Description

Technical Field

[0001] The present disclosure relates to the technical field of grille control, and in particular to a grille anti-icing control method, device, equipment, storage medium and vehicle. Background Art

[0002] In order to reduce vehicle wind resistance and improve vehicle aesthetics, most models have added smart grille configurations. By intelligently adjusting the opening of the grille, the wind resistance of the entire vehicle can be reduced as much as possible, thereby reducing driving energy consumption while meeting the heat dissipation requirements of the vehicle's air-conditioning system and cooling system.

[0003] If the air conditioning system and the cooling system have no need for heat dissipation, the grille will remain in a closed state. If the ambient temperature is low and there is rain or snow, the closed grille will be at risk of freezing. At this time, if the grille is driven to move, the grille will enter the torque increase mode and break the ice by increasing the torque of the grille drive motor. When the grille freezes severely, the grille drive motor still cannot break the ice after increasing the torque to the maximum torque, and the grille will report a fault. At this time, the grille opening adjustment function will fail. Since the grille torque increase mode has a great impact on the durability of the grille motor, the grille control function will fail if the grille torque increase mode is used more frequently. Therefore, in order to reduce the number of times the grille torque increase mode is used, it is necessary to provide a method to prevent the grille from freezing.

[0004] In the prior art, the risk of grille icing is judged by the environmental conditions collected from the actual vehicle, so as to control the grille opening to prevent the grille from icing. However, the dimensions of the environmental conditions collected from the actual vehicle are relatively single, and usually only the ambient temperature can be sensed, but rain, snow and other weather factors cannot be sensed. The judgment based solely on the environmental conditions collected from the actual vehicle may be inaccurate, resulting in inaccurate control of the grille opening, which may cause the grille to be opened too frequently, affecting the warm-up of the engine and the heat storage effect of the electric drive system, or the grille to be opened too infrequently, resulting in the problem of grille icing.

[0062] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0063] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0064] The embodiments of the present disclosure provide a grille anti-icing control method, which is described below in conjunction with specific embodiments.

[0065] Figure 1 A flow chart of the grille anti-icing control method provided in the embodiment of the present disclosure. The method can be applied to a vehicle-mounted terminal, which can be a portable mobile device such as a smart phone, tablet computer, laptop computer, vehicle-mounted navigation device, smart sports equipment, etc.; it can also be a fixed device such as a personal computer, smart home appliance, etc. The method can be applied to the scenario of anti-icing control of the grille. The method solves the problem that the prior art only uses the environmental conditions collected from the actual vehicle for judgment and there is inaccurate judgment, which leads to inaccurate control of the grille opening. It is easy for the grille to be opened too frequently, affecting the warm-up of the engine and the heat storage effect of the electric drive system, or the grille is opened too infrequently, resulting in the problem of grille icing. The embodiment of the present disclosure obtains the current external meteorological data of the vehicle from the cloud meteorological data, and the external meteorological data includes weather conditions and temperature, determines the grille icing risk level that matches the weather conditions and the temperature, and determines the risk level of grille icing based on the wiper action state and the grille icing risk. The grille anti-icing level is determined, and the grille icing judgment is more accurate in combination with the current external meteorological data and the wiper operation status. The grille opening information is further calculated according to the grille icing risk level and the grille anti-icing level, and the grille of the vehicle is controlled to open with the opening cycle as the opening interval, the single opening time as the time of each opening, and the grille opening angle as the angle of each opening. The grille opening can be accurately and reasonably controlled, and the grille will not be opened too frequently or too infrequently, which can ensure the warm-up of the engine and the heat storage effect of the electric drive system, and prevent the grille from icing. It can be understood that the grille anti-icing control method provided in the embodiment of the present disclosure can also be applied in other scenarios.

[0066] Below Figure 1 The grid anti-icing control method shown in the figure is introduced, and the specific steps of the method are as follows:

[0067] S101. Acquire current external meteorological data of the vehicle from cloud meteorological data, where the external meteorological data includes weather conditions and temperature.

[0068] In this step, the vehicle terminal obtains the vehicle's current external meteorological data from the cloud meteorological data, and the external meteorological data includes weather conditions and temperature. For example, the vehicle terminal sends a request to the cloud server to obtain cloud data. The cloud server returns the cloud data to the vehicle terminal based on the request sent by the vehicle terminal to the cloud server to obtain cloud data. The vehicle terminal receives the cloud data and further obtains the vehicle's current external meteorological data from the cloud meteorological data.

[0069] In some embodiments, the external meteorological data may also include humidity, wind direction, pollution index, etc., which are not specifically limited here.

[0070] S102: Determine a grille icing risk level that matches the weather condition and the temperature.

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

[0072] S103: Determine a grille anti-icing level based on the wiper operating state and the grille icing risk level.

[0073] After determining the grille icing risk level, the vehicle-mounted terminal determines the grille anti-icing level based on the wiper operation state and the grille icing risk level. In some embodiments, the grille anti-icing level can be determined based on the wiper operation state and the corresponding relationship between the grille icing risk level and the grille anti-icing level. Alternatively, the grille anti-icing level is determined by a pre-trained machine learning model, the wiper operation state and the grille icing risk level are input into the pre-trained machine learning model, and the grille anti-icing level is determined by the pre-trained machine learning model. The present disclosure can also determine the grille anti-icing level by other means, which are not specifically limited here.

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

[0075] S104. Calculate grille opening information according to the grille icing risk level and the grille anti-icing level, wherein the grille opening information includes a grille opening angle, a single opening time, and an opening cycle.

[0076] In this step, the vehicle terminal calculates the grille opening information according to the grille icing risk level and the grille anti-icing level, and the grille opening information includes the grille opening angle, single opening time, and opening cycle. In some embodiments, the grille opening angle is the angle that the grille needs to be opened to prevent the grille from icing under the current driving conditions; the single opening time is the time that the grille needs to be opened once to prevent the grille from icing under the current driving conditions; the opening cycle is how long the grille needs to be opened once to prevent the grille from icing under the current driving conditions.

[0077] S105, controlling the grille of the vehicle to open with the opening cycle as the opening interval, the single opening time as the time of each opening, and the grille opening angle as the angle of each opening.

[0078] After calculating the grille opening information, the on-board terminal controls the opening of the grille according to the grille opening angle, the single opening time, and the opening cycle in the grille opening information. The grille opening can be accurately and reasonably controlled, and the grille will not be opened too frequently or too infrequently. The engine warm-up and heat storage effect of the electric drive system can be guaranteed, and the grille can be prevented from freezing.

[0079] The disclosed embodiment obtains the current external meteorological data of the vehicle from cloud meteorological data, wherein the external meteorological data includes weather conditions and temperature, determines a grille icing risk level that matches the weather conditions and the temperature, determines a grille anti-icing level based on the wiper operating state and the grille anti-icing level, and makes a more accurate grille icing judgment based on the current external meteorological data and the wiper operating state. Further, based on the grille icing risk level and the grille anti-icing level, the grille opening information is calculated, and the grille of the vehicle is controlled to open with the opening cycle as the opening interval, the single opening time as the time of each opening, and the grille opening angle as the angle of each opening. The grille opening can be accurately and reasonably controlled, and the grille will not be opened too frequently or too infrequently, thereby ensuring the warm-up of the engine and the heat storage effect of the electric drive system, and preventing the grille from icing.

[0080] Figure 2 A flow chart of a grille anti-icing control method provided by another embodiment of the present disclosure is shown in FIG. Figure 2 As shown, the method includes the following steps:

[0081] S201. Acquire current external meteorological data of the vehicle from cloud meteorological data, where the external meteorological data includes 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 meets the current external temperature, which is collected by the vehicle. The essence is to determine the validity of the cloud data. When the temperature in the external meteorological data meets the current external temperature, the temperature in the external meteorological data is valid, and the temperature in the external meteorological data is used to determine the grille icing risk level; when the temperature in the external meteorological data does not meet the current external temperature, the temperature in the external meteorological data is invalid, and the current external temperature is used to determine the grille icing risk level.

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

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

[0087] S2022, calculating an error of the temperature in the external meteorological data relative to the current external temperature;

[0088] S2023: If the error is within a preset error range, it is determined that the temperature in the external meteorological data is consistent with 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, determine a grille icing risk level that matches the weather condition 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-mounted 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 condition and the current external temperature.

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

[0093] S204: Determine a grille anti-icing level based on the wiper operating state and the grille icing risk level.

[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 grille icing risk level and the grille anti-icing level.

[0096] For example, the grille icing risk level is X, and the grille anti-icing level is Y, and the sum of the grille icing risk level and the grille anti-icing level is calculated to be (X+Y).

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

[0098] Optionally, the grille opening angle Q = (grill icing risk level X + grille anti-icing level Y) * grille opening correction factor Z, where the grille opening correction factor needs to be calibrated based on the grille actual vehicle icing performance. Optionally, the grille opening correction factor Z can be set to 4% or other values. The disclosed 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, calculating a second product of the sum of the two levels and the grille opening period correction factor, and determining the second product as the grille opening period.

[0100] Optionally, the grille opening cycle S = (grill icing risk level X + grille anti-icing level Y) * grille opening cycle correction factor R, where the grille opening cycle correction factor needs to be calibrated based on the actual vehicle icing performance of the grille. Optionally, the grille opening cycle correction factor R can be set to 20 minutes, or it can be set to other values. The embodiments of this disclosure are only used for explanation and are 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 cycle correction factor R is 20 minutes, then the calculated grille opening cycle S is 40 minutes.

[0101] S208: Determine the preset grille opening time as the single grille opening time.

[0102] In this step, the vehicle terminal obtains the 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 30s or other, and the user can set it by himself. The disclosed embodiment is only for explanation and not limitation.

[0103] S209, controlling the grille of the vehicle to open with the opening cycle as the opening interval, the single opening time as the time of each opening, and the grille opening angle 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 with the prior art, the disclosed embodiment obtains the current external meteorological data of the vehicle from cloud meteorological data, wherein the external meteorological data includes weather conditions and temperature, and determines whether the temperature in the external meteorological data matches the current external temperature. If the temperature in the external meteorological 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 state and the grille icing risk level, the grille anti-icing level is determined. Since the combination of the current external meteorological data and the wiper operation state can accurately determine the icing of the grille, the sum of the grille icing risk level and the grille anti-icing level is further calculated, and the first product of the sum of the two levels and the grille opening correction factor is calculated, and the first product is determined as the grille opening angle. The second product of the sum of the two levels and the grille opening period correction factor is calculated, and the second product is determined as the grille opening period. The preset grille opening time is determined as the time of a single grille opening, and then the grille of the vehicle is controlled to open with the opening period as the opening interval, the single opening time as the time of each opening, and the grille opening angle as the angle of each opening. The grille opening can be accurately and reasonably controlled, and the grille will not be opened too frequently or too infrequently, so that the warm-up of the engine and the heat storage effect of the electric drive system can be guaranteed, and the grille can be prevented from icing.

[0106] Figure 3 A flow chart of a grille anti-icing control method provided by another embodiment of the present disclosure is shown in FIG. Figure 3 As shown, the method includes the following steps:

[0107] S301. Obtain the current external meteorological data of the vehicle from cloud meteorological data, where the external meteorological data includes 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 a grille icing risk level that matches the weather condition 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, in some embodiments, S302 includes but is not limited to S3021, or S3022:

[0112] S3021. Based on a preset grille icing risk level table, look up the table to determine a grille icing risk level that matches the weather condition and the temperature.

[0113] Specifically, the grille icing risk level X that matches the weather condition and the temperature can be determined by looking up Table 1.

[0114]

[0115] It is understandable that the temperature can be a specific temperature value or a temperature range. The present disclosure uses specific temperature values ​​as examples. For example, the current weather is moderate snow, the temperature is -5°C, and the matching grille icing risk level is 1. For another example, the current weather is heavy snow, the temperature is 0°C, and the matching grille icing risk level is 2.

[0116] S3022: Input the weather condition and the temperature into a pre-trained grille icing risk level determination model, and output the grille icing risk level through the grille icing risk level determination model.

[0117] For example, there is a correspondence between the preset weather conditions and temperature and the preset grille icing risk level, and the correspondence between the preset weather conditions and temperature and the preset grille icing risk level is stored in advance in the vehicle terminal, or in the server, which is not limited in the disclosed embodiment. In this step, the vehicle terminal inputs the weather conditions and the temperature into the pre-trained grille icing risk level determination model, and the grille icing risk level is output through the grille icing risk level determination model.

[0118] S303: Determine a grille anti-icing level based on the wiper operating state and the grille icing risk level.

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

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

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

[0122] Specifically, the grille anti-icing level Y that matches the wiper operation state and the grille icing risk level may be determined by looking up Table 2.

[0123]

[0124] For example, if the wiper action state is fast action, the grille icing risk level X is 1, and the matching grille anti-icing level is 2. For another example, if the wiper action state is slow action, the grille icing risk level X is 2, and the matching grille anti-icing level is 1.

[0125] S3032: input the wiper operation state and the grille icing risk level into a 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 the preset wiper action state and the grille icing risk level and the preset grille anti-icing level, and the preset wiper action state and the grille icing risk level and the preset grille anti-icing level are stored in advance in the vehicle terminal, or in the server, which is not limited in the disclosed embodiment. In this step, the vehicle terminal inputs the wiper action state and the grille icing risk level into the pre-trained grille anti-icing level determination model, and outputs the grille anti-icing level through the grille anti-icing level determination model.

[0127] S304. Calculate grille opening information according to the grille icing risk level and the grille anti-icing level, wherein the grille opening information includes a grille opening angle, a single opening time, and an opening cycle.

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

[0129] S305, controlling the grille of the vehicle to open with the opening cycle as the opening interval, the single opening time as the time of each opening, and the grille opening angle as the angle of each opening.

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

[0131] S306: When it is detected that the vehicle is powered off, obtain the angle of the grille opening before the vehicle is powered off.

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

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

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

[0135] The disclosed embodiment obtains the current external meteorological data of the vehicle from cloud meteorological data, wherein the external meteorological data includes weather conditions and temperature, and determines the grille icing risk level that matches the weather conditions and the temperature. Further, based on the wiper action state and the grille icing risk level, the grille anti-icing level is determined, and according to the grille icing risk level and the grille anti-icing level, the grille opening information is calculated, wherein the grille opening information includes the grille opening angle, the time of a single opening, and the opening cycle, and then the grille of the vehicle is controlled to open with the opening cycle as the opening interval, the time of a single opening as the time of each opening, and the angle of the grille opening as the angle of each opening. When it is detected that the vehicle is powered off, the grille opening angle before the vehicle is powered off is obtained, and the preset grille opening time is controlled based on the grille opening angle before the vehicle is powered off. Compared with the prior art, since the grille icing judgment is more accurate in combination with the current external meteorological data and the wiper operation status, the grille opening information is further calculated according to the grille icing risk level and the grille anti-icing level, and then the vehicle's grille is controlled to open with the opening cycle as the opening interval, the single opening time as the time of each opening, and the grille opening angle as the angle of each opening. The grille opening can be accurately and reasonably controlled, and the grille will not be opened too frequently or too infrequently. The engine warm-up and heat storage effect of the electric drive system can be ensured, and the grille can be prevented from icing. When it is detected that the vehicle is powered off, the grille opening angle before the vehicle is powered off is obtained, and the grille opening preset time is controlled based on the grille opening angle before the vehicle is powered off, and the risk of grille icing caused by short-term parking can be avoided.
