Patent ID: 7748147

Claim:
A system for automated operation of a work vehicle, the system comprising: a boom having a first end and a second end opposite the first end; a first hydraulic cylinder associated with the boom; a first sensor for detecting a boom angle of the boom with respect to a support near the first end; an attachment coupled to the second end of the boom; a second hydraulic cylinder associated with the attachment; a second sensor for detecting an attachment angle of the attachment with respect to the boom; a switch for accepting a command to enter a preset position from another position; a controller for controlling the first hydraulic cylinder to attain a boom angle within a target boom angular range and for controlling the second cylinder to attain an attachment angle within a target attachment angular range associated with the preset position in response to the command; and a leveling module for updating control data for controlling the attachment angle of the attachment within a minimum update frequency that is proportional to at least one of acceleration and velocity of the boom.
