  • Patent number: 11124942
    Abstract: A system for controlling a ground engaging work implement includes a machine position sensor, a work surface position sensor, a work implement position sensor, and a controller. The controller determines the position of the machine, determines the topography of the work surface, determines a location of a pre-task trigger location adjacent the task start location, and determine a position of the lowest surface of the ground engaging work implement. The controller generates traverse signals to propel the machine from the task end location towards the task start location, generate work implement height signals to maintain the lowest surface of the ground engaging work implement at or above the traversing threshold height as the machine travels from the task end location towards the task start location, and generate work implement lowering signals to lower the work implement to the pre-task threshold height after the machine passes the pre-task trigger location.

  • Publication number: 20200392696
    Abstract: A method for operating an implement of a work machine is disclosed. The method includes detecting a progression of an input device between a first position and a second position based on a first parameter and a second parameter; determining a plurality of segments of the progression; estimating a value of the second parameter of at least one first segment and at least one second segment; issuing a baseline signal to generate command to initiate manipulation of the implement if the value of the second parameter of the first segment complies with corresponding second parameter threshold condition; issuing a secondary signal to continue manipulation of the implement if the value of the second parameter of the second segment complies with corresponding second parameter threshold condition; and terminating the command if the value of the second parameter of at least one second segment violates the corresponding second parameter threshold condition.
