    Abstract: An autonomous mode controller (61) that outputs an acceleration command (SAa), a braking command (SBa) and a torque command (Ta) is connected to a steering actuator (33) and a traveling drive unit (52). The steering actuator (33) generates combined torque (T1) based upon steering torque (Tm) from a steering handle (32) and the torque command (Ta), and controls a steering angle (θ) of a vehicle based upon the combined torque (T1). The traveling drive unit (52) selects a larger one of an acceleration command (SAm) by an accelerator pedal (50) and the acceleration command (SAa) as an acceleration command (SA), and selects a larger one of a braking command (SBm) by a brake pedal (51) and the acceleration command (SBa) as a braking command (SB). The traveling drive unit (52) controls a vehicle speed based upon the acceleration command (SA) and the braking command (SB).

    Abstract: A system for controlling a machine during an autonomous material moving operation includes a terrain sensing system, a position sensing system, and a ground engaging work implement. A controller is configured to determine the topography of the work surface, generate a first target profile, generate signals to autonomously operate the machine along a work surface, receive a plurality of signals associated with a plurality of necessary input conditions, and generate a pause command based upon an absence of one of the plurality of necessary input conditions to define a pause condition. The controller may determine the position of the machine, determine an estimate of an amount of material being moved, generate a second target profile, and generate signals to re-start autonomous operation of the machine based upon the second target profile after elimination of the pause condition.
