[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.
[0050] Please refer to Figure 1, this application proposes a method for controlling a rear wing, including:
[0051] S100: Obtain the environmental information of the vehicle;
[0052] S200: Control the rear wing to open or close according to the environmental information.
[0053] In the technical solution of this application, by obtaining the environmental information of the vehicle and automatically controlling the opening or closing of the rear wing accordingly, the intelligent opening and closing of the rear wing based on the external environment is realized. This intelligent regulation mechanism not only reduces the need for manual adjustment by the driver, improves driving concentration and safety, but also ensures that the state of the rear wing matches the environmental conditions. Specifically, when the environmental conditions are suitable for the rear wing to open, the system will automatically open the rear wing. At this time, the rear wing can provide the necessary downforce, enhance the stability and controllability of the vehicle, and improve driving safety and experience. When the environmental conditions do not require or do not allow the rear wing to open, the system will automatically close the rear wing. Closing the rear wing can, on the one hand, reduce air resistance and unnecessary energy consumption, thereby improving energy efficiency and extending the cruising range; on the other hand, it can avoid potential risks and mechanical damage caused by the opening of the rear wing in unsuitable environments. In summary, this method realizes the intelligent opening and closing of the rear wing based on the external environment, reduces the need for manual adjustment by the driver, ensures that the state of the rear wing matches the environmental conditions, optimizes vehicle energy consumption and performance, and improves driving experience and vehicle efficiency.
[0054] Please refer to Figure 2 , in some embodiments, the environmental information includes the distance between the obstacle located laterally on the vehicle and the vehicle, and the step S200 of controlling the rear wing to open or close according to the environmental information includes:
[0055] S210: When the distance is greater than or equal to the preset distance, control the rear wing to close.
[0056] In these embodiments, when the distance between the obstacle located laterally on the vehicle and the vehicle is greater than or equal to the preset distance, it indicates that the driving environment is relatively safe, and even if the vehicle has a slight deviation, it will not pose a significant danger. In this case, the rear wing can be closed to reduce air resistance, thereby improving energy efficiency and reducing unnecessary energy consumption. It can be understood that if the distance between the obstacle located laterally on the vehicle and the vehicle is less than the preset distance, it means that even a slight deviation during driving will pose a danger. At this time, it is necessary to open or keep the rear wing in the open state to improve the controllability of the vehicle and avoid deviation risks.
[0057] In some embodiments, the preset spacing is set between 10m and 15m. It can be understood that if the preset spacing is too small (e.g., set to 5m), when the actual spacing between an obstacle on the lateral side of the vehicle and the vehicle is greater than or equal to the preset spacing (such as 6m), the system will determine that the driving environment is "relatively safe" and thus close the spoiler. However, in fact, a lateral distance of 6m may still be relatively small. In this case, closing the spoiler will cause the vehicle to lack sufficient downforce to cope with potential deviation risks. Especially when driving at high speeds or in complex road conditions, it may lead to danger. Therefore, too small a preset spacing may cause the system to close the spoiler when it should be opened, failing to provide the necessary stability and handling support in a timely manner. Once a slight deviation occurs, the vehicle may approach the obstacle, increasing the risk of collision. On the contrary, if the preset spacing is too large (e.g., set to 20m), when the actual spacing between an obstacle on the lateral side of the vehicle and the vehicle is less than the preset spacing (such as 18m), the system will determine that the driving environment "has a deviation risk" and thus keep the spoiler open. However, in fact, a lateral distance of 18m is already safe enough. In this case, keeping the spoiler open is unnecessary, which will increase air resistance, resulting in a decrease in energy efficiency and energy waste. Too large a preset spacing will cause the spoiler to remain open when it could have been closed, unable to effectively reduce air resistance, not only wasting energy but also possibly affecting operations such as acceleration and reducing the driving experience. In summary, too small a preset spacing will cause the system to misjudge as safe and close the spoiler, but in fact, the lateral spacing may still be relatively small, with a deviation risk, thus increasing potential safety hazards; too large a preset spacing will cause the system to misjudge as dangerous and keep the spoiler open, but in fact, the lateral spacing is already safe enough, thus wasting energy and reducing the driving experience. Therefore, setting the preset spacing between 10m and 15m can achieve the best balance between safety and performance optimization. This range can ensure that the spoiler is closed in a truly safe situation to improve energy efficiency, and can also open the spoiler in a timely manner in a potentially dangerous situation to enhance vehicle stability and ensure driving safety.
[0058] Please refer to Figure 3 , in some embodiments, the environmental information includes the environmental temperature. The step S200 of controlling the opening or closing of the spoiler according to the environmental information includes:
[0059] S220: When the environmental temperature is less than or equal to the preset temperature, control the spoiler to close.
[0060] In these embodiments, when the ambient temperature is less than or equal to a preset temperature, the control fin is closed. It can be understood that in a low-temperature environment, moisture in the air is likely to condense on the surface of the fin, and even frost or ice may form. If there is condensed water on the surface of the fin, or if frosting or icing occurs, it will not only affect its normal operation but may also cause damage to mechanical components. Closing the fin can reduce the time it is exposed to the external environment, thereby reducing the risk of condensation, frosting, or icing, extending the service life, and reducing maintenance costs. In addition, in a low-temperature environment, the air density usually increases, which means that the air resistance encountered when the vehicle is moving will also increase accordingly. Closing the fin can reduce this additional air resistance, thus helping to reduce energy consumption.
[0061] In some embodiments, the preset temperature is between 0°C and 20°C. It can be understood that if the preset temperature is too low (for example, set to -10°C), when the actual ambient temperature is already low (such as -5°C), the system will still consider the current temperature suitable and not close the fin. However, in such a low-temperature environment, moisture in the air is likely to condense on the surface of the fin and form frost or ice, resulting in the fin being unable to operate normally and even causing damage to mechanical components. In addition, low temperature will increase the air density, increasing the air resistance when the vehicle is moving, and the unclosed fin will instead increase unnecessary energy consumption. If the preset temperature is too high (for example, set to 30°C), when the actual ambient temperature is lower than the preset temperature but still relatively high (such as 25°C), the system will determine that the fin needs to be closed. However, in fact, in an environment of 25°C, the air density is low and the risks of condensed water, frosting, and icing are small. Closing the fin at this time is not only unnecessary but also affects the role of the fin in optimizing the vehicle's aerodynamic performance. This may lead to a decrease in handling performance, especially when driving at high speeds. Without the downforce provided by the fin, the vehicle's stability will be affected. In summary, too low a preset temperature will cause the system to misjudge as suitable and not close the fin, increasing the risk of icing and frosting on the fin surface, affecting its normal operation and possibly causing damage to mechanical components. Too high a preset temperature will cause the system to misjudge as needing to close the fin, even when the actual temperature is suitable, affecting the function of optimizing the vehicle's performance. Therefore, setting the preset temperature between 0°C and 20°C can avoid the harm caused by the fin being open in a low-temperature environment while ensuring that the aerodynamic advantages of the fin are fully utilized within the suitable temperature range, thereby achieving the best energy efficiency and driving safety.
[0062] Please refer to Figure 4 , in some embodiments, the environmental information includes weather information, and the step S200 of controlling the fin to open or close according to the environmental information includes:
[0063] S230: When the weather information includes rain or snow weather information, control the fin to close.
[0064] In these embodiments, rainy and snowy weather includes pure rain, snow, sleet, etc. Specifically, under harsh weather conditions such as rain, snow, or sleet, the road surface usually becomes slippery or covered with snow, resulting in a significant decrease in tire grip. Although increasing downforce can increase the contact pressure between the tire and the ground, thereby theoretically increasing grip, on a slippery road surface, excessive downforce may cause the tire to slip, especially when there is a lot of water or snow accumulation. In addition, the "water film effect" in rainy and snowy weather may also make the effect of increasing downforce counterproductive, leading to an increased risk of slipping. At the same time, in weather such as rain, snow, or sleet, the driving resistance of the vehicle itself has already increased due to the slippery road surface and increased wind resistance. If the rear wing remains open, it will further increase air resistance, resulting in unnecessary energy consumption. Closing the rear wing can, to a certain extent, reduce this additional air resistance and optimize the overall energy consumption performance of the vehicle. In addition, closing the rear wing can also reduce the possibility of rain, snow, or mixtures accumulating on the rear wing surface, avoiding the normal operation of the rear wing being affected by ice accumulation or water film, and ensuring its best performance under dry conditions. At the same time, this also reduces the time that mechanical components are exposed to a humid environment and extends the service life of the system. In summary, by closing the rear wing under harsh weather conditions such as rain, snow, or sleet, the overall performance of the vehicle can be optimized while ensuring driving safety, and unnecessary energy consumption and maintenance costs can be reduced. Whether it is pure rain, snow, or complex sleet weather, this strategy can effectively improve the adaptability and reliability of the vehicle under various harsh weather conditions.
[0065] Please refer to Figure 5 , in some embodiments, the method for controlling the rear wing further includes:
[0066] S300: Obtain the speed information of the vehicle;
[0067] S400: Control the rear wing to open or close according to the speed information.
[0068] In these embodiments, based on the vehicle speed information, the opening and closing of the rear wing are controlled. At the same time, combined with environmental information (such as obstacle spacing, environmental temperature, and weather information), the system can make more accurate decisions under different driving conditions, thereby improving the overall driving safety and performance optimization effect. This comprehensive control strategy not only gives full play to the functional advantages of the rear wing but also takes into account the adaptability and reliability under various complex driving scenarios.
[0069] Please refer to Figure 6 , in some embodiments, step S400 of controlling the rear wing to open or close according to the speed information includes:
[0070] S410: When the vehicle speed is less than or equal to the first preset vehicle speed, control the rear wing to close.
[0071] In these embodiments, by setting a first preset vehicle speed, the system can automatically close the spoiler under low-speed driving conditions. When driving at low speed, the vehicle has a relatively low demand for downforce, and the presence of the spoiler will instead increase unnecessary air resistance, resulting in increased energy consumption. Closing the spoiler can effectively reduce this additional resistance, thereby optimizing the vehicle's energy efficiency and reducing mechanical wear.
[0072] Please refer to Figure 7 , in some embodiments, when the vehicle speed is less than or equal to the first preset vehicle speed, the step S410 of controlling the spoiler to close includes:
[0073] S411: When the vehicle speed is less than or equal to the first preset vehicle speed, and the duration of the vehicle speed less than or equal to the first preset vehicle speed is greater than or equal to a preset duration, control the spoiler to close.
[0074] In these embodiments, by introducing the duration as one of the judgment conditions, the system can more intelligently avoid frequent opening and closing of the spoiler due to short-term speed fluctuations. Specifically, in actual driving, the vehicle speed may experience instantaneous fluctuations due to traffic conditions or short-term deceleration. If only the vehicle speed being less than or equal to the first preset vehicle speed is used as the sole condition for closing the spoiler, it may lead to frequent opening and closing of the spoiler, increasing energy consumption and mechanical wear. By adding the judgment condition of duration, short-term speed changes can be effectively filtered out, ensuring that the spoiler operates only when it truly needs to be closed. Frequent opening and closing of the spoiler may cause interference to the driver and reduce the driving experience. By setting a preset duration, the spoiler is only closed after the low-speed state has persisted for a certain period. This design can significantly improve the reliability of the system and the user experience. The addition of the duration can also ensure that the operation of the spoiler better meets the actual driving needs. For example, when encountering a short-term deceleration during high-speed driving (such as passing a curve or avoiding an obstacle), the system will not immediately close the spoiler, thus avoiding a decrease in aerodynamic performance due to the closing of the spoiler. Only when the vehicle is in a low-speed state for a long time (such as entering urban roads or waiting at a stop), the system will close the spoiler to reduce unnecessary air resistance and optimize energy efficiency.
[0075] In some embodiments, the preset duration is greater than or equal to 3 s. This setting can avoid the frequent opening and closing of the tail wing due to short-term speed fluctuations while ensuring that the system's judgment of the low-speed state has sufficient sensitivity and reliability. Specifically, a time threshold of 3 seconds is sufficient to filter out speed changes caused by traffic conditions, short-term deceleration, or other transient factors, thus avoiding unnecessary tail wing operations. At the same time, this duration is not too long to delay the timing of closing the tail wing, ensuring that when the vehicle truly enters a continuous low-speed state (such as in urban congested sections or waiting at a stop), the tail wing can be closed in a timely manner to reduce air resistance and optimize energy efficiency. By reasonably setting the preset duration, the system can achieve a balance between response speed and stability, further enhancing the driving experience and overall performance. The preset duration can be 3 s, 4 s, 5 s, 10 s, etc.
[0076] Please refer to Figure 8 , in some embodiments, step S400 of controlling the opening or closing of the tail wing according to the speed information includes:
[0077] S421: When the vehicle speed is greater than the first preset vehicle speed and less than or equal to the second preset vehicle speed, obtain the acceleration of the vehicle, where the second preset vehicle speed is greater than the first preset vehicle speed;
[0078] S422: When the acceleration is greater than zero, control the tail wing to close.
[0079] In these embodiments, the system is capable of dynamically adjusting the state of the rear wing according to the acceleration of the vehicle when the vehicle speed is greater than the first preset vehicle speed and less than or equal to the second preset vehicle speed. Specifically, when the vehicle speed is greater than the first preset vehicle speed, the vehicle speed is already relatively high, and additional stability may be required. There is a certain need to open the rear wing to provide downforce. However, within this speed range, if the vehicle is accelerating (i.e., the acceleration is greater than zero), it means that the driver intends to increase the vehicle speed. In this case, to reduce air resistance and improve acceleration performance, the system will choose to close the rear wing. Although the vehicle speed is high, closing the rear wing can significantly reduce air resistance, thereby optimizing the acceleration efficiency. Additionally, since the vehicle speed has not reached the second preset vehicle speed, it means that the vehicle has not entered the high-speed driving state where downforce must be provided. Therefore, in this case, even if the rear wing is closed, the vehicle remains in a safe state and does not affect driving safety. In summary, by introducing acceleration as an auxiliary judgment condition, the system can dynamically adjust the state of the rear wing within a specific speed range. Specifically, within the medium speed range where the vehicle speed is greater than the first preset vehicle speed but has not reached the second preset vehicle speed, although there is a certain need to open the rear wing, if the vehicle is in an accelerating state, the system will preferentially choose to close the rear wing to reduce air resistance and ensure the best balance between acceleration performance and driving experience. At the same time, since the vehicle speed has not reached the high vehicle speed where downforce must be provided, the vehicle still maintains a safe state. This can not only provide the necessary downforce when needed but also maximize the overall performance of the vehicle during acceleration.
[0080] It can be understood that the first preset vehicle speed is used to distinguish between low-speed driving and medium-speed driving that may require a certain amount of downforce, and the second preset vehicle speed is used to define the high-speed driving where the vehicle must provide downforce. When the vehicle speed is less than or equal to the first preset vehicle speed, the rear wing is closed to reduce unnecessary air resistance and energy consumption. When the vehicle speed is greater than the first preset vehicle speed and less than or equal to the second preset vehicle speed, the vehicle begins to enter the speed range where a certain amount of downforce is required but has not reached the level where downforce must be provided. Within this speed range, if the vehicle is accelerating, the system will choose to close the rear wing to optimize the acceleration performance; if the vehicle is in a constant-speed driving state or decelerating, the system will choose to open the rear wing to provide appropriate downforce. In addition, opening the rear wing to provide additional resistance is also beneficial for vehicle deceleration and optimizing the deceleration performance. When the vehicle speed reaches or exceeds the second preset vehicle speed, the vehicle enters the high-speed driving state. At this time, the vehicle's demand for downforce increases significantly, and the rear wing is opened to provide higher stability and controllability to ensure driving safety.
[0081] It can also be understood that controlling the opening and closing of the spoiler based on speed and based on environmental information can be carried out simultaneously or in steps. For example, it can first be determined based on vehicle speed information whether there is a need to open the spoiler. If it is determined based on vehicle speed information that there is a need to open the spoiler (such as being greater than or equal to a second preset vehicle speed), then it is further determined according to environmental information whether the environmental conditions require or allow the spoiler to be opened. If the environmental conditions do not require or allow the spoiler to be opened (such as a large distance between obstacles, rainy or snowy weather, or a low-temperature environment), then the spoiler is actively closed or kept in the closed state; if the environmental conditions require or allow the spoiler to be opened (such as a small distance between obstacles, sunny day and suitable temperature), then the spoiler is actively opened or kept in the open state. If it is determined based on vehicle speed information that there is no need to open the spoiler (such as the vehicle speed being less than or equal to a first preset vehicle speed), then the spoiler is directly closed or kept in the closed state without further judging the environmental information. It can also be the other way around. First, it is determined based on environmental information whether the environmental conditions require or allow the spoiler to be opened. If the environmental conditions require or allow the spoiler to be opened, then it is further determined based on vehicle speed information whether there is a need to open the spoiler. If there is no need to open the spoiler, then the spoiler is kept closed or closed. If there is a need to open the spoiler, then the spoiler is controlled to open; if the environmental conditions do not require or allow the spoiler to be opened, then the spoiler is directly kept closed or closed without further judging the vehicle speed information. In addition, controlling the opening and closing of the spoiler simultaneously based on speed and environmental information is also an effective strategy. In this case, the system will evaluate the vehicle speed and environmental information simultaneously and comprehensively consider the results of both to determine the state of the spoiler. For example, when the vehicle speed reaches or exceeds the second preset vehicle speed, the system will simultaneously monitor environmental information (such as weather conditions, temperature, etc.). If bad weather (such as rainy or snowy weather) or a low-temperature environment is detected, even if the vehicle speed meets the requirement for opening the spoiler, the system will choose to close the spoiler to avoid potential safety risks or mechanical failures. On the contrary, if the vehicle speed is low (less than or equal to the first preset vehicle speed), but the environmental conditions are very favorable (such as sunny day and suitable temperature), the system may choose to continue to keep the spoiler in the closed state because there is no need for additional downforce at this time. Through this synchronous evaluation method, the system can make the optimal decision in the shortest time, ensuring that the spoiler operation not only meets the current speed requirements but also adapts to changes in environmental conditions. This method not only improves the response speed and accuracy of the system but also provides better stability and safety under complex and changeable driving conditions. This double-layer or multi-layer judgment mechanism ensures that under different driving conditions, the operation of the spoiler can be more accurate and efficient. Whether judging based on vehicle speed first or environmental information first, or evaluating simultaneously, it can effectively improve the reliability of the system and the user experience, ensuring that the vehicle can maintain the best performance in various driving environments.In this way, the system can not only provide the necessary downforce at high speeds to enhance stability and handling, but also reduce air resistance and energy consumption at low speeds or in adverse environments, optimizing the overall driving experience.
[0082] In some embodiments, the first preset vehicle speed is between 30 km / h and 50 km / h; and / or, the second preset vehicle speed is between 80 km / h and 100 km / h. In these embodiments, by reasonably setting the ranges of the first preset vehicle speed and the second preset vehicle speed, the system can dynamically adjust the state of the rear wing in different speed ranges. The first preset vehicle speed is between 30 km / h and 50 km / h. Within this range, the system can effectively distinguish between low-speed driving on urban roads or congested sections and medium-speed driving that requires a certain amount of downforce. Closing the rear wing reduces unnecessary air resistance and energy consumption. Especially in the urban environment with frequent starts and stops, this design helps to improve fuel economy and extend the service life of mechanical components. The second preset vehicle speed is between 80 km / h and 100 km / h. Within this range, the system can accurately identify that the vehicle enters the high-speed driving state, ensuring that sufficient downforce is provided to enhance the stability and handling of the vehicle when driving on highways or expressways. Opening the rear wing not only improves the safety of the vehicle at high speeds, but also significantly improves the driving experience, especially when performing high-speed turning or lane-changing operations. By setting a reasonable range of preset vehicle speeds, the system can achieve the best aerodynamic performance and energy consumption management under different driving conditions, ensuring the efficient operation and safety of the vehicle in various speed ranges.

The rear wing assembly 100 includes a rear wing 1, a detection device 2, an adjustment component 3, and a control device 4. The detection device 2 obtains the environmental information of the vehicle; the adjustment component 3 is drivingly connected to the rear wing 1 to adjust the opening state and the closing state of the rear wing 1; the control device 4 is electrically connected to the detection device 2 and the adjustment component 3 respectively to control the operation of the adjustment component 3 according to the environmental information.
[0084] In these embodiments, the tail wing 1 is responsible for providing downforce under different driving conditions to enhance the stability and controllability of the vehicle. The detection device 2 is used to obtain the environmental information of the vehicle, such as vehicle speed, acceleration, weather conditions, temperature, obstacle distance, etc. By monitoring this information in real time, the system can make intelligent decisions to adjust the state of the tail wing 1. The adjustment component 3 is drivingly connected to the tail wing 1 and is responsible for adjusting the opening and closing states of the tail wing 1. According to the instructions issued by the control device 4, the adjustment component 3 dynamically opens or closes the tail wing 1, thereby optimizing the aerodynamic performance and energy consumption performance of the vehicle. The control device 4 is electrically connected to the detection device 2 and the adjustment component 3 respectively and plays a core control role. It calculates the optimal state of the tail wing 1 based on the environmental information provided by the detection device 2 and sends corresponding control signals to the adjustment component 3 to achieve precise control of the tail wing 1. Through this design, the tail wing assembly 100 can dynamically adjust the state of the tail wing 1 under different driving conditions, ensuring that the vehicle can maintain the best performance in various driving environments.
[0085] It can be understood that the detection device 2 for obtaining the environmental information of the vehicle may include a vehicle speed sensor (measuring the wheel speed to calculate the vehicle speed), a temperature sensor (monitoring the ambient temperature), a weather sensor (such as a rain sensor and a humidity sensor for detecting rain and snow weather), an obstacle sensor (such as an ultrasonic radar, a lidar (LiDAR), or a camera system for detecting obstacles around the vehicle and their distances), and GPS and map data (providing the vehicle position information and combining with the map data to judge the current road section type). The adjustment component 3 is responsible for driving the lifting, contraction, expansion, and angle adjustment of the tail wing 1. Its structure includes a power source (providing power output, such as a motor, a hydraulic or pneumatic system. When the motor is used as the power source, a Hall sensor can be set on the output shaft of the motor to accurately calculate the position of the tail wing 1 by detecting the number of rotations of the output shaft of the motor) and a transmission mechanism (such as a link mechanism, a gear transmission mechanism, etc.). The adjustment component 3 is composed of a power source and a transmission mechanism. The power source provides the necessary power output, and the transmission mechanism transmits the power of the power source to the tail wing 1 to achieve multi-dimensional adjustment of the tail wing 1. The control device 4 is responsible for receiving the data of the detection device 2 and sending instructions to the adjustment component 3. The control device 4 can be an ECU (electronic control unit, a traditional control system, mature and reliable, easy to integrate), or a domain controller (centralizing the management of multiple subsystems, simplifying the architecture, and improving flexibility), or an independent controller (designed specifically for the tail wing 1 control system to ensure the response speed and accuracy). Through these specific implementation forms, the tail wing assembly 100 can dynamically adjust the state of the tail wing 1 under different driving conditions, ensuring that the vehicle can maintain the best performance in various driving environments.
