-38 Abstract STABILITY SYSTEM FOR AN ARTICULATED MACHINE The real time state and stability of a machine (100) are determined and the future stability of the machine is predicted based on different potential machine operations. Sensor inputs including machine speed and acceleration, lift height of a payload, an articulation angle of the machine, a position of the machine, a pitch angle and a roll angle of the machine are used to generate a model for estimating a time series of real time and future values for the degree of stability of the machine by solving a kinematic equation and inputting other machine operational parameters during a timestep of a series of timesteps based at least in part on an estimate of the location of the center of gravity of a first portion of the machine in combination with the payload carried by the machine relative to a predetermined point, and the location of the center of gravity of a second portion of the machine relative to the predetermined point in a subsequent timestep. Visible or audible indications of the machine's current degree of stability and hypothetical future degrees of stability at different potential states of the machine are output. -a CO 00coC uj CCo> S< C=> Cl) C) 001 C) cn Q LU ci L -U uJ < JQ LU LQU >cF- CDU UJJ (uC) -i_~C .c IUC d_ I=- <t- C.C) C) ( LU C) LL.
