Specifically, the automobile central control reads a header file of the software update package and extracts version information of the software update package from the header file. The version information may be data in the form of characters, and for example, the version information may be "v 2".
Step S404, sending the version information to an instrument cluster server so that the instrument cluster server detects the version information and feeds back a signal whether the software upgrading condition is met or not according to the detection result;
the automobile central control sends the version information to the combination instrument server, and the combination instrument server detects the version information after receiving the version information. Specifically, the combination meter server acquires local software version information, compares the version information with the local software version information, and if the version information is later than the update time of the local software version information, the detection result is a condition meeting the software upgrade, and generates a signal meeting the software upgrade condition. If the update time of the version information is earlier than the local software version information or is consistent with the local software version information, the detection result is that the condition of software upgrading is not met, and a signal which does not meet the condition of software upgrading is generated. For example, the version information of the software update package is set as v1, v2 and v3 according to the update time sequence, the version information of the software update package detected by the automobile central control is set as v2, if the local software version information of the combination meter server is set as v1, the update time of the detected version information is later than that of the local software version information, the detection result is that the adjustment of software upgrading is met, and a signal meeting the software upgrading condition is generated; if the local software version information of the combination instrument server is v3, the update time of the detected version information is earlier than that of the local software version information, the detection result is that the adjustment of software upgrading is not met, and a signal meeting the software upgrading condition is generated; and if the local software version information of the combination meter server is v2, the detected version information is consistent with the local software version information, and the detection result is that the adjustment of software upgrading is not met, so that a signal meeting the software upgrading condition is generated. Further, the combination meter server feeds the signal back to the central control of the automobile.
Step S406, if the signal representation meets the software upgrading condition, executing the step of sending an update package downloading instruction to the remote information processor.
And if the signal representation fed back by the combination instrument server received by the central control of the automobile meets the software upgrading condition, the step of sending an update package downloading instruction to the remote information processor is executed. And if the signal representation fed back by the combination instrument server received by the central control of the automobile does not meet the software upgrading condition, stopping the software upgrading process.
