Control-oriented modeling and torque estimations for vehicle driveline with dual-clutch transmission

•A control-oriented model for a vehicle driveline with DCT is developed with practical aspects.•A torque observer is designed to estimate torque through both clutches and the drive shaft in a DCT.•The observer is based on the control-oriented model and uses data available on production cars.•The effectiveness of the developed model and the torque observer is demonstrated by experiments.•The proposed methods of modeling and torque estimation are useful for accurate powertrain controls.
