Description

Technical Field

[0001] This application relates to the field of vehicle networking technology, and more specifically, to a configuration item updating method, apparatus, vehicle, and computer-readable storage medium. Background Technology

[0002] In connected vehicle applications, the cloud typically maintains a set of vehicle electronic control unit (ECU) configuration items. In order to keep the cloud configuration items consistent with the vehicle configuration items, the vehicle's ECU configuration items need to be checked regularly, and the cloud configuration items need to be updated when inconsistencies are found between the cloud and vehicle configuration items.

[0003] However, the current configuration item update efficiency is not high. Therefore, there is an urgent need for a configuration item update method to improve the update efficiency. Summary of the Invention

[0004] This application proposes a configuration item updating method, apparatus, vehicle, and computer-readable storage medium to improve the above-mentioned deficiencies.

[0005] In a first aspect, embodiments of this application provide a configuration item update method, the method comprising:

[0006] In response to a received inspection command from the cloud, the system obtains configuration item blocks corresponding to multiple sub-nodes, each configuration item block including at least one configuration item; it signs all configuration items included in the configuration item block corresponding to each sub-node to obtain a target signature value corresponding to each sub-node; it sends the target signature values ​​corresponding to the multiple sub-nodes to the cloud, so that the cloud compares the target signature value and the verification signature value corresponding to each sub-node to obtain a comparison result corresponding to each sub-node, and generates an update request for the target sub-node based on the target sub-node whose comparison result is inconsistent; the verification signature value corresponding to the sub-node is obtained by signing all configuration items in the backup configuration item block corresponding to the sub-node stored in the cloud; in response to receiving an update request returned by the cloud, the system sends the configuration item block of the target sub-node to the cloud, so that the cloud updates the backup configuration item block of the target sub-node based on the configuration item block of the target sub-node.

[0007] Secondly, embodiments of this application also provide a configuration item updating device, the device comprising:

[0008] The acquisition module is used to acquire the configuration item blocks corresponding to each of the multiple block nodes in response to the inspection command sent by the cloud, and each configuration item block includes at least one configuration item.

[0009] The signature module is used to sign all configuration items included in the configuration item block corresponding to each block node, so as to obtain the target signature value corresponding to each block node.

[0010] The sending module is used to send the target signature values ​​corresponding to each of the plurality of block nodes to the cloud, so that the cloud compares the target signature value and the verification signature value corresponding to each of the block nodes to obtain the comparison result corresponding to each of the block nodes, and generates an update request for the target block node based on the target block node whose comparison result is inconsistent; the verification signature value corresponding to the block node is obtained by signing all the configuration items in the backup configuration item block corresponding to the block node stored in the cloud;

[0011] The determination module is used to send the configuration item blocks of the target block node to the cloud in response to receiving an update request from the cloud, so that the cloud updates the backup configuration item blocks of the target block node according to the configuration item blocks of the target block node.

[0012] Thirdly, embodiments of this application also provide a vehicle, characterized in that the vehicle includes: one or more processors; a memory; one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs are configured to perform the above-described methods.

[0014] This application provides a configuration item update method, apparatus, vehicle, and computer-readable storage medium. In this application, in response to a received inspection command sent from the cloud, configuration item blocks corresponding to multiple block nodes are obtained. All configuration items included in the configuration item block corresponding to each block node are signed to obtain a target signature value corresponding to each block node. The cloud compares the target signature value corresponding to each block node with the verification signature value. The vehicle only needs to send the configuration item blocks of the block nodes whose comparison results are inconsistent to the cloud to update the corresponding backup configuration item blocks in the cloud. It does not need to send all configuration item blocks to the cloud to update all backup configuration item blocks, thus saving cloud service bandwidth and improving configuration item update efficiency.

[0031] Please see Figure 2 , Figure 2 A flowchart of a configuration item update method according to an embodiment of this application is shown, for a vehicle, the method comprising:

[0032] S201. In response to the inspection command sent by the cloud, obtain the configuration item blocks corresponding to each of the multiple block nodes.

[0033] Each configuration item block includes at least one configuration item. A configuration item refers to all items included in the configuration management scope, and can be a name, software version, hardware number, etc. Inspection commands are used by vehicles to report the target signature values ​​of multiple block nodes. Inspection commands can be periodically sent to vehicles from the cloud.

[0034] In some implementations, the number of block nodes can be determined based on the number of configuration items. After determining the block nodes, multiple configuration items can be divided into blocks corresponding to each node based on the block nodes. The block nodes can be virtual nodes.

[0035] S202. Sign all configuration items included in the configuration item block corresponding to each block node to obtain the target signature value corresponding to each block node.

[0036] The target signature value is the value obtained by signing the information of all configuration items included in the configuration item block corresponding to each block node. In other words, it is the value obtained by signing the did data stored in the configuration item block corresponding to each block node. It is used as the anti-tampering identifier of the current configuration item block and is equivalent to the digest of the configuration item block content. The target signature value can be the hash value of the information of all configuration items included in each configuration item block. The data identifier did represents an object (e.g., intake valve position) or a collection of multiple objects.

[0037] S203. Send the target signature values ​​corresponding to each of the multiple block nodes to the cloud so that the cloud can compare the target signature value and the verification signature value corresponding to each block node, obtain the comparison result corresponding to each block node, and generate an update request for the target block node for inconsistent target block nodes based on the comparison result.

[0038] The verification signature value corresponding to the block node is obtained by signing all the configuration items in the backup configuration item block corresponding to the block node stored in the cloud.

[0039] The verification signature value is the value obtained by signing the information of all configuration items included in the backup configuration item block corresponding to each block node in the cloud. In other words, it is the value obtained by signing the did data stored in the backup configuration item block corresponding to each block node in the cloud. It is used as the anti-tampering identifier of the current backup configuration item block, which is equivalent to the digest of the backup configuration item block content. The verification signature value can be the hash value of the information of all configuration items included in each backup configuration item block.

[0040] In some implementations, the cloud-based backup configuration item blocks correspond one-to-one with the vehicle's configuration item blocks, and the configuration items included in the corresponding vehicle configuration item blocks also correspond one-to-one with those included in the cloud-based backup configuration item blocks. The cloud-based backup configuration item blocks and the vehicle's configuration item blocks follow the same block segmentation rules. Initially, the vehicle's configuration item blocks and the cloud-based backup configuration item blocks are completely identical, and the configuration items included in the vehicle's configuration item blocks and the cloud-based backup configuration item blocks are also completely identical.

[0041] The target signature value of the vehicle's configuration item block represents the vehicle's configuration item block and the corresponding block node. The verification signature value of the cloud-based configuration item block represents the cloud-based backup configuration item block and the corresponding block node. By comparing the target signature value and the verification signature value, it can be determined whether the configuration item block and its corresponding backup configuration item block are consistent, that is, whether the content of the vehicle's configuration item block has changed.

[0042] If there are target block nodes with inconsistent comparison results, the cloud can generate an update request for the target block node based on the target block node with inconsistent comparison results. The content of the update request can be the content of the configuration item block corresponding to the target block node, or it can be an identifier that can represent the target block node.

[0043] If no target block node with inconsistent comparison results exists, the cloud may not send any requests to the vehicle, and the vehicle may wait to receive the next inspection instruction from the cloud. Alternatively, the cloud may send relevant information about consistent comparison results to the vehicle.

[0044] S204. In response to receiving an update request from the cloud, the configuration item blocks of the target block node are sent to the cloud so that the cloud updates the backup configuration item blocks of the target block node according to the configuration item blocks of the target block node.

[0045] In some implementations, updating the backup configuration item block of the target block node based on the configuration item block of the target block node can be achieved by having the cloud replace each configuration item in the backup configuration item block of the target block node with each configuration item in the configuration item block of the target block node, or by having the cloud replace inconsistent configuration items in the backup configuration item block of the target block node with the configuration items in the configuration item block of the target block node that correspond to the inconsistent configuration items.

[0046] In some implementations, in response to the activation operation of the service to be activated, an activation request is sent to the cloud, so that the cloud compares the configuration items to be verified corresponding to the service to be activated with the configuration items corresponding to the configuration items to be verified in the updated configuration item set, obtains the activation comparison result, and obtains an activation instruction if the activation comparison result is consistent; the updated configuration item set includes the updated backup configuration item block corresponding to the target block node and the backup configuration item blocks corresponding to the other block nodes excluding the target block node among the multiple block nodes; in response to the activation instruction returned by the cloud, the service to be activated is activated.

[0047] The service to be activated can be software to be activated, or it can be a function to be activated in already activated software, such as intelligent driving function.

[0048] like Figure 3 As shown, each service to be activated corresponds to multiple electronic control units (ECUs), and each ECU corresponds to multiple configuration items.

[0049] In some implementations, the cloud can obtain an activation comparison result by comparing the configuration item to be verified corresponding to the service to be activated with the configuration item corresponding to the configuration item in the updated configuration item set, and obtain an activation instruction if the activation comparison result is consistent. This can be achieved by the cloud searching for the configuration item corresponding to the service to be activated in the cloud, comparing the configuration item corresponding to the service to be activated with the configuration item corresponding to the configuration item in the cloud, obtaining an activation comparison result, and obtaining an activation instruction if the activation comparison result is consistent.

[0050] Specifically, finding the configuration item corresponding to the unverified configuration item for the service to be activated based on the activation request can be done by finding the identifier of the configuration item corresponding to the identifier of the unverified configuration item. The configuration item corresponding to the identifier of the configuration item corresponding to the identifier is the configuration item corresponding to the unverified configuration item. A consistent activation comparison result means that the unverified configuration item for the service to be activated and its corresponding configuration item are consistent.

[0051] In this embodiment, in response to the inspection command sent by the cloud, the configuration item blocks corresponding to each of the multiple block nodes are obtained. All configuration items included in the configuration item block corresponding to each block node are signed to obtain the target signature value corresponding to each block node. The cloud compares the target signature value and the verification signature value corresponding to each block node. The vehicle only needs to send the configuration item blocks of the block nodes whose comparison results are inconsistent to the cloud to update the corresponding backup configuration item blocks in the cloud. It is not necessary to send all configuration item blocks to the cloud to update all backup configuration item blocks, which saves cloud service bandwidth and improves configuration item update efficiency.

[0052] Please see Figure 4 , Figure 4 A flowchart of a configuration item update method according to another embodiment of this application is shown, for a vehicle, the method comprising:

[0053] S301. Obtain multiple target electronic control units in the vehicle and the configuration items corresponding to each target electronic control unit.

[0054] The Electronic Control Unit (ECU) is a control device composed of integrated circuits used to perform a series of functions such as data analysis, processing, and transmission. It is also known as an electronic control unit, automotive electronic control unit, integrated circuit control unit, or multiplexer. The target ECU is an ECU selected from all the ECUs in the vehicle based on business requirements. That is, the target ECU can be all the ECUs in the vehicle, or it can be a subset of them. When business requirements change, the target ECU may also change accordingly.

[0055] like Figure 5 As shown, each vehicle corresponds to multiple electronic control units (ECUs), and each ECU corresponds to multiple configuration items.

[0056] S302. Determine the configuration item hash value corresponding to each configuration item for each target electronic control unit.

[0057] Hash, also known as hashing, refers to transforming an input of arbitrary length (also called a pre-image) into a fixed-length output using a hash algorithm. This output is the hash value. Hash values ​​compress messages or data into digests, reducing the data size and fixing the data format.

[0058] In some implementations, S302 may include: for each target electronic control unit, concatenating the identifier of the target electronic control unit and the identifier of each configuration item corresponding to the target electronic control unit to obtain a concatenated identifier corresponding to each configuration item corresponding to the target electronic control unit; performing a hash operation on the concatenated identifier corresponding to each configuration item corresponding to each target electronic control unit to obtain a configuration item hash value corresponding to each configuration item corresponding to each target electronic control unit.

[0059] The identifier of the target electronic control unit can be its ID, and the identifier of a configuration item under the target electronic control unit can be its ID. For example, if the ID of a target electronic control unit is ECU_ID_2, and the ID of a configuration item under that target electronic control unit is ID_3, then the concatenated identifier corresponding to that configuration item under the target electronic control unit is ECU_ID_2+ID_3.

[0060] S303, Determine multiple block nodes.

[0061] In some implementations, S304 may include: determining multiple block nodes based on the number of multiple target electronic control units and the number of configuration items corresponding to each target electronic control unit.

[0062] In some implementations, multiple sub-nodes can be determined by setting a threshold for the number of configuration items corresponding to the target electronic control unit for each sub-node, and then calculating the quotient of the total number of configuration items corresponding to multiple target electronic control units and the threshold. Alternatively, multiple sub-nodes can be obtained by evenly distributing the configuration items corresponding to multiple target electronic control units.

[0063] S304. Based on the hash value of each block node and the configuration item hash value of each configuration item, the configuration items corresponding to multiple target electronic control units are divided into configuration item blocks corresponding to each block node.

[0064] After obtaining the hash values ​​of the block nodes and the configuration item hash values ​​of each configuration item, these hash values ​​are mapped onto the same hash ring. Based on the hash ring, the configuration items corresponding to multiple target electronic control units can be divided into multiple configuration item blocks corresponding to each block node. The number of configuration items included in each configuration item block can be the same or different. The hash ring is a virtual ring that organizes the entire hash value space in a clockwise direction.

[0065] In some implementations, S304 may include: determining the label values ​​of each of the multiple block nodes; performing a hash operation on the label value of each block node to obtain the hash value of each block node; obtaining the configuration item hash value that matches the hash value of each block node as the associated configuration item hash value corresponding to each block node; obtaining and summarizing the configuration items corresponding to each associated configuration item hash value of each block node to obtain the configuration item block corresponding to each block node.

[0066] The label value is a randomly assigned value used to calculate the hash value of the block node and map it to the hash ring. Each block node corresponds to a label value, each block node corresponds to a configuration item block, and each label value corresponds to a configuration item block.

[0067] In some implementations, obtaining the configuration item hash value that matches the hash value of each block node, and using it as the associated configuration item hash value for each block node, may include: constructing an initial hash ring based on the hash value of each block node; mapping each configuration item hash value to the initial hash ring to obtain a hash ring; for each block node, obtaining the configuration item hash value on the hash ring that lies between the block node and its corresponding target adjacent block node, and using it as the associated configuration item hash value for the block node. The target adjacent block node refers to the block node adjacent to the block node in the target direction. The target direction can be clockwise.

[0068] In some implementations, a consistent hashing algorithm can be used to map the hash value of the block node to the hash values ​​of multiple configuration items on the same hash ring. The configuration item hash value is then matched with the hash value of the block node in the target direction on the hash ring to obtain the associated configuration item hash value corresponding to the block node.

[0069] Among them, the consistent hashing algorithm transforms the ordinary linear hash space into a ring-shaped hash space, where each cache space is a node on the ring, and data is generally stored in the first node on the ring found in a clockwise direction.

[0070] like Figure 6 As shown, Figure 6 The circle in the image is a hash ring. Figure 4 The circles on the hash ring represent block nodes. Figure 6 The triangles on the hash ring represent configuration items.

[0071] After obtaining the hash value of the associated configuration item corresponding to the block node, the configuration item corresponding to each of the hash values ​​of the associated configuration items of each block node is summarized to obtain the configuration item block corresponding to each block node.

[0072] If a new target electronic control unit is added to the multiple target electronic control units in the vehicle, multiple block nodes can be re-determined based on the number of the new target electronic control units and the number of configuration items corresponding to each target electronic control unit, the hash ring can be reconstructed, and the configuration item blocks can be re-determined.

[0073] In other implementations, if a new target electronic control unit is added to the multiple target electronic control units in the vehicle, the configuration item hash value corresponding to the new target electronic control unit can be directly mapped to the original hash ring, and the corresponding configuration item block can be updated.

[0074] If a target electronic control unit is removed from multiple target electronic control units in a vehicle, multiple block nodes can be re-determined based on the number of removed target electronic control units and the number of configuration items corresponding to each target electronic control unit, the hash ring can be reconstructed, and the configuration item blocks can be re-determined.

[0075] In other implementations, if a target electronic control unit is removed from multiple target electronic control units in a vehicle, the configuration item hash value of the removed target electronic control unit can be directly deleted from the original hash ring, and the corresponding configuration item block can be updated.

[0076] In addition, while the vehicle is building the hash ring, the cloud is also building the cloud hash ring simultaneously. The method for building the cloud hash ring in the cloud is the same as that in the vehicle. When the vehicle rebuilds or updates the hash ring, the cloud also rebuilds or updates the cloud hash ring simultaneously.

[0077] S305. In response to the inspection command sent by the cloud, obtain the configuration item blocks corresponding to each of the multiple block nodes, each configuration item block including at least one configuration item; sign all the configuration items included in the configuration item block corresponding to each block node to obtain the target signature value corresponding to each block node.

[0078] S306. Send the target signature values ​​corresponding to each of the multiple block nodes to the cloud so that the cloud can compare the target signature value and the verification signature value corresponding to each block node, obtain the comparison result corresponding to each block node, and generate an update request for the target block node for inconsistent target block nodes based on the comparison result.

[0079] The descriptions of S305-S306 are the same as those of S201-S203 above, and will not be repeated here.

[0080] S307. In response to receiving an update request from the cloud, the configuration item blocks of the target block node are sent to the cloud so that the cloud updates the backup configuration item blocks of the target block node according to the configuration item blocks of the target block node.

[0081] The update request returned by the cloud can be the tag value of the target block node.

[0082] In some implementations, in response to receiving the tag value of the target block node returned by the cloud, the configuration item block corresponding to the target block node is searched in the hash ring according to the tag value, and the configuration item block of the target block node is sent to the cloud so that the cloud updates the backup configuration item block of the target block node according to the configuration item block of the target block node.

[0083] The other descriptions of S306 are the same as those in S204 above, and will not be repeated here.

[0084] The configuration item update process in this embodiment is as follows: Figure 7 As shown, the cloud and vehicle synchronously calculate the number of block nodes; assign label values ​​to block nodes; calculate the hash value of the label value and map the hash value of the block node onto a hash ring; calculate the configuration item hash value of the configuration item and map the configuration item hash value onto a hash ring; determine the configuration item block based on the hash value of the block node on the hash ring and the configuration item hash value; calculate the target signature value and verification signature value corresponding to each block node; the vehicle reports the target signature value corresponding to the block node; the cloud compares the target signature value and the verification signature value and filters out the target signature values ​​that are inconsistent with the verification signature value; the vehicle reports the configuration item block corresponding to the inconsistent target signature value; the cloud updates the corresponding backup configuration item block based on the configuration item block corresponding to the inconsistent signature value reported by the vehicle.

[0085] In this embodiment, multiple target electronic control units (ECUs) in the vehicle and their corresponding configuration items are obtained. The hash value of each configuration item corresponding to each target ECU is determined; the hash value is equivalent to a summary of the configuration item. Multiple block nodes are identified. Based on the hash value of each block node and the configuration item hash value of each configuration item, the configuration items corresponding to the multiple target ECUs are divided into configuration item blocks corresponding to each block node, improving the efficiency of configuration item division. Simultaneously, the vehicle only needs to send the configuration item blocks of block nodes where the comparison results are inconsistent to the cloud to update the corresponding backup configuration item blocks in the cloud. It does not need to send all configuration item blocks to the cloud to update all backup configuration item blocks, saving cloud service bandwidth and improving configuration item update efficiency.

[0086] See appendix Figure 8 , Figure 8 This illustration shows a structural block diagram of a configuration item updating device according to an embodiment of this application, for a vehicle. The device 400 includes:
