COOLING CONTROL SYSTEM FOR A MOBILE MACHINE

摘要

A cooling control system is provided for a mobile machine having an engine. The cooling control system may have a circuit fluidly connected to the engine, and a heat exchanger configured to dissipate heat from coolant in the circuit. The cooling control system may also have a fan disposed proximate the heat exchanger, a thermostat configured to selectively allow coolant through the heat exchanger, and a locating device configured to generate a location signal indicative of a location of the mobile machine. The cooling control system may further have a pressure sensor configured to generate a pressure signal indicative of a barometric pressure in proximity to the mobile machine, and a controller in communication with the fan, the thermostat, the locating device, and the pressure sensor. The controller may be configured to selectively activate the fan and cause the thermostat to move to an increased cooling position when the location signal indicates the mobile machine is within a threshold area of a geological feature known to increase a temperature of the engine, and to selectively activate the fan and cause the thermostat to move based on the pressure signal when the location signal from the locating device is unavailable.

1. A cooling control system for a mobile machine having an engine, the cooling control system comprising:
a circuit fluidly connected to the engine; a heat exchanger configured to dissipate heat from coolant in the circuit; a fan disposed proximate the heat exchanger; a thermostat configured to selectively allow coolant through the heat exchanger; a locating device configured to generate a location signal indicative of a location of the mobile machine; a pressure sensor configured to generate a pressure signal indicative of a barometric pressure in proximity to the mobile machine; and a controller in communication with the fan, the thermostat, the locating device, and the pressure sensor, the controller being configured to:
selectively activate the fan and cause the thermostat to move to an increased cooling position when the location signal indicates the mobile machine is within a threshold area of a geological feature known to increase a temperature of the engine; andselectively activate the fan and cause the thermostat to move based on the pressure signal when the location signal from the locating device is unavailable.
