[0033] In related technologies, the electrical and electronic architecture (EEA) is an electronic and electrical solution for the entire vehicle that integrates the vehicle's electronic and electrical systems, ECU (Electronic Control Unit), various sensors, wiring harnesses, connector designs, and electronic and electrical distribution systems.

[0034] Based on the automotive EE architecture, the in-vehicle Ethernet is introduced to facilitate better data communication between the various ECUs in the car. At present, the common Ethernet communication protocol in the car is the SOME / IP (Scalable service-oriented middleware over IP) protocol. However, the MCU (Microcontroller Unit) in some in-vehicle ECUs is not equipped with Ethernet hardware and protocol stacks, and cannot communicate with other MCUs on the in-vehicle Ethernet.

[0035] In response to the problems existing in the above-mentioned related technologies, the present application proposes a communication method and device, a computer storage medium and a terminal, which can at least enable an MCU that is not configured with Ethernet hardware and protocol stack to communicate with other MCUs on the microprocessor MPU vehicle Ethernet.

[0036] Figure 1 A schematic diagram of a first application scenario of a communication method provided according to an embodiment of the present application is shown.

[0037] Reference Figure 1 As shown, the first application scenario includes an MCU and an MPU (Microprocessor Unit), the MCU and the MPU perform inter-core communication, and the MCU and the MPU are located in a vehicle-mounted control device. The MCU includes an application 101 and a SOME / IP interface 102, and the SOME / IP interface 102 is a virtual SOME / IP interface. The MPU includes an agent module 103 and a SOA (Service Oriented Architecture) module 104.

[0038] When in use, the MPU obtains the first information from the MCU in the form of inter-core communication, and the first information is generated by the MCU's application 101 calling the SOME / IP interface 102; the proxy module 103 in the MPU parses the first information and generates a SOME / IP service message; the SOA module 104 of the MPU calls the corresponding service based on the SOME / IP service message, that is, the MPU communicates with other nodes on the vehicle Ethernet based on the SOME / IP service message. In this application scenario, the MPU communicates with other nodes on the vehicle Ethernet based on the SOME / IP service message, and the MCU communicates indirectly with the vehicle Ethernet through the MPU, without the need to equip the MCU with Ethernet hardware and protocol stack, thereby enabling the MCU that is not equipped with Ethernet hardware and protocol stack to communicate with other nodes on the vehicle Ethernet, wherein the node on the vehicle Ethernet can be an on-board control device, other MCU or ECU in the vehicle.

[0039] Figure 2A schematic diagram of a second application scenario of the communication method provided according to an embodiment of the present application is shown.

[0040] Reference Figure 2 As shown, the second application scenario includes a first MCU201, a first MPU202, a second MPU203 and a second MCU204, the first MCU201 and the first MPU202 perform inter-core communication, the second MCU204 and the second MPU203 perform inter-core communication, and the first MPU202 and the second MPU203 communicate via the vehicle Ethernet. Among them, the first MCU201 and the second MCU204 both include an application and a SOME / IP interface, and the SOME / IP interface is a virtual SOME / IP interface. The first MPU202 and the second MPU203 both include a proxy module. The application, SOME / IP interface and proxy module in this application scenario are consistent with those in the above application scenario, and will not be repeated in this embodiment.

[0041] When in use, the first MPU202 obtains first information from the first MCU201 in an inter-core communication manner, where the first information is generated by the application of the first MCU201 calling the SOME / IP interface; the proxy module in the first MPU202 converts and parses the first information to generate a first SOME / IP service message; the first MPU202 sends the first SOME / IP service message to the second MPU203 through the vehicle Ethernet, and the second MPU203 parses and converts the first SOME / IP service message and sends it to the second MCU204 through the inter-core communication manner, and the second MCU204 receives the message, so that the first MCU201 and the second MCU204 communicate with each other; or

[0042] The first MPU202 obtains the second SOME / IP service message through the vehicle Ethernet, and the second SOME / IP service message is generated by the proxy module of the second MPU203; the proxy module of the first MPU202 converts and parses the second SOME / IP service message to generate a second message; the first MPU202 sends the second message to the first MCU201 in the form of inter-core communication, and the first MCU201 receives the second message, so that the first MCU201 and the second MCU204 can communicate with each other. That is, in this application scenario, the first MPU202 and the second MPU203 communicate with the vehicle Ethernet, and the first MCU201 and the second MCU204 are both equipped with Ethernet hardware and protocol stacks. The first MCU201 communicates with the vehicle Ethernet through the first MPU202, and the second MCU204 communicates with the vehicle Ethernet through the second MPU203, thereby enabling the first MCU201 and the second MCU204 to communicate with each other.

[0043] Figure 3A flow chart of a communication method provided according to an embodiment of the present application is shown. The execution subject of the communication method may be a computing device with a computing and processing function, such as the MPU in the vehicle control device in the first application scenario, or the first MPU 202 and the second MPU 203 in the second application scenario. The communication method includes steps S301 to S303. The communication method in the example embodiment is described in detail below in conjunction with the accompanying drawings.

[0044] Reference Figure 3 As shown, step S301: the first microprocessor obtains first information from the first micro control unit in an inter-core communication manner.

[0045] In an example embodiment, the first information is generated by an application of the first MCU calling the SOME / IP interface, and the application may be an application in the first application scenario or the second application scenario described above. The SOME / IP interface of the first MCU is a virtual SOME / IP interface, and the first message is a virtual SOME / IP service message. Inter-Process Communication (IPC) is a multi-core system in which the cores often need to communicate due to application requirements. For example, when multiple processors need to share peripherals, memory, and interrupts between processors, inter-processor communication (IPC) implements this function. Inter-core communication is mainly used in two aspects: sending interrupts to other cores and transmitting small amounts of data between cores.

[0046] The first MPU obtains the first information from the SOME / IP interface of the first MCU in an inter-core communication manner. During this process, communication is established between the first MPU and the first MCU without going through the in-vehicle Ethernet.

[0047] Step S302: parsing and generating a first SOME / IP service message based on the first information.

[0048] In an exemplary embodiment, the first SOME / IP service message is a service message generated by the first MPU according to the SOME / IP protocol of Ethernet. The first MPU parses the first information and generates the first SOME / IP service message.

[0049] Specifically, in one embodiment, the first MPU includes a proxy module, and the first MPU parses the first message based on the proxy module and generates a first SOME / IP service message.

[0050] Understandable, refer to Figure 4As shown, in a specific embodiment, the first MPU includes a proxy module, the proxy module includes a data conversion unit and a Some / IP proxy unit, and the first MPU converts the first message based on the data conversion unit of the proxy module; the first MPU parses the converted first message based on the Some / IP proxy unit of the proxy module, and generates a first SOME / IP service message.

[0051] It should be noted that, in this embodiment, the proxy module is an Agent program. The application program of the first MCU calls the SOME / IP interface to generate a first message, which is a virtual SOME / IP service message. The Agent program maps the first message to the action Agent function, and the Agent function converts and parses the data format of the first message to generate a real first SOME / IP service message that complies with the Ethernet protocol stack.

[0052] Step S303: Based on the first SOME / IP service message, the first microprocessor communicates with other nodes on the vehicle Ethernet.

[0053] In an example embodiment, the first MPU sends a first SOME / IP service message to the vehicle Ethernet so that the first microprocessor communicates with other nodes on the vehicle Ethernet, and then the first microcontroller unit communicates with other nodes on the vehicle Ethernet through the first microprocessor.

[0054] It can be understood that, in combination with the above-mentioned example embodiments, the first MPU includes an agent module, which is an Agent program. The Agent program receives a first message generated by the first MCU, converts and parses the first message to generate a first SOME / IP service message that complies with the protocol stack, and then sends the first SOME / IP service message to other nodes on the vehicle Ethernet. The other nodes on the vehicle Ethernet receive the first SOME / IP service message, thereby enabling the first microprocessor to communicate with other nodes on the vehicle Ethernet.

[0055] In addition, it should be noted that the nodes on the vehicle Ethernet in this example embodiment can be an onboard computer or other MCUs and ECUs in the vehicle. In one embodiment, if the first MCU in the vehicle needs to communicate with another MCU, the other MCU may be equipped with Ethernet hardware and a protocol stack, or may not be equipped with Ethernet hardware and a protocol stack. If the other MCU is equipped with Ethernet hardware and a protocol stack, the other MCU can directly parse the first SOME / IP service message to establish communication. If the other MCU is not equipped with Ethernet hardware and a protocol stack, the other MCU can convert and parse the first SOME / IP service message through the MPU that establishes inter-core communication with it, so as to realize communication between the first MCU and the second MCU.

[0056] according to Figure 3 The technical solution in the example embodiment of the first MPU obtains the first information from the first MCU in the form of inter-core communication, and the first information is generated by the application of the first MCU calling the SOME / IP interface; the first MPU parses the first information and generates a SOME / IP service message; the first MPU sends the first SOME / IP service message to other nodes on the vehicle Ethernet to communicate with other nodes on the vehicle Ethernet. In the embodiment of the present application, the first microprocessor obtains the first information from the first microcontroller unit in the form of inter-core communication, and the first microprocessor communicates with the vehicle Ethernet through the SOME / IP service message, so that the first microcontroller unit can indirectly communicate with the vehicle Ethernet, and then communicate with other nodes on the vehicle Ethernet, without configuring Ethernet hardware and protocol stack on the first microcontroller unit, which is portable and does not rely on hardware.

[0057] Furthermore, in this exemplary embodiment, the Agent program is used to replace the complex protocol stack and the corresponding Ethernet hardware, which can greatly simplify the configuration of the first MCU, has portability, and is not restricted by hardware conditions.

[0058] Figure 5 A flow chart of a communication method provided according to another embodiment of the present application is shown. The execution subject of the communication method may be a computing device with a computing and processing function, such as the first MPU and the second MPU in the vehicle control device in the second application scenario. The communication method includes steps S501 to S503. The communication method in the example embodiment is described in detail below in conjunction with the accompanying drawings.

[0059] Reference Figure 5 As shown, step S501: the first microprocessor obtains a second SOME / IP service message through the vehicle-mounted Ethernet.

[0060] In an exemplary embodiment, in combination with the above exemplary embodiment, the vehicle control device further includes a second MCU and a second MPU, the second MCU and the second MPU communicate with each other, and the second MPU communicates with the vehicle Ethernet. The second SOME / IP service message is a service message generated by the second MPU according to the SOME / IP protocol of the Ethernet.

[0061] It can be understood that the second MPU generates a second SOME / IP service message and sends the second SOME / IP service message to the in-vehicle Ethernet, and the first MPU communicating with the in-vehicle Ethernet receives the second SOME / IP service message.

[0062] Step S502: Generate a second message based on the second SOME / IP service message.

[0063] In an exemplary embodiment, the second message is a message obtained by parsing and converting the second SOME / IP service message by the first MPU. The second message is a virtual SOME / IP message service and can be received by the SOME / IP interface of the first MCU.

[0064] In combination with the above exemplary embodiments, refer to Figure 4 As shown, the first MPU includes a proxy module, and the proxy module includes a data conversion unit and a SOME / IP proxy unit. The SOME / IP proxy unit of the proxy module of the first MPU parses the second SOME / IP service message; the data conversion unit of the proxy module of the first MPU converts the parsed second SOME / IP service message to generate a second message.

[0065] It can be understood that the agent module is an Agent program, which maps the second SOME / IP service message to the action Agent function. The Agent function parses the second SOME / IP service message and generates a second message after converting the data format. The second message is a virtual SOME / IP message service, which can be received by the SOME / IP interface of the first MCU through inter-core communication.

[0066] Step S503: the first microprocessor sends the second message to the first micro control unit in an inter-core communication manner, so that the first micro control unit communicates with the second micro control unit.

[0067] In an example embodiment, the first MPU performs inter-core communication with the first MCU, and the first MPU sends the second message to the first MCU through the inter-core communication. In a specific embodiment, the first MPU sends the second message to the SOME / IP interface of the first MCU in the form of inter-core communication.

[0068] In combination with the above example embodiments, the Agent function parses the second SOME / IP service message, converts the data format and generates a second message, where the second message is a virtual SOME / IP message service. The virtual SOME / IP message service is sent to the SOME / IP interface of the first MCU through inter-core communication. The SOME / IP interface of the first MCU receives the second message to indirectly realize communication between the first MCU and the second MCU.

[0069] according to Figure 5 According to the technical solution in the example embodiment, the first MPU obtains the second SOME / IP service message through the in-vehicle Ethernet, and the second SOME / IP service message is generated by the agent module of the second MPU; the agent module of the first MPU converts and parses the second SOME / IP service message to generate a second message; the first MPU sends the second message to the first MCU in the form of inter-core communication, and the first MCU receives the second message through the SOME / IP interface of the first MCU and feeds it back to the application in the first MCU, so as to indirectly realize communication between the first MCU and the second MCU.

[0070] In the present application, by adding a first MPU on the first MCU side through inter-core communication, the proxy module of the first MPU has an Agent program, and the Agent program can convert the virtual SOME / IP message information from the first MCU into a service message that complies with the SOME / IP protocol and send it to the vehicle Ethernet; it can also convert the service message of the SOME / IP protocol from other MCUs into a virtual SOME / IP protocol service message and feed it back to the first MCU, so that the first MCU and the second MCU can communicate indirectly. It avoids the integration of complex protocol stacks and corresponding hardware on the first MCU side or the second MCU side, and reduces the dependence on hardware.
