Abstract

The present invention relates to a method and apparatus for setting up a vehicle network based on AUTomotive Open System ARchitecture (AUTOSAR). The apparatus for setting up a vehicle network based on AUTOSAR includes a screen unit for externally receiving structure setup input values. A structure setup unit is configured such that when a user selects an Electronic Control Unit (ECU) and a communication cluster on the screen unit, the structure setup unit displays a communication channel between the ECU and the communication cluster, and sets up a network structure based on the communication channel. A data setup unit sets up data that is transmitted through the communication channel using a wizard which is software for executing software or hardware operations using an interrogatory method.

Claims

1. An apparatus for setting up a vehicle network based on AUTomotive Open System ARchitecture (AUTOSAR), comprising:

a screen unit for receiving structure setup input values;

a structure setup unit for, when a user selects an Electronic Control Unit (ECU) and a communication cluster on the screen unit, displaying a communication channel between the ECU and the communication cluster, and setting up a network structure based on the communication channel; and

a data setup unit for setting up data that is transmitted through the communication channel using a wizard which is software for executing software or hardware operations using an interrogatory method.

2. The apparatus of claim 1, wherein the structure setup unit comprises:

an ECU instance generation unit for generating ECU instances, each operating in conjunction with a communication controller block and a communication connector block for each ECU, on the screen unit;

a cluster instance generation unit for generating communication clusters corresponding to types of communication buses on the screen unit;

a connection line generation unit for generating connection lines for connecting the ECU instances to the communication clusters; and

a property setup unit for setting up properties of the generated instances using a specific properties viewer.

3. The apparatus of claim 2, wherein the cluster instance generation unit generates a FlexRay cluster when the communication bus is a FlexRay bus, and generates a Controller Area Network (CAN) cluster when the communication bus is a CAN bus.

4. The apparatus of claim 3, wherein the cluster instance generation unit generates a relevant physical channel whenever each communication cluster is generated.

5. The apparatus of claim 2, wherein the connection line generation unit generates a communication controller block and a communication connector block between each ECU instance and each communication cluster and generates reference blocks corresponding to the communication controller block.

6. The apparatus of claim 1, wherein the structure setup unit sets up the network structure using a graphical user interface.

7. The apparatus of claim 1, wherein the wizard comprises a system signal wizard, an Interaction layer Protocol data unit (IPdu) wizard, and a frame wizard.

8. The apparatus of claim 7, wherein the data setup unit comprises:

a signal generation unit for generating system signals and Interaction (I) signals using the system signal wizard;

an IPdu generation unit for generating IPdus using the IPdu wizard;

an ECU selection unit for selecting a source ECU instance and a destination ECU instance from among the ECU instances using the frame wizard; and

an IPdu selection unit for selecting an IPdu corresponding to a frame for a type of a communication bus between the source ECU instance and the destination ECU instance.

9. The apparatus of claim 8, wherein the IPdu further comprises a Pdu-to-frame mapping instance.

10. The apparatus of claim 8, wherein the IPdu selection unit generates a frame triggering instance, which includes information about frames to be transmitted through a physical channel, using a communication connector block generated by the structure setup unit.

11. A method of setting up a vehicle network based on AUTomotive Open System ARchitecture (AUTOSAR), comprising:

receiving structure setup input values;

setting up data that is transmitted through the communication channel using a wizard which is software for executing software or hardware operations using an interrogatory method.

12. The method of claim 11, wherein the setting up the network structure comprises:

generating ECU instances, each operating in conjunction with a communication controller block and a communication connector block for each ECU;

generating communication clusters corresponding to types of communication buses; and

generating connection lines for connecting the ECU instances to the communication clusters.

13. The method of claim 12, wherein the generating the communication clusters comprises:

generating a FlexRay cluster when the communication bus is a FlexRay bus; and

generating a Controller Area Network (CAN) cluster when the communication bus is a CAN bus.

14. The method of claim 13, wherein the generating the communication clusters is configured to generate a relevant physical channel whenever each communication cluster is generated.
