Comparative Results of a Developed Vehicle Dynamic Model for a Sedan Electric Vehicle

The interest in electric vehicles (EVs) is significantly increased due to the awareness of internal combustion engine (ICE) effects towards the environmental and sustainability issue. In developing EVs projects, computer modelling of the vehicle dynamic and simulation can be utilized to estimate the battery power requirement and predict the optimum cruising strategies which in return will shorten the design development process and reduce the cost of prototyping. This paper presents the effectiveness of the vehicle dynamic simulation model of a converted internal combustion engine vehicle PROTON SAGA sedan into a fully EV called EVerGREEN. The simulation model is set to analyse the effect of the vehicle dynamic parameters such as vehicle resistance and the motor characteristics in predicting the optimum driving profile. The development of the electric vehicle EVerGREEN is shortly presented together with the vehicle dynamic model. The driving performance is measured based on a real road test at F1 Sepang International Circuit and the results are validated by comparing between the simulation model and the actual drive test. Simulation and experimental results are shown to verify the effectiveness of the proposed model which shows a good agreement between them. Further works in enhancing the model effectiveness could be implemented by incorporating the battery characteristics and hence would provide better energy management for the vehicle.
