Zusammenfassung:	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.
