Abstract
The present disclosure relates to a system for controlling an air flow rate into a vehicle engine room. The system includes: an air intake port receiving an exterior air at a front portion of the vehicle and supplying the air into the engine room; air ducts formed at both sides of the air intake port and introduce the exterior air into a wheel side in order to improve aerodynamic characteristic; a control valve configured to selectively convey the air flowed in the air intake port into the air ducts; a radiator disposed between the air intake port and the engine room; and a control portion configured to control the control valve based on an operating state of vehicle. The air ducts are selectively communicated with the air intake port and disposed at upstream of the radiator.
Claims20
A system for controlling an air flow into a vehicle engine room, the system comprising:
- an air intake port configured to receive an exterior air at a front portion of a vehicle and supply the exterior air into the engine room;
- air ducts formed at both sides of the air intake port and configured to introduce the exterior air into a wheel side so as to improve aerodynamic characteristic;
- a control valve configured to selectively convey the exterior air flowed in the air intake port into the air ducts;
- a radiator disposed between the air intake port and the engine room;
- and
- a control unit configured to control the control valve based on an operating state of the vehicle,
- wherein the air ducts are selectively communicated with the air intake port and are disposed upstream of the radiator.
A control method of a system for controlling an air flow into a vehicle engine room, the system comprising:
- an atmospheric temperature sensor configured to measure an atmospheric temperature;
- a speed sensor configured to measure a vehicle speed;
- an air conditioning pressure sensor configured to measure air conditioning internal pressure;
- an air conditioning switch sensor configured to measure an operational signal of an air conditioning switch;
- a refrigerant temperature sensor configured to measure a refrigerant temperature;
- a fan shroud in which a cooling fan including a fan motor and a fan blade is mounted;
- a rotary shutter which is provided in the fan shroud while corresponding to an operation area of the fan blade, and in which an area through which air passes is varied in a circumferential direction;
- a position sensor configured to measure an open area of the rotary shutter;
- a plurality of flaps which are provided in the fan shroud, and open and close a part of a portion where the rotary shutter is not mounted;
- an air intake port receiving an exterior air at a front portion of a vehicle and supplying the exterior air into the engine room;
- air ducts formed at both sides of the air intake port and configured to introduce the exterior air into a wheel side;
- and
- a control valve configured to selectively convey the air flowed in the air intake port into the air ducts;
- and
- a control unit configured to control an open area of the rotary shutter, operations of opening and closing the plurality of flaps, an operation of the cooling fan, and an operation of the control valve based on an operating state of the vehicle,
- the method comprising:
- determining, by the control unit, the operating state of the vehicle based on sensor signals from the atmospheric temperature sensor, the speed sensor, the air conditioning pressure sensor, the air conditioning switch sensor, the refrigerant temperature sensor, and the position sensor;
- and
- determining whether to close or open the rotary shutter based on the determined operating state of the vehicle;
- and
- fully closing, by the control unit, the rotary shutter, and when the rotary shutter is fully closed, closing the plurality of flaps, turning off the operation of the cooling fan, and turning on the operation of the control valve.
