[0002] With the development of automobiles, users have higher and higher requirements for automobile range and handling performance. As an aerodynamic device that can effectively affect the range and handling performance of automobiles, automobile tail wings have been widely used in new energy vehicles in recent years. They can independently adjust the downforce on the inner and outer wheels of the automobile and improve the stability of the automobile in high-speed cornering.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0065] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0067] Reference below Figure 1-Figure 5 The rear wing assembly 100 according to an embodiment of the present invention is described. The rear wing assembly 100 can adjust the spoiler effect through multiple spoiler strips 2, and can adapt to various different operating conditions of the vehicle. Compared with setting a complex adjustment structure for the side wing panel 4, the structure of the rear wing assembly 100 is simpler, the adjustment is more convenient, and it is not easy to cause damage to the adjustment device.

[0068] like Figure 1-Figure 5 As shown, a tail wing assembly 100 according to an embodiment of the present invention is used for a vehicle and includes: a main wing panel 1 and a spoiler strip 2 .

[0069] Wherein, the spoiler strip 2 is arranged on the side of the main wing panel 1 facing the vehicle body, and the spoiler strip 2 is movable relative to the main wing panel 1 so that the spoiler strip 2 can be opened or closed. It should be noted that the spoiler strip 2 can be movably arranged on the main wing panel 1, and the main wing panel 1 is fixedly installed on the upper rear side of the vehicle, and the spoiler strip 2 is opened or closed relative to the main wing panel 1, that is, the spoiler strip 2 can extend to at least partially protrude outside the main wing panel 1, so that the spoiler strip 2 can be opened to actively spoil the airflow located on the upper rear side of the vehicle, or the spoiler strip 2 can be stored in the main wing panel 1, so that the spoiler strip 2 is closed to reduce the spoiler effect on the airflow on the upper rear side of the vehicle, thereby helping to meet different spoiler requirements. Wherein, the spoiler strip 2 can be set to one, two, three, four or even more, that is, the number of spoiler strips 2 can be flexibly set according to actual needs.

[0070] The spoiler strip 2 can be opened to the side of the main wing panel 1 facing the vehicle body, so that during the driving process of the vehicle, a small-scale vortex structure is formed on the side of the main wing panel 1 facing the vehicle body through the spoiler effect of the spoiler strip 2, thereby reducing the air flow velocity on the lower surface of the main wing panel 1, thereby reducing the negative pressure on the lower surface of the main wing panel 1, and then reducing the pressure difference between the upper and lower surfaces of the main wing panel 1. While reducing the downforce, the pressure difference between the upper and lower surfaces of the main wing panel 1 is also reduced in the incoming flow direction, thereby reducing the contribution of the rear wing assembly 100 to the wind resistance of the vehicle, achieving low wind resistance driving of the vehicle, and shortening the acceleration time.

[0071] During the driving process of the vehicle, the state of the spoiler strip 2 can be adjusted. For example, when accelerating in a straight line, the spoiler strip 2 can be opened to drive with low wind resistance, or when decelerating in a straight line, the spoiler strip 2 can be closed to drive with high wind resistance. Thus, the vehicle can maintain a good wind resistance state under different operating conditions, thereby improving the vehicle's handling performance and cruising range. Among them, the spoiler strip 2 has a simple structure and is easy to adjust. It does not need to set a complex adjustment structure for the side wing plate 4 as in the traditional design, is not easy to be damaged, and has better structural safety and stability.

[0072] According to the rear wing assembly 100 of the embodiment of the present invention, by providing a movable spoiler strip 2, the spoiler strip 2 can be adjusted separately during the driving of the vehicle to meet the spoiler requirements under different operating conditions, such as linear acceleration, linear deceleration and other operating conditions. In addition, the spoiler strip 2 has a simple structure and is easy to adjust. It is not easy to have the problem of damage to the adjustment structure, and the cost of use is low.

[0073] In some embodiments, at least two spoiler strips 2 are provided, and at least two spoiler strips 2 are spaced apart and distributed along a first direction, and the first direction may be the left-right direction of the vehicle, that is, the first direction is the length direction of the main wing panel 1, so that the spoiler strips 2 can perform spoiler at different positions on the main wing panel 1. In addition, when specifically provided, the main wing panel 1 may be constructed as a long strip plate, so that at least two spoiler strips 2 can perform spoiler in different areas in the length direction of the main wing panel 1, in other words, at least two spoiler strips 2 can perform spoiler at different positions in the left-right direction of the vehicle, specifically, a part of at least two spoiler strips 2 is located in the left area above the vehicle, and a part is located in the right area above the vehicle, so that each area can select a corresponding spoiler state through the spoiler strips 2.

[0074] During the driving process of the vehicle, the state of at least two spoiler strips 2 can be adjusted. For example, when accelerating in a straight line, multiple spoiler strips 2 can be opened to drive with low wind resistance, or when decelerating in a straight line, multiple spoiler strips 2 can be closed to drive with high wind resistance, or when driving through a curve, the opening of at least two spoiler strips 2 can be adjusted linearly to meet the wind resistance requirements of the inner and outer sides of the curve during the curve, ensuring the stability of the vehicle, thereby enabling the vehicle to maintain a good wind resistance state under different operating conditions, improving the vehicle's handling performance and cruising range. Among them, the spoiler strip 2 has a simple structure and is easy to adjust. It does not need to set a complex adjustment structure for the side wing plate 4 as in the traditional design, is not easy to be damaged, and has better structural safety and stability.

[0075] In actual design, the number of spoiler strips 2 can be flexibly set, such as 4, 6, 8, 10 or more. Figure 1 and Figure 4 As shown, the number of spoiler strips 2 is 8, and the shapes and sizes of the 8 spoiler strips 2 can be set to be the same.

[0076] Among them, the first direction is along the transverse direction of the vehicle or the angle between the first direction and the transverse direction of the vehicle is less than 45°, such as the first direction is set to be along the transverse direction of the vehicle, or is set to be 3°, 5°, 7°, 10°, 12°, 14°, 15°, 19°, 21°, 23°, 24°, 27°, 29°, 32°, 34°, 35° with the transverse direction of the vehicle, or can be set to other angles, that is, at least two spoiler strips 2 are spaced apart along the transverse direction of the vehicle or in a direction with a smaller angle with the transverse direction of the vehicle, thereby, at least two spoiler strips 2 can selectively spoil at different positions in the transverse direction of the vehicle.

[0077] In this way, when at least two spoiler strips 2 are opened, a low wind resistance effect can be generated at various positions in the lateral direction of the vehicle, and when at least two spoiler strips 2 are closed, a high wind resistance effect can be generated at various positions in the lateral direction of the vehicle, or when the opening range of each spoiler strip 2 is different, different wind resistance effects can be generated to adapt to cornering requirements.

[0078] In some embodiments, at least two spoiler strips 2 are configured to move independently of each other, so that at least two spoiler strips 2 can be opened or closed relative to the main wing panel 1 at the same time, and at least two spoiler strips 2 can be selectively opened or closed according to actual spoiler requirements to adapt to a variety of different driving conditions.

[0079] In other words, under different working conditions, the opening and closing of at least two spoiler strips 2 do not affect each other, and each spoiler strip 2 can be opened or closed individually. Therefore, when accelerating in a straight line, decelerating in a straight line, and turning, the spoiler effect of the main wing panel 1 can be switched through the spoiler strip 2 to adapt to the spoiler requirements under different working conditions.

[0080] In some embodiments, at least two spoiler strips 2 are evenly spaced apart along the first direction. In other words, the spacing between the spoiler strips 2 can be set to be relatively uniform, so that the spoiler effect generated by the corresponding spoiler strips 2 at various positions on the side of the main wing panel 1 facing the vehicle body is relatively balanced. In this way, during the driving of the vehicle, each spoiler strip 2 can produce a relatively balanced wind resistance effect, thereby ensuring the stability and safety of the vehicle driving.

[0081] In some embodiments, the tail wing assembly 100 also includes a driving structure, which is used to drive the spoiler strip 2 to move relative to the main wing panel 1. Therefore, when the state of the spoiler strip 2 is adjusted, the spoiler strip 2 can be driven by the driving structure, that is, the driving structure can be connected to the spoiler strip 2 by power, so that when the driving structure outputs power, it can drive the spoiler strip 2 to move relative to the main wing panel 1, and then switch to an open or closed state.

[0082] Among them, the driving structure can be electrically driven, manually driven, or other driving forms such as hydraulic drive. That is, the driving form of the driving structure can be flexibly set according to actual driving requirements and setting conditions to reduce installation costs and reduce installation difficulty.

[0083] The driving structure can be fixedly installed on the main wing panel 1, such as installed inside the main wing panel 1, to achieve hidden installation of the driving structure, reduce the influence of the driving structure on the spoiler effect of the tail wing assembly 100, and ensure that the spoiler strip 2 can be accurately adjusted by the driving structure.

[0084] In a further embodiment, the driving structure includes at least two driving motors 5, and there are at least two spoiler strips 2. The at least two driving motors 5 correspond one-to-one to the at least two spoiler strips 2. The driving motors 5 are used to drive the corresponding spoiler strips 2 to move, that is, each spoiler strip 2 can be individually provided with a corresponding driving motor 5, so that the spoiler strip 2 can be electrically driven by the driving motor 5, thereby ensuring the response speed of the spoiler strip 2.

[0085] Specifically, when the driving motor 5 drives the spoiler strip 2 to open, the driving motor 5 can rotate forward to open the spoiler strip 2 relative to the main wing panel 1, or when the driving motor 5 drives the spoiler strip 2 to close, the driving motor 5 can rotate reversely to close the spoiler strip 2 relative to the main wing panel 1. The structure is simple and flexible switching of the state of the spoiler strip 2 can be achieved.

[0086] In some embodiments, at least two drive motors 5 are driven independently of each other, that is, the operation of two adjacent drive motors 5 is independent of each other, and the driving of the corresponding spoiler strips 2 is also independent of each other. In other words, when each drive motor 5 drives the corresponding spoiler strip 2 to open or close, it does not interfere with the opening or closing of other spoiler strips 2. Therefore, each spoiler strip 2 can be opened or closed to the same opening, or opened or closed at an independent opening, thereby enriching the spoiler state of each spoiler strip 2 and meeting different types of spoiler requirements.

[0087] In some embodiments, the driving structure also includes a rotating shaft 51 connected to the driving motor 5, and the rotating shaft 51 is provided with a winding rope 52 connected to the spoiler strip 2. When the rotating shaft 51 rotates, the spoiler strip 2 is driven to move through the winding rope 52. In other words, the rotating shaft 51 can be driven to rotate by the driving motor 5 to drive the winding rope 52 to be selectively wound or unfolded, thereby driving the spoiler strip 2 to open or close relative to the main wing panel 1.

[0088] Specifically, the motor shaft of the driving motor 5 is coaxially connected to the rotating shaft 51, and can also be dynamically connected to the rotating shaft 51 through a gear reduction structure, so that the rotating shaft 51 can be driven by the motor shaft to rotate. One end of the retracting rope 52 can be fixed to the rotating shaft 51, so that when the rotating shaft 51 rotates, the retracting rope 52 can be wound around the rotating shaft 51, or unfolded relative to the rotating shaft 51, and at the same time, the other end of the retracting rope 52 can be fixed to the spoiler strip 2 to drive the spoiler strip 2 to move relative to the main wing panel 1.

[0089] The reeling rope 52 may be constructed as a flexible steel bar, so that the flexible steel bar has sufficient structural strength to drive the spoiler strip 2 to move.

[0090] In actual design, at least one reel 52 is provided, that is, the reel 52 can be provided as one or more, so that the multiple reel 52 can drive the spoiler strip 2 together to ensure the reliability of the driving of the spoiler strip 2.

[0091] In some embodiments, each spoiler strip 2 corresponds to a rotating shaft 51 and a winding rope 52. One end of the spoiler strip 2 is rotatably connected to the main wing panel 1, and the other end of the spoiler strip 2 is connected to the corresponding rotating shaft 51 through the winding rope 52. In other words, the winding rope 52 can drive the other end of the spoiler strip 2 to rotate relative to one end thereof, and then open or close relative to the main wing panel 1, thereby realizing the rotating installation of the spoiler strip 2, which is beneficial to reducing installation costs and improving installation efficiency.

[0092] Specifically, Figure 2 As shown, the spoiler strip 2 is constructed in the shape of a long strip, and the spoiler strip 2 can be arranged to extend along the longitudinal direction of the vehicle, that is, the front-to-back direction. The rear end of the spoiler strip 2 can be rotatably connected to the main wing panel 1, and the front end of the spoiler strip 2 is fixedly connected to the end of the winding rope 52, and then the front end of the spoiler strip 2 is driven to rotate relative to the rear end by the winding rope 52, so that at least a part of the front end of the spoiler strip 2 extends out of the main wing panel 1 to produce a spoiler effect.

[0093] In some embodiments, each spoiler strip 2 corresponds to two rotating shafts 51 and two retracting ropes 52 , and both ends of the spoiler strip 2 are respectively connected to the retracting ropes 52 of the two rotating shafts 51 , so that the two rotating shafts 51 can simultaneously drive the spoiler strip 2 to move relative to the main wing panel 1 .

[0094] Specifically, Figure 5 As shown, the spoiler strip 2 extends in the front-to-back direction, and a retracting rope 52 is respectively connected to the front and rear ends of the spoiler strip 2, and the upper end of each retracting rope 52 is connected to a rotating shaft 51, thereby, the rotating shaft 51 can be driven to rotate by the driving motor 5, so that the front and rear ends of the spoiler strip 2 are opened or closed at the same time under the action of the two retracting ropes 52, thereby realizing the adjustment of the spoiler effect of the spoiler strip 2.

[0095] In other words, the spoiler strip 2 does not need to be rotationally connected to the main wing panel 1, and the spoiler strip 2 can be directly adjusted and driven by the retracted rope 52, thereby allowing the spoiler strip 2 to extend entirely outside the main wing panel 1, thereby increasing the spoiler volume of the spoiler strip 2 and enhancing the spoiler effect.

[0096] In some embodiments, a tail cavity is formed in the main wing panel 1, the main wing panel 1 is provided with an active opening communicating with the tail cavity, the driving structure is located in the tail cavity, and the spoiler strip 2 is movably mounted at the active opening. Thus, the driving structure can drive the spoiler cavity to extend from the active opening to the outside of the main wing panel 1, or can be retracted from the active opening into the tail cavity, thereby realizing flexible switching of the position of the spoiler strip 2.

[0097] In other words, the main wing panel 1 can be constructed as a hollow plate, thereby achieving a weight-reducing design of the main wing panel 1 , which is beneficial to reducing the overall weight of the main wing panel 1 .

[0098] At the same time, the driving structure is installed in the tail cavity, so that the main wing panel 1 can protect the driving structure, ensuring that the driving motor 5, the rotating shaft 51, and the winding rope 52 are in a relatively closed internal environment, thereby ensuring that the driving motor 5 can accurately and reliably drive the rotating shaft 51 to rotate, thereby realizing the winding of the winding rope 52 and the adjustment of the spoiler strip 2.

[0099] In addition, the movable opening connects the inside and outside of the tail wing cavity. When the spoiler strip 2 switches between the inside and outside of the tail wing cavity, the inner wall of the movable opening can guide the movement of the spoiler strip 2 so that the spoiler strip 2 can be extended or retracted according to the target trajectory, thereby ensuring the accurate adjustment of the spoiler strip 2.

[0100] In some embodiments, the main wing panel 1 has a wind guide surface 11, and the spoiler strip 2 can be movably arranged on the wind guide surface 11. In other words, the main wing panel 1 can actively guide part of the airflow encountered during the vehicle's driving process through the wind guide surface 11. At the same time, the spoiler strip 2 is arranged on the wind guide surface 11, so that the main wing panel 1 can flexibly use the spoiler strip 2 arranged on the wind guide surface 11 to adjust the spoiler effect during the process of guiding the air through the wind guide surface 11.

[0101] That is to say, during the process of airflow guidance by the wind guide surface 11, the airflow near the main wing panel 1 can be concentrated and flow along the wind guide surface 11, and then when the spoiler strip 2 is opened and extended from the wind guide surface 11, more airflow can be able to produce a spoiler effect under the action of the spoiler strip 2, thereby enhancing the spoiler effect and improving the vehicle's handling performance.

[0102] In some embodiments, the outer side surface of the spoiler strip 2 is constructed as a spoiler surface 21, and the spoiler surface 21 is flush with the wind guide surface 11 when the spoiler strip 2 is closed, that is, when the spoiler strip 2 is stored in the movable opening, the side of the spoiler strip 2 exposed outside the main wing panel 1 is flush with the wind guide surface 11.

[0103] Specifically, in actual design, the wind guide surface 11 can be constructed as an arc-shaped surface, and the spoiler surface 21 can also be constructed as an arc-shaped surface, and the curvature of the wind guide surface 11 is the same as the curvature of the spoiler surface 21, so that when the spoiler strip 2 is opened relative to the main wing panel 1, the spoiler surface 21 can play a good spoiler role, and when the spoiler strip 2 is closed relative to the main wing panel 1, the spoiler surface 21 is flush with the wind guide surface 11, that is, the spoiler surface 21 and the wind guide surface 11 jointly guide the wind, which can better achieve a smooth transition of the flow velocity on the lower surface of the main wing panel 1, and solve the problem of local flow loss caused by the imbalance of the tail wing height.

[0104] Therefore, when the spoiler strip 2 is closed, the main wing panel 1 can form an integral surface on the wind guide surface 11, that is, no convex or concave structure will be formed due to the spoiler strip 2, thereby ensuring the normal wind guiding effect of the main wing panel 1 and reducing the influence of the spoiler strip 2 on the main wing panel 1 in the non-spoiler state.

[0105] like Figure 3 As shown, the spoiler strip 2 is received in the movable opening, and the spoiler surface 21 is flush with the wind guide surface 11, and the two can play a wind guide role together.

[0106] In some embodiments, the bottom surface of the main wing panel 1 is configured as a wind guide surface 11. Figure 1 As shown, the main wing panel 1 is installed above the rear of the vehicle, and the airflow on the upper surface of the vehicle can flow to the bottom of the main wing panel 1 and be guided backward from the wind guide surface 11 to achieve the function of airflow guidance and reduce wind resistance. In other words, the spoiler strip 2 can be set on the bottom surface of the main wing panel 1, and then when the spoiler strip 2 is opened, the spoiler strip 2 can play a spoiler effect on the bottom surface of the main wing panel 1, thereby reducing wind resistance.

[0107] Specifically, Figure 1 and Figure 4 As shown, a plurality of spoiler strips 2 are arranged at intervals along the length direction of the main wing panel 1 on the bottom surface of the main wing panel 1 . The spoiler strips 2 can be opened downward or closed upward, thereby selectively generating a spoiler effect at the bottom of the main wing panel 1 .

[0108] In some embodiments, the tail wing assembly 100 also includes a mounting bracket 3, which is connected to the main wing panel 1. The mounting bracket 3 is used to be connected to the vehicle body, and the mounting bracket 3 and the spoiler strip 2 are located on the same side of the main wing panel 1 to achieve the installation and fixation of the main wing panel 1 relative to the vehicle body and the spoiler effect.

[0109] Specifically, Figure 1 As shown, the mounting bracket 3 is arranged at the bottom of the main wing panel 1, and the mounting bracket 3 can be constructed in a columnar shape, the lower end of the mounting bracket 3 is fixed to the vehicle body, and the upper end is fixedly connected to the bottom surface of the main wing panel 1. Among them, the mounting bracket 3 can be set to multiple, such as setting the mounting bracket 3 to two, three or more. Figure 1 As shown, two mounting brackets 3 are provided, and the two mounting brackets 3 are respectively connected to the areas close to the two ends of the main wing panel 1, so that the two mounting brackets 3 can play a role of stable support at the bottom of the two ends of the main wing panel 1, thereby ensuring the installation stability of the main wing panel 1.

[0110] The bottom surface of the main wing panel 1 is fixed to the top of the vehicle body through the mounting bracket 3, and the bottom surface of the main wing panel 1 is separated from the top surface of the vehicle body to form a flow space, and a plurality of spoiler strips 2 are arranged on the bottom surface of the main wing panel 1, so that the plurality of spoiler strips 2 are located on the top wall in the flow space, and then when the spoiler strips 2 are opened, the airflow in the flow space can be disturbed, thereby realizing the adjustment of wind resistance.

[0111] In some embodiments, the main wing panel 1 is extended along the lateral direction of the vehicle, and a side wing panel 4 is provided at the end of the main wing panel 1. The side wing panel 4 is spaced apart from the spoiler strip 2. The side wing panel 4 can guide the air together with the main wing panel 1.

[0112] Specifically, Figure 1 As shown, there are two side wing panels 4, and the two side wing panels 4 are connected to the two ends of the main wing panel 1, and a plurality of spoiler strips 2 are arranged between the two side wing panels 4. The structure is simple, and the airflow above the rear of the vehicle can be guided, which is beneficial to improving the driving performance of the vehicle.

[0113] The invention also provides a control method for the tail wing assembly.

[0114] According to the control method of the tail wing assembly of the embodiment of the present invention, the control method is applicable to the tail wing assembly of any of the above embodiments, there are at least two spoiler strips, and the control method includes:

[0115] S1: Acquire the driving state of the vehicle. The driving state of the vehicle can be acquired from the vehicle controller, and the driving state includes a low wind resistance state, a high wind resistance state, and a high downforce state.

[0116] S2: According to the driving state of the vehicle, at least two spoiler strips are controlled to move to the spoiler state corresponding to the driving state. In other words, after determining the type of the driving state of the vehicle, the opening state of at least two spoiler strips can be controlled so that the spoiler strips can adapt to the wind resistance requirements under different spoiler states, and then when the vehicle drives to different states, it can have the corresponding wind resistance state, improve the handling performance of the whole vehicle, and meet different types of operation requirements.

[0117] In this way, the wind resistance state of the tail wing assembly can be adjusted, and the wind resistance can be adjusted in this way without setting up a complex adjustment structure to adjust the side tail wing, which reduces the design difficulty of the adjustment mechanism, reduces the failure rate of the adjustment mechanism of the side tail wing, and improves the structural reliability of the tail wing assembly.

[0118] In some embodiments, in S2: controlling at least two spoiler strips to move to spoiler states corresponding to the driving state respectively includes:

[0119] When the vehicle is in a straight-line driving state, the opening degrees of at least two spoiler strips relative to the main wing panel are controlled to be the same. In this way, at least two spoiler strips can have a relatively balanced spoiler state, avoiding uneven spoiler effects and unstable driving, and maintaining an effective wind resistance state during the straight-line driving of the vehicle.

[0120] Furthermore, when the driving state is a turning driving state, the opening of at least two spoilers relative to the main wing is controlled to be linearly distributed, so that the wind resistance of at least two spoilers changes linearly in the length direction of the main wing. That is, when the vehicle is turning, the wind resistance of at least two spoilers can adapt to the wind resistance requirement of the vehicle when turning, thereby ensuring that the force of the vehicle is stable during the turning process, thereby achieving stable turning of the vehicle.

[0121] Specifically, Figure 6 As shown, during the driving process of the vehicle, S01 is executed: the driving state of the vehicle can be obtained in real time;

[0122] After the driving state is obtained, S02 is executed: determining whether the vehicle is driving in a straight line;

[0123] After it is determined in S02 that the vehicle is traveling in a straight line, at least two spoiler strips may be adjusted to the same opening degree, and after it is determined in S02 that the vehicle is not traveling in a straight line, S05 is executed: that is, the drive motor is controlled to open at least two spoiler strips in sequence, so that at least two spoiler strips are linearly distributed along the extension direction of the main wing panel to achieve high-speed cornering. Thus, good wind resistance performance can be achieved in both straight-line driving and cornering driving, ensuring smooth driving of the vehicle.

[0124] In some embodiments, controlling the opening degrees of at least two spoiler strips relative to the main wing panel to be the same comprises:

[0125] When the driving state is a straight-line acceleration driving state, at least two spoiler strips are controlled to open relative to the main wing panel, so that at least two spoiler strips are switched to the open state, thereby facilitating the increase of the driving speed of the vehicle, that is, achieving low wind resistance driving.

[0126] Furthermore, when the driving state is a straight-line deceleration driving state, at least two spoiler strips are controlled to be closed relative to the main wing panel, so that at least two spoiler strips are switched to a closed state, thereby helping to reduce the driving speed of the vehicle and achieve high wind resistance driving.

[0127] In other words, when the vehicle is traveling in a straight line, if the vehicle controller detects that the vehicle is accelerating, at least two spoiler strips can be switched to open synchronously to form a low wind resistance state, which is conducive to the acceleration of the vehicle. Similarly, when it is detected that the vehicle is decelerating, at least two spoiler strips can be switched to closed synchronously to form a high wind resistance state, which is conducive to the deceleration of the vehicle. In this way, at least two spoiler strips can adapt to the wind resistance requirements of the vehicle when traveling in a straight line, thereby improving the handling performance of the vehicle.

[0128] Specifically, Figure 6As shown, after it is determined in S02 that the vehicle is traveling in a straight line, S03 may be executed: further determining whether the vehicle is traveling at an accelerated speed; if it is determined in S03 that the vehicle is traveling at an accelerated speed, S04 may be executed: controlling the drive motor to open at least two spoiler strips to achieve low wind resistance traveling; if it is determined in S03 that the vehicle is traveling at a non-accelerated speed, S06 may be executed: determining whether the vehicle is traveling at a decelerated speed, and if it is traveling at a decelerated speed, S07 may be executed: controlling the drive motor to close at least two spoiler strips to achieve high wind resistance traveling.

[0129] In a further embodiment, controlling at least two spoiler strips to open relative to the main wing panel comprises:

[0130] Detect the opening range of the main wing panel;

[0131] When the opening range of the main wing panel does not meet the spoiler requirements, the spoiler strips are controlled to be fully opened and the opening degree is maximum, so that at least two spoiler strips can produce the spoiler effect to the greatest extent, reduce the wind resistance of the vehicle, increase the vehicle's driving speed, and achieve straight-line acceleration.

[0132] Specifically, Figure 7 As shown, during the vehicle's straight-line acceleration, the control method is performed as follows:

[0133] First, S041 is executed: the processor receives a straight-line acceleration driving signal;

[0134] Execute S042: monitor the opening and closing status of spoiler strips;

[0135] Execute S043: determine whether the opening of the spoiler strip meets the requirement;

[0136] If the opening of the spoiler strips does not meet the requirement, execute S044: all spoiler strips are opened, and the opening is maximum;

[0137] If the opening of the spoiler strip meets the requirement, execute S045: do not perform any adjustment operation.

[0138] And, controlling at least two spoiler strips to be closed relative to the main wing panel comprises:

[0139] Detect the closing range of the main wing panel;

[0140] When the closing range of the main wing panel does not meet the spoiler requirement, all the spoiler strips are controlled to be closed, so that at least two spoiler strips can be closed to the maximum extent, thereby maximizing the wind resistance of the vehicle, reducing the vehicle's driving speed, and achieving straight-line deceleration.

[0141] Specifically, Figure 8 As shown, during the vehicle's straight-line deceleration, the control method is performed as follows:

[0142] First, S071 is executed: the processor receives a straight-line deceleration driving signal;

[0143] Execute S072: monitor the opening and closing status of spoiler strips;

[0144] Execute S073: determine whether the opening of the spoiler strip meets the requirement;

[0145] If the opening degree of the spoiler strips does not meet the requirement, execute S074: close all spoiler strips;

[0146] If the opening degree of the spoiler strip meets the requirement, execute S075: do not perform any adjustment operation.

[0147] In some embodiments, controlling the opening of at least two spoiler strips relative to the main wing panel to be linearly distributed comprises:

[0148] Obtain the inner side and outer side of the vehicle when turning;

[0149] The opening of at least two spoilers is set to increase linearly from the inner side of the bend to the outer side of the bend, so that the wind resistance of the vehicle is larger on the inner side of the bend and smaller on the outer side of the bend, which is conducive to the vehicle turning quickly. Figure 4 As shown in FIG. 1 , there are 8 spoiler strips, and during the cornering process, the opening of the 8 spoiler strips gradually increases from the inner side of the corner to the outer side of the corner. Figure 4 The N shown in the figure is the inside of the turn, and the W is the outside of the turn.

[0150] Specifically, Fig. 9 As shown, the number of spoiler strips can be set to 8. When the vehicle is turning, the control method is performed as follows:

[0151] S051 is first executed: the processor receives a signal for entering a curve;

[0152] Execute S052: renumber the plurality of spoiler strips according to the inner and outer sides of the curve; for example, the plurality of spoiler strips are numbered 1, 2, ..., 7, 8 in sequence from the inner side to the outer side;

[0153] Execute S053: monitor the opening and closing status of the spoiler strip;

[0154] Execute S054: determine whether the opening of the spoiler strip meets the requirement;

[0155] If the opening of the spoiler strip does not meet the requirement, execute S055; close the spoiler strip numbered 1, open the spoiler strip numbered 8 to the maximum, and open the spoiler strips numbered 2 to 7 linearly;

[0156] If the opening of the spoiler strip meets the requirement, execute S056: do not perform any adjustment operation.

[0157] And, if Fig.10As shown in the figure, it is the adjustment algorithm of the opening of the rear spoiler strip when the car is driving:

[0158] ① Get the current spoiler strip opening;

[0159] ②According to the vehicle driving status, the target spoiler strip opening is obtained. The maximum spoiler strip opening is set to 1, and the spoiler strip closing is set to 0. The target spoiler strip opening calculation formula is as follows:

[0160] The car accelerates in a straight line: A_n=1,n=1,...,8;

[0161] The car decelerates while driving in a straight line: A_n=0,n=1,...,8;

[0162] Car entering a curve: A_n=1 / 7*(n-1), n=1,...,8;

[0163] ③ Determine whether the current spoiler strip opening is equal to the target spoiler strip opening. If they are equal, no operation is performed;

[0164] ④ If the current spoiler strip opening is not equal to the target spoiler strip opening, calculate the deviation between the current spoiler strip opening and the target spoiler strip opening. The specific calculation formula is as follows:

[0165] d1=A1-a1; ...;

[0167] d8 = A8-a8;

[0168] ⑤ The driving motors 1-8 receive the opening deviations d1, ..., d8;

[0169] ⑥ The drive motors 1-8 rotate according to the spoiler strip opening deviation to achieve the target spoiler strip opening. Finally, when the car enters a curve at high speed, the spoiler strip opening on the lower surface of the main wing panel is as follows: Figure 4 shown.

[0170] Therefore, through the above control method, the multiple spoiler strips on the main wing panel can be flexibly adjusted according to the driving state of the vehicle to meet the wind resistance requirements of the vehicle under different driving conditions and ensure that the vehicle has good handling performance in all driving states.
