After the vehicle-mounted terminal receives the three-level SSL verification certificate, standard one-way SSL authentication is carried out on the three-level SSL verification certificate by using the built-in CA root certificate, and after the three-level SSL verification certificate is verified to be credible, SSL encryption communication with the upgrading process server is established by the vehicle-mounted terminal.
Further, a third embodiment of the vehicle-mounted system upgrade method is provided based on the first embodiment of the vehicle-mounted system upgrade method, and in this embodiment, the upgrade package includes at least one module upgrade package corresponding to an electronic control unit of a vehicle; step S50 includes:
step a, controlling the vehicle-mounted terminal to send each module upgrading packet to the corresponding electronic control unit according to the downloaded upgrading packet;
the module upgrading packages in the upgrading packages can have respective names or numbers, after the upgrading packages are downloaded, the vehicle-mounted terminal can identify the electronic control units corresponding to the module upgrading packages through the names or numbers of the module upgrading packages in the upgrading packages, and then sends the module upgrading packages to the corresponding electronic control units. For example: the name of a module upgrading package is 'engine management system upgrading package' or 'EMS Update', and the vehicle-mounted terminal identifies that the module upgrading package belongs to the engine management system and sends the module upgrading package to the electronic control unit of the engine management system. For another example, each electronic control unit of the vehicle has a respective number, and the respective number information is preset in the vehicle-mounted terminal, and if the number of a module upgrade package is 2, and the number 2 preset in the vehicle-mounted terminal corresponds to a Transmission Control Unit (TCU), the vehicle-mounted terminal can identify that the module upgrade package belongs to the transmission control unit, and then send the module upgrade package to the transmission control unit.
And b, controlling each electronic control unit to carry out firmware upgrading according to the received module upgrading package.
After each electronic control unit receives the corresponding module upgrading packet sent by the vehicle-mounted terminal, each electronic control unit is installed according to the corresponding module upgrading packet to realize upgrading, and the electronic control units needing upgrading respectively execute installation of the corresponding module upgrading packets, so that the time of the whole installation and upgrading process is saved.
Further, a fourth embodiment of the vehicle-mounted system upgrading method according to the present invention is provided based on the foregoing embodiment of the vehicle-mounted system upgrading method according to the present invention, and in this embodiment, the step of controlling the vehicle-mounted terminal to send each of the module upgrading packages to the corresponding electronic control units according to the downloaded upgrading package includes:

And d, controlling the vehicle-mounted terminal to send the module upgrading packets to the corresponding electronic control units through an Ethernet interface according to a preset protocol under the condition that the whole vehicle is awakened.
In this embodiment, for example: after the whole vehicle-mounted system is awakened, the vehicle-mounted terminal performs DOIP protocol command interaction with each electronic control unit through the 100M Ethernet interface, and the command can be in a preset request code form. The vehicle-mounted terminal sequentially transmits request codes SID of 0x10 and 0x03 to each electronic control unit to enter an expansion mode according to the name or the serial number of the module upgrading packet, SID is a service identifier, the following codes represent service types, the vehicle-mounted terminal transmits the request codes SID of 0x85 to each electronic control unit to close a fault code module of each electronic control unit, the vehicle-mounted terminal transmits the request codes SID of 0x28 to each electronic control unit to close a communication module of each electronic control unit, the vehicle-mounted terminal transmits the request codes SID of 0x10 and 0x02 to each electronic control unit to request each electronic control unit to enter a programming mode, the vehicle-mounted terminal transmits the request codes SID of 0x27 to each electronic control unit to request each electronic control unit to perform safe access, and the vehicle-mounted terminal sequentially transmits the module upgrading packet to each electronic control unit according to the offset. In the process of the transmission module upgrading packet, the Ethernet interface is used for replacing a traditional 0.5M CAN bus, so that the problems that the transmission time in a vehicle is long and the vehicle feeding is easily caused due to the fact that the transmission speed cannot meet the transmission requirement of the upgrading packet with large capacity due to the limitation of distance CAN be avoided. The vehicle-mounted terminal and each electronic control unit directly transmit the upgrade package through a 100M Ethernet interface, the transmission rate is improved by at least 200 times, and the time required by upgrade is greatly shortened.
As shown in fig. 4, a fifth embodiment of the vehicle-mounted system upgrading method according to the present invention is further proposed based on the first embodiment of the vehicle-mounted system upgrading method according to the present invention, and in this embodiment, the step of controlling each electronic control unit to perform firmware upgrading according to the received module upgrading package includes:

if each electronic control unit is consistent with the corresponding module upgrade package, executing step S500: and controlling each electronic control unit to carry out firmware upgrading according to the received module upgrading packet.
In this embodiment, for example: when the transmission of the module upgrading packet is judged to be finished, the vehicle-mounted terminal sends a request code SID of 0x31 and 0xFF01 to each electronic control unit to request each electronic control unit to carry out consistency check, the command is an asynchronous command, each electronic control unit can immediately carry out consistency check on the received module upgrading packet after receiving the command and generate a consistency result record, and the consistency result record is fed back to the vehicle-mounted terminal. And under the condition that the vehicle-mounted terminal judges that each electronic control unit is consistent with the corresponding module upgrading package according to the consistency result, each electronic control unit starts to install the received module upgrading package, and the vehicle-mounted terminal can continuously inquire the installation progress result of each electronic control unit through inquiring an upgrading result request code SID (0 x 31) and 0xFF02 in the whole installation upgrading process. And after the installation and the upgrade are finished, the vehicle-mounted terminal reports the upgrade result of the vehicle-mounted system to the upgrade process server.

if yes, go to step 50.
In this embodiment, the preset period may be 10S, 30S, or 60S, and may be set according to actual needs, which is not limited herein. For example: the vehicle-mounted terminal downloads the upgrade package from the content distribution server and simultaneously monitors the download rate in real time according to the link of the upgrade package, calculates and acquires the download average transmission rate in a 30S period every 30S period, judges whether the average transmission rate is 0, if 0, the average transmission rate is possibly caused by network faults, vehicle faults or other reasons, and possibly the upgrade package is downloaded completely, then judges whether the upgrade package is complete by the vehicle-mounted terminal, and carries out firmware upgrade according to the downloaded upgrade package under the complete condition.
In another embodiment, after the step of determining whether the upgrade package is complete if the average transmission rate is 0, the method further includes:
if not, go to step S60: generating a log of download failure and entering a sleep mode;
