Method for operating drive train in motor vehicle, involves calculating effective wheel torque of driving wheels of motor vehicle, where internal combustion engine is coupled or uncoupled with drive wheels

摘要

The method involves calculating the effective wheel torque of the driving wheels (18,20) of a motor vehicle. An internal combustion engine (14) is coupled or uncoupled with the drive wheels according to a function of the calculated wheel torque. A coupling torque of the internal combustion engine is initially determined.
