Research Topics


Vehicle simulation capability will be enhanced by developing comprehensive, real-time subsystem models that will be integrated into their multi-body vehicle dynamics simulation. This simulation technology will be used in both driver and hardware-in-the-loop performance evaluations of vehicle systems. An equations of motion based approach will be used to build a suite of dynamic subsystems models. To provide the most cost effective and efficient environment. the models will be developed and evaluated as separate models on a personal computer and then later ported offer and integrated into the TACONI multi-boa! architecture. As part of the evaluation process the models mill be integrated into an existing personal computer based real-time simulator to insure that no anomalies occur. Using a specified vehicle. a prototype demonstrating the feasibility of the approach, will be developed. A set of currently existing subsystem models that have been developed for passenger vehicles and heavy trucks will be used as the starting foundation. Based on TACOM's needs, the hardware environment and the fidelity requirements of the models, the base set of models will be enhanced or replaced: and other desired models that are not part of the base set, will be developed. BENEFITS: At the successful completion of this project a suite of ground vehicle dynamic subsystem models will be available for use in computer simulations and engineering analysis. The models mill be capable of uncorking on a wide variety of computer platforms and therefore can be applied in fields such as real-time simulation, hardware prototyping.
