After the millennium, tendencies show that the utilization of alternative fuel vehicles gains increasing popularity. Beside several other promising concepts, the development of electric driven vehicles is remarkable. The main purpose of these recent powertrain solutions is to provide higher performance with improved efficiency and to reduce the consumption and the pollution. Furthermore, the development not only affect the vehicle’s drive system but also the intelligence of the cars. The Autonomous Driven Electric Vehicle (ADEV) project is established in the Group of Electrical Engineering to get knowledge about the applied systems in the automotive industry and to develop such a vehicle. The topic of this paper is strongly associated to this project.

The first chapter presents the situation and possibilities of the alternative fuel vehicles in the market and details especially the potential of the Hybrid and All-Electric vehicles. Moreover, the market spread of these cars is discussed and the issues that must be solved in order to compete with traditional internal combustion engines.

In the second chapter, the focus is on the electric motors that can be used as a base of a traction system. The operation and structure of the different types are introduced which highlights on their pros and cons and explore their field of use.

The third chapter focuses on the Brushless DC motor as it is chosen to drive the vehicle of the ADEV project. The mathematical representation of the motor in MATLAB Simulink is described with the necessary model of the inverter. Furthermore, the cascade control of the BLDC motor is also discussed and the results of the different simulations are presented which utilize the prepared models.

The next chapter of the paper shortly describes the essence of the Hardware-in-the-Loop development environment in a meaningful example. After that, the schematic structure of a HIL system is designed which support the development of the ADEV project.

In the final part, the project’s further planes are summarized which promotes the construction of the envisioned vehicle.
