Drive Control Arrangement for a Mobile Working Machine and Interface

A drive control arrangement, for driving of consumers of a mobile working machine with a Diesel engine, includes a Diesel engine controller, vehicle controller, and interface. The engine controller is configured to actuate the Diesel engine via a first control signal. The vehicle controller is configured to (i) control the consumers via at least one second control signal, (ii) transfer a power demand, via the interface, to the engine controller, and (iii) receive feedback, via the interface, with reference to an available power from the Diesel engine. The interface is configured such that the power demand includes a value for a mechanical power and at least one speed interval value. When the engine is delivering a power according to the value of the power demand and/or with reference to the feedback, the engine controller is further configured to control a speed of the engine in a speed interval with reference to the at least one speed interval value.
