Description

Technical Field

[0001] This disclosure relates to the field of grille control technology, and in particular to a grille anti-icing control method, device, equipment, storage medium, and vehicle. Background Technology

[0002] To reduce vehicle drag and improve aesthetics, most models have added intelligent grille configurations. By intelligently adjusting the grille opening, the overall vehicle drag is reduced as much as possible while meeting the heat dissipation needs of the vehicle's air conditioning and cooling systems, thus reducing driving energy consumption.

[0003] If the air conditioning and cooling systems have no heat dissipation requirements, the grille will remain closed. However, in low ambient temperatures and rainy / snowy weather, the closed grille may freeze. If the grille is activated, it will enter a torque-increasing mode, increasing the torque of the grille drive motor to break the ice. If the grille is severely iced, and the drive motor fails to break the ice even at maximum torque, the grille will report a fault, and the grille opening adjustment function will fail. Since the torque-increasing mode significantly impacts the durability of the grille motor, frequent use of this mode will cause the grille control function to malfunction. Therefore, to reduce the frequency of using the torque-increasing mode, a method to prevent grille icing is needed.

[0004] In existing technologies, the risk of grille icing is assessed by collecting environmental conditions from actual vehicles, thereby controlling the grille opening to prevent icing. However, the environmental conditions collected from actual vehicles are relatively limited in scope, typically only sensing ambient temperature and not weather factors such as rain or snow. Relying solely on these environmental conditions can lead to inaccurate assessments, resulting in inaccurate control of grille opening. This can easily lead to the grille opening being too frequent, affecting engine warm-up and the heat storage effect of the electric drive system, or the grille opening being too infrequent, causing grille icing.

[0062] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0063] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0064] This disclosure provides a method for preventing grid icing, which will be described in detail below with reference to specific embodiments.

[0065] Figure 1 This is a flowchart illustrating a grille anti-icing control method provided in an embodiment of this disclosure. This method can be applied to in-vehicle terminals, which can be portable mobile devices such as smartphones, tablets, laptops, in-vehicle navigation devices, and smart sports equipment; or fixed devices such as personal computers and smart home appliances. This method can be applied to scenarios involving grille anti-icing control. It addresses the problem in existing technologies where judging environmental conditions solely based on data collected from the actual vehicle is inaccurate, leading to inaccurate control of grille opening. This can result in grille opening too frequently, affecting engine warm-up and the heat storage effect of the electric drive system, or grille opening too infrequently, causing grille icing. This embodiment of the disclosure obtains the vehicle's current external meteorological data from cloud-based meteorological data, including weather conditions and temperature, determines a grille icing risk level matching the weather conditions and temperature, and then applies this risk level based on the wiper operation status and grille icing risk. The method determines the grille's anti-icing level by combining current external weather data and wiper operation status for a relatively accurate assessment of grille icing. Further, based on the grille icing risk level and the grille anti-icing level, grille opening information is calculated. This allows for precise and reasonable control of the vehicle's grille opening, using the opening period as the opening interval, the duration of each single opening as the opening time, and the grille opening angle as the opening angle for each opening. This ensures accurate and reasonable control of the grille opening, preventing either excessively frequent or insufficient grille opening, thus guaranteeing engine warm-up and the heat storage effect of the electric drive system, and preventing grille icing. It is understood that the grille anti-icing control method provided in this embodiment can also be applied to other scenarios.

[0066] The following is about Figure 1 The method for preventing icing of the grille shown is described below, and the specific steps of this method are as follows:

[0067] S101. Obtain the vehicle's current external weather data from cloud-based weather data, including weather conditions and temperature.

[0068] In this step, the vehicle-mounted terminal obtains the vehicle's current external weather data from cloud-based meteorological data, including weather conditions and temperature. For example, the vehicle-mounted terminal sends a request to the cloud server to retrieve cloud data. Based on the request, the cloud server returns the cloud data to the vehicle-mounted terminal. Upon receiving the cloud data, the vehicle-mounted terminal further retrieves the vehicle's current external weather data from the cloud-based meteorological data.

[0069] In some embodiments, the external meteorological data may also include humidity, wind direction, pollution index, etc., without specific limitations.

[0070] S102. Determine the grid icing risk level that matches the weather conditions and the temperature.

[0071] After acquiring current external meteorological data, the vehicle-mounted terminal determines a grille icing risk level that matches the weather conditions and temperature in the current external meteorological data. For example, the grille icing risk level can be determined based on the correspondence between the weather conditions, the temperature, and the grille icing risk level. Alternatively, the grille icing risk level can be determined using a pre-trained machine learning model. The weather conditions and the temperature are input into the pre-trained machine learning model, and the grille icing risk level is determined through the pre-trained machine learning model. This disclosure can also determine the grille icing risk level in other ways, which are not specifically limited here.

[0072] S103. Determine the anti-icing level of the windshield based on the wiper operation status and the risk level of grille icing.

[0073] After determining the grille icing risk level, the vehicle terminal determines the grille anti-icing level based on the wiper operation status and the grille icing risk level. In some embodiments, the grille anti-icing level can be determined according to the correspondence between the wiper operation status and the grille icing risk level and the grille anti-icing level. Alternatively, the grille anti-icing level can be determined using a pre-trained machine learning model. The wiper operation status and the grille icing risk level are input into the pre-trained machine learning model, and the pre-trained machine learning model determines the grille anti-icing level. This disclosure may also determine the grille anti-icing level in other ways, which are not specifically limited here.

[0074] In some embodiments, the wiper operation state includes at least one of the following: fast operation, medium speed operation, slow operation, and stop.

[0075] S104. Calculate the grid opening information based on the grid icing risk level and the grid anti-icing level. The grid opening information includes the grid opening angle, the time of a single opening, and the opening cycle.

[0076] In this step, the vehicle terminal calculates grille opening information based on the grille icing risk level and the grille anti-icing level. The grille opening information includes the grille opening angle, the duration of a single opening, and the opening cycle. In some embodiments, the grille opening angle is the angle the grille needs to open to prevent icing under current driving conditions; the duration of a single opening is the time the grille needs to open to prevent icing under current driving conditions; and the opening cycle is the interval between openings required under current driving conditions to prevent icing.

[0077] S105. Control the vehicle's grille to open at intervals with the opening period as the opening interval, the time of each single opening as the time of each opening, and the angle of the grille opening as the angle of each opening.

[0078] After calculating the grille opening information, the vehicle terminal controls the grille opening based on the grille opening angle, the time of a single opening, and the opening period in the grille opening information. This allows for accurate and reasonable control of the grille opening, preventing the grille from opening too frequently or too infrequently. This ensures the engine warm-up and the heat storage effect of the electric drive system, and also prevents the grille from icing.

[0079] This embodiment of the disclosure obtains the vehicle's current external meteorological data from cloud-based meteorological data, including weather conditions and temperature. It determines a grille icing risk level matching the weather conditions and temperature, and determines the grille anti-icing level based on the wiper operation status and the grille icing risk level. Combining the current external meteorological data and wiper operation status provides a more accurate assessment of grille icing. Furthermore, based on the grille icing risk level and the grille anti-icing level, it calculates grille opening information, thereby controlling the vehicle's grille to open at intervals defined by the opening period, the duration of each single opening, and the angle of each grille opening. This allows for accurate and reasonable control of the grille opening, preventing either excessively frequent or insufficient grille opening, ensuring engine warm-up and heat storage in the electric drive system, and preventing grille icing.

[0080] Figure 2 A flowchart of a grid anti-icing control method provided in another embodiment of this disclosure is shown below. Figure 2 As shown, the method includes the following steps:

[0081] S201. Obtain the vehicle's current external weather data from cloud-based weather data, including weather conditions and temperature.

[0082] Specifically, the implementation process and principle of S201 and S101 are the same, and will not be repeated here.

[0083] S202. Determine whether the temperature in the external meteorological data matches the current external temperature.

[0084] In this step, the vehicle terminal determines whether the temperature in the external meteorological data matches the current external temperature, which is collected by the vehicle. Essentially, this checks the validity of the cloud-based data. If the temperature in the external meteorological data matches the current external temperature, the temperature in the external meteorological data is valid, and it will be used to determine the grille icing risk level. If the temperature in the external meteorological data does not match the current external temperature, the temperature in the external meteorological data is invalid, and the current external temperature will be used to determine the grille icing risk level.

[0085] In some embodiments, S202 includes, but is not limited to, S2021, S2022, and S2023:

[0086] S2021. Obtain the current external temperature collected by the vehicle temperature sensor;

[0087] S2022. Calculate the error of the temperature in the external meteorological data relative to the current external temperature;

[0088] S2023. If the error is within the preset error range, it is determined that the temperature in the external meteorological data matches the current external temperature.

[0089] In some embodiments, if the error is not within a preset error range, it is determined that the temperature in the external meteorological data does not conform to the current external temperature.

[0090] S203. If the temperature in the external meteorological data does not match the current external temperature, then determine the grid icing risk level that matches the weather conditions and the current external temperature.

[0091] If it is determined that the temperature in the external meteorological data does not match the current external temperature, the vehicle terminal uses the current external temperature to determine the grille icing risk level, and further determines the grille icing risk level that matches the weather conditions and the current external temperature.

[0092] In some embodiments, if the temperature in the external meteorological data matches the current external temperature, a grid icing risk level matching the weather conditions and the temperature is determined.

[0093] S204. Determine the anti-icing level of the windshield based on the wiper operation status and the risk level of grille icing.

[0094] Specifically, the implementation process and principle of S204 and S103 are the same, and will not be repeated here.

[0095] S205. Calculate the sum of the icing risk level and the icing prevention level of the grid.

[0096] For example, if the icing risk level of the grid is X and the icing prevention level of the grid is Y, the sum of the icing risk level and the icing prevention level of the grid is calculated to be (X+Y).

[0097] S206. Calculate the first product of the sum of the two levels and the grid opening correction factor, and determine the first product as the angle of the grid opening.

[0098] Optionally, the grille opening angle Q = (Grilled icing risk level X + Grilled anti-icing level Y) * Grille opening correction factor Z, where the grille opening correction factor needs to be calibrated based on the actual icing performance of the grille on a real vehicle. Optionally, the grille opening correction factor Z can be set to 4%, or it can be set to other values. This embodiment is only for explanation and is not limited. For example, if the grille icing risk level X is 1, the grille anti-icing level Y is 1, and the grille opening correction factor Z is 4%, then the calculated grille opening angle Q is 8%.

[0099] S207. Calculate the second product of the sum of the two levels and the grid opening period correction factor, and determine the second product as the grid opening period.

[0100] Optionally, the grille opening period S = (Grilled icing risk level X + Grilled anti-icing level Y) * Grille opening period correction factor R, where the grille opening period correction factor needs to be calibrated based on the actual icing performance of the grille on a real vehicle. Optionally, the grille opening period correction factor R can be set to 20 minutes, or it can be set to other values. This embodiment is only for explanation and is not limited. For example, if the grille icing risk level X is 1, the grille anti-icing level Y is 1, and the grille opening period correction factor R is 20 minutes, then the calculated grille opening period S is 40 minutes.

[0101] S208. Set the preset grille opening time as the time for a single grille opening.

[0102] In this step, the vehicle terminal obtains a preset grille opening time and determines the preset grille opening time as the time for a single grille opening. Optionally, the preset grille opening time can be 30 seconds, or it can be set to other values. Users can set it themselves. This embodiment is only for explanation and is not intended to limit the scope.

[0103] S209. Control the vehicle's grille to open at intervals with the opening period as the opening interval, the time of each single opening as the time of each opening, and the angle of the grille opening as the angle of each opening.

[0104] Specifically, the implementation process and principle of S209 and S105 are the same, and will not be repeated here.

[0105] Compared to existing technologies, this disclosure embodiment obtains the vehicle's current external weather data from cloud-based meteorological data, including weather conditions and temperature, and determines whether the temperature in the external weather data matches the current external temperature. If the temperature in the external weather data does not match the current external temperature, a grille icing risk level matching the weather conditions and the current external temperature is determined. Based on the wiper operation status and the grille icing risk level, the grille anti-icing level is determined. Since combining current external weather data and wiper operation status provides a relatively accurate assessment of grille icing, the sum of the grille icing risk level and the grille anti-icing level is further calculated. The sum of these two levels is then multiplied by a first grille opening correction factor, and this first product is used to determine the grille opening angle. A second product of the sum of these two levels and a grille opening period correction factor is then calculated, and this second product is used to determine the grille opening period. A preset grille opening time is then set as the time for a single grille opening. This allows for precise and reasonable control of the grille opening, preventing either excessively frequent or insufficient grille opening. This ensures proper engine warm-up and heat storage in the electric drive system, while also preventing grille icing.

[0106] Figure 3 A flowchart of a grid anti-icing control method provided in another embodiment of this disclosure is shown below. Figure 3 As shown, the method includes the following steps:

[0107] S301. Obtain the vehicle's current external weather data from cloud-based weather data, including weather conditions and temperature.

[0108] Specifically, the implementation process and principle of S301 and S101 are the same, and will not be repeated here.

[0109] S302. Determine the grid icing risk level that matches the weather conditions and the temperature.

[0110] Specifically, the implementation process and principle of S302 and S102 are the same, and will not be repeated here.

[0111] In some embodiments, S302 includes, but is not limited to, S3021 or S3022:

[0112] S3021. Based on the preset grid icing risk level table, determine the grid icing risk level that matches the weather conditions and the temperature by looking up the table.

[0113] Specifically, the grid icing risk level X, which matches the weather conditions and temperature, can be determined by referring to Table 1.

[0114]

[0115] It is understood that temperature can be a specific temperature value or a temperature range. This disclosure uses specific temperature values ​​as examples. For instance, if the current weather is moderate snow and the temperature is -5℃, the corresponding grid icing risk level is 1. Or, for example, if the current weather is heavy snow and the temperature is 0℃, the corresponding grid icing risk level is 2.

[0116] S3022. Input the weather conditions and the temperature into the pre-trained grid icing risk level determination model, and output the grid icing risk level through the grid icing risk level determination model.

[0117] For example, there is a correspondence between preset weather conditions and temperatures and preset grille icing risk levels. This correspondence can be stored in the vehicle terminal or on a server; this embodiment is not limited to this. In this step, the vehicle terminal inputs the weather conditions and temperature into a pre-trained grille icing risk level determination model, and the model outputs the grille icing risk level.

[0118] S303. Based on the wiper operation status and the risk level of grille icing, determine the anti-icing level of the grille.

[0119] Specifically, the implementation process and principle of S303 and S103 are the same, and will not be repeated here.

[0120] In some embodiments, S303 includes, but is not limited to, S3031 or S3032:

[0121] S3031. Based on a preset grille anti-icing level table, determine the grille anti-icing level that matches the wiper operation state and the grille icing risk level by referring to the table.

[0122] Specifically, the anti-icing level Y of the windshield can be determined by referring to Table 2, which matches the windshield wiper operation status and the windshield icing risk level.

[0123]

[0124] For example, if the wipers are operating at high speed, the grille icing risk level X is 1, and the matched grille anti-icing level is 2. As another example, if the wipers are operating at low speed, the grille icing risk level X is 2, and the matched grille anti-icing level is 1.

[0125] S3032. Input the wiper operation status and the grille icing risk level into the pre-trained grille anti-icing level determination model, and output the grille anti-icing level through the grille anti-icing level determination model.

[0126] For example, there is a correspondence between preset wiper operation states and grille icing risk levels and preset grille anti-icing levels. This correspondence can be stored in the vehicle terminal or on a server; this embodiment is not limited to this. In this step, the vehicle terminal inputs the wiper operation states and the grille icing risk level into a pre-trained grille anti-icing level determination model, and the model outputs the grille anti-icing level.

[0127] S304. Based on the icing risk level and the icing prevention level of the grid, calculate the grid opening information, which includes the grid opening angle, the time of a single opening, and the opening cycle.

[0128] Specifically, the implementation process and principle of S304 and S104 are the same, and will not be repeated here.

[0129] S305. Control the vehicle's grille to open at intervals based on the opening period, the time of each single opening, and the angle of the grille opening.

[0130] Specifically, the implementation process and principle of S305 and S105 are the same, and will not be repeated here.

[0131] S306. When the vehicle power is detected to be off, obtain the angle of the grille opening before the vehicle power is off.

[0132] When the vehicle terminal detects that the vehicle is powered off, it obtains the angle of the grille opening before the vehicle was powered off.

[0133] S307. Control the grille opening for a preset time based on the angle of the grille opening before the vehicle is powered off.

[0134] Furthermore, controlling the preset time of the grille opening based on the angle of the grille opening before the vehicle is powered off can avoid the risk of grille icing caused by short-term parking. For example, if the angle of the grille opening before the vehicle is powered off is 8%, the on-board terminal controls the preset time of the grille opening based on the 8% angle. The preset time can be 5 minutes, which can be set by the user and is not limited here.

[0135] This embodiment of the disclosure obtains the vehicle's current external meteorological data from cloud-based meteorological data, including weather conditions and temperature, and determines a grille icing risk level matching the weather conditions and temperature. Further, based on the wiper operation status and the grille icing risk level, a grille anti-icing level is determined. Based on the grille icing risk level and the grille anti-icing level, grille opening information is calculated, including the grille opening angle, the duration of a single opening, and the opening cycle. This information is then used to control the vehicle's grille to open at intervals defined by the opening cycle, with each opening duration defined by the duration of a single opening, and with each opening angle defined by the grille opening angle. When a vehicle power failure is detected, the grille opening angle before power failure is obtained, and the grille opening time is controlled based on this angle for a preset duration. Compared to existing technologies, this method more accurately judges grille icing by combining current external meteorological data and wiper operation status. Furthermore, based on the grille icing risk level and anti-icing level, it calculates grille opening information and controls the vehicle's grille opening with the opening period as the opening interval, the single opening time as the opening duration, and the grille opening angle as the opening angle. This allows for accurate and reasonable control of the grille opening, preventing either excessively frequent or insufficient grille opening. It ensures proper engine warm-up and heat storage in the electric drive system, and prevents grille icing. When the vehicle is powered off, it obtains the grille opening angle before power-off and controls the preset grille opening time based on this angle, thus avoiding the risk of grille icing caused by short-term parking.

Figure 4 As shown, the grille anti-icing control device 40 includes: an acquisition module 41, a first determination module 42, a second determination module 43, a calculation module 44, and a control module 45. The acquisition module 41 acquires the vehicle's current external weather data from cloud-based meteorological data, including weather conditions and temperature. The first determination module 42 determines a grille icing risk level matching the weather conditions and temperature. The second determination module 43 determines the grille anti-icing level based on the wiper operation status and the grille icing risk level.
