Abstract
This invention relates to a drive train (1) of a mobile vehicle with an internal combustion engine (2) and a load device (3) driven by the internal combustion engine (2). The internal combustion engine (2) is controlled by an electronic engine control unit (4) and the load device (3) is controlled by an electronic control unit (5). A low idle speed (nuL) for the operation of the internal combustion engine at no load is stored in the engine control unit (4). The electronic control unit (5) detects a pause in the operation of the load device (3) and transmits a speed setpoint (nStandby) for standby operation of the internal combustion engine to the engine control unit (4) to operate the internal combustion engine (2) at idle during a pause in operation at the speed setpoint (nStandby), which is below the low idle speed (nuL) for standby operation.
