Title: Device and method for co-operatively controlling work tool
Inventor: BRANDT EVERETT G
IPC: B66F9/24
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent fatigue of an operator from increasing by receiving a positional signal and a speed signal, determining an actual proceeding passage of a load engaging member and a proceeding passage of the load engaging member, and modifying a desired angular velocity and a desired linear speed according to the deviation between the proceeding passages. SOLUTION: A speed request is converted to a proceeding passage of a load engaging member 180 by a control box, and actual angular velocity and linear speed are converted to an actual proceeding passage of the load engaging member 180. The deviation between actual and desired proceeding passages and difference between actual and desired velocities are calculated by the control box, and compensation error is created. A speed command is converted to a speed ratio by the control box, and an actual speed command is converted to an actual speed ratio by the control box. The speed ratio vector is compared with an actual speed ratio vector by the control box to crease an error. The error value is used for modifying the ratio of the angular velocity to the linear speed. Thus, fatigue of an operator is reduced, and efficiency can be improved.
