For example, version V1 of the vehicle to be upgraded, version V2 of the target vehicle, then the differential upgrade package may be denoted as V2-V1.
Step S103, when the target vehicle exists, the differential upgrade package of the current version is acquired from the target vehicle through the ad hoc network.
In the embodiment of the invention, after the vehicle to be upgraded synchronizes the version information to all surrounding vehicles in the ad hoc network, if the target vehicle with the version higher than that of the vehicle to be upgraded exists, the target vehicle can send prompt information to the vehicle to be upgraded so as to prompt the vehicle to be upgraded to need to be subjected to version upgrading. Certainly, the vehicle to be upgraded can also actively inquire the version information of surrounding vehicles, then the vehicle to be upgraded is identified and judged, and when the target vehicle is judged to exist, the neural differential upgrade package for the current version of the vehicle to be upgraded is acquired from the target vehicle through the established ad hoc network.
The differential upgrade package may be stored on the target vehicle, and the stored differential upgrade package may be an upgrade package that is not deleted locally after the target vehicle is upgraded. When the vehicle to be upgraded requests the differential upgrade package, the differential upgrade package can be directly obtained from the target vehicle. Certainly, in the embodiment of the present invention, the vehicle to be upgraded may also enable the target vehicle to download the differential upgrade package from the background server instead, that is, the target vehicle capable of being connected to the background server is used to download the differential upgrade package, and then the differential upgrade package is sent to the vehicle to be upgraded through the ad hoc network. In another alternative embodiment, the differential upgrade package may also be self-made by the target vehicle. Specifically, the current version of the vehicle to be upgraded can be sent to the target vehicle, the target vehicle performs difference between the version of the target vehicle and the version of the vehicle to be upgraded, a corresponding difference upgrade package is generated by self, and then the vehicle to be upgraded directly acquires the manufactured difference upgrade package.

Specifically, in the embodiment of the present invention, in the upgrading process, before the vehicle to be upgraded acquires the differential upgrade package, the target vehicle first sends the upgrade related information, such as information of the differential package and the whole package of MD5, length, and the like, to the vehicle to be upgraded. And then the vehicle to be upgraded sends confirmation information to the target vehicle to confirm that the upgrade is required. And after the target vehicle confirms the information, sending a differential upgrade package to the vehicle to be upgraded. And the vehicle to be upgraded verifies the obtained differential upgrade package, and after the verification is passed, the vehicle to be upgraded is subjected to package combination and upgrade to complete the update of the current version.
According to the embodiment of the invention, the vehicle to be upgraded forms an ad hoc network by networking with surrounding vehicles, and then the ad hoc network is utilized to acquire the differential upgrade package from the target vehicle with a high surrounding version for version upgrade, so that the vehicle to be upgraded can complete version upgrade without being connected to a background server through a mobile communication network such as GPRS (general packet radio service), the problem that the vehicle to be upgraded cannot be connected to the background server in the prior art so as to cause upgrading cannot be solved, and the technical effect of normally completing upgrade under the condition of poor vehicle network signals can be realized.
As an optional implementation manner, in an embodiment of the present invention, the acquiring, by the ad hoc network, the differential upgrade package of the current version to the target vehicle includes: sending an upgrade package request to the target vehicle, wherein the upgrade package request is used for requesting the target vehicle to send the differential upgrade package; and if the downloaded differential upgrade package is stored in the target vehicle, receiving the differential upgrade package downloaded by the target vehicle.
After the ad hoc network is formed, if a target vehicle with a high version exists in surrounding vehicles, the vehicle to be upgraded can send an upgrade package request to the target vehicle to request the target vehicle to send a differential upgrade package, wherein the upgrade package request can carry current version information of the vehicle to be upgraded, and is used for the target vehicle to inquire and determine the differential upgrade package. At this time, the target vehicle may query whether the differential upgrade package exists in its own storage area, where the query condition may be current version information of the vehicle to be upgraded and its own version information. When the differential upgrade package is inquired, the downloaded differential upgrade package is stored in the target vehicle, for example, the differential upgrade package is not deleted after the target vehicle is upgraded; then the differential upgrade package can be directly sent to the vehicle to be upgraded; and the vehicle to be upgraded receives the differential upgrade packet sent by the target vehicle, and then the version upgrade is carried out. For a specific upgrade process, reference may be made to the above embodiments, which are not described herein again.
According to the embodiment of the invention, whether the downloaded differential upgrade package exists or not is judged when the target vehicle is inquired, and when the differential upgrade package exists on the target vehicle, the differential upgrade package can be directly sent to the vehicle to be upgraded by using the ad hoc network for version upgrade, and the upgrade can be completed without being connected to a background server, so that the upgrade efficiency is improved.

And after the target vehicle receives the manufacturing request, analyzing to obtain a version package of the vehicle to be upgraded, namely a software package. For example, the version V1 of the vehicle to be upgraded and the version V2 of the target vehicle may be represented as V2-V1, the target vehicle may generate a V2-V1 differential upgrade package by using the software package of the version V1 and the software package of the version V2, and then transmit the differential upgrade package to the vehicle to be upgraded, and the vehicle to be upgraded performs version upgrade after receiving the differential upgrade package.
In the embodiment of the invention, the target vehicle can download the differential upgrade package to the background server instead of playing the role of a transfer station, so that the connection between the vehicle to be upgraded and the background server is indirectly realized, and the vehicle to be upgraded can acquire the latest upgrade package to upgrade the version even though the vehicle to be upgraded cannot be connected to the background server; the mode of making the differential upgrade package on the target vehicle can be without being connected to the background server, that is, if the target vehicle can not be connected to the background server temporarily, the differential upgrade package can be made through the version of the target vehicle and the version of the vehicle to be upgraded, and then the differential upgrade package is sent to the target vehicle through the ad hoc network without being connected to the background server, so that the off-line upgrade by using the ad hoc network is realized, and the load of the background server can be reduced.
An optional vehicle upgrade method according to an embodiment of the present invention is shown in fig. 2, and includes:
step S201, networking with surrounding vehicles.
Step S202, synchronizing vehicle version information in the ad hoc network.
Step S203, determining whether the target vehicle has a differential upgrade patch, if so, executing step S206, otherwise, executing step S204 or step S205. The version of the target vehicle is higher than that of the vehicle to be upgraded
And step S204, the vehicle to be upgraded sends a manufacturing request to the target vehicle, and the target vehicle locally manufactures the differential upgrade package.

Step S206, the target vehicle sends upgrading information to the vehicle to be upgraded, wherein the upgrading information comprises information such as a differential upgrading package or a whole package of MD5 and length.
And step S207, the vehicle to be upgraded sends confirmation information to the target vehicle to confirm that the upgrade can be carried out.
And step S208, after receiving the confirmation information, the target vehicle sends a differential upgrade package to the vehicle to be upgraded.
And S209, the vehicle to be upgraded checks the differential upgrade package.
And step S210, after the differential upgrade package passes verification, the vehicles to be upgraded are packaged and upgraded.
The vehicle upgrading method provided by the embodiment of the invention is also suitable for vehicles which have abnormal software APP Or System (OS) and cannot be started normally or restarted continuously. Specifically, in the embodiment of the present invention, the automatically networking with surrounding vehicles to form an ad hoc network includes: judging whether the local system of the vehicle to be upgraded is abnormal or not; when the local system of the vehicle to be upgraded is abnormal, automatically networking with surrounding vehicles to form the ad hoc network; sending current hardware information to the surrounding vehicles through the ad hoc network and requesting a complete upgrade package; and receiving the complete upgrading packet sent by the surrounding vehicles, and upgrading the vehicle to be upgraded.
Specifically, in the bootloader stage, the vehicle to be upgraded judges that the system is in an abnormal state (which can be realized by an external counter chip or a flash write flag), starts automatic networking, and sends current hardware information and a request complete software package to the external vehicle. And the surrounding vehicles receive the request data of the vehicle to be upgraded and send the complete upgrade package and the upgrade related information (the complete package MD5, length and the like) to the vehicle to be upgraded.
Optionally, in an embodiment of the present invention, the upgrading the vehicle to be upgraded includes: writing the complete upgrade package into a flash memory area corresponding to the current version; checking the complete upgrade package; and after the verification is passed, controlling the local system of the vehicle to be upgraded to restart, and finishing the upgrade.
