| 发明名称 | Implement position control system having automatic calibration | ||
| 摘要 | A method, system, and non-transitory computer-readable storage medium for calibrating an implement actuation sensor of a machine are disclosed. The method may include calculating a first elevation value of an implement of the machine in a gravity reference frame of the machine. The method may further include calculating a second elevation value of a ground-engaging device of the machine in the gravity reference frame of the machine. The method may further include determining a difference between the first elevation value and the second elevation value. The method may further include calibrating the implement actuation sensor based on the determined difference. | ||

| 主权项 | 1. A method for calibrating an implement actuation sensor of a machine, comprising: calculating a first elevation value of an implement of the machine in a gravity coordinate frame of the machine when an implement cutting edge of the implement is at an elevation calculation location on an axis of the gravity coordinate frame; calculating a second elevation value of a ground-engaging device of the machine in the gravity coordinate frame of the machine when a predetermined point on the ground engaging device is at the elevation calculation location on the axis of the gravity coordinate frame; determining a difference between the first elevation value and the second elevation value; and calibrating the implement actuation sensor based on the determined difference. | ||
