Description

Technical Field

[0001] This application relates to the field of vehicles, and more specifically, to a method, apparatus, vehicle, and storage medium for controlling a front bumper fairing in the field of vehicles. Background Technology

[0002] An aerodynamic deflector is an important aerodynamic component in vehicle design, used to optimize airflow and improve vehicle performance and efficiency.

[0003] In the prior art, fairings are installed in different parts of the vehicle, including: front bumper fairings located below the front bumper at the front of the vehicle, roof fairings located at the top and rear of the vehicle, side skirt fairings located below the side doors of the vehicle, and rear spoiler fairings located on the trunk lid or roof of the vehicle, etc.

[0004] However, in the existing technology, the front bumper fairing of vehicles is usually installed in a fixed manner. Fixed-installation fairings have obvious defects in adapting to various operating conditions of the vehicle, resulting in a poor user experience. Summary of the Invention

[0005] This application provides a method, apparatus, vehicle, and storage medium for controlling a front bumper fairing. The method can improve the flexibility of vehicle control, reduce the user's operational burden, improve the vehicle's intelligence level, and enhance the user's driving experience.

[0006] Firstly, a method for controlling a front bumper fairing is provided. The method includes: acquiring vehicle operating data and the current state of the vehicle's front bumper fairing; if the current state of the front bumper fairing is closed, determining, based on the operating data, whether the vehicle meets preset conditions for opening the front bumper fairing; if the vehicle meets the preset conditions for opening the front bumper fairing, controlling the front bumper fairing to open; if the current state of the front bumper fairing is open, determining, based on the operating data, whether the vehicle meets preset conditions for closing the front bumper fairing; and if the vehicle meets the preset conditions for closing the front bumper fairing, controlling the front bumper fairing to close.

[0007] In the above technical solution, by analyzing vehicle operating data and the current state of the front bumper fairing, the system automatically controls the front bumper fairing to open when the preset conditions for opening are met, and automatically controls it to close when the preset conditions for closing are met. This achieves automatic control of the front bumper fairing's opening and closing, improving vehicle control flexibility, automating the control of the front bumper fairing, reducing the user's operational burden, and enhancing the vehicle's intelligence level. By automatically adjusting the state of the front bumper fairing based on different operating data, the system ensures optimal vehicle performance in various scenarios, improving the user's driving experience.

[0008] In conjunction with the first aspect, in some possible implementations, when the operating data is the vehicle speed, it is determined whether the vehicle meets the preset conditions for opening the front bumper fairing based on the operating data, including: when the vehicle speed is greater than or equal to the preset vehicle speed, it is determined whether the first duration for which the vehicle speed is greater than or equal to the preset vehicle speed is greater than the first preset duration; when it is determined that the first duration is greater than the first preset duration, it is determined that the vehicle meets the preset conditions for opening the front bumper fairing.

[0009] In the above technical solution, the front bumper fairing is activated when the vehicle speed exceeds a preset speed. The activation of the fairing reduces wind resistance, thereby reducing fuel consumption and improving vehicle stability. Furthermore, the front bumper fairing is only activated after the vehicle speed exceeds the preset speed for a specified duration. This improves the accuracy of fairing activation control and avoids erroneous activation due to vehicle speed fluctuations, where the speed exceeds the preset speed only at a certain moment and then rapidly decelerates to below it. This prevents frequent opening and closing of the front bumper fairing.

[0010] In combination with the first aspect and the above implementation methods, in some possible implementation methods, when the running data is the vehicle speed, based on the running data, it is determined whether the vehicle meets the preset conditions for closing the front bumper fairing, including: when the vehicle speed is less than the preset vehicle speed, it is determined whether the second duration of the vehicle speed being less than the preset vehicle speed is greater than the second preset duration; when it is determined that the second duration is greater than the second preset duration, it is determined that the vehicle meets the preset conditions for closing the front bumper fairing.

[0011] In the above technical solution, the front bumper fairing is closed promptly when the vehicle speed is lower than the preset speed. Closing the front bumper fairing increases downforce at the front, improving the vehicle's stability and handling at low speeds. Furthermore, when the vehicle speed is lower than the preset speed, the front bumper fairing is only controlled to close after a second duration of the speed being lower than the preset speed exceeds a second preset duration, thus avoiding frequent closure of the front bumper fairing.

[0012] In conjunction with the first aspect and the above implementation methods, in some possible implementation methods, when the preset vehicle speed includes a first preset vehicle speed and a second preset vehicle speed, and the second preset vehicle speed is greater than the first preset vehicle speed, if it is determined that the vehicle meets the preset conditions for opening the front bumper fairing, controlling the front bumper fairing to open includes: when the vehicle speed is greater than the first preset vehicle speed and less than the second preset vehicle speed, determining a first opening degree and controlling the front bumper fairing to open based on the first opening degree; when the vehicle speed is greater than the second preset vehicle speed, determining a second opening degree and controlling the front bumper fairing to open based on the second opening degree; wherein, the second opening degree is greater than the first opening degree.

[0013] In the above technical solution, by setting different preset vehicle speeds—a first preset speed and a second preset speed—and controlling the opening of the front bumper fairing according to the vehicle speed, more refined aerodynamic management is achieved. Specifically, in the low-speed range where the vehicle speed is greater than the first preset speed but less than the second preset speed, controlling the front bumper fairing to open to the first opening degree can moderately reduce wind resistance and improve fuel economy. In the high-speed range where the vehicle speed is greater than the second preset speed, controlling the front bumper fairing to open to a second opening degree greater than the first opening degree can further reduce wind resistance and significantly improve fuel economy and high-speed driving stability.

[0014] In combination with the first aspect and the above implementation methods, in some possible implementation methods, when the operating data is the temperature of at least one component in the front compartment of the vehicle, it is determined whether the vehicle meets the preset conditions for opening or closing the front bumper fairing based on the operating data, including: if it is determined that the temperature is greater than or equal to the preset temperature, it is determined whether the third duration for which the temperature of at least one component is greater than the preset temperature is greater than the third preset duration; if it is determined that the third duration is greater than the third preset duration, it is determined that the vehicle meets the preset conditions for opening the front bumper fairing.

[0015] In the above technical solution, by monitoring the temperature of the front cabin components in real time, abnormal component temperature conditions can be detected promptly. When the temperature reaches the preset temperature, the front bumper fairing is opened in a timely manner to increase the cooling airflow in the front cabin, which can effectively cool the components in the front cabin and prevent them from overheating and being damaged. By monitoring the duration for which the temperature exceeds the preset temperature, the opening of the front bumper fairing is only determined when the duration of the temperature exceeding the preset temperature is greater than a third preset time. This avoids misjudgment due to short-term temperature fluctuations, improves the accuracy of judgment, and enhances the stability and reliability of the front bumper fairing opening control.

[0016] In combination with the first aspect and the above implementation methods, in some possible implementation methods, when the operating data is the temperature of at least one component in the front compartment of the vehicle, determining whether the vehicle meets the preset conditions for closing the front bumper fairing based on the operating data includes: if the temperature is lower than the preset temperature, determining whether the fourth duration for which the temperature of at least one component is lower than the preset temperature is greater than the fourth preset duration; if it is determined that the fourth duration is greater than the fourth preset duration, determining that the vehicle meets the preset conditions for closing the front bumper fairing.

[0017] In the above technical solution, the temperature of the front cabin components is monitored in real time. When the temperature of the components drops below a preset temperature, the front bumper fairing is promptly closed to reduce unnecessary cooling airflow into the front cabin and prevent over-cooling of the components. By monitoring the duration of the temperature being below the preset temperature, the front bumper fairing is only deemed necessary to be closed when the duration of the temperature being below the preset temperature exceeds a fourth preset duration. This avoids misjudgments due to short-term temperature fluctuations, improves the accuracy of judgment, and enhances the stability and reliability of the front bumper fairing opening control.

[0018] In combination with the first aspect and the above-described implementations, in some possible implementations, the vehicle's front compartment includes: an air conditioning compressor, and at least one of the powertrain components.

[0019] In summary, this application achieves automated control of the front bumper fairing by real-time monitoring of vehicle speed, the temperature of the front air conditioning compressor, and powertrain components, thereby determining whether the vehicle meets the preset conditions for opening or closing the fairing. Specifically, opening the fairing at higher speeds reduces wind resistance, thus lowering fuel consumption and improving vehicle stability. Closing the fairing promptly as speed decreases increases downforce at the front, improving low-speed stability and handling. Opening the fairing when temperatures are high increases front airflow, effectively cooling components and preventing overheating damage. Closing the fairing when temperatures drop reduces unnecessary cooling airflow, preventing overcooling of components.

[0020] Secondly, a device for controlling a front bumper fairing is provided. The device includes: an acquisition module for acquiring vehicle operating data and the current state of the vehicle's front bumper fairing; a first judgment module for determining, based on the operating data, whether the vehicle meets preset conditions for opening the front bumper fairing when the current state of the front bumper fairing is closed; a first control module for controlling the front bumper fairing to open when it is determined that the vehicle meets the preset conditions for opening the front bumper fairing; a second judgment module for determining, based on the operating data, whether the vehicle meets preset conditions for closing the front bumper fairing when the current state of the front bumper fairing is open; and a second control module for controlling the front bumper fairing to close when it is determined that the vehicle meets the preset conditions for closing the front bumper fairing.

[0021] In conjunction with the second aspect, in some possible implementations, when the running data is the vehicle speed, the first judgment module is specifically used to determine whether the first duration for which the vehicle speed is greater than or equal to the preset speed is greater than the first preset duration when the vehicle speed is greater than or equal to the preset speed; and if it is determined that the first duration is greater than the first preset duration, determine that the vehicle meets the preset conditions for opening the front bumper fairing.

[0022] In combination with the second aspect and the above implementation methods, in some possible implementation methods, when the running data is the vehicle speed, the second judgment module is specifically used to determine whether the second duration of the vehicle speed being less than the preset speed is greater than the second preset duration when the vehicle speed is less than the preset speed; and if it is determined that the second duration is greater than the second preset duration, determine that the vehicle meets the preset condition of closing the front bumper fairing.

[0023] In conjunction with the above-mentioned implementation methods of the second aspect, in some possible implementation methods, the preset vehicle speed includes a first preset vehicle speed and a second preset vehicle speed. The first control module is specifically used to: determine a first opening degree when the vehicle speed is greater than the first preset vehicle speed and less than the second preset vehicle speed, and control the front bumper fairing to open based on the first opening degree; determine a second opening degree when the vehicle speed is greater than the second preset vehicle speed, and control the front bumper fairing to open based on the second opening degree; wherein, the second opening degree is greater than the first opening degree.

[0024] In combination with the second aspect and the above implementation methods, in some possible implementation methods, when the operating data is the temperature of at least one component in the front compartment of the vehicle, the first judgment module is specifically used to: determine whether the third duration for which the temperature of at least one component is greater than the preset temperature is greater than the third preset duration when the temperature is determined to be greater than or equal to the preset temperature; and determine that the vehicle meets the preset conditions for opening the front bumper fairing when the third duration is determined to be greater than the third preset duration.

[0025] In combination with the second aspect and the above implementation methods, in some possible implementation methods, when the operating data is the temperature of at least one component in the front compartment of the vehicle, the second judgment module is specifically used to determine whether the fourth duration for which the temperature of at least one component is lower than the preset temperature is greater than the fourth preset duration when the temperature is lower than the preset temperature; and if it is determined that the fourth duration is greater than the fourth preset duration, determine that the vehicle meets the preset condition for closing the front bumper fairing.

[0026] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the front compartment of the vehicle includes at least one of the following components: an air conditioning compressor and a powertrain assembly.

[0027] Thirdly, a vehicle is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the vehicle to perform the methods of the first aspect or any possible implementation thereof.

[0028] Fourthly, a computer program product is provided, comprising: computer program code, which, when run on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof.

[0029] Fifthly, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof. Attached Figure Description

[0036] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0037] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] In the prior art, fairings are installed in different parts of the vehicle, including: front bumper fairings located below the front bumper, roof fairings located at the top and rear of the vehicle, side skirt fairings located below the side doors, and rear spoiler fairings located on the trunk lid or roof, etc., to improve the vehicle's power performance.

[0039] However, in the existing technology, the front bumper fairing of vehicles is usually installed in a fixed manner. Fixed fairings are not flexible enough and have obvious defects in adapting to various operating conditions of the vehicle, resulting in a poor user experience.

[0040] This application proposes a method for controlling the front bumper fairing, which enables the front bumper fairing to be automatically opened or closed based on the vehicle's operating data during driving, thereby improving the user's driving experience.

[0041] Figure 1 This is a schematic flowchart illustrating a method for controlling a front bumper fairing according to an embodiment of this application. This method is applied to vehicles, specifically to the vehicle's electronic control unit.

[0042] For example, such as Figure 1 As shown, the method 100 includes:

[0043] Step 101: Obtain the vehicle's operating data and the current status of the vehicle's front bumper fairing;

[0044] Step 102: If the front bumper fairing is currently in the closed state, determine whether the vehicle meets the preset conditions for opening the front bumper fairing based on the operating data.

[0045] Step 103: If the vehicle meets the preset conditions for opening the front bumper fairing, control the front bumper fairing to open.

[0046] Step 104: If the front bumper fairing is currently in the open state, determine whether the vehicle meets the preset conditions for closing the front bumper fairing based on the operating data.

[0047] Step 105: If the vehicle meets the preset conditions for closing the front bumper fairing, control the front bumper fairing to close.

[0048] exist Figure 1 In the illustrated embodiment, by acquiring vehicle operating data and the current state of the front bumper fairing, the system automatically controls the front bumper fairing to open when the preset conditions for opening the fairing are met, and automatically controls it to close when the preset conditions for closing the fairing are met. This achieves automatic control of the front bumper fairing's opening and closing, improving vehicle control flexibility, realizing automated control of the front bumper fairing, reducing the user's operational burden, and enhancing the vehicle's intelligence level. By automatically adjusting the state of the front bumper fairing based on different operating data, the system ensures the vehicle maintains optimal performance in various scenarios, improving the user's driving experience.

[0049] The following is about Figure 1 The specific implementation methods of each step in the illustrated embodiments are described in detail below:

[0050] In step 101, vehicle operating data refers to various data generated during vehicle operation, including vehicle speed, engine speed, vehicle acceleration, steering angle, ambient temperature, and the temperature of relevant components within the vehicle. This data can be acquired in real time through sensors and monitoring systems inside the vehicle. Ambient temperature typically refers to the temperature outside the vehicle. The ambient temperature outside the vehicle has a certain impact on the temperature of relevant components during vehicle operation. For example, when the vehicle travels to a high-temperature area, the excessively high ambient temperature may cause the temperature of relevant components to rise excessively.

[0051] A front bumper fairing is a component installed near the front bumper of a vehicle, typically below it. It alters the direction and speed of airflow under the vehicle, generating additional downforce to reduce lift at the front, enhancing grip and stability. The front bumper fairing can be either open or closed.

[0052] In this embodiment, the front bumper fairing is specifically an active front bumper fairing, which includes a drive motor, a hinge, and a fairing. The drive motor controls the opening or closing of the fairing by controlling the hinge.

[0053] In step 102, when the current state of the front bumper fairing is open, the open front bumper fairing will change the airflow at the front of the vehicle and have a certain impact on the vehicle. At this time, it can be determined whether the vehicle meets the preset conditions for closing the front bumper fairing based on the vehicle's operating data.

[0054] In step 103, the front bumper fairing can be opened or closed by rotating left or right around an axis perpendicular to the ground.

[0055] It's understandable that the front bumper fairing experiences the greatest wind resistance when closed, resulting in the greatest drag. When the front bumper fairing is open, the area exposed to wind resistance decreases, thus reducing the drag on the vehicle.

[0056] Specifically, when it is determined that the vehicle meets the preset conditions for opening the front bumper fairing, an opening signal can be sent to the front bumper fairing so that the front bumper fairing can be opened by controlling the hinge through the drive motor upon receiving the opening signal.

[0057] In one possible implementation, when the operating data is the vehicle speed, the system determines whether the vehicle meets the preset conditions for opening the front bumper fairing based on the operating data, including: when the vehicle speed is greater than or equal to a preset vehicle speed, determining whether the first duration for which the vehicle speed is greater than or equal to the preset vehicle speed is greater than a first preset duration; and when it is determined that the first duration is greater than the first preset duration, determining that the vehicle meets the preset conditions for opening the front bumper fairing.

[0058] The preset speed is the minimum speed at which the vehicle needs to open the front bumper fairing to reduce vehicle drag.

[0059] When the running data is vehicle speed, it can be determined whether the vehicle speed is greater than the preset vehicle speed, and whether the first duration of the vehicle speed being greater than the preset vehicle speed is greater than the first preset duration, in order to determine whether the vehicle meets the preset conditions for opening the front bumper fairing.

[0060] Specifically, if the vehicle speed is greater than a preset speed and the first duration of the speed being greater than the preset speed is greater than a first preset duration, it can be determined that the vehicle meets the preset conditions for opening the front bumper fairing.

[0061] Figure 2 This is a flowchart of a front bumper fairing based on vehicle speed control provided in an embodiment of this application.

[0062] For example, such as Figure 2As shown, a vehicle may include an Electronic Stability Program (ESP). ESP monitors vehicle operating data through various sensors, specifically including: a vehicle speed sensor to monitor vehicle speed, a lateral acceleration sensor to monitor vehicle lateral acceleration, and a steering angle sensor to monitor the steering wheel angle, etc.

[0063] The ESP sends the monitored vehicle speed to the Powertrain Control Unit (PDCU), which then transmits the vehicle speed to the Electronic Control Unit (ECU). The ECU receives the vehicle speed from the PDCU and controls the opening of the front bumper fairing based on the vehicle speed.

[0064] For example, with a preset vehicle speed of 60 km / h and a first duration of 1 minute, the electronic control unit starts monitoring the first duration of the vehicle speed ≥ 60 km / h when it detects that the vehicle speed is ≥ 60 km / h. When the first duration is greater than 1 minute (this strategy prevents the fairing from opening and closing frequently), it sends an opening signal to the active front bumper fairing. The drive motor of the active front bumper fairing controls the hinge to open the fairing based on the opening signal.

[0065] In the above method, the front bumper fairing is activated when the vehicle speed exceeds a preset speed. The activation of the fairing reduces wind resistance, thereby reducing fuel consumption and improving vehicle stability. Furthermore, the front bumper fairing is only activated after the vehicle speed exceeds the preset speed for a specified duration. This improves the accuracy of fairing activation control and avoids erroneous activation due to vehicle speed fluctuations, where the speed exceeds the preset speed only at a certain moment and then rapidly decelerates to below it. This also prevents frequent opening and closing of the front bumper fairing.

[0066] In one possible implementation, the preset vehicle speed includes a first preset vehicle speed and a second preset vehicle speed. The second preset vehicle speed is greater than the first preset vehicle speed. Controlling the opening or closing of the front bumper fairing based on the operating data includes: when the vehicle speed is greater than the first preset vehicle speed but less than the second preset vehicle speed, determining a first opening degree and controlling the front bumper fairing to open based on the first opening degree; when the vehicle speed is greater than the second preset vehicle speed, determining a second opening degree and controlling the front bumper fairing to open based on the second opening degree; wherein the second opening degree is greater than the first opening degree.

[0067] The angle when the front bumper fairing is closed is recorded as zero degrees. The angle between the position of the front bumper fairing after it is opened and its closed position is called the opening degree of the front bumper fairing.

[0068] It is understandable that the larger the opening of the front bumper fairing, the smaller the area of ​​the front bumper fairing that bears the wind resistance, and the less resistance the vehicle will experience when driving.

[0069] Because vehicles experience varying levels of drag at different speeds, the higher the speed, the greater the drag, and consequently, the greater the fuel consumption. To reduce vehicle drag at all speeds, the opening of the front bumper fairing can be determined based on the speed.

[0070] The preset vehicle speeds specifically include a first preset speed and a second preset speed, dividing the speed at which the fairing needs to be opened into two stages. The second preset speed is greater than the first preset speed. Specifically, the speed at which the fairing needs to be opened is divided into two stages: greater than or equal to the first preset speed and less than the second preset speed, and greater than or equal to the second preset speed. Different opening degrees can be preset for these two stages. After determining that the vehicle meets the preset conditions for opening the front bumper fairing, the target stage of the vehicle speed is determined, and the preset opening degree corresponding to the target stage is set as the opening degree to control the front bumper fairing opening.

[0071] Specifically, a first opening degree is set for the stage where the vehicle speed is greater than or equal to a first preset speed and less than a second preset speed, and a second opening degree is set for the stage where the vehicle speed is greater than or equal to the second preset speed, with the second opening degree being greater than the first opening degree. When it is determined that the vehicle speed is greater than or equal to the first preset speed and less than the second preset speed, the first opening degree is determined, and the fairing is controlled to open based on the first opening degree. When it is determined that the vehicle speed is greater than or equal to the second preset speed, the second opening degree is determined, and the fairing is controlled to open based on the second opening degree.

[0072] For example, the first opening degree is 30 degrees, the second opening degree is 60 degrees, the first preset vehicle speed is 60 km / h, and the second preset vehicle speed is 80 km / h. Assuming the vehicle speed is 70 km / h, which is greater than the first preset speed of 60 km / h but less than the second preset speed of 80 km / h, the first opening degree is determined to be 30 degrees, and the front bumper fairing is controlled to open based on this first opening degree. Assuming the vehicle speed is 90 km / h, which is greater than the second preset speed of 80 km / h, the second opening degree is determined to be 60 degrees, and the front bumper fairing is controlled to open based on this second opening degree.

[0073] Understandably, when the preset vehicle speed specifically includes a first preset vehicle speed and a second vehicle speed, determining whether the vehicle meets the preset conditions for opening the front bumper fairing specifically includes: determining whether the vehicle speed is greater than or equal to the first preset vehicle speed, and whether a first duration greater than or equal to the first preset vehicle speed is greater than a first preset duration. If the vehicle speed is greater than or equal to the first preset vehicle speed, and a first duration greater than or equal to the first preset vehicle speed is greater than the first preset duration, then the vehicle is determined to meet the preset conditions for opening the front bumper fairing. Alternatively, determining whether the vehicle speed is greater than or equal to the second preset vehicle speed, and whether a first duration greater than or equal to the second preset vehicle speed is greater than the first preset duration. If the vehicle speed is greater than or equal to the second preset vehicle speed, and a first duration greater than or equal to the second preset vehicle speed is greater than the first preset duration, then the vehicle is determined to meet the preset conditions for opening the front bumper fairing.

[0074] The above method achieves more refined aerodynamic management by setting different preset vehicle speeds: a first preset speed and a second preset speed, and controlling the opening of the front bumper fairing according to the vehicle speed. Specifically, in the low-speed range where the vehicle speed is greater than the first preset speed but less than the second preset speed, controlling the front bumper fairing to open to the first opening degree can moderately reduce wind resistance and improve fuel economy. In the high-speed range where the vehicle speed is greater than the second preset speed, controlling the front bumper fairing to open to a second opening degree greater than the first opening degree can further reduce wind resistance and significantly improve fuel economy and high-speed driving stability.

[0075] In some embodiments, when the operating data is the vehicle speed, and the preset speed includes a first preset speed and a second speed, if the front bumper fairing is currently in an open state, it can be determined whether the opening degree of the front bumper fairing is less than the second opening degree. If it is determined that the opening degree of the front bumper fairing is less than the second opening degree, it can be determined again based on the operating data whether the vehicle meets the preset conditions for opening the front bumper fairing. Specifically, it can be determined that the vehicle meets the preset conditions for reopening the front bumper fairing when the vehicle speed is greater than or equal to the second preset speed, and the first duration of the second preset speed is greater than the first preset duration. At this time, the opening degree of the front bumper fairing is the second opening degree. If it is determined that the opening degree of the front bumper fairing is greater than or equal to the second opening degree, it can be determined based on the operating data whether the vehicle meets the preset conditions for closing the front bumper fairing.

[0076] In one possible implementation, when the operating data is the temperature of at least one component in the front compartment of the vehicle, the vehicle is judged based on the operating data to determine whether the vehicle meets the preset conditions for opening or closing the front bumper fairing, including: if the temperature is determined to be greater than or equal to the preset temperature, determining whether the third duration for which the temperature of at least one component is greater than the preset temperature is greater than the third preset duration; if the third duration is determined to be greater than the third preset duration, determining that the vehicle meets the preset conditions for opening the front bumper fairing.

[0077] The front compartment of a vehicle is the engine compartment, which typically contains multiple components.

[0078] It is understandable that at least some of the components located in the vehicle's front compartment will generate heat during vehicle operation, causing their temperature to gradually rise. Alternatively, when the vehicle is operating in harsh environments, such as deserts, gravel roads, or high-temperature areas, the temperature of some components in the front compartment will gradually increase as the vehicle moves.

[0079] Each component in the vehicle's front compartment is equipped with a corresponding temperature sensor to monitor the temperature of each component. Based on the temperature detected by the sensors, the vehicle determines whether it currently meets the preset conditions for opening the front bumper fairing, and controls the front bumper fairing to open after confirming that the vehicle currently meets the preset conditions for opening the front bumper fairing.

[0080] It is understandable that the components in the front compartment operate within a normal temperature range. When the component's temperature equals or exceeds a certain temperature, the component is at risk of overheating and damage. The preset temperature is the lowest temperature at which the component is at risk of overheating.

[0081] When the operating data is the temperature of at least one component in the vehicle's front compartment, it can be determined whether the component's temperature is greater than or equal to a preset temperature, and whether the third duration for which the component's temperature is greater than or equal to the preset temperature is greater than a third preset duration, to determine whether the vehicle meets the preset conditions for opening the front bumper fairing. The third preset duration is used to improve the stability of the judgment.

[0082] Specifically, if the temperature is greater than or equal to a preset temperature, and the third duration of the component temperature being greater than or equal to the preset temperature is greater than a third preset duration, the vehicle can be determined to meet the preset conditions for opening the front bumper fairing.

[0083] Understandably, when the front bumper fairing is open, more air can enter the vehicle's front compartment to reduce the temperature of the components in the front compartment.

[0084] In one possible implementation, the vehicle's front compartment includes at least one component, such as an air conditioning compressor or a powertrain assembly.

[0085] The air conditioning compressor is the compressor for the vehicle's onboard air conditioning system, and the powertrain components include: engine, transmission, differential, and other parts.

[0086] When the component temperature is the same as the air conditioner compressor temperature, the preset temperature is the lowest temperature at which the air conditioner compressor is at risk of overheating.

[0087] Figure 3 This is a flowchart of a front bumper fairing based on air conditioning compressor temperature control provided in an embodiment of this application.

[0088] For example, such as Figure 3 As shown, the air conditioning compressor temperature sensor transmits the air conditioning compressor temperature to the power control unit, which in turn transmits the air conditioning compressor temperature to the electronic control unit. The electronic control unit then controls the opening of the front bumper fairing based on the air conditioning compressor temperature.

[0089] For example, the lowest temperature at which the air conditioning compressor is prone to overheating is 50 degrees Celsius, i.e., the preset temperature is 50 degrees Celsius, and the third preset duration is 5 minutes. When the electronic control unit detects that the temperature of the air conditioning compressor is ≥50 degrees Celsius, it starts monitoring the third duration of the air conditioning compressor temperature being ≥50 degrees Celsius. When the third duration is greater than 5 minutes (this strategy prevents the deflector from opening and closing frequently), it sends an opening signal to the active front bumper deflector. The drive motor of the active front bumper deflector controls the hinge to open the deflector based on the opening signal.

[0090] When the temperature of a component is the same as that of a powertrain component (such as an engine), the preset temperature is the lowest temperature at which the engine is at risk of overheating.

[0091] Figure 4 This is a flowchart of a front bumper fairing based on powertrain component temperature control provided in an embodiment of this application.

[0092] For example, such as Figure 4 As shown, the powertrain system transmits the temperature of the powertrain components to the power control unit, which in turn transmits the temperature of the powertrain components to the electronic control unit. The electronic control unit then controls the opening of the front bumper fairing based on the temperature of the powertrain components.

[0093] For example, the lowest temperature at which a powertrain component (e.g., the engine) is prone to overheating is 100 degrees Celsius, i.e., the preset temperature is 100 degrees Celsius, and the third preset duration is 5 minutes. When the electronic control unit detects that the temperature of the powertrain component is ≥100 degrees Celsius, it starts monitoring the third duration of the powertrain component temperature being ≥100 degrees Celsius. When the third duration is greater than 5 minutes (this strategy prevents the fairing from opening and closing frequently), it sends an opening signal to the active front bumper fairing. The drive motor of the active front bumper fairing controls the hinge to open the fairing based on the opening signal.

[0094] In the above method, by monitoring the temperature of the front cabin components in real time, abnormal component temperature can be detected in a timely manner. When the temperature reaches the preset temperature, the front bumper fairing is opened promptly to increase the cooling airflow in the front cabin, which can effectively cool the components in the front cabin and prevent them from overheating and being damaged. By monitoring the duration for which the temperature exceeds the preset temperature, the opening of the front bumper fairing is only determined when the duration of the temperature exceeding the preset temperature is greater than a third preset time. This avoids misjudgment due to short-term temperature fluctuations, improves the accuracy of judgment, and enhances the stability and reliability of the front bumper fairing opening control.

[0095] In step 104, when the current state of the front bumper fairing is closed, the vehicle maintains its original performance. At this time, in order to improve the performance of the vehicle, it can be determined whether the vehicle currently meets the preset conditions for opening the front bumper fairing based on the vehicle's operating data.

[0096] In step 105, when it is determined that the vehicle meets the preset conditions for closing the front bumper fairing, a closing signal can be sent to the front bumper fairing so that the front bumper fairing, upon receiving the closing signal, will close by controlling the hinge through the drive motor.

[0097] In one possible implementation, when the operating data is the vehicle speed, the system determines whether the vehicle meets the preset conditions for closing the front bumper fairing based on the operating data. This includes: if the vehicle speed is less than a preset speed, determining whether the second duration for which the vehicle speed is less than the preset speed is greater than a second preset duration; and if the second duration is determined to be greater than the second preset duration, determining that the vehicle meets the preset conditions for closing the front bumper fairing.

[0098] When the operating data is the vehicle speed, with the front bumper fairing open, it can be determined whether the vehicle speed is less than the preset speed and whether the second duration of the speed being less than the preset speed is greater than the second preset duration, in order to determine whether the vehicle meets the preset conditions for closing the front bumper fairing.

[0099] Specifically, when the front bumper fairing is open, the vehicle can be determined to meet the preset conditions for closing the front bumper fairing if the vehicle speed is less than a preset speed and the second duration of the speed being less than the preset speed is greater than the second preset duration.

[0100] like Figure 2 As shown, when the front bumper fairing is open, the electronic control unit controls the closing of the front bumper fairing based on the vehicle speed transmitted by the PDCU.

[0101] For example, with a preset vehicle speed of 60 km / h and a second duration of 2 minutes, the electronic control unit starts monitoring the second duration of the vehicle speed when it detects that the vehicle speed is less than 60 km / h. When the second duration is greater than 2 minutes (this strategy prevents the fairing from opening and closing frequently), it sends a closing signal to the active front bumper fairing. The drive motor of the active front bumper fairing controls the hinge to close the fairing based on the closing signal.

[0102] In some embodiments, when the operating data is vehicle speed, before determining whether the vehicle meets the preset conditions for opening or closing the front bumper fairing, it is also necessary to determine that the vehicle's engine is running and the vehicle's gear can be in any gear.

[0103] In some embodiments, when the preset vehicle speed includes a first preset vehicle speed and a second preset vehicle speed, determining whether the vehicle meets the preset condition for closing the front bumper fairing specifically includes: determining whether the vehicle speed is less than the first preset vehicle speed, and whether a second duration for which the vehicle speed is less than the first preset vehicle speed is greater than a second preset duration. If the vehicle speed is less than the first preset vehicle speed, and the second duration for which the vehicle speed is less than the first preset vehicle speed is greater than the second preset duration, then the vehicle is determined to meet the preset condition for closing the front bumper fairing. Alternatively, determining whether the vehicle speed is less than the second preset vehicle speed, and whether a second duration for which the vehicle speed is less than the second preset vehicle speed is greater than the second preset duration. If the vehicle speed is less than the second preset vehicle speed, and the second duration for which the vehicle speed is less than the second preset vehicle speed is greater than the second preset duration, then the vehicle is determined to meet the preset condition for closing the front bumper fairing.

[0104] In some embodiments, when the preset vehicle speed includes a first preset vehicle speed and a second preset vehicle speed, controlling the front bumper fairing to close based on the operating data includes: when the fairing is currently in the open state, if the vehicle speed is less than the first preset vehicle speed, controlling the fairing to close completely; if the vehicle speed is less than the second preset vehicle speed but greater than the first preset vehicle speed, controlling the fairing to close to a first opening degree.

[0105] In the above method, the front bumper fairing is closed promptly when the vehicle speed is lower than the preset speed. Closing the front bumper fairing increases downforce at the front, improving the vehicle's stability and handling at low speeds. Furthermore, when the vehicle speed is lower than the preset speed, the front bumper fairing is only controlled to close after a second duration of the speed being lower than the preset speed exceeds a second preset duration, thus avoiding frequent closure of the front bumper fairing.

[0106] In one possible implementation, when the operating data is the temperature of at least one component in the front compartment of the vehicle, determining whether the vehicle meets the preset conditions for closing the front bumper fairing based on the operating data includes: if the temperature is lower than the preset temperature, determining whether the fourth duration for which the temperature of at least one component is lower than the preset temperature is greater than the fourth preset duration; if it is determined that the fourth duration is greater than the fourth preset duration, determining that the vehicle meets the preset conditions for closing the front bumper fairing.

[0107] When the front bumper fairing is in the open state, when the operating data is the temperature of at least one component in the front compartment of the vehicle, it can be determined whether the temperature of the component is lower than a preset temperature, and whether the fourth duration for which the temperature of the component is lower than the preset temperature is greater than a fourth preset duration, so as to determine whether the vehicle meets the preset conditions for closing the front bumper fairing.

[0108] Specifically, when the front bumper fairing is open, the vehicle can be determined to meet the preset conditions for closing the front bumper fairing if the temperature of the component is lower than a preset temperature and the fourth duration for which the temperature of the component is lower than the preset temperature is greater than a fourth preset duration.

[0109] When the component is an air conditioning compressor, such as Figure 3 As shown, when the front bumper fairing is open, the electronic control unit controls the front bumper fairing to close based on the temperature of the air conditioning compressor transmitted by the PDCU.

[0110] For example, the preset temperature is 50 degrees Celsius, and the fourth duration is 10 minutes. When the electronic control unit detects that the temperature of the air conditioning compressor is <50 degrees Celsius, it starts monitoring the air conditioning compressor temperature for the fourth duration of <50 degrees Celsius. When the fourth duration is greater than 10 minutes (this strategy prevents the fairing from opening and closing frequently), it sends a closing signal to the active front bumper fairing. The drive motor of the active front bumper fairing controls the hinge to close the fairing based on the closing signal.

[0111] In some embodiments, when the component is an air conditioning compressor, it is also necessary to determine that the vehicle is in a running state before determining whether the vehicle meets the preset conditions for opening or closing the front bumper fairing.

[0112] When the component is a powertrain component, such as Figure 4As shown, when the front bumper fairing is open, the electronic control unit controls the closure of the front bumper fairing based on the temperature of the powertrain components transmitted by the PDCU.

[0113] For example, the preset temperature is 100 degrees Celsius, and the fourth duration is 10 minutes. When the electronic control unit detects that the temperature of the powertrain components is <100 degrees Celsius, it starts monitoring the powertrain components for a fourth duration when the temperature is <100 degrees Celsius. When the fourth duration is greater than 10 minutes (this strategy prevents the fairing from opening and closing frequently), it sends a closing signal to the active front bumper fairing. The drive motor of the active front bumper fairing controls the hinge to close the fairing based on the closing signal.

[0114] In some embodiments, when the component is a powertrain component, before determining whether the vehicle meets the preset conditions for opening or closing the front bumper fairing, it is also necessary to determine that the vehicle power mode is in a powered-on state, and the vehicle gear can be any of the gears.

[0115] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 As shown, the electronic control unit can simultaneously send an opening signal to the active front bumper fairing and a fairing opening reminder signal to the display screen, so that the vehicle displays a message indicating that the fairing is open to the user. Alternatively, the electronic control unit can simultaneously send a closing signal to the active front bumper fairing and a fairing closing reminder signal to the display screen, so that the vehicle displays a message indicating that the fairing is closed to the user.

[0116] In some embodiments, priorities can be set for the two control methods. Specifically, when some components in the vehicle's front compartment are overheated, the front bumper fairing remains open even if the vehicle's speed is lower than a preset speed. This means that controlling the front bumper fairing's opening based on component temperature has a higher priority than controlling its closing based on vehicle speed. Conversely, when the vehicle's speed is greater than or equal to a preset speed, the front bumper fairing remains open even if the temperature of the components in the front compartment is lower than a preset temperature. Again, this means that controlling the front bumper fairing's opening based on vehicle speed has a higher priority than controlling its closing based on component temperature.

[0117] In the above method, the temperature of the front cabin components is monitored in real time. When the temperature of the components drops below a preset temperature, the front bumper fairing is closed in a timely manner to reduce unnecessary cooling airflow into the front cabin and prevent over-cooling of the components. By monitoring the duration of the temperature being below the preset temperature, the front bumper fairing is only determined to need to be closed when the duration of the temperature being below the preset temperature exceeds a fourth preset duration. This avoids misjudgments due to short-term temperature fluctuations, improves the accuracy of the judgment, and enhances the stability and reliability of the front bumper fairing opening control.

[0118] In summary, this application achieves automated control of the front bumper fairing by real-time monitoring of vehicle speed, the temperature of the front air conditioning compressor, and powertrain components, thereby determining whether the vehicle meets the preset conditions for opening or closing the fairing. Specifically, opening the fairing at higher speeds reduces wind resistance, thus lowering fuel consumption and improving vehicle stability. Closing the fairing promptly as speed decreases increases downforce at the front, improving low-speed stability and handling. Opening the fairing when temperatures are high increases front airflow, effectively cooling components and preventing overheating damage. Closing the fairing when temperatures drop reduces unnecessary cooling airflow, preventing overcooling of components.

[0119] Figure 5 This is a schematic diagram of a device for controlling a front bumper fairing provided in an embodiment of this application.

[0120] For example, such as Figure 5 As shown, the device 500 includes:

[0121] The acquisition module 501 is used to acquire the vehicle's operating data and the current status of the vehicle's front bumper fairing;

[0122] The first judgment module 502 is used to determine, based on the operating data, whether the vehicle meets the preset conditions for opening the front bumper fairing when the current state of the front bumper fairing is closed.

[0123] The first control module 503 is used to control the front bumper fairing to open when it is determined that the vehicle meets the preset conditions for opening the front bumper fairing.

[0125] The second control module 505 is used to control the front bumper fairing to close when it is determined that the vehicle meets the preset conditions for closing the front bumper fairing.

[0126] In one possible implementation, when the running data is the vehicle speed, the first judgment module 502 is specifically used to determine whether the first duration for which the vehicle speed is greater than or equal to the preset speed is greater than the first preset duration when the vehicle speed is greater than or equal to the preset speed; and if the first duration is determined to be greater than the first preset duration, determine that the vehicle meets the preset conditions for opening the front bumper fairing.

[0127] In one possible implementation, when the running data is the vehicle speed, the second judgment module 504 is specifically used to determine whether the second duration of the vehicle speed being less than the preset speed is greater than the second preset duration when the vehicle speed is less than the preset speed; and if the second duration is determined to be greater than the second preset duration, determine that the vehicle meets the preset condition for closing the front bumper fairing.

[0128] In one possible implementation, the preset vehicle speed includes a first preset vehicle speed and a second preset vehicle speed.

[0130] In one possible implementation, when the operating data is the temperature of at least one component in the front compartment of the vehicle, the second judgment module 504 is specifically used to determine whether the fourth duration for which the temperature of at least one component is lower than the preset temperature is greater than the fourth preset duration when the temperature is lower than the preset temperature; and if the fourth duration is determined to be greater than the fourth preset duration, determine that the vehicle meets the preset condition for closing the front bumper fairing.
