Method of Controlling a Double Clutch in a Vehicle Transmission, and Clutch Control System for Controlling a Double Clutch

摘要

The present invention concerns a method of controlling a double clutch transmission (1) comprising two clutches (2a, 2b) one of which that is transmitting torque being the active clutch whilst the other one constituting the incoming clutch characterized by combining the incoming clutch preparation and the torque handover from the active clutch by over actuating the incoming clutch and shutting off the active clutch in a non proportional way, based on a feedback signal from the incoming clutch.

主权项

1. A method of transferring torque from an active clutch to an incoming clutch in a double clutch transmission, the method comprising:
preparing the incoming clutch so as to be ready for taking over the torque transmission from the active clutch, wherein the preparation is achieved by over actuating the incoming clutch; maintaining the over actuation of the incoming clutch before a touch point for engaging the incoming clutch is reached; receiving a feedback signal which indicates that all of the torque transmission has been transferred to the incoming clutch from the active clutch while the incoming clutch is over actuated; and shutting off the active clutch based, at least in part, on receiving the feedback signal.
