Adaptive Engine Torque Compensation with Driveline Model

Engine net torque is the total torque generated by the engine side, and includes the fuel combustion torque, the friction torque, and additionally the starter motor torque in case LIGHT BUCKWHEAT FLOUR of hybrid vehicles.The engine net torque is utilized to control powertrain items such as the engine itself, the transmission clutch, also the engine clutch, and it must be accurate for the precise powertrain control.However, this net torque can vary with the engine Drain Pump operating conditions like the engine wear, the changes of the atmospheric pressure and the friction torque.

Thus, this paper proposes the adaptive engine net torque compensator using driveline model which can cope with the net torque change according to engine operating conditions.The adaptive compensator was applied on the parallel hybrid vehicle and investigated via MATLAB Simcape Driveline simulation.
