Numerical Investigation of Hybrid Electric Vehicle’s Performance

This paper presents a comparative study about the performance of a classic, hybrid and electric bus by computer simulation using AVL Cruise software. The simulation tasks include main energetic, functional and dynamic parameters, over the usual city bus drive cycle. Based on the simulation results, a comparative analysis was performed for the three models of buses used for urban passenger transport. Hybrid and electric vehicles have been developed with the aim of saving energy, reducing local pollutant emissions and can be considered to offer the best short term to mid-term promise. The impact on the fuel economy generally improves by more than 50 % in urban passenger’s traffic using hybrid buses.
