[0028] If the duration for which the vehicle speed information is less than the third vehicle speed threshold is greater than a preset time threshold, the action mode is determined to be off;

[0029] If the vehicle speed information changes from being greater than the second vehicle speed threshold to being less than the first vehicle speed threshold, and the duration of being less than the first vehicle speed threshold is greater than a preset time threshold, then the action mode is determined to be off.

[0030] Optionally, detecting abnormal operation of the fairing includes:

[0031] If an abnormal operation signal of the fairing is received from the fairing monitoring device during the monitoring of the fairing's operation, it is determined that the abnormal operation of the fairing has been detected.

[0032] Optionally, based on the abnormal handling strategy of the fairing, an abnormal handling operation is performed on the fairing, including: obtaining the abnormal handling strategy of the fairing, wherein the abnormal handling strategy is to control the fairing action by increasing torque;

[0033] Based on the current environmental information, a target torque greater than the preset torque is determined;

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] How to control the fairing after it is installed on a vehicle to reduce driving resistance is a technical problem that urgently needs to be solved by those skilled in the art.

[0055] In this invention, analysis shows that vehicle resistance is related to vehicle speed. Therefore, the fairing can be opened or closed based on vehicle speed information to reduce vehicle resistance.

[0056] In addition, to improve the intelligent control of the fairing, it can be equipped with a welcome function. When the user uses the remote key to start the vehicle, the fairing can repeatedly open and close to welcome the user.

[0057] In addition, to protect the fairing from damage by snow accumulation or to prevent rainwater from flowing into the vehicle through the open fairing during rain, it is necessary to determine whether to open or close the fairing based on the weather conditions in order to protect the vehicle.

[0058] Based on the above, one embodiment of the present invention provides a fairing control method, device, electronic device, and vehicle. In this invention, a corresponding fairing action strategy can be determined based on at least one of the vehicle state and current environmental information. Then, according to the fairing action strategy, the fairing action is controlled by a drive motor pulling a hinge device connected to the fairing, ensuring that the fairing control is adapted to the current vehicle operating conditions and environment, thus improving the accuracy of fairing control. Furthermore, if abnormal fairing action is detected during the fairing action, an abnormality handling operation is performed on the fairing based on the fairing abnormality handling strategy, ensuring the safety and reliability of the fairing and preventing damage to it.

[0059] One embodiment of the present invention provides a method for controlling a fairing. A schematic diagram of the fairing in this invention can be found in the following reference. Figure 1 , Figure 1 The fairing can be configured into any shape according to actual needs, and its location can be customized, such as on the front bumper or other front-end positions. Normally, the fairing is closed; if it needs to be opened, it should be... Figure 1The indicated running direction is open.

[0060] The fairing control method in this embodiment can be applied to a controller, such as an electronic control unit. The controller can control the opening and closing of the fairing.

[0061] Reference Figure 2 The fairing control method may include:

[0062] S11. Determine the vehicle information of the target vehicle.

[0063] In this embodiment, the target vehicle is the vehicle for which the fairing movement control needs to be performed. It can be any model or brand of vehicle equipped with a fairing. The fairing can be, for example, an active front bumper fairing.

[0064] In practical applications, when opening the fairing, it is necessary to ensure that the current state of the vehicle allows the fairing to be opened, that is, opening the fairing at this time will not have a safety impact on the vehicle.

[0065] The state of a vehicle can be analyzed from two aspects: the vehicle itself and the environment in which it is located. In this embodiment, it is necessary to determine the vehicle information of the target vehicle, which includes at least one of the vehicle state and the current environmental information.

[0066] The vehicle status includes both start-up and driving states. In practical applications, the start-up state refers to the state where the vehicle receives a start signal but the engine is not yet running. When a user wants to use the vehicle, they can start it by pressing the start button on the remote key. If a start signal is received from the remote key of the target vehicle, the vehicle status of the target vehicle is determined to be start-up. In addition to the remote key, the controller can also send a start signal if it detects the owner is within a preset range of the vehicle. Subsequent examples will use the remote key sending a start signal as an example.

[0067] Driving state refers to the state in which the engine of a vehicle is running. If the engine of the target vehicle is detected to be running, the vehicle state of the target vehicle is determined to be driving state.

[0068] While in motion, the vehicle can be in any gear except parking, such as forward or reverse. If it is in forward or reverse, the vehicle is moving; if it is in parking, the vehicle is temporarily stopped.

[0069] The current environmental information of this invention may include weather information, such as cloudy, rainy, snowy, etc.

[0070] When determining current environmental information, weather sensors can be used to detect weather conditions to obtain current environmental information. For example, a rain sensor can directly detect whether it is raining and the amount of rainfall if it is raining. Alternatively, a temperature sensor can detect temperature, and a humidity sensor can detect humidity. If the temperature and humidity meet the conditions for rain (e.g., low temperature and high humidity), it is considered raining; if the temperature and humidity meet the conditions for snowing, it is considered snowing. Furthermore, the results of other sensors can be combined to determine whether it is snowing. For example, if the temperature and humidity meet the conditions for snowing, and cameras such as radar mounted on the vehicle's exterior are covered, it is considered snowing.

[0071] In addition, a light sensor can be used to detect whether it is a cloudy day.

[0072] In this embodiment, the opening of the fairing in rainy or snowy weather has a safety impact on the vehicle. For example, in heavy rain, if the fairing is opened, rainwater will flow into the vehicle through the open fairing, affecting vehicle safety. In snowy weather, if the fairing is opened, it may be affected by snow accumulation, preventing it from opening properly. Forcing it to open may cause damage to the fairing. Cloudy weather has little impact on fairing opening; therefore, the weather information in this embodiment mainly refers to rain and snow.

[0073] It should be noted that when the fairing is opened, the triggering condition may be only the vehicle status, or it may be the vehicle status combined with the current and current environmental information, or it may be only the current environmental information. Therefore, in this embodiment, the vehicle information is limited to at least one of the vehicle status and the current environmental information.

[0074] S12. Determine the fairing action strategy corresponding to the vehicle information.

[0075] In practical applications, different fairing action strategies are used when the vehicle status and current environmental information are different, which will be introduced separately below.

[0076] 1. When the vehicle is in the start state, determine that the fairing action strategy of the target vehicle is a welcoming action strategy.

[0077] To expand the functionality of the fairing, a welcome mode was configured. When the vehicle is first started, i.e., when the user unlocks the vehicle with the remote key, the fairing can be opened, closed, reopened, and closed again to welcome the user. Since the vehicle is not yet moving, the brief opening and closing of the fairing at this time is less affected by rain or snow; therefore, only the vehicle's status needs to be considered, regardless of the current environmental conditions.

[0078] If the vehicle is in the "start" state, then the fairing action strategy of the target vehicle is determined to be a "welcome action strategy".

[0079] The welcoming action strategy includes: the fairing opening angle is a first angle, and the opening and closing operations are repeatedly performed.

[0080] In this embodiment, the number of times the deflector is repeatedly opened and closed can be configured according to actual needs, such as two, three, four, or other times. When opening, the time required for the deflector to go from closed to normal opening is 2 seconds, and the time required for it to go from open to closed is also 2 seconds.

[0081] In welcome mode, when the fairing is opened, the opening angle is the first angle, which can be configured according to actual conditions, such as 60°.

[0082] 2. When the vehicle is in a driving state and the weather information is a preset rainy weather, the fairing action strategy of the target vehicle is determined to be the fairing stop action strategy.

[0083] In this embodiment, during heavy rain, the probability of rainwater flowing into the vehicle through the fairing is relatively high, while during light or moderate rain, the probability of rainwater flowing into the vehicle through the fairing is relatively low. Therefore, the preset rainy weather in this embodiment is heavy rain.

[0084] In heavy rain, if a vehicle is in motion, it means the vehicle is either moving or temporarily stopped. To protect the vehicle during heavy rain, the fairing should be closed. In this case, the fairing's operating strategy is called the fairing stop strategy. The fairing stop strategy involves closing the fairing.

[0085] When the vehicle is in a driving state and the weather information is not the preset rainy weather, that is, when the vehicle is less affected by the weather, the factors affecting the opening or closing of the fairing are mainly the vehicle itself. In order to avoid wind resistance when the vehicle is driving, the fairing can be opened or closed according to the vehicle speed information. At this time, the fairing action strategy is a vehicle speed-related action strategy.

[0086] In the speed-related action strategy, the fairing opening angle varies depending on the vehicle speed. For example, at higher vehicle speeds, a larger fairing opening angle results in better drag reduction, while at lower vehicle speeds, a larger fairing opening angle does not significantly improve drag reduction; therefore, a smaller opening angle is acceptable.

[0087] S13. According to the fairing action strategy, the fairing is controlled to move by the drive motor pulling the hinge device connected to the fairing. If abnormal fairing action is detected during the fairing action, abnormal handling operation is performed on the fairing based on the fairing abnormal handling strategy.

[0088] Specifically, once the fairing action strategy is determined, the fairing can be opened or closed according to that strategy.

[0089] In practical applications, in order to control the opening or closing of the fairing, it is necessary to configure corresponding components to drive the fairing to move. In this embodiment, a hinge device can be used to drive the fairing to move. In addition, a transmission device or the like can also be used to drive the fairing to move.

[0090] When the hinge device is in motion, it needs to be driven by a drive motor. In this embodiment, the model and size of the drive motor can be selected according to the actual situation.

[0091] Because the different action strategies of the fairing result in different processes for the drive motor to drive the fairing, they will be described separately below.

[0092] 1. The deflector action strategy is a welcoming action strategy.

[0093] In this mode, users can be welcomed by repeatedly opening and closing the fairing. In practical applications, if the current weather is not snowing, the force required to open and close the fairing is relatively small. In this embodiment, the force required to open and close the fairing can be determined based on actual scenario testing, thereby determining the torque of the drive motor. In practical applications, a fixed torque can be used, i.e., a preset torque controls the drive motor to drive the hinge device, causing the hinge device to move the fairing and repeatedly perform the opening and closing operations; wherein, the angle at which the fairing opens each time is the first angle.

[0094] In welcome mode, when the hinge device drives the fairing to move, if the fairing is currently closed, it opens the fairing to the first angle, which is 60°, and then controls the fairing to close, then opens it again, and closes it again.

[0095] 2. The fairing action strategy is a fairing stop action strategy.

[0096] This strategy indicates that the fairing is not suitable to be opened at present and needs to be closed. In practical applications, this scenario could be snowfall, heavy rain, etc., where the fairing needs to be closed to protect the safety of both the fairing and the vehicle. In this case, the fairing can be closed by the drive motor pulling the hinge device connected to it.

[0097] 3. The fairing action strategy is a speed-related action strategy.

[0098] If the fairing's action strategy is speed-dependent, it means the vehicle is currently in motion or temporarily stopped. In this case, the vehicle's drag should be considered, as drag is related to vehicle speed. When the fairing's action strategy is speed-dependent, refer to... Figure 3According to the aforementioned fairing action strategy, the fairing action is controlled by a drive motor pulling a hinge device connected to the fairing, including the following steps:

[0099] S21. Detect the speed information of the target vehicle.

[0100] In this embodiment, the Power Domain Control Unit (PDCU) detects vehicle speed information, and the vehicle speed signal is transmitted to the PDCU. The PDCU then transmits the vehicle speed signal to the Electronic Control Unit.

[0101] S22. Determine the action mode corresponding to the vehicle speed information.

[0102] The action method includes opening or closing. In this embodiment, it is necessary to determine whether the fairing is currently open or closed. If the vehicle speed is low or the vehicle speed is decreasing, the driving resistance is reduced, so the fairing can be closed. If the vehicle speed is high, the fairing can be opened in order to reduce the driving resistance, and the opening angle can be controlled according to the vehicle speed.

[0103] Specifically as follows:

[0104] 1. If the duration of the vehicle speed information being between the first vehicle speed threshold and the second vehicle speed threshold is greater than a preset time threshold, the action mode is determined to be open.

[0105] Wherein, the second vehicle speed threshold is greater than the first vehicle speed threshold, the first vehicle speed threshold can be, for example, 60 km / h, the second vehicle speed threshold can be, for example, 80 km / h, and the preset time threshold can be, for example, 1 minute.

[0106] If the current vehicle speed is between 60 and 80 km / h, and the duration within this speed range is greater than 1 minute, it indicates that the current vehicle speed is stable, and fairing control can be performed based on this speed. Within this speed range, the vehicle speed is moderate, and the fairing can be opened at the second angle (e.g., 30°).

[0107] 2. If the duration for which the vehicle speed information is greater than the second vehicle speed threshold is greater than a preset time threshold, the action mode is determined to be "open".

[0108] Specifically, if the vehicle speed is greater than 80 km / h and the duration is greater than 1 minute, it indicates that the vehicle is in a high-speed stable state. In this case, the opening angle of the fairing is the first angle, which is 60°. Compared to the opening angle of 30° when the vehicle speed is in the range of 60-80 km / h, the opening angle increases with the vehicle speed, which can better reduce driving resistance.

[0109] 3. If the duration for which the vehicle speed information is less than the third vehicle speed threshold is greater than a preset time threshold, the action mode is determined to be off.

[0110] In this embodiment, the third vehicle speed threshold is 40km / h. That is, if the vehicle speed is less than 40km / h for more than 1 minute, whether or not the fairing is opened will not have a significant impact on reducing drag. Therefore, the fairing can be closed.

[0111] 4. If the vehicle speed information changes from being greater than the second vehicle speed threshold to being less than the first vehicle speed threshold, and the duration of being less than the first vehicle speed threshold is greater than a preset time threshold, then the action mode is determined to be off.

[0112] Specifically, if the vehicle speed decreases from above 80 km / h to below 60 km / h, and the decrease lasts for more than 1 minute, it indicates that the vehicle is slowing down. In this case, opening the fairing has little effect on reducing driving resistance, and the fairing can be closed.

[0113] S23. The flow guide is controlled to move according to the aforementioned action method by means of a drive motor pulling a hinge device connected to the flow guide.

[0114] In this embodiment, after the action mode is determined based on step S22, the flow guide can be controlled to perform the corresponding action according to the action mode.

[0115] Specifically, when the vehicle is in motion, if the speed is ≥60km / h and <80km / h, the speed signal is transmitted to the power control unit. The power control unit collects the signal and transmits it to the electronic control unit. The electronic control unit detects that the speed is ≥60km / h and <80km / h for 1 minute (this strategy prevents the fairing from opening and closing frequently). The electronic control unit sends an opening signal to the active front bumper fairing and simultaneously sends a fairing opening reminder signal to the display screen. The active front bumper fairing drive motor controls the hinge to open the fairing. The opening angle is 30° and the fairing opening time is 2 seconds. After opening, the fairing is fixed at 30°.

[0116] If the vehicle speed is ≥80km / h and continues for 1 minute (this strategy prevents the fairing from opening and closing frequently), the opening angle is 60°, the fairing opening time is 2 seconds, and after opening, the fairing is fixed at 60°.

[0117] When the vehicle speed is ≤40km / h, the vehicle speed signal is transmitted to the electronic control unit. The power control unit collects the signal and transmits it to the electronic control unit. If the electronic control unit detects that the vehicle speed is ≤40km / h for 1 minute, it sends a closing signal to the active front bumper fairing and sends a fairing closing reminder signal to the display screen. The active front bumper fairing drive motor controls the hinge to close the fairing. The fairing takes 2 seconds to close and then remains closed until the opening conditions are met.

[0118] When the vehicle speed decreases from more than 80 km / h to less than 60 km / h and remains so for 1 minute, the active front bumper fairing drive motor controls the hinge to close the fairing. The fairing takes 2 seconds to close and remains closed until the opening conditions are met, at which point it opens again.

[0119] During the aforementioned fairing operation, to improve reliability, the fairing's movement progress is monitored in real time to detect any abnormal movements. Monitoring can be performed using a fairing monitoring device, which can be a controller connected to the fairing. This controller has a built-in monitoring program that monitors whether the fairing is moving as required. If the monitoring detects that the fairing is not moving as required, an abnormal fairing movement signal, such as a self-test signal, is sent to the electronic control unit (ECU). The ECU can then confirm the abnormal fairing movement, which could be something like a jam.

[0120] In this embodiment, if an abnormal operation signal of the fairing is received from the fairing monitoring device during the monitoring of the fairing operation, it is determined that the abnormal operation of the fairing has been detected.

[0121] After detecting abnormal operation of the fairing, an abnormal operation will be performed on the fairing based on the abnormal handling strategy of the fairing to ensure normal operation of the fairing.

[0122] Specifically, refer to Figure 4 It can include:

[0123] S31. Obtain the abnormal handling strategy of the deflector.

[0124] Specifically, the abnormal handling strategy can be configured according to the actual situation. In actual application, if the fairing cannot operate normally, such as failing to open to the set angle or failing to close normally, it may be due to snow accumulation or obstacles blocking the way. In this case, the fairing operation can be controlled by increasing the torque.

[0125] The torque-increasing method involves increasing the torque of the drive motor, thereby increasing the force output by the drive motor, which in turn increases the force output to the hinge device, and increases the force that drives the fairing to move, thus overcoming the obstruction of snow or obstacles.

[0126] S32. Based on the current environmental information, determine a target torque that is greater than a preset torque.

[0127] Specifically, when pulling the fairing by increasing torque, it is necessary to determine the value of the increased torque. In this embodiment, the target torque to be increased can be determined according to the severity of the external environment.

[0128] Specifically, if the sensor detects that it is snowing, the severity of the snow accumulation can be determined through image detection and other methods. If the snow thickness is large, the target torque value will be large; if the snow thickness is small, the target torque value can be small. The specific configuration can be made by technicians according to the actual situation.

[0129] If an obstacle prevents the fairing from opening properly, the size of the obstacle can be detected. If the obstacle is large, the target torque value will be large; if the obstacle is small, the target torque value will be small. In this case, a voice prompt can be given to the user so that the user can remove the obstacle in time to ensure the safety of the fairing.

[0130] S33. Output the target torque to the drive motor, so that the drive motor drives the fairing to move through the hinge device, so that the fairing opens to the maximum angle and then closes.

[0131] After the target torque is determined in step S32, the target torque can be output to the drive motor to control the fairing to open to the maximum angle and then close. If it needs to be opened again, it can be opened according to the actual situation.

[0132] In this embodiment, a corresponding fairing action strategy can be determined based on at least one of the vehicle status and current environmental information. Then, according to the fairing action strategy, the fairing is controlled to move by the drive motor pulling the hinge device connected to the fairing, ensuring that the fairing control is adapted to the current vehicle operation and environment, thus improving the accuracy of fairing control. Furthermore, if abnormal fairing movement is detected during the fairing action, an anomaly handling operation is performed on the fairing based on the anomaly handling strategy, ensuring the safety and reliability of the fairing and preventing damage.

[0133] As can be seen from the above, this invention can achieve the following functions: active front bumper fairing welcome function, active opening and closing and angle control function during driving, jamming function, snow removal function, and rainproof function. See details below. Figure 5.

[0134] Under the welcoming function:

[0135] 1. Preset conditions:

[0136] The vehicle is running;

[0137] 2. Triggering condition: Starting the vehicle while carrying the remote key.

[0138] 3. Main event flow:

[0139] When starting the vehicle with the key, the start signal is transmitted to the power control unit. The power control unit sends a start signal to the electronic control unit for judgment, which drives the motor to pull the hinge device to open and close the active front bumper fairing by 60°. The opening time is 2 seconds, the closing time is 2 seconds, and the opening and closing is repeated twice for 8 seconds to achieve the welcome function.

[0140] The preset conditions for the active opening and closing and angle control function during driving are: the car is in motion, the engine is running, including all gears.

[0141] The powertrain control unit (PDCU) sends the vehicle speed signal to the electronic control unit (ECU), which then controls the opening and closing of the active front bumper fairing and displays a reminder on the screen.

[0142] Under the functions of jamming and snow clearing:

[0143] Preset conditions:

[0144] 1. The vehicle is running;

[0145] 2. Triggering conditions: Start the vehicle with the remote key, but the fairing is not opened to the required angle.

[0146] 3. Main event flow:

[0147] When starting the vehicle with the key, similar to the welcome mode, if the active front bumper fairing fails to open or close properly due to jamming, the fairing monitoring device sends a self-test signal to the electronic control unit (ECU). The ECU then sends a torque increase command to the active front bumper fairing, allowing the fairing to move from its current position to its maximum open position and simultaneously to its fully closed position, thus achieving normal opening and closing. If it fails to open or close properly, the ECU sends a fault signal to the display screen to indicate the fault, requiring manual resolution.

[0148] Waterproofing in rainy weather:

[0149] Preset conditions:

[0150] 1. The power mode is in the "power on" state, including all settings;

[0151] 2. Triggering conditions: The rain sensor detects rain and rainfall.

[0152] 3. Main event flow:

[0153] During driving, when the vehicle speed has reached the condition for the fairing to open and it is raining, the rain sensor determines whether it is light rain or heavy rain by detecting the amount of rain received. The rain sensor transmits a signal to the electronic control unit. In heavy rain, the fairing executes the closing signal and does not execute the opening signal issued by the vehicle speed.

[0154] This embodiment achieves active opening and closing by seamlessly integrating the active front bumper fairing with the front bumper during vehicle operation, thereby reducing wind resistance and fuel consumption, increasing range, improving performance, and enhancing customer satisfaction.

[0155] In addition, the active front bumper fairing features a welcoming, opening and closing, locking, snow clearing, and rain waterproofing design, creating a variety of scenarios to enhance the vehicle's technological feel.
