  • System and method for positioning implement of machine
    Patent number: 9752300
    Abstract: A system associated with an implement of a machine is provided. The system includes a plane determination module configured to determine a track plane based on a relationship between at least two tracks of the machine. The system also includes an implement control module. The implement control module is configured to compute a location of two or more blade tip points of the implement of the machine in three dimensional space based on at least one constraint of a geometry of the implement. The implement control module is also configured to determine a blade tip point plane based on a relationship between at least two blade tip points of the implement. The implement control module is further configured to compare the blade tip point plane with the track plane and determine if the blade tip point plane is parallel to the track plane based on the comparison.
