1. A system for controlling movement of a machine, comprising:
- a drive system for causing movement of the machine;
a position sensor associated with the machine for generating position signals indicative of a position of the machine;
a communications system for transmitting signals between the machine and a remote system spaced from the machine; and
a controller configured to;
store an electronic map of a work site, the electronic map including a plurality of signal transmission thresholds corresponding to positions on the electronic map;
determine the position of the machine at the work site based upon the position signals;
receive the signals from the remote system;
determine a selected signal transmission threshold from the plurality of signal transmission thresholds based at least in part upon the position of the machine; and
generate a command signal to stop movement of the machine upon an interruption in signal transmission from the remote system exceeding the selected signal transmission threshold.

Abstract
A system for controlling movement of a machine includes a drive system, a position sensor, and a communications system. A controller is configured to determine the position of the machine and determine a signal transmission threshold based at least in part upon the position of the machine. The controller may stop movement of the machine upon an interruption in signal transmission from a remote system exceeding the signal transmission threshold.

13. A controller-implemented method for controlling movement of a machine, comprising:
-
storing an electronic map of a work site, the electronic map including a plurality of signal transmission thresholds corresponding to positions on the electronic map; determining a position of the machine at the work site based upon position signals from a position sensor associated with the machine; moving the machine; receiving signals from a remote system spaced from the machine; determining a selected signal transmission threshold from the plurality of signal transmission thresholds based at least in part upon the position of the machine; and generating a command signal to stop movement of the machine upon an interruption in signal transmission from the remote system exceeding the selected signal transmission threshold.

14. A system for controlling movement of a machine within a work site, comprising:
-
a drive system for causing movement of the machine; a position sensor associated with the machine for generating position signals indicative of a position of the machine; a communications system for transmitting signals between the machine and a remote system spaced from the machine; and a controller configured to; store an electronic map of the work site, the electronic map including a plurality of obstacles, each obstacle having an avoidance zone associated therewith; determine the position of the machine based upon the position signals; receive the signals from the remote system; determine a zone of interference associated with the machine; estimate a new position of the machine upon an interruption in signal transmission from the remote system to the machine; increase a size of one of the zone of interference and the avoidance zone upon the interruption in signal transmission from the remote system to the machine; and generate a command signal to stop movement of the machine if the zone of interference intersects with the avoidance zone. - View Dependent Claims (15, 16, 17, 18, 19, 20)
