Adaptive control for clutch engagement on starting up of vehicle

Control problem is investigated for dry clutch engagement process during a standing start in AMT vehicles. Based on the control-oriented simplified driveline dynamic model under consideration of parametric uncertainties of the driveline due to the mechanical wear and tear, the elastic deformation of shaft and so on, an adaptive tracking control strategy is examined paying particular attention to the engagement comfort while not deteriorating the slipping time by using the crankshaft speed and the clutch disk speed as state variables and the engine torque and the clutch torque as control variables. The resulting analytically derived adaptive controller guarantees the fast smooth engagement of the clutch and the engine stall avoidance. Simulation results show the good performance obtained with the proposed controller.
