PAYLOAD DETERMINATION SYSTEM AND METHOD

摘要

In an exemplary embodiment of the present disclosure, a payload determination method associated with a machine includes determining first head-end and first rod-end pressures of a first actuator operably connected to a boom of the machine as the boom is raised across a position at a reference lift angle. The method further includes determining first head-end and first rod-end pressures of a second actuator operably connected to a work tool of the machine as the boom is raised across the position. The method further includes determining a weight of a payload carried by the work tool based on the first head-end pressure of the first actuator, the first rod-end pressure of the first actuator, the first head-end pressure of the second actuator, the first rod-end pressure of the second actuator, and a determined pitch angle of the machine. In such an exemplary method, the payload is carried by the work tool during at least one of the determining steps described above.

1. A payload determination method associated with a machine, comprising:
a) raising a boom of the machine from a first position at a minimum lift angle of the boom to a second position at a maximum lift angle of the boom; b) determining first head-end and first rod-end pressures of a first actuator operably connected to the boom as the boom is raised across a third position at a reference lift angle of the boom between the minimum and maximum lift angles; c) determining first head-end and first rod-end pressures of a second actuator operably connected to a work tool of the machine as the boom is raised across the third position; d) lowering the boom from the second position to the first position; e) determining second head-end and second rod-end pressures of the first actuator as the boom is lowered across the third position; f) determining second head-end and second rod-end pressures of the second actuator as the boom is lowered across the third position; and g) determining a weight of a payload carried by the work tool based on the first and second head-end pressures of the first actuator, the first and second rod-end pressures of the first actuator, the first and second head-end pressures of the second actuator, the first and second rod-end pressures of the second actuator, and a determined pitch angle of the machine, wherein the payload is carried by the work tool during at least steps b, c, e, and f.
