Abstract: A system for estimating a payload includes a torque sensor, a grade detector, and a machine acceleration sensor. A controller compares the angle of inclination to its threshold, compares the rate of change in the angle of inclination to its threshold, and compares the machine acceleration to its threshold. An estimate of the payload is determined based upon the output torque from the prime mover, the angle of inclination of the machine, and the unloaded mass but only if the angle of inclination of the machine is greater than the angle of inclination threshold, the rate of change in the angle of inclination is less than the inclination rate of change threshold, and the machine acceleration is less than the acceleration threshold.

Abstract: A method implemented by a programmable controller to estimate the payload mass in a bed of a moving hauling machine. The method includes determining whether the machine is at a steady acceleration and grade, estimating transmission torque, calculating axle torque at at least one of the ground engaging elements, calculating force at said ground engaging element, determining the acceleration of the machine, calculating mass of the machine with the payload, adjusting the calculated mass of the machine with the payload based upon an estimated machine mass and rolling resistance, and providing an estimate of the mass of the payload.

Abstract: This disclosure is generally drawn to methods, systems, devices and/or apparatus related to compressing the size of engineering development maps. Specifically, some of the disclosed example methods, systems, devices and/or apparatus relate to compression of an engineering development map (e.g., kinematic map) based on a given fixed size and/or based on a given target error tolerance value using modified Douglas-Peucker search techniques.
