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).

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.

Rollover is defined as a vehicle rotation of 90 degree or more around its longitudinal axis. Understanding the effects of vehicle and tire properties on the rollover propensity is an essential research. In this paper, the sensitivity analysis of vehicle and tire design variables has been investigated by vehicle rollover analysis, which contains multi-body vehicle dynamic models and nonlinear tire models. For the purpose, the several orthogonal arrays based on the DOE (Design of Experiments) analysis has been constructed, and main effects and percent effects of each vehicle and tire design variable has been discussed on diverse rollover characteristics.

Single vehicle accidents sometimes lead to vehicle rollover. Rollover is defined as a vehicle rotation of 90 degree or more around its longitudinal axis. In this paper, the multi-body vehicle dynamic model has been constructed to investigate vehicle rollover propensity. The vehicle dynamic model consisted of body, suspension, steering, power-train, brake, tire, road, and driver subsystems. The whole vehicle parameters, each vehicle's part parameter, part connecting elements such as spring, damper and bush, and tire characteristic factors were measured by an experiment to accomplish accurate rollover analysis. With the developed vehicle dynamic model, rollover characteristic analysis due to tire characteristic factors, such as cornering stiffness and cornering force peak has been carried out.
