponding shift fork of a DCT; and a force control module that, using force-based control, increases a control force applied to the piston to control the shift fork;
wherein the position control module, using the position-based control, controls a force applied to the piston to actuate the shift fork during a first shift state based on a measured shift fork position and a first target shift fork position;wherein the force control module, using the forced-based control and in response to the first shift state ending and the shift fork reaching the first target shift fork position, increases the control force applied to the piston to control the shift fork during a second shift state based on a requested force and synchronizer slip; andwherein the position control module, in response to the second shift state ending, resumes using the position-based control to control a force applied to the piston to actuate the shift fork to a second target shift fork position. |
