  • System and method for controlling implement orientation of a work vehicle based on a modified error value
    Patent number: 11821169
    Abstract: A system for controlling implement orientation of a work vehicle includes a computing system configured to control an operation of a lift actuator of the vehicle such that an implement of the vehicle is moved from a first vertical position relative to a second vertical position. Furthermore, the computing system is configured to monitor the angle of the implement as the implement is moved from the first vertical position to the second vertical position. Additionally, the computing system is configured to determine an actual error value between the monitored angle and a selected angle of the implement. Moreover, the computing system is configured to determine a modified error value that is different than the actual error value and control an operation of a tilt actuator of the vehicle to adjust the angle of the implement relative to the driving surface based on the modified error value.
