Embodiment Construction

[0020] According to the drawing, the drive control of a mobile power machine 1 has a vehicle control device 3 for actuating a plurality of loads of the mobile power machine. These loads are, for example: traction drive 27 , which is represented by a traction drive pump; work hydraulics 29 , which is represented by a pump of the work hydraulics; and electric generator 31 .

[0021] All these loads 27 , 29 , 31 are coupled to and driven by the output shaft (Abtriebswelle), also called the engine shaft, of the diesel engine 25 . These loads are actuated by the vehicle control unit 3 via the control signal output 5 with the second control signal 39 .

[0022] In the vehicle control unit 3 , besides the mechanical power P required for the load (with regard to the engine shaft), the rotational speed specification unit 47 also determines the optimal or fixedly required rotational speed for the operation of the load. In this case, a speed range can also be determined, referring to: a...

Abstract

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 isconfigured 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 thepower 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.

Description

technical field [0001] The invention relates to a drive control device (Antriebssteuerungsanordnung) for a mobile work machine (mobile Arbeitsmaschine), which has a vehicle control device for controlling the load (Verbraucher) of the mobile work machine and has a device for actuating the mobile work machine Diesel engine control equipment for diesel engines. Furthermore, the invention relates to an interface on a vehicle control unit or an interface on a diesel engine control unit. Background technique [0002] Such drive controls and interfaces are known in principle. In the solution described by the applicant in German patent application DE 10 2013 214 732 A1, the vehicle control unit calculates the total power demand of the vehicle on the basis of all power demands (driving, working) that exist for the load as desired by the driver. A total energy coordinator is incorporated in the control structure of the vehicle, which predetermines, in particular for the diesel engin...
