ELECTRONIC DATA PROCESSING SYSTEM HAVING A VIRTUAL BUS SERVER APPLICATION

摘要

An electronic data processing system comprises a first application program that is capable of operating in a first mode and a second mode. The first mode comprises software emulation of a vehicle data bus and one or more network elements. The second mode comprises communications access to the vehicle bus and the one or more network elements. The electronic data processing system is capable of executing an operating system. A virtual bus server application comprises a shared memory and a message router. The operating system facilitates communication between at least two dynamic link libraries in shared memory. The message router is capable of routing data messages between the first application and a first hardware module as a network element in the second mode. A first dynamic link library interface provides an interface between the first application program and the virtual bus server application. The first dynamic link library is capable of communicating with the shared memory of the virtual bus server application. A second dynamic link library interface provides an interface between the virtual bus server application and the first hardware module. The second dynamic link library is capable of communicating with the shared memory of the virtual bus server application.
