[0033] In order to solve the above problems, the embodiments of the present disclosure provide a method, device, server, medium and vehicle for predicting a fuse event. Figure 1 The method for predicting a fuse event provided by an embodiment of the present disclosure is described in detail.
[0034] Figure 1 A flow chart of a method for predicting a fuse event provided in an embodiment of the present disclosure is shown.
[0035] In the embodiment of the present disclosure, the fuse event prediction method may be executed by a server. Specifically, the server may include but is not limited to a cloud server or a cloud server cluster.
[0036] like Figure 1 As shown, the fuse event prediction method may include the following steps.
[0037] S110: Acquire original data of the target vehicle within a target time period.
[0038] In the disclosed embodiment, the server may obtain raw data of the target vehicle within a target time period.
[0039] Optionally, the target vehicle may be a moving vehicle.
[0040] Optionally, the target time period may be a pre-set time period. For example, the target time period may be set in units of seconds, minutes, days, months, years, etc., such as within 10 seconds, within a day, within a month, etc., which is not limited here.
[0041] Optionally, the raw data may be various data of the target vehicle, for example, the raw data may include battery current data, battery temperature data, fuse temperature data, fuse internal resistance data, battery life data, vehicle mileage data, etc., which are not limited here.
[0042] Specifically, when the target vehicle is driving, the vehicle motion domain controller (XCU) can collect the original data of the target vehicle and upload it to the server's database for storage via the HU. The server can search and obtain the original data of the target vehicle within the target time period in the database.
[0043] S120, performing feature extraction processing on the original data to obtain target feature data.
[0044] In the disclosed embodiment, after obtaining the original data, the server may perform feature extraction processing on the original data to obtain target feature data.
[0045] Optionally, the feature extraction process may be a process for extracting required feature data from the data. For example, the feature extraction process may be a process for extracting time-based target feature data from the data.
[0046] Optionally, the target feature data may be data with specific features. For example, the target feature data may include short-time scale feature data, long-time scale feature data, and full-life cycle statistical feature data, etc., which are not limited here.
[0047] Specifically, after obtaining the original data, the server may perform feature extraction processing on the original data, that is, extract required feature data from the original data to obtain target feature data.
[0048] Optionally, after obtaining the raw data, the server may preprocess the raw data, such as performing deduplication processing, denoising processing, etc., and then perform feature extraction processing on the preprocessed raw data.
[0049] S130. Input the target feature data into the trained fuse prediction model to obtain the fuse prediction probability output by the fuse prediction model.
[0050] In the disclosed embodiment, after obtaining the target feature data, the server may input the target feature data into a trained fuse prediction model to obtain the fuse prediction probability output by the fuse prediction model.
[0051] Optionally, the trained fuse prediction model may be a pre-trained machine learning model for performing fuse prediction processing. For example, the trained fuse prediction model may be a binary classification model.
[0052] Optionally, the blown fuse prediction process may be a process of predicting the probability of a fuse blowing.
[0053] Optionally, the predicted probability of a blown fuse may be used to characterize the probability of a blown fuse. For example, the predicted probability of a blown fuse may be expressed in the form of a percentage, a fraction, etc., such as 60%, 3 / 4, etc., which is not limited here.
[0054] Specifically, after obtaining the target feature data, the server can input the target feature data into a trained fuse prediction model. The trained fuse prediction model can perform fuse prediction processing on the input target feature data, thereby outputting a corresponding fuse prediction probability, and the server can obtain the fuse prediction probability.
[0055] S140: If the predicted probability of the fuse blowing meets the preset probability condition, it is predicted that the fuse of the target vehicle will blow.
[0056] In the disclosed embodiment, after obtaining the predicted probability of the fuse being blown, if the predicted probability of the fuse being blown satisfies a preset probability condition, the server predicts that a fuse blown event will occur in the target vehicle's fuse.
[0057] Optionally, the preset probability condition may be a predefined probability condition.
[0058] Optionally, the fuse can be used for overload protection. For example, when the current rises to a certain height and temperature, the fuse will melt and cut off the current, thus protecting the safe operation of the circuit.
[0059] Specifically, after obtaining the predicted probability of the fuse, the server can judge the predicted probability of the fuse, and if the predicted probability of the fuse meets the preset probability condition, it can be determined that the fuse of the target vehicle is about to have a fuse blown event. The specific judgment method is described below.
[0060] Therefore, in the disclosed embodiment, the original data of the target vehicle within the target time period can be obtained, and the original data can be subjected to feature extraction processing to obtain target feature data, and then the target feature data is input into the trained fuse prediction model to obtain the fuse prediction probability output by the fuse prediction model. If the fuse prediction probability meets the preset probability condition, it is predicted that the fuse of the target vehicle will have a fuse blown event. Therefore, the original data can be subjected to feature extraction processing to obtain the target feature data, and the target feature data can be subjected to fuse prediction processing to obtain the fuse prediction probability. Finally, when the fuse prediction probability meets the preset probability condition, it is predicted that the fuse of the target vehicle will have a fuse blown event, thereby accurately predicting the fuse blown event and ensuring the safety of the vehicle while driving.
[0061] In some embodiments, the target characteristic data may include short time scale characteristic data.
[0062] Optionally, the short-time scale characteristic data may be characteristic data obtained with a short time as the scale.
[0063] Optionally, S120 may specifically include: based on a preset current threshold, counting the number of overcurrent times of the original data within a first preset time; adding a current weighting coefficient to the overcurrent times information to obtain short-time scale characteristic data.
[0064] In the embodiment of the present disclosure, the server may count the number of overcurrent times of the original data within a first preset time based on a preset current threshold.
[0065] Optionally, the preset current threshold may be a pre-set current threshold. For example, the preset current threshold is set according to different fuse models, such as the preset current threshold may be 5A, 6A, etc., which is not limited here.
[0066] Optionally, the first preset time may be a preset time, for example, the first preset time may be 1 day, 2 days, etc., which is not limited here.
[0067] Optionally, the overcurrent count information may be used to indicate the number of times the current exceeds a preset current threshold.
[0068] Specifically, after obtaining the original data, the server can count the number of times the current exceeds the preset current threshold within a first preset time in the original data, such as 1 day, to obtain overcurrent information, and set a time step, such as counting the overcurrent information within a week.
[0069] Furthermore, the server may add a current weighting coefficient to the overcurrent number information to obtain short-time scale characteristic data.
[0070] Optionally, the current weighting coefficient may be a coefficient used to characterize the weight of the current.
[0071] Specifically, the server can add a current weighting coefficient to the overcurrent count information to obtain short-time scale characteristic data. Since the current data changes frequently and the sampling frequency is generally in units of 10ms or 100ms, adding a current weighting coefficient to the current that changes dramatically can improve the effectiveness of the overcurrent count information.
[0072] In other embodiments, the target characteristic data may also include long time scale characteristic data.
[0073] Optionally, the long-time scale characteristic data may be characteristic data obtained with a long time as a scale.
[0074] Optionally, S120 may specifically include: counting the heat generation calculated value of the original data within the second preset time; based on a preset temperature threshold, counting the heat generation calculated value and the step overtemperature information within the second preset time to obtain long-time scale characteristic data.
[0075] In the embodiment of the present disclosure, the server may count the sum of the heat generation calculation values of the original data within the second preset time.
[0076] Optionally, the second preset time may be a pre-set time, such as one month, one year, etc., which is not limited here.
[0077] Optionally, the sum of the heat generation calculation values may be the sum of the heat generation calculation values of the fuse within the second preset time.
[0078] Specifically, since the main reason for the blowing of the fuse is the excessive heat generation of the device, and the effect of excessive heat generation has a cumulative effect, the server can count the sum of the heat generation calculation values of the original data within the second preset time. For example, the server can count the sum of the heat generation calculation values of multiple fuses within one month. The heat generation calculation value can be the square of the current within 10s * power-on time * theoretical internal resistance * life coefficient, so as to obtain the corresponding heat generation calculation value.
[0079] Furthermore, after obtaining the heat generation calculation value and, based on a preset temperature threshold, the server can statistically calculate the heat generation calculation value and the step over-temperature information within a second preset time to obtain long-time scale characteristic data.
[0080] Optionally, the preset temperature threshold may be a pre-set temperature threshold, for example, the preset temperature threshold may be 80°, 90°, etc., which is not limited here.
[0081] Optionally, the step over-temperature information may be information used to indicate that the temperature exceeds a preset temperature threshold.
[0082] Specifically, the server can set preset temperature thresholds for different stages, compare the obtained heat production calculation value with the preset temperature threshold, and count the corresponding step over-temperature information within the second preset time. For example, if the heat production calculation value is greater than the preset temperature threshold of the first stage, the corresponding first-level step over-temperature information is obtained, and all step over-temperature information within one month is counted to obtain long-time scale characteristic data.
[0083] In some other embodiments, the target characteristic data may also include full life cycle statistical characteristic data.
[0084] Optionally, the full life cycle statistical feature data may be statistical feature data over the full life cycle.
[0085] Optionally, the full life cycle statistical characteristic data may include battery life information and vehicle mileage information.
[0086] Optionally, the battery life information may be information used to characterize the battery life of the target vehicle. The vehicle mileage information may be information used to characterize the mileage of the target vehicle.
[0087] Specifically, the server can obtain the statistical characteristic data of the target vehicle's entire life cycle in the database, including battery life information and vehicle mileage information. The battery life information and vehicle mileage information can be collected using the vehicle motion domain controller (XCU) of the target vehicle and uploaded to the server's database via the HU for storage.
[0088] Optionally, before inputting the target feature data into the trained fuse prediction model, the fuse event prediction method may also include: obtaining historical original data, and performing feature extraction processing on the historical original data to obtain historical feature data; labeling the historical feature data to obtain a training feature data set and a verification feature data set; based on the training feature data set and the verification feature data set, performing model training and model verification on the fuse prediction model to obtain a trained fuse prediction model.
[0089] In the disclosed embodiment, the server may obtain the historical raw data of the target vehicle, and perform feature extraction processing on the historical raw data to obtain historical feature data.
[0090] Optionally, the historical raw data may be various data of the target vehicle in the historical time. For example, the historical raw data may include battery current data, battery temperature data, fuse temperature data, fuse internal resistance data, battery life data, vehicle mileage data, etc., which are not limited here.
[0091] Optionally, the historical feature data may be historical data with specific features. For example, the historical feature data may include historical short-time scale feature data, historical long-time scale feature data, and historical full-life cycle statistical feature data, etc., which are not limited here.
[0092] Specifically, when the target vehicle is driving, the vehicle motion domain controller (XCU) can collect the historical raw data of the target vehicle and upload it to the server's database for storage via the HU. The server can search and obtain the historical raw data in the database, and then perform feature extraction processing on the historical raw data to obtain the corresponding historical feature data.
[0093] Furthermore, the server may label the historical feature data to obtain a training feature data set and a verification feature data set.
[0094] Optionally, the label marking may be marking different data with different labels.
[0095] Optionally, the training feature data set may be a feature data set for model training.
[0096] Optionally, the verification feature dataset may be a feature dataset for performing model verification.
[0097] Specifically, the server can label the historical feature data to obtain a training feature data set and a verification feature data set. For example, in order to achieve early warning of failures, the historical feature data obtained by the server can be data for at least two days before the circuit breaker, and the historical feature data on the day of the circuit breaker, the previous day, and the previous two days can be marked as positive samples, and the historical feature data from the previous three days and before can be marked as negative samples.
[0098] Furthermore, after obtaining the training feature data set and the verification feature data set, the server can perform model training and model verification on the fuse prediction model to obtain a trained fuse prediction model.
[0099] Specifically, after obtaining the training feature data set and the verification feature data set, the server can first oversample the training feature data set (Synthetic Minority Oversampling Technique, SMOTE), and then train the fuse prediction model through the oversampled training feature data set, adjust the model parameters according to the training results, and then verify the fuse prediction model through the verification feature data set, so as to obtain a trained fuse prediction model.
[0100] Optionally, S140 may specifically include: if the ranking of the predicted probability of the blown fuse is within a preset ranking range, and the predicted probability of the blown fuse is greater than or equal to a preset probability of the blown fuse corresponding to the preset ranking range, determining that the predicted probability of the blown fuse meets a preset probability condition.
[0101] In the embodiment of the present disclosure, after obtaining the fuse prediction probability, if the ranking of the fuse prediction probability is within a preset ranking range and the fuse prediction probability is greater than or equal to the preset fuse probability corresponding to the preset ranking range, the server determines that the fuse prediction probability meets the preset probability condition.
[0102] Optionally, the preset ranking range may be a predefined ranking range.
[0103] Optionally, the preset fuse probability can be a preset fuse probability corresponding to different preset ranking ranges. For example, there are 100 vehicles in a day, the top 10 vehicles are preset as the first preset ranking range, the top 11-30 vehicles are set as the second preset ranking range, the top 31-60 vehicles are set as the third preset ranking range, the top 61-100 vehicles are set as the fourth preset ranking range, etc., which are not limited here, and the first preset fuse probability corresponding to the first preset ranking range is set, and the preset fuse probability corresponding to each preset ranking range is set similarly.
[0104] For example, after obtaining the fuse prediction probability, the server can first determine the ranking of the fuse prediction probability among 100 vehicles in one day. If it is in the top 10, that is, the first preset ranking range, then determine whether the fuse prediction probability is greater than or equal to the first preset fuse probability corresponding to the first preset ranking range. For example, the fuse prediction probability can be 95%, and the first preset fuse probability can be 90%. At this time, the server can determine that the fuse prediction probability meets the preset probability condition, otherwise it does not meet the preset probability condition.
[0105] Therefore, only when the fuse prediction probability meets the preset probability conditions can the fuse of the target vehicle be predicted to have a blown event. Through double filtering and judgment, false alarms can be avoided, occasional vehicles with unstable probability output can be filtered out, and the accuracy of the prediction can be improved.
[0106] Optionally, after the server predicts that the fuse of the target vehicle has blown, the after-sales service can proactively recall the target vehicle and replace the fuse in advance. The replaced fuse can be X-rayed to determine whether it has melted severely based on internal testing. The test result should be used as a true label sample of the feature, which will be re-entered into the model training process to further improve the model coverage.
[0107] Figure 2 A schematic diagram of the structure of a fuse event prediction device provided by an embodiment of the present disclosure is shown.
[0108] In some embodiments of the present disclosure, Figure 2 The fuse event prediction device shown can be set in a server. Specifically, the server can include but is not limited to a cloud server or a cloud server cluster.
[0109] like Figure 2 As shown, the fuse event prediction device 200 may include a first acquisition module 210 , a first processing module 220 , a second processing module 230 and a fuse prediction module 240 .

[0112] The second processing module 230 can be used to input the target feature data into the trained fuse prediction model to obtain the fuse prediction probability output by the fuse prediction model.
[0113] The blown fuse prediction module 240 may be used to predict a blown fuse event of the target vehicle if the blown fuse prediction probability satisfies a preset probability condition.
[0114] Therefore, in the disclosed embodiment, the original data of the target vehicle within the target time period can be obtained, and the original data can be subjected to feature extraction processing to obtain target feature data, and then the target feature data is input into the trained fuse prediction model to obtain the fuse prediction probability output by the fuse prediction model. If the fuse prediction probability meets the preset probability condition, it is predicted that the fuse of the target vehicle will have a fuse blown event. Therefore, the original data can be subjected to feature extraction processing to obtain the target feature data, and the target feature data can be subjected to fuse prediction processing to obtain the fuse prediction probability. Finally, when the fuse prediction probability meets the preset probability condition, it is predicted that the fuse of the target vehicle will have a fuse blown event, thereby accurately predicting the fuse blown event and ensuring the safety of the vehicle while driving.

[0119] In some embodiments of the present disclosure, target characteristic data may include long time scale characteristic data.
[0120] In some embodiments of the present disclosure, the first processing module 220 may include a second statistical unit and a third statistical unit.

[0122] The third statistical unit can be used to obtain long-time scale characteristic data by counting the heat generation calculation value and the step overtemperature information within the second preset time based on the preset temperature threshold.
[0123] In some embodiments of the present disclosure, the target characteristic data may include full life cycle statistical characteristic data, and the full life cycle statistical characteristic data may include battery life information and vehicle mileage information.
[0124] In some embodiments of the present disclosure, the fuse event prediction device 200 may further include a second acquisition module, a label marking module and a model training module.
[0125] The second acquisition module can be used to acquire historical original data and perform feature extraction processing on the historical original data to obtain historical feature data before inputting the target feature data into the trained fuse prediction model.
[0126] The labeling module can be used to label historical feature data to obtain a training feature data set and a verification feature data set.

[0128] In some embodiments of the present disclosure, the fuse prediction module 240 can be specifically used to determine that the fuse prediction probability meets the preset probability condition if the ranking of the fuse prediction probability is within a preset ranking range and the fuse prediction probability is greater than or equal to the preset fuse probability corresponding to the preset ranking range.
