Feedforward control of a parallel hybrid launch clutch

Hybrid Electrical Vehicles (HEV) are a very promising approach to save fuel and minimize exhaust emissions. The drivetrains of HEV are equipped with at least one Electric Machine (EM) in addition to the Internal Combustion Engine (ICE). Therefore it is possible to operate the Internal Combustion Engine (ICE) in more efficient working points or to shut it down if the efficiency is too low. Despite of the fuel savings, the drivability can be increased by realizing gear shifts without an intermission in the wheel torque or a noticeable jerk.
