Abstract

Claims (27)

1. A machine including an electronic control unit (ECU) to which a portable operating system interface (POSIX) operating system (OS) is ported and implementing dynamic-service-oriented communication between vehicle applications on an AUTomotive Open System ARchitecture (AUTOSAR) adaptive platform (AP), the machine comprising:

a skeleton which is an application for providing a service on the platform;

a proxy which is an application using the service on the platform; and

a service communication management (CM) which is an application for brokering service-oriented communication between vehicle applications on the platform,

wherein the service CM comprises:

a service registry configured to store information on the service provided by the skeleton and information on the service used by the proxy;

a service discovery configured to transmit a notification of starting to provide the service or a search request message (a service discovery message) for using the service through Ethernet multicast when a service registered in the service registry is to be provided to a vehicle application of another ECU or use the vehicle application of the other ECU;

a Scalable service-Oriented MiddlewarE over Internet protocol (SOME/IP) bridge in charge of data communication in accordance with a service provided or used by the other ECU; and

an inter-process communication (IPC) port used in communication between the skeleton and the proxy,

wherein the IPC port is a port for communication with the skeleton and the proxy existing in the same machine, and

wherein when a received message is a service discovery message, the IPC port transfers the message to the service registry, and when the received message is a service message, the IPC port transfers the message to the SOME/IP bridge.

2. The machine of claim 1 , wherein the service CM further comprises:

a service discovery multicast port configured to transmit the service discovery message generated by the service discovery to the other ECU through Ethernet multicast, receive a service discovery message transmitted by the other ECU through Ethernet multicast, and transfer the service discovery message to the service discovery; and

a service endpoint port used in data communication between the SOME/IP bridge and the other ECU.

3. The machine of claim 2 , wherein the service endpoint port follows a transmission control protocol (TCP) or a user datagram protocol (UDP).

4. The machine of claim 1 , wherein the service CM is only one in the machine.

5. The machine of claim 1 , wherein the skeleton and the proxy are not directly connected to each other, and

the skeleton or the proxy communicate with the CM through IPC.

6. An input message processing method of a service communication management (CM) when a message is input to an inter-process communication (IPC) port of the service CM which brokers service-oriented communication between vehicle applications, the input message processing method comprising:

transferring the message to a service registry in which information on a service provided or used in a corresponding machine is stored;

when the message is one of a start-of-service-provision notification message and search request message for service use, and service information related to the message has not been registered in the service registry, registering the service information related to the message in the service registry;

when the message is a stop-of-service-provision notification message, and service information related to the message has been registered in the service registry, removing a tuple of the service information related to the message from the service registry; and

when the service information is of a Scalable service-Oriented MiddlewarE over Internet protocol (SOME/IP) type, generating a message notifying of a start of service provision according to a SOME/IP and transmitting the message to another electronic control unit (ECU).

7. An input message processing method of a service communication management (CM) when a message following a Scalable service-Oriented MiddlewarE over Internet protocol (SOME/IP) protocol is input to a service discovery multicast port of the service CM which brokers service-oriented communication between vehicle applications, the input message processing method comprising:

transferring the message to a service registry in which information on a service provided or used in a corresponding machine is stored;

when the message is one of a start-of-service-provision notification message and search request message for service use, and service information related to the message has not been registered in the service registry, registering the service information related to the message in the service registry; and

when the message is a stop-of-service-provision notification message, and service information related to the message has been registered in the service registry, removing a tuple of the service information related to the message from the service registry.
