Description

[Technical Field]

[0001] The present invention relates to a wind deflector device provided on a sunroof of a vehicle. [Background technology]

[0002] Conventionally, some vehicles, such as automobiles, are equipped with a sunroof on the roof of the upper part of the vehicle body. In this type of vehicle, the roof opening formed in the roof can be opened or closed by the occupant operating a switch or the like.

[0003] When a vehicle is driven with the roof opening open, a low-frequency noise called wind slump occurs at low vehicle speeds. To suppress this wind slump, vehicles are generally equipped with a wind deflector. The wind deflector stands up when the roof opening is open, thereby suppressing the intrusion of vortex air from the vehicle cabin and suppressing the generation of wind slump.

[0004] On the other hand, when the wind deflector is raised, it can cause wind noise when the vehicle is traveling at high speeds. In particular, when an opening or the like is formed in the wind deflector in order to effectively suppress wind throb, the generation of wind noise becomes noticeable.

[0005] In response to this, for example, Patent Document 1 discloses a wind deflector device equipped with a mechanism for opening and closing the openings of the wind deflector. This wind deflector device opens all of the through-holes at low to medium vehicle speeds, and closes all of the through-holes with shutters at high vehicle speeds, thereby achieving both suppression of wind throb and suppression of wind noise.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-276574 Summary of the Invention [Problem to be solved by the invention]

[0007] However, a vehicle in motion is affected by various natural winds in addition to the wind generated by the vehicle while it is moving. Therefore, with a configuration that simply opens and closes the through-holes depending on the vehicle speed range while the vehicle is moving, as in the technology disclosed in Patent Document 1, it may be difficult to effectively suppress the occurrence of wind throbbing and wind noise.

[0008] The present invention has been made in view of the above circumstances, and has an object to provide a wind deflector device that can more effectively achieve both suppression of wind throb and suppression of wind noise. [Means for solving the problem]

[0009] A wind deflector device according to one aspect of the present invention comprises a deflector panel provided in front of a roof opening and capable of rising and falling relative to the vehicle body, a plurality of ventilation openings provided in the deflector panel along the vehicle width direction, a plurality of shutters capable of opening and closing each of the plurality of ventilation openings independently, a wind detection means for detecting wind speed and wind direction, and a deflector control means for controlling the rising and falling of the deflector panel and the opening and closing of the plurality of ventilation openings by the plurality of shutters according to the wind speed and the wind direction, wherein when the wind detection means detects wind including a crosswind component, the deflector control means changes the opening state of the plurality of ventilation openings by the plurality of shutters. [Effects of the Invention]

[0010] According to the wind deflector device of the present invention, it is possible to more effectively achieve both suppression of wind throbbing and suppression of wind noise. [Brief explanation of the drawings]

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, in which: Figure 1 is a perspective view showing an upper part of a vehicle body according to one embodiment of the present invention;

[0013] As shown in Fig. 1, a vehicle (host vehicle) 1 has a roof panel 3 on the top of a vehicle body 2. A sunroof device 5 is provided on the roof panel 3.

[0014] The sunroof device 5 has a roof opening 10 formed in the roof panel 3, a movable roof panel 11 for opening and closing the roof opening 10, a wind deflector device 12 that can be raised and lowered at the front edge of the roof opening 10, and a vehicle integrated control unit (hereinafter referred to as integrated_ECU) 13.

[0015] The roof opening 10 is configured, for example, as a rectangular hole that connects the outside of the vehicle with the interior of the vehicle. Guide rails 15 that protrude into the inside of the roof opening 10 are provided on the left and right sides of the roof opening 10 (see FIGS. 5 to 9). The guide rails 15 guide the movable roof panel 11 when the roof opening 10 is opened or closed.

[0016] The movable roof panel 11 is made of, for example, a rectangular glass plate. A panel motor 20 built into the roof panel 3 is connected to the movable roof panel 11 via a panel drive mechanism (not shown).

[0017] As a result, the movable roof panel 11 is configured to be able to move back and forth steplessly along the guide rails 15 between an advanced position (see Figure 1) in which it blocks the roof opening 10 and a retracted position (see Figures 5 to 9) in which it is housed inside the roof panel 3.

[0018] A resin seal member 21 is provided on the outer periphery of the movable roof panel 11. This allows the movable roof panel 11 to liquid-tightly close the roof opening 10 when it reaches the extended position.

[0019] The wind deflector device 12 has a deflector panel 25. In this embodiment, the deflector panel 25 is divided into two parts, a left panel member 25l and a right panel member 25r, along the vehicle width direction. The deflector panel 25 can be divided into three or more panel members, or can be formed as a single panel member.

[0020] As shown in FIGS. 2 and 3, the left panel member 25l is pivotally connected to the inside of the front edge of the roof opening 10 via a plurality of hinges 26 (only one is shown).

[0021] Furthermore, the tip of a deflector link 27 is rotatably connected to the left end of the left panel member 25l.

[0022] A rack gear 271a is formed on the base end side of the deflector link 271 inside the roof panel 3. A left deflector motor 281 built into the roof panel 3 is connected to this rack gear 271a via a worm gear 281a.

[0023] By driving the left deflector motor 28l, the left panel member 25l can be continuously displaced between an upright position (see, for example, Figure 5) in which it protrudes above the roof panel 3 from the roof opening 10 and a collapsed position (see Figure 1) in which it is accommodated inside the roof opening 10.

[0024] When the left side panel member 25l is in the collapsed position, it is positioned lower than the movable roof panel 11. As a result, when the movable roof panel 11 is in the extended position, the left side panel member 25l is covered by the movable roof panel 11 inside the roof opening 10.

[0025] Furthermore, a ventilation opening 29l is formed in the middle of the left panel member 25l in the vehicle width direction. The ventilation opening 29l can be opened and closed by a shutter 30l. The shutter 30l is housed in the internal space of the left panel member 25l.

[0026] Furthermore, on the rear surface side of the left panel member 25l, one end (right end) of a key groove 31l extending in the vehicle width direction is in communication with the ventilation opening 29l. A key 32l protruding rearward from the rear surface side of the shutter 30l is engaged with the key groove 31l.

[0027] A rack gear 33l extending toward the other end in the vehicle width direction is connected to the key 32l. A left shutter motor 34l is connected to the rack gear 33l via a worm gear 34la.

[0028] By driving the left shutter motor 34l, the shutter 30l can be displaced continuously between a closed position (see FIG. 2) in which the ventilation opening 29l is closed and an open position (see FIG. 3) in which the ventilation opening 29l is opened.

[0029] The transmission of the driving force of the left shutter motor 34l to the shutter 30l is not limited to a gear mechanism using the rack gear 33l and the worm gear 34l, but a well-known link mechanism can also be used.

[0030] In this embodiment, the left panel member 25l and the right panel member 25r are bilaterally symmetrical. Therefore, Figures 2 and 3 show only the main components of the left panel member 25l. Regarding the components of the right panel member 25r, the "left (l)" in the above-described components should be read as "right (r)," and a description thereof will be omitted.

[0031] The integrated_ECU 13 controls the opening and closing of the movable roof panel 11, the raising and lowering of the left and right panel members 25l and 25r, and the opening and closing of the left and right shutters 30l and 30r.

[0032] To realize these controls, for example, as shown in FIG. 4, the integrated_ECU 13 is connected to a panel open / close switch 40, a wind pressure sensor 41, and a microphone 42.

[0033] The panel opening / closing switch 40 is provided, for example, near the driver's seat inside the vehicle.

[0034] The wind pressure sensor 41 is composed of, for example, a plurality of pressure sensors. This wind pressure sensor 41 is provided, for example, on the front bumper. The wind pressure sensor 41 detects wind speed (wind pressure) and wind direction when each pressure sensor is pressed by wind pressure. In this way, the wind pressure sensor 41 corresponds to a specific example of wind detection means.

[0035] The microphone 42 is provided, for example, in the headrest of the seat. As a result, the microphone 42 detects noises similar to those heard by the passenger, such as wind throbbing and wind noise. In this way, the microphone 42 corresponds to one specific example of noise detection means.

[0036] Furthermore, the integrated_ECU 13 is connected to a driving control unit (driving_ECU 54) for managing driving assistance control of the vehicle 1.

[0037] In this embodiment, the travel_ECU 54 is incorporated into the camera unit 50. The camera unit 50 is configured to include a stereo camera 51, an image processing unit (IPU) 52, and an image recognition unit (image recognition_ECU) 53 in addition to the travel_ECU 54.

[0038] The stereo camera 51 has a main camera 51a and a sub-camera 51b. The main camera 51a and the sub-camera 51b are configured with, for example, a CMOS, and are arranged symmetrically on either side of the center in the vehicle width direction. The main camera 51a and the sub-camera 51b capture stereo images of the driving environment in the area ahead of the vehicle from different viewpoints at a predetermined imaging cycle that is synchronized with each other.

[0039] The IPU 52 processes the driving environment images captured by the stereo camera 51 in a predetermined manner to detect the edges of various objects, such as three-dimensional objects and road markings, displayed in the images. The IPU 52 then calculates distance information from the positional deviation of corresponding edges on the left and right images. As a result, the IPU 52 generates image information (distance image information) that includes distance information.

[0040] Based on distance image information received from the IPU 52, the image recognition_ECU 53 calculates the road curvature [1 / m] of the marking lines that separate the left and right lanes (the lane on which the vehicle 1 is traveling) and the width between the left and right marking lines (lane width). The image recognition_ECU 53 also calculates the road curvature and the width between the left and right marking lines of lanes adjacent to the lane on which the vehicle 1 is traveling. Various methods are known for calculating the road curvature and lane width. For example, the image recognition_ECU 13 recognizes the left and right marking lines by binarizing the road curvature based on the driving environment information using brightness differences, and calculates the curvature of the left and right marking lines for each predetermined section using a curve approximation formula based on the least squares method. Furthermore, the image recognition_ECU 53 calculates the lane width from the difference in curvature between the left and right marking lines.

[0041] Then, the image recognition_ECU 53 calculates the lane center and the lateral position deviation of the host vehicle 1 based on the curvature of the left and right lane markings and the lane width. Here, the lateral position deviation of the host vehicle 1 is the distance from the lane center to the center of the host vehicle 1 in the vehicle width direction.

[0042] The image recognition_ECU 53 also performs predetermined pattern matching on the distance image information, thereby recognizing three-dimensional objects such as guardrails, fences, curbs, and surrounding vehicles that extend along the road. Here, the image recognition_ECU 53 recognizes, for example, the type of the three-dimensional object, the distance to the three-dimensional object, the speed of the three-dimensional object, and the relative speed between the three-dimensional object and the vehicle 1.

[0043] The various pieces of information recognized by the image recognition_ECU 53 are output to the traveling_ECU 54 as traveling environment information.

[0044] In this manner, in this embodiment, the image recognition_ECU 53, together with the stereo camera 51 and the IPU 52, corresponds to a specific example of a driving environment recognition means that recognizes driving environment information outside the vehicle.

[0045] Furthermore, the travel_ECU 54 is connected with various sensors, such as a locator unit 56 and a vehicle speed sensor 57 as a vehicle speed detection means for detecting the vehicle speed V of the host vehicle 1.

[0046] The locator unit 56 includes a GNSS sensor 56a and a high-precision road map database (road map DB) 56b.

[0047] The GNSS sensor 56a receives positioning signals transmitted from a plurality of positioning satellites to determine the position (latitude, longitude, altitude, etc.) of the vehicle 1.

[0048] The road map DB 56b is a large-capacity storage medium such as an HDD. High-precision road map information (dynamic map) is stored in this road map DB 56b. The road map information includes, for example, lane data required for automated driving, such as lane width data, lane center position coordinate data, lane travel azimuth data, and speed limit data. Lane data is stored at intervals of several meters for each lane on the road map. Furthermore, the road map information stores information on road type (expressway, general road, etc.) and ground surface roughness classification (coastal area, rural area, general area, urban area, etc.).

[0049] For example, based on a request signal from the driving_ECU 54, the road map DB 56b outputs road map information of a set range based on the vehicle position measured by the GNSS sensor 56a to the driving_ECU 54 as driving environment information.

[0050] Thus, in this embodiment, the road map DB 56b, together with the GNSS sensor 56a, corresponds to a specific example of a driving environment recognition means that recognizes driving environment information outside the vehicle.

[0051] Furthermore, in addition to the integrated_ECU 13, various control units such as an engine control unit (E / G_ECU), a transmission control unit (T / M_ECU), a brake control unit (BK_ECU), and a power steering control unit (PS_ECU), which are not shown, are connected to the traveling_ECU 54 via an in-vehicle communication line such as a CAN (Controller Area Network).

[0052] The travel_ECU 54 then implements functions such as an adaptive cruise control (ACC) function and an active lane keep centering (ALKC) function through control of each ECU.

[0053] The integrated_ECU 13 controls the opening and closing of the movable roof panel 11 through drive control of the panel motor 20. That is, the integrated_ECU 13 controls the drive of the panel motor 20 in response to an operation signal when the panel opening / closing switch 40 is operated by an occupant. In this way, the integrated_ECU 13 controls the opening and closing of the movable roof panel 11.

[0054] The integrated_ECU 13 also controls the driving of the left and right deflector motors 28l and 28r, thereby controlling the raising and lowering of the left and right panel members 25l and 25r.

[0055] Furthermore, the integrated_ECU 13 controls the opening and closing of the left and right shutters 30l and 30r through drive control of the left and right shutter motors 34l and 34r.

[0056] Control of the left and right panel members 25l, 25r and the left and right shutters 30l, 30r is basically performed based on the wind speed and wind direction relative to the vehicle 1 detected by the wind pressure sensor 41. Note that, instead of the wind speed detected by the wind pressure sensor 41, it is also possible to use a wind speed (such as the wind speed of the wind while traveling) estimated based on the vehicle speed V. In this case, the vehicle speed sensor 57, together with the wind pressure sensor 41, corresponds to a specific example of wind detection means.

[0057] For example, when the wind speed is less than a set speed (e.g., 75 km / h) and the wind direction is ahead of the vehicle 1, the integrated_ECU 13 basically raises the left and right panel members 25l, 25r. Also, the integrated_ECU 13 basically opens the left and right ventilation openings 29l, 29r (see FIG. 5).

[0058] By raising the left and right panel members 25l, 25r, vortices generated along the roof panel 3 of the vehicle body 2 move along the left and right panel members 25l, 25r above the roof opening 10. This prevents the vortices from entering the vehicle cabin through the roof opening 10. In addition, by opening the left and right ventilation openings 29l, 29r, the vortices of the wind passing through the left and right ventilation openings 29l, 29r are straightened. The wind straightened by the left and right ventilation openings 29l, 29r passes near the roof opening 10, where the vortices prevent the vortices from entering the vehicle cabin through the roof opening 10. This effectively prevents wind slump, which is likely to occur when the wind speed is low. The control amount for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r can be continuously set according to the wind speed, etc.

[0059] However, for example, if the noise level due to wind noise is equal to or higher than a preset threshold, the integrated_ECU 13 appropriately corrects the control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r. For example, in order to suppress wind noise due to wind passing through the ventilation openings 29l, 29r, the integrated_ECU 13 closes the left and right ventilation openings 29l, 29r (see FIG. 6).

[0060] Furthermore, for example, when the wind speed is less than the set speed and the wind direction includes a component to the left of the vehicle 1, the integrated_ECU 13 basically raises the left panel member 25l located in the same direction as the wind direction and lowers the right panel member 25r located in the opposite direction to the wind direction. Furthermore, the integrated_ECU 13 basically opens the left ventilation opening 29l located in the same direction as the wind direction and closes the right ventilation opening 29r located in the opposite direction to the wind direction (see FIG. 7).

[0061] This is because, when the wind direction includes a component to the left of the vehicle 1, the distance the wind passes through the right area of ​​the roof opening 10 is shorter than the left area, and in the area to the right of the roof opening 10, there is little chance of a vortex flow entering the vehicle cabin. Therefore, wind throbbing, which is likely to occur when the wind speed is low, is suppressed, while wind noise is also more effectively suppressed. The control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r can be set continuously according to the wind speed and wind direction component.

[0062] However, for example, if the noise level due to wind noise is equal to or greater than a preset threshold, the integrated_ECU 13 appropriately corrects the control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r. For example, in order to suppress wind noise caused by wind passing through the ventilation opening 29l, the integrated_ECU 13 closes the left ventilation opening 29l.

[0063] Furthermore, for example, when the wind speed is less than a set speed and the wind direction includes a component to the right of the vehicle 1, the integrated_ECU 13 basically raises the right panel member 25r located in the same direction as the wind direction and lowers the left panel member 25l located in the opposite direction to the wind direction. Furthermore, the integrated_ECU 13 basically opens the right ventilation opening 29r located in the same direction as the wind direction and closes the left ventilation opening 29l located in the opposite direction to the wind direction (see FIG. 8).

[0064] This is because, when the wind direction includes a component to the right of the vehicle 1, the distance the wind passes through the roof opening 10 is shorter in the left area than in the right area, and in the area to the left of the roof opening 10, there is little chance of a vortex flow entering the vehicle cabin. Therefore, wind throbbing, which is likely to occur when the wind speed is low, is suppressed, while wind noise is also more effectively suppressed. The control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r can be set continuously according to the wind speed and wind direction component.

[0065] However, for example, if the noise level due to wind noise is equal to or greater than a preset threshold, the integrated_ECU 13 appropriately corrects the control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r. For example, in order to suppress wind noise caused by wind passing through the ventilation opening 29l, the integrated_ECU 13 closes the right ventilation opening 29r.

[0066] Furthermore, for example, when the wind speed is equal to or greater than a set speed and the wind direction is ahead of the vehicle 1, the integrated_ECU 13 basically lays down the left and right panel members 25l, 25r. Furthermore, the integrated_ECU 13 basically closes the left and right ventilation openings 29l, 29r (see FIG. 9).

[0067] This is because even if a vortex is generated when the wind speed is high, the vortex passes through the roof opening 10 before entering the vehicle interior through the roof opening 10. In addition, this is to suppress wind noise generated by the edges of the left and right panel members 25l, 25r and the left and right ventilation openings 29l, 29r. The control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r can be set continuously according to the wind speed and wind direction components.

[0068] However, for example, if the noise level due to wind throb is equal to or greater than a preset threshold, the integrated_ECU 13 appropriately corrects the control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r. For example, in order to suppress the intrusion of vortex currents into the vehicle interior through the roof opening 10, the integrated_ECU 13 corrects the left and right panel members 25l, 25r to the upright side by a predetermined amount.

[0069] Furthermore, for example, when the wind speed is equal to or greater than a set speed and the wind direction includes a component to the left of the vehicle 1, the integrated_ECU 13 basically raises the left panel member 25l positioned in the same direction as the wind direction and lowers the right panel member 25r positioned on the opposite side of the wind direction. The integrated_ECU 13 also closes the left and right ventilation openings 29l, 29r (see FIG. 10).

[0070] This is because when the wind direction includes a component to the left of the vehicle 1, the distance the wind passes through the roof opening 10 becomes longer in the left area, and even when the wind speed is high, there is a high possibility that vortex currents will enter the vehicle interior through the roof opening 10.

[0071] However, for example, if the noise level due to wind noise is equal to or greater than a preset threshold, the integrated_ECU 13 appropriately corrects the control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r. For example, in order to suppress wind noise caused by wind passing through the ventilation opening 29l, the integrated_ECU 13 corrects the left panel member 25l to the tilting side.

[0072] Furthermore, for example, when the wind speed is equal to or greater than a set speed and the wind direction includes a component to the right of the vehicle 1, the integrated_ECU 13 basically raises the right panel member 25r located in the same direction as the wind direction and lowers the left panel member 25l located on the opposite side to the wind direction. The integrated_ECU 13 also closes the left and right ventilation openings 29l, 29r (see FIG. 11).

[0073] This is because when the wind direction includes a component to the right of the vehicle 1, the distance the wind passes through the roof opening 10 becomes longer in the right-hand area, and even when the wind speed is high, there is a high possibility that vortex currents will enter the vehicle interior through the roof opening 10.

[0074] However, for example, if the noise level due to wind noise is equal to or greater than a preset threshold, the integrated_ECU 13 appropriately corrects the control amounts for the left and right panel members 25l, 25r and the left and right shutters 30l, 30r. For example, in order to suppress wind noise caused by wind passing through the ventilation opening 29l, the integrated_ECU 13 corrects the right panel member 25r to the tilting side.

[0075] Here, the correction of each of the control variables described above can also be performed based on, for example, driving environment information. That is, when the vehicle 1 is driving on a highway, the wind direction and the wind turbulence differ depending on whether the highway is an open area with no obstacles such as fences, a closed area surrounded by obstacles such as fences on both sides, a mixed area with an obstacle such as a fence on only one side, or whether the vehicle is inside a tunnel. Also, when the vehicle 1 is driving on an ordinary road, the wind direction and the wind turbulence differ depending on whether the ordinary road is in a coastal area, a rural area, an ordinary area, or an urban area.

[0076] Furthermore, if there is a preceding vehicle (vehicle in front) ahead of vehicle 1, the wind direction and wind turbulence will differ depending on whether the vehicle in front is a truck, a standard-sized car, a compact car, or a light car, and the distance between the vehicle and the vehicle in front.

[0077] Therefore, the integrated_ECU 13 can correct the control amount based on these conditions.

[0078] The integrated_ECU 13 can set the control amount and the correction amount based on each of the above-mentioned conditions by, for example, referring to a map or the like that is set in advance based on experiments, simulations, etc. As this map, for example, a map in which the control amount and the correction amount are set in advance for each combination of control conditions shown in Fig. 13 can be used.

[0079] Thus, in this embodiment, the integrated_ECU 13 corresponds to a specific example of a deflector control means.

[0080] Next, the control of the wind deflector device 12 will be described with reference to a flowchart of a deflector control routine shown in Fig. 12. This routine is repeatedly executed by the integrated_ECU 13 at set time intervals.

[0081] When the routine starts, in step S101, the integrated_ECU 13 checks whether the sunroof is open or not. That is, the integrated_ECU 13 checks whether the roof opening 10 is opened by the movement of the movable roof panel 11 to the retracting side.

[0082] Then, in step S101, if it is determined that the sunroof is not open (step S101: NO), the integrated_ECU 13 exits the routine.

[0083] On the other hand, if it is determined in step S101 that the sunroof is open (step S101: YES), the integrated_ECU 13 proceeds to step S102.

[0084] In step S102, the integrated_ECU 13 checks whether or not the control amounts for the left and right panel members 25l and 25r and the control amounts for the left and right shutters 30l and 30r have been set after the sunroof is opened.

[0085] Then, in step S102, if it is determined that the controlled variable has not yet been set (step S102: NO), the integrated_ECU 13 proceeds to step S104.

[0086] On the other hand, if it is determined in step S102 that the control amount has already been set (step S102: YES), the integrated_ECU 13 proceeds to step S103.

[0087] In step S103, the integrated_ECU 13 checks whether or not there has been a change in the deflector control conditions (see, for example, FIG. 12).

[0088] Then, in step S103, if it is determined that there has been no change in the deflector control condition (step S103: NO), the integrated_ECU 13 exits the routine as is.

[0089] On the other hand, if it is determined in step S103 that there has been a change in the deflector control condition (step S103: YES), the integrated_ECU 13 proceeds to step S104.

[0090] When proceeding from step S102 or step S103 to step S104, the integrated_ECU 13 sets the control amount for the left and right panel members 25l, 25r and the control amount for the left and right shutters 30l, 30r based on the current deflector control conditions, by referring to a pre-set map or the like.

[0091] In the following step S105, the integrated_ECU 13 executes wind deflector control based on the control values ​​set in step S104, and then exits the routine. That is, the integrated_ECU 13 controls the left and right panel members 25l, 25r and the left and right shutters 30l, 30r to states according to the respective control values, and then exits the routine.

[0092] According to this embodiment, the integrated_ECU 13 controls the raising and lowering of the deflector panel 25 and the opening and closing of the left and right ventilation openings 29l, 29r by the left and right shutters 30l, 30r in accordance with the wind speed and wind direction. In this case, when the wind pressure sensor 41 detects wind containing a crosswind component, the integrated_ECU 13 changes the opening states of the left and right ventilation openings 29l, 29r by the left and right shutters 30l, 30r.

[0093] Specifically, for example, when the wind speed is equal to or lower than a set speed and wind containing a crosswind component is detected, the integrated_ECU13 opens the ventilation openings located in the same direction as the wind direction and closes the ventilation openings located in the opposite direction to the wind direction.

[0094] This makes it possible to more effectively suppress both wind throb and wind noise.

[0095] In addition, in a configuration in which the deflector panel 25 is divided into left and right panel members 25l, 25r, when a wind including a crosswind component is detected, the integrated_ECU 13 causes the undulating states of the left and right panel members 25l, 25r to differ.

[0096] Specifically, when the integrated_ECU 13 detects wind including a crosswind component, it raises the panel members positioned in the same direction as the wind direction and lays down the panel members positioned in the opposite direction to the wind direction.

[0097] This makes it possible to more effectively suppress both wind throb and wind noise.

[0098] In the above-described embodiment, the integrated_ECU 13, the image recognition_ECU 53, the driving_ECU 54, etc. are configured with a well-known microcomputer equipped with a CPU, RAM, ROM, a non-volatile storage unit, etc., and its peripheral devices, and the ROM stores programs to be executed by the CPU and fixed data such as data tables in advance. Note that all or part of the functions of the processor may be configured with logic circuits or analog circuits, and the processing of various programs may be realized by electronic circuits such as FPGAs.

[0099] The invention described in the above embodiments is not limited to those embodiments, and various modifications can be made in the implementation stage without departing from the gist of the invention. Furthermore, each of the above embodiments includes inventions at various stages, and various inventions can be extracted by appropriate combinations of the disclosed multiple constituent elements.

[0100] For example, if some constituent elements are deleted from all the constituent elements shown in each form, and the stated problem can still be solved and the stated effect can still be obtained, then the configuration from which these constituent elements have been deleted can be extracted as an invention.
