Dual sensor detection system with limited compute and method thereof

A method of detecting an object along a path of travel of a work machine, the work machine including a controller and a plurality of sensors, the plurality of sensors comprising at least a first low resolution sensing unit, a first high resolution sensing unit, a second low resolution sensing unit, a second high resolution sensing unit, a third low resolution sensing unit, and a third high resolution sensing unit, the method comprising:

• controlling the work machine as the work machine moves along the path of travel;
• receiving, via the controller, a first signal from the first low resolution sensing unit, a second signal from the second low resolution sensing unit, and a third signal from the third low resolution sensing unit;
• determining if any one of the first signal, second signal, and third signal is indicative of an object being detected by the respective low resolution sensing unit;
• if none of the first signal, second signal, and third signal is indicative of an object being detected, then assigning a first amount of throughput to the first high resolution sensing unit, a second amount of throughput to the second high resolution sensing unit, and a third amount of throughput to the third high resolution sensing unit;
• and
• if at least one of the first signal, second signal, and third signal is indicative of an object being detected, then assigning a fourth amount of throughput to the first high resolution sensing unit, a fifth amount of throughput to the second high resolution sensing unit, and a sixth amount of throughput to the third high resolution sensing unit.

A work machine configured to move along a path of travel, comprising:

• a frame;
• at least one ground-engaging mechanism for supporting the frame, the at least one ground-engaging mechanism configured to propel the work machine along the path of travel;
• a controller having a memory unit and a processor;
• a plurality of sensors disposed in communication with the controller, the plurality of sensors comprising a first low resolution sensing unit, a first high resolution sensing unit, a second low resolution sensing unit, a second high resolution sensing unit, a third low resolution sensing unit, and a third high resolution sensing unit, wherein the first low resolution sensing unit and the first high resolution sensing unit are located on one side of the work machine, the second low resolution sensing unit and the second high resolution sensing unit are located on a second side of the work machine, and the third low resolution sensing unit and the third high resolution sensing unit are located on a third side of the work machine;
• wherein, during operation of the work machine, the controller is configured to:
• receive a first signal from the first low resolution sensing unit, a second signal from the second low resolution sensing unit, and a third signal from the third low resolution sensing unit, wherein the first signal, second signal, and third signal are indicative of whether an object is detected by the respective low resolution sensing unit;
• compare a status of the first signal, the second signal, and the third signal to a threshold;
• determine, based on the status of the first signal, the second signal, and the third signal, an amount of throughput to assign to each of the first high resolution sensing unit, the second high resolution sensing unit, and the third high resolution sensing unit;
• and
• assign a first amount of throughput to the first high resolution sensing unit, a second amount of throughput to the second high resolution sensing unit, and a third amount of throughput to the third high resolution sensing unit.
