[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0028] Figure 1 A flowchart of a method for updating routing rules provided in an embodiment of the present invention is applicable to the scenario of updating routing rules of a car. The method can be executed by a routing rule updating device, which can be implemented by software and / or hardware and integrated into a computer device with application development function.

[0029] like Figure 1 As shown, the routing rule updating method of this embodiment includes the following steps:

[0030] S110. After the gateway of the target vehicle is powered on, determine the preset routing rule storage area in an activated state, and obtain the routing rule data to be verified in the preset routing rule storage area in an activated state.

[0031] In this embodiment, an independent preset routing rule storage area is designed inside the gateway, which is only used to store routing rules. The routing rules can be a routing table binary file. The working state of the preset routing rule storage area can include two states: activated and inactivated, which can be determined by an identifier corresponding to the working state. After the gateway of the target vehicle is powered on, the preset routing rule storage area in the activated state is automatically determined, and the routing rule data in the preset routing rule storage area in the activated state is used as the routing rule data to be verified. The routing rule data to be verified cannot be directly read into the random access memory (RAM, Random Access Memory), nor can it be imported into the routing function module for operation after parsing the random access memory, but must be verified first to determine that it is the latest routing rule data.

[0032] S120: Based on a preset verification algorithm, a verification calculation is performed on the routing rule data to be verified to obtain a corresponding characteristic value to be verified.

[0033] The preset verification algorithm may be a hash algorithm, which may include but is not limited to MD5 (Message Digest Algorithm 5, message digest algorithm fifth version) and SHA-256 (Secure Hash Algorithm 256-bit secure hash algorithm 256-bit) and the like.

[0034] The routing rule data to be verified is verified and calculated to obtain the corresponding characteristic value to be verified.

[0035] The routing rule data to be verified is calculated into a corresponding feature value to be verified through MD5, and the feature value to be verified can be a 32-bit hexadecimal number. The routing rule data to be verified is calculated into a corresponding feature value to be verified through SHA-256, and the feature value to be verified can be a 256-bit hash value.

[0036] S130, obtaining the latest rule verification feature value from the cloud, and when the latest rule verification feature value is different from the feature value to be verified, obtaining the latest routing rule data corresponding to the latest rule verification feature value from the cloud to complete the routing rule update.

[0037] The latest rule verification characteristic value is determined by verifying and calculating the latest routing rule data through a preset verification algorithm.

[0038] When the routing rules need to be updated, the routing rule designer in the backend of the cloud TSP (Telematics Service Provider, the server-side system of the telematics service provider) uploads the latest routing rule data after the change and the latest rule verification feature value corresponding to the latest routing rule data to the backend of the cloud TSP. The latest rule verification feature value is determined by verifying and calculating the latest routing rule data using the same preset verification algorithm as the one used to calculate the feature value to be verified.

[0039] The routing rule data is synchronized to the cloud TSP background, and written into the routing rule storage area after verification. The next time the gateway of the target vehicle is powered on, it will read and parse the latest updated routing rule data in a dynamic loading manner, and realize the function of the latest routing rule data.

[0040] When updating the routing rules in this embodiment, it is only necessary to remotely upload the new routing rule data, i.e., the routing table file, to the cloud backend. No other operations are required, and the operation process is simple and convenient. The routing rule data is stored and loaded independently, and other functions of the gateway will not be affected. Compared with OTA (Over-the-Air Technology) upgrades, the upgrade content only includes routing rules, the upgrade file is small, and there is no need to issue upgrade tasks. The gateway controller actively queries and synchronizes the background.

[0041] The technical solution of this embodiment is to determine the preset routing rule storage area in an activated state after the gateway of the target vehicle is powered on, and obtain the routing rule data to be verified in the preset routing rule storage area in an activated state; based on the preset verification algorithm, verify and calculate the routing rule data to be verified to obtain the corresponding characteristic value to be verified; obtain the latest rule verification characteristic value in the cloud, and when the latest rule verification characteristic value is different from the characteristic value to be verified, obtain the latest routing rule data corresponding to the latest rule verification characteristic value from the cloud to complete the routing rule update; wherein, the latest rule verification characteristic value is determined by verifying and calculating the latest routing rule data through the preset verification algorithm. The technical solution of the embodiment of the present invention solves the problems of low efficiency and long time consumption of routing rule update in the prior art, and can automatically determine whether to update the routing rules after power-on, and remotely configure and update according to the cloud data when the routing rules need to be updated, thereby improving the efficiency and reliability of routing rule download.

[0042] Figure 2A flowchart of a routing rule updating method provided in an embodiment of the present invention, this embodiment and the routing rule updating method in the above embodiment belong to the same inventive concept, and further describes the process of obtaining the latest routing rule data corresponding to the latest rule verification feature value from the cloud to complete the routing rule update. The method can be executed by a routing rule updating device, which can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0043] like Figure 2 As shown, the process of obtaining the client log content in the routing rule updating method of this embodiment includes the following steps:

[0044] S210: After the gateway of the target vehicle is powered on, determine the preset routing rule storage area in an activated state, and obtain the routing rule data to be verified in the preset routing rule storage area in an activated state.

[0045] S220: Based on a preset verification algorithm, a verification calculation is performed on the routing rule data to be verified to obtain a corresponding characteristic value to be verified.

[0046] S230, obtaining the latest rule verification feature value from the cloud, and when the latest rule verification feature value is different from the feature value to be verified, downloading the latest routing rule data from the cloud.

[0047] S240: When the download is successful, the latest routing rule data is stored in a preset routing rule storage area that is in an inactivated state.

[0048] The latest routing rule data is stored in a preset routing rule storage area in an inactive state, and after being read into the RAM, the latest routing rule data is parsed and run in the routing function module.

[0049] In an optional implementation, the latest routing rule data is stored in a preset routing rule storage area in an inactivated state. The to-be-confirmed rule verification characteristic value corresponding to the latest routing rule data may be calculated according to a preset verification algorithm. When the latest rule verification characteristic value and the to-be-confirmed rule verification characteristic value are the same, the latest routing rule data is stored in a preset routing rule storage area in an inactivated state.

[0050] It can be understood that in order to ensure that the downloaded routing rule data is exactly the same as the latest routing rule data, the check feature value of the to-be-confirmed rule corresponding to the latest routing rule data is calculated according to the preset check algorithm. If the check feature value of the latest rule is the same as the check feature value of the to-be-confirmed rule, it means that the routing rule data is exactly the same as the latest routing rule data, and the latest routing rule data is stored in the preset routing rule storage area in an inactive state. If they are not the same, the latest routing rule data is downloaded again.

[0051] S250: Change the working state of the preset routing rule storage area in an inactivated state to an activated state.

[0052] S260: Change the working state of the preset routing rule storage area in the activated state to the inactivated state.

[0053] like Figure 3 As shown, the gateway and the cloud TSP backend can communicate through the vehicle terminal T-BOX. In the preset chip inside the gateway, such as the preset Flash (non-volatile storage chip), at least two independent preset routing rule storage areas are allocated for routing rule data. Figure 3 The preset routing rule storage area A and the preset routing rule storage area B are used to prevent special circumstances from occurring when updating and writing routing rule data, such as unstable power supply, which may cause routing rule data to be lost and the gateway cannot work properly. In these two storage areas, there will be flags indicating the working status of the preset routing rule storage area. The working status may include an activated state and an inactivated state. The activated state corresponds to flag 1, and the inactivated state corresponds to flag 2. It is used to indicate whether the routing rule data stored in this storage area is activated. When updating the routing rules, the latest updated routing rule data will be written to the inactivated storage area, and the flag position will be set to 1, and the flag position of the original activated storage area will be set to 0. Each time the gateway is powered on, the routing rule data with the activation flag bit set to 1, that is, the routing table partition data, will be read into the RAM, and after parsing, it will be imported into the routing function module of the gateway for operation.

[0054] In an optional implementation, when the download is unsuccessful, the working state of the preset routing rule storage area is not changed.

[0055] In the case of unsuccessful download, such as when the network is unstable during the download process, or when the gateway is powered off, the original working state of the preset routing rule storage area is maintained without change. Thus, after the network is restored or the gateway is powered on, the download process is continued. In addition, when the network instability lasts for more than a preset time threshold, the routing rule data stored in the preset routing rule storage area in the activated state can be directly read and run.

[0056] In an optional implementation, the number of preset routing rule storage areas is at least two, including at least one preset routing rule storage area in an activated state and at least one preset routing rule storage area in an inactivated state.

[0057] The technical solution of this embodiment is to determine the preset routing rule storage area in the activated state after the gateway of the target vehicle is powered on, and obtain the routing rule data to be verified in the preset routing rule storage area in the activated state; based on the preset verification algorithm, perform verification calculation on the routing rule data to be verified to obtain the corresponding characteristic value to be verified; obtain the latest rule verification characteristic value in the cloud, and when the latest rule verification characteristic value is different from the characteristic value to be verified, download the latest routing rule data in the cloud; if the download is successful, store the latest routing rule data in the preset routing rule storage area in the inactivated state; change the working state of the preset routing rule storage area in the inactivated state to the activated state. The technical solution of the embodiment of the present invention solves the problems of low efficiency and long time consumption of routing rule update in the prior art, can automatically determine whether to update routing rules after power-on, and remotely configure and update according to cloud data when routing rules need to be updated, store routing rule information through an independent routing rule storage area, and update routing rules by changing the working state, so as to avoid the influence of update failure on routing function, and improve the efficiency and reliability of routing rule download.

[0060] Among them, the routing data acquisition module 310 is used to determine the preset routing rule storage area in the activated state after the gateway of the target vehicle is powered on, and obtain the routing rule data to be verified in the preset routing rule storage area in the activated state; the characteristic value calculation module 320 to be verified is used to verify and calculate the routing rule data to be verified based on the preset verification algorithm to obtain the corresponding characteristic value to be verified; the routing rule update module 330 is used to obtain the latest rule verification characteristic value from the cloud, and when the latest rule verification characteristic value is different from the characteristic value to be verified, obtain the latest routing rule data corresponding to the latest rule verification characteristic value from the cloud to complete the routing rule update; wherein, the latest rule verification characteristic value is determined by verifying and calculating the latest routing rule data through the preset verification algorithm.

The technical solution of the embodiment of the present invention solves the problems of low efficiency and long time consumption of routing rule update in the prior art, and can automatically determine whether to update the routing rules after power-on, and remotely configure and update according to the cloud data when the routing rules need to be updated, thereby improving the efficiency and reliability of routing rule download.

[0062] In an optional implementation, the routing rule updating module 330 is specifically used for:
