5. The method of claim 4, wherein performing the updating of the target in-vehicle electronic manual in the different update modes based on the comparison and the predefined upgrade planning scheme comprises:

Determining an updating mode based on a judging result of whether the data quantity of the resource difference exceeds a preset threshold value, and determining data to be updated according to the updating mode;

the updating modes comprise an increment updating mode and a full updating mode;

When the data quantity of the resource difference does not exceed a preset threshold value, determining that the current updating mode is an incremental updating mode;

When the data quantity of the resource difference exceeds a preset threshold value, determining that the current updating mode is a full updating mode;

In an incremental updating mode, generating an incremental package based on the resource difference of inconsistent cloud and local version, and distributing a unique version number for each incremental package;

In the updating process, a local verification mechanism is called to verify the integrity and the transmission state of the increment packet, and after verification is passed, an updating record maintenance logic is called to record the detailed information of each updating;

The updated detailed information comprises an increment package unique version number, updating time, updating content and related change records, wherein the related change records comprise a resource variable which is updated by the latest time of a target vehicle-mounted electronic manual compared with the last time;

and in the full-volume updating mode, acquiring the latest resource version from the cloud to generate a resource package, updating the target vehicle-mounted electronic manual, and clearing old resources after the updating is successful.

6. The method of claim 5, wherein verifying the integrity and transmission status of the delta packet comprises:

verifying the data integrity of the delta packet using the hash SHA-256;

After passing the integrity check, signature verification is performed to ensure that the source of the generated incremental package is trusted;

judging whether the incremental package is tampered or damaged in the transmission process;

If the situation of tampering or damage occurs in the transmission process, obtaining error information of the situation of tampering or damage of the incremental package in the transmission process, and re-regenerating the resource package and sending the resource package;

if the situation of tampering or damage occurs in the updating process, a recovery mechanism is started, so that the vehicle-mounted system is recovered to a stable state.

7. The method of claim 1, wherein the method further comprises:

The updating condition is confirmed in response to the completion of updating the target vehicle-mounted electronic manual, and the updating condition comprises the steps of checking the integrity of updating data and updated resource version information;

When the updating fails, executing an error processing flow, wherein the error processing flow comprises a resource version before the rollback is tried, when the rollback fails, deleting the resource with the failed updating, and acquiring from the cloud again when entering next time;

and when the updating is successful, loading the corresponding display interface to display the related information.

8. The method of claim 7, wherein loading the corresponding presentation interface display related information comprises:

displaying a first display interface, wherein the first display interface comprises the update progress of the target vehicle-mounted electronic manual;

When the incremental updating is detected to be completed, the incremental updating of the target vehicle-mounted electronic manual is displayed on a second display interface, wherein the second display interface comprises the target vehicle-mounted electronic manual, the resource version information, the manual information and the incremental updating data;

When the completion of the full-volume updating is detected, displaying the full-volume updating of the target vehicle-mounted electronic manual on a third display interface, wherein the third display interface comprises the target vehicle-mounted electronic manual, the resource version information, the manual information and the full-volume updating data;

after the first display interface is displayed, the method further comprises:

Generating an execution log of an update process according to the update of the target vehicle-mounted electronic manual in response to the detection of the incomplete update;

and displaying a third display interface, wherein the third display interface comprises the execution log.

9. An update system for an in-vehicle electronic manual, the system comprising:

The response determining module is used for responding to the resource upgrading request sent by the client and determining a target vehicle-mounted electronic manual according to manual information contained in the resource upgrading request;

the comparison module is used for acquiring the latest resource version information of the target vehicle-mounted electronic manual from the cloud and comparing the latest resource version information with the local resource version information;

And the updating module is used for executing updating aiming at the target vehicle-mounted electronic manual in different updating modes based on the comparison result and a predefined updating planning scheme.

10. An electronic device comprising a memory and a processor, wherein the memory has stored therein a computer program which, when executed by the processor, causes the processor to perform the method steps of any of claims 1-8.
