OBJECT DETECTION SYSTEM HAVING INTERFERENCE AVOIDANCE STRATEGY
First Claim
1. An object detection system for a first machine, comprising:
- at least one transmitter configured to generate a laser beam directed onto a ground surface in proximity to the first machine;
a receiver configured to detect the laser beam and generate a corresponding signal; and
a controller in communication with the at least one transmitter and the receiver, the controller being configured to;
generate an electronic terrain map based on the signal;
make a determination that a second machine is operating within a range of the first machine; and
adjust operation of the at least one transmitter and receiver based on the determination to reduce undesired interactions caused by operation of the second machine.

Abstract
An object detection system for a first machine is disclosed. The object detection system may have at least one transmitter configured to generate a laser beam directed onto a ground surface in proximity to the first machine, and a receiver configured to detect the laser beam and generate a corresponding signal. The object detection system may also have a controller in communication with the at least one transmitter and the receiver. The controller may be configured to generate an electronic terrain map based on the signal. The controller may also be configured to make a determination that a second machine is operating within a range of the first machine, and to adjust operation of the at least one transmitter and receiver based on the determination to reduce undesired interactions caused by operation of the second machine.

10. A computer readable medium having computer executable instructions for performing a method of object detection for a first mobile machine, the method comprising:
-
directing at least a first laser beam onto a ground surface; detecting the at least a first laser beam and responsively generating an electronic terrain map based on the detection; making a determination that a second mobile machine is operating within a range of the first mobile machine; and adjusting characteristics of the at least a first laser beam based on the determination to reduce undesired interactions caused by the second mobile machine. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A machine, comprising:
-
a body; a plurality of traction devices configured to support the body and propel the machine; a first array of laser beam transmitters mounted to an end of the body and configured to generate a first plurality of grid lines on a ground surface in a travel path of the machine; a second array of laser beam transmitters mounted to an end of the body apart from the first array of laser beam transmitters and configured to generate a second plurality of grid lines on the ground surface in the travel path of the machine and produce a plurality of intersections with the first plurality of grid lines; a receiver configured to detect the plurality of intersections and generate a signal based on the detection; and a controller in communication with the first and second arrays of laser beam transmitters and with the receiver, the controller being configured to; generate an electronic terrain map based on the signal; make a determination that a second machine is operating within a range of the first machine; and adjust at least one of a wavelength and a pulsation frequency of laser beams generated by the first and second arrays of transmitters and a corresponding operation of the receiver based on the determination to reduce undesired interactions with a laser beam originating from the second machine.
