Abstract: Given the imperative to reduce reliance on finite fossil fuel resources and mitigate associated environmental pollution, adopting cleaner energy alternatives becomes imperative. This underscores the significance of advancing electric and hybrid vehicle technologies. In recent times, academia and industries have focused on smart electric cars. They vary in many capabilities, which are the essential constituents of intelligent speed control. This work focuses on the dynamic modelling and longitudinal speed control of a level-one smart electric car employing GT-suite and MATLAB. In the validation of the GT-suite model, experimental open-loop tests are conducted. Next, a proportional-integral controller is designed on both software platforms in an integrated fashion, followed by carefully tuning its parameters. The developed controller is then tested for performance under various conditions: slope of the road, wind effects and different forms of reference speed inputs.

Keywords: GT-suite; electric vehicle; Simulink; speed control; dynamic modelling.
