Patent ID: 8818662

Claim:
A drive train of a mobile vehicle, comprising: an internal combustion engine; and a load device driven by the internal combustion engine and defining at least one operating function of the machine; wherein the internal combustion engine is controlled by an electronic engine control unit and the load device is controlled by an electronic control unit, wherein a low idle speed for operation of an unloaded internal combustion engine is stored in the engine control unit of the internal combustion engine, wherein the electronic control unit recognizes a pause in the operation of the load device during which no operating function is activated, and during the pause in operation the electronic control unit transmits a speed setpoint (n Standby ) for standby operation of the internal combustion which is below the low idle speed (n uL ) to the engine control unit to operate the internal combustion engine at no load during a pause in operation at the speed setpoint (n Standby ) which is below the low idle speed (n uL ) for standby operation, wherein the electronic control unit is in communication on an input side with at least one position encoder which, when an operating function is activated, emits an encoder signal for the operating function of the load device to the control unit, whereby the control unit recognizes a pause in operation when there is no encoder signal, and wherein during the operation of the internal combustion engine at the speed setpoint (n Standby ) for standby operation and when an encoder signal from the position encoder is transmitted to the control unit for an operating function of the load device, the control unit transmits a required speed setpoint to the engine control unit for the operating function, wherein the control unit inhibits the start of the operating function of the load device until the internal combustion engine reaches low idle speed (n uL ).
