[0070] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two.

[0071] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0072] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0075] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0076] The embodiment of the present application provides a vehicle electronic manual update method, system and electronic device, which are mainly used in vehicle systems. The method can be applied to a terminal, a server, or a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, etc.

[0077] The updating method of the vehicle electronic manual provided in the embodiment of the present application is intended to solve many problems existing in the flexible self-updating process of the vehicle electronic manual resources. By drawing on the combination of incremental update and full update, a new updating method is proposed to improve the updating efficiency and security, reduce costs, and meet user needs.

[0078] At the same time, in order to address the security issues of incremental updates, a local verification mechanism has been introduced to improve the efficiency and security of vehicle electronic manual resource updates. This ensures the standardization and security of vehicle system operations while meeting user needs and optimizing user experience.

[0079] Incremental update technology:

[0080] (1) During each update, only the changed data is transmitted instead of the entire resource package, reducing the amount of data transmitted.

[0081] (2) The cloud generates an incremental update package by comparing the resource differences between the local and cloud versions, and only transmits this part of the update data to the vehicle, reducing update time and network bandwidth consumption.

[0082] (3) A version control system needs to be maintained in the cloud: A version control system (such as Git) can be used in the cloud to manage the versions of incremental packages. Each time a new incremental package is generated, the relevant changes can be submitted and recorded to track the differences between each version.

[0083] (4) Version number management: Assign a unique version number to each incremental package. The semantic versioning rule can be used to facilitate the identification and management of incremental packages of different versions.

[0084] Fully updated technology:

[0085] (1) When the resource structure changes and most of the old resources are abandoned, a full update is required when the resource changes significantly. The entire resource package is transferred to the vehicle at one time to ensure that the vehicle has the latest version of the resources.

[0086] (2) Full update is used as a supplement to incremental update to ensure the integrity and stability of vehicle resources. After the update is successful, old resources are cleared to optimize the storage resources in the vehicle.

[0087] 3. Local authentication mechanism:

[0088] (1) The vehicle uses a local verification mechanism to verify the received update data to ensure the integrity and security of the update package.

[0089] (2) The verification mechanism may include technical means such as hash verification. The same algorithm is used locally and in the cloud to calculate the hash value of the resource package. After the resource package is downloaded, the integrity is verified to prevent data tampering or injection of malicious code.

[0090] Reference Figure 1 , an embodiment of the present invention provides a method for updating a vehicle-mounted electronic manual, the method comprising:

[0091] S101 responds to a resource upgrade request sent by a client, and determines a target vehicle electronic manual according to manual information included in the resource upgrade request;

[0092] S102 obtains the latest resource version information of the target vehicle-mounted electronic manual from the cloud, and compares it with the local resource version information;

[0093] S103 executes updating of the target vehicle electronic manual in different updating modes based on the comparison result and the predefined upgrade planning scheme.

[0094] In the above embodiment, the target vehicle-mounted electronic manual included in step S101 is a vehicle-mounted electronic manual pre-stored in the vehicle-mounted system;

[0095] The vehicle-mounted electronic manual includes: manual information and resource version information;

[0096] The manual information includes: vehicle model information and manual type;

[0097] The manual types include: operation manual, operation and maintenance manual, and spare parts manual.

[0098] In the above embodiment, after receiving and responding to the resource upgrade request sent by the client, the target vehicle electronic manual corresponding to the client's needs can be known through matching according to the vehicle model information and manual type contained in the resource upgrade request;

[0099] In the above embodiment, step S102, obtaining the latest resource version information of the target vehicle-mounted electronic manual from the cloud and comparing it with the local resource version information includes:

[0100] Based on the information comparison between the latest resource version of the target vehicle electronic manual and the local resource version, identifying whether the target vehicle electronic manual for which resource upgrade is requested is the latest resource version;

[0101] If the local resource version is inconsistent with the latest resource version, it means that the local resource version is not the latest resource version; obtain the resource difference between the cloud and local versions, and determine whether the data volume of the resource difference exceeds a preset threshold.

[0102] In the above embodiment, the upgrade planning scheme of step S103 is defined based on resource update operation and maintenance conditions;

[0103] The resource update operation and maintenance conditions include: user privacy, network conditions, and device compatibility factors;

[0104] The upgrade planning scheme includes: updating record maintenance logic, recovery mechanism, and local verification mechanism.

[0105] In the above embodiment, step S103 executes the update of the target vehicle electronic manual in different update modes based on the comparison result and the predefined upgrade plan, including:

[0106] Determine an update mode based on a judgment result of whether the data amount of the resource difference exceeds a preset threshold, and determine the data to be updated according to the update mode;

[0107] The update modes include incremental update mode and full update mode.

[0108] When the data volume of the resource difference does not exceed a preset threshold, determining that the current update mode is an incremental update mode;

[0109] When the data volume of the resource difference exceeds a preset threshold, determining that the current update mode is a full update mode;

[0110] In the incremental update mode, an incremental package is generated based on the resource differences between the cloud and local versions, and a unique version number is assigned to each incremental package; the target vehicle electronic manual is updated based on the incremental package;

[0111] During the update process, the local verification mechanism is called to verify the integrity and transmission status of the incremental package. After the verification is passed, the update record maintenance logic is called to record the detailed information of each update.

[0112] The detailed information of the update includes: unique version number of the incremental package, update time, update content and related change records; the related change records include: resource variables of the latest update of the target vehicle electronic manual compared with the last update;

[0113] In the full update mode, the latest resource version is obtained from the cloud to generate a resource package, the target vehicle electronic manual is updated, and the old resources are cleared after the update is successful.

[0114] It is understandable that the update record maintenance logic helps to track the update history and also facilitates rolling back to the old version when problems occur. In addition, the update record maintenance logic also includes a recovery mechanism to ensure that the system can be restored to a stable state when problems are encountered during the update process. In addition, when pre-defining this logic, factors such as user privacy, network conditions, and device compatibility need to be considered to ensure that the update process is both safe and user-friendly.

[0115] In the above embodiment, the checking of the integrity and transmission status of the incremental packet includes:

[0116] Use SHA-256 hash to verify the data integrity of the incremental package;

[0117] After passing the integrity check, perform signature verification to ensure that the source of the generated incremental package is credible;

[0118] Determine whether the incremental packet is tampered with or damaged during transmission;

[0119] If tampering or damage occurs during the transmission process, error information indicating that the incremental package has been tampered with or damaged during the transmission process is obtained, and the resource package is regenerated and sent;

[0120] If tampering or damage occurs during the update process, the recovery mechanism will be activated to restore the vehicle system to a stable state.

[0121] The method provided in the above embodiment also includes:

[0122] In response to the completion of the update of the target vehicle-mounted electronic manual, confirming the update status, including checking the integrity of the update data and the updated resource version information;

[0123] When the update fails, the error handling process is executed, including trying to roll back the previous resource version. When the rollback fails, the resource that failed to be updated is deleted and obtained again from the cloud when entering next time;

[0124] When the update is successful, the corresponding display interface is loaded to display relevant information.

[0125] In the above embodiment, the loading of the corresponding display interface to display relevant information includes:

[0126] Displaying a first display interface; wherein the first display interface includes the update progress of the target vehicle-mounted electronic manual;

[0127] When the incremental update is detected to be completed, the incremental update of the target vehicle electronic manual is displayed on a second display interface; wherein the second display interface includes the target vehicle electronic manual, the resource version information, the manual information and the incremental update data;

[0128] When the full update is detected to be completed, the full update of the target vehicle electronic manual is displayed on a third display interface; wherein the third display interface includes the target vehicle electronic manual, the resource version information, the manual information and the full update data;

[0129] After displaying the first display interface, the method further includes:

[0130] In response to detecting that the update is not completed, generating an execution log of the update process according to the update of the target vehicle-mounted electronic manual;

[0131] A third display interface is displayed; wherein the third display interface includes the execution log.

[0132] Optionally, based on the above embodiment, the following specific implementation scheme is provided to show how to combine the incremental update and full update technologies to optimize the update process of the vehicle electronic manual resource:

[0133] Full update: The software ROM is upgraded, which involves major changes and requires a full update of the vehicle's electronic manual resources.

[0134] Incremental update: The manual content is large, and the vehicle electronic manual resources are incrementally updated, transmitting only the changed data.

[0135] The process is as follows:

[0136] Full update: The server transmits the full resource package to the vehicle, and the vehicle downloads the full resource package for update.

[0137] Incremental update: The server generates an incremental update package, determines the parts that need to be updated based on the incremental version transmitted by the vehicle, transmits the incremental update package to the vehicle, and the vehicle downloads the incremental resource package for update.

[0138] After the vehicle receives the full package or incremental update package, it is verified through a local verification mechanism to ensure the integrity and security of the updated data.

[0139] After the vehicle is updated, the vehicle electronic manual resources are updated to the latest version.

[0140] In summary, the technical means combining incremental update and full update provided in the above embodiments can realize a fast, efficient and safe vehicle electronic manual resource update process, reduce update costs and improve user experience.

[0141] It can be seen that the above embodiments can solve the following problems:

[0142] 1. Improve update efficiency: By combining incremental updates with full updates, the entire resource package needs to be transmitted for each update, which reduces the network bandwidth and time required for updates and improves update efficiency.

[0143] 2. Improve security: Use local verification mechanisms and digital signatures and other technical means to ensure the integrity and security of updated data and prevent hacker attacks and data tampering.

[0144] 3. Reduce costs: Reduce the amount of data transmission and the time required for updates, save network fees and user power consumption, and reduce update costs.

[0145] 4. Improve user experience: Improve update speed, reduce user waiting time, improve user experience, and reduce the difficulty of maintenance and management.
