Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0035] Before detailing the specific implementation methods of this disclosure, the application scenarios of this disclosure are first described below. This disclosure can be applied to autonomous driving systems for monitoring communication links. Real-time monitoring of communication links not only ensures the timeliness of data processing but also its accuracy, thereby promptly identifying and resolving potential computational latency issues and effectively preventing safety risks. In related technologies, the configuration files for different vehicle models and versions of intelligent driving hardware are usually fixed, and these configuration files include the fixed communication links being monitored. When the monitored communication links are updated, the configuration files need to be manually adjusted and updated, resulting in low flexibility and scalability of the configuration files.

[0036] To address the aforementioned issues, the solution disclosed herein determines the link level identifier and monitoring level identifier of each communication link in a preset configuration file. Based on these identifiers, the link to be monitored is dynamically determined, which effectively improves the flexibility and scalability of communication link monitoring, thereby enhancing vehicle safety and reliability.

[0037] Figure 1 This is a flowchart illustrating a communication link monitoring method according to an exemplary embodiment, such as... Figure 1 As shown, the communication link monitoring method is applied to a vehicle, which includes at least one communication link, and includes the following steps.

[0038] In step 101, the link level identifier of the preset configuration file for each communication link is determined.

[0039] The preset configuration file includes the link level field, and different link level identifiers are used to represent different levels of attention.

[0040] In this step, the preset configuration file for each communication link contains a link level identifier, which is used to indicate the link's level of attention. The target level identifier corresponding to the link level field in the preset configuration file is determined, and the target level identifier is used as the link level identifier in the preset configuration file.

[0041] It should be noted that the preset configuration file can be dynamically updated by changing the link level identifier of the communication link.

[0042] In step 102, the monitoring level identifier for each communication link is determined.

[0043] The monitoring level identifier can be used to characterize the level of attention paid to the communication link, and can be represented by numbers (such as 0, 1, 2) or characters (such as A, B, C).

[0044] In this step, the vehicle model information corresponding to the vehicle can be obtained; based on the vehicle model information, the monitoring level identifier of each communication link is determined from the preset correspondence data, the correspondence data including the monitoring level identifier of each communication link corresponding to each vehicle model.

[0045] In step 103, for each communication link, if it is determined that the communication link belongs to the link to be monitored based on the link level identifier and the monitoring level identifier of the communication link, the preset configuration file of the communication link is input into the preset link monitoring server.

[0046] The preset link monitoring server is used to monitor the communication link. The link level identifier is used to characterize the level of attention paid to the communication link. The monitoring level identifier can be used to characterize the level of attention paid to monitoring the communication link.

[0047] In this step, a first level of concern corresponding to the link level identifier and a second level of concern corresponding to the monitoring level identifier are determined. If the first level of concern is less than or equal to the second level of concern, the communication link is determined to belong to the link to be monitored. The preset configuration file of the link to be monitored is input into the preset link monitoring server, and the link to be monitored is monitored through the preset link monitoring server.

[0048] The above technical solution, by determining the link level identifier and monitoring level identifier of each communication link in the preset configuration file, and dynamically determining the link to be monitored based on the link level identifier and monitoring level identifier of each communication link, can effectively improve the flexibility and scalability of communication link monitoring, thereby effectively improving the safety and reliability of vehicles.

[0049] Figure 2 It is based on Figure 1 The illustrated embodiment presents a flowchart of a communication link monitoring method. The preset configuration file includes the link-level field, such as... Figure 2 As shown, Figure 1 Step 101, which involves determining the link level identifier of the preset configuration file for each communication link, may include: Step 1011: Determine the target level identifier corresponding to the link level field in the preset configuration file.

[0050] The target level identifier is used to characterize the level of the communication link.

[0051] For example, PATH_LEVEL_RELEASE=0; PATH_LEVEL_PRO=1; PATH_LEVEL_MAX=2; PATH_LEVEL_DEVELOP=3. Here, PATH_LEVEL_RELEASE, PATH_LEVEL_PRO, PATH_LEVEL_MAX, and PATH_LEVEL_DEVELOP are the link-level fields in the preset configuration file, and 0, 1, 2, and 3 are the target-level identifiers corresponding to the link-level fields in the preset configuration file.

[0052] Step 1012: Use the target level identifier as the link level identifier of the preset configuration file.

[0053] The above technical solution determines the link level identifier of the communication link based on the target level identifier corresponding to the link level field in the preset configuration file, providing a basis for dynamically determining the link to be monitored in the future.

[0054] Optionally, Figure 1 The preset configuration file can be accessed through Figure 3 The steps shown are updated in real time. Figure 3 It is based on Figure 1 The flowchart of another communication link monitoring method shown in the embodiment is as follows: Figure 3 As shown, the communication link monitoring method may further include: S1, Obtain historical operation data for each of the communication links.

[0055] The historical operational data may include abnormal indicator data.

[0056] In this step, historical operational data is collected from each communication link during the historical operating period. This historical operational data includes, but is not limited to, monitoring parameters such as transmission rate, CPU utilization, and computation latency. The number of times each communication link was monitored during the historical operating period, as well as the monitoring parameters of the communication link at each monitoring time, are obtained. Based on the monitoring parameters of each communication link and a preset parameter range, abnormal indicator data for each communication link are determined.

[0057] S2, for each of the communication links, determine the upper confidence limit of the communication link based on the abnormal indicator data of the communication link.

[0058] The confidence upper limit is used to characterize the uncertainty of the communication link.

[0059] In this step, the total number of monitoring times is determined based on the number of monitoring times for each communication link. A target number of abnormal index data occurrences is determined for each communication link. Based on the number of monitoring times for each communication link and the target number of abnormal occurrences, the total number of monitoring times determines the upper confidence limit for each communication link.

[0060] S3, determine the current link level of the communication link based on the upper confidence limit of the communication link.

[0061] The confidence limit is used to characterize the uncertainty of the communication link. The higher the uncertainty of the communication link, the higher the current link level of the communication link.

[0062] In one implementation, determining the current link level of the communication link based on the upper confidence limit of the communication link may include: if the upper confidence limit is greater than a preset upper confidence limit threshold, obtaining the number of nodes in the communication link; if the number of nodes is greater than a preset node number threshold, identifying abnormal nodes in the communication link from the at least one node; dividing the communication link into abnormal sub-links and non-abnormal sub-links based on the abnormal nodes; determining the current link level of the abnormal sub-link as a first level, and determining the current link level of the non-abnormal sub-link as a second level, wherein the attention level corresponding to the first level is greater than the attention level corresponding to the second level.

[0063] In another implementation, determining the current link level of the communication link based on the upper confidence limit of the communication link may further include: when the number of nodes is less than or equal to a preset node number threshold, determining the target upper confidence limit range to which the upper confidence limit of the communication link belongs; and using the link level corresponding to the target upper confidence limit range as the current link level of the communication link.

[0064] In another embodiment, determining the current link level of the communication link based on the upper confidence limit of the communication link may further include: if the upper confidence limit of the communication link is less than or equal to a preset upper confidence limit threshold, determining the target upper confidence limit range to which the upper confidence limit of the communication link belongs; and using the link level corresponding to the target upper confidence limit range as the current link level of the communication link.

[0065] S4, Generate the preset configuration file according to the current link level.

[0066] In this step, for each communication link, the initial configuration file of the communication link and the level identifier corresponding to the current link level of the communication link are obtained; the field value of the link level field is generated according to the level identifier; the link level field and the field value of the link level field are added to the initial configuration file to obtain the preset configuration file.

[0067] The above technical solution determines the upper confidence limit of the communication link based on the abnormal indicator data, determines the current link level of the communication link, and generates the preset configuration file, providing a basis for subsequently determining the link level identifier of the communication link from the preset configuration file.

[0068] Figure 4 It is based on Figure 3 The illustrated embodiment presents a flowchart of a communication link monitoring method, as shown below. Figure 4 As shown, Figure 3As described in S1, obtaining historical operational data for each of the communication links, the historical operational data includes abnormal indicator data, and may further include: S11, obtain the number of times each communication link was monitored during the historical operating period, and the monitoring parameters of the communication link during each monitoring.

[0069] The monitoring parameters may include CPU utilization and computation latency.

[0070] In this step, initially, each communication link is run for a preset period of time, and monitoring parameters in each communication link are monitored. Based on the abnormal indicator data of the communication links, a confidence upper limit value is determined for each communication link. The confidence upper limits of each communication link are compared to determine the first confidence upper limit value with the largest confidence upper limit value, and the first communication link corresponding to the first confidence upper limit value is determined. The first communication link is re-monitored, and its confidence upper limit value is recalculated. The confidence upper limits of each communication link are compared again to determine the second confidence upper limit value with the largest confidence upper limit value, and the second communication link corresponding to the second confidence upper limit value is determined. Monitoring of the communication links stops when the number of monitoring times for each communication link meets a predetermined number of observations, or when other stopping conditions are met (such as convergence of confidence upper limits values ​​for all communication links). The number of monitoring times for each communication link within the historical operating period is determined.

[0071] S12, determine the abnormal indicator data of each communication link based on the monitoring parameters of each communication link and the preset parameter range.

[0072] The monitoring parameters may include at least CPU utilization and computation latency.

[0073] In this step, the preset parameter range of the monitoring parameters is obtained. If any of the monitoring parameters exceeds the preset parameter range, it can be considered that there is abnormal indicator data in the communication link.

[0074] For example, the preset CPU utilization range is no more than 70%, and the preset computation latency is no more than 10 milliseconds. The communication link includes 20 nodes. The CPU utilization of the first node on the communication link is 80%, and the computation latency is 5 milliseconds. The CPU utilization of the tenth node on the communication link is 60%, and the computation latency is 15 milliseconds. The CPU utilization of the eighteenth node on the communication link is 60%, and the computation latency is 8 milliseconds. It can be determined that the first, tenth, and eighteenth nodes on the communication link all have abnormal indicator data.

[0075] The above technical solution, by acquiring the number of times each communication link is monitored during the historical operating period and the monitoring parameters of the communication link at each monitoring time, and determining the abnormal indicator data of each communication link based on the monitoring parameters of each communication link and the preset parameter range, can effectively identify the abnormal indicator data of the communication link and provide a basis for subsequently determining the confidence upper limit value.

[0076] Figure 5 It is based on Figure 3 The flowchart of another communication link monitoring method shown in the embodiment is as follows: Figure 5 As shown, Figure 3 As described in S2, determining the upper confidence limit of each communication link based on the abnormal indicator data of the communication link may include: S21, determine the total number of monitoring times based on the number of monitoring times for each of the communication links.

[0077] In this step, the sum of the number of monitoring times for each communication link is taken as the total number of monitoring times.

[0078] S22, determine the target number of abnormality data occurrences for each communication link.

[0079] In this step, if abnormal indicator data is found in the communication link during the monitoring process within the historical time period, it can be determined that the communication link has experienced an anomaly. Based on the number of times the communication link has experienced anomalies, the target number of anomalies is determined.

[0080] S23, the confidence upper limit of the communication link is determined by the total number of monitoring times based on the number of monitoring times of the communication link and the number of target anomalies.

[0081] The upper confidence bound (UCB) value is determined based on the number of monitoring cycles of the communication link and the number of target anomalies, as well as the total number of monitoring cycles.

[0082] In this step, for each communication link, the average anomaly probability of the communication link can be determined by dividing the number of target anomalies by the number of times the communication link is monitored. The exploration term for the communication link can be determined based on the total number of monitoring times, the number of times the communication link is monitored, and a preset adjustment parameter. The upper confidence limit value of the communication link is the sum of the average anomaly probability of the communication link and the exploration term of the communication link.

[0083] For example, the formula for calculating the upper confidence limit of the communication link is as follows:

[0084] In the above formula, UCB represents the upper confidence limit of the communication link, and the... The average anomaly probability of the communication link is represented by the following: These are the preset adjustment parameters. This is the total number of observations. This is the number of times link i was monitored.

[0085] The above technical solution determines the upper confidence limit of the communication link based on the number of monitoring times for each communication link and the number of target anomalies, and the total number of monitoring times. This enables dynamic selection and evaluation of the communication link, providing a basis for subsequently determining the current link level of the communication link.

[0086] Figure 6 It is based on Figure 3 The illustrated embodiment shows a flowchart of another communication link monitoring method, wherein the communication link includes at least one node, such as... Figure 6 As shown, Figure 3 Determining the current link level corresponding to the communication link based on the upper confidence limit of the communication link as described in S3 may include: S31, if the confidence upper limit is greater than the preset confidence upper limit threshold, obtain the number of nodes in the communication link.

[0087] In this step, by comparing the upper confidence limit of the communication link with a preset upper confidence limit threshold, if the upper confidence limit is greater than the preset upper confidence limit threshold, it can be considered that the communication link is abnormal, and the number of nodes in the communication link is obtained.

[0088] S32, if the number of nodes is greater than a preset node number threshold, determine the abnormal node in the communication link from the at least one node.

[0089] In this step, during the monitoring process, the monitoring parameters of each node in the communication link are monitored. If the monitoring parameters of a node exceed a preset parameter range, the node can be considered an abnormal node. Furthermore, if the number of nodes exceeds a preset node number threshold, the abnormal nodes in the communication link are identified from among the multiple nodes.

[0090] S33, the communication link is divided into abnormal sub-links and non-abnormal sub-links according to the abnormal node.

[0091] In one implementation, dividing the communication link into abnormal sub-links and non-abnormal sub-links based on the abnormal nodes may include: if it is determined that there are multiple intermittent abnormal nodes in the communication link, splitting the communication link into continuous abnormal sub-links and non-abnormal sub-links that include all abnormal nodes.

[0092] In another implementation, dividing the communication link into abnormal sub-links and non-abnormal sub-links based on the abnormal nodes may include: if it is determined that there are multiple consecutive abnormal nodes in the communication link, splitting the communication link into abnormal sub-links and non-abnormal sub-links that include the multiple consecutive abnormal nodes.

[0093] S34, determine the current link level of the abnormal sub-link as the first level, and determine the current link level of the non-abnormal sub-link as the second level.

[0094] The attention level corresponding to the first level is greater than that corresponding to the second level.

[0095] Optionally, if the number of nodes is less than or equal to a preset node number threshold, the target confidence upper limit value range to which the confidence upper limit value of the communication link belongs is determined.

[0096] The link level corresponding to the target confidence upper limit range is taken as the current link level of the communication link.

[0097] The above technical solution, based on the upper confidence limit of the communication link, the number of nodes, and the abnormal nodes existing in the communication link, divides the communication link into abnormal sub-links and non-abnormal sub-links, and classifies the abnormal sub-links and non-abnormal sub-links, which can locate abnormal nodes more quickly, thereby effectively improving the efficiency and accuracy of problem backtracking, and also providing a basis for dynamically determining the links to be monitored in the future.

[0098] Figure 7 It is based on Figure 3 The flowchart of another communication link monitoring method shown in the embodiment is as follows: Figure 7 As shown, Figure 3 The method described in S3 for determining the current link level corresponding to the communication link based on the upper confidence limit of the communication link may further include: S35, if the upper confidence limit of the communication link is less than or equal to a preset upper confidence limit threshold, determine the target upper confidence limit range to which the upper confidence limit of the communication link belongs.

[0099] In this step, multiple preset confidence upper limit value ranges are obtained, and the target confidence upper limit value range is determined based on the confidence upper limit value of the communication link.

[0100] S36, the link level corresponding to the target confidence upper limit range is taken as the current link level of the communication link.

[0101] In this step, different confidence upper limit value ranges correspond to different link level identifiers, and the link level corresponding to the target confidence upper limit value range can be used as the current link level of the communication link.

[0102] The above technical solution determines the current link level of the communication link by using the upper confidence limit of the communication link and the target upper confidence limit range to which the upper confidence limit of the communication link belongs. This can effectively identify and handle abnormal links, and also provide a basis for determining the links to be monitored based on the current link level and monitoring level identifier of the communication link, effectively improving the flexibility and scalability of communication link monitoring.

[0103] Figure 8 It is based on Figure 3 The flowchart of another communication link monitoring method shown in the embodiment is as follows: Figure 8 As shown, Figure 3 The generation of the preset configuration file based on the current link level as described in S4 may include: S41, for each communication link, obtain the initial configuration file of the communication link and the level identifier corresponding to the current link level of the communication link.

[0104] In this step, each communication link has an initial configuration file, which typically contains the link data for that communication link. The initial configuration file for the communication link and the level identifier corresponding to the current link level of that communication link are obtained.

[0105] S42, Generate the field value of the link level field based on the level identifier.

[0106] In this step, the link level field can be a string or an integer, used to represent the current level of the link, and the field value of the link level field is generated based on the current link level.

[0107] For example, PATH_LEVEL_RELEASE=0; PATH_LEVEL_PRO=1; PATH_LEVEL_MAX=2; PATH_LEVEL_DEVELOP=3. The link-level fields are PATH_LEVEL_RELEASE, PATH_LEVEL_PRO, PATH_LEVEL_MAX, and PATH_LEVEL_DEVELOP, and their values ​​are 0, 1, 2, and 3, respectively.

[0108] S43, add the link-level field and the field value of the link-level field to the initial configuration file to obtain the preset configuration file.

[0109] In this step, the initial configuration file for each communication link is read from the file system, a link-level field and its corresponding field value are added to the initial configuration file, and the modified configuration file is saved as a preset configuration file.

[0110] The above technical solution, by modifying the initial configuration file of the communication link and adding link-level information to obtain the preset configuration file, can provide a basis for subsequently determining the link-level identifier of the communication link from the preset configuration file and dynamically determining the link to be monitored based on the link-level identifier. This enables better utilization of link-level data and effectively improves the flexibility and scalability of communication link monitoring.

[0111] Figure 9 It is based on Figure 1 The flowchart of another communication link monitoring method shown in the embodiment is as follows: Figure 9 As shown, Figure 1 Step 103, which involves determining that the communication link belongs to the link to be monitored based on the link level identifier and the monitoring level identifier of the communication link, may include: Step 1031: Determine the first level of attention corresponding to the link level identifier and the second level of attention corresponding to the monitoring level identifier.

[0112] The link level identifier is used to characterize the level of attention of the communication link, and the monitoring level identifier can be used to characterize the level of attention of the communication link, and can be represented by numbers (such as 0, 1, 2) or characters (such as A, B, C).

[0113] Step 1032: If the first level of attention is less than or equal to the second level of attention, determine that the communication link belongs to the link to be monitored.

[0114] For example, the first attention level corresponding to the link level identifier of the first communication link is 1, the first attention level corresponding to the link level identifier of the second communication link is 0, the second attention level corresponding to the monitoring level identifier of the first communication link is 0, and the second attention level corresponding to the monitoring level identifier of the second communication link is 1. For the first communication link, since the first attention level of 1 is greater than the second attention level of 0, it can be determined that the first communication link is a non-monitored link. For the second communication link, since the first attention level of 0 is less than the second attention level of 1, it can be determined that the second communication link is a link to be monitored.

[0115] It should be noted that the number of communication links varies among different vehicle models, with vehicles in the R&D phase having more communication links than those in the mass production phase. Different vehicle models also have different monitoring level identifiers, with the monitoring level identifiers for vehicles in the R&D phase receiving higher attention than those for vehicles in the mass production phase. If the link level identifier of a third communication link is higher than its monitoring level identifier (meaning the link level identifier of the third communication link receives more attention than its monitoring level identifier), it may be impossible to monitor the third communication link because it is not present in that particular vehicle model.

[0116] The above technical solution determines the monitoring link based on the link-level identifier and the monitoring-level identifier. It can better utilize relevant link-level data to dynamically determine the monitoring link, thereby effectively improving the flexibility and scalability of communication link monitoring, and thus effectively improving vehicle safety and reliability.

[0117] Figure 10 It is based on Figure 1 The flowchart of another communication link monitoring method shown in the embodiment is as follows: Figure 10 As shown, Figure 1 Step 102, which involves determining the monitoring level identifier for each communication link, may include: Step 1021: Obtain the vehicle model information corresponding to the vehicle.

[0118] In this step, the unique identifier of the vehicle (such as vehicle ID) is obtained, and the vehicle model information of the current vehicle is determined based on the unique identifier of the vehicle.

[0119] Step 1022: Determine the monitoring level identifier of each communication link from the preset correspondence data based on the vehicle model information.

[0120] The corresponding relationship data includes the monitoring level identifier for each communication link corresponding to each vehicle model.

[0121] In this step, a data structure is predefined that contains the monitoring level identifier for each communication link corresponding to each vehicle model. Based on the vehicle model information, the monitoring level identifier for each communication link is retrieved from the corresponding relationship data.

[0122] The above technical solution determines the monitoring level identifier of each communication link based on the vehicle model information, providing a basis for dynamically determining the links to be monitored based on the link level identifier and monitoring level identifier of each communication link. This effectively improves the flexibility and scalability of communication link monitoring, thereby effectively enhancing vehicle safety and reliability.
