The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The upgrading method of the vehicle-mounted terminal of the unmanned automobile can be suitable for an unmanned automobile system, wherein the unmanned automobile system comprises a server and at least one unmanned automobile, the unmanned automobile is in communication connection with the server, the vehicle-mounted terminal on the unmanned automobile is provided with an application program, and the server pushes an upgrading package to the unmanned automobile so that the application program of the vehicle-mounted terminal is upgraded by installing the upgrading package on the unmanned automobile. The server may be a cloud server, such as an OTA (Over-the-Air Technology) cloud server, or may be another server, which is not described herein again. The following describes in detail the upgrading process of the vehicle-mounted terminal of the unmanned vehicle with reference to a specific embodiment.
Fig. 1 is a flowchart of an upgrading method for an unmanned vehicle terminal according to an embodiment of the present invention. The embodiment provides an upgrading method for an unmanned vehicle-mounted terminal, wherein an execution main body is a server, and the method comprises the following specific steps:
s101, the server acquires the latest version of the vehicle-mounted terminal application program.
In this embodiment, the server may first obtain which vehicle-mounted terminal applications are installed on the unmanned vehicle, obtain a current version of each application, query a production library of each vehicle-mounted terminal application whether a version is updated, and obtain a latest version of the vehicle-mounted terminal application if the version is updated.
More specifically, the obtaining, by the server, the latest version of the application program of the vehicle-mounted terminal may include:
s1011, the server searches the vehicle-mounted terminal application programs with updated versions by polling the output library of each vehicle-mounted terminal application program;
and S1012, the server acquires the corresponding latest version from the production library of the vehicle-mounted terminal application program with the updated version.
In this embodiment, the server may poll the production library of each vehicle-mounted terminal application program, sequentially determine whether each vehicle-mounted terminal application program has a version update, and if so, obtain the latest version from the production library.
S102, the server acquires the differential packet according to the latest version and a basic version pre-stored in the server.
In this embodiment, for upgrading the application program of the vehicle-mounted terminal, differential update may be adopted, that is, only the differential part is updated, so as to meet the update requirement with the minimum download amount. Existing difference updates are usually performed on the basis of the previous version, and for the test phase of the unmanned vehicle, compared with the formal operation phase, the version updates are very frequent, and may be performed many times in a day, and it is troublesome to make a difference back and forth between different versions, for example, from version 1 to version 5, a process of 1> < 2> < 3> < 4> < 5 > is required to be performed. Therefore, a base version is pre-stored locally in the unmanned vehicle, wherein the base version may be a primary version (i.e., version 1.0.0.0) of the vehicle terminal application program, and may of course be any intermediate version. And the server also stores the basic version and acquires a differential packet according to the latest version and the basic version, wherein the differential packet is a differential packet from the basic version to the latest version so that the unmanned vehicle performs differential update according to the differential packet and the basic version.
More specifically, the obtaining, by the server, the differential packet according to the latest version and a basic version pre-stored in the server may include:
s1021, the server compares the latest version with a basic version pre-stored in the server;
s1022, the server copies the newly added files, and/or deletes the deleted files, and/or performs BSDiff operation on the difference files to obtain the patch files according to the comparison result, so as to obtain the difference packet.
In this embodiment, the server obtains the difference between the latest version and the pre-stored basic version by comparing the two versions. According to the comparison result, the newly added file of the latest version which is newly added compared with the basic version can be directly copied; the files of which the latest version is deleted compared with the basic version can be directly deleted, namely, a deletion instruction is generated to identify which files need to be deleted; and for the difference file between the latest version and the basic version, namely the same file but modified, acquiring a patch (patch) file by using a BSDiff algorithm. According to the above operation, the final differential packet is obtained.
S103, the server sends the difference packet to the unmanned automobile so that the unmanned automobile can upgrade the vehicle-mounted terminal application program according to the difference packet and a locally pre-stored basic version of the unmanned automobile.
In this embodiment, after obtaining the difference packet, the server sends the difference packet to the unmanned vehicle, the unmanned vehicle performs difference update according to the difference packet and a locally pre-stored basic version of the difference packet, adds a new file to the basic version according to the difference packet, deletes the deleted file, and installs a patch on the difference file according to the patch file, so that the application program of the vehicle-mounted terminal is upgraded from the basic version to the latest version.
According to the upgrading method for the vehicle-mounted terminal of the unmanned vehicle, the latest version of the application program of the vehicle-mounted terminal is obtained through the server, and the differential packet is obtained according to the latest version and the basic version prestored in the server; and then the difference packet is sent to the unmanned automobile so that the unmanned automobile can upgrade the application program of the vehicle-mounted terminal according to the difference packet and the basic version which is pre-stored locally in the unmanned automobile. The method of the embodiment simplifies the upgrading operation of the application program of the vehicle-mounted terminal of the unmanned vehicle, improves the upgrading efficiency, facilitates version management, and simultaneously improves the safety and reliability of the upgrading process.
On the basis of the above embodiment, as shown in fig. 2, after S101 and before S102, the method may further include:
s201, the server inquires version information of a basic version which is prestored locally in the unmanned vehicle;
s202, the server acquires the basic version according to the inquired version information of the basic version.
In this embodiment, after the server acquires the latest version of the application program of the vehicle-mounted terminal and before the differential packet is acquired, the server may also query version information of a basic version pre-stored locally in the unmanned vehicle, so as to avoid that the basic version pre-stored by the server is different from the basic version pre-stored locally in the unmanned vehicle, and the differential packet is invalid. Of course, if the basic version pre-stored by the server is different from the basic version pre-stored locally by the unmanned vehicle, the server acquires the version same as the basic version pre-stored locally by the unmanned vehicle according to the version information, and then acquires the differential packet based on the newly acquired basic version.
Further, if the server does not inquire version information of a basic version pre-stored locally in the unmanned vehicle, a full package is generated according to the latest version of the vehicle-mounted terminal application program, and the full package is sent to the unmanned vehicle, so that the unmanned vehicle can upgrade the vehicle-mounted terminal application program according to the full package.
In this embodiment, if the server does not inquire the version information of the local pre-stored basic version of the unmanned vehicle when inquiring the version information of the local pre-stored basic version of the unmanned vehicle, which indicates that the local pre-stored basic version of the unmanned vehicle is lost or damaged, a full package is pushed to the unmanned vehicle, so that the unmanned vehicle upgrades the vehicle-mounted terminal application program according to the full package.
In addition, if the unmanned vehicle finds that the local un-prestored basic version of the unmanned vehicle is not available or the local prestored basic version is damaged after receiving the differential packet, a full packet request can be sent to the server, and the server feeds back the full packet according to the received full packet request.
Fig. 3 is a flowchart of an upgrading method for an unmanned vehicle onboard terminal according to an embodiment of the present invention. The embodiment provides an upgrading method for a vehicle-mounted terminal of an unmanned automobile, wherein an execution main body is the unmanned automobile, and the method comprises the following specific steps:
s301, the unmanned vehicle receives a differential packet sent by a server, wherein the differential packet is obtained by the server according to the latest version and a basic version prestored in the server after the server obtains the latest version of a vehicle-mounted terminal application program.
In this embodiment, after the server acquires the latest version of the vehicle-mounted terminal application program, the differential packet may be acquired according to the latest version and a base version pre-stored in the server, and the differential packet is a differential packet from the base version to the latest version and is sent to the unmanned vehicle.
S302, the unmanned vehicle upgrades the vehicle-mounted terminal application program according to the difference packet and a locally pre-stored basic version of the unmanned vehicle.
In this embodiment, after receiving the differential package, the unmanned vehicle performs differential update according to the differential package and a locally pre-stored basic version thereof, adds a new file in the differential package to the basic version, deletes the deleted file, and installs a patch on the differential file according to the patch file, so that the application program of the vehicle-mounted terminal is upgraded from the basic version to the latest version.
The method for upgrading the unmanned vehicle-mounted terminal provided by this embodiment corresponds to the method for upgrading the unmanned vehicle-mounted terminal on the server side, and is not described herein again.
According to the upgrading method for the vehicle-mounted terminal of the unmanned vehicle, the latest version of the application program of the vehicle-mounted terminal is obtained through the server, and the differential packet is obtained according to the latest version and the basic version prestored in the server; and then the difference packet is sent to the unmanned automobile so that the unmanned automobile can upgrade the application program of the vehicle-mounted terminal according to the difference packet and the basic version which is pre-stored locally in the unmanned automobile. The method of the embodiment simplifies the upgrading operation of the application program of the vehicle-mounted terminal of the unmanned vehicle, improves the upgrading efficiency, facilitates version management, and simultaneously improves the safety and reliability of the upgrading process.
On the basis of the above embodiment, the method may further include:
the unmanned vehicle receives an inquiry instruction of the server for the version information of the basic version locally pre-stored by the unmanned vehicle;
and the unmanned automobile feeds back the version information of the basic version to the server according to the query instruction.
In this embodiment, after the server obtains the latest version of the application program of the vehicle-mounted terminal and before the differential packet is obtained, the server may also query version information of a basic version locally pre-stored in the unmanned vehicle, that is, the server sends a query instruction of the version information of the basic version locally pre-stored in the unmanned vehicle to the unmanned vehicle, and the unmanned vehicle feeds back the version information of the basic version, so as to prevent the basic version pre-stored in the server from being different from the basic version locally pre-stored in the unmanned vehicle, and thus the differential packet is invalid. Of course, if the basic version pre-stored by the server is different from the basic version pre-stored locally by the unmanned vehicle, the server acquires the version same as the basic version pre-stored locally by the unmanned vehicle according to the version information, and then acquires the differential packet based on the newly acquired basic version.
Further, the method may further include:
if the unmanned vehicle judges that the basic version is not pre-stored locally or is damaged, sending a full package request to the server;
the unmanned automobile receives a full package fed back by the server, wherein the full package is generated by the server according to the latest version of the vehicle-mounted terminal application program;
and the unmanned vehicle upgrades the application program of the vehicle-mounted terminal according to the full volume package.
In this embodiment, if the unmanned vehicle finds that the local un-prestored basic version of the unmanned vehicle is not available or the local prestored basic version is damaged after receiving the difference packet, the difference packet cannot be updated at this time, so that the difference packet request can be sent to the server, and the server feeds back the total packet according to the received total packet request. Of course, the driverless vehicle may also request only the base version from the server, and then upgrade using the steps of S301 and S302.
