Description

Technical Field

[0001] This invention relates to a controlled flap system for vehicles. It is particularly applicable to motor vehicles, but not limited to them. The invention also relates to a method for controlling flaps implemented by said controlled flap system. Background Technology

[0002] In the field of motor vehicles, a controlled flap system for a vehicle, known to those skilled in the art, is arranged behind the grille of a motor vehicle and includes two sets of flaps that can be in an open position and a closed position, which open or close simultaneously to allow air to pass through or prevent air from passing under the hood of the motor vehicle.

[0003] One drawback of the existing technology is that one set of lobes cannot open or close independently of the other set of lobes. Summary of the Invention

[0004] In this context, the present invention aims to provide a controlled flap system for vehicles that makes it possible to overcome the aforementioned drawbacks.

[0005] To this end, the present invention proposes a controlled flap system for a vehicle, the controlled flap system comprising two groups of flaps, each group of flaps capable of presenting an open position and a closed position, characterized in that the controlled flap system further comprises an actuator configured to drive one group of flaps in the flap group to the open position before the other group of flaps in the flap group.

[0006] According to a non-limiting embodiment, the controlled flap system for a vehicle may also include one or more additional features, which may be employed individually or in any technically possible combination thereof as described below.

[0007] According to a non-limiting embodiment, the controlled flap system further includes:

[0008] - A spring connecting the two sets of petals.

[0009] - An upper rod with a main idler cam, which is configured to be driven by a connecting rod.

[0010] - A lower rod with a secondary idler cam, the secondary idler cam being configured to be driven by the actuator, and

[0011] - The connecting rod that is connected to the actuator and connects the upper rod and the lower rod.

[0012] According to a non-limiting embodiment, the spring is configured as follows:

[0013] - When both sets of the lobes are in the closed position, they are tensioned.

[0014] - Relax to position one group of the leaflets in the open position.

[0015] - When the two groups of lobes are in the open position, they are tensioned.

[0016] According to a non-limiting embodiment, the two groups of lobes are initially in the closed position.

[0017] According to a non-limiting embodiment, one set of the lobes extends in a different plane than the other set of lobes, or the two sets of lobes are coplanar.

[0018] According to a non-limiting embodiment, the controlled flap system further includes:

[0019] - A main connecting component, which connects to one group of petals in the petal group, and includes at least one main drive finger that abuts against a main idler cam when one group of petals is in the open or closed position.

[0020] - A secondary connecting component, which connects to the petals of another group of petal groups, and includes at least one secondary drive finger that abuts against a secondary idler cam when the other group of petal groups is in an open or closed position, and slides along the secondary idler cam when one of the groups is in an open position.

[0021] A method for controlling vehicle lobes, the lobes forming part of two groups of lobes, each group of lobes capable of presenting an open position and a closed position, is also proposed, characterized in that the control method includes the step of driving one group of lobes into the open position before the other group of lobes.

[0022] According to a non-limiting embodiment, the two groups of lobes are initially in the closed position.

[0023] According to a non-limiting embodiment, in order to drive two groups of leaflets into an open position, the control method performs the step of driving one group of leaflets into an open position before the other group of leaflets.

[0024] According to a non-limiting embodiment, in order to drive two groups of lobes to a closed position, the control method performs the step of driving the other group of lobes into the closed position before one group of lobes is driven into the closed position. Attached Figure Description

[0040] Unless otherwise specified, elements that are identical in structure or function and appear in different figures shall retain the same reference numerals. Detailed Implementation

[0041] This invention relates to a controlled flap system 1 for a vehicle. (Reference) Figures 1 to 7 The invention also relates to a method 2 for controlling a vehicle's flap 100, the method being implemented by the controlled flap system 1. (See references.) Figure 8 and Figure 9 It is described herein. In one non-limiting embodiment, the vehicle is a motor vehicle. The term motor vehicle is understood to refer to any type of motor vehicle. Throughout the remainder of this specification, this embodiment is considered a non-limiting example. Therefore, throughout the remainder of this specification, the vehicle is also referred to as a motor vehicle.

[0042] The controlled flap system 1, also known as an air grille visor, is disposed behind the grille of a motor vehicle. It is connected to one or more air exchangers. The controlled flap system 1 allows air from outside the motor vehicle to pass under the hood, or prevents air from passing under the hood of the motor vehicle.

[0043] like Figure 1 As shown, in a non-limiting embodiment, the controlled flap system 1 includes:

[0044] - Two groups of lobes 100, 10a and 10b,

[0045] -Actuator 11,

[0046] -Spring 12,

[0047] - The upper rod 13a, also known as the upper rod 13a or main rod 13a, has a primary lost motion cam 131a.

[0048] - The lower lever 13b, also known as the lower lever 13b or secondary lever 13b, has a secondary lost motion cam 131b.

[0049] - Link 14.

[0050] It should be noted that, for clarity, in Figure 1 The schematic diagram shows only a few lobes 100. In the remainder of the specification, groups 10a and 10b of the lobes 100 will also be referred to as groups 10a and 10b. The two groups 10a and 10b of the lobes 100 can be in an open position p1 or a closed position p2. They are separated by a damping transverse member 15, as shown... Figure 7 As shown. Therefore, there is a group 10a of lobes 100, also called the first group 10a or upper route 10a; and a group 10b of lobes, also called the second group 10b or lower route 10b. Each group 10a, 10b includes one or more lobes 100 and the same or different number of lobes 100. Figure 7 In the non-restrictive examples, groups 10a and 10b have different numbers of lobes 100.

[0051] The lobes 100 of group 10a are interconnected via the main connecting member 101a (e.g., Figure 2b , 3b (As shown in 4b, 6a, and 6b). The lobes 100 of group 10b are interconnected via sub-connecting parts 101b (e.g., ...). Figure 2b , 3b (As shown in 4b, 6a and 6b).

[0052] In a non-limiting embodiment, each group 10a, 10b of the flaps 100 includes two groups of flaps 100, one on the right and one on the left. In this case, Figure 6a In one non-limiting embodiment shown, the main connecting member 101a includes two sides 1010a that allow each set of petals 100 to be secured individually. Similarly, in Figure 6b In one non-limiting embodiment shown, the sub-connecting member 101b includes two sides 1010b that allow each set of lobes 100 to be fastened separately.

[0053] like Figure 7As shown, the two groups 10a and 10b are initially in the closed position p2. This initially refers to the state when the vehicle is started. In one non-limiting embodiment, one group 10a extends in a different plane than the other group 10b. In another non-limiting embodiment, both groups 10a and 10b extend in the same plane. Therefore, they are coplanar. In non-limiting alternative embodiments, the two groups 10a and 10b extend in the same inclined plane, or they may extend in planes parallel to each other, or even in two different non-parallel planes.

[0054] exist Figure 6a and Figure 6b In one non-limiting embodiment shown, one of the groups 10a and 10b, group 10a, includes at least one primary drive finger 102a configured to abut against the primary idler cam 131a of the upper lever 13a when one of the groups 10a and 10b is in the open position p1 or the closed position p2. Specifically, the main connecting member 101a includes the primary drive finger 102a. In the non-limiting example shown, it includes two primary drive fingers 102a arranged on each side 1010a of the main connecting member 101a. In one non-limiting embodiment, these two primary drive fingers 102a face inward. The idler portion 132a of the primary idler cam 131a (e.g., Figure 6a (As shown) can move along the main drive finger 102a.

[0055] exist Figure 6b In one non-limiting embodiment shown, another group 10b of groups 10a and 10b includes at least one secondary drive finger 102b configured to abut against the secondary idler cam 131b of the secondary lever 13b when the other group 10b is in the open position p1 or the closed position p2. Specifically, the secondary connecting member 101b includes this secondary drive finger 102b. In the non-limiting example shown, it includes two secondary drive fingers 102b arranged on each side 1010b of the main connecting member 101b. In one non-limiting embodiment, these two secondary drive fingers 102b face inwards.

[0056] Furthermore, when one of groups 10a and 10b, group 10a, is in the open position p1, the secondary drive finger 102b slides within the secondary idler cam 131b. The idler portion 132b of the secondary idler cam 131b (e.g., Figure 6b (As shown) moves along the secondary drive finger 102b.

[0057] Actuator 11 is configured to drive one group 10a of the groups 10a and 10b of the flaps 100 into the open position p1 before the other group 10b of the groups 10a and 10b of the flaps 100. Therefore, there is a sequential opening of the flaps 100. Thus, it opens the flaps of one group of groups 10a and 10b before the other group 10b of the groups 10a and 10b. Therefore, actuator 11 can drive both groups 10a and 10b of the flaps 100 independently of each other. Therefore, a modular flap control strategy (open / close) can be achieved through a single actuator 11. In a non-limiting embodiment, each group 10a, 10b includes two sets of lobes (right and left), and the main connecting member 101a includes two sides 1010a, and the secondary connecting member 101b includes two sides 1010b. In one non-limiting embodiment, the actuator 11 is a dual-outlet actuator to balance the forces on the main connecting member 101a and the secondary connecting member 101b. The simultaneous action of forces on each side 1010a of the main connecting member 101a provides it with linear motion. The same applies to the secondary connecting member 101b. This allows unwanted forces arising from the offset of the main connecting member 101a to be limited as much as possible by the action of a single upper lever 13a. This allows unwanted forces arising from the offset of the secondary connecting member 101b to be limited as much as possible by the action of a single lower lever 13b. Having a dual-outlet actuator 11 is advantageous, especially in this kinematic type, wherein:

[0058] The guidance of the main drive fingers 102a in the main actuation section 131a of the upper lever 13a depends on the correct alignment of the assembly, that is, the two main drive fingers 102a are aligned with each other when they engage with the main actuation section 131a.

[0059] The guidance of the secondary drive finger 102b in the secondary idler section 131b of the lower lever 13b depends on the correct alignment of the assembly, that is, the two secondary drive fingers 102b are aligned with each other when they engage with the secondary idler section 131b.

[0060] Since such dual-outlet actuators are known to those skilled in the art, they will not be described in detail here.

[0061] Lobe control strategies may include:

[0062] -Open all lobes 100 in both groups 10a and 10b.

[0063] -Close all lobes 100 in both groups 10a and 10b.

[0064] - Open the flap of group 10a in one of groups 10a and 10b, and close the flap 100 of the other group 10b in the other of groups 10a and 10b.

[0065] - Close the flap of group 10a in one of groups 10a and 10b, and open the flap of group 10b in the other of groups 10a and 10b.

[0066] In one non-limiting exemplary embodiment, the flaps 100 of the two groups 10a and 10b of the flaps 100 open during the heating phase of the internal combustion engine. This occurs when the motor vehicle is slowly moving up a slope. At this time, very little air actually reaches below the engine hood, and air enters the engine hood to cool the engine.

[0067] In a non-limiting exemplary embodiment, the two groups 10a, 10b of the lobes 100 are closed when:

[0068] - When there is a desire to improve air permeability in a motor vehicle. This is done by preventing air from entering under the hood, thus avoiding turbulence under the hood. This results in increased speed, reduced fuel consumption, and consequently, reduced carbon dioxide emissions.

[0069] - In very cold periods, this keeps the air already under the hood in a closed loop, heating the engine for quick starting and thus reducing fuel consumption.

[0070] - When a motor vehicle has been stationary for several hours, this is to prevent the engine from cooling down, thus facilitating the subsequent starting of the motor vehicle.

[0071] Actuator 11 is connected to lower rod 13b. It is configured to drive lower rod 13b. Actuator 11 is driven by a motor (not shown). An electronic control unit (not shown) enables the sending of control signals to actuator 11 to cause its movement according to a defined flap control strategy.

[0072] like Figure 1 As shown, in a non-limiting embodiment, the rotation axis Ax1 of actuator 11 is the same as the rotation axis Ax2 of lower rod 13b. Furthermore, as... Figure 5a As shown, the rotation axis Ax2 of the lower rod 13b lies in the same plane as the rotation axis Ax3 of each lobe 100 of group 10b. This allows for good kinematics. For clarity, Figure 5b Only one lobe 100 is shown.

[0073] like Figure 5b As shown, the rotation axis Ax2 of the lower rod 13b is separated from the support point 113 of the actuator 11 on the lower rod 13b by a distance d1. Figure 5bAs shown, the rotation axis Ax3 of each lobe 100 in group 10b has the same distance d1 as the fastening point 1000 of each lobe 100 on the sub-connecting member 101b. In a non-limiting embodiment, the distance d1 is greater than or equal to 17 mm. It should be noted that below this value, feasibility issues may arise. Therefore, the sub-idle cam 131b of the lower rod 13b performs the same movement in distance as the sub-connecting member 101b.

[0074] Spring 12 connects two groups 10a and 10b of the connecting leaf 100. Therefore, it is fastened to one group 10a and the other group 10b via a main connecting member 101a of the connecting leaf 100 of one group 10a and the other group 10b, respectively. Figure 5a (As shown) is fastened to the main connecting part 101a, and its other end 120b (as shown) Figure 5b (As shown) It is fastened to the sub-connecting component 101b.

[0075] like Figure 2a and 2b As shown, when the two groups 10a and 10b of the flap 100 are in the closed position p2, the spring 12 is configured to be tensioned from above. Figure 7 This shows that the lobes 100 of the upper route 10a are closed and the lobes 100 of the lower route 10b are closed (stage a).

[0076] like Figure 3a and Figure 3b As shown, the spring 12 is configured to be relaxed (relaxed position) so as to position one group 10a of the group of flaps 100 in the open position p1, while the other group 10b of the group of flaps 100 remains in the closed position p2. Figure 7 This shows that the lobes 100 of the upper route 10a are open and the lobes 100 of the lower route 10b are closed (stage b).

[0077] like Figure 4a and Figure 4b As shown, when the two groups 10a and 10b of the flap 100 are in the open position p1, the spring 12 is configured to be tensioned from below. Figure 7 This shows that the lobes 100 of the upper route 10a are open and the lobes 100 of the lower route 10b are open (stage c).

[0078] like Figures 2a to 4bAs shown, the upper rod 13a and the lower rod 13b are connected by a connecting rod 14. Therefore, the upper rod 13a is configured to be driven by the connecting rod 14. The lower rod 13b is configured to be driven by the actuator 11, and because it is connected to the actuator 11, it is configured to push the connecting rod 14.

[0079] like Figure 5a As shown, in a non-limiting embodiment, the rotation axis Ax4 of the upper rod 13a lies in the same plane as the rotation axis Ax5 of each lobe 100 of the group 10a. This allows for good kinematics. For clarity, Figure 5b Only one lobe 100 is shown. The rotation axis Ax2 of the lower rod 13b and the rotation axis Ax4 of the upper rod 13a are located in the same plane.

[0080] like Figure 5a As shown, the distance d1 between the rotation axis Ax4 of the upper rod 13a and the support point 143 of the connecting rod 14 on the upper rod 13a is d1. Figure 5a As shown, the rotation axis Ax5 of each lobe 100 in group 10a has the same distance d1 as the fastening point 1001 of each lobe 100 on the main connecting member 101a. In a non-limiting embodiment, the distance d1 is less than 30 mm. Therefore, the main idler cam 131a of the upper rod 13a performs the same displacement in distance as the main connecting member 101a.

[0081] The main idler cam 131a of the upper rod 13a is configured to cooperate with at least one main drive finger 102a of the main connecting member 101a. Figure 6a In the non-limiting example shown, it engages with two main drive fingers 102a. In this case, it is a double idler cam. The secondary idler cam 131b of the lower rod 13b is configured to engage with at least one secondary drive finger 102b of the secondary connecting member 101b. Figure 6a In the non-limiting example shown, it cooperates with two secondary drive fingers 102b. In this case, it is a double idler cam.

[0082] In a non-limiting embodiment, the main idler cam 131a can be positioned within the range of -90° to +90°. The -90° position (e.g.) Figure 2b As shown, all lobes 100 corresponding to group 10a are closed (e.g.) Figure 2a As shown). 0° position (e.g.) Figure 3b As shown) all lobes 100 corresponding to group 10a are opened (e.g. Figure 3a As shown). +90° position (e.g.) Figure 4b As shown, all lobes 100 corresponding to group 10a are opened (e.g.) Figure 4a (As shown).

[0083] In a non-limiting embodiment, the auxiliary idler cam 131b can be positioned within the range of -90° to +90°. The -90° position (e.g.) Figure 2b As shown, all lobes 100 corresponding to group 10b are closed (e.g.) Figure 2a As shown). 0° position (e.g.) Figure 3b As shown, all lobes 100 corresponding to group 10b are closed (e.g.) Figure 3a As shown). +90° position (e.g.) Figure 4b As shown) all lobes 100 corresponding to group 10b are opened (e.g. Figure 4a (As shown).

[0084] Therefore, as Figure 2a and Figure 2b As shown, when the upper route 10a and the lower route 10b are in the closed position p2, the main idling cam 131a is in the -90° position and the auxiliary idling cam 131b is also in the -90° position.

[0085] Therefore, as Figure 3a and Figure 3b As shown, when the upper route 10a is in the open position p1 and the lower route 10b is in the closed position p2, the main idler cam 131a is in the 0° position and the auxiliary idler cam 131b is also in the 0° position.

[0086] Therefore, as Figure 4a and Figure 4b As shown, when the upper route 10a and the lower route 10b are in the open position p1, the main idling cam 131a is in the +90° position, and the auxiliary idling cam 131b is also in the +90° position.

[0087] Therefore, in order to move from the closed position p2 where all lobes 100 are closed to the open position p1 where all lobes 100 are open, the main idling cam 131a and the auxiliary idling cam 131b will perform a rotation of +180°.

[0088] Positions other than -90°, 0°, and +90° can be used. Therefore, in another non-limiting example, the main paving cam 131a is at a -45° position, and the auxiliary paving cam 131b is also at a -45° position. In this case, the flap 100 of the upper route 10a is half-open, while the flap 100 of the lower route 10b remains closed. Therefore, in another non-limiting example, the main paving cam 131a is at a +45° position, and the auxiliary paving cam 131b is also at a +45° position. In this case, the flap 100 of the lower route 10b is half-open, while the flap 100 of the upper route 10a is fully open. It should be noted that the flaps 100 of the upper route 10a and the lower route 10b cannot be half-open simultaneously.

[0089] It should be noted that when the main idling cam 131a and the auxiliary idling cam 131b are within the angle range of -90° to 0°, the upper path 10a is affected, while the lower path 10b remains in the closed position p2. Conversely, when the main idling cam 131a and the auxiliary idling cam 131b are between the angle range of 0° and +90°, the lower path 10b is affected, while the upper path 10a remains in the open position p1. Therefore, the groups 10a and 10b of the flaps 100 are operated independently of each other.

[0090] Therefore, depending on the control strategy of the flap 100, the flaps 100 of group 10a and / or group 10b can be opened more or less to allow more or less air to pass under the engine hood.

[0091] The connecting rod 14, which connects the upper rod 13a and the lower rod 13b, is configured to drive the upper rod 13a, that is, it is configured to rotate the upper rod 13a.

[0092] like Figure 2a As shown, when the upper route 10a and the lower route 10b are in the closed position p2, the link 14 is close to the spring 12 and is in the so-called bottom position p3.

[0093] like Figure 3a As shown, when the upper route 10a is in the open position p1 and the lower route 10b is in the closed position p2, the link 14 is further away from the spring 12 and is in the so-called intermediate position p4.

[0094] like Figure 4a As shown, when the upper route 10a and the lower route 10b are in the open position p1, the link 14 approaches the spring 12 again and is in the so-called top position p5.

[0095] The controlled flap system 1 for a vehicle, as described herein, is configured to implement a method 2 (or control method 2) for controlling flaps 100, which form part of two groups 10a, 10b of flaps 100. Referring below... Figure 8 and Figure 9 Describe control method 2. This control is performed by actuator 11.

[0096] Figure 7 The order shown is considered a non-limiting example. For example... Figure 7As shown, the lobes 100 of the upper route 10a and the lower route 10b are initially closed at p2 (stage (a)). The upper route 10a and the lower route 10b are in the closed position at p2. The lobes 100 of the upper route 10a will be opened before the lobes of the lower route 10b (stage (b)). Then, the lobes 100 of the lower route 10b will be opened (stage (c)). Finally, all the lobes 100 of the upper route 10a and the lower route 10b will be opened. The upper route 10a and the lower route 10b will then be in the open position at p1.

[0097] According to a non-limiting embodiment, control method 2 includes the following steps.

[0098] like Figure 8 As shown, control method 2 includes an initial step (E0), illustrated as F0(10a, p2, 10b, p2), where the two groups 10a and 10b of the flaps 100 are initially in the closed position p2. When the upper route 10a and the lower route 10b are initially in the closed position p2, the spring 12 is stretched upward by the main connecting member 101a. Therefore, it is tensioned from above. In addition, the main idler cam 131a of the upper rod 13a and the auxiliary idler cam 131b of the lower rod 13b are located at -90°. The main drive finger 102a of the upper route 10a abuts in the main idler cam 131a. The auxiliary drive finger 102b of the lower route 10b abuts in the auxiliary idler cam 131b.

[0099] like Figure 8 As shown, in step E1 illustrated by F1(10a, p1, 10b, p2), one of the groups 10a and 10b of the lobes 100, group 10a, is in the open position p1 before the other group 10b of the groups of the lobes 100. In the non-limiting example shown, the upper route 10a is in the open position p1.

[0100] The actuator 11 connected to the lower lever 13b causes the secondary idler cam 131b of the lower lever 13b to rotate counterclockwise. Therefore, it rotates from position -90° to 0°. The secondary idler cam 131b slides along the secondary drive finger 102b of the secondary connecting member 101b. The secondary connecting member 101b does not move. The lower path 10b connected to the flap 100 via the secondary connecting member 101b does not change position. The flap 100 of the lower path 10b remains closed.

[0101] When movement begins, the lower rod 13b, also connected to the connecting rod 14, drives the connecting rod 14; it pushes it upward. The latter performs a circular stroke and rises. The connecting rod 14, also connected to the upper rod 13a, drives the upper rod 13a and causes the latter's main idler cam 131a to rotate counterclockwise. Thus, it rotates from position -90° to 0°. The main idler cam 131a releases the main drive finger 102a from the main connecting member 101a. The spring 12 connected to the main connecting member 101a relaxes, and the main connecting member 101a descends. The flap 100 of the upper route 10a opens.

[0102] Therefore, the lobes 100 of the upper route 10a are open, while the lobes 100 of the lower route 10b remain closed. This is a configuration in which a portion of the lobes 100 of the controlled lobes system 1 is open and another portion of the lobes 100 is closed.

[0103] like Figure 8 As shown, in step E2) illustrated by F2(10a, p1, 10b, p1), another group 10b of the groups 10a and 10b of the lobes 100 is in the open position p1. In the non-limiting example shown, the lower route 10b is also in the open position p1 at this time.

[0104] The actuator 11 connected to the lower lever 13b again rotates the secondary idler cam 131b of the lower lever 13b counterclockwise. The secondary idler cam 131b thus rotates from the 0° position to +90°. Therefore, it performs a -90° rotation again. Due to the rotation of the secondary idler cam 131b, the secondary drive finger 102b of the lower path 10b of the secondary idler cam 131b, which abuts against the lower lever 13b, drives the secondary connecting member 101b downward. The spring 12 connected to the secondary connecting member 101b is stretched downward by the secondary connecting member 101b. Therefore, it is tensioned from below. The flap 100 of the lower path 10b opens.

[0105] When movement begins, the lower rod 13b, also connected to the connecting rod 14, drives the connecting rod 14; it continues to push it upward. The latter continues its circumferential stroke and continues to rise. The connecting rod 14, also connected to the upper rod 13a, drives the upper rod 13a and causes the latter's main idler cam 131a to rotate counterclockwise. Thus, the main idler cam 131a rotates from a -0° position to +90°. Thus, it performs a -90° rotation again. The main idler cam 131a slides along the main drive finger 102a of the main connecting member 101a. The main connecting member 101a does not move. The upper route 10a, whose flaps 100 are connected by the main connecting member 101a, does not change position. The flaps 100 of the upper route 10a remain open.

[0106] Therefore, the lobes 100 of the lower route 10b are open, and the lobes 100 of the upper route 10a remain open. This is the configuration in which all lobes 100 of the controlled lobe system 1 are open.

[0107] It will be noted that in order to transition from the initial step to step E2, the main idling cam 102a and the auxiliary idling cam 102b have performed a -180° rotation (in the counterclockwise direction).

[0108] It will be noted that, in order to drive the two groups 10a and 10b of the flap 100 to the open position p1, the control method 2 performs the step of driving one group 10a of the groups 10a and 10b of the flap 100 into the open position p1 before the other group 10b of the groups 10a and 10b of the flap 100. Therefore, in order to... Figure 7 In stage a, transition to Figure 7 Stage c in the process must go through Figure 7 Stage b in the process.

[0109] In addition, Figure 9 In one non-limiting embodiment shown, in order to drive the two groups 10a, 10b of the flap 100 back to the closed position p2, the control method 2 performs the step of driving the other group 10b of the groups 10a, 10b of the flap 100 to the closed position p2 before one group 10a of the groups 10a, 10b of the flap 100. Therefore, in order to... Figure 7 Phase c in Figure 7 Stage a in the process must go through Figure 7 Stage b in the process. In this case, as... Figure 9 As shown, control method 2 also includes:

[0110] - Step E3), illustrated as F3(10a, p1, 10b, p2), drives another group 10b of groups 10a and 10b to the closed position p2. In the non-limiting example shown, group 10a is in the closed position p2, and

[0111] - Step E4), illustrated as F4(10a, p2, 10b, p2), drives one of groups 10a and 10b, group 10a, to the closed position p2. In the non-limiting example shown, group 10b is subsequently in the closed position p2.

[0112] Of course, the description of the present invention is not limited to the embodiments and fields described above. Therefore, in another non-limiting embodiment, the rotation axis Ax1 of the actuator 11 lies in a plane different from the rotation axis Ax2 of the lower rod 13b and the rotation axis Ax3 of each lobe of the group 10b. Therefore, in another non-limiting embodiment, the rotation axis Ax4 of the upper rod 13a lies in a plane different from the rotation axis Ax5 of each lobe of the group 10a.

[0113] Therefore, the described invention has the following particular advantages:

[0114] -It enables flexible flap control strategies.

[0115] -This allows two groups 10a and 10b of the flaps 100 to be controlled with a single actuator 11.

[0116] - It allows for the opening or closing of all or part of the 100 lobes.
