Abstract
A mobile work machine includes a frame, a material loading system having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the material receiving area relative to the frame, and a control system configured to receive an indication of a detected object, determine a location of the object relative to the material loading system, and generate a control signal that controls the mobile work machine based on the determined location.
Claims19
A mobile work machine comprising:
- a frame;
- a material loading system comprising:
- a movable component having a material receiving area configured to receive material;
- and
- an actuator configured to control the material loading system to move the movable component relative to the frame;
- and
- a control system configured to:
- receive an indication of a detected object;
- determine a location of the detected object relative to the material loading system;
- define a threshold distance based on an object type of the detected object;
- define a maximum height limit position for the movable component relative to the frame based on:
- the location of the detected object, and
- the threshold distance;
- receive an indication of a commanded movement of the actuator to move the movable component to a target position;
- determine a probability that the commanded movement results in the movable component exceeding the maximum height limit position;
- and
- generate a control signal that controls the actuator based on the probability.
A computer-implemented method of controlling a mobile work machine, the computer-implemented method comprising:
- receiving an indication of a detected object on a worksite;
- determining a location of the detected object relative to a material loading system of the mobile work machine, the material loading system comprising a movable component having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the movable component relative to the frame;
- receiving an indication of a commanded movement of the actuator to move the movable component to a target position;
- determining a threshold distance based on an object type of the detected object;
- defining a maximum height limit position for the movable component relative to the frame based on:
- the determined location of the detected object, and
- the threshold distance;
- generating an indication that the commanded movement results will result in the movable component exceeding the maximum height limit position;
- and
- generating a control signal that controls the actuator based on the indication.
A control system for a mobile work machine, the control system comprising:
- an object detection system configured to:
- receive a signal from an object detection sensor and to detect an object based on the signal;
- determine a location of the object relative to a material loading system of the mobile work machine, the material loading system having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the material receiving area relative to the frame;
- and
- determine a threshold distance between the material loading system and the object based on an object type of the object;
- collision logic configured to:
- receive a commanded movement from an operator;
- and
- determine that the commanded movement will exceed the threshold distance;
- and
- control logic configured to generate a control signal based on the determination.
