Intelligent assist system for a work machine

A work machine controller that is coupled to the boom assembly may comprise of a controller with a memory that stores computer-executable instructions and a processor that executes instructions. The instructions include monitoring a first position signal from the first boom position sensor, a second position signal from the second boom position sensor, the load signal, and the orientation signal. The instructions then include calculating a load vector based on the load signal and the orientation signal, generating a disorientation signal based on the load vector and a direction of travel, determining if the disorientation signal is outside a predetermined threshold, and actuating one or more of the actuators and the ground-engaging mechanism to reorient the load when the disorientation signal exceeds the predetermined threshold.

SYSTEMS AND METHODS FOR CONTROL OF EXCAVATORS AND OTHER POWER MACHINES

A power machine can include operator input devices and a control system configured to command movement of actuators based on operator inputs received from the operator input devices. Movement of one or more of the actuators can be commanded based on input at one or more of the operator input devices and a response curve selected from a plurality of different response curves. Movement of one or more of the actuators can be based on a selected control mode for the power machine that corresponds to a selected control-function mapping of the operator input devices to the one or more actuators. A lift arm can be variously controlled to execute automatic or other operations. An excavator can be operated in a sustained-speed travel mode. Actuation of a bucket or other implement can be implemented based on signals from a material sensor.

Work machine

When a machine-control ON/OFF switch is switched to the ON position, a controller outputs either a first control signal generated by an operation lever or a second control signal that operates a boom cylinder in accordance with a predetermined condition; when the ON/OFF switch is switched to the OFF position, the controller outputs the first control signal; when a control signal has been switched from one of the first control signal and the second control signal to the other control signal by the operation of the ON/OFF switch, the controller applies a rate limit to the control signal, and controls the boom cylinder on the basis of the control signal obtained after the limitation.
