Description

[Technical Field]

[0001] This application relates to the field of vehicle technology, and in particular to a reliability testing method, related apparatus and storage medium for electrical components. [Background Technology]

[0002] Traditional methods of vehicle anomaly detection mainly rely on staff to check based on experience, which results in low work efficiency. [Summary of the Invention]

[0003] In view of the above problems, this application provides at least one method, related device and storage medium for reliability testing of electrical components, which can improve testing efficiency.

[0004] This application provides a reliability testing method for an electrical component, which is installed in an electrical device. The reliability testing method includes: acquiring first state information of the electrical component in the electrical device, the first state information being used to characterize the working environment of the electrical component; acquiring second state information of the electrical component, the second state information being used to characterize the working state of the electrical component under the first state information; comparing the second state information of the electrical component with standard state information of the electrical component, the standard state information being used to characterize the standard working state of the electrical component under the first state information; and determining the reliability of the electrical component based on the comparison result.

[0005] In the above scheme, by pre-recording the standard state information of the electrical components under each first state information, and then monitoring the second state information of the electrical components during the operation of the electrical device, and comparing the detected second state information with the corresponding standard state information under the first state information, the reliability of the electrical components can be determined based on the comparison result, eliminating the need for manual inspection and improving the efficiency of electrical component testing. Furthermore, by monitoring the second state information of the electrical components during their daily operation to determine their reliability, this scheme can reduce the occurrence of accidents to a certain extent, compared to analyzing the specific causes of accidents after problems emerge.

[0006] In some embodiments, the first state information includes external environmental parameters of the electrical component, the external environmental parameters including at least one of the operating states of several target components and environmental parameters of the environment in which the electrical device is located, the target components including other components in the electrical device besides the electrical component; and / or, the second state information includes energy consumption data, the standard state information including standard energy consumption data.

[0007] In the above scheme, because external environmental parameters may affect the second state information of the electrical components during operation, the first state information of the electrical components is determined by comprehensively considering external environmental parameters. This makes the determined first state information more accurate compared with the standard state data of the electrical components. Furthermore, by monitoring and comparing the energy consumption of the electrical components during operation, abnormal energy consumption may indicate a malfunction in the electrical components. Therefore, the reliability of the electrical components can be determined by monitoring differences in energy consumption.

[0008] In some embodiments, before comparing the second state information of the power-consuming component with the standard state information of the power-consuming component, the method further includes: determining other components in the power-consuming device that can affect the second state information of the power-consuming component as target components based on the circuit structure of the power-consuming device; and determining environmental parameters that can affect the second state information of the power-consuming component based on the working content of the power-consuming component; combining the working state of the power-consuming component, the working state of each target component, and each environmental parameter to obtain the first state information of the power-consuming component; and measuring the second state information of the power-consuming component when it is performing standard operation under the first state information as the standard state information.

[0009] In the above scheme, by analyzing the circuit structure of the electrical device, other components within the device that can affect the second state information of the electrical component can be identified, facilitating the determination of the first state information based on the operating states of these other components. Furthermore, by analyzing the operating conditions of the electrical component, environmental parameters that can influence its second state information can be determined, allowing for a comprehensive consideration of the impact of these environmental parameters on the component's operation, resulting in a more accurate final comparison.

[0010] In some embodiments, measuring the second state information of the electrical component when it is operating normally under the first state information as the standard state information includes: controlling the electrical component to operate under the first state information and measuring the state parameters of the electrical component multiple times; and statistically analyzing the state parameters under each first state information to obtain the standard state information corresponding to each first state information.

[0011] In the above scheme, the power-consuming components are controlled to work under the first state information, and the state parameters of the power-consuming components are measured multiple times. Then, the state parameters under each first state information are statistically analyzed, so that the standard state information corresponding to each first state information is more accurate.

[0012] In some embodiments, there are multiple first state information of electrical components, and different first state information represents different working environments of electrical components. The method further includes: acquiring standard state information of other electrical components in the electrical device under several other first state information, each other first state information being used to represent the working environment of other electrical components, and different other first state information representing different working environments of other electrical components; constructing a state parameter map of the electrical device using the standard state information of the electrical components under several first state information and the standard state information of other electrical components under various other first state information; comparing the second state information of the electrical components with the standard state information of the electrical components, including: determining the first state information in the state parameter map that matches the acquired first state information of the electrical components; and comparing the standard state information corresponding to the matched first state information with the monitored second state information of the electrical components.

[0013] In the above scheme, the standard state information of electrical components and other electrical components in the corresponding working environment can be recorded more intuitively by using state parameter graphs.

[0014] In some embodiments, before comparing the second state information of the power-consuming component with the standard state information of the power-consuming component, the method further includes: obtaining the standard state information of the power-consuming components in the power-consuming device and several other power-consuming devices when they are performing standard operation under each first state information; and for each first state information, statistically analyzing the second state information of the power-consuming components in each power-consuming device under the first state information to obtain the final standard state information of the power-consuming component under the first state information.

[0015] In the above scheme, by referring to the standard state information of the electrical components in each electrical device under the first state information, the final standard state information of the electrical components under the first state information is obtained, making the determined standard state information more accurate.

[0016] In some embodiments, the power-consuming component includes several life cycles, and each first state information in each life cycle corresponds to standard state information. Comparing the second state information of the power-consuming component with the standard state information of the power-consuming component includes: determining the target life cycle in which the power-consuming component in the power-consuming device is located; comparing the second state information of the power-consuming component with the standard state information corresponding to the first state information in the target life cycle to obtain a comparison result.

[0017] In the above scheme, by determining the corresponding standard state information for the first state information of each life cycle of the power-consuming component, the final determination of whether the power-consuming component is reliable is more accurate.

[0018] In some embodiments, the method further includes: acquiring comparison results of the power-consuming components at each life cycle; determining the expected failure time of the power-consuming components based on the changes in the comparison results at each life cycle; and sending the predicted failure time to a preset recipient.

[0019] In the above scheme, by obtaining the difference between the second state information and the corresponding standard state information of the power-consuming component in each life cycle, the aging of the power-consuming component can be reflected, and the expected failure time of the power-consuming component can be determined.

[0020] In some embodiments, each comparison result includes a target difference between second state information and standard state information. Based on the changes in the comparison results over each life cycle, the expected failure time of the power consumption component is determined, including: for each target difference, determining the ratio between the target difference and the energy consumption reliability data corresponding to the target difference; sorting each ratio according to the acquisition time of each target difference to obtain a difference change curve, wherein the first axis of the difference change curve represents the life cycle and the second axis of the difference change curve represents the ratio; and determining the failure time of the power consumption component based on the trend of the difference change curve over time, wherein the failure time is the time corresponding to the ratio being greater than or equal to a preset maximum ratio.

[0021] In the above scheme, the aging of the electrical component can be indirectly reflected by the change in the target difference over time, thereby determining the failure time of the electrical component. This failure time can provide a reference for upgrading and optimizing the electrical component during the production of subsequent batches of electrical devices.

[0022] In some embodiments, the comparison result includes the difference between second state information and standard state information. Based on the comparison result, the reliability of the power component is determined, including: determining whether the difference is greater than or equal to a preset difference threshold; in response to the difference being greater than or equal to the preset difference threshold, determining that the power component is unreliable; in response to the difference being less than the preset difference threshold, determining that the power component is reliable.

[0023] In the above scheme, when the difference is large, the power component is determined to be unreliable, and when the difference is small, the power component is determined to be reliable. This can determine whether the second state information of the power component is within a reasonable range.

[0024] In some embodiments, after determining the reliability of the power component based on the comparison results, the method further includes: in response to determining that the power component is unreliable, generating an alarm message to indicate that the power component is unreliable; and sending the alarm message to a preset recipient.

[0025] In the above scheme, by sending alarm information to a preset recipient to indicate that the electrical components are unreliable, the preset recipient can be informed of the relevant status of the electrical components in a timely manner.

[0026] This application provides a reliability testing device for electrical components, comprising: a first acquisition module, a second acquisition module, a comparison module, and a determination module; the first acquisition module is used to acquire first state information of the electrical components of the electrical device, the first state information being used to characterize the working environment of the electrical components; the second acquisition module is used to acquire second state information of the electrical components, the second state information being used to characterize the working state of the electrical components under the first state information; the comparison module is used to compare the second state information of the electrical components with standard state information of the electrical components, the standard state information being used to characterize the standard working state of the electrical components under the first state information; and the determination module is used to determine the reliability of the electrical components based on the comparison results.

[0027] This application provides an electrical device, including a memory and a processor, wherein the processor executes program instructions stored in the memory to implement the aforementioned reliability detection method for electrical components.

[0028] This application provides a computer-readable storage medium storing program instructions thereon, which, when executed by a processor, implement the aforementioned reliability detection method for electrical components.

[0029] In the above scheme, by pre-recording the standard state information of the electrical components under each first state information, and then monitoring the second state information of the electrical components during the operation of the electrical device, the reliability of the electrical components can be determined based on the comparison result, eliminating the need for manual inspection and improving the efficiency of electrical component testing. Furthermore, by monitoring the second state information of the electrical components during their daily operation to determine their reliability, this scheme can reduce the occurrence of accidents to a certain extent, compared to analyzing the specific causes of accidents after problems emerge.

Detailed Implementation Methods

[0037] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0038] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0039] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this document means two or more. Moreover, the term "at least one" in this document means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0040] The inventors of this solution discovered that traditional vehicle anomaly detection methods mainly rely on staff's experience for troubleshooting, which is inefficient. Therefore, a method to improve fault detection efficiency is needed.

[0041] Please see Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the reliability testing method for electrical components provided in this application. The electrical components are installed in an electrical device, such as... Figure 1 As shown, the reliability testing method for electrical components provided in this application may include the following steps S11 to S14, as detailed below:

[0042] Step S11: Obtain the first state information of the electrical components of the electrical device.

[0043] The electrical device can be any device that requires electricity, such as an electric car, an electric motorcycle, a robotic vacuum cleaner, etc. The specific type of electrical device is not specified here. The electrical component can be any component of the electrical device that requires electricity; for example, an electrical component can be a controller or a load. For example, the electrical device is a car, and the electrical component is the windshield wiper system within the car. The first state information is used to characterize the working environment of the electrical component, mainly representing the component's own and / or external environment during its current operation.

[0044] Step S12: Obtain the second state information of the power-consuming components.

[0045] The second state information is used to characterize the operating state of the electrical component under the first state information. For example, the operating state can be the operating condition of the electrical component, such as any parameter that can represent the operating condition of the electrical component.

[0046] Step S13: Compare the second state information of the power consumption component with the standard state information of the power consumption component.

[0047] Standard state information is used to characterize the standard operating state of an electrical component under the first state information. For example, standard state information can represent the standard operating state of an electrical component under the first state information. Standard operation can be understood as normal operation. Specifically, standard state information can be the second state information obtained by controlling the electrical component to operate under each first state information, provided that the component is reliable. The standard state information can be determined using manual detection or other existing detection methods; no specific details are provided here. "Same type of first state information" specifically means the same first state information. "Several" refers to one or more, such as two, five, ten, etc.

[0048] Step S14: Based on the comparison results, determine the reliability of the electrical components.

[0049] One method for determining the reliability of electrical components based on comparison results is as follows: if the difference between the second state information and the standard state information is too large, the electrical component is determined to be unreliable. If the difference is not large, the electrical component is determined to be reliable.

[0050] The above-described solution pre-records the standard state information of electrical components under each first state condition. Then, during the operation of the electrical device, it monitors the second state information of the components and compares the detected second state information with the corresponding standard state information under the first state condition. The reliability of the electrical component can be determined based on the comparison result, eliminating the need for manual inspection and improving the efficiency of component inspection. Furthermore, by monitoring the second state information of electrical components during daily operation to determine their reliability, this solution can reduce the occurrence of accidents to a certain extent, compared to analyzing the specific causes of accidents after problems emerge.

[0051] In some embodiments, the first state information includes external environmental parameters of the electrical components. The external environmental parameters include at least one of the operating states of several target components and environmental parameters of the environment in which the electrical device is located. Target components include other components in the electrical device besides the electrical components themselves.

[0052] The environmental parameters of the environment in which the electrical device is located can be parameters such as ambient temperature, humidity, and rainfall, etc., without specific limitations here. The electrical device may include multiple components that require power supply. Other components may be all components except the electrical component to be fault-predicted, or some components, without specific limitations here.

[0053] In the above scheme, since external environmental parameters may affect the second state information of the power-consuming components during operation, the first state information of the power-consuming components is determined by comprehensively considering the external environmental parameters, so that the determined first state information is more accurate than the standard state data of the power-consuming components.

[0054] In some embodiments, the first status information may further include the operating status of the power-consuming components.

[0055] The operating states of electrical components can be categorized based on their functions. For example, a windshield wiper system can function as intermittent, low-speed, or high-speed wipers, meaning its operating state is categorized according to the speed of its movement. The operating states of target components can also be categorized based on their functions, which will not be elaborated upon here. An electrical component may include at least one operating state.

[0056] In the above scheme, since the working state of the power-consuming component may affect the second state information of the power-consuming component during its operation, the first state information of the power-consuming component is determined by comprehensively considering the working state of the power-consuming component, so that the determined first state information is more accurate than the standard state data of the power-consuming component.

[0057] In some embodiments, the second state information includes energy consumption data, and the standard state information includes standard energy consumption data.

[0058] Energy consumption data can be any parameter that represents the energy consumption of an electrical component. For example, energy consumption data can be energy consumption (power), current, voltage, etc., per unit time. In some embodiments, energy consumption data can be a parameter representing the change in energy consumption of an electrical component. For example, energy consumption data can be the mean and variance of energy consumption data measured by the electrical component over a period of time. Wherein, when energy consumption data is a parameter representing the energy consumption of an electrical component, standard energy consumption data is also a parameter representing the energy consumption of the electrical component. For example, when energy consumption data is energy consumption per unit time, standard energy consumption data is also energy consumption per unit time. When energy consumption data is a parameter representing the change in energy consumption of an electrical component, standard energy consumption data is also a parameter representing the change in energy consumption of the electrical component. For example, energy consumption data can be the mean and variance of energy consumption data measured by the electrical component over a period of time, and standard energy consumption data can also be the mean and variance of energy consumption data measured by the electrical component over a period of time.

[0059] In the above scheme, by monitoring the comparison results of energy consumption between electrical components during operation, if the energy consumption is abnormal, it is very likely that the electrical component is abnormal. Therefore, the reliability of the electrical component can be determined by the difference in energy consumption.

[0060] In some embodiments, before performing step S13 above, the following steps may also be performed: based on the circuit structure of the electrical device, other components in the electrical device that can affect the second state information of the electrical component are identified as target components. And based on the operating content of the electrical component, environmental parameters that can affect the second state information of the electrical component are determined. Then, the operating state of the electrical component, the operating states of each target component, and each environmental parameter are combined to obtain the first state information of the electrical component. Next, the second state information of the electrical component when it is operating under standard conditions under the first state information is measured as standard state information.

[0061] Optionally, the target component may include at least one operating state. Optionally, based on the circuit structure of the electrical device, determining other components in the electrical device that can influence the second state information of the electrical component as target components can be achieved by inputting the circuit structure of the electrical device into an analysis model, and then the analysis model outputs the identifier of the target component by analyzing and processing the circuit structure. In other embodiments, the identifiers of other components input by the user can also be received as target components. The operating content of the electrical component can be determined based on the functions that the electrical component can perform and its operating location. For example, the electrical component is a windshield wiper. Since the windshield wiper operates at the windshield of the electrical device, it is easily affected by environmental parameters such as wind resistance and low temperature, leading to fluctuations in its energy consumption. The method of combining the operating states of the electrical component, the operating states of each target component, and each environmental parameter can be that the execution device of this solution combines each parameter one by one to obtain each set of first state information. Alternatively, it can be that several sets of first state information input by the user are received as the first state information of the electrical component.

[0062] In the above scheme, by analyzing the circuit structure of the electrical device, other components within the device that can affect the second state information of the electrical component can be identified, facilitating the determination of the first state information based on the operating states of these other components. Furthermore, by analyzing the operating conditions of the electrical component, environmental parameters that can influence its second state information can be determined, allowing for a comprehensive consideration of the impact of these environmental parameters on the component's operation, resulting in a more accurate final comparison.

[0063] In some embodiments, the method of using the second state information of the electrical component when it is operating normally under the first state information as the standard state information can be as follows: control the electrical component to operate under the first state information and measure the state parameters of the electrical component multiple times. Statistical analysis is performed on the state parameters under each first state information to obtain the standard state information corresponding to each first state information.

[0064] "Multiple times" refers to two or more times, such as ten times, twenty times, etc. The statistical method can be any data statistical method, such as calculating the average value and using the calculated average as the standard state information. It can also be any statistical value such as the maximum, minimum, median, or mode as the standard state information. For example, the root mean square and variance of each second state information are calculated and used as the standard state information. In some application scenarios, an energy consumption range can be determined using the root mean square and variance, and this energy consumption range is used as the final standard state information. Step S12 can specifically compare the measured energy consumption range with the energy consumption range under the first state information to obtain a comparison result. In other application scenarios, step S12 can directly compare the measured mean and variance with the mean and variance under the first state information to obtain a comparison result.

[0065] In the above scheme, the power-consuming components are controlled to work under the first state information, and the state parameters of the power-consuming components are measured multiple times. Then, the state parameters under each first state information are statistically analyzed, so that the standard state information corresponding to each first state information is more accurate.

[0066] In some embodiments, there are multiple first state information entries for electrical components, and different first state information entries represent different operating environments of the electrical components. The method further includes: acquiring standard state information of other electrical components in the electrical device under several other first state information entries, where each other first state information entry is used to characterize the operating environment of the other electrical components, and different other first state information entries characterize different operating environments of the other electrical components. A state parameter map of the electrical device is constructed using the standard state information of the electrical components under several first state information entries and the standard state information of other electrical components under various other first state information entries. The method for comparing the second state information of the electrical components with the standard state information of the electrical components can be as follows: first, determine the first state information in the state parameter map that matches the acquired first state information of the electrical components. Then, compare the standard state information corresponding to the matched first state information with the monitored second state information of the electrical components.

[0067] Other electrical components in an electrical device may include other components that need to be monitored. The status parameter maps corresponding to each electrical component in the electrical device are summarized to obtain the status parameter map corresponding to the electrical device. The summarization can be done by any method, such as splicing or merging. In some embodiments, a user's command to view the status parameter map of the electrical device is received, and the status parameter map of the electrical device is displayed at a preset display position on the electrical device, or the status parameter map of the electrical device is sent to a preset receiver. This method allows users to conveniently view the overall status of the electrical device in a timely manner.

[0068] In the above scheme, the standard state information of electrical components and other electrical components in the corresponding working environment can be recorded more intuitively by using state parameter graphs.

[0069] In some embodiments, the standard state information corresponding to each first state information of an electrical component can be recorded in the form of a state parameter graph. The state parameter graph can record the standard state information of a single electrical component in the electrical device under each first state information, or it can record the standard state information of multiple electrical components in the electrical device under their respective corresponding first state information. The specific form of the state parameter graph can be a table, a knowledge graph, etc., as long as it can record each first state information and the standard state information of the electrical component under the first state information. No specific limitation is made here regarding the form of the state parameter graph.

[0070] In the above scheme, it is more intuitive to record the standard state information of the power components under each first state information by using a state parameter graph.

[0071] Please see Figure 2 , Figure 2 This is a partial flowchart illustrating an embodiment of the reliability testing method for electrical components provided in this application. Figure 2 As shown, in some embodiments, the following steps may also be performed before performing step S13 above:

[0072] Step S21: Obtain the standard status information of the electrical device and the electrical components in several other electrical devices when they are operating under the first status information.

[0073] Step S22: For each first state information, the second state information of the electrical components in each electrical device under the first state information is statistically analyzed to obtain the final standard state information of the electrical components under the first state information.

[0074] In some embodiments, the other electrical devices are those from the same production batch as the current electrical device. In other embodiments, the other electrical devices may not be from the same production batch as the current electrical device. For example, the electrical device is a vehicle, and the other electrical devices are also vehicles; specifically, the other electrical devices may be vehicles from the same production batch as the current vehicle. The method for obtaining the standard state information of the electrical device and its components under each first state information during standard operation can refer to the method described above for obtaining the standard state information of the electrical device under each first state information, and will not be repeated here. The method for statistically analyzing the second state information of the electrical components in each electrical device under each first state information can also refer to the statistical method described above, for example, performing average value statistics and using the calculated average value as the standard state information. Alternatively, any statistical value such as the maximum value, minimum value, median value, or mode value can be used as the standard state information; please refer to the above for details, and will not be repeated here. For example, by summarizing and statistically analyzing the state parameter maps of each individual electrical device, the state parameter map for that batch can be obtained. The energy consumption data for that batch records the statistical results, which are the final standard state information under each first state information.

[0075] Furthermore, by statistically analyzing the standard state information of electrical components in each electrical device under each first state information, a state parameter spectrum for the batch is obtained, which can also be used to judge the electrical components in a single electrical device. Optionally, during the statistical process, electrical devices with potentially unreliable electrical components can also be identified. For example, electrical devices with state parameters far from the statistical mean are considered as unreliable electrical components. By analyzing the deviation characteristics of the state parameter spectrum of the electrical components under a single electrical device from the state parameter spectrum of the batch of electrical devices exceeding the threshold, the potential faulty single electrical device and its corresponding electrical components (e.g., controllers or electrical equipment) in the batch of vehicles can be predicted. By identifying electrical devices with potential faults in the batch of electrical devices, the causes of potential faults can be investigated through routine maintenance, eliminating potential faults without the customer's awareness, thereby improving the customer's trust in the quality of the electrical devices.

[0076] In the above scheme, by referring to the standard state information of the electrical components in each electrical device under the first state information, the final standard state information of the electrical components under the first state information is obtained, making the determined standard state information more accurate.

[0077] In some embodiments, the electrical component includes several lifecycles, and each first state information in each lifecycle corresponds to standard state information. Step S12 may include the following steps: determining the target lifecycle of the electrical component in the electrical device; then comparing the second state information of the electrical component with the standard state information corresponding to the first state information in the target lifecycle to obtain a comparison result.

[0078] The lifecycle of electrical components can be divided according to demand. For example, for vehicles, every N years after production and market launch can be considered a lifecycle. Standard state information for each electrical component under each first state information is calculated within each lifecycle. Then, standard state information for comparison is determined based on the target lifecycle of the electrical component. In some application scenarios, since the standard state information for normal operation of an electrical component under the first state information can be obtained from a single electrical device or from statistics of a batch of electrical devices, the standard state information corresponding to each first state information under the electrical lifecycle can also be obtained from a single electrical device or from statistics of a batch of electrical devices.

[0079] In the above scheme, by determining the corresponding standard state information for the first state information of each life cycle of the power-consuming component, the final determination of whether the power-consuming component is reliable is more accurate.

[0080] In some embodiments, comparison results of the electrical components are obtained at each stage of their lifecycle. Then, based on the changes in the comparison results at each stage of their lifecycle, the estimated failure time of the electrical components is determined. The predicted failure time can then be sent to a predetermined recipient.

[0081] The methods for obtaining comparison results of electrical components at each stage of their lifecycle can be referenced above and will not be repeated here. Changes in the comparison results across each lifecycle represent the changes in the comparison results over the lifecycle of the electrical components. Failure time can be considered as the time after which the electrical component becomes unreliable. The preset recipient can be the owner of the electrical device or the manufacturer of the electrical device; the specific preset recipient can be set according to requirements and is not specifically limited here.

[0082] In the above scheme, by obtaining the difference between the second state information and the corresponding standard state information of the power-consuming component in each life cycle, the aging of the power-consuming component can be reflected, and the expected failure time of the power-consuming component can be determined.

[0083] In some embodiments, each comparison result includes a target difference between second state information and standard state information. The estimated failure time of an electrical component can be determined based on the changes in the comparison results throughout its lifecycle by: for each target difference, determining the ratio between the target difference and the corresponding energy consumption reliability data; then, sorting the ratios according to the acquisition time of each target difference to obtain a difference variation curve. The first axis of the difference variation curve represents the lifecycle, and the second axis represents the ratio. Finally, based on the trend of the difference variation curve over time, the failure time of the electrical component is determined, where the failure time is the time corresponding to a ratio greater than or equal to a preset maximum ratio.

[0084] As mentioned above, the second state information can include energy consumption data, and the standard state information can include standard energy consumption data. The target difference is the difference between the energy consumption data and the standard energy consumption data. For example, taking energy consumption data as any parameter representing the energy consumption of an electrical component, the parameter representing the change in energy consumption of the electrical component can be seen in the following example, which will not be elaborated upon here. For instance, the second state information is the first power per unit time, and the standard state information is also the second power per unit time. The target difference is the difference between the two power values, and the ratio is the ratio between this difference and the second power. Then, according to the acquisition time of each target difference, the ratios are sorted to obtain the difference change curve. For example, fitting each ratio over time yields the difference change curve, which can represent the change of the ratio over its life cycle. The specific value of the preset ratio can be determined experimentally and is not specifically specified here.

[0085] In the above scheme, the aging of the electrical component can be indirectly reflected by the change in the target difference over time, thereby determining the failure time of the electrical component. This failure time can provide a reference for upgrading and optimizing the electrical component during the production of subsequent batches of electrical devices.

[0086] In some embodiments, the comparison result includes the difference between the second state information and the standard state information. The method for determining the reliability of an electrical component based on the comparison result can be: determining whether the difference is greater than or equal to a preset difference threshold; in response to the difference being greater than or equal to the preset difference threshold, determining that the electrical component is unreliable; in response to the difference being less than the preset difference threshold, determining that the electrical component is reliable.

[0087] As mentioned above, the second state information may include energy consumption data, and the standard state information may include standard energy consumption data. The difference is the difference between the energy consumption data and the standard energy consumption data. The preset difference threshold can be determined experimentally and is not specifically limited here. "Unreliable" means that the probability of the electrical component malfunctioning is high, while "reliable" means that the probability of the electrical component malfunctioning is low.

[0088] In the above scheme, when the difference is large, the power component is determined to be unreliable, and when the difference is small, the power component is determined to be reliable. This can determine whether the second state information of the power component is within a reasonable range.

[0089] In some embodiments, after determining the reliability of the power component based on the comparison results, the method further includes: in response to determining that the power component is unreliable, generating an alarm message to indicate that the power component is unreliable; and sending the alarm message to a preset recipient.

[0090] In the above scheme, by sending alarm information to a preset recipient to indicate that the electrical components are unreliable, the preset recipient can be informed of the relevant status of the electrical components in a timely manner.

[0091] To better understand the reliability testing method for electrical components provided in this embodiment, please refer to the following example. In this example, the electrical device is a vehicle, the electrical component is a controller or electrical equipment in the vehicle, the first state information is the scenario (working state) and environmental condition parameters of the electrical component, and the second state information is energy consumption data.

[0092] First, we analyze the scenarios that cause different energy consumption of each controller or electrical device under normal conditions. Based on different scenarios, we analyze the quantifiable environmental condition parameters that may lead to changes in energy consumption. By repeating the experiment and recording the energy consumption values ​​of each controller or electrical device after superimposing different scenarios and environmental condition parameters, we calculate the root mean square and variance values ​​of energy consumption under each superimposed condition. These root mean square and variance values ​​are used as the state parameter maps of each controller or electrical device. By summarizing the state parameter maps of each controller or electrical device, we obtain the state parameter map of the whole vehicle.

[0093] For example, the power consumption of the windshield wiper system varies depending on the scenario: wipers off, intermittent wiping, low-speed wiping, and high-speed wiping. Under identical environmental conditions, the current consumed by the wiper system differs in these scenarios. Within any of these scenarios, the current consumed by the wiper system also varies under different vehicle speeds, rainfall levels, power supply voltages, and temperatures. By conducting experiments on the wiper system under various conditions—wiping modes, vehicle speed, rainfall, power supply voltage, and ambient temperature—and recording the current consumption under different conditions, the energy consumption value for each specific scenario is obtained by multiplying the current by the wiper system voltage. The root mean square (RMS) and variance of the energy consumption values ​​obtained from multiple repeated experiments are calculated, and these RMS and variance values ​​are used as the state parameter map of the wiper system. Using the same analysis and experimental methods, the state parameter maps of all controllers or electrical devices in the vehicle are obtained. Finally, the state parameter maps of all controllers or electrical devices are combined to obtain the overall vehicle state parameter map.

[0094] During vehicle operation, the power consumption of each controller or electrical device is monitored in real time, and the corresponding scenario and environmental condition parameters are recorded. The root mean square and variance values ​​of energy consumption under the corresponding scenario and environmental conditions are found in the energy spectrum of the controller or electrical device, and the root mean square and variance of the real-time monitored energy consumption are calculated. When the real-time monitoring deviates from the value in the energy spectrum and the deviation exceeds a certain threshold, it indicates that the energy consumption of the controller or electrical device is abnormal. Based on this, it is determined that the controller or electrical device has a potential fault and is on the verge of functional failure.

[0095] In some application scenarios, the power consumption of each controller or electrical device in a batch of vehicles is monitored under various actual usage scenarios and environmental conditions over a period of time. The corresponding scenarios and environmental conditions are recorded, and the root mean square (RMS) and variance of the energy consumption of the batch of vehicles under each superimposed condition are calculated. These RMS and variance values ​​serve as the state parameter maps of each controller or electrical device in the batch of vehicles. The state parameter maps of each controller or electrical device are then aggregated to obtain the state parameter map of the entire batch of vehicles. When the power consumption of a controller or electrical device in a single vehicle deviates from the data in the state parameter map of the batch of vehicles under normal conditions, and the deviation exceeds a certain threshold, it indicates that the energy consumption of the corresponding controller or electrical device is abnormal. Based on this, it is determined that the controller or electrical device has a potential fault and is on the verge of functional failure.

[0096] In some application scenarios, the energy consumption data of each controller or electrical device in a batch of vehicles is monitored throughout the vehicle's entire life cycle. These monitoring data form a trend line (difference change curve) that gradually deviates from the energy spectrum as the vehicle ages. This trend line represents the aging of each controller and electrical device in the vehicle. The intersection of its trend extension line and the energy consumption ratio (preset ratio) represents the expected failure time of the controller or electrical device.

[0097] The above-described solution pre-records the standard state information of electrical components under each first state condition. Then, during the operation of the electrical device, it monitors the second state information of the components and compares the detected second state information with the corresponding standard state information under the first state condition. The reliability of the electrical component can be determined based on the comparison result, eliminating the need for manual inspection and improving the efficiency of component inspection. Furthermore, by monitoring the second state information of electrical components during daily operation to determine their reliability, this solution can reduce the occurrence of accidents to a certain extent, compared to analyzing the specific causes of accidents after problems emerge.

[0098] In addition, by anticipating potential vehicle malfunctions in advance, users can avoid malfunctions during vehicle use, thereby improving the user experience and driving safety.

[0099] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0100] In the several embodiments provided in this application, it should be understood that the disclosed methods and apparatus can be implemented in other ways. For example, the apparatus implementations described above are merely illustrative. For instance, the division of modules or units is only a logical functional division, and in actual implementation, there may be other division methods. For example, units or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the mutual coupling or direct coupling or communication connection shown or discussed may be through some interfaces; the indirect coupling or communication connection of devices or units may be electrical, mechanical, or other forms.

[0101] The entity performing fault prediction can be a reliability testing device for electrical components. For example, this device could be a terminal device, a server, or other processing equipment. This reliability testing device can be applied to electrical devices. Terminal devices can include user equipment (UE), computers, mobile devices, user terminals, terminals, cellular phones, cordless phones, personal digital assistants (PDAs), handheld devices, computing devices, in-vehicle devices, wearable devices, etc. In some possible implementations, the reliability testing method for electrical components can be implemented by a processor calling computer-readable instructions stored in memory.

[0102] Please see Figure 3 , Figure 3 This is a schematic diagram of an embodiment of the reliability testing device for electrical components provided in this application. The reliability testing device 30 for electrical components includes a first acquisition module 31, a second acquisition module 32, a comparison module 33, and a determination module 34; the first acquisition module 31 is used to acquire first state information of the electrical components of the electrical device, the first state information being used to characterize the working environment of the electrical components; the second acquisition module 32 is used to acquire second state information of the electrical components, the second state information being used to characterize the working state of the electrical components under the first state information; the comparison module 33 is used to compare the second state information of the electrical components with the standard state information of the electrical components, the standard state information being used to characterize the standard working state of the electrical components under the first state information; the determination module 34 is used to determine the reliability of the electrical components based on the comparison results.

[0103] The above-described solution pre-records the standard state information of electrical components under each first state condition. Then, during the operation of the electrical device, it monitors the second state information of the components and compares the detected second state information with the corresponding standard state information under the first state condition. The reliability of the electrical component can be determined based on the comparison result, eliminating the need for manual inspection and improving the efficiency of component inspection. Furthermore, by monitoring the second state information of electrical components during daily operation to determine their reliability, this solution can reduce the occurrence of accidents to a certain extent, compared to analyzing the specific causes of accidents after problems emerge.

[0104] In some embodiments, the first state information includes external environmental parameters of the electrical components. These external environmental parameters include at least one of the operating states of several target components and environmental parameters of the environment in which the electrical device is located. The target components include other components in the electrical device besides the electrical components themselves. In some embodiments, the second state information includes energy consumption data, and the standard state information includes standard energy consumption data.

[0105] In the above scheme, because external environmental parameters may affect the second state information of the electrical components during operation, the first state information of the electrical components is determined by comprehensively considering external environmental parameters. This makes the determined first state information more accurate compared with the standard state data of the electrical components. Furthermore, by monitoring and comparing the energy consumption of the electrical components during operation, abnormal energy consumption may indicate a malfunction in the electrical components. Therefore, the reliability of the electrical components can be determined by monitoring differences in energy consumption.

[0106] In some embodiments, before acquiring the first state information of the power-consuming components of the power-consuming device and monitoring the second state information of the power-consuming components, the parameter acquisition module 31 is further configured to: determine other components in the power-consuming device that can affect the second state information of the power-consuming components as target components based on the circuit structure of the power-consuming device, and determine environmental parameters that can affect the second state information of the power-consuming components based on the working content of the power-consuming components; combine the working state of the power-consuming components, the working state of each target component, and each environmental parameter to obtain the first state information of the power-consuming components; and measure the second state information of the power-consuming components when performing standard operation under the first state information as standard state information.

[0107] In the above scheme, by analyzing the circuit structure of the electrical device, other components within the device that can affect the second state information of the electrical component can be identified, facilitating the determination of the first state information based on the operating states of these other components. Furthermore, by analyzing the operating conditions of the electrical component, environmental parameters that can influence its second state information can be determined, allowing for a comprehensive consideration of the impact of these environmental parameters on the component's operation, resulting in a more accurate final comparison.

[0108] In some embodiments, the parameter acquisition module 31 measures the second state information of the power-consuming component when it is operating in a standard manner under the first state information as the standard state information, including: controlling the power-consuming component to operate under the first state information and measuring the state parameters of the power-consuming component multiple times; and statistically analyzing the state parameters under each first state information to obtain the standard state information corresponding to each first state information.

[0109] In the above scheme, the power-consuming components are controlled to work under the first state information, and the state parameters of the power-consuming components are measured multiple times. Then, the state parameters under each first state information are statistically analyzed, so that the standard state information corresponding to each first state information is more accurate.

[0110] In some embodiments, the parameter acquisition module 31 is further configured to: acquire standard state information of other electrical components in the electrical device under several other first state information; and construct a state parameter map of the electrical device using the standard state information of the electrical components under several first state information and the standard state information of other electrical components under other first state information. The comparison module 32 compares the second state information of the electrical components with the standard state information of the electrical components, including: determining the first state information in the state parameter map that matches the acquired first state information of the electrical components; and comparing the standard state information corresponding to the matched first state information with the monitored second state information of the electrical components.

[0111] In the above scheme, the standard state information of electrical components and other electrical components in the corresponding working environment can be recorded more intuitively by using state parameter graphs.

[0112] In some embodiments, before comparing the second state information of the power-consuming component with the standard state information of the power-consuming component, the parameter acquisition module 31 is further configured to: acquire the standard state information of the power-consuming component in the power-consuming device and several other power-consuming devices when performing standard operation under each first state information, wherein the other power-consuming devices are power-consuming devices in the same production batch as the power-consuming device; and for each first state information, statistically analyze the second state information of the power-consuming component in each power-consuming device under the first state information to obtain the final standard state information of the power-consuming component under the first state information.

[0113] In the above scheme, by referring to the standard state information of the electrical components in each electrical device under the first state information, the final standard state information of the electrical components under the first state information is obtained, making the determined standard state information more accurate.

[0114] In some embodiments, the power-consuming component includes several life cycles, and each first state information in each life cycle corresponds to standard state information. The comparison module 32 compares the second state information of the power-consuming component with the standard state information of the power-consuming component, including: determining the target life cycle in which the power-consuming component is located in the power-consuming device; comparing the second state information of the power-consuming component with the standard state information corresponding to the first state information in the target life cycle to obtain a comparison result.

[0115] In the above scheme, by determining the corresponding standard state information for the first state information of each life cycle of the power-consuming component, the final determination of whether the power-consuming component is reliable is more accurate.

[0116] In some embodiments, the comparison module 32 is further configured to acquire the comparison results of the power consumption components at each life cycle. The determination module 33 is further configured to determine the expected failure time of the power consumption components based on the changes in the comparison results at each life cycle; and send the predicted failure time to a preset receiver.

[0117] In the above scheme, by obtaining the difference between the second state information and the corresponding standard state information of the power-consuming component in each life cycle, the aging of the power-consuming component can be reflected, and the expected failure time of the power-consuming component can be determined.

[0118] In some embodiments, each comparison result includes a target difference between second state information and standard state information. The comparison module 32 determines the expected failure time of the power consumption component based on the changes in the comparison results in each life cycle, including: for each target difference, determining the ratio between the target difference and the energy consumption reliability data corresponding to the target difference; sorting each ratio according to the acquisition time of each target difference to obtain a difference change curve, wherein the first axis of the difference change curve represents the life cycle and the second axis of the difference change curve represents the ratio; and taking the time corresponding to the intersection of the extension line of the difference change curve and the straight line where the preset ratio is located as the failure time, wherein the straight line where the preset ratio is located is parallel to the first axis.

[0119] In the above scheme, the aging of the electrical component can be indirectly reflected by the change in the target difference over time, thereby determining the failure time of the electrical component. This failure time can provide a reference for upgrading and optimizing the electrical component during the production of subsequent batches of electrical devices.

[0120] In some embodiments, the comparison result includes the difference between the second state information and the standard state information. Based on the comparison result, the determination module 33 determines the reliability of the power component, including: determining whether the difference is greater than or equal to a preset difference threshold; in response to the difference being greater than or equal to the preset difference threshold, determining that the power component is unreliable; in response to the difference being less than the preset difference threshold, determining that the power component is reliable.

[0121] In the above scheme, when the difference is large, the power component is determined to be unreliable, and when the difference is small, the power component is determined to be reliable. This can determine whether the second state information of the power component is within a reasonable range.

[0122] In some embodiments, after determining the reliability of the power component based on the comparison results, the determining module is further configured to include: generating an alarm message to indicate that the power component is unreliable in response to determining that the power component is unreliable; and sending the alarm message to a preset recipient.

[0123] In the above scheme, by sending alarm information to a preset recipient to indicate that the electrical components are unreliable, the preset recipient can be informed of the relevant status of the electrical components in a timely manner.

[0126] The above-described solution pre-records the standard state information of electrical components under each first state condition.
