Abstract:
1. A construction machine, comprising: a machine frame; a plurality of ground engaging supports for supporting the machine frame; a milling drum supported from the machine frame for milling a ground surface, the milling drum having a drum width; at least one profile sensor configured to detect at least one profile parameter of a ground surface in front of the milling drum; at least one distance sensor configured to detect at least one distance parameter corresponding to a distance traveled by the construction machine; at least one depth sensor configured to detect at least one depth parameter corresponding to a milling depth of the milling drum; and an on-board processor located on the construction machine and communicated with the sensors, the processor being configured to determine a usage of the construction machine as a volume of material milled by the construction machine at least partially as a function of the profile parameter, the depth parameter and the distance parameter.
