Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to an electric tail wing ice-breaking method, apparatus, equipment, vehicle, and storage medium. Background Technology
[0002] Currently, an increasing number of electric vehicles are equipped with electric rear wings to reduce air resistance. These electric rear wings can effectively reduce downflow pressure, decrease the drag coefficient, and increase wheel grip, thus providing users with a better driving experience. However, below zero degrees Celsius, electric rear wings often freeze and fail to open properly. Therefore, it is necessary to develop an ice-breaking strategy to address this issue in low-temperature environments and ensure that the electric rear wings can open normally.
[0003] In related technologies, the electric rear wing function is typically activated by a Hall effect sensor located in the drive mechanism. This sensor detects the number of Hall effect points to determine if the wing is frozen. If frozen, the motor's duty cycle is increased, causing the wing to move and impact between opening and closing to break the ice. This ice-breaking method only activates the wing when needed. However, if the wing is completely frozen at low temperatures for an extended period, it may fail to deploy effectively, resulting in ice-breaking failure. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0043] It should be noted that in the description of the embodiments of this application, the terms "first," "second," etc., are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited. For example, the first object can be one or more.
[0044] The electric tail fin ice-breaking method, apparatus, equipment, vehicle, and storage medium provided in the embodiments of this application will be described exemplarily below with reference to the accompanying drawings.
[0045] Figure 1 This is one of the flowcharts illustrating an electric tail fin ice-breaking method provided in an embodiment of this application, as shown below. Figure 1 As shown, the method includes:
[0046] S101. Determine the ambient temperature of the vehicle.
[0047] It should be noted that the vehicle in the embodiments of this application can be any type of automobile, such as an electric vehicle or a gasoline-powered vehicle.
[0048] In some embodiments, a temperature sensor can be used to collect the ambient temperature of the vehicle's current location.
[0049] In some embodiments, the ambient temperature at the vehicle's current location can be determined based on a temperature sensor built into the vehicle.
[0050] S102. If the ambient temperature is determined to be lower than the set temperature, determine the drive duty cycle of the target motor of the vehicle.
[0051] In some embodiments, if it is determined that the ambient temperature at the current location of the vehicle is lower than a set temperature, then the drive duty cycle of the target motor used to drive the electric rear wing to open and close is determined.
[0052] It should be noted that the set temperature can be adapted based on the actual application, and this application embodiment does not impose specific limitations on it. For example, the set temperature is zero degrees Celsius.
[0053] In some embodiments, if the ambient temperature at the current location of the vehicle is determined to be less than zero degrees Celsius, the drive duty cycle of the target motor used to drive the electric tail wing to open and close is determined by a pre-set drive duty cycle determination strategy.
[0054] It's important to note that the motor's duty cycle refers to the percentage of time the motor is energized within one cycle, expressed as a percentage. Typically, a motor's duty cycle ranges from 0% to 100%, where a 0% duty cycle means the motor is completely stopped, and a 100% duty cycle means the motor is running continuously. A higher duty cycle results in a faster motor speed; conversely, a lower duty cycle results in a slower motor speed.
[0055] S103. Based on the drive duty cycle, control the target motor to drive the electric rear wing of the vehicle to perform ice-breaking action.
[0056] In some embodiments, if the ambient temperature at the current location of the vehicle is determined to be lower than a set temperature, the drive duty cycle of the target motor used to drive the electric rear wing to open and close is determined by a pre-set drive duty cycle determination strategy, and then the target motor is automatically controlled to drive the electric rear wing of the vehicle to perform ice-breaking action based on the drive duty cycle.
[0057] In some embodiments, after the target motor drives the electric rear wing of the vehicle to perform an ice-breaking action for a set time, it can be determined whether the electric rear wing has successfully broken the ice. If it is determined that the electric rear wing has successfully broken the ice, the target motor is controlled to stop driving the electric rear wing.
[0058] In some embodiments, during the process of controlling the target motor to drive the electric rear wing of the vehicle to perform ice-breaking action, the success of ice-breaking by the electric rear wing can be detected in real time. If it is determined that the electric rear wing has successfully broken the ice, the target motor is controlled to immediately stop driving the electric rear wing.
[0059] It should be noted that the target motor drives the electric tail fin to perform the ice-breaking action, which can be understood as the target motor driving the electric tail fin to perform motion impact between opening and closing to break the ice.
[0060] In some embodiments, if the ambient temperature at the current location of the vehicle is determined to be less than zero degrees Celsius, the body controller is activated, and the target motor is used to drive the electric rear wing of the vehicle to perform ice-breaking action.
[0061] In some embodiments, if the ambient temperature at the vehicle's current location is determined to be greater than or equal to zero degrees Celsius, the body control is not activated, and the electric rear wing is not required to perform ice-breaking actions.
[0062] For example, Figure 2 This is a schematic diagram illustrating the opening and closing of an electric tail wing, as provided in an embodiment of this application. Figure 2 As shown, the electric tail fin deploys when it moves from the fully closed position 0 to the fully open position 1, and closes when it moves from the fully open position 1 to the fully closed position 0. The actions of deploying and closing the tail fin are the ice-breaking actions performed by the electric tail fin.
[0063] It is understood that, by automatically controlling the target motor to drive the electric rear wing of the vehicle to perform ice-breaking action when the ambient temperature of the vehicle is determined to be lower than the set temperature, the embodiments of this application can effectively prevent the electric rear wing from freezing solid in the low temperature environment for a long time, and fully ensure that the electric rear wing can be opened and closed normally.
[0064] It is understood that the electric rear wing ice-breaking method provided in this application embodiment can effectively prevent the electric rear wing from freezing solid in a low-temperature environment for a long time, thus preventing the electric rear wing from failing to effectively drive the electric rear wing to deploy and thus causing the electric rear wing to fail to break ice, by automatically controlling the target motor to drive the electric rear wing to perform ice-breaking action based on a determined drive duty cycle when the ambient temperature of the vehicle is determined to be lower than the set temperature.
[0065] In some embodiments, determining the drive duty cycle of the target motor of the vehicle when the ambient temperature is determined to be lower than a set temperature includes:
[0066] When the ambient temperature is determined to be lower than the set temperature, the accumulated ice value of the electric tail fin is determined, and the accumulated ice value is used to characterize the icing thickness level of the electric tail fin.
[0067] Based on the accumulated ice value, the drive duty cycle of the target motor of the vehicle is determined.
[0068] In this embodiment of the application, if it is determined that the ambient temperature of the vehicle is currently lower than the set temperature, the accumulated ice value of the vehicle's electric rear wing is determined. The accumulated ice value is used to characterize the ice thickness level of the vehicle's electric rear wing. Then, based on the accumulated ice value, the drive duty cycle of the target motor used to drive the electric rear wing to perform the ice-breaking action is determined. Then, based on the drive duty cycle, the target motor is controlled to drive the vehicle's electric rear wing to perform the ice-breaking action.
[0069] In some embodiments, if it is determined that the ambient temperature of the vehicle is currently below a set temperature, the icing thickness of the vehicle's electric rear spoiler can be detected, and the accumulated ice value of the electric rear spoiler can be determined based on the icing thickness. The greater the icing thickness, the greater the accumulated ice value.
[0070] For example, Figure 3 This is a second schematic flowchart illustrating an electric tail fin ice-breaking method provided in an embodiment of this application, as shown below. Figure 3 As shown, the method includes:
[0071] S301. Determine the ambient temperature of the vehicle.
[0072] S302. When it is determined that the ambient temperature is less than the set temperature, the accumulated ice value of the electric rear wing of the vehicle is determined, and the accumulated ice value is used to characterize the icing thickness level of the electric rear wing.
[0073] S303. Based on the accumulated ice value, determine the drive duty cycle of the target motor of the vehicle.
[0074] S304. Based on the drive duty cycle, control the target motor to drive the electric tail fin to perform ice-breaking action.
[0075] It is understood that the embodiments of this application determine the drive duty cycle of the target motor used to drive the electric tail fin to perform ice-breaking action by based on the accumulated ice value of the electric tail fin. This ensures that the target motor can effectively drive the electric tail fin to perform ice-breaking action based on the drive duty cycle, thereby achieving effective ice breaking by the electric tail fin.
[0076] In some embodiments, determining the drive duty cycle of the target motor of the vehicle based on the accumulated ice value includes:
[0077] Based on the accumulated ice value, a pre-built first mapping table is queried to obtain the drive duty cycle. The first mapping table is used to characterize the mapping relationship between the accumulated ice value and the drive duty cycle of the target motor.
[0078] In this embodiment of the application, after obtaining the accumulated ice value of the electric rear wing of the vehicle, the drive duty cycle of the target motor used to drive the electric rear wing to perform ice-breaking action can be obtained by querying a pre-constructed first mapping table based on the accumulated ice value. The first mapping table can characterize the mapping relationship between the accumulated ice value and the drive duty cycle.
[0079] In some embodiments, the mapping relationship between accumulated ice value and drive duty cycle can be pre-calibrated, and then a first mapping table can be constructed based on the calibrated mapping relationship.
[0080] For example, Figure 4 A schematic diagram of the first mapping table provided in the embodiments of this application, as shown below. Figure 4 As shown, when the accumulated ice value is less than I1, the corresponding drive duty cycle is 0%; when the accumulated ice value is between I1 and I2, the corresponding drive duty cycle is 20%; when the accumulated ice value is between I2 and I3, the corresponding drive duty cycle is 40%; when the accumulated ice value is between I3 and I4, the corresponding drive duty cycle is 60%; when the accumulated ice value is between I4 and I5, the corresponding drive duty cycle is 80%; and when the accumulated ice value is greater than I5, the corresponding drive duty cycle is 100%.
[0081] It is understandable that the greater the accumulated ice value, the greater the ice thickness of the electric tail fin, which requires a larger drive duty cycle to control the target motor to drive the electric tail fin to perform ice-breaking actions, thereby achieving effective ice breaking by the electric tail fin.
[0082] In some embodiments, controlling the target motor to drive the vehicle's electric rear wing to perform ice-breaking actions based on the drive duty cycle includes:
[0083] Based on the accumulated ice value, the driving time of the target motor is determined;
[0084] Based on the drive duty cycle and the drive time, the target motor is controlled to drive the electric tail fin to perform ice-breaking action.
[0085] In this embodiment of the application, after obtaining the accumulated ice value of the electric tail fin, the drive duty cycle and drive time of the target motor can be determined based on the accumulated ice value, and then the target motor can be controlled to drive the electric tail fin to perform ice-breaking action based on the drive duty cycle and drive time.
[0086] Understandably, after obtaining the drive duty cycle and drive time based on the accumulated ice value, the target motor can be controlled to drive the electric tail fin to continuously perform ice-breaking actions according to the drive duty cycle until the drive time is reached, at which point the target motor can be controlled to stop driving the electric tail fin.
[0087] For example, Figure 5 This is the third flowchart illustrating an electric tail fin ice-breaking method provided in this application embodiment, as shown below. Figure 5 As shown, the method includes:
[0088] S501. Determine the ambient temperature of the vehicle.
[0089] S502. When it is determined that the ambient temperature is less than the set temperature, the accumulated ice value of the electric rear wing of the vehicle is determined, and the accumulated ice value is used to characterize the icing thickness level of the electric rear wing.
[0090] S503. Based on the accumulated ice value, determine the drive duty cycle and drive time of the target motor of the vehicle.
[0091] S504. Based on the drive duty cycle and the drive time, control the target motor to drive the electric tail fin to perform ice-breaking action.
[0092] It is understood that the embodiments of this application determine the drive duty cycle and drive time of the target motor used to drive the electric tail fin to perform ice-breaking action by based on the accumulated ice value of the electric tail fin. This can ensure that the target motor can effectively drive the electric tail fin to successfully break ice based on the drive duty cycle and drive time, thereby achieving effective ice breaking by the electric tail fin.
[0093] In some embodiments, determining the drive time of the target motor based on the accumulated ice value includes:
[0094] Based on the accumulated ice value, a pre-constructed second mapping table is queried to obtain the driving time. The second mapping table is used to characterize the mapping relationship between the accumulated ice value and the driving time of the target motor.
[0095] In this embodiment of the application, after obtaining the accumulated ice value of the electric rear wing of the vehicle, a pre-constructed second mapping table can be queried based on the accumulated ice value to obtain the driving time of the target motor used to drive the electric rear wing to perform ice-breaking action, wherein the second mapping table can characterize the mapping relationship between the accumulated ice value and the driving time.
[0096] In some embodiments, the mapping relationship between accumulated ice value and driving time can be pre-calibrated, and then a second mapping table can be constructed based on the calibrated mapping relationship.
[0097] For example, Figure 6 A schematic diagram of the second mapping table provided in the embodiments of this application, as shown below. Figure 6 As shown, when the accumulated ice value is less than or equal to I1, the corresponding drive time is 0; when the accumulated ice value is I2, the corresponding drive time is T1; when the accumulated ice value is I3, the corresponding drive time is T2; when the accumulated ice value is I4, the corresponding drive time is T3; and when the accumulated ice value is I5, the corresponding drive time is T4. That is, when the accumulated ice value is greater than I1, the accumulated ice value and the drive time are positively correlated.
[0098] Understandably, the greater the accumulated ice value, the greater the ice thickness of the electric tail fin, which requires a longer drive time to control the target motor to drive the electric tail fin to perform ice-breaking actions, thereby achieving effective ice breaking by the electric tail fin.
[0099] In some embodiments, determining the accumulated ice value of the electric tail fin includes:
[0100] The icing condition of the electric tail fin is detected by an icing sensor, and the electrical signal detected by the icing sensor is obtained.
[0101] The accumulated ice value is determined based on the electrical signal.
[0102] In this embodiment, the icing condition of the electric tail fin can be detected based on an icing sensor, the electrical signal detected by the icing sensor can be obtained, and the accumulated ice value of the electric tail fin can be determined based on the electrical signal.
[0103] It should be noted that an icing sensor is a sensor that detects the thickness of ice on the surface of various objects. It converts icing signals into directly detectable electrical signals. Based on their detection mechanisms, icing sensors can be classified into optical, electrical, and mechanical types. The icing sensor in this embodiment specifically refers to an electrical icing sensor, which works by detecting the different electrical properties of ice, water, and air, and then converting that icing signal into a directly detectable electrical signal.
[0104] In some embodiments, the icing thickness of the electric tail fin can be determined based on the electrical signal detected by the icing sensor, and then the accumulated ice value of the electric tail fin can be determined based on the icing thickness. The greater the icing thickness, the greater the accumulated ice value. That is, the icing thickness and the accumulated ice value can be positively correlated.
[0105] For example, Figure 7 This is the fourth flowchart illustrating an ice-breaking method using an electric tail fin, as provided in the embodiments of this application. Figure 7 As shown, the method includes:
[0106] S701. Determine the ambient temperature of the vehicle.
[0107] S702. When it is determined that the ambient temperature is lower than the set temperature, the icing condition of the electric rear wing of the vehicle is detected based on the icing sensor, and the electrical signal detected by the icing sensor is obtained.
[0108] S703. Based on the electrical signal, determine the accumulated ice value of the electric tail fin, wherein the accumulated ice value is used to characterize the icing thickness level of the electric tail fin.
[0109] S704. Based on the accumulated ice value, determine the drive duty cycle and drive time of the target motor of the vehicle.
[0110] S705. Based on the drive duty cycle and the drive time, control the target motor to drive the electric tail fin to perform ice-breaking action.
[0111] For example, Figure 8 This is the fifth flowchart illustrating an electric tail fin ice-breaking method provided in this application embodiment, as shown below. Figure 8 As shown, the method includes:
[0112] S801: The temperature sensor is used to detect the ambient temperature of the vehicle in real time and upload the detected temperature data to the cloud platform. At the same time, the icing sensor is used to detect the icing of the vehicle's electric rear spoiler in real time based on the electrical properties of ice, water and air, and the accumulated ice value is determined based on the detected electrical signal and uploaded to the cloud platform.
[0113] S802. Upon receiving an indication from the cloud platform that the ambient temperature of the vehicle is less than 0°C, the vehicle body controller is activated.
[0114] S803. Determine the drive duty cycle and drive time by accumulating ice value and looking up the table.
[0115] S804: The target motor is continuously driven by the body controller to perform ice-breaking action based on the drive duty cycle.
[0116] S805. Determine if the drive time has been reached; if not, continue to step S804; if yes, proceed to step S806.
[0117] S806, Control the body controller to enter sleep mode.
[0118] It should be noted that conventional ice-breaking strategies only deploy the electric rear wing when the user needs it. However, if the electric rear wing is completely frozen solid at low temperatures for an extended period, it may fail to deploy effectively, resulting in ice-breaking failure. This embodiment of the application, however, considers the ambient temperature of the vehicle. When the ambient temperature is lower than a set temperature, it calculates the drive duty cycle and drive time based on the accumulated ice value. Then, based on the drive duty cycle and drive time, the vehicle controller automatically controls the target motor to drive the electric rear wing to perform the ice-breaking action. If the drive time has not been reached, the electric rear wing is continuously driven to perform the ice-breaking action until the drive is completed, at which point the vehicle controller enters a sleep state. This strategy effectively prevents the electric rear wing from freezing solid at low temperatures for an extended period, thus preventing ineffective ice-breaking failure.

[0121] The first determining module 910 is used to determine the ambient temperature of the vehicle.

[0123] The control module 930 is used to control the target motor to drive the electric rear wing of the vehicle to perform ice-breaking actions based on the drive duty cycle.
[0124] The electric rear wing ice-breaking device provided in this application embodiment can effectively prevent the electric rear wing from freezing solid in a low-temperature environment for a long time, thus preventing the electric rear wing from failing to effectively deploy and thus causing the electric rear wing to fail to break ice. This is achieved by automatically controlling the target motor to drive the electric rear wing to perform ice-breaking action based on a determined drive duty cycle when the ambient temperature of the vehicle is determined to be lower than a set temperature.
