  • the judging step judges at least one opening state of only a sun roof, or an opening state of only a rear window as an opening state during which the buffeting noise is generated.
  • the judging step further judges the speed of the vehicle is 40-60 kph in case of the opening state of only the sun roof, and the speed of the vehicle is 60-80 kph in case of the opening state of only the rear window as states in which buffeting noise is generated.
  • FIG. 1 and FIG. 2 are drawings showing a buffeting noise reducing system in a vehicle according to an embodiment of the present invention.

  • the air intake 12 is provided with a cover of a mesh type to prevent foreign objects from being introduced into the duct 10 .
  • the duct 10 is connected to the blower assembly 20 at its other end for discharging the inside air to outside, and the blower assembly 20 is disposed at the lower side of the back of the vehicle, for example at the trunk.
  • the blower assembly 20 includes a housing 22 defining an air chamber, a blower fan 24 provided inside the housing 22 , a blower motor 26 that drives the blower fan 24 , and an air outlet 23 .
  • a 400 W blower motor may be used.
  • An opening/closing plate 28 is provided in the air outlet 23 , and an actuator 29 adjusts the degree of opening of the opening/closing plate 28 .
  • a speed sensor 33 detects a vehicle speed.
  • the system also includes a wind inflow port opening detection unit 34 and a control unit 30 , which may comprise a processor, memory, and associated hardware, software, and/or firmware as may be selected and programmed by a person of ordinary skill in the art based on the teachings herein.
  • the wind inflow port opening detection unit 34 detects an opening state of the wind inflow ports, such as the sun roof 2 and rear window 4 .
  • the wind inflow port opening detection unit 34 may include a sensor provided at the wind inflow port. Alternatively, it may include a switch detection sensor which detects an operation of the sun roof or window switch (i.e. the switch operated by the user to open or close the window or sunroof). Alternatively, it may include an actuator detection sensor which detects operation of an actuator for driving the window or the sun roof.
  • the wind inflow port opening detection unit 34 detects a single wind inflow port opening state, e.g. only the sun roof is opened while the other inflow ports are closed.
  • the control unit 30 receives opening information from the wind inflow port opening detection unit 34 , detects a speed of the vehicle by information transmitted from the speed sensor 32 , and controls the operation of the blower motor 26 and the actuator 29 .
  • the duct 10 may be connected to a cooling path 15 for cooling the battery 5 so that the battery 5 may be cooled by the inside air of a vehicle introduced into the duct 10 .
  • the air is introduced into the cooling path 15 , and then is introduced into the blower housing 22 , and subsequently is discharged to via the air outlet 23 .
  • a buffeting noise of a vehicle depends on the volume and layout of the passenger compartment and in light of these factors, if only the sun roof 2 is opened, the buffeting noise is generated when a speed of a vehicle is 40-60 kph, and if only one rear window 4 is opened, the buffeting noise is generated when the speed is 60-80 kph.
  • the buffeting noise reducing method comprises an opening detection step S 10 of a wind inflow port; a speed detection step S 20 ; a judging step S 30 for judging whether the detected state belongs to a state that a buffeting noise is generated, and a blower driving step S 40 .

  • vehicle speed is sensed by the speed sensor 32 .
  • the speed sensor 32 provides the information to the control unit 30 .
  • the control unit 30 judges whether the detected state is a state in which buffeting noise is generated.
  • a database related to the opening state of a wind inflow port and the speed of a vehicle corresponding to the opening state is provided to the control unit 30 as a pre-set information.
  • the control unit 30 judges the detected state as a buffeting noise state if only the sun roof 2 is opened, and the speed is 40-60 kph. Further, the control unit 30 judges the detected state as a buffeting noise state if only a rear window 4 of is opened, and the speed is 60-80 kph.
  • the blower driving step S 40 is executed.
  • the control unit 30 provides a driving signal to the blower motor 26 , and thereby the inside air of a vehicle is discharged.

  • a buffeting noise reducing system and method in a vehicle of the present invention when the blower is not operated, it is possible to adjust the degree of opening of the opening/closing plate to correspond to the speed of the vehicle so that the inhaling and discharging sound (the noise generated when inflow and outflow of air are generated due to the difference of pressure between the indoors and the outdoors during driving) may be reduced.
  • FIG. 6 illustrates another exemplary embodiment of the present invention comprising a step for reducing the inhaling and discharging sound
  • step S 40 If the detected state is a state in which buffeting noise is generated, the blower driving step S 40 is executed, and if the detected state is not a state in which buffeting noise is generated, step S 50 for adjusting the degree of opening of the opening/closing plate 28 is executed for reducing the inhaled and discharged sound.
