  • Patent number: 7797860
    Abstract: A method and system for automated operation of a work vehicle comprises a boom having a first end and a second end opposite the first end. A first hydraulic cylinder is associated with the boom. A first sensor detects a boom position based on a first linear position of a first movable member associated with the first hydraulic cylinder. An attachment is coupled to the second end of the boom. A second hydraulic cylinder is associated with the attachment. A second sensor detects an attachment position based on a second linear position of a second movable member associated with the second hydraulic cylinder. A switch accepts a command to move to or enter a preset position state from another position state. A controller controls 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.

  • Patent number: 7752778
    Abstract: A first hydraulic cylinder is associated with the boom having a first end and a second end opposite the first end. A first sensor detects a boom angle of a boom with respect to a support (or a vehicle) near the first end. An attachment is coupled to the second end of the boom. A second hydraulic cylinder is associated with the attachment. A second sensor detects an attachment angle of attachment with respect to the boom. An accelerometer detects an acceleration or deceleration of the boom. A switch is arranged to accept a command to move to a preset position from another position. A controller is capable of controlling the first hydraulic cylinder to attain a boom angle within the target boom angular range and for controlling the second cylinder to attain an attachment angle within the target attachment angular range associated with the preset position in response to the command in conformity with at least one of a desired boom motion curve and a desired attachment motion curve.

  • Patent number: 7752779
    Abstract: A first hydraulic cylinder is associated with a boom. A first sensor detects a boom angle of a boom with respect to a support (or a vehicle). An attachment is coupled to one end of the boom. A second hydraulic cylinder is associated with the attachment. A second sensor detects an attachment position of attachment based on a second linear position of a second movable member of the second hydraulic cylinder. An accelerometer detects an acceleration or deceleration of the boom. A switch is arranged to accept a command to move to a preset position from another position. A controller is capable of 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 in response to the command in conformity with at least one of a desired boom motion curve and a desired attachment motion curve.
