  • Patent number: 10228232
    Abstract: A system having a controller is provided. The controller receives a signal indicative of an actual position and an actual orientation of a machine on a worksite, from a position detection module. The controller determines a first view of the machine on the worksite. The first view shows the actual position of the machine and a target position of the machine. A path is determined between the first and the second indicator. The controller determines a view of the machine on the worksite. The view has a first and a second indicator. The first indicator is indicative of the actual position and the actual orientation of the machine. The second indicator is indicative of the target position and a target orientation of the machine and includes a target circle. The controller displays the view based, at least in part, on the actual position of the machine relative to the target position on a display unit.

  • Patent number: 9945100
    Abstract: A positioning system for a machine is disclosed. The positioning system includes a satellite positioning unit to generate signals indicative of a location of the machine in a worksite and an inertial measurement unit (IMU) to generate signals indicative of a position of the machine. A controller is communicated with the satellite positioning unit and the IMU. The controller determines a first error value associated with a location of the machine based on signals received from the satellite positioning unit. The controller further determines a second error value associated with a location and a position of the machine based on signals received from the satellite positioning unit and signals received from the IMU, respectively. Further, a location of the machine is determined based on signals received from the satellite positioning unit and the IMU if the first error value is less than the second error value.

  • Patent number: 9773175
    Abstract: A system for tracking a position of a cable attached between a power source and a machine in a worksite is disclosed. The cable is further coupled to a guiding device located in the worksite between the power source and the machine. The system includes a perception module disposed on the machine to detect a location of the guiding device. The system further includes a controller disposed to be in communication with the perception module. The controller determines the location of the guiding device with respect to a location of the machine and determines a distance between the guiding device and the machine.

  • Patent number: 9529092
    Abstract: A method for detecting and mitigating errors in a positioning system includes receiving a first signal from a global navigation satellite system (GNSS) indicative of a first position and a second signal from the GNSS indicative of a second position of a machine, determining a difference between the first position and the second position, detecting an error in a current position of the machine when the difference between the first and the second position exceeds a threshold of one of (a) a maximum distance given a maximum velocity, and (b) an actual distance determined based on an output of an inertial sensor on the machine, and mitigating the detected error in the current position of the machine by switching from an output of the positioning system to a position output determined based upon the output of the inertial sensor to update the current position.
