VR(Virtual Reality) simulation becomes a useful method in automobile industry because of its benefit to curtail expenses and reduce the risk of experiments. In this study, VR simulation which makes it possible to consider the effect of driver, is applied to evaluate dynamic characteristics of ASV(Advanced Safety Vehicle). The VR system, which is constructed, generates visual and sound information of the vehicle and the driving environment. The mathematical model of vehicle dynamics and ASV functions are also proposed for simulations. ACC(Adaptive Cruise Control) function and FVCWS(Forward Vehicle Collision Warning System) are selected as ASV function for this study. The real-time simulation algorithm synchronises vehicle dynamics simulation with VR rendering. Some scenarios are also suggested for evaluating ASV function. The ASV VR simulation results are compared with experiments. The simulation results showed that the VR simulation is very useful method for evaluating dynamic characteristics of the ASV on various driving conditions.

The main system function of the FVCWS (Forward Vehicle Collision Warning System) is to warn the driver when the following vehicle encounters the situation when a leading vehicle in the following vehicle's trajectory becomes a potential hazard. Much research on the warning algorithms for the FVCWS has been carried out. However, human factors to design the warning algorithms for the FVCWS must be considered to decide the suitable warning critical distance. In this study, the driver's perception response experiment is carried out on the VR (Virtual Reality) based vehicle simulator. The experimental results against driver's perception response time and the maximum vehicle deceleration corresponding to leading vehicle's sudden braking are reflected to the forward vehicle collision warning algorithm which decides the warning critical distance. It can be useful in the design of the FVCWS with due regard to human factors such as driver's behavior and driving characteristics on various driving conditions.

A driving simulator has been treated as very useful instrument not only to test the components of future cars but a1so to evaluate the telematics service and HMI(Human-Machine Interface). However driving simulators can't be implemented to test and evaluate the telematics service system because these are located in indoor side where the GPS(Global Positioning System) signal of real satellites may not reach. This paper presents a method to implement telematics service to a driving simulator by developing the GPS Simulator which is able to emulate GPS satellite signals consist of NMEA-0183 protocol and RS232C communication standards. It is expected that the driving simulator applied the GPS simulator will be widely used to study HMI and human-factor evaluations because of benefits to plug the commercial telematics system on directly and to realize the HiLES(Human-in-the-Loop Evaluation System).
