Abstract
A system for controlling a fan in a vehicle having a heat exchanger may include defining first and second geographic areas and determining a geographic location of the vehicle. A processor may be programmed to send a signal to operate the fan in a first rotational direction to move air through the heat exchanger in a first direction, and to send a signal to the fan to operate it in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in a second direction opposite the first direction when a plurality of conditions are met.
Claims20
A control system for a vehicle having a heat exchanger and a fan operable to move air through the heat exchanger, the control system comprising:
- a positioning system operable to determine a geographic location of the vehicle;
- and
- a processor in communication with the positioning system, at least one of the processor or the positioning system being programmed with a defined first geographic area and with at least one other defined geographic area, the processor being configured to send a signal to the fan to operate the fan in a first rotational direction to move air through the heat exchanger in a first direction, and to send a signal to the fan to operate the fan in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in a second direction opposite the first direction when a plurality of conditions are met, the conditions including the vehicle having entered at least one of the at least one other defined geographic area and thereafter having entered the first geographic area.
A control system for a vehicle having a heat exchanger and a fan operable to move air through the heat exchanger, the control system comprising:
- a positioning system operable to determine a geographic location of the vehicle;
- and
- a processor in communication with the positioning system, at least one of the processor or the positioning system being programmed with a first geographic area and a second geographic area, the processor being configured to:
- send a signal to the fan to operate the fan in a first rotational direction to move air through the heat exchanger in a first direction based on a first vehicle operating state, and
- send a signal to the fan to operate the fan in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in a second direction opposite the first direction based on a second vehicle operating state that includes the vehicle having entered the second geographic area and thereafter having entered the first geographic area.
A control system for a vehicle having a heat exchanger and a fan operable to move air through the heat exchanger, the control system comprising:
- a positioning system operable to determine a geographic location of the vehicle;
- and
- a processor in communication with the positioning system, at least one of the processor or the positioning system being programmed with a defined first geographic area and a defined second geographic area, the processor being configured to facilitate operation of the fan in a first rotational direction to move air through the heat exchanger in a first direction, and to facilitate operation of the fan in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in a second direction opposite the first direction when predetermined conditions are met, the predetermined conditions including having entered the second geographic area and thereafter having entered the first geographic area.
