Abstract:
1. A control method of the torque of a road vehicle comprising a powertrain system provided with an engine presenting a drive shaft and a driveline which transmits the torque generated by the engine to the road surface through the drive wheels; the method comprises the steps of: determining a target torque (T controlling the generation of torque by the engine on the basis of the target torque (T the method is characterized in that it comprises the further steps of: modeling the powertrain system as a single physical component which presents a characteristic mechanical inertia and a characteristic torsional elasticity and which must undergo a corresponding torsion to transmit a certain drive torque; determining a current load torque (T determining a target torsion (Δθ determining a current torsion (Δθ) of the powertrain system and a current torsion speed (Δθ′) of the powertrain system; determining a requested torque (T using the requested torque (T
