Automated control of boom or attachment for work vehicle to a preset position

摘要

A work vehicle (250) comprises a boom (252). A first hydraulic cylinder (12) is associated with the boom (252). A first sensor (14) detects a boom angle of the boom (252) with respect to a support near the first end (275). An attachment (251) is coupled to the second end (276) of the boom (252). A second sensor (18) detects an attachment angle of attachment (251) with respect to the boom (252). A second cylinder (16) is associated with the attachment. A switch (22) accepts a command to move to or enter a preset position from another position. A controller (20) controls the first hydraulic cylinder (12) to attain a boom angle within a target boom angular range and for controlling the second cylinder (16) to attain an attachment angle (255) within a target attachment angular range associated with the preset position in response to the command.
