Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Unless defined otherwise, all technical terms used in the embodiments of the present disclosure have the same meaning as commonly understood by one of ordinary skill in the art.
With the emergence of new technologies such as Advanced Driving Assistance System (ADAS), hybrid electric vehicle, active safety System, and even automatic Driving, the development of technologies such as infotainment System, and the like, the Network bandwidth and transmission speed of traditional networks such as Controller Area Network (CAN) cannot meet the transmission of huge data volume inside the vehicle. The network capacity demand of the vehicle-mounted network is rapidly increased, and the Ethernet is more suitable for a new technology than the traditional automobile networks such as CAN or FlexRay.
The vehicle-mounted Ethernet gateway is used as a central communication node of the vehicle-mounted Ethernet, realizes communication service between a vehicle and the outside by connecting a remote information control unit, and simultaneously ensures the safety of vehicle information through a firewall and intrusion detection for data accessed from the outside.
Automotive gateways, also known as vehicle connectivity gateways (CVG) or vehicle connectivity gateways (CCG), are vehicle access points (entry points) that allow vehicles to communicate with the outside world and can securely interconnect and transmit data within a plurality of different networks within a vehicle. Through physical isolation and protocol conversion, information interaction is performed between functional domains (powertrain, chassis and safety, body control, infotainment, telematics, ADAS) that share data. Vehicles increasingly rely on Electronic Control Units (ECUs) to enhance the driving experience. As a communication bridge among various ECU networks, a gateway controller realizes data exchange through an external interface (including high-low speed CAN, LIN, ISO-9141, FlexRay and Ethernet protocols) and plays a fundamental role.
However, in the related art, the vehicle-mounted ethernet gateway needs to change software codes when updating the routing information, and a large amount of software tests are needed after the change, which is time-consuming and labor-consuming, and software problems are easy to occur.
In addition, many controllers in the vehicle need to be refreshed in a host factory according to customer requirements or new functions, and due to the long update period of gateway software, the generation beat of the workshop is slowed down.
Therefore, the present disclosure provides a vehicle-mounted ethernet gateway, where the function configuration module is connected to an upper computer through an ethernet interface, and is capable of receiving a configuration file issued by the upper computer, and the function configuration module performs update iteration on routing information of the application software layer and/or the basic software layer, without changing a bottom code, and is capable of quickly and safely implementing update iteration of gateway software, thereby being beneficial to improving the production rhythm of a host factory, and improving the response efficiency of a vehicle product to customer requirements and new functions.
It is to be understood that the term "vehicle" or other similar term as used herein is intended to encompass motor vehicles in general, such as passenger cars (including sport utility vehicles, buses, trucks, etc.), various commercial vehicles, and the like, as well as hybrid vehicles, electric vehicles, and the like. A hybrid vehicle is a vehicle having two or more power sources, such as gasoline-powered and electric vehicles.
Hereinafter, an in-vehicle ethernet gateway according to exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In the context of the present disclosure, the term "gateway" is used to denote a network device that transports PDUs at the OSI level of hierarchy. It is a network device that allows control module networks using different communication protocols and different communication rates to communicate with each other, including but not limited to a bridge, switch, router, or application layer routing gateway device. "vehicle ethernet gateway" refers to the relevant gateway device for vehicle ethernet.
Fig. 1 is a schematic structural diagram of a vehicle-mounted ethernet gateway according to an embodiment of the present disclosure.
On one hand, referring to fig. 1, the present embodiment provides a vehicle ethernet gateway 100, where the vehicle ethernet gateway 100 includes: at least one Ethernet Interface 1(Ethernet Interface), Application Layer 2(Application Layer), interaction Layer 3, Basic Software Layer 4 (BSW), and function configuration module 5; the function configuration module 5 is connected with the upper computer 200 through at least one Ethernet interface 1; the function configuration module 5 is configured to be capable of receiving a configuration file issued by the upper computer 200 and updating the routing information of the application software layer 2 and/or the basic software layer 4.
In the vehicle-mounted ethernet gateway 100 of this embodiment, the function configuration module 5 is connected to the upper computer 200 through the ethernet interface 1, and can receive the configuration file issued by the upper computer 200, and the function configuration module 5 performs update iteration on the routing information of the application software layer 2 and/or the basic software layer 4, without changing the bottom code, so that update iteration of the gateway software can be quickly and safely implemented, which is beneficial to improving the production rhythm of a host factory, and improving the response efficiency of a vehicle product to customer requirements and new functions.
In some possible implementation manners, the vehicle-mounted ethernet gateway 100 is based on an automobile Open System Architecture (AUTOSAR), the application software layer 2 includes software required by an automobile host factory and related to functions, the interaction layer 3 is a bridge for interaction between different modules of the application layer and between the application software layer 2 and the base software layer 4, and the base software layer 4 includes a Microcontroller Unit (MCU) and a peripheral device driver thereof, a hardware abstraction layer, and a service layer for providing an interface service for an upper application.
Illustratively, the interaction layer 3 is a Runtime Environment (RET), which is a specific implementation of the AUTOSAR Virtual Function Bus (VFB) of a specific ECU, and supports communication among software components of the AUTOSAR, among base software, and between the software components and the base software. The RTE encapsulates the communication and services of the base software layer 4, and provides standardized base software and communication interfaces for the software components of the application layer, so that the application layer can call the services of the base software through the API functions.
The application software layer 2 is located above the RTE in the structure and is composed of application components, and one special application component in the application components is a sensor/actuator component. An RTE supports both software components for which source code is available (source code software components) and software components for which only object code is available (object code software components).
As another example, the base software Layer 4 includes a microprocessor Abstraction Layer (MCAL), an ECU Abstraction Layer, a service Layer, and a complex driver. The MCAL is driving software of the MCU, and carries out register operation encapsulation on the operation of each peripheral module. The ECU abstraction layer is driven by some more on-board hardware resources than MCAL, such as external watchdog, off-chip EEPROM or FLASH, etc. The service layer is further encapsulation and abstraction, and generally includes an OS, power state management, vehicle-wide network communication, diagnostic services, storage services, and the like. The complex driver comprises drivers of hardware devices which are not in the automotive standard specification, such as a motor driver, a plurality of more complex sensor drivers and the like.
As used herein, the terms "plurality", "at least one" mean one or more, and the terms "plurality", "at least two" mean two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In some embodiments, the functional configuration module 5 is a graphical router management tool developed according to the automotive open systems framework standard.
AUTOSAR is a consortium of global automobile manufacturers, component suppliers, and other electronic, semiconductor, and software systems companies, each maintaining development partnerships. Since 2003, partner companies have worked with themselves to develop an open, standardized software architecture for the automotive industry. The AUTOSAR architecture is beneficial to exchange and update of vehicle electronic system software and provides a foundation for efficient management of increasingly complex vehicle electronic and software systems. In addition, AUTOSAR improves cost efficiency while ensuring product and service quality.
Illustratively, the function configuration module 5 is (Security Device Manager, SDM).
SDM is a completely new graphical router management tool offered by Cisco corporation. The tool utilizes a WEB Interface, Java technology and an interactive configuration guide to enable a user to easily complete state monitoring, safety audit and function configuration of an IOS (Internet Operating System) router without knowing a Command Line Interface (CLI).
The configuration tasks such as Quality of Service (QoS), Intrusion Prevention System (IPS), dynamic host configuration protocol DHCP Server, and dynamic routing protocol may also be easily and quickly completed by using SDM. The use of SDM can simplify the workload and the probability of errors for the network administrator. When the SDM is used for management, the encrypted HTTP connection and the SSH v2 protocol are used between the user and the router, and the security and the reliability are realized.
As shown in connection with FIG. 1, in some embodiments, the host computer 200 includes a web services orchestrator 6; the web services orchestrator 6 is configured to receive the communication matrix description file and output the configuration file to the functional configuration module 5 using the DoIP diagnostic flash protocol.
Therefore, when the gateway software is updated and iterated, the vehicle-mounted ethernet gateway 100 of this embodiment does not need to change the bottom code of the software, and only needs to import the communication matrix description file to the upper computer 200, and issue the configuration file to the SDM module through the ethernet interface 1 of the gateway by using the DoIP diagnostic flash protocol, and the latest version of routing data is configured to implement the new version of routing.
Illustratively, the web services orchestrator 6 is a tool for automated configuration, coordination, and management of computer systems and software.
Illustratively, the DoIP is a communication Protocol based on ethernet to transmit data of the UDS Protocol, i.e. a Diagnostic communication over Internet Protocol. It is also a protocol per se, and is specified in the ISO13400 standard. Because the DoIP CAN transmit a large amount of data, has a fast response speed, and CAN perform remote diagnosis through the ethernet, the DoIP gradually becomes a bus mode for replacing the traditional CAN and the like, and becomes an inevitable trend of vehicle-mounted network diagnosis.
In some embodiments, the communication matrix description file is tagged using Extensible Markup Language (XML).
In electronic computers, tags refer to information symbols that can be understood by computers, and through XML tags, computers can process information including various kinds, such as articles, and the like. It can be used to mark data, define data types, and is a source language that allows a user to define his or her own markup language. Is well suited for world wide web transport and provides a unified approach to describing and exchanging structured data that is application or vendor independent. Is a cross-platform, content-dependent technology in the Internet environment and is also an effective tool today for processing distributed structural information. As early as 1998, the XML1.0 specification was published by W3C, which was used to simplify the transmission of Internet documents.
Using the XML tag communication matrix, it can be more easily combined with information generated under Windows, Mac OS, Linux, and other platforms, and then it is easy to load XML data into a program and analyze it, and output the result in XML format.
In some possible implementations, a Communication Matrix (Communication Matrix) is usually defined by the entire vehicle factory, and each node in the vehicle network needs to follow the Communication Matrix to complete the interaction and sharing of information.
For passenger cars, after satisfying the UDS (universal Diagnostic Services) and the exhaust emission protocol, a significant part of the ID segment remains. These ID fields are assigned by the host factory, and after assignment, form an XML formatted table. The table may be imported as a communication matrix into the upper computer 200.
In some embodiments, at least one Ethernet interface 1 is a 100BASE-TX interface. Two pairs of 5-type unshielded twisted pairs or 1-type shielded twisted pairs are used, one pair is used for sending data, the other pair is used for receiving data, the maximum network segment length is 100m, and the wiring conforms to the EIA568 standard; the 4B/5B coding method is adopted, so that the data can be transmitted by serial data stream of 125 MHz; it supports full duplex, using MLT-3 (multi-level transmission-3) waveform method to reduce the signal frequency to 125/3-41.6 MHz. 100Base-TX makes the most widely used physical layer specification in 100 Base-T.
Where the number 100 represents the frequency of the mesh wire design in units of mhz (megahertz). I.e. 100 MHz. The larger the value of MHz, the faster the speed supported by the network cable. If you try to use this type of network cable in higher frequencies (and speeds) it will not work or become extremely unreliable. 100MHz is transmitted at 100Mbit per second, which theoretically means 12 Mbps. However, in practice, more than 4Mbps may not yet be available. BASE is an abbreviation for BASE band, which refers to baseband. Meaning that each signal completely controls the cable at a single frequency without using frequency division multiplexing or other frequency conversion techniques. T represents the physical medium carrying the signal as a Twisted Pair cable (divided into UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair)), where each Pair of signal carrying Twisted pairs is intertwined with each other (between FEXT and NEXT) to reduce electromagnetic interference and crosstalk. There are a number of different standards at the same transfer rate, with one letter or number following the T/F/C to distinguish between them (e.g., TX). It shows the structure of the mesh wire and indicates the number of pairs of wires involved. Some high speed standards use coaxial cable, then assigned the designation CX.

The vehicle-mounted ethernet gateway 100 of the present embodiment can solve the problem of mutual communication between a Telematics BOX (Telematics BOX) and a large screen of a central control host, an automatic driving system, ethernet DOIP diagnosis, and the like, and establish an ethernet communication intermediate bridge.
