A 24 degree-of-freedom full vehicle-driving simulator is proposed in this paper. The simulator provides a full immersive graphical virtual scenery and force/motion feedback cues for the driver. The simulator has been developed to provide an open architecture in a local network environment. Using Matlab/Simulink one can interface with the vehicle model through this environment, designing and testing vehicle sub models while evaluating the ride performance of the vehicle. The development and implementation of a rollover detection and warning system is discussed, to illustrate the application of the driving simulator.

Voltage and current surges are a major concern when it comes to ensuring the functional integrity of electrical and electronic components and modules in an automobile system. This paper presents a computer simulation study for analyzing the effect of high voltage spikes and current load dump on a new Integrated Driver/Receiver (IDR) IC, currently being developed for a J1850 Data Communication Bus in an automobile. It describes the modeling and simulation of the protection structure proposed for the device. The simulation study yields a prediction of current and voltage capability of the protection circuit based on thermal breakdown and transient responses of the circuit. Two levels of modeling, namely, the behavioral level model and the component level model, are used to generate the simulation results. Experimental data will be acquired and used to validate the simulation model when the actual device becomes available.
