Figure, as shown in Figure 1, comprising the following steps:
Whether step 101, detection vehicle meet default promotion condition.
It should be noted that the triggering whether the detection vehicle meets default promotion condition can be, there are many situations.
For example, in oneainstance, can be in the case where vehicle receives software upgrade instruction, for example, can be vehicle with cloud
In the case that end server establishes connection, such as cloud server sends software upgrade instruction to vehicle, and then vehicle is receiving
It to after the software upgrade instruction, can be whether vehicle detection itself meets default promotion condition, or be also possible to cloud clothes
Device be engaged in detect whether vehicle meets default promotion condition；It can certainly be that mobile terminal refers to vehicle transmission software upgrading
It enables, or can also be other exterior terminals, as host computer sends software upgrade instruction to vehicle.
Alternatively, in another scenario, can be when detecting that vehicle enters specific software upgrade procedure, then detect
Whether the vehicle meets default promotion condition.
In the embodiment of the present invention, the default promotion condition includes: that power supply is in close pattern, closing of the door and central controlled lock

The upgrade file passes through integrity verification.
Specifically, after vehicle obtains the upgrade file, vehicle be can be through " checking a programming integrality " example
Process control activates ECU integrity verification, and when ECU receives this service request, Bootloader will calculate upgrade file
First validation value of data byte, and compare the first default validation value phase whether first validation value sends with exterior terminal
Matching, if matching, determines that the integrity verification of the upgrade file passes through.
Optionally, vehicle can be through CRC32 algorithm verify the upgrade file all data bytes whether by
Correct transmission and write-in, that is to say, that Bootloader will calculate the CRC32 value of the data byte of upgrade file, and will calculate
The request message that is sent with host computer of the CRC32 value in default CRC32 value be compared, if the CRC32 calculated
Value is consistent with the default CRC32 value that host computer is sent, then determines that the integrity verification of the upgrade file passes through.
Step 103, the upgrade file pass through integrity verification in the case where, to the upgrade file carry out validity
Verifying.
It is to be appreciated that in the case where the integrity verification of the upgrade file passes through namely the upgrade file packet
