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.

PARAMETER MODIFICATION SYSTEM, PARAMETER MODIFICATION METHOD, AND PARAMETER MODIFICATION PROGRAM FOR WORKING MACHINE

According to the present invention, a controller determines whether the current performance of a piece of equipment satisfies a determination criterion, on the basis of the current state of the equipment, acquired by a sensor. If the controller determines that the current performance of the equipment does not satisfy the determination criterion, the controller calculates a parameter with which the performance of the equipment satisfies the determination criterion, on the basis of the current state of the equipment, acquired by the sensor, and the determination criterion. The controller changes a parameter managed by a storage device to the parameter calculated by the controller.
