VFB Simulator Based On AUTOSAR Standard

Led by the automotive industry, automotive electronic develops vigorously and the scale and complexity of automotive software increase rapidly. To regulate the development of automotive electronic systems, AUTOSAR standard is introduced and soon becomes a new trend in automotive industry.The software components developed based on AUTOSAR standard have standard AUTOSAR interfaces, such they can integrate with other components with standard AUTOSAR interfaces, and their running environment can be ignored at design stage. However, the test and validation of components are still not simple. It should be carried out with hardware at the end of the developing process, which is a waste of resource and time. In order to find the design errors of components at an early stage of development on PC, this paper developed a VFB simulator based on the concept of "Virtual Functional Bus" in AUTOSAR standard.In a modularized way, this paper describes the three main modules of VFB simulator:simulation process module, monitor process module and report generation module. Firstly, in the simulation process module, this paper emulated the actual AUTOSAR development flow, virtualized it and proposed the development process of simulation process module VFB simulator, enabling software component models run on PC. Secondly, in the monitor process module, this paper designed and implemented the monitor process, facilitating users to observe simulating results and control simulating schedule. Then, in the report generation module, the method that records model information and simulation results to generate simulating reports was introduced. Finally, this paper designed a car light control system and used the VFB simulator to validate it.
