[0002] Currently, with the development of the current vehicle networking technology, the functions and complexity of vehicles are getting higher and higher, and there are more and more ECUs (Electronic Control Units) installed on vehicles.

Through OTA (Over-The-Air Technology), the vehicle ECUs can be remotely upgraded, which can continuously improve the terminal functions and services of the vehicle and enable the vehicle owner to have a more convenient and intelligent vehicle use experience.

[0003] In the prior art, for automotive OTA remote upgrade, the host factory deploys tasks on the OTA cloud server side and pushes the upgrade tasks to the automotive OTA main controller.

[0049] The following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] Figure 1 It is a flowchart of a vehicle upgrade method provided by an embodiment of the present application. Figure 1 The shown vehicle upgrade method is applied to Figure 2 the cloud management platform in Figure 2 It is a schematic diagram of an application scenario of the vehicle upgrade method provided by the present application. As Figure 2 shown, the cloud management platform and the vehicle terminal are communicatively connected. The vehicle terminal sends data information to the cloud, and the cloud management platform sends upgrade information and upgrade strategies to the vehicle terminal. The vehicle terminal upgrades the electronic control unit of the vehicle terminal based on the upgrade information and upgrade strategies.

[0051] Figure 1 The shown vehicle upgrade method is applied to Figure 2 the cloud management platform in Figure 1 As shown, the method may include the following steps:

[0052] Step 101: Obtain the data information reported by the vehicle, and determine multiple electronic control units to be upgraded according to the preset upgrade conditions.

[0053] Specifically, obtain the data information reported by the vehicle. The data information has been pre - processed through a series of data pre - processing operations. The data information uploaded by the vehicle contains the data information of the vehicle - end ECU (electronic control unit). According to the preset upgrade conditions, determine the ECUs in the vehicle - end ECU that meet the upgrade conditions to obtain multiple ECUs to be upgraded. The data information corresponding to the multiple electronic control units to be upgraded can be used as upgrade preparation data. Traverse the upgrade preparation data, and judge whether there is a differential package for each ECU to be upgraded. According to the judgment result, supplement attributes such as the upgrade package address and upgrade package size to the upgrade preparation data.

[0054] Step 102: Obtain the upgrade operation information of each electronic control unit to be upgraded, and determine multiple upgrade strategies according to the upgrade operation information, where the multiple upgrade strategies represent the combination method of the multiple electronic control units during the upgrade.

[0055] Specifically, obtain the upgrade operation information of each electronic control unit to be upgraded. The upgrade operation information includes the upgrade duration, upgrade sequence, and upgrade logic relationship. Among them, the upgrade logic relationship includes the parallel upgrade relationship and mutual exclusion upgrade relationship between each ECU. According to the parallel upgrade relationship and mutual exclusion upgrade relationship, manage multiple ECUs according to the upgrade mutual exclusion group and parallel group, and place the ECUs that can be upgraded simultaneously into the same parallel group to obtain multiple upgrade strategies. Among them, the multiple upgrade strategies represent the combination methods of the multiple electronic control units during the upgrade.

[0056] For example, the four electronic control units are A, B, C, and D respectively. According to the upgrade operation information of each electronic control unit, it is determined that A and B are mutually exclusive and cannot be parallel. Then the following four upgrade strategies can be generated:

[0057] (1) AC in the same group, BD in the same group;

[0058] (2) ACD in the same group, B in one group;

[0059] (3) AD in the same group, BC in the same group;

[0060] (4) A in one group, BCD in the same group.

[0061] Step 103: Determine the target upgrade strategy with the shortest upgrade duration among the multiple upgrade strategies.

[0062] Specifically, in step 102, multiple combination methods of multiple electronic control units during the upgrade that satisfy the execution logic relationship between multiple ECUs are determined. Place the ECUs that can be upgraded simultaneously into the same parallel group according to the principle of the shortest time, and calculate the total estimated upgrade time after grouping. Based on the principle of the minimum time, determine the target upgrade strategy with the shortest total upgrade duration among the multiple upgrade strategies.

[0063] For example, the four electronic control units are A, B, C, and D respectively, and the upgrade durations are A = 10 minutes, B = 15 minutes, C = 11 minutes, and D = 12 minutes respectively. According to the upgrade operation information of each electronic control unit, it is determined that A and B are mutually exclusive and cannot be parallel. Then the following four upgrade strategies can be generated:

[0064] (1) AC in the same group, BD in the same group;

[0065] (2) ACD in the same group, B in one group;

[0066] (3) AD in the same group, BC in the same group;

[0067] (4) A in one group, BCD in the same group.

[0068] After grouping, calculate the total upgrade time respectively as:

[0069] (1) 11 + 15 = 26 minutes;

[0070] (2) 12 + 15 = 27 minutes;

[0071] (3) 12 + 15 = 27 minutes;

[0072] (4) 10 + 15 = 25 minutes.

[0073] Therefore, the upgrade strategy of Group A and Groups B, C, and D in the same group is the upgrade strategy with the shortest total upgrade duration, and the upgrade strategy of the (4)th group is used as the target upgrade strategy.

[0074] Step 104: Send the upgrade information of the multiple electronic control units and the target upgrade strategy to the vehicle end.

[0075] Specifically, the upgrade information of the multiple electronic control units is the upgrade package corresponding to the upgrade of each ECU that needs to be upgraded. The target upgrade strategy includes the upgrade strategy determined based on the principle of minimum time when performing the upgrades of multiple ECUs and the estimated upgrade time. The calculated information such as the estimated upgrade time and the total size of the upgrade packages is supplemented to the upgrade preparation data, and the assembled data is sent to the vehicle end. For some upgrades, differential packages can be sent to save traffic.

[0076] It can be seen that in the embodiment of the present application, by obtaining the data information reported by the vehicle, according to the preset upgrade conditions, multiple electronic control units that need to be upgraded are determined; the upgrade operation information of each electronic control unit that needs to be upgraded is obtained, and multiple upgrade strategies are determined according to the upgrade operation information. Further, the target upgrade strategy with the shortest upgrade duration among the multiple upgrade strategies is determined, and the upgrade information of the multiple electronic control units and the target upgrade strategy are sent to the vehicle end. On the one hand, in the cloud, according to the preset upgrade conditions, multiple electronic control units that need to be upgraded are determined, and the upgrade information of the multiple electronic control units that need to be upgraded is sent to the vehicle end. By making a preliminary judgment based on the upgrade conditions in the cloud, it is not necessary to send all the upgrade data to the vehicle end, which saves traffic, improves security, and saves the computing resources of the vehicle end. On the other hand, by determining multiple upgrade strategies in the cloud and sending the target upgrade strategy with the shortest upgrade duration to the vehicle end, the upgrade efficiency can be improved. The present application can save traffic, save the computing resources of the vehicle end, and improve the security and efficiency of vehicle upgrades.

[0077] In one embodiment of the present application, obtaining the upgrade operation information of each electronic control unit to be upgraded in step 102 and determining multiple upgrade strategies according to the upgrade operation information includes: determining the running logic relationship between each electronic control unit according to the upgrade operation information; determining multiple first electronic control units according to the running logic relationship, wherein the first electronic control units can be upgraded in parallel; determining multiple upgrade strategies according to the multiple first electronic control units, wherein the multiple upgrade strategies represent the combination modes for upgrading the multiple first electronic control units in parallel.

[0078] Specifically, obtain the upgrade operation information of each electronic control unit to be upgraded. The upgrade operation information includes upgrade duration, upgrade sequence, and upgrade running logic relationship. The upgrade logic relationship includes the parallel upgrade relationship and mutual exclusion upgrade relationship between each ECU. According to the parallel upgrade relationship and mutual exclusion upgrade relationship, manage multiple ECUs according to upgrade mutual exclusion groups and parallel groups, and place the ECUs that can be upgraded simultaneously into the same parallel group to obtain multiple upgrade strategies, where the multiple upgrade strategies represent the combination modes of the multiple electronic control units during upgrade.

[0079] For example, the four electronic control units are A, B, C, and D respectively. According to the upgrade operation information of each electronic control unit, it is determined that A and B are mutually exclusive and cannot be upgraded in parallel. Then the following four upgrade strategies can be generated:

[0080] (1) A and C are in the same group, B and D are in the same group;

[0081] (2) A, C, and D are in the same group, B is in a separate group;

[0082] (3) A and D are in the same group, B and C are in the same group;

[0083] (4) A is in a separate group, B, C, and D are in the same group.

[0084] In one embodiment of the present application, determining the target upgrade strategy with the shortest upgrade duration among the multiple upgrade strategies in step 103 includes: determining the first duration required for each electronic control unit to be upgraded according to the upgrade operation information; calculating the second duration required for each upgrade strategy among the multiple upgrade strategies according to the first duration; determining the upgrade strategy with the shortest second duration as the target upgrade strategy.

[0085] Specifically, in step 102, multiple combination modes of multiple electronic control units during upgrade that satisfy the execution logic relationship between them are determined. Place the ECUs that can be upgraded simultaneously into the same parallel group according to the principle of the shortest time, and calculate the total estimated upgrade time after grouping. Based on the principle of the minimum time, determine the target upgrade strategy with the shortest total upgrade duration among the multiple upgrade strategies.

[0086] For example, the four electronic control units are A, B, C, and D respectively. The first time required for each electronic control unit to be upgraded is A = 10 minutes, B = 15 minutes, C = 11 minutes, and D = 12 minutes. According to the upgrade operation information of each electronic control unit, it is determined that A and B are mutually exclusive and cannot be parallel. Then four upgrade strategies can be generated:

[0087] (1) AC are in the same group, and BD are in the same group;

[0088] (2) ACD are in the same group, and B is in a separate group;

[0089] (3) AD are in the same group, and BC are in the same group;

[0090] (4) A is in a separate group, and BCD are in the same group.

[0091] After grouping, according to the first time, calculate the second time required for each upgrade strategy among the multiple upgrade strategies as follows:

[0092] (1) 11 + 15 = 26 minutes;

[0093] (2) 12 + 15 = 27 minutes;

[0094] (3) 12 + 15 = 27 minutes;

[0095] (4) 10 + 15 = 25 minutes.

[0096] Therefore, the upgrade strategy with A in a separate group and BCD in the same group is the upgrade strategy with the shortest total upgrade time, and the upgrade strategy of the (4)th group is taken as the target upgrade strategy.

[0097] In an embodiment of the present application, before step 101 obtains the data information reported by the vehicle and determines the multiple electronic control units that need to be upgraded according to the preset upgrade conditions, it further includes: determining whether there is an ongoing upgrade task for the vehicle. If there is no ongoing upgrade task for the vehicle, then determine the target upgrade task according to the attribute information of the vehicle; obtain the vehicle identification number of the vehicle, and determine whether the vehicle identification number is in the blacklist of the target upgrade task. If the vehicle identification number is not in the blacklist of the target upgrade task, then send a data acquisition instruction to the vehicle.

[0098] Specifically, according to vehicle attributes such as vehicle identification number, vehicle label, vehicle location, vehicle real-name status, etc., determine the upgrade activities to be issued. Determine whether there is an in-progress upgrade task for the vehicle. If there is no in-progress upgrade task for the vehicle, determine the target upgrade task according to the vehicle's attribute information. Determine whether there is an in-progress task for the vehicle reporting data, including the following process: First, the vehicle checks for the new version, and the cloud consumes kafka information in sequence. Second, determine whether there is an in-progress task for the current vehicle. If there is no in-progress task for the current vehicle, the process ends. If there is an in-progress task for the current vehicle, determine whether the activity corresponding to the task is within the validity period. If the activity is not within the validity period, modify the current background status to activity expired and end the process. If the activity corresponding to the task is within the validity period, further determine whether the upgrade task status is in the pending start state. If the result is yes, resend the current task to the vehicle terminal and end the process. If the result of whether the upgrade task status is in the pending start state is no, push the data that does not meet the upgrade to the vehicle terminal through kafka and end the process. If there is no in-progress task, preprocess the data reported by the vehicle, specifically including: Preprocessing the vehicle data requires unique calibration of the ECU, querying the special ECU list cache, comparing all ECUs reported by the vehicle, and marking the special ECUs, the revised version numbers, and the version numbers of all ECUs.

[0099] Obtain the vehicle identification number of the vehicle, and determine whether the vehicle identification number is in the blacklist of the target upgrade task. If the vehicle identification number is not in the blacklist of the target upgrade task, send a data acquisition instruction to the vehicle. In this step, perform a dependency check on the upgrade activity, which requires checking whether the VIN code of the current vehicle exists in the blacklist of the current service. The vehicle VIN code is the abbreviation of Vehicle Identification Number, also known as the vehicle identification number or vehicle identification code. If the identification code of the vehicle does not exist in the blacklist, the activity task can be executed. If the identification code of the vehicle exists in the blacklist, the activity task is not executed.

[0100] Specifically, the activity dependency check also includes other check methods, such as whether the static label dependency passes, whether the dynamic label dependency passes, and whether the device dependency permission passes. If any one does not pass, the activity task is not executed.

[0101] Among them, the static label dependency check includes checking whether the set of activity vehicles contains the VIN code of the current vehicle.

[0102] Dynamic label dependency verification needs to sequentially determine whether there is a vehicle activation status dependency, whether there is a real-name status dependency, and whether there is a vehicle location dependency. When determining whether there is a vehicle activation status dependency, it is possible to further determine whether the current vehicle activation status is consistent with the activity dependency. When determining whether there is a real-name status dependency, it is possible to further determine whether the real-name status of the VIN is consistent with the activity dependency. When determining whether there is a vehicle location dependency, it is possible to further determine whether the city where the current VIN is located is within the city of the activity dependency.

[0103] Device dependency permission verification needs to determine whether the ECU of the activity dependency exists in the current vehicle, and further needs to determine whether the current ECU is a special ECU. If the current ECU is a special ECU, then it depends on whether the first value of the revision number and the first value of the vehicle ECU revision number are the same. Calculate the numerical value through the version number, and compare the activity ECU and the vehicle ECU version number values according to rules such as greater than or less than. If the current ECU is not a special ECU, then calculate the numerical value through the logistics number, and further compare the activity ECU value and the vehicle ECU version number value according to rules such as greater than or less than. If the activity ECU value and the vehicle ECU version number value are inconsistent, it indicates that the ECU of the activity dependency is inconsistent with the ECU existing in the current vehicle, and the activity is not executed.

[0104] In an embodiment of the present application, obtaining the data information reported by the vehicle in step 101 and determining multiple electronic control units to be upgraded according to pre-set upgrade conditions includes: determining service software summary information according to the target upgrade task, where the service software summary information includes multiple target data required to execute the target upgrade task; determining upgrade preprocessing information according to the data information reported by the vehicle; traversing the service software summary information to determine whether the target data exists in the upgrade preprocessing data. If each piece of the target data exists in the upgrade preprocessing data, then determine multiple electronic control units to be upgraded according to pre-set upgrade conditions.

[0105] Specifically, the service software summary information required for the upgrade activity is determined in the cloud according to the target upgrade task, wherein the service software summary information includes multiple target data required to execute the target upgrade task. The upgrade preprocessing information is determined according to the data information reported by the vehicle, and the service software summary information is traversed to determine whether the target data exists in the upgrade preprocessing data. If each of the target data exists in the upgrade preprocessing data, multiple electronic control units that need to be upgraded are determined according to the preset upgrade conditions. Specifically, the list of ECUs that need to be upgraded in the upgrade service is traversed, and the vehicle is queried according to the combination of "ECU name + hardware part number + software part number + whether it is calibrated" to see whether the vehicle reports the same data, and the data that passes is initialized to the upgrade preprocessing data. The list of ECUs that need to be upgraded in the service is traversed, and duplicate data is removed according to ECU name + whether it is calibrated, and the deduplicated data is initialized to the service software summary information. The service software summary information is traversed to compare whether the data in the summary information exists in the upgrade preprocessing data. If all of them exist, the service can be upgraded, otherwise the verification fails.

[0106] The embodiments of the present application can verify whether the vehicle ECU data information required for the cloud upgrade task has been fully reported by the vehicle side, and confirm whether the data information of each ECU reported by the vehicle matches the data required for the upgrade activity, thereby improving the security and accuracy of the upgrade.

[0107] In one embodiment of the present application, the data information reported by the vehicle is obtained in step 101, and multiple electronic control units that need to be upgraded are determined according to pre-set upgrade conditions, including: obtaining the data information reported by the vehicle, the data information reported by the vehicle includes version number information of the vehicle-side electronic control unit; if the version number information of the vehicle-side electronic control unit meets the preset upgrade conditions, determining that the vehicle-side electronic control unit is an electronic control unit that needs to be upgraded.

[0108] Specifically, the data information reported by the vehicle is obtained, and the data information reported by the vehicle includes the version number information of the vehicle-side electronic control unit. The upgrade task is issued according to the vehicle attributes, such as the frame number, vehicle label, vehicle location, vehicle real-name status and other attributes. If the version number information of the vehicle-side electronic control unit meets the preset upgrade conditions, the vehicle-side electronic control unit is determined to be an electronic control unit that needs to be upgraded, that is, according to the device version number attribute, for example, an ECU greater than a specific version number can issue an upgrade task, and according to the version number reported by the vehicle's current ECU, it is determined whether the upgrade task of the corresponding activity can be issued.

[0109] In an embodiment of the present application, based on pre-set upgrade conditions in the cloud, multiple electronic control units (ECUs) that need to be upgraded are determined, and the upgrade information of the multiple ECUs that need to be upgraded is sent to the vehicle side. By making a preliminary judgment based on the upgrade conditions in the cloud, it is not necessary to send all upgrade data to the vehicle side, which saves traffic, improves security, and saves the computing resources of the vehicle side.

[0110] It can be seen that in an embodiment of the present application, by obtaining the data information reported by the vehicle and based on pre-set upgrade conditions, multiple ECUs that need to be upgraded are determined; the upgrade operation information of each ECU that needs to be upgraded is obtained, and multiple upgrade strategies are determined according to the upgrade operation information. Further, the target upgrade strategy with the shortest upgrade duration among the multiple upgrade strategies is determined, and the upgrade information of the multiple ECUs and the target upgrade strategy are sent to the vehicle side. On the one hand, in the cloud, based on pre-set upgrade conditions, multiple ECUs that need to be upgraded are determined, and the upgrade information of the multiple ECUs that need to be upgraded is sent to the vehicle side. By making a preliminary judgment based on the upgrade conditions in the cloud, it is not necessary to send all upgrade data to the vehicle side, which saves traffic, improves security, and saves the computing resources of the vehicle side. On the other hand, by determining multiple upgrade strategies in the cloud and sending the target upgrade strategy with the shortest upgrade duration to the vehicle side, the upgrade efficiency can be improved. The present application can save traffic, save the computing resources of the vehicle side, and improve the security and efficiency of vehicle upgrades.

[0111] Figure 3 A vehicle upgrade method as shown is applied to Figure 2 the vehicle side in Figure 3 As shown, the method may include the following steps:

[0112] Step 301: Send data information to the cloud management platform.

[0113] Specifically, data information is sent to the cloud management platform. The data information has undergone a series of data preprocessing operations. The data information uploaded by the vehicle contains the data information of the vehicle-side ECU (electronic control unit). Based on pre-set upgrade conditions, the ECUs in the vehicle-side ECU that meet the upgrade conditions are determined to obtain multiple ECUs that need to be upgraded. The data information corresponding to the multiple ECUs that need to be upgraded can be used as upgrade preparation data. By traversing the upgrade preparation data, it is judged whether there is a differential package for each ECU that needs to be upgraded, and attributes such as the upgrade package address and upgrade package size are supplemented to the upgrade preparation data according to the judgment result.

[0114] Step 302: Receive the upgrade information of multiple electronic control units and the target upgrade strategy sent by the cloud management platform, where the multiple electronic control units represent the electronic control units that need to be upgraded on the vehicle side, and the target upgrade strategy represents determining multiple upgrade strategies based on the upgrade operation information of each electronic control unit that needs to be upgraded, and determining the strategy with the shortest upgrade duration among the multiple upgrade strategies.

[0115] Specifically, the cloud determines multiple combination ways for the multiple electronic control units to be upgraded when satisfying the execution logic relationship between multiple ECUs. The ECUs that can be upgraded simultaneously are grouped into the same parallel group according to the principle of the shortest time, and the total estimated upgrade time is calculated after grouping. Based on the principle of the minimum time, the target upgrade strategy with the shortest total upgrade duration among the multiple upgrade strategies is determined. Receive the upgrade information of multiple electronic control units and the target upgrade strategy sent by the cloud management platform.
