Abstract

A multi clutch transmission for a vehicle has a control system configured to regulate the operation of two clutches during the torque phase of a gear shift. The control system is programmed with one or more predetermined handover functions, which define a set torque profile for each clutch during the torque phase. The control system shifts the set torque profiles for the two clutches to take account of changes in the total torque demand, whereby both clutches carry a percentage of any change during the gear shift. The control system generates values indicative of the total clutch torque demand during the gearshift, e.g. based on slip or engine speed data, and apportions any change in accordance with the respective predetermined handover function.
