[0002] In the past, vehicle electrical architecture was considered as an integrated whole vehicle. Based on the hardware and software support capabilities of the electrical architecture, the adaptability of the project, and the selection of key electrical components, a suitable vehicle electrical architecture was designed to realize the network communication of vehicle electrical components and the electrical functions of the whole vehicle.

[0003] However, with the emergence of a smart chassis, the vehicle body has become separated into upper and lower body. The lower body can be considered as the customer and can be provided to different vehicle manufacturers to realize the combination of the upper and lower body into a whole vehicle. Therefore, in the vehicle Ethernet communication, the communication between the upper and lower body will naturally be interrupted and interacted.

[0004] Current electrical architectures only consider integrated network communication across the entire vehicle, failing to separate the upper and lower body sections, and further hindering the creation of different vehicle models based on the different upper body sections mounted on the lower body. Therefore, a significant challenge lies in how to break down the vehicle's Ethernet communication into Ethernet segments for the upper and lower body sections, and how to achieve Ethernet network communication isolation between the upper and lower body sections while simultaneously facilitating Ethernet communication interaction between them.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0062] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0063] The vehicle involved in this embodiment of the invention can separate the upper body and the lower body, and different upper bodies can be matched for the same lower body. Furthermore, the lower body involved in this embodiment of the invention specifically refers to the automobile chassis, such as an integrated chassis, electric drive system, thermal management system, 3000mm wheelbase, and four-wheel drive system capable of achieving L4 driving level.

[0064] Please refer to Figure 1 and Figure 2 This invention provides a vehicle architecture with separate Ethernet communication between the upper and lower body, comprising:

[0065] The system includes several upper vehicle body nodes 10, several lower vehicle body nodes 20, and a gateway 30. The upper vehicle body nodes 10 and the lower vehicle body nodes 20 communicate with the gateway 30 via Ethernet. The first chip module 301 and the second chip module 302 have multiple interfaces corresponding to the upper and lower vehicle body nodes respectively, enabling end-to-end Ethernet communication.

[0066] In a specific example, if the lower body has four parts: transmission system, running system, steering system and braking system, and each of the four parts has corresponding units, such as the transmission system having a clutch unit, gearbox unit, differential unit, etc., then the number of nodes in the lower body corresponds to the sum of the number of units in each part, and the lower body nodes and each part unit have a one-to-one relationship. The second chip module has multiple interfaces to connect multiple lower body nodes, realizing a one-to-one relationship between nodes and interfaces.

[0067] The gateway 30 includes: a first chip module 301, a second chip module 302, a data separation layer 303, and an application layer 304.

[0068] The data separation layer 303 includes a first region 3031 and a second region 3032.

[0069] The first chip module 301 is used to receive first data transmitted by the plurality of upper vehicle body nodes 10 and transmit the first data to the first region 3031; the second chip module 302 is used to receive second data transmitted by the plurality of lower vehicle body nodes 20 and transmit the second data to the second region 3032; the first data and the second data are isolated in the data separation layer 303 through the first region 3031 and the second region 3032; wherein the first data and the second data use different data protocols.

[0070] Specifically, the first region 3031 includes: a first Ethernet driver module 30311 and a first Ethernet MAC module 30312; the first Ethernet driver module 30311 is used to receive first data transmitted by the first chip module 301, and unpack the first data and reassemble it for transmission to the first Ethernet MAC module 30312; the first Ethernet MAC module 30312 is used to receive and forward data transmitted by the first Ethernet driver module 30311.

[0071] The second region 3032 includes: a second Ethernet driver module 30321 and a second Ethernet MAC module 30322; the second Ethernet driver module 30321 is used to receive second data transmitted by the second chip module 302, and unpack the second data and reassemble it for transmission to the second Ethernet MAC module 30322; the second Ethernet MAC module 30322 is used to receive and forward data transmitted by the second Ethernet driver module 30322.

[0072] In this invention, the first data of the upper vehicle body and the second data of the lower vehicle body enter the first chip module and the second chip module through several upper vehicle body nodes and several lower vehicle body nodes, respectively, and further enter the first region and the second region of the data separation layer, thereby realizing the isolation of the upper vehicle body data and the lower vehicle body data.

[0073] The application layer 304 is connected to the data separation layer, and the application layer 304 is configured to:

[0074] This is used to receive first data transmitted from the first area 3031 and second data transmitted from the second area 3032, and to convert the first data and the second data according to the protocol and transmit them to the second area 3032 and the first area 3031 respectively; the first data after protocol conversion is transmitted to the plurality of lower vehicle body nodes 20 via the second area 3032 and the second chip module 302, and the second data after protocol conversion is transmitted to the plurality of upper vehicle body nodes 10 via the first area 3031 and the first chip module 301.

[0075] In this embodiment of the invention, the protocol conversion refers to the fact that the protocol data formats of the information contained in the first data transmitted through several upper vehicle body nodes and the second data transmitted through several lower vehicle body nodes are different. Therefore, the protocol conversion is used to map the information contained in the first data to the second data transmission and reception information sequence, so that the format or protocol of the information contained in the first data is the same as the format of the information contained in the second data; or the protocol conversion is used to map the information contained in the second data to the first data transmission and reception information sequence, so that the format or protocol of the information contained in the second data is the same as the format of the information contained in the first data.

[0076] Specifically, the application layer 304 includes: a protocol conversion module 3041 and a data interaction module 3042;

[0077] The protocol conversion module 3041 is used to convert the second data transmitted through the plurality of lower vehicle body nodes 20 into a protocol, so that the protocol-converted second data matches the first data transmitted through the plurality of upper vehicle body nodes 10; or to convert the first data transmitted through the plurality of upper vehicle body nodes 10 into a protocol, so that the protocol-converted first data matches the second data transmitted through the plurality of lower vehicle body nodes 20.

[0078] The data interaction module 3042 is used to filter the first data transmitted through the plurality of upper vehicle body nodes, or the second data transmitted through the plurality of lower vehicle body nodes, or the first data transmitted through the plurality of upper vehicle body nodes after protocol conversion, or the second data transmitted through the plurality of lower vehicle body nodes after protocol conversion, and then interact with the filtered data.

[0079] The vehicle architecture with Ethernet communication separated for the upper and lower body also includes: Protocol Analysis Layer 305;

[0080] The protocol analysis layer 305 connects the data separation layer 303 and the application layer 304. The protocol analysis layer 305 is configured to analyze and acquire the protocol in the first data transmitted through the plurality of upper vehicle body nodes and the second data transmitted through the plurality of lower vehicle body nodes.

[0081] The protocol analysis layer 305 includes a lower protocol analysis layer 3051 and a higher protocol analysis layer 3052.

[0082] The underlying protocol analysis layer 3051 is used to analyze and obtain the underlying protocol in the first data transmitted through the plurality of upper vehicle body nodes and the second data transmitted through the plurality of lower vehicle body nodes.

[0083] The higher-level protocol analysis layer 3052 is used to analyze and obtain the higher-level protocols in the first data transmitted through the plurality of upper vehicle body nodes and the second data transmitted through the plurality of lower vehicle body nodes.

[0084] The "bottom layer" represents the first to fourth layers of the OSI model, and the "bottom layer protocol" represents the protocols transmitted in the first to fourth layers of the OSI model.

[0085] The higher layers represent layers five through seven in the OSI model, and the higher layer protocols represent the protocols transmitted in layers five through seven of the OSI model.

[0086] In one example, data transmitted through several upper vehicle body nodes and data transmitted through several lower vehicle body nodes are analyzed by a protocol analysis layer to obtain the protocols of the data transmitted through the upper and lower vehicle body nodes. This data, along with the corresponding protocol information, is then transmitted to the application layer for protocol conversion and interaction.

[0087] Specifically, the protocol conversion module includes the UPVS software toolkit. The UPVS software toolkit implements protocol conversion, transforming the protocol of data transmitted through several upper vehicle body nodes or several lower vehicle body nodes into a protocol that matches the protocol of the data transmitted through those nodes. For example, if the data transmitted through several lower vehicle body nodes uses the DDS communication protocol, while the data transmitted through several upper vehicle body nodes uses the SOME / IP protocol, the UPVS software toolkit will convert the protocol of the data transmitted through the upper vehicle body nodes to the SOME / IP protocol or the protocol of the data transmitted through the lower vehicle body nodes to the DDS protocol, ultimately ensuring that the protocols used by the data transmitted through the upper and lower vehicle body nodes are consistent.

[0088] After the data undergoes protocol conversion, it enters the data interaction module, where it is filtered. Specifically, for example, if the second data 1 transmitted through several lower vehicle body nodes includes gear position, instantaneous power consumption, and remaining battery information after protocol conversion, while the first data 2 transmitted through several upper vehicle body nodes includes gear position and instantaneous power consumption, the data interaction module will filter the second data 1, that is, filter the data representing the remaining battery information, and then transmit the filtered second data 1 and first data 2 to the several upper vehicle body nodes and several lower vehicle body nodes respectively.

[0089] The vehicle architecture for separate Ethernet communication between the upper and lower vehicle bodies provided by this invention includes data from the upper and lower vehicle bodies entering the first and second chip modules respectively through several upper and lower vehicle body nodes, and further entering the first and second regions of a data separation layer. Within the data separation layer, the upper and lower vehicle body data are separated, and the separated data is transmitted to the application layer. The application layer performs protocol conversion on the first and second data respectively and transmits them to the second and first regions respectively. The protocol-converted first data is transmitted via the second region... The second chip module transmits data to the plurality of lower vehicle body nodes, and the second data after protocol conversion is transmitted to the plurality of upper vehicle body nodes via the first area and the first chip module. This achieves the purpose of separating the upper and lower parts of the vehicle's Ethernet communication, while ensuring effective Ethernet interaction between the upper and lower parts of the vehicle. With the lower vehicle body intelligent chassis unchanged, different upper parts can be quickly derived. Based on the derived different upper parts, the upper part communication is isolated and the interaction is adapted through the gateway, realizing a new type of Ethernet communication that separates the upper and lower parts of the vehicle. This minimizes the amount of Ethernet data modification, saves Ethernet network communication design time, and enables rapid matching of the upper parts of the vehicle.

[0090] Please refer to Figure 3This invention also provides a vehicle communication method, which communicates through the vehicle architecture described above, which uses Ethernet communication between the upper and lower vehicle bodies, and includes:

[0091] S1: Obtain first data and second data; the first data represents the data transmitted through the plurality of upper vehicle body nodes, and the second data represents the data transmitted through the plurality of lower vehicle body nodes.

[0092] S2: The first data and the second data are respectively sent to the first region and the second region via the first chip module and the second chip module for data isolation.

[0093] S3: The first data transmitted in the first region and the second data transmitted in the second region are input to the application layer. The application layer performs protocol conversion on the first data and the second data respectively and transmits them to the second region and the first region respectively. The protocol-converted first data is transmitted to the plurality of lower vehicle body nodes via the second region and the second chip module, and the protocol-converted second data is transmitted to the plurality of upper vehicle body nodes via the first region and the first chip module.

[0095] Processor 11; and

[0096] Memory 12 is used to store the executable instructions of the processor;

[0097] The processor 11 is configured to execute the methods described above by executing the executable instructions.
