Abstract
An example work machine control system includes target fill level determination logic configured to determine a target fill level for a container of an earth-moving work machine, fill level measurement logic configured to receive a sensor signal from a sensor that detects contents of the container and generate a measurement metric indicative of a current fill level of the container based on the sensor signal, and control logic configured to generate a machine control signal based on the measurement metric and the target fill level.
Claims20
A work machine control system comprising:
- target fill level determination logic configured to determine a target fill level for a container of an earth-moving work machine;
- fill level measurement logic configured to:
- receive a sensor signal from a sensor that detects contents of the container;
- and
- generate a measurement metric indicative of a current fill level of the container based on the sensor signal;
- and
- control logic configured to generate a machine control signal based on the measurement metric and the target fill level.
A computer-implemented method for controlling an earth-moving work machine, the method comprising:
- determining a target fill level for a container of the earth-moving work machine;
- receiving a sensor signal from a sensor that detects contents of the container;
- generating a measurement metric indicative of a current fill level of the container;
- and
- generating a machine control signal that controls the earth-moving work machine based on the measurement metric and the target fill level.
A work machine system comprising:
- an earth scraper machine comprising:
- a blade that is movable to adjust a dig depth into a terrain during a dig cycle;
- a container configured to receive earth material from the blade;
- and
- an imaging sensor configured to optically detect the earth material in the container;
- a traction unit configured to propel the earth scraper machine across the terrain;
- and
- a control system configured to:
- determine a target fill level for the container;
- receive a sensor signal from the imaging sensor;
- and
- generate a measurement metric indicative of a current fill level of the container based on the sensor signal;
- and
- control the dig cycle of the earth scraper machine based on the measurement metric and the target fill level.
