Detailed Description

In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the following description explains the english abbreviations of the related technical terms:

SOA: service-Oriented Architecture, service-oriented architecture

CDC: cockpit Domain Controller Intelligent cabin controller (cabin controller)

ADAS: advanced Driver Assistance System advanced auxiliary driving system (auxiliary driving system described below)

And (3) ECU: electronic Control Unit, electronic control unit

TBox: telematics-BOX, vehicle-mounted communication terminal

GW: gateway, gateway

VLAN: virtual Local Area Network virtual local area network

ARP: address Resolution Protocol Address resolution protocol

As an example, with the intellectualization of vehicles, more and more ECUs (Electronic Control Unit, electronic control units) need to be networked, such as ADAS (Advanced Driver Assistance System, advanced assisted driving system), central gateway, intelligent cabin, etc. And, along with the domain fusion, different product forms appear in each whole vehicle part manufacturer, such as a cabin and an ADAS are fused, a gateway and a Tbox (Telematics-BOX) are fused, and the like, and in the process of fusion, the network communication module may be located on different ECUs, including being placed on the Tbox, or the module may be placed on the GW, and the situation that the network communication module exists on multiple ECUs at the same time may also occur.

In the above process, the networking deployment scheme of the vehicle basically comprises that vehicle manufacturers determine the whole network topology structure according to a defined EE architecture, then allocate corresponding VLANs according to service requirements, and each ECU manufacturer carries out corresponding network configuration (such as IP addresses, VLANs and the like) according to topology interfaces. For APP internet policy inside the ECU, for example, what APN (Access Point Name ) network is used for internet surfing, the corresponding networking policy is basically fixed in advance or is obtained by the ECU from the cloud of a certain docking vehicle manufacturer, the policy obtaining mode is requested through HTTPS mode, the obtained policy also only comprises APN1 (private network) and APN2 (public network), and no WiFi network is included. After the policy is obtained, the APP carries out networking access after binding the allocated VLAN IP address. Therefore, in this case, for the whole vehicle networking of the vehicle, based on the immobilization of the hardware, the networking strategy of the vehicle is too single to adapt to different application scenes, and when the hardware is abnormal, the networking is easy to fail, so that corresponding vehicle service cannot be provided for the user.

In the invention, for the gateway and a plurality of different electronic control units configured in the vehicle, a network management server component can be configured in the gateway, and a network management client component is configured in each electronic control unit, when the application in the corresponding electronic control unit needs to be networked, the electronic control unit can firstly determine a target resource identifier corresponding to the application, then send the target resource identifier to the network management server through the network management client component, the network management server component locates the target network equipment corresponding to the target resource identifier, and takes the target network equipment as a networking entrance, and a network channel between the electronic control unit and the target network equipment is established, so that the electronic control unit realizes networking through the network channel, thereby overcoming the networking limitation caused by mutual independence between hardware, realizing the uniformity of network resources, improving the expansibility and controllability of the whole vehicle networking, simultaneously carrying out point-to-point network resource allocation based on the resource identifier, enriching the networking strategy and reducing the development cost.

Referring to fig. 1, a flowchart of steps of a networking method of a vehicle provided in an embodiment of the present invention is shown, where the vehicle is deployed with a gateway and several electronic control units; each electronic control unit is deployed with a network management client component, and the gateway is deployed with a network management server component, which specifically comprises the following steps:

Step 101, determining a target resource identifier corresponding to an application networking request of an application program by a first electronic control unit in response to the application networking request;

in a vehicle, a gateway and several electronic control units may be deployed, different electronic control units may be used to provide different vehicle functions, the electronic control units may include a cabin controller, an assisted driving system, an on-board communication terminal, etc., wherein the cabin controller may be used to monitor and control the operation of various systems of the vehicle, such as an engine, a transmission, a brake, a suspension, an entertainment system, etc.; the driving assistance system may be used to provide driver assistance and safety functions to enhance the convenience, comfort and safety of driving; the in-vehicle communication terminal may provide vehicle remote communication, in-vehicle interconnection functions, and the like.

Alternatively, for each electronic control unit, a corresponding application (i.e. APP) may be run, which provides corresponding services to the user via networking. Different application programs can be networked through different networks (private network, public network, wifi network and the like), and based on different networking strategies, each electronic control unit can be networked through a corresponding networking mode, normal operation of each electronic control unit is guaranteed, and vehicle experience of a user is improved.

In the invention, a network management client component (NMC) and a network resource client component (NRC) can be configured in each electronic control unit, a network management service component (NMS) and a network resource service component (NMS) are configured in a gateway, and by matching among the components, the network deployment of the whole vehicle can be realized, the expansibility and controllability of the whole vehicle network can be improved, so that each electronic control unit can realize networking without paying attention to the position of a network communication module when networking demands exist, the network is realized through the registration of a network node of the component, for a developer, each ECU provider does not need to know the network topology structure of the whole vehicle, then a corresponding network port is independently created based on the network topology, the routing configuration and the network access strategy are realized, and the provider only needs to integrate a component library provided by a cost scheme, thereby greatly reducing the development cost of the product and shortening the development period.

The NRC can be responsible for managing actual physical resources of the electronic control unit, including wifi resources, mobile communication network resources and the like; the NRS can be responsible for managing the whole vehicle network resources and managing and controlling networking strategies, such as allocation according to the network signal strength of the network resources; NMC may be responsible for allocation of network interfaces, including selecting appropriate network resources, etc., depending on the type of application; the NMS can be responsible for policy management of whole vehicle network interface allocation, creates an executed VLAN network according to the current network resources and the request of the ECU, and the like, and can realize unified allocation of the whole vehicle networking of the vehicle by mutual coordination among all components, thereby improving the expansibility and controllability of the whole vehicle networking.

In SOME possible implementations, referring to fig. 2, a schematic diagram of a communication architecture provided in an embodiment of the present invention is shown, in a vehicle, by using an Ethernet (ETH) as a backbone network of communication, a fixed mac address and an IP address are allocated to each ECU, where the ECU includes a CDC, an ADAS, a Tbox, and the like, and a basic SOA communication is established between each ECU and a gateway, where a SOA/IP may be selected by a communication protocol of the SOA, and corresponding network management components and network resource components may be deployed in each ECU and gateway based on a communication protocol stack of the SOA. The NRS, NMS and NPC (network policy configuration) are deployed in Gateway, where the NPC may be a configuration setting for managing network access control, for example, may perform access control on a private network; NRC and NMC are deployed in CDC, NMC is deployed in ADAS, NRC is deployed in Tbox, etc. Specifically, each ECU may operate a corresponding APP (e.g., CDC operation APP1, APP2, ADAS operation APP1, tbox operation APP1, etc.), and different APPs implement networking through different networking policies, e.g., APP1 networking through a private network, APP2 networking through a public network, etc. In addition, the network communication module may include a wifi module, a mobile network module, and the like, and the mobile network module may include a module such as 4G, 5G, and the like, and in the vehicle, the 5G module is exemplified, and then the wifi module may be deployed in the CDC, and the wifi module and the 5G module may be deployed in the Tbox, where the 5G module in the Tbox may provide a networking manner of APN1 (private network) and APN2 (public network).

In a specific implementation, for a whole vehicle networking strategy, aiming at an ECU (electronic control unit) provided with network communication modules, the ECU can acquire a resource identifier corresponding to the network communication modules through a network resource client component, convert the resource identifier into a data object corresponding to an SOA (service oriented architecture) communication protocol, send the data object to a gateway, register the resource identifier through a network resource server component according to the data object so as to monitor each network communication module based on the resource identifier, thereby completing registration of network resources, and carrying out corresponding network resource allocation based on the registered network resources under the condition that networking requirements exist later. Different network resources correspond to different resource identifiers, for example, wifi resources and 5G resources may correspond to different resource identifiers respectively.

In one example, a wifi module is deployed in the CDC, then the CDC may acquire a resource identifier (1) corresponding to the wifi module through the NRC, then the resource identifier (1) may be abstracted into a data object a of the SOA, and the data object a is sent to the NRS of the gateway, and correspondingly, a wifi module and a 5G module are deployed in the Tbox, then the Tbox may acquire a resource identifier (2) and a resource identifier (3) corresponding to the wifi module and the 5G module through the NRC, and then abstract into a data object b and a data object c of the SOA, and send the data object b and the data object c to the NRS of the gateway. For NRS of gateway, the operation is started after the vehicle-mounted operation system is started, data objects sent by NRC are monitored, and then wifi modules in CDC, wifi modules in Tbox and 5G modules are registered based on the data objects, so that NRS can manage whole vehicle network resources and control networking strategies based on registered network resources conveniently.

Optionally, for management and control of networking strategies, the NRS may allocate network resources according to network signals corresponding to each network communication module, for example, there are a plurality of WiFi modules in the vehicle, and two ECUs, i.e., TBox and CDC, have WiFi modules, so that the NRS may sort according to the strength of the hot spot signals scanned by each network device, when the CDC needs to surf the internet through WiFi at this time, the WiFi module with a higher hot spot signal in the TBox may be selected to perform network connection, so that the gateway performs unified management and allocation on the whole vehicle network resources through the NRS, and expansibility and controllability of whole vehicle networking are improved.

In addition, for components such as NMC, NRC, NMS and NRS, the components can be provided in the form of a so library and a binary, and can be adapted to various platforms, including Linux, QNX, android and other platforms, which the present invention is not limited to.

In the networking process of the vehicle, when one of the electronic control units (such as the first electronic control unit) detects an application networking request of an application program, the first electronic control unit can acquire the application program identifier of the application program, generate a networking policy acquisition request for the application program identifier, then send the networking policy acquisition request to a network management server side component through a network management client side component, and receive a networking policy list returned by the network management server side component, wherein the networking policy list comprises a mapping relation between the application identifier and a resource identifier, and then the network management client side extracts a target resource identifier corresponding to the application program identifier from the networking policy list so as to allocate network resources based on the target resource identifier. Optionally, for the application identifier, for the Android system, the application identifier may be a package name of the application program; for the Linux system, the process name can be obtained, so that the resource identifier bound with the application identifier can be determined by obtaining the corresponding application identifier, and further, what network resource is built by the application program is determined, and networking of the application program is ensured.

In the NMS, a corresponding networking policy list may be managed, where the networking policy list includes a mapping relationship of what network resources are used by an application program to perform networking, that is, a mapping relationship between an application identifier and a resource identifier, for example, APP1-wifi, APP2-5G, etc., so that the NMS performs allocation of network resources based on the mapping relationship.

In some possible embodiments, the electronic control unit is further configured with a network service and an interface library, where the network service may acquire the networking policy list by calling the interface library, specifically, the electronic control unit may generate a corresponding networking policy acquisition request through the network service, and then the network service calls the interface library to send the networking policy acquisition request to the network management client component, and the network management client component sends the networking policy acquisition request to the network management server component to acquire the corresponding networking policy list based on the SOA communication protocol. The interface library may be an externally provided interface library responsible for communication with the NMC.

Referring to fig. 3, a schematic diagram of a software architecture provided in an embodiment of the present invention is shown, taking an Android system as an example in CDC deployment of network resource client and network management client, when APP on the CDC needs to be networked, a network service of the CDC may generate a corresponding networking policy acquisition request, and call a libnmagent.

Alternatively, for the interface function of the interface library libnmagent.so, the following table may be used:

step 102, the target resource identification is sent to the network management server-side component through the network management client-side component of the first electronic control unit;

after the network management client component of the first electronic control unit determines the target resource identifier of the network resource to be constructed by the application program, the target resource identifier can be sent to the network management server component of the gateway, so that the network management server component selects the corresponding network device as a networking inlet of the first electronic control unit based on the target resource identifier, and networking of the first electronic control unit is realized.

And step 103, positioning target network equipment corresponding to the target resource identifier through the network management server-side component, taking the target network equipment as a networking entrance, and establishing a network channel between the first electronic control unit and the target network equipment.

In the embodiment of the invention, after the network management server side component receives the target resource identifier, the corresponding target network equipment can be positioned from the vehicle, then the target network equipment is used as a networking entrance of the first electronic control unit and is responsible for sending a corresponding request to the cloud and receiving data returned by the cloud, and the like, so that a network channel between the first electronic control unit and the target network equipment is established, the networking limitation caused by mutual independence between hardware is overcome under the condition of networking the whole vehicle, unified allocation of network resources is realized, the expansibility and controllability of networking of the whole vehicle are improved, meanwhile, the point-to-point network resource allocation is carried out based on the resource identifier, the networking strategy is enriched, and the development cost is reduced.

In some possible embodiments, the network device may be an electronic control unit deployed with network communication modules, and in the process of positioning and selecting the network device, the network resource server component may be used to position the first network communication modules corresponding to the target resource identifier, obtain network signals corresponding to the first network communication modules, and then use the electronic control unit to which the second network communication module with the strongest network signal belongs as the target network device corresponding to the target resource identifier.

Optionally, for the target network device, the network management server component may further create a corresponding network forwarding rule for the target network device, where the network forwarding rule may be a rule set for specifying how network traffic is forwarded and forwarded by the target network device in the networking process, where the network forwarding rule may include a routing rule of a target address, an access control rule of a firewall, a policy routing rule, a forwarding rule of a VLAN, and so on, in the vehicle entire vehicle networking, a data packet of the electronic control unit may be forwarded to a specific VLAN based on the forwarding rule of the VLAN, so that traffic isolation and communication between different virtual local area networks, that is, traffic isolation and communication between "a first electronic control unit-gateway-network device", "a network device-cloud" and so on are implemented.

For example, for wifi modules, the method can include a first wifi module deployed in a CDC and a second wifi module deployed in a Tbox, then NMS can obtain hot signals corresponding to each wifi module respectively, then order according to hot signal intensity, and then take ECU where the wifi module with the highest hot signal is located as corresponding network equipment, which is responsible for data interaction with a cloud, so that network resource allocation is performed based on resource identification, independence among various ECUs is broken, networking scenes of vehicles can be free of paying attention to what ECU the network communication module is located, unified management of network resources is achieved, unified management of network system resources is conducted for vehicles, expansibility of vehicle networking is improved, flow control and access control are facilitated, and for vehicle manufacturers, network resource allocation modes based on components are used, so that the various ECUs do not need to know network topology structures of the whole vehicle, development cost can be greatly reduced, and development period of products is shortened.

In addition, after the network channel between the first electronic control unit and the target network device is established, the application program is enabled to realize networking, corresponding data can be obtained from the cloud, specifically, interface information corresponding to the target resource identifier and sent by the network management server side component can be received through the network management client side component of the first electronic control unit, and a data request is sent to the target network device through the first electronic control unit according to the interface information so as to realize data interaction with the cloud. The method comprises the steps that as the same network communication module exists in a vehicle, target network equipment can be detected according to interface information, and if a first network communication module corresponding to the interface information exists in a first electronic control unit, a data request is sent to the Ethernet through the first network communication module of the first electronic control unit; if the first electronic control unit does not have the first network communication module corresponding to the interface information, the first electronic control unit sends a data request to the gateway according to the interface information, then the gateway sends the data request to the target network equipment, the target network equipment is a second electronic control unit different from the first electronic control unit, and then the second electronic control unit sends the data request to the Ethernet through the second network communication module corresponding to the interface information.

The interface information may include an MAC address, an IP address, etc., and the ECU to be networked may send a corresponding request to the corresponding network device through the MAC address, the IP address, etc., so as to implement data interaction with the cloud through the network device. For example, assuming that APP1 in the CDC needs networking, the target resource identifier is a wifi resource identifier, and wifi modules are deployed in the CDC and the Tbox respectively, after the NMS obtains the hotspot signals corresponding to each wifi module according to the wifi resource identifier, the NMS can select the wifi module with the highest hotspot signal as the network device from the hotspot signals, and if the network device is the CDC, the CDC can perform data interaction with the cloud based on the wifi module of the CDC; if the network equipment is a Tbox, the CDC can transmit corresponding data requests and the like to the Tbox, the Tbox realizes data interaction with the cloud through a wifi module of the Tbox and returns a data interaction result to the CDC, so that the network limitation caused by mutual independence between hardware is overcome under the networking scene of the whole vehicle, unified allocation of network resources is realized, the expansibility and controllability of the networking of the whole vehicle are improved, meanwhile, point-to-point network resource allocation is carried out based on resource identification, networking strategies are enriched, and development cost is reduced.
