Detailed Description
The following is further detailed by way of specific embodiments:
the first embodiment is as follows:
the embodiment discloses a vehicle cloud cooperative control system based on SOA.
As shown in fig. 1, the car cloud cooperative control system based on the SOA includes:
a cloud server for issuing a service invocation request (via APP);
the vehicle-mounted network terminal is used for receiving and generating a corresponding service calling instruction according to the service calling request of the cloud server;
the in-vehicle domain controller is used for receiving and executing corresponding service calling according to the service calling instruction of the vehicle-mounted network terminal;
the executor is used for executing corresponding service functions according to the service calling condition of the in-vehicle domain controller; in this embodiment, the actuator and the in-vehicle domain controller communicate with each other in a hard wire, a CAN, a LIN, or other communication manner.
The in-vehicle domain controller is further used for abstracting hardware resources and application business processes in the vehicle, defining corresponding atomic services and atomic service interfaces and application abstract services and application abstract service interfaces, and establishing corresponding service architectures.
According to the invention, hardware resources and application business processes in the vehicle are abstracted, and then corresponding atomic services and atomic service interfaces and application abstract services and application abstract service interfaces are defined to establish corresponding service architectures, so that service abstraction of a domain controller and a lower-hanging actuator thereof in the vehicle, service calling of functions in the vehicle and service unification of vehicle cloud coordination are realized, and further a foundation can be provided for mutual calling of vehicle cloud services and flexible arrangement of vehicle-side services, so that expandability and flexibility of vehicle cloud coordination control functions can be improved, and a foundation can be effectively provided for SOA-based vehicle cloud coordination control. Meanwhile, the cloud server indirectly calls the in-vehicle service of the in-vehicle domain controller through the vehicle-mounted network terminal, and the service abstraction of the in-vehicle domain controller and the lower-hanging actuator thereof, the service calling of the in-vehicle function and the service unification of the vehicle cloud cooperation enable the efficiency and the flexibility of the vehicle cloud communication to be improved based on the SOA framework, so that the isomorphism and the cooperation efficiency of the vehicle cloud cooperation communication can be improved.
In a specific implementation process, the cloud server and the vehicle-mounted network terminal are communicated through a Message Queue Telemetry Transport (MQTT) protocol.
In this embodiment, a message queue telemetry transmission proxy server (MQTT Broker) is deployed at a cloud server, and a corresponding message queue telemetry transmission proxy (MQTT Client) is deployed at a vehicle-mounted network terminal, so that the cloud server can issue a corresponding service invocation request (based on a 4G/5G network) through the message queue telemetry transmission proxy server, and the vehicle-mounted network terminal can subscribe the corresponding service invocation request through the message queue telemetry transmission proxy server. Meanwhile, a corresponding message queue telemetry transmission agent (MQTT Client) is deployed at the cloud server and used for subscribing service execution responses issued by the vehicle-mounted network terminal.
In the specific implementation process, the vehicle-mounted network terminal and the in-vehicle domain controller communicate with each other through a vehicle-mounted Ethernet communication (SOME/IP) protocol. In this embodiment, corresponding vehicle-mounted ethernet communication protocol stacks are deployed in the vehicle-mounted network terminal and the in-vehicle domain controller, respectively.
After the initialization is completed, the vehicle-mounted network terminal initiatively initiates service discovery to acquire corresponding services, and after receiving service messages provided by corresponding in-vehicle domain controllers, establishes a service binding relationship (namely a service calling mapping relationship) based on key information (such as IP addresses, port numbers and the like of service providing terminals); after receiving a service calling request issued by an MQTT server, the vehicle-mounted network terminal initiates service calling to a corresponding in-vehicle domain controller and receives service execution response based on the service binding relationship and the RPC (remote procedure call) mechanism of the SOME/IP.
In the specific implementation process, the data formats and data structures in the message queue telemetry transmission protocol and the vehicle-mounted Ethernet communication protocol load are kept consistent (for example, JSON formats are adopted, and parameter names and parameter values are consistent); and a conversion middleware (Middle Ware) for realizing the interconversion between the message queue telemetry transmission instruction and the vehicle-mounted Ethernet communication instruction is deployed on the vehicle-mounted network terminal.
According to the invention, the cloud server and the vehicle-mounted network terminal are communicated through MQTT, and the vehicle-mounted network terminal and the vehicle-mounted domain controller are communicated through SOME/IP, so that the cloud server can realize indirect calling of the vehicle-mounted service of the vehicle-mounted domain controller through the vehicle-mounted network terminal, and the service abstraction of the vehicle-mounted domain controller and a lower hanging actuator thereof, the service calling of the vehicle-mounted function and the service unification of vehicle cloud cooperation are realized, thereby improving the efficiency and flexibility of vehicle cloud communication based on an SOA framework. Meanwhile, the data formats and data structures in the MQTT protocol and the SOME/IP protocol load are kept consistent, so that the vehicle-mounted network terminal can directly intercept and load the load related to the service call request in the received MQTT protocol into the SOME/IP protocol load without analyzing and translating parameters in the load, the load consistency of the MQTT protocol and the SOME/IP protocol can be ensured, and the vehicle cloud cooperative communication efficiency can be further improved.
In a specific implementation process, after the executor completes execution of the corresponding service function, the executor feeds back a corresponding service execution response to the in-vehicle domain controller, and then feeds back the corresponding service execution response to the cloud server sequentially through the in-vehicle domain controller and the vehicle-mounted network terminal. In this embodiment, after receiving the service response of the corresponding domain controller, the vehicle-mounted network terminal may directly intercept and load the load related to the service execution response in the received SOME/IP protocol to the MQTT protocol load and publish the load to the MQTT server (subscribed by the cloud server), without performing load parameter analysis and translation during the process.
After the execution of the corresponding service function is completed, the executor can feed back a corresponding service execution response to the in-vehicle domain controller, and then the service execution response is fed back to the cloud server through the in-vehicle domain controller and the vehicle-mounted network terminal in sequence, so that the cloud server can timely and accurately acquire the execution condition of service calling, and the isomorphism and the cooperative efficiency of vehicle-cloud cooperative communication can be improved.
