System and Method of Climate Control in Unmanned Machine

Abstract:

A controller-implemented system and method for automated control of a climate control system of a machine when being operated unmanned. The method includes utilizing at least one temperature sensor to determine the temperature of the machine cab, and, if the machine is being operated unmanned, generating signals to turn on the blower to a minimum setting, comparing the sensed temperature to at least one of minimum and maximum temperature thresholds, and generating signals to turn on the cab cooling device or cab heating device and adjusting the blower to maintain the cab temperature above the minimum and/or below the maximum temperature thresholds.
