Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an antifreeze control method, device, equipment and storage medium for an electric rear wing of a vehicle. Background Technology

[0002] With the continuous development of emerging car manufacturers, electric vehicles have risen rapidly, and they can now be seen on almost every street corner. Their unique designs and innovative technologies have won the favor of many users. For electric vehicles, electric rear spoilers add a lot of technological appeal, and their control is generally electric. The opening logic of an electric rear spoiler is as follows: when the car starts moving and reaches a certain speed (30km / h, a calibrable value), the electric rear spoiler automatically opens. However, with the use of electric rear spoilers, users have also reported some problems. For example, when the vehicle is parked in a parking area with low temperature and high humidity, the electric rear spoiler is prone to freezing and cannot be opened.

[0003] In existing technologies, some OEMs' electric vehicles are gradually being equipped with an automatic anti-freezing strategy for electric rear wings. This means that when the electric rear wing is detected as unable to open, the wing is opened by increasing the drive power or the number of drives.

[0004] However, increasing the driving power or the number of driving cycles to open the electric rear wing can easily damage the vehicle's electric rear wing and also lead to low opening efficiency of the electric rear wing in low temperature and high humidity environments. Summary of the Invention

[0005] This application provides a method, device, equipment, and storage medium for antifreeze control of an electric rear wing for vehicles, in order to solve the problem of low opening efficiency of electric rear wings under low temperature and high humidity environments.

[0006] In a first aspect, this application provides an antifreeze control method for a vehicle's electric rear spoiler, comprising:

[0007] The vehicle acquires an image of the surrounding environment while it is parked, and determines the parking environment of the vehicle based on the image. The parking environment includes both outdoor and indoor environments.

[0008] Under different parking environments, if the ambient temperature and / or ambient humidity conditions are met, the anti-freeze control mode for the electric rear wing will be activated. The anti-freeze control mode includes: a single heating control mode and a cyclic heating control mode.

[0009] According to the antifreeze control method, the body control module (BCM) is activated to control the rear wing heating module to heat the electric rear wing.

[0010] Secondly, this application provides an antifreeze control device for a vehicle's electric rear spoiler, comprising:

[0012] The processing module is used to activate the antifreeze control mode of the electric rear wing under different parking environments if the ambient temperature and / or ambient humidity conditions are met. The antifreeze control mode includes: a single heating control mode and a cyclic heating control mode.

[0013] The wake-up module is used to wake up the body control module (BCM) to control the rear wing heating module to heat the electric rear wing according to the anti-freeze control method.

[0014] Thirdly, this application provides an antifreeze control device for a vehicle's electric rear wing, comprising:

[0015] Processor, memory, communication interface;

[0016] The memory is used to store the executable instructions of the processor;

[0018] Fourthly, this application provides a readable storage medium, including: a computer program stored thereon, wherein the computer program, when executed by a processor, implements the antifreeze control method for the vehicle electric rear wing as described in the first aspect above.

[0019] The antifreeze control method, device, equipment, and storage medium for an electric rear wing provided in this application acquire environmental images of the vehicle's surroundings while it is parked, and determine the vehicle's parking environment based on these images. The parking environment includes both outdoor and indoor environments. Under different parking environments, if the ambient temperature and / or humidity conditions are met, an antifreeze control mode for the electric rear wing is activated. This antifreeze control mode includes a single-stage heating control mode and a cyclic heating control mode. Based on the antifreeze control mode, the Body Control Module (BCM) is activated to control the rear wing heating module to heat the electric rear wing. By activating different antifreeze control modes under different parking environments and different ambient temperature and / or humidity conditions to heat the vehicle's electric rear wing, the accuracy of the antifreeze control method for the vehicle's electric rear wing is improved, the probability of the electric rear wing freezing is reduced, and the opening efficiency of the electric rear wing in low-temperature and high-humidity environments is further improved.

[0032] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] In existing technologies, some OEMs are gradually incorporating automatic anti-freezing strategies for electric rear wings in their electric vehicles. This involves increasing the drive power or the number of drives to open the electric rear wing when it is detected that it cannot be opened. However, increasing the drive power or the number of drives to open the electric rear wing can easily damage the vehicle's electric rear wing and also leads to low opening efficiency of the electric rear wing in low temperature and high humidity environments.

[0035] This application acquires environmental images of the vehicle's surroundings while it is parked, determines the vehicle's parking environment based on these images, including both outdoor and indoor environments. Under different parking environments, if the ambient temperature and / or humidity conditions are met, an anti-freeze control mode for the electric rear spoiler is activated. This anti-freeze control mode includes a single-stage heating control mode and a cyclic heating control mode. Based on the anti-freeze control mode, the Body Control Module (BCM) is activated to control the rear spoiler heating module to heat the electric rear spoiler. By activating different anti-freeze control modes under different parking environments and different ambient temperature and / or humidity conditions to heat the vehicle's electric rear spoiler, the accuracy of the anti-freeze control method for the vehicle's electric rear spoiler is improved, the probability of the electric rear spoiler freezing is reduced, and the opening efficiency of the electric rear spoiler in low-temperature and high-humidity environments is further improved.

[0036] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0037] Figure 1 This is a flowchart illustrating the antifreeze control method for an electric rear wing of a vehicle provided in the first embodiment of this application.

[0038] like Figure 1 As shown, the antifreeze control method for the vehicle's electric rear wing in this embodiment may include the following steps:

[0039] Step S101: Acquire an image of the environment around the vehicle while it is parked, and determine the parking environment of the vehicle based on the image. The parking environment includes both outdoor and indoor environments.

[0040] Specifically, when the vehicle is parked, it can acquire images of the surrounding environment. Optionally, the methods for acquiring these images include, but are not limited to, acquiring them through cameras around the vehicle or by acquiring a high-definition map of the vehicle.

[0041] Specifically, after acquiring environmental images of the vehicle's surroundings, the vehicle's parking environment can be determined based on these images. The parking environment includes both outdoor and indoor environments.

[0042] Step S102: Under different parking environments, if the ambient temperature and / or ambient humidity conditions are met, the antifreeze control mode of the electric rear wing is activated. The antifreeze control mode includes: a single heating control mode and a cyclic heating control mode.

[0043] Specifically, under different parking environments described in step S101, if the corresponding ambient temperature and / or ambient humidity conditions are met, the corresponding antifreeze control mode of the electric tail wing is activated. The antifreeze control mode includes: a single heating control mode and a cyclic heating control mode.

[0044] Among them, the single-heating control method refers to the antifreeze control method of the vehicle's electric rear spoiler, which performs a single heating based on the heating temperature and heating duration when the vehicle is parked.

[0045] Among them, the cyclic heating control method refers to the antifreeze control method of the vehicle's electric rear spoiler, which cyclically heats the vehicle in a parked state according to the heating temperature, heating duration, and cycle interval of each cycle.

[0046] Optionally, the specific conditions for starting the vehicle to enter different electric rear spoiler antifreeze control methods under different parking environments, i.e., the specific conditions of ambient temperature and / or ambient humidity, can be set according to user needs, and this embodiment does not limit them.

[0047] Optionally, the conditions for the antifreeze control method described above for starting the vehicle to enter different electric rear wings under different parking environments include, but are not limited to, ambient temperature and / or ambient humidity conditions, and may also include other conditions that may cause the electric rear wings to freeze, such as water-soluble conditions. Optionally, the conditions for the antifreeze control method can be set according to user needs, and this embodiment does not limit them.

[0048] Step S103: According to the antifreeze control method, wake up the body controller (BCM) to control the rear wing heating module to heat the electric rear wing.

[0049] Specifically, the vehicle's Body Control Module (BCM) can be activated according to the anti-freeze control mode initiated in step S102, thereby controlling the rear wing heating module to heat the electric rear wing according to the anti-freeze control mode. Optionally, the vehicle's rear wing heating module includes, but is not limited to, a heating module integrated into the electric rear wing or an auxiliary heating module installed around the electric rear wing.

[0050] The antifreeze control method for the vehicle's electric rear wing provided in this embodiment acquires environmental images of the vehicle's surroundings while it is parked, determines the vehicle's parking environment based on these images, including both outdoor and indoor environments. Under different parking environments, if the ambient temperature and / or humidity conditions are met, the antifreeze control mode for the electric rear wing is activated. The antifreeze control mode includes a single-stage heating control mode and a cyclic heating control mode. Based on the antifreeze control mode, the Body Control Module (BCM) is activated to control the rear wing heating module to heat the electric rear wing. By activating different antifreeze control modes under different parking environments and different ambient temperature and / or humidity conditions to heat the vehicle's electric rear wing, the accuracy of the antifreeze control method for the vehicle's electric rear wing is improved, the probability of the vehicle's electric rear wing freezing is reduced, and the opening efficiency of the electric rear wing in low-temperature and high-humidity environments is further improved.

[0051] Figure 2 This second embodiment of the application provides a flowchart illustrating the anti-freeze control mode for activating the electric rear wing under different parking environments, provided that ambient temperature and / or humidity conditions are met. Figure 1 Based on the illustrated embodiment, this embodiment elaborates on the process of activating the antifreeze control mode of the electric tail wing under different parking environments if the ambient temperature and / or ambient humidity conditions are met.

[0052] like Figure 2 As shown, in different parking environments, if the ambient temperature and / or ambient humidity conditions are met, the activation of the anti-freeze control mode for the electric rear spoiler may include the following steps:

[0053] Step S201: In an outdoor environment, if the ambient temperature is lower than the ambient temperature threshold and the ambient humidity is higher than the ambient humidity threshold, then the circulating heating control mode of the electric tail wing is activated.

[0054] Specifically, according to step S101, if the vehicle is parked in an outdoor environment, and the ambient temperature is lower than the ambient temperature threshold and the ambient humidity is higher than the ambient humidity threshold (i.e., the vehicle is parked in an outdoor environment with low ambient temperature and high ambient humidity), then the circulating heating control mode for the electric rear spoiler is activated. The aforementioned ambient temperature and humidity thresholds can be preset according to user needs. For example, if the preset ambient temperature threshold is -2℃ and the preset ambient humidity is 70%, then in an outdoor environment, if the ambient temperature is lower than -2℃ and the ambient humidity is higher than 70%, the circulating heating control mode for the electric rear spoiler is activated.

[0055] Optionally, the vehicle's ambient temperature and humidity can be obtained from the vehicle's cloud information platform.

[0056] Step S202: In an outdoor environment, if the ambient temperature is greater than or equal to a preset ambient temperature threshold and / or the ambient humidity is less than or equal to a preset ambient humidity threshold, then the primary heating control mode of the electric tail wing is activated.

[0057] Specifically, according to step S101, if the vehicle is parked in an outdoor environment, and the ambient temperature is greater than or equal to a preset ambient temperature threshold, and / or the ambient humidity is less than or equal to a preset ambient humidity threshold, i.e., the vehicle is parked in an outdoor environment with high ambient temperature and / or low ambient humidity, then the primary heating control mode for the electric rear wing is activated. The ambient temperature threshold and ambient humidity threshold described in this step are equivalent to the preset ambient temperature threshold in step S201. For example, in an outdoor environment, if the ambient temperature is greater than or equal to -2℃, and / or the ambient humidity is less than or equal to 70%, then the primary heating control mode for the electric rear wing is activated.

[0058] Optionally, in outdoor environments, if the ambient temperature is greater than or equal to a preset second ambient temperature threshold, and / or the ambient humidity is less than or equal to a preset second ambient humidity threshold, the anti-freeze control mode for the electric rear spoiler will not be activated. That is, there is no need to perform anti-freeze control on the vehicle's electric rear spoiler. Here, the second ambient temperature threshold is greater than the second ambient temperature threshold, and the second ambient humidity threshold is less than the second ambient humidity threshold. For example, if the preset second ambient temperature is 2℃ and the preset second ambient humidity is 50%, in outdoor environments, if the ambient temperature is greater than or equal to 2℃ and / or the ambient humidity is less than or equal to 50%, the anti-freeze control mode for the electric rear spoiler will not be activated.

[0059] Step S203: In an indoor environment, if the ambient temperature is lower than the ambient temperature threshold and the ambient humidity is higher than the ambient humidity threshold, then the primary heating control mode of the electric tail wing is activated.

[0060] Specifically, according to step S101, if the vehicle is parked in an indoor environment, and the ambient temperature is lower than the ambient temperature threshold and the ambient humidity is higher than the ambient humidity threshold (i.e., the vehicle is parked in an indoor environment with low ambient temperature and high ambient humidity), then the primary heating control mode for the electric rear wing is activated. The ambient temperature threshold and ambient humidity threshold described in this step are equivalent to the preset ambient temperature threshold in step S201. For example, in an indoor environment, if the ambient temperature is lower than -2℃ and the ambient humidity is higher than 70%, then the primary heating control mode for the electric rear wing is activated.

[0061] Optionally, in an indoor environment, if the ambient temperature is greater than or equal to a preset ambient temperature threshold, and / or the ambient humidity is less than or equal to a preset ambient humidity threshold, i.e., when the vehicle is parked in an indoor environment with high ambient temperature and / or low ambient humidity, the anti-freeze control mode for the electric rear spoiler will not be activated. Here, the ambient temperature threshold and ambient humidity threshold described in this step are equivalent to the preset ambient temperature threshold in step S201. For example, in an indoor environment, if the ambient temperature is greater than or equal to -2℃ and the ambient humidity is less than or equal to 70%, the anti-freeze control mode for the electric rear spoiler will not be activated.

[0062] Figure 3 This is another schematic diagram illustrating an antifreeze control method for activating the electric rear wing under different parking environments, provided by an embodiment of this application, if the ambient temperature and / or ambient humidity conditions are met.

[0063] This embodiment provides a process for activating the antifreeze control mode of the electric rear spoiler under different parking environments, provided that the ambient temperature and / or ambient humidity conditions are met. Specifically, in outdoor environments, if the ambient temperature is lower than an ambient temperature threshold and the ambient humidity is higher than an ambient humidity threshold, a cyclic heating control mode for the electric rear spoiler is activated. If the ambient temperature is higher than or equal to a preset ambient temperature threshold and / or the ambient humidity is lower than or equal to a preset ambient humidity threshold, a primary heating control mode for the electric rear spoiler is activated. In indoor environments, if the ambient temperature is lower than an ambient temperature threshold and the ambient humidity is higher than an ambient humidity threshold, a primary heating control mode for the electric rear spoiler is activated. By setting different antifreeze control modes for the electric rear spoiler under different ambient temperature and humidity conditions in different parking environments, the accuracy of the antifreeze control method for the vehicle's electric rear spoiler is improved, the probability of the vehicle's electric rear spoiler freezing is reduced, and the opening efficiency of the electric rear spoiler in low-temperature and high-humidity environments is further improved.

[0064] Figure 4 This third embodiment of the application provides a flowchart illustrating the process of activating the Body Controller (BCM) to control the rear wing heating module to heat the electric rear wing when the antifreeze control method is a single-stage heating control method, according to the antifreeze control method. Figure 1 or Figure 2 Based on the illustrated embodiment, this embodiment elaborates on the process of waking up the body control module (BCM) to control the rear wing heating module to heat the electric rear wing when the antifreeze control mode is a single heating control mode.

[0065] like Figure 4 As shown, in this embodiment, when the antifreeze control mode is a single-heat control mode, according to the antifreeze control mode, waking up the body control module (BCM) to control the rear wing heating module to heat the electric rear wing may include the following steps:

[0066] Step S401: Detect whether the distance between the user and the vehicle is less than or equal to a preset distance threshold.

[0067] Specifically, as described in step S102, under different parking environments, if the ambient temperature and / or ambient humidity conditions are met, the antifreeze control mode for entering the electric rear wing is activated as a single heating control mode; or as described in step S202, in an outdoor environment, if the ambient temperature is greater than or equal to a preset ambient temperature threshold and / or the ambient humidity is less than or equal to a preset ambient humidity threshold, the single heating control mode for entering the electric rear wing is activated; or as described in step S203, in an indoor environment, if the ambient temperature is less than the ambient temperature threshold and the ambient humidity is greater than the ambient humidity threshold, the single heating control mode for entering the electric rear wing is activated. It is possible to detect whether the distance between the user and the vehicle is less than or equal to a preset distance threshold. Optionally, the method for detecting the distance between the user and the vehicle includes, but is not limited to, polling to find the user ID information through a Bluetooth module, a positioning UWB module, or other devices capable of querying the user ID. Specifically, the Bluetooth module or positioning module can be activated to detect whether the distance between the user and the vehicle is less than or equal to a preset distance threshold based on the user ID. If the Bluetooth module, the UWB positioning module, or other devices capable of querying the user ID find the user ID, then the distance between the user and the vehicle is detected to be less than or equal to a preset distance threshold. If the Bluetooth module, the UWB positioning module, or other devices capable of querying the user ID do not find the user ID, then the distance between the user and the vehicle is detected to be greater than the preset distance threshold. Optionally, the setting of the distance threshold is related to the method of detecting the distance between the user and the vehicle described above.

[0068] Step S402: If the distance between the user and the vehicle is less than or equal to the distance threshold, the Body Controller (BCM) is activated to control the rear wing heating module to heat the electric rear wing once.

[0069] Specifically, according to the detection in step S401, if the distance between the user and the vehicle is less than or equal to the distance threshold, the body control module (BCM) is activated to control the rear wing heating module to heat the electric rear wing once.

[0070] Optionally, as described in step S401, if the distance between the user and the vehicle is greater than the distance threshold, the body controller BCM is not woken up, and the detection described in step S401 continues until the distance between the user and the vehicle is less than or equal to the distance threshold. Then, the body controller BCM is woken up to control the rear wing heating module to heat the electric rear wing once.

[0071] Optionally, before activating the Body Control Module (BCM) to control the rear wing heating module to heat the electric rear wing, the heating temperature and duration for the first heating cycle can be determined based on the ambient temperature and humidity. Optionally, the vehicle's ambient temperature and humidity can be obtained from the vehicle's cloud information platform. Optionally, the heating temperature and duration can be obtained by calling a simulation model, such as a Simulink model, using a two-dimensional lookup table.

[0072] Optionally, after the Body Control Module (BCM) is activated to control the rear wing heating module to heat the electric rear wing once, the vehicle's ignition status can be detected. If the vehicle's ignition status is already activated, the one-time heating control mode of the electric rear wing is exited.

[0073] Optionally, after the Body Controller (BCM) is activated to control the rear wing heating module to heat the electric rear wing once, the vehicle's ignition status can be detected. If the vehicle's ignition status is not activated, the Body Controller (BCM) is controlled to enter a sleep state. At this time, the entire vehicle enters a low-power mode. When the distance between the vehicle and the controller is detected to be less than or equal to the distance threshold, the Body Controller (BCM) is activated to control the rear wing heating module to heat the electric rear wing once.

[0074] Figure 5 This is a schematic diagram illustrating another process for heating the electric rear wing by waking up the body controller (BCM) to control the rear wing heating module, according to the antifreeze control mode provided in this application embodiment when the antifreeze control mode is a single heating control mode.

[0075] This embodiment provides a process where, when the antifreeze control mode is a single-stage heating control mode, the Body Control Module (BCM) is activated to control the rear wing heating module to heat the electric rear wing according to the antifreeze control mode. This is achieved by detecting whether the distance between the user and the vehicle is less than or equal to a preset distance threshold. If the distance is less than or equal to the threshold, the BCM is activated to control the rear wing heating module to perform a single-stage heating of the electric rear wing. In the case of single-stage heating control, initiating the single-stage heating control of the electric rear wing by detecting the distance between the user and the vehicle improves the accuracy of the antifreeze control method for the vehicle's electric rear wing, reduces the probability of the electric rear wing freezing, and further improves the opening efficiency of the electric rear wing in low-temperature and high-humidity environments.

[0076] Figure 6 This fourth embodiment of the application provides a flowchart illustrating the process of activating the Body Controller (BCM) to control the rear wing heating module to heat the electric rear wing when the antifreeze control mode is a cyclic heating control mode, according to the antifreeze control mode. Figure 1 or Figure 2 Based on the illustrated embodiment, this embodiment elaborates on the process of waking up the body control module (BCM) to control the rear wing heating module to heat the electric rear wing when the antifreeze control mode is the cyclic heating control mode.

[0077] like Figure 6 As shown, in this embodiment, when the antifreeze control mode is the cyclic heating control mode, according to the antifreeze control mode, waking up the body control module (BCM) to control the rear wing heating module to heat the electric rear wing may include the following steps:

[0078] Step S601: Each time heating is performed, the heating temperature, heating duration, and cycle interval are determined based on the current ambient temperature and humidity of the vehicle.

[0079] Specifically, during each heating cycle, the heating temperature, heating duration, and cycle interval can be determined based on the vehicle's current ambient temperature and humidity. The cycle interval refers to the time interval between the current heating cycle and the next heating cycle. Optionally, the vehicle's ambient temperature and humidity can be obtained from the vehicle's cloud information platform. Alternatively, a simulation model, such as a Simulink model, can be used to obtain the heating temperature, heating duration, and cycle interval using a two-dimensional lookup table. For example, there could be a single-cycle heating temperature (Temp1), a single-cycle heating duration (HeatTimer1), and a single-cycle heating cycle interval (Timer1); and a second-cycle heating temperature (Temp2), a second-cycle heating duration (HeatTimer2), and a second-cycle heating cycle interval (Timer2), etc. Figure 7Here is an example graph showing the relationship between ambient temperature and humidity and the cycle time interval. Figure 8 This is an example graph showing the relationship between ambient temperature and humidity and heating time.

[0080] Step S602: Based on the heating temperature and heating time, wake up the body controller (BCM) to control the rear wing heating module to cyclically heat the electric rear wing.

[0081] Specifically, based on the heating temperature and heating duration determined in step S601, the body control module (BCM) can be activated to control the rear wing heating module, and the electric rear wing can be heated in one cycle according to the heating temperature and heating duration determined above.

[0082] Step S603: After each heating cycle, the body control module (BCM) enters a sleep state and enters the next heating cycle after the cycle interval time is reached.

[0083] Specifically, after each heating cycle, as described in step S602, the vehicle body controller (BCM) can be controlled to enter a sleep state. At this time, the vehicle enters a low-power mode, and after the cycle interval determined in step S601, it enters the next heating control. That is, based on the vehicle's current ambient temperature and humidity, the heating temperature, heating duration, and cycle interval for the next heating cycle are determined. Based on the heating temperature and duration of the next heating cycle, the BCM is awakened to control the rear wing heating module to perform the next heating cycle for the electric rear wing. After the next heating cycle, the BCM is controlled to enter a sleep state, and after the cycle interval is reached, it enters the next heating control cycle. For example:

[0084] Optionally, during the cyclic heating process described above, the vehicle's ignition status can be detected. Specifically, if the vehicle's ignition status is "ignited," the vehicle is controlled to stop cyclically heating the electric rear wing. That is, the cyclic heating control mode for the electric rear wing is exited. If the vehicle's ignition status is "not ignited," the vehicle is controlled to continue the cyclic heating process described above.

[0085] Figure 9 This is a schematic diagram illustrating another process for heating the electric rear wing by waking up the body controller (BCM) to control the rear wing heating module, according to the antifreeze control mode provided in this application embodiment when the antifreeze control mode is the cyclic heating control mode.

[0086] This embodiment provides a process where, when the antifreeze control mode is cyclic heating control, the vehicle body controller (BCM) is activated to control the rear wing heating module to heat the electric rear wing according to the antifreeze control mode. During each heating cycle, the heating temperature, heating duration, and cycle interval are determined based on the vehicle's current ambient temperature and humidity. Based on the heating temperature and duration, the BCM is activated to control the rear wing heating module to perform cyclic heating of the electric rear wing. After each heating cycle, the BCM enters a sleep state and enters the next heating control cycle after the cycle interval is reached. In the case of cyclic heating control, by determining the heating temperature, heating duration, and cycle interval for each cycle based on the vehicle's current ambient temperature and humidity, the accuracy of the antifreeze control method for the vehicle's electric rear wing is improved, the probability of the electric rear wing freezing is reduced, and the opening efficiency of the electric rear wing in low-temperature and high-humidity environments is further improved.

[0087] Figure 10 This is a schematic diagram of the antifreeze control device for an electric rear wing of a vehicle, provided in the fifth embodiment of this application.

[0088] like Figure 10 As shown, the antifreeze control device 100 for the vehicle electric rear wing in this embodiment includes a determination module 101, a processing module 102, and a wake-up module 103.

[0089] The determination module 101 is used to acquire environmental images around the vehicle when it is parked, and determine the parking environment of the vehicle based on the environmental images. The parking environment includes outdoor environment and indoor environment.

[0090] The processing module 102 is used to activate the antifreeze control mode of the electric rear wing under different parking environments if the ambient temperature and / or ambient humidity conditions are met. The antifreeze control mode includes: a single heating control mode and a cyclic heating control mode.

[0091] The wake-up module 103 is used to wake up the body controller (BCM) to control the rear wing heating module to heat the electric rear wing according to the anti-freeze control method.
