Parallel hybrid electric vehicle PHEV design and building

Abstract

The project comes as a response to the modern trends in the automotive world, which could be summarized into two main factors , the growing interests in the protection of the environment and the reduction of pollutions, the trend towards reducing dependence on traditional fuels which become a key element in the scientific automotive research , and here comes the idea of hybrid vehicle running on an additional source of energy in addition to the conventional fuelssuch as electricity and hydraulic pressure. A parallel hybrid which includes more than one energy source can provide propulsion power, the heat engine ( internal combustion engine) and the electric motor. The project was implemented on four-wheel drive (2WD) vehicle with diesel engine, electric machines will be incorporated to drive rear axle, here the electric system drives the rear wheels, and the IC engine the front. The vehicle can be traveled by IC engine in front axle in specified operation condition in this mode the electric motor working as generator, and on the other hand can be traveled by electric motor by using rear axle at low speed at city drive cycleand charging the batteries at regenerative braking. This hybrid vehicle contains DC/AC inverter and AC driver to control the current and speed of electric motor, special batteries used for charging, control circuite to control the system in different operation mode. The project shows the design and analysis of the forces affecting on the mechanical system and all electrical circuits calculations.
