Payload estimation in four wheel drive loaders
Dynamic payload estimation in hydraulically actuated linkages is a diffucult task compounded by friction, compressibility, manufacturing variation, and linkage nonlinearity among other things. This problem is made even more difficult when the linkage is mobile as is often the case with off-highway equipment such as four-wheeldrive loaders, cranes, and excavators. The rigid body motion of this type of equipment affects the gravitational loads seen in the linkage and impact the payload estimate. The commercially available state-of-the-art load estimation solutions rely on the mobile machine becoming pseudo-static in order to maintain accuracy. This requirement increases the time required to move the material and decreases the productivity of the machine. A novel solution to this problem that enables the machine to remain dynamic and still accurately estimate the payload is discussed in this paper. Development and implementation on an actual four-wheel-drive loader is shown.
