And establishing a differential update task with a new update package at the OTA cloud, and setting an update time limit.

Step 2: when the IGON or the engine of the vehicle to be upgraded is received, the vehicle end can be automatically connected with and communicated with the OTA cloud end after receiving the IGON signal, and the vehicle end gateway reads the current software version number of the current controller to be upgraded at the vehicle end and reports the version number to the OTA cloud end by the TBOX. And the cloud end compares the new upgrade package with the current vehicle end version upgrade package. And (4) utilizing a BSDIFF difference algorithm to make a difference packet.

And step 3: after the OTA cloud differential packet is manufactured, the vehicle cloud downloads and pushes the differential packet generated by the OTA cloud to the vehicle end by using a remote 4G downloading technology.

And 4, step 4: after the vehicle end receives the differential packet transmitted from the cloud end, the vehicle end combines the vehicle end current upgrade packet and the differential packet into a new upgrade packet by using a BSPATCH algorithm on the basis of the vehicle end current upgrade packet. The vehicle end new upgrade package is consistent with the cloud end new upgrade package. The vehicle end version upgrading package cannot disappear at the current vehicle end, and rollback upgrading of the vehicle end is supported.

And 5: and under the condition that the vehicle meets the installation condition, the vehicle end carries out full update according to the new upgrade package.

Step 2: after the vehicle to be upgraded is powered on, the TBOX (remote control module) is awakened, after certificate authentication is passed, the TBOX is communicated with the OTA cloud, and the version is reported every 5 minutes. And when the engine is not started, the OTA cloud end obtains the vehicle control unit version according to the cache. And after the engine is started, the gateway automatically collects the version of the whole vehicle and updates the cache.

And step 3: and the OTA cloud task starts to run after the vehicle end is awakened, and version comparison is carried out according to the version number reported by the vehicle end. And if the current vehicle end version is different from the software version to be upgraded, performing differential upgrading, and if the current vehicle end version is the same as the software version to be upgraded, directly displaying that the upgrading is successful.

And 4, step 4: the cloud end utilizes a difference algorithm (BSDIFF) to generate the difference packet.

And 5: and after the cloud terminal differential packet is generated, a request downloading instruction is sent to the vehicle terminal. If the vehicle end opens the automatic updating button, the vehicle end can automatically reply a download confirmation signal to the cloud end, and then the download is started immediately. If the vehicle end does not start the automatic updating, the cloud end can send a pop-up window downloading instruction to the vehicle end TBOX, the TBOX transmits the pop-up window downloading instruction to the IVI, and after the vehicle end downloads the prompt pop-up window, a user clicks to confirm downloading.

Step 6: after downloading, the vehicle end performs differential restoration (BSPATCH). Integrating the difference package downloaded from the cloud end with the upgrade package of the current version of the vehicle end, and performing overall planning on the information such as the difference, the displacement and the like to form a full package of a new version. And the new software package generated by the vehicle end is consistent with the new software package uploaded by the cloud end.

And 7: the dmclient (download manager) receives the differential restore completion signal and issues an install popup prompt.

And 8: the car end pops up the installation suggestion window, and the user can select: and 3 modes of immediate upgrading, reserved upgrading and off-vehicle upgrading are provided.

And step 9: and the vehicle end finishes updating, reports the updated vehicle end to the cloud end, and the cloud end displays the update completion.

In the embodiment of the invention, the new upgrade package is uploaded to the OTA cloud, after a new software version is available and an OTA task is established, the OTA cloud identifies the version number of the vehicle end, and a difference package of the new upgrade package and the current vehicle end upgrade package is obtained according to a BSDIFF algorithm. And downloading the differential packet from the OTA cloud end to the vehicle end by using an OTA downloading technology. And reducing the differential packet into a full packet by adopting a BSPATCH reduction algorithm, and further carrying out full upgrading on the vehicle end.
