Technical Field

[0001] This application relates to the field of vehicle technology, and to, but is not limited to, a method, apparatus, device, and storage medium for breaking ice on a charging compartment cover. Background Technology

[0002] With the continuous development of electric vehicles, more and more users are choosing electric vehicles as their means of transportation. For electric vehicles, the charging port cover is essential. However, in cold or rainy / snowy weather, the charging port cover of an electric vehicle may freeze and become impossible to open.

[0003] In related technologies, when a frozen charging case cover is detected and cannot be opened, a common approach is to increase the drive power to force the cover open. However, this method is ineffective for situations where the cover has been frozen for an extended period. Summary of the Invention

[0004] This application provides a method, apparatus, device, and storage medium for breaking ice on a charging compartment cover. The ice-breaking effect is good, and it can improve the ice-breaking efficiency of vehicle equipment while avoiding the waste of power consumption of vehicle equipment.

[0005] The technical solution of this application is implemented as follows:

[0006] In a first aspect, this application provides a method for breaking ice on a charging case cover, the method comprising:

[0007] When the vehicle equipment meets the opening conditions, the automatic ice-breaking function of the charging compartment cover of the vehicle equipment is activated.

[0008] In response to the automatic ice-breaking function of the charging compartment cover, the current automatic ice-breaking cycle of the charging compartment cover is determined based on the current environmental parameters of the vehicle equipment.

[0009] Based on the current automatic ice-breaking cycle, the charging compartment cover is periodically opened and closed to achieve automatic ice breaking.

[0010] Secondly, this application provides a charging compartment cover ice-breaking device, the device comprising:

[0011] An opening unit is used to activate the automatic ice-breaking function of the charging compartment cover of the vehicle equipment when the opening conditions are met.

[0012] A determining unit is configured to, in response to the automatic ice-breaking function of the charging compartment cover, determine the current automatic ice-breaking cycle of the charging compartment cover based on the current environmental parameters of the vehicle equipment.

[0013] An ice-breaking unit is used to periodically control the opening and closing of the charging compartment cover based on the current automatic ice-breaking cycle, so as to realize the automatic ice breaking of the charging compartment cover.

[0014] Thirdly, this application also provides a vehicle device, including: a memory and a processor, wherein the memory stores a computer program that can run on the processor, and the processor executes the program to implement the above-described method for breaking ice from the charging compartment cover.

[0015] Fourthly, this application also provides a storage medium storing a computer program that, when executed by a processor, implements the above-described method for breaking ice from the charging compartment cover.

[0016] The charging compartment cover ice-breaking method, apparatus, device, and storage medium provided in this application include at least: activating the automatic ice-breaking function of the charging compartment cover of the vehicle equipment when the vehicle equipment meets the opening conditions; determining the current automatic ice-breaking cycle of the charging compartment cover based on the current environmental parameters of the vehicle equipment in response to the automatic ice-breaking function of the charging compartment cover; and periodically controlling the charging compartment cover to open and close based on the current automatic ice-breaking cycle, so as to achieve automatic ice-breaking of the charging compartment cover.

[0017] In this application, when implementing the automatic ice-breaking function of the charging compartment cover, the automatic ice-breaking cycle of the charging compartment cover is linked to the environment in which the vehicle is located. By establishing a relationship between the environmental parameters of the vehicle and the automatic ice-breaking cycle, the current automatic ice-breaking cycle of the charging compartment cover can be determined based on the current environmental parameters of the vehicle. Furthermore, based on the current automatic ice-breaking cycle, the opening and closing of the charging compartment cover can be periodically controlled to achieve automatic ice breaking. It can be seen that this application's solution fully considers the impact of the vehicle's environment on the automatic ice-breaking function of the charging compartment cover. By establishing a relationship between the environmental parameters of the vehicle and the automatic ice-breaking cycle, the automatic ice-breaking cycle of the charging compartment cover can be adjusted accordingly to changes in the environmental parameters of the vehicle. This results in a better ice-breaking effect and improves the vehicle's ice-breaking efficiency while avoiding wasted power consumption. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of the application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0027] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0028] In the following description, the terms "first," "second," and "third" are used only to distinguish different objects and do not represent a specific order of objects, nor are they constituting a chronological order. It is understood that "first," "second," and "third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0030] This application provides a method, apparatus, device, and storage medium for breaking ice on the charging hatch cover. In practical applications, the method for breaking ice on the charging hatch cover can be implemented by a device for breaking ice on the charging hatch cover. The functional entities in the device can be implemented collaboratively by the hardware resources of the vehicle equipment, such as computing resources like processors and communication resources (such as those used to support various communication methods like fiber optic cables and cellular networks).

[0031] The following describes various embodiments of the charging compartment cover ice-breaking method, apparatus, device, and storage medium provided in this application.

[0032] Firstly, embodiments of this application provide a method for breaking ice from a charging compartment cover. This method is applied to a vehicle device (hereinafter referred to as the vehicle device) equipped with a charging compartment cover. The functions implemented by this method can be achieved by a processor in the vehicle device calling program code. Of course, the program code can be stored in a computer storage medium. Therefore, the vehicle device includes at least a processor and a storage medium.

[0033] The ice-breaking method for the charging compartment cover provided in the embodiments of this application will be described below.

[0034] Figure 1 This is a flowchart illustrating the ice-breaking method for the charging compartment cover according to an embodiment of this application. Figure 1 As shown, the process may include, but is not limited to, S101 to S103 described below.

[0035] In one possible implementation, the method is applied to vehicle equipment with a charging compartment cover, or to a controller within vehicle equipment with a charging compartment cover. For example, the method can be applied to an electric vehicle.

[0036] S101. When the opening conditions are met, the automatic ice-breaking function of the charging compartment cover of the vehicle equipment is activated.

[0037] The vehicle equipment can be any vehicle equipment; for example, it can be an electric vehicle.

[0038] The activation condition is used to determine whether to activate the automatic ice-breaking function of the vehicle's charging compartment cover.

[0039] This application does not limit the specific content of the activation conditions, and can be set according to the actual situation. For example, the activation conditions can be set to the temperature or humidity of the current environment of the vehicle equipment reaching a preset condition, or the location of the current environment of the vehicle equipment reaching a preset condition (such as outdoors).

[0040] This application does not limit the triggering method of the opening condition. For example, it can be automatically triggered by the vehicle equipment or manually triggered by the user.

[0041] Ice breaking refers to the removal or breaking of ice.

[0042] The charging compartment cover has an automatic ice-breaking function, which is used to automatically break the ice on the charging compartment cover. In this embodiment, the automatic ice-breaking function has two meanings: first, it refers to breaking the ice on the charging compartment cover; second, it refers to preventing the charging compartment cover from freezing.

[0043] Prior to this, the vehicle equipment has an automatic ice-breaking function for the charging compartment cover. For example, the corresponding S201 can be implemented as follows: the vehicle equipment determines whether the opening conditions for the automatic ice-breaking function for the charging compartment cover are met, and if the opening conditions are met, the automatic ice-breaking function for the charging compartment cover of the vehicle equipment is activated.

[0044] S102. In response to the automatic ice-breaking function of the charging compartment cover, the vehicle equipment determines the current automatic ice-breaking cycle of the charging compartment cover based on the current environmental parameters of the vehicle equipment.

[0045] The current environmental parameters of the vehicle equipment are used to help determine the current automatic de-icing cycle of the charging compartment cover. For example, the environmental parameters can be the temperature of the current environment in which the vehicle equipment is located, the environmental parameters can be the humidity of the current environment in which the vehicle equipment is located, or other environmental parameters that may cause the charging compartment cover to freeze. This application embodiment does not limit these parameters.

[0046] It should be noted that the current automatic ice-breaking cycle of the charging compartment cover will vary depending on the current environmental parameters of the vehicle's equipment.

[0047] The automatic ice-breaking cycle refers to the time (including the time for opening and closing the charging compartment cover, and the interval) during which the vehicle equipment periodically controls the charging compartment cover to perform an ice-breaking operation. For example, assuming the automatic ice-breaking cycle is 5 seconds, the execution time for opening and closing the charging compartment cover is 1 second, the interval is 4 seconds, and the vehicle equipment controls the charging compartment cover to perform an ice-breaking operation every 4 seconds.

[0048] For example, S102 can be implemented as follows: in response to the automatic ice-breaking function of the charging compartment cover, the vehicle equipment detects the temperature and / or humidity of the current environment in which the vehicle equipment is located, and calculates the automatic ice-breaking cycle for the charging compartment cover to perform one ice-breaking operation based on the temperature and / or humidity of the current environment in which the vehicle equipment is located.

[0049] S103. Based on the current automatic ice-breaking cycle, the vehicle equipment periodically controls the opening and closing of the charging compartment cover to achieve automatic ice breaking of the charging compartment cover.

[0050] This application does not limit the specific method by which the vehicle equipment controls the opening and closing of the charging compartment cover. For example, the vehicle equipment can control the charging compartment cover to perform opening and closing operations by sending opening and closing commands to the charging compartment cover through the Body Control Module (BCM).

[0051] For example, S103 can be implemented as follows: at the start of the current automatic ice-breaking cycle, the vehicle equipment sends an open and close command to the charging compartment cover via the BCM. After receiving the open and close command, the charging compartment cover performs an open and close operation. After an interval of one current automatic ice-breaking cycle, the vehicle equipment sends an open and close command to the charging compartment cover via the BCM again. After receiving the open and close command, the charging compartment cover performs an open and close operation again. After another interval of one current automatic ice-breaking cycle, the vehicle equipment continues to send an open and close command to the charging compartment cover via the BCM. After receiving the open and close command, the charging compartment cover performs an open and close operation again. This cycle repeats, thereby achieving periodic control of the charging compartment cover to open and close.

[0052] The charging compartment cover ice-breaking method, apparatus, device, and storage medium provided in this application include at least: activating the automatic ice-breaking function of the charging compartment cover of the vehicle equipment when the vehicle equipment meets the opening conditions; determining the current automatic ice-breaking cycle of the charging compartment cover based on the current environmental parameters of the vehicle equipment in response to the automatic ice-breaking function of the charging compartment cover; and periodically controlling the charging compartment cover to open and close based on the current automatic ice-breaking cycle, so as to achieve automatic ice-breaking of the charging compartment cover.

[0053] In this application, when implementing the automatic ice-breaking function of the charging compartment cover, the automatic ice-breaking cycle of the charging compartment cover is linked to the environment in which the vehicle is located. By establishing a relationship between the environmental parameters of the vehicle and the automatic ice-breaking cycle, the current automatic ice-breaking cycle of the charging compartment cover can be determined based on the current environmental parameters of the vehicle. Furthermore, based on the current automatic ice-breaking cycle, the opening and closing of the charging compartment cover can be periodically controlled to achieve automatic ice breaking. It can be seen that this application's solution fully considers the impact of the vehicle's environment on the automatic ice-breaking function of the charging compartment cover. By establishing a relationship between the environmental parameters of the vehicle and the automatic ice-breaking cycle, the automatic ice-breaking cycle of the charging compartment cover can be adjusted accordingly to changes in the environmental parameters of the vehicle. This results in a better ice-breaking effect and improves the vehicle's ice-breaking efficiency while avoiding wasted power consumption.

[0054] The following describes the process in S102 where the vehicle equipment determines the current automatic ice-breaking cycle of the charging compartment cover based on the current environmental parameters of the vehicle equipment.

[0055] This process may include, but is not limited to, Method 1 and Method 2 described below.

[0056] Method 1: The vehicle equipment determines the current automatic de-icing cycle of the charging compartment cover based on the target temperature and the first relationship, or based on the target humidity and the second relationship;

[0057] Method 2: The vehicle equipment determines the current automatic de-icing cycle of the charging compartment cover based on the target humidity, the target humidity, and a third relationship.

[0058] The following explains the process by which the vehicle equipment in Method 1 determines the current automatic de-icing cycle of the charging compartment cover based on the target temperature and the first relationship, or based on the target humidity and the second relationship.

[0059] refer to Figure 2 The method may include, but is not limited to, the following S201 to S203.

[0060] S201. The vehicle equipment detects the target temperature or target humidity of the current environment in which the vehicle equipment is located.

[0061] Pre-installed temperature or humidity sensors are mounted on the exterior of the vehicle equipment. The target temperature of the current environment in which the vehicle equipment is located can be obtained through the temperature sensor, and the target humidity of the current environment in which the vehicle equipment is located can be obtained through the humidity sensor. For example, the temperature or humidity sensor can be installed on the exterior of the vehicle equipment near the charging compartment cover to more accurately detect the temperature or humidity of the environment in which the charging compartment cover is located.

[0062] This application does not limit the number of temperature or humidity sensors installed. For example, one temperature sensor or one humidity sensor, or multiple temperature sensors or multiple humidity sensors, can be installed on the outside of the vehicle equipment. When multiple temperature sensors are installed on the outside of the vehicle equipment, the average or median of the multiple temperature values ​​can be used as the target temperature of the current environment of the vehicle equipment. When multiple humidity sensors are installed on the outside of the vehicle equipment, the average or median of the multiple humidity values ​​can be used as the target humidity of the current environment of the vehicle equipment.

[0063] This application does not limit the specific method for detecting the target temperature or target humidity of the current environment of the vehicle equipment. For example, it can be a real-time detection method.

[0064] S202, Vehicle equipment obtains the first or second relationship.

[0065] The first relationship is used to characterize the relationship between temperature and automatic ice breaking cycle.

[0066] For example, the first relationship can be pre-configured and stored in the memory of the vehicle equipment.

[0067] The first relationships stored in vehicle equipment from different regions and manufacturers may be exactly the same, or they may differ. For example, climate differences in different regions may lead to differences in the relationship between temperature or humidity and automatic de-icing cycles, so the first relationships stored in vehicle equipment from different regions may also differ; different manufacturers may use different methods to obtain the first relationships, so the first relationships stored in vehicle equipment from different manufacturers may also differ.

[0068] The second relationship is used to characterize the relationship between humidity and automatic de-icing cycle.

[0069] For example, the second relationship can be pre-configured and stored in the memory of the vehicle equipment.

[0070] The second relationship stored in vehicle equipment from different regions and manufacturers may be exactly the same, or there may be some differences.

[0071] The embodiments of this application do not specifically limit the representation of the first and second relations, and can be configured according to actual conditions. For example, the first relation can be in the form of a curve, a function, or a table, etc.

[0072] S202 can be implemented as follows: the vehicle equipment retrieves a first relation or a second relation from the memory. Specifically, if the current environmental parameter of the vehicle equipment is the temperature of the current environment in which the vehicle equipment is located, the first relation is retrieved; if the current environmental parameter of the vehicle equipment is the humidity of the current environment in which the vehicle equipment is located, the second relation is retrieved.

[0073] S203. The vehicle equipment determines the current automatic de-icing cycle of the charging compartment cover based on the target temperature and the first relationship; or, it determines the current automatic de-icing cycle of the charging compartment cover based on the target humidity and the second relationship.

[0074] Knowing the target temperature, the temperature, and the automatic ice-breaking cycle, the current automatic ice-breaking cycle of the charging compartment cover can be calculated. For example, since the first relationship characterizes the relationship between temperature and the automatic ice-breaking cycle, the automatic ice-breaking cycle corresponding to the target temperature can be found in or calculated using the first relationship, and used as the current automatic ice-breaking cycle.

[0075] Similarly, given the target humidity and the second relationship between humidity and automatic de-icing cycle, the current automatic de-icing cycle of the charging compartment cover can be calculated. For example, since the second relationship characterizes the relationship between humidity and automatic de-icing cycle, the automatic de-icing cycle corresponding to the target humidity can be found in or calculated using the second relationship, and used as the current automatic de-icing cycle.

[0076] The following explains the process of determining the current automatic de-icing cycle of the charging compartment cover based on the target humidity, the target humidity, and the third relationship in Method 2.

[0077] refer to Figure 3 The process may include, but is not limited to, S301 to S303 described below.

[0078] S301. The vehicle equipment detects the target temperature and target humidity of the current environment in which the vehicle equipment is located.

[0079] For methods for vehicle equipment to detect the target temperature and target humidity of the current environment, please refer to the specific description of the vehicle equipment detecting the target temperature or target humidity of the current environment in Method 1 above.

[0080] S302, Vehicle equipment obtains third-party relationships.

[0081] The third relationship is used to characterize the relationship between temperature, humidity and automatic ice-breaking cycle.

[0082] For example, the third relationship can be pre-configured and stored in the vehicle's memory.

[0083] The third-party relations stored in vehicle equipment from different regions and manufacturers may be exactly the same, or they may have some differences. For example, climate differences in different regions lead to differences in the relationship between temperature, humidity and automatic de-icing cycles, so the third-party relations stored in vehicle equipment from different regions will also have some differences; different manufacturers may use different methods to obtain the third-party relations, so the third-party relations stored in vehicle equipment from different manufacturers will also have some differences.

[0084] The embodiments of this application do not specifically limit the form of the third relationship, and can be configured according to the actual situation. For example, the third relationship can be in the form of a three-dimensional curve, a function, or a table, etc.

[0085] S302 can be implemented as follows: when the current environmental parameters of the vehicle equipment include the temperature and humidity of the current environment of the vehicle equipment, the vehicle equipment retrieves the third relationship from the memory.

[0086] S303. The vehicle equipment determines the current automatic de-icing cycle of the charging compartment cover based on the target temperature, the target humidity, and the third relationship.

[0087] Knowing the target temperature, target humidity, and a third relationship between temperature, humidity, and automatic de-icing cycle, the current automatic de-icing cycle of the charging compartment cover can be calculated. For example, since the third relationship characterizes the relationship between temperature, humidity, and automatic de-icing cycle, the automatic de-icing cycle corresponding to the target temperature and target humidity can be found in or calculated using the third relationship, and used as the current automatic de-icing cycle.

[0088] In one possible implementation, for the first relationship, temperature and automatic ice-breaking cycle are positively correlated; for the second relationship, humidity and automatic ice-breaking cycle are negatively correlated; for the third relationship, in the first dimension, temperature and automatic ice-breaking cycle are positively correlated; and in the second dimension, humidity and automatic ice-breaking cycle are negatively correlated.

[0089] It should be noted that the positive and negative correlations mentioned here can be linear or non-linear.

[0090] The following describes the process by which the vehicle equipment in S103 periodically controls the opening and closing of the charging compartment cover based on the current automatic ice-breaking cycle.

[0091] refer to Figure 4 The method may include, but is not limited to, S401 to S404 described below.

[0092] S401, The vehicle equipment controls the charging compartment cover to perform an opening and closing operation once.

[0093] This application does not limit the specific method by which the vehicle equipment controls the charging compartment cover to perform an opening and closing operation. For example, the vehicle equipment can control the charging compartment cover to perform an opening and closing operation by sending an opening and closing command from the BCM to the charging compartment cover.

[0094] In one possible implementation, after the charging compartment cover completes an opening and closing operation, if the vehicle equipment is in operation, the vehicle equipment is controlled to enter a sleep state to avoid wasting power.

[0095] S402, The vehicle equipment starts the first timer.

[0096] The duration of the first timer is determined based on the current automatic ice-breaking cycle.

[0097] It should be noted that there is no strict execution order between the above steps S401 and S402. They can be executed simultaneously or in a specific order. This application does not limit this.

[0098] The process of determining the timing duration of the first timer based on the current automatic ice-breaking cycle is explained below.

[0099] This process may include, but is not limited to, the following methods A and B.

[0100] Method A: The vehicle equipment determines the current automatic ice-breaking cycle as the timing duration of the first timer.

[0101] Method B: The vehicle equipment subtracts the time taken for the vehicle equipment to control the charging compartment cover to perform one opening and closing operation from the current automatic ice-breaking cycle, and determines the timing duration of the first timer as the difference.

[0102] For method A, for example, when steps S401 and S402 are executed simultaneously, method A can be used to determine the current automatic ice-breaking cycle as the timing duration of the first timer. For example, if the current automatic ice-breaking cycle is 6 seconds, then the timing duration of the first timer is determined to be 6 seconds.

[0103] For method B, for example, if steps S401 and S402 are executed in sequence, method B can be used to determine the duration of the first timer by subtracting the time taken for the vehicle equipment to control the charging compartment cover to perform one opening and closing operation from the current automatic ice-breaking cycle. For example, if the current automatic ice-breaking cycle is 10 seconds and the time taken for the vehicle equipment to control the charging compartment cover to perform one opening and closing operation is 4 seconds, then the duration of the first timer is determined to be 6 seconds.

[0104] S403. When the first timer reaches the specified time duration, the vehicle equipment controls the charging compartment cover to perform an opening and closing operation once.

[0105] The timing method of the first timer is not limited in this application embodiment; it can be a forward timing method or a countdown timing method.

[0106] In one possible implementation, after the first timer reaches its set duration, if the vehicle equipment is in a sleep state, the vehicle equipment is controlled to enter the working state to control the charging compartment cover to perform an opening and closing operation.

[0107] S404. The vehicle equipment re-determines the current new automatic ice-breaking cycle and, based on the current new automatic ice-breaking cycle, re-determines the new timing duration of the first timer; re-executes the activation of the first timer, and when the timing of the first timer reaches the new timing duration, controls the charging compartment cover to perform an opening and closing operation once, until the vehicle equipment no longer meets the opening conditions.

[0108] Re-determining the current automatic ice-breaking cycle refers to re-detecting and determining the current automatic ice-breaking cycle based on the current environmental parameters of the vehicle equipment.

[0109] For example, assuming the current automatic ice-breaking cycle is 10 seconds, the time it takes for the vehicle equipment to control the charging compartment cover to perform one opening and closing operation is 4 seconds, and the vehicle equipment uses method B above to determine the timing duration of the first timer, then the vehicle equipment determines the timing duration of the first timer to be 6 seconds. When the first timer reaches 6 seconds, the vehicle equipment controls the charging compartment cover to perform one opening and closing operation. Then, the vehicle equipment re-determines the current new automatic ice-breaking cycle to be 15 seconds, re-determines the new timing duration of the first timer to be 11 seconds, and restarts the first timer. When the first timer reaches the new timing duration of 11 seconds, it controls the charging compartment cover to perform one opening and closing operation. This cycle repeats until the vehicle equipment no longer meets the opening conditions.

[0110] The activation conditions in S101 will be explained below.

[0111] The activation conditions include at least the following: the temperature of the current environment in which the vehicle equipment is located is less than or equal to a first preset temperature; and the humidity of the current environment in which the vehicle equipment is located is greater than or equal to a first preset humidity.

[0112] The first preset temperature is used to help determine whether to activate the automatic ice-breaking function of the vehicle's charging compartment cover.

[0113] The specific value of the first preset temperature is not limited in the embodiments of this application. For example, the first preset temperature can be -2 degrees Celsius (°C).

[0114] The first preset humidity is used to help determine whether to activate the automatic de-icing function of the vehicle's charging compartment cover.

[0115] The specific value of the first preset humidity is not limited in the embodiments of this application. For example, the first preset humidity can be a relative value of 70%.

[0116] This application does not limit the specific content of the enabling conditions, which can be set according to actual conditions. For example, the enabling conditions may include:

[0117] The temperature of the current environment in which the vehicle equipment is located is less than or equal to a first preset temperature;

[0118] Furthermore, the humidity of the current environment in which the vehicle equipment is located is greater than or equal to the first preset humidity;

[0119] Furthermore, the vehicle equipment is in a parked state;

[0120] Furthermore, the vehicle equipment is located in an outdoor environment;

[0121] Furthermore, the power supply status of the vehicle equipment is in the off state.

[0122] For example, the temperature and humidity of the current environment of the vehicle equipment can be obtained by temperature and humidity sensors installed on the outside of the vehicle equipment; the vehicle equipment can be parked by detecting the gear information of the vehicle equipment; the vehicle equipment can be outdoors by acquiring environmental images of the environment in which the vehicle equipment is located by acquiring environmental images and detecting and recognizing the acquired environmental images; and the vehicle equipment can be powered off by detecting the power status of the vehicle equipment.

[0123] The ice-breaking method for the charging compartment provided in this application embodiment may also include the closing process of the charging compartment cover.

[0124] Specifically, the process may include: turning off the automatic de-icing function of the charging compartment cover when the temperature of the current environment of the vehicle equipment is greater than a first preset temperature; or turning off the automatic de-icing function of the charging compartment cover when the humidity of the current environment of the vehicle equipment is less than a first preset humidity.

[0125] This application does not limit the conditions for disabling the automatic ice-breaking function of the charging compartment cover in this embodiment of the vehicle equipment; these conditions can be set according to actual circumstances. For example, the vehicle equipment can also disable the automatic ice-breaking function of the charging compartment cover under any of the following conditions:

[0126] The temperature of the current environment in which the vehicle equipment is located is greater than the first preset temperature;

[0127] Alternatively, the humidity of the environment in which the vehicle equipment is currently located is less than the first preset humidity;

[0128] Alternatively, the vehicle equipment may be in an active state.

[0129] Alternatively, the vehicle equipment may be located in an indoor environment;

[0130] Alternatively, the power status of the vehicle equipment is "powered on".

[0131] For example, the temperature or humidity of the vehicle's current environment can be obtained by using a temperature sensor or humidity sensor installed on the outside of the vehicle; the vehicle's gear position information can be detected to determine whether the vehicle is running; the vehicle's image processing module can capture images of the environment in which the vehicle is located, and the captured images can be detected and identified to determine whether the vehicle is in an indoor environment; the vehicle's power status can be detected to determine whether the vehicle is powered on.

[0132] The following example illustrates the ice-breaking method for the charging compartment cover provided in this application.

[0133] With the continuous development of emerging car manufacturers, electric vehicles have risen rapidly, becoming a common sight on streets and alleys. Their unique designs and innovative technologies have won the favor of many users. For electric vehicles, the charging port cover is essential, and its control is electrically powered. However, with the use of electric charging port covers, users have reported some problems. For example, in winter, when the car is parked outdoors, the charging port cover easily freezes and becomes impossible to open. Statistics show that when the outdoor temperature ranges from -10℃ to -2℃, the charging port cover is prone to ice accumulation, and the lower the temperature, the faster the freezing. Similarly, when the relative humidity is greater than 70%, the charging port cover is also prone to ice accumulation, and the higher the relative humidity, the higher the frequency of freezing.

[0134] Some OEMs have gradually adopted charging case cover ice-breaking strategies, which involve increasing drive power to open the charging case cover when it is detected that it cannot be opened. This strategy is effective when the charging case cover is frozen for a short period of time, but it becomes less effective when the freezing time is long. This application proposes a charging case cover ice-breaking method to solve the problem of the charging case cover being unable to open under low temperature and high humidity conditions.

[0135] When a car is parked outdoors in conditions of high humidity and low temperature, the car will automatically activate the automatic de-icing function of the charging compartment cover. The automatic de-icing cycle varies with the ambient temperature and relative humidity, thus effectively reducing the risk of the charging compartment cover freezing in conditions of low temperature and high relative humidity.

[0136] The automatic de-icing method of this application employs the following approach: An image processor determines whether the vehicle is currently in an indoor or outdoor environment. When the vehicle is parked in a low-temperature (temperature less than -2℃) and high-humidity (relative humidity greater than 70%) outdoor environment, the automatic de-icing function of the charging port cover is activated, and the frequency of automatic de-icing (automatic de-icing cycle) is adjusted according to changes in external temperature and humidity. When the vehicle is parked indoors, the charging port cover is unlikely to freeze, and the automatic de-icing function is not activated. Similarly, when the vehicle is parked in a non-low-temperature environment, the charging port cover is unlikely to freeze, and the automatic de-icing function is not activated. Furthermore, when the vehicle is parked in a low-humidity environment, the charging port cover is unlikely to freeze, and the automatic de-icing function is not activated. This method effectively prevents the charging port cover from freezing and becoming unopenable due to low temperature and high humidity.

[0137] Below, for reference Figure 5 The content shown illustrates the process of the automatic ice-breaking method for the charging compartment cover of this application. Specifically, it may include the following steps:

[0138] 1. The vehicle's image processor module determines whether the car is parked indoors or outdoors based on the current environment. When the car is parked indoors, the vehicle automatically de-ices the charging compartment cover. When the car is parked outdoors, and the vehicle cloud information platform reports that the current ambient temperature is greater than -2℃ or the relative humidity is less than 70%, the vehicle automatically de-ices the charging compartment cover. When the car is parked outdoors, and the vehicle cloud information platform reports that the current ambient temperature is less than -2℃ and the relative humidity is greater than 70%, the vehicle cloud information platform sends a command through the vehicle network terminal (Telematics Box, TBOX) to wake up the body control module (BCM).

[0139] 2. The Body Control Controller (BCM) first issues commands to open and close the charging compartment cover, then obtains the current ambient temperature (Temp1, equivalent to the temperature of the environment where the aforementioned vehicle equipment is currently located) and relative humidity (RH1, equivalent to the humidity of the environment where the aforementioned vehicle equipment is currently located) through the TBOX, and then calculates the current automatic de-icing cycle of the charging compartment cover (Timer1, equivalent to the timing duration of the first timer mentioned above). After that, the entire vehicle enters a sleep state, and at this time, Timer1 is started.

[0140] 3. After Timer1 expires, the vehicle body controller (BCM) is reawakened. The BCM first sends commands to open and close the charging compartment cover, then obtains the current ambient temperature (Temp2) and relative humidity (RH2) through the TBOX, and calculates the current automatic de-icing cycle (Timer2) of the charging compartment cover. After that, the vehicle enters a sleep state and Timer2 is started.

[0141] 4. Repeat steps 2 and 3 until the vehicle's local power supply is turned ON, then exit the timer and stop the automatic ice-breaking function of the charging compartment cover.

[0142] In short, the ice-breaking process of the charging compartment cover of the vehicle equipment in this application can be referenced. Figure 5 The description mainly includes S501~S521.

[0164] The relationship between the automatic ice-breaking cycle (Timer) of the charging compartment cover and the ambient temperature (Temp) and relative humidity (RH) in this application is as follows: Figure 6 As shown.

[0165] It should be noted that the automatic ice-breaking cycle of the charging compartment cover in this application can be automatically adjusted according to changes in ambient temperature and humidity. The relationship between the automatic ice-breaking cycle of the charging compartment cover and temperature and humidity in this application can be constructed using a Simulink model. The automatic ice-breaking cycle under different ambient temperatures and humidity levels can be obtained through real-vehicle calibration. In the Simulink model, the automatic ice-breaking cycle of the charging compartment cover is obtained through a two-dimensional lookup table, as shown in the two-dimensional lookup table model. Figure 7 As shown.

[0166] refer to Figure 7 The data shown can be input into a Simulink model to obtain the corresponding automatic de-icing cycle. For example, inputting the temperature u1 and humidity u2 of the current environment in which the vehicle is located into the Simulink model will yield the current automatic de-icing cycle y1 of the vehicle.

[0167] The ice-breaking method for the charging compartment cover provided in this embodiment has the following effects:

[0168] In this application, when implementing the automatic ice-breaking function of the charging compartment cover, the automatic ice-breaking cycle of the charging compartment cover is linked to the environment in which the vehicle is located. By establishing a relationship between the environmental parameters of the vehicle and the automatic ice-breaking cycle, the current automatic ice-breaking cycle of the charging compartment cover can be determined based on the current environmental parameters of the vehicle. Furthermore, based on the current automatic ice-breaking cycle, the opening and closing of the charging compartment cover can be periodically controlled to achieve automatic ice breaking. It can be seen that this application's solution fully considers the impact of the vehicle's environment on the automatic ice-breaking function of the charging compartment cover. By establishing a relationship between the environmental parameters of the vehicle and the automatic ice-breaking cycle, the automatic ice-breaking cycle of the charging compartment cover can be adjusted accordingly to changes in the environmental parameters of the vehicle. This results in a better ice-breaking effect and improves the vehicle's ice-breaking efficiency while avoiding wasted power consumption.
