Description
Technical Field

Background
With the popularity of networks and smart devices, more and more objects need to be updated frequently to meet the changing user needs and project needs. Currently, the mainstream object update method is Over-the-Air (OTA) technology, popular name remote upgrade, which transmits an upgraded version of an object or difference content (i.e. incremental content) between a current version and an upgraded version to an intelligent device through a network, so that the intelligent device updates the object.
Taking the internet of vehicles as an example, the vehicle control system, the vehicle-mounted application, and the like included in the vehicle are mostly updated by the OTA technology at present. In view of the fact that the versions of the car networking objects existing in the market at present are many and not uniform, and the difficulty in making incremental content is high, when the car networking objects are updated, a full-volume package mode of upgrading the versions is mostly adopted. Specifically, for the upgrade version, a full upgrade package covering all Electronic Control Units (ECUs) of the whole vehicle is directly generated, and then the vehicle downloads the full upgrade package to complete the upgrade of all ECUs in the vehicle. However, the content redundancy covered in the full upgrade package is too much, which not only wastes traffic, but also causes slow upgrade process and low upgrade efficiency.

Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be described in further detail below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The object upgrading method provided by the embodiment of the disclosure is mainly suitable for the situation of object remote upgrading based on the OTA technology, and is particularly suitable for the upgrading process of the objects in the Internet of vehicles. The object upgrading method provided by the embodiment of the present disclosure may be executed by an object upgrading apparatus, which may be implemented in software and/or hardware, and the apparatus may be integrated in an electronic device with higher data processing and storage functions, such as a notebook computer, a desktop computer, or a server.
Fig. 1 is a flowchart of an object upgrading method provided in an embodiment of the present disclosure. Referring to fig. 1, the object upgrading method specifically includes:
s110, an upgrade information query request sent by a client is received, wherein the upgrade information query request comprises the current version information of an object to be upgraded.
The object to be upgraded may be an application and/or software. In some embodiments, when the object is an object in a vehicle, the object includes an in-vehicle application, a vehicle system program, or an in-vehicle system program.
If the object in the client needs to be updated, the client uses the current version information of the object as a request parameter to generate an upgrade information query request and sends the upgrade information query request to a server where the object upgrade device is located. The upgrade information query request is used for requesting the information of the upgrade package adapted to the object from the server.
It should be noted that, because the data volume of the upgrade package is usually large, in the embodiment of the present disclosure, information of all upgrade packages, for example, unit upgrade package information, version upgrade package information corresponding to the version increment upgrade package, and the like, may be recorded, so that a suitable upgrade package is queried through the recorded information in the upgrade process, and the query efficiency of the upgrade package in the upgrade process is improved. The unit upgrade package refers to an upgrade package corresponding to a function module (i.e., a function program unit) in the smallest detachable unit of the object. In some embodiments, when the object to be upgraded is an object in a vehicle, the functional program unit is an electronic control unit ECU in the vehicle. In this embodiment, the upgrade package corresponding to 1 ECU is 1 unit upgrade package. The version increment upgrade package is a total upgrade package formed by all unit upgrade packages with differences (addition, deletion and change) in the object. In some embodiments, the upgrade package information includes at least one of identification of a corresponding upgrade package, content description information, encryption key information, and version information before and after upgrade. Preferably, the upgrade package information records multiple items of related information of the upgrade package, such as an upgrade package identifier, descriptive information of content in the upgrade package, encryption key information, version information before and after upgrade, and the like.
S120, determining at least one target unit upgrading packet corresponding to the object based on the current version information, the upgrading version information and the unit upgrading packet information corresponding to each unit upgrading packet.
Each unit upgrade package comprises a unit difference package or a unit total package generated by each functional program unit in each stock version compared with the upgraded version. The inventory version refers to the version of the object already existing in the market, which contains the current version.
In the object upgrading process, the difference of the two versions is compared in real time, and the process of generating the incremental upgrading package based on the difference consumes more time. In order to improve the object upgrade efficiency, in the embodiment of the present disclosure, a unit upgrade package is generated in advance for each functional program unit in each stock version. The unit upgrade package may be a unit differential package containing only version differential content, or may be a unit full package containing content corresponding to the corresponding functional program unit in the upgraded version. Therefore, after the server side acquires the current version information, at least one unit upgrading packet which is suitable for the current object can be directly determined from all the unit upgrading packets and is used as a target unit upgrading packet based on the current version information and the upgrading version information, and the process of comparing differences in real time and regenerating an increment upgrading packet is not needed.
Exemplarily, S120 includes: determining version difference information based on the current version information and the upgrade version information; and determining each target unit upgrading packet based on the version difference information and the unit upgrading packet information corresponding to each unit upgrading packet. And the server compares the difference between the current version corresponding to the current version information and the upgrade version corresponding to the upgrade version information, and determines the functional program units with the difference, namely determines the version difference information. And then, screening all the unit upgrading package information according to the information of the functional program units in the version difference information so as to screen a target unit upgrading package from all the unit upgrading packages. Therefore, the target unit upgrading package can be determined more flexibly and dynamically on the basis of ensuring less mutual information.
S130, generating a target version increment upgrading package corresponding to the object by each target unit upgrading package, and feeding back target version upgrading package information corresponding to the target version increment upgrading package to the client so that the client can finish upgrading the object based on the target version upgrading package information.
And the server side makes the determined target unit upgrade packages become target version increment upgrade packages, and records the information of the target version increment upgrade packages (namely the target version upgrade package information). And then, feeding back the target version upgrading packet information to the client.
In some embodiments, after the version upgrade information corresponding to the version increment upgrade package is fed back to the client, the method further includes: receiving an upgrade package acquisition request sent by a client, wherein the upgrade package acquisition request comprises target version upgrade package information; and feeding back the target version increment upgrading package to the client based on the target version upgrading package information. After receiving the target version upgrading package information, the client generates an upgrading package obtaining request based on the target version upgrading package information and sends the upgrading package obtaining request to the server, so that the server is requested to send the target version increment upgrading package to the client, and the client can complete the upgrading of the object by using the target version increment upgrading package. Therefore, the client can be ensured to actively pull the version increment upgrading packet under the appropriate condition, the problem of upgrading failure caused by passively receiving the upgrading packet under the condition that the client is not suitable for downloading the upgrading packet due to poor network conditions and the like is avoided, and the upgrading success rate is improved.
According to the technical scheme of the embodiment of the disclosure, the upgrading information query request which is sent by the client and contains the current version information of the object is received; determining at least one target unit upgrading packet corresponding to the object based on the current version information, the upgrading version information and the unit upgrading packet information corresponding to each unit upgrading packet; each unit upgrading package comprises a unit difference package or a unit total package which is generated by comparing each functional program unit in each stock version with the upgrading version; and generating a target version increment upgrading packet corresponding to the object by each target unit upgrading packet, and feeding back target version upgrading packet information corresponding to the target version increment upgrading packet to the client so that the client finishes upgrading the object based on the target version upgrading packet information. The method and the device realize that the unit upgrade packages are generated for all functional program units contained in each stock version (including the current version) in advance, after the current version information is obtained, the appropriate unit upgrade packages are screened from all the unit upgrade packages, and the target version increment upgrade packages adapted to the object are dynamically generated, thereby reducing the flow of comparing the content difference among different versions in real time and generating difference packages in the object upgrade process, improving the generation speed of the upgrade packages, and further improving the upgrade efficiency of the object; and the increment upgrade package replaces the full upgrade package, so that the storage cost in the upgrade process is reduced, the flow consumption in the upgrade process is saved, the download speed of the upgrade package is increased, and the object upgrade efficiency is further improved.
Fig. 2 is a flowchart of another object upgrading method provided in the embodiment of the present disclosure. The object upgrading method in fig. 2 takes the object upgrading in the vehicle as an example, and adds the related content for determining the mainstream version on the basis of the above technical solution. On the basis, the related content for generating the mainstream version increment upgrade package can be added. On the basis, whether the related content of the target version upgrading packet information exists can be further increased. In addition, related contents for upgrading push information transmission can be further added. The same or corresponding terms as those in the above embodiments are not explained in detail herein. Referring to fig. 2, the object upgrading method includes:
and S210, sending upgrading push information to the target vehicle based on the upgrading version information.
The target vehicle is a vehicle satisfying a certain preset condition, for example, the version of an object in the vehicle is lower than the upgraded version. The upgrading push information is used for triggering a client corresponding to the target vehicle to send an upgrading information query request.
After the server side determines that the upgrading version exists, upgrading push information can be generated and sent to the target vehicle so as to inform the target vehicle of starting the upgrading process of the object.
S220, receiving an upgrading information query request sent by the client, wherein the upgrading information query request comprises the current version information of the object to be upgraded.
And S230, if the current version corresponding to the current version information is lower than the set version, generating a full version upgrade package corresponding to the upgrade version information, and feeding back the version upgrade package information of the full version upgrade package as target version upgrade package information to the client.
If the current version is too old, so that the difference between the upgraded version and the current version is too large to determine a proper unit upgrade package, the object is upgraded by directly utilizing the full upgrade package of the upgraded version without executing subsequent operation, so that invalid operation is avoided, and the upgrade efficiency is further improved. In specific implementation, in order to improve the efficiency of determining the upgrade package, a limit version of an old version may be preset (i.e., a set version). If the current version is equal to or higher than the set version, the subsequent steps are executed. And if the current version is lower than the set version, the current version is considered as an old version, at the moment, all the unit upgrade packages (full packages) are utilized to generate a full upgrade package of the upgraded version, and the version upgrade package information of the full upgrade package of the version is used as target version upgrade package information and fed back to the client.
S240, counting each stock version, and determining at least one mainstream version.
The mainstream version refers to a version mainly existing in the market.
In order to further improve the object upgrading efficiency, in the embodiment of the disclosure, besides generating the unit upgrading packet of each functional program unit in each stock version in advance, the mainstream version of the object on the market is also determined in advance, and a corresponding version increment upgrading packet is generated for each mainstream version, so that the required version increment upgrading packet can be directly obtained to a great extent in the subsequent upgrading process, and the screening process and the combination process of the unit upgrading packets are further saved. Therefore, the server collects a plurality of stock version information in advance and counts the stock version information to determine at least one mainstream version.
In some embodiments, S240 comprises: counting the number of each stock version, and determining the version proportion of each stock version; and determining the stock version with the version proportion larger than or equal to the preset proportion as the mainstream version. The server side counts the quantity of each stock version collected, and calculates the proportion of each stock version in all the statistical data (namely the version proportion). Then, stock versions with version ratios exceeding a preset ratio (i.e., a preset ratio) are screened out from all stock versions as mainstream versions. As shown in fig. 3, counting the stock versions of the objects in the vehicle can obtain the following stock version-version ratio results: 1.4.18 version-92%, 1.4.12 version-5%, 1.3.11 version-2%, 1.2.7 version +1.4.13 version + … … +90.0.0 version-total 1%. Then, a preset ratio is set according to the service requirement, and the mainstream versions are determined, for example, the determined mainstream versions are 1.4.18 versions and 1.4.12 versions. This can be better compatible with most object version upgrades on the market.
And S250, determining a version increment upgrading packet corresponding to each main stream version and main stream version upgrading information corresponding to the corresponding version increment upgrading packet based on each main stream version, upgrading version information and unit upgrading packet information corresponding to each unit upgrading packet.
And aiming at each main stream version, the server compares the difference between the main stream version and the upgrade version corresponding to the upgrade version information to obtain the information of the functional program unit with the difference between the versions. Then, with the information of the functional program units with differences as query conditions, unit upgrade packages which are suitable for the mainstream version are screened from all the unit upgrade package information. And synthesizing the version increment upgrading packet corresponding to the main stream version by using the screened unit upgrading packets, and recording version upgrading information (namely main stream version upgrading information) of the version increment upgrading packet corresponding to the main stream version.
And S260, determining whether target version upgrading package information exists or not based on the current version information and the upgrading information of each mainstream version.
And the server side takes the current version information as a query condition, and queries whether the mainstream version information adaptive to the current version exists in the upgrade information of each mainstream version, namely determines whether the target version upgrade package information exists. If yes, go to S270; otherwise, S280 is executed.
And S270, feeding back the target version upgrading package information to the client so that the client can complete the upgrading of the object based on the target version upgrading package information.
And if the target version upgrading package information exists in the main stream version upgrading information, sending the target version upgrading package information to the client so that the client can pull the target version increment upgrading package according to the target version upgrading package information.
S280, determining at least one target unit upgrading packet corresponding to the object based on the current version information, the upgrading version information and the unit upgrading packet information corresponding to each unit upgrading packet.
And S290, generating a target version increment upgrading packet corresponding to the object by each target unit upgrading packet, and feeding back target version upgrading packet information corresponding to the target version increment upgrading packet to the client so that the client finishes upgrading the object based on the target version upgrading packet information.
The execution sequence of S240 to S250 is just before S260, and the sequence relationship between S210 to S230 is not limited.
According to the technical scheme of the embodiment of the disclosure, at least one mainstream version is determined by counting each stock version; determining a version increment upgrading packet corresponding to each main stream version and main stream version upgrading information corresponding to a corresponding version increment upgrading packet based on each main stream version, upgrading version information and unit upgrading packet information corresponding to each unit upgrading packet; determining whether target version upgrading package information exists or not based on the current version information and the upgrading information of each mainstream version; and if so, feeding back the target version upgrading package information to the client. The method and the device realize that the main stream version of the object on the market is further predetermined on the basis of pre-generating the unit upgrade package of each functional program unit in each stock version, and generate the corresponding version increment upgrade package for each main stream version, so that the required version increment upgrade package can be directly obtained to a great extent in the subsequent upgrade process, thereby further saving the processes of screening and combining the unit upgrade packages, and further improving the object upgrade efficiency.
