  • Fork position and synchronization control in a dual clutch transmission using pressure control solenoids
    Patent number: 8844393
    Abstract: A dual clutch transmission (DCT) control module includes a position control module that actuates a shift fork of the DCT during a first shift state based on a measured shift fork position and a target shift fork position. A force control module adjusts a control force associated with the shift fork during a second shift state based on synchronizer slip.
