Inertial torque determining method for internal combustion engine of motor vehicle, involves determining inertial torque from moment of inertia of internal combustion engine and gradient of engine speed when engine turns without injection

摘要

The method involves determining inertial torque (CINERTj) from moment of inertia (SJ) of an internal combustion engine and gradient of engine speed when the engine turns during a change ratio of a mechanical gearbox associated to the engine without fuel injection. The internal combustion engine is integrated with a clutch. Driving torque of the engine is determined from a sum of cartographed driving torque (CPE) and a corrective term defined according to the inertial torque. Independent claims are also included for the following: (1) a method for determining driving torque of an internal combustion engine (2) a method for determining driving torque of loss.
