Embodiment Construction

[0065] In the following, for example figure 1 The material moving machine in the form of a wheel loader 10 is shown to describe the invention. The wheel loader 10 should be considered an example of a material moving machine for which a system according to the invention is included and / or a method according to the invention can be used.

[0066] However, it is also conceivable that the invention may be practiced with other types of material moving machinery, such as excavators (not shown) or bulldozers (not shown). Furthermore, it should be emphasized that although the invention is described herein with reference to a movable material moving machine, it is also contemplated that the moving machine could be a stationary moving machine.

[0067] figure 1 The material moving machine 10 in includes tool 12, and described tool 12 is in figure 1 The embodiment is illustrated as a bucket. Furthermore, the material moving machine 10 includes an actuation device 14 for raising and / o...

Abstract

The present invention relates to a system (18) for determining a material entity (32) to be removed from a pile (16) by means of an implement (12) of a material moving machine (10). The system (18) comprises means for generating a current pile shape (26) of the actual surface shape of the pile (16). Moreover, the system (18) is adapted to determine a nominal pile shape (28) of at least a portion of the pile (16). The nominal pile shape (28) is determined on the basis of at least the current pile shape (26) and information regarding the material type of the pile (16). Further the system (18) isadapted to determine a surplus volume (30) between the nominal pile shape (28) and the current pile shape (26) and the system (18) is adapted to determine the material entity (32) to be removed fromthe pile (16) on the basis of the surplus volume (30).

Description

technical field [0001] The invention relates to a system for determining a material entity to be removed from a stockpile according to the preamble of claim 1 . Furthermore, the invention relates to a material moving machine comprising such a system. Additionally, the invention relates to a method for determining material entities to be removed from a stockpile. Furthermore, the invention relates to a method for removing material from a stockpile. Background technique [0002] Material moving machinery can be used in a number of material moving operations. An example of this operation is moving material from a material pile. By way of example only, material removal from stockpiles may be performed while performing reprocessing of processed material. Non-limiting examples of material moving machines may be wheel loaders, excavators, and the like. [0003] Generally, the operation of moving material from a pile of material involves digging into the pile with a tool of the...
