The ever increasing competition of present day has made the timely and cost effective development of high-quality, precision products, of great importance to various industries. Hence, applications of computer simulation have radically increased in recent years. This paper presents a development of vehicle dynamics simulation and animation environment using Matlab-Virtual Reality Toolbox which can be used for the analysis of vehicle performance. This simulation tool consists of three modules (simulator, preprocessor, and animator) and can provide comprehensive responses and animation of different vehicle maneuvers.

Drivability and powertrain refinement continue to gain importance in the assessment of overall vehicle quality. This notion has transcended its light duty origins and is beginning to gain considerable traction in the medium and heavy duty markets. However, with drivability assessment and refinement also comes the high costs associated with vehicle testing, including items such as test facilities, prototype component evaluation, fuel and human resources. Taking all of this into account, any and all measures must be used to reduce the cost of drivability evaluation and powertrain refinement. This paper describes an analysis based co-simulation methodology, where sophisticated powertrain simulation and objective drivability evaluation tools can be used to predict vehicle drivability. A fast running GT power engine model combined with simplified controls representation in Matlab/Simulink was used to predict engine transients and responses.
