Detailed Description

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

A text generation method, an apparatus, an electronic device, and a storage medium of the embodiments of the present disclosure are described below with reference to the drawings.

In The related art, OTA (Over The Air Technology ) is widely used in an intelligent vehicle to solve The problem of upgrading an ECU or an MCU in The vehicle.

In general, the OTA is divided into full upgrade and differential upgrade modes. In the full-scale upgrading, the terminal needs to download all upgrading packages for upgrading, the consumed flow is large, the upgrading time is long, but the upgrading safety is high; the differential upgrading is also called incremental upgrading or patch upgrading, needs algorithm and tool support, only needs the terminal to download the differential upgrading package of the version to be upgraded and the existing version, and is high in upgrading efficiency.

However, when the upgrade fails, the upgrade failure result reported by the vehicle end cannot identify the upgrade type or the upgrade failure reason, and often a background worker is required to screen out a part related to the OTA upgrade from a large amount of logs reported by the vehicle end, and analyze the upgrade failure reason by combining the context code. In other words, some failure reasons of the vehicle-side full-scale upgrade or differential upgrade are general and cannot be obtained through machine screening, so that the failure reasons still need to be judged through a large amount of data pushed by the background in combination with the log, for example, for the differential upgrade, the failure reasons may be upgrade package errors, vehicle system abnormalities, upgrade version incompatibilities, system failures or human factors, and the like.

In order to solve the problems in the related art, an upgrade policy updating method, apparatus, electronic device and storage medium are provided in the present disclosure. The upgrade failure cases described in the present disclosure do not limit the upgrade types, and the differential upgrade and the upgrade failure cases thereof are taken as an embodiment in the present disclosure, which does not constitute a limitation of the present disclosure.

Fig. 1 is a schematic flowchart of an update policy updating method according to an embodiment of the present disclosure. The method can be applied to a terminal supporting OTA upgrade services, including but not limited to a vehicle, in particular a vehicle-mounted control system installed on the vehicle. In particular, the method can be applied to a controller supporting an OTA upgrade service in a terminal.

As shown in fig. 1, the method comprises the following steps:

step 101, responding to the upgrade failure of the terminal, and determining the marked data corresponding to the reason of the upgrade failure.

In an embodiment of the present disclosure, when the upgrade fails, the terminal controller may add the tag data of the upgrade result, respond to the upgrade failure result, analyze the upgrade failure result, and determine the failure reason and the tag data corresponding to the failure reason.

It is understood that the tag data corresponding to the failure reason refers to a field value that may reflect an upgrade type and/or a reason for the upgrade failure. The upgrade types comprise full upgrade and differential upgrade, and the upgrade failure reasons comprise but are not limited to upgrade package errors, vehicle machine system exceptions, upgrade version non-correspondence, system faults or human factors and the like, such as device node opening exceptions, signature information errors, timestamp errors and the like. For example, when the differential upgrade fails due to an upgrade packet error, the terminal controller may determine flag data corresponding to "differential upgrade" and "upgrade packet error" as "1".

It is understood that the tag data may be one field value or a plurality of field values, and is not limited in this disclosure.

And 102, sending the marked data to a cloud server so that the cloud server updates an upgrading strategy according to the marked data based on a preset updating strategy.

In an embodiment of the disclosure, the terminal may send the above-mentioned tag data to the cloud server in response to an upgrade failure. In the present disclosure, two ways for the terminal to send the tag data to the cloud server may be included.

In the first manner, generally, in the OTA upgrade interaction, the data reported by the terminal to the cloud generally has four fields, and in the disclosure, the terminal may add the tag data to the reported data, for example, the terminal may add a new field value to the format of the reported data to identify the upgrade type and the reason of the upgrade failure.

In a second manner, the terminal can report warning information to the cloud independently in response to the upgrade failure so as to inform the cloud server of the type and reason of the upgrade failure.

The manner in which the terminal sends the tag data to the cloud service is not limited in this disclosure.

After receiving the marked data, the cloud server can update the upgrade strategy configuration of the terminal according to the marked data based on a preset update strategy. In other words, the tag data may be used to assist the cloud server in updating the upgrade policy based on a preset update policy.

For example, the cloud server determines that the differential upgrade fails due to the error of the upgrade data packet of the terminal according to the received tag data "1", so that the upgrade strategy of the terminal is adjusted to be full upgrade.

And 103, receiving an updated upgrading strategy fed back by the cloud server.

In an embodiment of the present disclosure, the terminal may receive the updated upgrade policy from the cloud server.

In summary, according to the present disclosure, in response to a terminal upgrade failure, the terminal may determine tag data corresponding to a reason of the upgrade failure, and send the determined tag data to the cloud server, so that the cloud server updates an upgrade policy according to the tag data based on a preset update policy, and receives the updated upgrade policy, so that in an upgrade service, the terminal can automatically analyze the reason of the failure and report the reason to the cloud server, and the cloud server automatically matches the corresponding upgrade policy according to a corresponding upgrade type and the reason, thereby solving a problem that manual analysis is required and the upgrade policy configuration needs to be matched in a related art, and improving the reconfiguration and matching accuracy of the upgrade policy for the terminal with the upgrade failure.

Fig. 2 is a schematic flowchart of an update policy updating method according to an embodiment of the present disclosure. Fig. 2 is based on the embodiment shown in fig. 1, with further definitions of the

steps

101, 102. In the embodiment shown in fig. 2, step 101 may specifically include step 201 and step 202, and step 102 includes step 203 and step 204.

As shown in fig. 2, the method comprises the following steps:

step 201, responding to the upgrade failure of the terminal, and analyzing the reason of the upgrade failure.

In an embodiment of the present disclosure, the terminal controller may have an upgrade failure reason analysis capability, and the terminal responds to a failure result of its own differential upgrade and analyzes the differential upgrade failure result.

Step 202, according to the reason of the upgrade failure, the marked data corresponding to the reason of the upgrade failure is searched.

In an embodiment of the disclosure, after the terminal analyzes the differential upgrade failure result, the terminal may search for the upgrade type and the tag data corresponding to the reason of the upgrade failure. For example, a pre-configured corresponding relation table is stored in a local database of the terminal, and the terminal obtains the label data corresponding to the upgrade type and/or the upgrade failure reason by querying the corresponding relation table in the local database.

Step 203, the tag data is filled into the reported information.

In one embodiment of the present disclosure, the report information is the cloud data information reported by the terminal OTA, and the specific way of adding the tag data to the report information is to add a first field to the report data information; and writing the mark data into the first field, wherein the reported data further comprises a terminal identifier and a control module identifier of failed upgrade in the terminal.

It should be understood that, in the OTA service, the terminal generally reports data information to the cloud in a fixed data format, and the data reported by the terminal to the cloud generally has four fields. It is to be understood that the first field may be one field or a plurality of fields.

In an implementation manner of the present disclosure, the terminal may further add a field for identifying the terminal ID in the format of the reported data. For example, taking a vehicle as an example, a vin code of the vehicle is a vehicle ID, when the cloud pushes a differential upgrade package to the vehicle to perform differential upgrade, if a certain controller of the vehicle fails in differential upgrade, the vehicle reports information such as the vehicle ID, a result of the upgrade failure, and which controller fails in the upgrade (for example, an identifier of the controller) to the cloud, and the cloud searches for upgrade data corresponding to the vehicle in the background.

In other words, the purpose of including the terminal identifier in the terminal reported information is to facilitate the cloud server to search for the corresponding upgrade policy, update the upgrade policy, and send the updated upgrade policy to the terminal corresponding to the upgrade policy.

In an implementation manner of the present disclosure, since there may be multiple electronic control modules in the same terminal and there may be different upgrading requirements in the multiple electronic control modules, the cloud end will formulate a corresponding upgrading policy according to the data reported by the terminal.

And step 204, sending the reported information to a cloud server so that the cloud server updates an upgrading strategy according to the marked data.

In an embodiment of the disclosure, the terminal controller sends the data information to the cloud server, so that the cloud server can update a corresponding upgrading strategy for the control module which fails in upgrading according to the marking data.

In summary, in the present disclosure, the reason for the upgrade failure is analyzed in response to the upgrade failure of the terminal, the tag data corresponding to the reason for the upgrade failure is searched according to the reason for the upgrade failure, the tag data is filled into the report information, and the report information is sent to the cloud server, so that the cloud server updates the upgrade policy according to the tag data. The terminal which fails in upgrading can automatically analyze the failure reason and report the failure reason to the cloud server, and the cloud server automatically matches the corresponding upgrading strategy configuration, so that the problem that manual analysis and matching of the upgrading strategy configuration are needed in the prior art is solved, and the efficiency and matching accuracy of re-matching of the upgrading strategy configuration on the terminal which fails in upgrading are improved.

Fig. 3 is a schematic flowchart of an update policy updating method according to an embodiment of the present disclosure. The method is applied to the cloud server.

As shown in fig. 3, the method comprises the following steps:

step 301, receiving the label data corresponding to the reason of the upgrade failure of the terminal.

In an embodiment of the disclosure, a cloud server receives marked data corresponding to an upgrade failure reason sent by a terminal.

It should be understood that the tag data corresponding to the failure reason refers to a field value for identifying the upgrade type and/or the upgrade failure reason.

The upgrade type comprises full upgrade and differential upgrade, and the upgrade failure reasons include, but are not limited to, upgrade package errors, vehicle machine system exceptions, upgrade version inconsistency, system failures or human factors, and the like, for example, device node open exceptions, signature information errors, timestamp errors, and the like. For example, when the differential upgrade fails due to an upgrade data packet error, the terminal controller may determine that the flag data corresponding to the "differential upgrade" and the "upgrade data packet error" is "1", and the cloud server may receive the flag data and determine a specific upgrade type and a cause of the upgrade failure by comparing the flag data with each other.

And step 302, updating the upgrading strategy according to the marking data based on a preset updating strategy.

In an embodiment of the present disclosure, the cloud server updates the upgrade policy for the corresponding control module in the terminal corresponding to the cloud server according to the tag data, based on a preset update policy.

It should be understood that the preset update policy is preset in the cloud server, and there are corresponding update policies for different upgrade failure reasons, that is, a new scheme for configuring a suitable update policy for the control module in the terminal that fails to upgrade according to the upgrade failure reason is provided.

For example, the cloud server determines that the differential upgrade fails due to the error of the upgrade data packet of the terminal according to the received tag data, so that the upgrade strategy of the terminal is adjusted to be full upgrade.

For another example, the cloud server determines that the differential upgrade of the terminal fails due to the vehicle-mounted machine system failure according to the received tag data, and adjusts the upgrade strategy of the terminal to be the differential upgrade, but pushes a new differential upgrade package.

And step 303, sending the updated upgrading strategy to the terminal.

In an embodiment of the present disclosure, the cloud server sends the updated upgrade policy to its corresponding terminal.

In summary, the present disclosure receives the marked data corresponding to the reason for the failed upgrade of the terminal; updating the upgrading strategy according to the marking data based on a preset updating strategy; and sending the upgrading strategy to the terminal. The terminal which fails in upgrading can automatically analyze the failure reason and report the failure reason to the cloud server, and the cloud server automatically matches the corresponding upgrading strategy configuration, so that the problems that manual analysis is needed and the upgrading strategy configuration needs to be matched in the prior art are solved, and the efficiency and the matching accuracy of re-matching the upgrading strategy configuration for the terminal which fails in upgrading are improved.

Fig. 4 is a schematic flowchart of an update policy updating method according to an embodiment of the present disclosure. Fig. 4 is based on the embodiment shown in fig. 3, further defining the steps 301, 302. In the embodiment shown in fig. 4, step 301 may specifically include step 401 and step 402, and step 302 includes step 403.

As shown in fig. 4, the method comprises the following steps:

step 401, receiving the report information sent by the terminal.

In an embodiment of the present disclosure, the cloud server receives report information sent by the terminal, where the report information is data information reported to the cloud by the terminal OTA, and includes tag data corresponding to an upgrade failure reason.

Step 402, analyzing the reported information to obtain a first field, wherein the first field is filled with the tag data. The reported information also includes terminal identification and/or identification of control module in terminal which is failed to upgrade.

In some embodiments of the disclosure, after the cloud server analyzes the report information sent by the terminal, a first field may be obtained, and the tag data is filled in the first field. The cloud server can also obtain the terminal identification and/or the control module identification failed in the terminal through analysis.

And 403, configuring an upgrading strategy for the terminal according to the marked data based on the terminal identifier and the identifier of the control module which fails to be upgraded in the terminal, wherein the upgrading strategy is used for upgrading all the control modules which fail to be upgraded in the terminal again.

In an embodiment of the present disclosure, the cloud server configures, based on a preset update policy, an upgrade failure electronic control module according to the terminal identifier and the terminal, and configures an upgrade policy for the terminal according to the tag data, where the upgrade policy is used for upgrading all upgrade failure control modules in the terminal again.

In the embodiment of the present disclosure, the one upgrade failure reason matches one sub-upgrade policy, and one upgrade policy matches at least one terminal. In other words, the updating strategy of the terminal can be updated according to the respective failure reasons of a plurality of electronic control modules with failed upgrade in the same terminal, wherein the updated updating strategy can comprise configuring a full upgrade strategy for a part of the electronic control modules and configuring a differential upgrade strategy for the other part of the electronic control modules. Optionally, the updated upgrade strategy may also be an upgrade strategy according to each module, which is integrated into a whole vehicle upgrade strategy, where the range of the whole vehicle upgrade strategy is the maximum range of the upgrade strategy of each module. For example, the updating strategy for a certain terminal may be to configure a differential updating strategy for A, B, C, configure a full updating strategy for D, E, or adopt a full updating strategy for all five a-E electronic control modules.

Further, the specific update scheme of the upgrade policy configuration is as follows:

and if the upgrade failure reasons of all the control modules with the upgrade failure in the terminal are errors of the differential upgrade package, configuring the upgrade strategy into full upgrade.

If the upgrade failure reason of the control module with the first part of upgrade failure in the terminal is irrelevant to the differential upgrade package, the upgrade strategy is configured to perform differential upgrade on the control module with the first part of upgrade failure, and perform full upgrade on the rest control modules with the upgrade failure.

It should be understood that, for the failure reason of the electronic control module that fails to be upgraded, if the failure reason is not related to the differential upgrade policy, the differential upgrade policy is continuously pushed, and at this time, other factors may be eliminated, and the differential upgrade is performed again, so that the upgrade is successful; and if the upgrade failure reason is caused by errors of the differential upgrade package, pushing a full-scale upgrade strategy.

For example, the reason for the failure of the differential upgrade obtained by the analysis is disconnection of the terminal network, and at this time, the differential upgrade strategy can still be adopted.

In an embodiment of the present disclosure, the cloud server updates the upgrade policy and sends the upgrade policy to the corresponding terminal.

In summary, the present disclosure receives the report information sent by the terminal; analyzing the reported information to obtain a first field, wherein the first field is filled with the marking data, and a terminal identifier in the reported information and a control module identifier of failed upgrade in the terminal are obtained; based on the terminal identification and the control module identification which fails to be upgraded in the terminal, configuring an upgrading strategy for the terminal according to the marked data, wherein the upgrading strategy is used for upgrading all the control modules which fail to be upgraded in the terminal again; and sending the upgrading strategy to the terminal. The terminal which fails in upgrading can automatically analyze the failure reason and report the failure reason to the cloud server, and the cloud server automatically matches the corresponding upgrading strategy configuration, so that the problems that manual analysis is needed and the upgrading strategy configuration needs to be matched in the prior art are solved, and the efficiency and the matching accuracy of re-matching the upgrading strategy configuration for the terminal which fails in upgrading are improved.

In some embodiments of the present disclosure, taking the failure of the vehicle differential upgrade as an example, the upgrade policy updating method may be performed according to the following full flow.

1. And adding mark data of the differential upgrade result in a terminal controller, wherein the controller supporting the differential upgrade of the terminal can add an upgrade result mark for distinguishing the full scale from the differential scale in the differential implementation.

2. And the terminal OTA module adds the mark content of the differential upgrade failure in the data content reported to the cloud, wherein the field record of the failure reason is added in the reported data format of the OTA service, and the mark of the differential upgrade failure can be filled in the reported data content. For example, in a general case, the vehicle-side OTA module has four fields in the data information reported to the cloud, and one field value may be added to identify the reason for the differential failure. In this way, a field is added to the original reported data, so that the matching and modification degree of the system is minimum. Of course, the terminal may send the marked content to the cloud in other manners, such as reporting warning information separately for informing the cloud of the reason for the upgrade failure, which is not limited herein. The reasons for failure may include: the execution start device node opens an exception, that is, a system function exception is detected during the running process of the program, or a signature information error, or a time stamp error, etc., which are not listed herein.

3. And the cloud OTA system automatically processes the failed differential upgrade failure information, wherein for the vehicle information failed in differential upgrade, the OTA background can perform screening and identification through the reported data, and the vehicle information failed in differential upgrade is filtered according to the identified failure reason field content. It can be understood that there is vehicle information in the four fields reported by the terminal controller, that is, the vin code of the vehicle itself, which can be understood as the vehicle ID, and after the cloud server pushes the differential upgrade task to the vehicle, if the controller supporting the differential upgrade service in the vehicle fails to be upgraded, the vehicle will report the vin code, the result of the failed upgrade, and the controller ID of the failed upgrade to the cloud.

4. The cloud OTA system automatically generates vehicle processing strategy configuration of failure differential upgrading, wherein the cloud OTA analyzes specific controller information of failure according to the identified differential upgrading vehicle information, and then generates strategy configuration for performing full upgrading on the controller in the background. For example, if the reason for the failure of the upgrade is that the base version of the vehicle is inconsistent with the version stored in the cloud, the cloud will not push the differential upgrade package to the vehicle for differential upgrade, but update the differential upgrade package to the full upgrade policy, and push the full upgrade package. For another example, if the upgrade data packet has no problem and the reason for the upgrade failure is that a certain module is abnormal in the operation process of the vehicle end, the cloud end may still adopt a differential upgrade strategy to push a new differential upgrade data packet.

5. The cloud OTA system automatically matches the vehicle information to corresponding strategy configuration, wherein the cloud OTA system matches a corresponding full-scale upgrading strategy according to the differential upgrading failure vehicle information identified by monitoring, and then automatic matching and importing of the vehicle information are carried out.

It is understood that in the present disclosure, one failure cause may match one policy, and one policy may match multiple vehicles. For example, from the perspective of the cloud server, 500 vehicles adopt the upgrade policy 1 by default, and after ten vehicles fail to be upgraded, the background process is how to reissue the data packets to the vehicle. For example, five of the vehicles may be re-matched to upgrade policy 2. For a vehicle, a failure to upgrade a vehicle may consist of multiple controller failures, for which the updated upgrade strategy may have multiple options. According to the reasons of upgrade failure of all the controllers, the whole vehicle upgrade strategy is updated, for example, five controllers should match the upgrade strategy as differential upgrade, and other controllers should match as full upgrade, and then the whole vehicle upgrade strategy is full upgrade, or the updated whole vehicle strategy may be a combination strategy, for example, the upgrade strategies of five controllers are matched as differential upgrade, and other controllers are matched as full upgrade.

Corresponding to the updating method of the upgrading strategy, the invention also provides an updating device of the upgrading strategy. Since the device embodiment of the present invention corresponds to the method embodiment described above, details that are not disclosed in the device embodiment may refer to the method embodiment described above, and are not described again in the present invention.

Further, the step of filling the tag data into the report information includes: adding a first field in the reported information; and writing the marking data into the first field, wherein the reported data further comprises a terminal identifier and a control module identifier of failed upgrade in the terminal.
