A lane departure warning system developed under a virtual environment

In recent years, many advanced driver assistant systems (ADAS) are developed to address great concerns on vehicle safety. However, the testing and verification of ADAS can be very time consuming, costly and even dangerous. This paper presents a vision-based lane departure warning system (LDW) that is developed under a virtual environment. The lane departure warning system consists of an image processing module and a pre-warning module. The LDW system in this paper is not novel or creative, it´s just a object to show how a LDW system can be developed ender a virtual environment. The LDW system is largely developed under a real-time virtual environment that includes two dSpace1401-based MicroAutoboxes (MABX), a desktop PC, a dSpace1006-based real-time simulator, and the required communication buses. Some preliminary simulation has been conducted to verify the proposed camera model and virtual driving environmental model, and the results show that the proposed verification environment is valid and effective.
