  • Patent number: 8386133
    Abstract: A first sensor detects a boom angle of a boom with respect to a support. An attachment is coupled to the boom. A second cylinder is associated with the attachment. A second sensor detects an attachment angle of the attachment with respect to the boom. An accelerometer detects an acceleration or deceleration of the boom. A switch accepts a command to enter a ready position state from another position state. A controller controls 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 ready position state 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: 8036797
    Abstract: A method and system for controlling a vehicle comprises a torque detector for detecting a first torque level and a second torque level applied to at least one wheel of the vehicle. The first torque level is associated with a lower boom position of a boom. An accelerometer detects an acceleration level of the boom during or after raising of the boom. A first hydraulic cylinder is capable of raising a boom from the lower boom position to raise an available torque from the first torque level. A second hydraulic cylinder is adapted to upwardly rotate or curl a bucket associated with the vehicle if the detected acceleration level of the boom is less than a minimum level during an attempt to raise the boom.

  • Patent number: 7894962
    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 angle of a boom with respect to a support near the first end. An attachment is coupled to the second end of the boom. A second sensor detects an attachment angle of attachment with respect to the boom. A second cylinder is associated with the attachment. A switch accepts a command to enter a ready position state from another position state. A controller controls 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 a target attachment angular range associated with the ready position state in response to the command.

  • Patent number: 7853384
    Abstract: A method and system for controlling a vehicle comprises a torque detector for detecting a first torque level and a second torque level applied to at least one wheel of the vehicle. The first torque level is associated with a lower boom position of a boom and a second torque level is associated with an elevated boom position higher than the lower boom position. A first hydraulic cylinder is capable of raising a boom from the lower boom position to raise an available torque from the first torque level. A second hydraulic cylinder is adapted to upwardly rotate or curl a bucket associated with the vehicle when the detected second torque level meets or exceeds a second torque threshold, for example.
