Drive train controlling method for motor vehicle, involves adjusting disturbance torque due to starting of transmission of clutch torque over friction clutch, where disturbance torque is compensated by actual adjusted clutch torque

摘要

The method involves controlling constant no-load speed of an internal-combustion engine during a no-load operation phase. Actual speed of the internal-combustion engine is detected by an incremental sensor. A friction clutch is made to act between a transmission and a drive unit of the internal-combustion engine. Disturbance torque lowering the no-load speed is adjusted due to starting of the transmission of the clutch torque over the friction clutch, where the disturbance torque is compensated by the actual adjusted clutch torque. The clutch torque is reconstructed from actual engine torque.
