| Abstract | This study demonstrates that simulation using MATLAB is an effective approach for evaluating and enhancing the performance of power split hybrid electric vehicles (HEVs). The system combines an internal combustion engine and an electric motor through a planetary gear mechanism, allowing flexible and efficient power distribution under varying driving conditions. A detailed HEV model is developed in MATLAB/Simulink, incorporating key components such as the engine, motor, battery, transmission, and control strategy. The model is analyzed under standard driving cycles to assess fuel consumption, battery state of charge (SOC), torque sharing, and overall efficiency. An energy management strategy dynamically allocates power between the engine and motor to optimize energy usage and reduce emissions, while regenerative braking is employed to recover energy during deceleration. Simulation results indicate that the proposed power split HEV significantly improves fuel economy and reduces emissions compared to conventional vehicles. This work highlights the importance of MATLAB-based simulation as a reliable tool for the design and optimization of sustainable hybrid vehicle systems. |
