Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle control technology, and more specifically, to a communication enhancement method, apparatus, new energy vehicle, and electronic device based on SOME / IP services. Background Technology
[0002] In existing vehicular networks, service communication based on the service-oriented Ethernet communication protocol (Scalableservice-Oriented Middleware over IP, SOME / IP) is widely used for service discovery, event publishing, and remote invocation. However, due to the lack of deterministic transmission capabilities in traditional Ethernet, SOME / IP services suffer from the following problems in terms of real-time performance and bandwidth guarantees: The granularity of service classification is coarse. Existing solutions typically classify traffic based solely on priority labels, without considering the time-sensitive nature of Time-Sensitive Networking (TSN). This results in high-critical services (such as braking commands) sharing bandwidth with low-priority traffic (such as entertainment data), easily causing latency jitter. Static bandwidth allocation is inefficient. Traditional TSN configurations rely on offline scheduling tables and cannot dynamically adapt to the addition or removal of service instances (such as adding ADAS sensors). When network load changes abruptly, static reservations lead to insufficient bandwidth utilization. Summary of the Invention
[0003] The purpose of this application is to provide a communication enhancement method, device, new energy vehicle, and electronic device based on SOME / IP services, which can improve the granularity of SOME / IP service classification, separate bandwidth resources used for critical services, avoid anomalies caused by shared bandwidth, improve bandwidth allocation efficiency, and make adaptive adjustments when new service instances are added, thereby improving bandwidth utilization.
[0004] In a first aspect, embodiments of this application provide a communication enhancement method based on SOME / IP services, the method comprising: Retrieve the communication messages corresponding to the SOME / IP service; The SOME / IP services are classified according to the communication messages to obtain service categories; The service category is mapped to the TSN priority to obtain the TSN parameter of the SOME / IP service; A hybrid bandwidth allocation strategy is constructed based on the TSN parameters; Bandwidth resources are allocated according to the hybrid bandwidth allocation strategy to enhance communication.
[0005] In the above implementation process, more granular classification of SOME / IP services and mapping them with TSN priorities can improve the granularity of SOME / IP service classification, separate bandwidth resources used for critical services, avoid anomalies caused by shared bandwidth, improve bandwidth allocation efficiency, and make adaptive adjustments when new service instances are added to improve bandwidth utilization.
[0006] Further, the step of classifying the SOME / IP services based on the communication messages to obtain service categories includes: The priority corresponding to the SOME / IP service is obtained based on the communication message; The real-time category is determined based on the latency requirements of the SOME / IP service. The periodic categories are obtained based on the data characteristics of the SOME / IP service; The service category is obtained based on the priority, real-time category, and periodicity category.
[0007] In the above implementation process, the service category is obtained according to the priority, real-time category and periodic category of the SOME / IP service. The SOME / IP service can be classified from multiple perspectives to achieve a more refined classification.
[0008] Further, the step of obtaining the priority corresponding to the SOME / IP service based on the communication message includes: Extract the functional safety level from the communication message; The SOME / IP services are categorized according to the functional safety level to obtain the priority.
[0009] In the above implementation process, classifying SOME / IP services according to their functional safety levels can clarify their importance and security level, providing a basis for better implementation of SOME / IP services.
[0010] Further, the step of obtaining the real-time category based on the latency requirements of the SOME / IP service includes: Obtain the end-to-end latency of the SOME / IP server; The real-time category is obtained by comparing the delay time with a delay threshold.
[0011] In the above implementation process, by comparing the latency of SOME / IP services with the latency threshold, the time-based priority of SOME / IP services can be clearly defined, providing data support for the rational planning of bandwidth resource allocation for SOME / IP services.
[0012] Further, the step of obtaining periodic categories based on the data characteristics of the SOME / IP service includes: Obtain the data characteristics of the SOME / IP service; If the data feature is sensor data, then the periodicity category is determined to be periodic; If the data feature is a diagnostic request, the periodicity category is determined to be non-periodic.
[0013] In the above implementation process, by determining the periodic categories based on the data characteristics of SOME / IP services, the data characteristics of SOME / IP services can be periodically classified, the characteristics of each type of data can be clarified, and the classification efficiency of SOME / IP services can be improved.
[0014] Further, the step of mapping the service category to the TSN priority to obtain the TSN parameters of the SOME / IP service includes: Obtain the traffic category of the TSN; The TSN priority is determined based on the traffic category; The TSN priority is mapped to the service category to obtain the TSN parameters of the SOME / IP service.
[0015] In the above implementation process, by mapping TSN priority to service category, the detailed classification of SOME / IP services can be mapped to TSN priority, clearly defining the TSN priority of each SOME / IP service.
[0016] Furthermore, the step of constructing a hybrid bandwidth allocation strategy based on the TSN parameters includes: Configure extended interface information according to the TSN parameters; Construct a service instance based on the interface information; The hybrid bandwidth allocation strategy is constructed based on the service instance.
[0017] In the above implementation process, by configuring extended interface information and building service instances according to TSN parameters, and by constructing specific hybrid bandwidth allocation strategies, reasonable bandwidth resource allocation for SOME / IP services can be achieved, reducing the waste of bandwidth resources.
[0018] Further, the step of constructing the hybrid bandwidth allocation strategy based on the service instance includes: Determine whether the service instance is a newly added service instance; If so, the hybrid bandwidth allocation strategy is determined to allow services with higher TSN priority to preempt bandwidth resources with lower TSN priority; If not, when the traffic category in the service instance is the first traffic category or the second traffic category, the hybrid bandwidth allocation strategy is determined to reserve bandwidth resources of the first resource threshold and use the remaining bandwidth resources of the second resource threshold as dynamic contribution resources; If not, when the traffic category in the service instance is the third or fourth traffic category, a pre-set mixed bandwidth allocation strategy is adopted.
[0019] In the above implementation process, different bandwidth allocations are made according to different service instances, which can improve the utilization of bandwidth resources and enhance the communication capabilities of SOME / IP services.

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation on the range.

Detailed Implementation
[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.
[0032] Existing technologies do not take into account the time-sensitive nature of TSN when allocating bandwidth resources, resulting in high-critical services and low-priority traffic sharing bandwidth, which can easily cause latency jitter. Static bandwidth allocation is inefficient, and traditional TSN configurations rely on offline scheduling tables, which cannot dynamically adapt to the increase or decrease of service instances. When network load changes suddenly, static reservation leads to insufficient bandwidth utilization.
[0033] This application enables fine-grained service classification and mapping of these classifications to TSN traffic, achieving dynamic hierarchical management of SOME / IP services and precise binding with TSN time-sensitive queues. By combining static reservation with dynamic negotiation, it improves bandwidth resource utilization.
[0034] Example 1 Figure 1 This is a flowchart illustrating a communication enhancement method based on SOME / IP services provided in an embodiment of this application. Figure 1 As shown, the method includes: S1, obtain the communication message corresponding to the SOME / IP service; S2, classify SOME / IP services according to communication messages to obtain service categories; S3 maps the service category to the TSN priority to obtain the TSN parameters of the SOME / IP service; S4, Construct a hybrid bandwidth allocation strategy based on TSN parameters; S5 allocates bandwidth resources according to a hybrid bandwidth allocation strategy to enhance communication.
[0035] In the above implementation process, more granular classification of SOME / IP services and mapping them with TSN priorities can improve the granularity of SOME / IP service classification, separate bandwidth resources used for critical services, avoid anomalies caused by shared bandwidth, improve bandwidth allocation efficiency, and make adaptive adjustments when new service instances are added to improve bandwidth utilization.
[0036] Furthermore, S2 includes: Obtain the priority corresponding to the SOME / IP service based on the communication message; Obtain the real-time category based on the latency requirements of the SOME / IP service; Periodic categories are obtained based on the data characteristics of SOME / IP services; Service categories are determined based on priority, real-time nature, and periodicity.
[0037] In the above implementation process, the service category is obtained according to the priority, real-time category and periodic category of the SOME / IP service. The SOME / IP service can be classified from multiple perspectives to achieve a more refined classification.
[0038] This application implements service classification from three dimensions: criticality, real-time performance, and data characteristics.
[0039] Furthermore, the steps for obtaining the priority corresponding to the SOME / IP service based on the communication message include: Extract the functional safety level from the communication message; SOME / IP services are categorized according to their functional safety levels to determine their priority.
[0040] In the above implementation process, classifying SOME / IP services according to their functional safety levels can clarify their importance and security level, providing a basis for better implementation of SOME / IP services.
[0041] Based on functional safety levels, they are divided into ASIL-A to ASIL-D. For example, ASIL-D services are braking and steering control, which are classified as the highest priority. The priority is ASIL-D > ASIL-C > ASIL-B > ASIL-A. ASIL-A services are camera and radar data acquisition, ASIL-B services are powertrain status, and ASIL-C services are infotainment.
[0042] Furthermore, the steps for obtaining the real-time category based on the latency requirements of the SOME / IP service include: Get the end-to-end latency of the SOME / IP server; The real-time category is obtained by comparing the delay time with the delay threshold.
[0043] In the above implementation process, by comparing the latency of SOME / IP services with the latency threshold, the time-based priority of SOME / IP services can be clearly defined, providing data support for the rational planning of bandwidth resource allocation for SOME / IP services.
[0044] The delay threshold is divided into three different thresholds. In this embodiment, the first delay threshold is 1ms, the second delay threshold is 5ms, and the third delay threshold is 10ms.
[0045] Furthermore, the step of obtaining periodic categories based on the data characteristics of the SOME / IP service includes: Obtain the data characteristics of SOME / IP services; If the data characteristics are sensor data, then the periodicity category is determined to be periodic; If the data feature is a diagnostic request, determine the periodicity category as non-periodic.
[0046] In the above implementation process, by determining the periodic categories based on the data characteristics of SOME / IP services, the data characteristics of SOME / IP services can be periodically classified, the characteristics of each type of data can be clarified, and the classification efficiency of SOME / IP services can be improved.
[0047] Data characteristics are divided into periodic (sensor data) and non-periodic (diagnostic requests). This application embodiment also includes data volume (such as video stream bandwidth requirements).
[0048] Furthermore, S3 includes: Get the traffic category of TSN; Determine TSN priority based on traffic category; Map the TSN priority to the service category to obtain the TSN parameters for the SOME / IP service.
[0049] In the above implementation process, by mapping TSN priority to service category, the detailed classification of SOME / IP services can be mapped to TSN priority, clearly defining the TSN priority of each SOME / IP service.
[0050] Traffic categories mapped to TSNs based on service categories are shown in the table below:
[0051] Furthermore, S4 includes: Configure extended interface information according to TSN parameters; Build a service instance based on the interface information; Build a hybrid bandwidth allocation strategy based on service instances.
[0052] In the above implementation process, by configuring extended interface information and building service instances according to TSN parameters, and by constructing specific hybrid bandwidth allocation strategies, reasonable bandwidth resource allocation for SOME / IP services can be achieved, reducing the waste of bandwidth resources.
[0053] This application embodiment extends the AP AUTOSAR CM module interface and configures the TSN parameters of the SOME / IP service on the ara::com interface, which must include traffic type, real-time type, bandwidth and data characteristics.
[0054] Furthermore, the steps for constructing a hybrid bandwidth allocation strategy based on service instances include: Determine if the service instance is a newly added service instance; If so, determine the hybrid bandwidth allocation strategy to allow services with higher TSN priority to preempt bandwidth resources with lower TSN priority; If not, when the traffic category in the service instance is the first traffic category or the second traffic category, the hybrid bandwidth allocation strategy is to reserve bandwidth resources of the first resource threshold and use the remaining bandwidth resources of the second resource threshold as dynamic contribution resources. If not, when the traffic category in the service instance is the third or fourth traffic category, a pre-defined mixed bandwidth allocation strategy is adopted.
[0055] In the above implementation process, different bandwidth allocations are made according to different service instances, which can improve the utilization of bandwidth resources and enhance the communication capabilities of SOME / IP services.
[0056] In this embodiment of the application, the first traffic category is Class A, the second traffic category is Class B, the third traffic category is Class C, and the fourth traffic category is Class D.
[0057] Design static communication time windows for Class A / B services, whose communication is controlled and monitored by the TSN central network.
[0058] Taking a service with a 10ms cycle as an example:
[0059] When a new service instance is added, the AP AUTOSAR CM module sends a bandwidth request to the TSN central network controller and allows high-priority services to preempt low-priority bandwidth resources. Generally, Class A / B reserves 50% (first resource threshold) of the total bandwidth resources, and the remaining 50% (second resource threshold) is used as a dynamic contribution pool for Class C / D and the newly added service instance.
[0060] For Class C / D services, a pre-defined hybrid bandwidth allocation strategy, namely WFQ (Weighted Fair Queuing), is adopted, and its weights need to be dynamically calculated based on real-time load.
[0061] This application ensures that highly critical services have exclusive access to resources through refined classification, and balances determinism and flexibility through hybrid bandwidth allocation, thereby synergistically guaranteeing the real-time performance of SOME / IP services and the rationality of bandwidth allocation.

[0063] In the above implementation process, more granular classification of SOME / IP services and mapping them with TSN priorities can improve the granularity of SOME / IP service classification, separate bandwidth resources used for critical services, avoid anomalies caused by shared bandwidth, improve bandwidth allocation efficiency, and make adaptive adjustments when new service instances are added to improve bandwidth utilization.

[0070] Furthermore, classification module 2 is also used for: Obtain the data characteristics of SOME / IP services; If the data characteristics are sensor data, then the periodicity category is determined to be periodic; If the data feature is a diagnostic request, determine the periodicity category as non-periodic.

[0072] Furthermore, mapping module 3 is also used for: Get the traffic category of TSN; Determine TSN priority based on traffic category; Map the TSN priority to the service category to obtain the TSN parameters for the SOME / IP service.
[0073] In the above implementation process, by mapping TSN priority to service category, the detailed classification of SOME / IP services can be mapped to TSN priority, clearly defining the TSN priority of each SOME / IP service.
[0074] Furthermore, Module 4 is also used for: Configure extended interface information according to TSN parameters; Build a service instance based on the interface information; Build a hybrid bandwidth allocation strategy based on service instances.
