  • Publication number: 20240353837
    Abstract: A system and method for responding to objects encountered by autonomous machines at a worksite. Sensors at the worksite gather sensor data that may be used by one or more processors to identify an object or obstacle at the worksite and an associated location. The sensors may be disposed on an autonomous machine operating at the worksite. The system and method include determining, based on the sensor data, an object classification for the object and/or obstacle and determining, based on the object classification and the sensor data, a remediation procedure to remove the object from the path and enable the autonomous machine to complete the work plan. The system and method further include determining a second machine included in the remediation procedure from a set of machines located at the worksite and causing the second machine to perform the remediation procedure.

  • Patent number: 11997561
    Abstract: A method includes receiving information indicative of a perimeter of a first portion of a work surface, generating, based on the information, a first geofence substantially overlaying the perimeter, and causing a display to display the first geofence. The method also includes receiving a first input indicating an accuracy of the first geofence. The method further includes determining that at least part of the first geofence is less than a threshold distance from a second geofence associated with the work surface. The method also includes generating, based on determining that the at least part of the first geofence is less than the threshold distance from the second geofence, a third geofence associated with the work surface.

  • Patent number: 11868114
    Abstract: A controller may configure the machine to operate in a plurality of modes including a manned control mode, a remote control mode, and an autonomous control mode. The controller may receive a request to cause the machine to perform an action; and determine a requested mode of operation of the machine associated with the request. The requested mode of operation may be one of the plurality of modes. The controller may selectively deny the request or enable the machine to perform the action based on a priority assigned to a current mode of operation of the machine and a priority assigned to the requested mode of operation.

  • Publication number: 20230383496
    Abstract: A method of identifying blade penetration that is ineffectual by a blade-based machine at a work site, including: attempting to cut an area of ground by the blade-based machine at the work site; determining that the cut is ineffectual based on a determination of a threshold cut volume achieved by the blade-based machine, the threshold cut volume being based on input from one or more position sensors on the blade-based machine; and initiating one or more remedial actions based on the determination of ineffectual cutting by the blade-based machine.

  • Patent number: 10843575
    Abstract: A control system for controlling operation of a drive motor includes an input device for providing a command signal that is indicative of a desired speed and direction of rotation of the drive motor. A sensor is associated with the drive motor and adapted to provide a sensor signal indicative of current rotational speed of the drive motor. A controller receives the command signal, and determine whether the command signal is indicative of a desired zero speed to be associated with the drive motor. The controller also receives the sensor signal, and determine whether the current rotational speed of the drive motor is within a pre-defined range of difference from the desired zero speed. The controller then generates a de-rated torque command signal having a reduced gain factor, and reduce the current rotational speed of the drive motor based on the de-rated torque command signal.

  • Patent number: 10808641
    Abstract: A method for testing power of an electric drive system includes setting the electric motor of the electric drive system to a desired speed and applying a brake load to the system. The method also includes increasing the brake load until an engine of the electric drive system is fully loaded. After the engine is fully loaded, the method includes maintaining the brake load until the acceleration remains between the upper predetermined threshold and the lower predetermined threshold for the predetermined period of time, which indicates that the engine has stabilized at full power. Once the engine is at full power, the commanded power of the electric drive system required for stabilizing the engine at full power is averaged, and the average power is compared to a predetermined pass/fail threshold to determine if the electric drive system has sufficient power.

  • Patent number: 10666182
    Abstract: A control system for a rotary electric machine includes a controller configured to generate dynamic input current data based upon a dynamic analysis of self flux data, mutual flux data, and saturation scaling factor data. Upon generating a torque request, the controller is configured to determine a desired electrical input based upon the dynamic input current data to generate the desired output torque. The desired electrical input includes a magnitude and duration of an electrical pulse and a desired angular position of the rotor of the rotary electric machine relative to the stator of the machine. The controller determines an angular position of the rotor and generates an operating command to generate the desired electrical input at the desired angular position of the rotor to propel the rotary electric machine and generate the desired output torque. A rotary electric machine and method of operating same are provided.
