<p>A method of controlling the hydraulic actuation of the clutches and the synchronizers (24) in a dual clutch transmission (10) in the event of a clutch or synchronizer fault. The method includes the steps of determining which clutch is faulted when a clutch-on fault is detected, then commanding an interruption of engine torque to the faulted clutch and a neutralization of all synchronizers (24) of the same axis shaft as the faulted clutch. The method further senses if synchronizer actuator(26)-on fault has occurred, then determines which synchronizer (24) is faulted if an actuator(26)-on fault has is detected. The method steps further include preventing the further actuation of the other synchronizers (24) on the same axis shaft as the faulted actuator (26).</p> |
