Technical Field

The present application relates to the field of new energy automobiles, and in particular, to an OTA upgrading method, an OTA upgrading device, an electronic device, and a storage medium.

Background

OTA (Over the Air Technology), i.e., space download technology, an automobile OTA upgrade refers to a firmware upgrade and/or software upgrade to an automobile using over-the-air technology.

The current OTA upgrades basically perform upgrade brushing on the upgraded components (such as ECU) by the OTA master control, and each upgraded component receives the upgrade brushing "passively". Because the 'passive' upgrading and writing mode can upgrade and write the upgraded parts no matter whether the upgraded parts have upgrading and writing requirements, the OTA master control can upgrade and write the upgraded parts, so that a large amount of network bandwidth is required to be consumed, the potential of OTA upgrading is difficult to fully develop, and the upgrading efficiency is low.

Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

An OTA upgrading method and device according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic view of an application scenario according to an embodiment of the present application. The application scenario may include an OTA upgrade master 101, an upgrade requester 102, other upgrade requesters 103, a server 104.

The OTA upgrade master 101 may be an OTA upgrade master (abbreviated as "UMC") carried in VBOX (Vehicle BOX).

The upgrade requesting party 102 and the other upgrade requesting party 103 may be a whole Vehicle Gateway (VGW), or may be an ECU (Electronic Control Unit ) unit suspended under the whole vehicle gateway, or may be IVI (In-vehicle info ainment, in-vehicle infotainment system) or the like. The upgrade demanded party 102 and the other upgrade demanded party 103 are different upgrade demanded parties, for example, when the upgrade demanded party 102 is the ECU1 hung under the whole vehicle gateway 1, the other upgrade demanded party 103 may be other ECU components or whole vehicle gateways (such as VGW2, VGW3 … …), IVI, and the like besides the ECU 1.

The whole vehicle gateway carries an OTA upgrade agent (UA for short); each ECU carries an OTA upgrade slave (abbreviated as "US").

The OTA upgrade master control 101, the upgrade requiring party 102 and the server 104 can be respectively connected through 100M/1000M Ethernet (EHT); the upgrade required party 102 and the other upgrade required parties 103 may be connected via 100M/1000M ethernet.

The server 104 may be a server, a server cluster formed by a plurality of servers, or a cloud computing service center, which is not limited in this embodiment of the present application.

Fig. 2 is a schematic diagram of a system architecture of an OTA upgrade system according to an embodiment of the present application. For convenience of description, only parts related to the embodiments of the present application are shown in the drawings.

As shown in fig. 2, the OTA upgrade system includes an OTA upgrade master 101, an upgrade requester 102, other upgrade requesters 103, and a server 104.

The OTA upgrade master 101 includes a remote control/V2X (vehicle to vehicle)/OTA master service layer, an atomic service layer, a device abstraction layer, middleware, an operating system, and a hardware layer. The atomic service layer comprises a plurality of atomic services, such as request downloading, version pushing, version detecting, request upgrading, file signature checking, communication algorithm, release upgrading, file (self) upgrading, encryption and decryption and the like. The middleware comprises SOMEIP/MQTT/DOIP/UDS protocol stack. Each atomic service corresponds to a single function interface.

As an example, the upgrade requester 102 is the ECU1-1 hooked under the whole vehicle gateway 1 (VGW 1), and the other upgrade requesters 103 are IVIs connected with the whole vehicle gateway 1 (VGW 1). The upgrade required party 102 includes a composite service layer (implementing the composite functionality of multiple atomic services), an atomic service layer, a device abstraction layer, middleware (including SOMEIP/MQTT/DOIP/UDS protocol stacks), an operating system, and a hardware layer. Other upgrade requesters 103 include an audio-visual entertainment/OTA service layer, an atomic service layer (including multiple atomic services such as human-machine interaction, music playing, file downloading, file (self) upgrade, request download, subscription upgrade, etc.), a device abstraction layer, middleware (including a SOMEIP/MQTT/DOIP/UDS protocol stack), an operating system, and a hardware layer.

The OTA upgrade master 101, the upgrade requesters 102, the other upgrade requesters 103, and the server 104 may implement "subscription-publish" communication through a SOME/IP (Scalable service-Oriented Middle ware over IP) protocol. SOME/IP is one of the protocols implementing SOA (Service-oriented architecture). The in-vehicle ethernet includes an application layer, a transport layer, a network layer, a data link layer, and a physical layer. The SOME/IP is based on the UDP/TCP protocol of the transmission layer, has a specific service interaction mechanism, broadcasts and informs other nodes in the domain after the service is on line, and requests or subscribes to related service interfaces after the other nodes receive the service broadcast, which is different from the communication mode of the traditional vehicle-mounted network, when the request is sent, the SOME/IP only sends data, otherwise, the SOME/IP does not send the data, so that unnecessary data is not needed on the bus, and the system load is reduced. With the continuous development of an automobile communication bus and an entire automobile electronic and electric architecture, a signal-oriented communication mode based on a CAN bus cannot meet the development requirement of an intelligent automobile SOA architecture, and an SOME/IP protocol is one of the communication protocols for realizing the SOA architecture at present.

The SOME/IP protocol manages data information in units of service elements, which can be classified into Event, method, field three types. Event is a unidirectional data transmission mode, and Server publishes service Event to subscriber; method is a communication mode of remote function call; fields, like a combination of Event and Method, allow clients to obtain/set/subscribe to state information for Server-side events. The transmission and sharing of the data information is realized through Service Interface.

It should be noted that, the specific types, numbers, combinations, and the like of the OTA upgrade master control 101, the upgrade requester 102, the other upgrade requesters 103, and the server 104 may be adjusted according to the actual requirements of the application scenario, and the present application is not limited in this disclosure.

Fig. 3 is a flow chart of an OTA upgrading method according to an embodiment of the present application. The OTA upgrade method of fig. 3 may be performed by the upgrade requester 102 of fig. 1. As shown in fig. 3, the OTA upgrading method includes:

step S301 submits a first upgrade service application to an OTA upgrade master control, where the first upgrade service application includes first identification information and a first subscription event group corresponding to the first identification information, and the first subscription event group includes at least one first subscription content.

The first identification information refers to identification information of the upgrade requiring party 102, and may be, for example, an ID, a digital code, or the like.

The first subscription content generally refers to content such as an upgrade software name and an upgrade version number that the upgrade requester 102 wants to subscribe to according to actual requirements.

The first subscription event group, which is a collection that includes respective first subscription content, is used to characterize all upgrade services that the upgrade requester 102 wants to subscribe to.

For example, if the upgrade requester 102 wants to subscribe to the latest upgrade versions of the four types of software, "QQ", "WeChat", "headline" and "firmware upgrade update", the first subscription event group includes [ (a, up-to-date), (B, up-to-date), (C, up-to-date), (D, up-to-date) ], for a total of four first subscription contents. Wherein (A, up-to-date) is a first subscription content, A represents "QQ", up-to-date represents the latest version; (B, up-to-date) is a first subscription content, B represents "WeChat", up-to-date represents the latest version; (C, up-to-date) is a first subscription content, C represents a 'header', and up-to-date represents the latest version; (D, up-to-date) is a first subscription content, D represents "firmware upgrade update", and up-to-date represents the latest version.

In step S302, when receiving the first upgrade file corresponding to each first subscription content transmitted by the OTA upgrade master control, the upgrade and refresh are performed using the first upgrade file, and a broadcast message is issued, where the broadcast message at least includes the first version information of the first upgrade file.

To facilitate understanding, continuing with the above example, the first upgrade file corresponding to the first subscription content (a, up-to-date) is the latest upgrade version file of "QQ"; the first upgrade file corresponding to the first subscription content (B, up-to-date) is the latest upgrade version file of WeChat; the first upgrade file corresponding to the first subscription content (C, up-to-date) is the latest upgrade version file of the 'headline'; the first upgrade file corresponding to the first subscription content (D, up-to-date) is the latest upgrade version file of "firmware upgrade update".

In an embodiment, after the upgrade demander 102 obtains the first upgrade files of the four first subscription contents, the first upgrade files may be temporarily stored in a preset storage space, and then, according to practical situations (such as network bandwidth, user request, etc.), the four software applications including "QQ", "WeChat", "header" and "firmware upgrade update" may be optionally upgraded by using the four first upgrade files at the same time, or one or two or three of the first upgrade files may be used to upgrade the corresponding software applications in batches at different time periods, so as to implement that one upgrade demander upgrades a plurality of different software applications at the same time.

In another embodiment, after receiving the first subscription event group of the upgrade requester 102, if the server 104 is confirmed to have the first upgrade file corresponding to the first subscription content in the first subscription event group, the OTA upgrade master control 101 may directly upgrade and write the corresponding software of the upgrade requester 102, without transmitting the first upgrade file to the upgrade requester 102, and then the upgrade requester 102 performs upgrade and write by itself, thereby simplifying the intermediate transmission flow of the first upgrade file and improving the upgrade efficiency.

Step S303, receiving a second upgrade service application sent by the other upgrade requiring party, where the second upgrade service application includes second identification information and a second subscription event group corresponding to the second identification information, and the second subscription event group includes at least one second subscription content.

The second identification information refers to identification information of other upgrade required parties 103, and may be, for example, an ID, a digital code, etc.

The second subscription content generally refers to the content such as the name of the upgrade software and the upgrade version number that the other upgrade requester 103 wants to subscribe to according to its actual requirement.

The second subscription event group, which is a collection including respective second subscription contents, is used to characterize all upgrade services that other upgrade requesters 103 want to subscribe to.

For example, if the other upgrade requester 103 wants to subscribe to the latest upgrade versions of both "QQ" and "WeChat" software applications, the second subscription event group includes [ (A, up-to-date), (B, up-to-date) ], for a total of two second subscriptions. Wherein (A, up-to-date) is a second subscription content, A represents "QQ", up-to-date represents the latest version; (B, up-to-date) is a second subscription content, B represents "WeChat", and up-to-date represents the latest version.

Step S304, determining the first upgrade file corresponding to the second subscription content as a target upgrade file, and sending the target upgrade file to other upgrade requesters so that the other upgrade requesters use the target upgrade file to update and write.

As an example, assuming that the upgrade requester 102 receives the second subscription event group of the other upgrade requester 103 as [ (a, up-to-date) ], the upgrade requester 102 may first search whether the "QQ" latest version file corresponding to the second subscription content (a, up-to-date) and the "WeChat" latest version file corresponding to the second subscription content (B, up-to-date) are stored in its storage space. If so, the "QQ" latest version file and the "WeChat" latest version file acquired from the OTA upgrade master 101 are determined as target upgrade files, and these target upgrade files are sent to other upgrade requesters 103.

If the upgrade requester 102 searches to find that there is no "QQ" latest version file corresponding to the second subscription content (a, up-to-date) in its storage space, a message of unsuccessful subscription may be returned to the other upgrade requester 103. Thereafter, the other upgrade requester 103 may itself issue a third upgrade service application to the OTA upgrade master 101, where the third upgrade service application includes a second subscription content (a, up-to-date) to obtain a corresponding "QQ" latest version file.

According to the technical scheme provided by the embodiment of the application, the upgrading requirement party can be used as an upgrading service requirement party and also can be used as an upgrading service provider. When the upgrade demand party is used as an upgrade service demand party, the upgrade demand party can actively apply for the first upgrade file required by the upgrade demand party to the OTA upgrade master control when the upgrade demand is met, the traditional mode of 'passive' receiving upgrade refreshing is broken, the 'active' upgrade refreshing is realized, and the 'subscription-release' communication mode is beneficial to saving a large amount of network bandwidth. When the upgrade requiring party is used as an upgrade service provider, upgrade services (including upgrade file downloading and other services) can be provided for other upgrade requiring parties, so that the mode of OTA upgrade is more flexible and diversified, and the potential of OTA upgrade is fully exerted. By the method, one upgrade requiring party can upgrade a plurality of different applications at the same time, and the same application can be upgraded at the same time by the plurality of different upgrade requiring parties, so that the upgrade efficiency is effectively improved.

In some embodiments, in the step S301, submitting the first advanced service application to the OTA upgrade master, including:

acquiring an upgrade service message, upgrade index information and first identification information issued by an OTA upgrade master control, wherein the upgrade service message comprises at least one upgrade event, and each upgrade event comprises upgrade identification information and upgrade file version information corresponding to the upgrade identification information;

Determining at least one first subscription content according to the upgrade index information, the upgrade identification information and the upgrade file version information;

and submitting a first advanced service application to the OTA upgrade master control based on the first subscription content and the first identification information.

The upgrade Service message generally refers to an office Service message that is actively issued by an upgrade Service provider (such as an OTA upgrade master control) after the upgrade Service provider is ready for the upgrade Service and the upgrade Service meets the issue condition. The office Service message at least comprises upgrade identification information (such as a software name, a software ID, etc.), and upgrade file version information (such as a software version number, etc.) corresponding to the upgrade identification information.

The upgrade index information mainly refers to firmware or software which the upgrade requester wants to upgrade and software version information thereof. For example, the upgrade requiring party (e.g. IVI) wants to upgrade the two types of software of "QQ" and "WeChat" to the current latest version, and the upgrade index information includes at least the software names of "QQ" and "WeChat" and their current latest version numbers.

As an example, the OTA upgrade master 101 may actively issue an Offer Service message (i.e., an upgrade Service message) to inform other nodes in the multicast that the Service has been started after the upgrade Service is ready and the Service meets the issue condition, and may create a Service connection. The upgrade requester 102 may submit a first upgrade Service application to the OTA upgrade master 101 when it receives an Offer Service message for the relevant Service in the network and wants to access the upgrade Service.

If the upgrade requiring party 102 does not receive or temporarily does not receive the upgrade Service message issued by the OTA upgrade master control 101 in the network, the Find Service message may be sent to actively search for the Service, and if the OTA upgrade master control 101 is ready for the upgrade Service, the Offer Service message may be replied.

When the OTA upgrade master control 101 finds that the upgrade service is not available and does not meet the service release condition, it actively sends Stop Offer Service message to inform other nodes in the multicast that the upgrade service is not available, and stops service support.

As an example, assume that the upgrade requester 102 wants to subscribe to the latest upgrade versions of the four types of software, "QQ", "WeChat", "headline", and "firmware upgrade update", i.e., upgrade index information includes the software names and latest version numbers of "QQ", "WeChat", "headline", and "firmware upgrade update"; if the upgrade service message received by the upgrade requester 102 includes the software names and the latest version numbers of the four types of software, four first subscription contents (A, up-to-date), (B, up-to-date), (C, up-to-date), (D, up-to-date) may be determined. Afterwards, the upgrade requester 102 may assemble the four first subscription contents and the identity information (i.e. the first identity information) thereof into a subscription message (i.e. a subscription message), where the subscription message includes the first subscription event group [ (a, up-to-date), (B, up-to-date), (C, up-to-date), (D, up-to-date) ], and propose the first upgrade service application to the OTA upgrade master 101.

After receiving the subscription message of the upgrade requiring party 102, the OTA upgrade master control 101 needs to first determine whether the upgrade requiring party 102 meets subscription conditions (for example, determine whether the upgrade requiring party is a member user, whether the upgrade requiring party has permission to Subscribe to the service, etc.), if yes, determine that the upgrade requiring party 102 meets the event group subscription conditions, send a subscore ACK (subscription acknowledgement character), and inform the upgrade requiring party 102 that subscription is successful. After the events within the first event group are ready (i.e., the first upgrade file corresponding to the first subscription content is ready), the OTA upgrade master 101 sends the relevant events in a contracted form to the upgrade requester 102 who successfully subscribes. If the upgrade requester 102 does not meet the event group subscription condition, the OTA upgrade master 101 directly replies to the subscription ack (negative acknowledgement character) informing that the subscription was unsuccessful.

After the upgrade requester 102 subscribes to a certain event group, it finds that the following event group is not data that needs the event group, and may send a Stop Subscribe message to the OTA upgrade master 101 to unsubscribe from the corresponding event.

In some embodiments, in the step S304, the determining the first upgrade file corresponding to the second subscription content as the target upgrade file, and sending the target upgrade file to other upgrade requesters specifically includes:

If the first upgrading file corresponding to the second subscription content does not exist, forwarding the second upgrading service application to an OTA upgrading master control;

and receiving a second upgrade file corresponding to the second subscription content and issued by the OTA upgrade master control, and forwarding the second upgrade file to other upgrade requesters.

As an example, assuming that the upgrade requester 102 receives the second subscription event group of the other upgrade requester 103 as [ (a, up-to-date), (B, up-to-date) ], if the upgrade requester 102 searches to find that there is no "QQ" latest version file corresponding to the second subscription content (a, up-to-date) in its storage space, only there is a "WeChat" latest version file corresponding to the second subscription content (B, up-to-date), the "WeChat" latest version file may be determined as the target upgrade file and sent to the other upgrade requester 103. At the same time, the upgrade requester 102 may submit a fourth upgrade service application to the OTA upgrade master 101, the fourth upgrade service application including the second subscription content (a, up-to-date). After acquiring the "QQ" latest version file corresponding to the second subscription content (a, up-to-date) transmitted by the OTA upgrade master control 101, the upgrade requester 102 determines the "WeChat" latest version file as a target upgrade file and sends the target upgrade file to other upgrade requesters 103.

If neither the OTA upgrade master 101 nor the server 104 has a "QQ" latest version file corresponding to the second subscription content (a, up-to-date), then a message of unsuccessful subscription may be returned by the OTA upgrade master 101 to the other upgrade required party 103. The OTA upgrade master 101 may issue the "QQ" latest version file corresponding to the second subscription content (a, up-to-date) to the other upgrade requiring party 103 after the "QQ" latest version file corresponding to the second subscription content (a, up-to-date) exists according to the conventions of the other upgrade requiring party 103.

In some embodiments, in the step S304, the sending the target upgrade file to other upgrade requesters includes:

applying for obtaining intra-group member information from an intra-group network;

judging whether other upgrading demand parties are in-group upgrading demand parties according to in-group member information;

and if the other upgrading requirement party is the in-group upgrading requirement party, sending the target upgrading file to the other upgrading requirement party.

Referring to fig. 4, as an example, assuming that the upgrade requiring party 102 is the ECU1-1 hooked under the entire vehicle gateway VGW1, and the other upgrade requiring party 103 is the ECU1-n hooked under the entire vehicle gateway VGW1, the ECU1-1 may first send an acquisition request of the intra-group member information to the intra-group gateway (i.e., VGW 1); after receiving the intra-group member information (including identification information of the intra-group members, etc.) returned by VGW1, the ECU1-1 judges whether the identification information of the ECU1-n exists in the intra-group member information; if the identification information of the ECU1-n exists, it may be determined that the ECU1-n is a member of the VGW1 group, that is, is an in-group upgrade requiring party, and then the ECU1-1 may directly send the target upgrade file to the ECU1-n.

In other embodiments, if the other upgrading demand party is an off-group upgrading demand party, acquiring information of an off-group gateway and membership members thereof, and determining the off-group gateway to which the other upgrading demand party belongs according to the information of the off-group gateway and membership members thereof;

if the gateway outside the group and the gateway inside the group are the same-vehicle gateway group, the target upgrade file is sent to the gateway inside the group, so that the gateway inside the group sends the target upgrade file to the gateway outside the group, and the target upgrade file is sent to other upgrade demanding parties through the gateway outside the group.

Referring to fig. 4, as an example, assume that the upgrade requiring party 102 is an ECU1-1 hooked under the whole vehicle gateway VGW1, and the other upgrade requiring party 103 is an ECU2-1 hooked under the whole vehicle gateway VGW2, and the ECU1-1 finds out the intra-group member information provided by the whole vehicle gateway VGW1, where the intra-group member information does not include the identification information of the ECU2-1, so that it can be determined that the ECU2-1 and the ECU2-1 belong to different whole vehicle gateways respectively, and it can be determined that the ECU2-1 is an out-of-group upgrade requiring party. At this time, the ECU1-1 may acquire information of the outside gateway and its membership members via the whole vehicle gateway VGW1, and determine to which outside gateway the ECU2-1 belongs by searching for the information of the outside gateway and its membership members.

Assuming that the ECU2-1 is found to be the ECU member affiliated to the entire vehicle gateway VGW2, it is further confirmed whether the entire vehicle gateway VGW2 and the entire vehicle gateway VGW1 are the same vehicle gateway group (i.e., the gateways belonging to the same vehicle). If VGW2 and VGW1 are the same gateway group, the target upgrade file can be sent to VGW1, then the target upgrade file is forwarded to VGW2 through VGW1, and finally the target upgrade file is forwarded to the hooked ECU2-1 through VGW 2.

In some embodiments, if the out-of-group gateway and the in-group gateway are different vehicle gateway groups, detecting a network connection state of a network channel between the out-of-group gateway and the in-group gateway;

if the network connection state is normal, the target upgrade file is sent to the gateway in the group, so that the gateway in the group sends the target upgrade file to the gateway outside the group, and the target upgrade file is sent to other upgrade requesters through the gateway outside the group.

As an example, assume that the upgrade requiring party 102 is the ECU1-1 hooked under the whole gateway VGW1 of the first vehicle, the other upgrade requiring party 103 is the ECU3' -1 hooked under the whole gateway VGW3' of the second vehicle, and the whole gateway VGW1 and the whole gateway VGW3' are different vehicle gateway groups (i.e. gateways respectively belonging to different vehicles). Then, the ECU1-1 may detect the network connection state of the network channel between the whole vehicle gateway VGW1 and the whole vehicle gateway VGW3', for example, may determine whether the network connection state of the network channel between the whole vehicle gateway VGW1 and the whole vehicle gateway VGW3' is normal by acquiring the network card state value of the network card interface externally connected to the whole vehicle gateway VGW3' on the whole vehicle gateway VGW 1. Generally, when the network card status value is linkup, the network connection status is normal, and when the network card status value is linkdown, the network connection status is abnormal. If the network connection state is normal, the target upgrade file is sent to the whole gateway VGW1, the target upgrade file is forwarded to the whole gateway VGW3' of the second vehicle through the whole gateway VGW1, and then the target upgrade file is forwarded to the ECU3' -1 through the whole gateway VGW3 '.

Through the method, the subscription-release service communication interaction between the upgrading demand side and other upgrading demand sides of the gateways in the group, the upgrading demand side and other upgrading demand sides of the same car gateway group and the upgrading demand side and other upgrading demand sides of the different car gateway group can be realized, so that the OTA upgrading mode is more flexible and diversified, and the OTA upgrading potential is fully exerted. In addition, the upgrade service communication between the gateway in the group and the gateway in the same vehicle CAN be realized by using Ethernet or CAN bus, which CAN save a great deal of network bandwidth.

When the gateway affiliated to the upgrading demand side and other upgrading demand sides is a different vehicle gateway group, whether the distance difference value of the vehicles affiliated to the upgrading demand side and other upgrading demand sides meets the preset distance range can be further judged, if the distance difference value meets the preset distance range, the transmission of the upgrading file is realized by means of near field communication interaction, bluetooth communication interaction and the like, so that the traffic required by transmission can be saved, and the OTA upgrading cost can be reduced.

For example, assume that the upgrade requiring party 102 is an ECU1-1 hooked under the whole gateway VGW1 of the first vehicle, the other upgrade requiring party 103 is an ECU3' -1 hooked under the whole gateway VGW3' of the second vehicle, and the whole gateway VGW1 and the whole gateway VGW3' are different gateway groups. The ECU1-1 may further acquire first position information of the own vehicle (i.e., the first vehicle) and second position information of the second vehicle, and then confirm a distance difference between the two vehicles according to the first position information and the second position information; if the distance difference value meets a preset distance range (for example, less than or equal to 5 meters), the communication interaction between the whole gateway VGW1 and the whole gateway VGW3 'CAN be switched to a near field communication mode or a Bluetooth communication mode, and based on the near field communication interaction or the Bluetooth communication interaction, the whole gateway VGW1 transmits the target upgrade file to the whole gateway VGW3', and then the target upgrade file is forwarded to the ECU3'-1 through the whole gateway VGW3' through an Ethernet/CAN bus.

In some embodiments, the above OTA, the method for upgrading may further include the following steps:

after the broadcast message is issued, when the accumulated time reaches the preset duration and a second upgrade service application sent by other upgrade requiring parties is not received yet, judging whether the upgrade refreshing flow using the first upgrade file to carry out upgrade refreshing is finished completely;

and if the updating and refreshing process of the updating and refreshing by using the first updating file is completely finished, all the first updating files are emptied.

The preset duration can be flexibly set according to practical situations, for example, can be set to 24 hours, 48 hours and the like.

As an example, assuming that the preset duration is 24 hours, the upgrade requiring party 102 starts to count after issuing the broadcast message, and when the accumulated time reaches 24 hours and the second upgrade service application sent by other upgrade requiring parties is not yet received, it is firstly determined whether the brushing flow of brushing by using the first upgrade file is completely finished; if it has been completely finished, all the first upgrade files in its storage space are emptied to release the occupied content.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein.

Fig. 5 is a flowchart of another OTA upgrading method according to an embodiment of the present application.

Taking an upgrade service demand side as an ECU, an upgrade service provider as a UMC as an example, the OTA upgrade process on the ECU side is approximately as follows: firstly, an ECU subscribes the upgrade service of the ECU to UMC by calling a SOME/IP service interface; then, judging whether the subscription is successful or not according to the response ACK returned by the UMC; if the subscription is successful, judging whether an upgrade version pushed by the UMC exists or not; if the updated version pushed by the UMC exists, further confirming whether the new version is updated or not; if the updated version is confirmed, calling a request file downloading service in an atomic service layer to download a corresponding ECU file (namely an updated version file pushed by the UMC) from the UMC; then, judging whether an ECU file downloading completion notification sent by the UMC is received or not; if the ECU file downloading completion notification sent by the UMC is received, calling a file updating and refreshing service in an atomic service layer to update the file; then, inquiring whether the ECU file installation is completed or not; if the installation is completed, the method exits.

The TSP (server) serves as an OTA service provider and mainly provides an upgrade version and a file of the ECU, manages upgrade files of each ECU, and can acquire related upgrade files from the server via VBOX when each ECU needs to be upgraded.

For UMC/UA/US they both act as service providers as well as service requesters. Between UMC and TSP, UMC is service demander, and version information and file upgrade package of ECU to be upgraded are needed to be obtained from TSP.

UMC, UA, US, UMC/UA/US can be used as both a service provider and a service requester to upgrade and refresh the files of OTA according to the upgrade service of OTA provided by the own system.

The SOA SOMEIP OTA upgrade service content includes, but is not limited to, "remind the user of new version update, ask the user to confirm", "download instruction to control the download", "upgrade instruction to control the upgrade", "request the download", etc.

In one embodiment, assuming that the upgrade requestor 102 is IVI, VI subscribes to the OTA upgrade master 101 for the upgrade event group (i.e., subscribes to these upgrades) requirements of "QQ, weChat, headline" and "firmware upgrade update" at the same time, the OTA upgrade master 101 synchronizes these subscription requirements to the TSP. If the TSP has these services, the upgrade files will be downloaded to the IVI (or VBOX temporary) part via the OTA upgrade master 101 channel for upgrade swiping, so that different applications can be upgraded simultaneously at one upgrade requester 102. If not, the subscription message is saved, and if the new version and file exist, the subscription component is notified with the notification published message.

In another embodiment, assume that the upgrade required party 102 is the entire gateway VGW1, VGW2, VGW3, and VGW4, which subscribe to the OTA upgrade master 101 for the upgrade event group (i.e. subscribe to the upgrade) requirements of "TCP/IP END" and the like, at the same time, the OTA upgrade master 101 synchronizes these subscription requirements to the TSP. If the TSP has these services, the OTA upgrade master control 101 downloads these upgrade files to VGW1, VGW2, VGW3 and VGW4 for upgrade and writing, so that the same upgrade file data packet can be upgraded on multiple upgrade requiring sides. If not, the subscription message is saved, and if the new version and file exist, the subscription component is notified with the notification published message.

Through the mode, each upgrade requiring party can realize that one upgrade requiring party upgrades a plurality of different application programs simultaneously by publishing or subscribing the same or different OTA upgrade services, and can also realize that a plurality of upgrade requiring parties upgrade the same application program in parallel, so that the 'thousands of people and thousands of sides' OTA customized upgrade service can be realized.
