Patent ID: 7797860

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 position based on a first linear position of a first movable member associated with the first hydraulic cylinder; 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 position based on a second linear position of a second movable member associated with the second hydraulic cylinder; a switch for accepting a command to enter a preset position state from another position state; a limiter for limiting the preset position based on at least one of a maximum rollback angle of the attachment and a cutting edge position of the attachment; and a controller for controlling the first hydraulic cylinder to attain a target boom position and for controlling the second cylinder to attain a target attachment position associated with the preset position state in response to the command wherein the controller gradually reduces one of a deceleration and an acceleration of the first hydraulic cylinder in response to detecting the boom entering within a predetermined range of the target boom position.
