The project “Bizzarrini P538 Eco Targa” has been developed by the INFOCOM department of " Sapienza" University of Rome. The project consisted in the design and construction of a replica of a historic Italian car, updated with LPG fuel and with modern parallel hybrid-type plug-in technologies, with a start and stop system, and a Lithiumpolymer battery storage system. The research aimed at undertaking practical experimentation on parallel hybrid vehicles, with a special focus on the problems related to the construction and optimization of hybrid propulsion systems. The prototype constructed is made of a space-frame chassis, which is composed of tubular sections of various thicknesses and Fe360 material, with double wishbone with push rod as suspension system. The internal combustion engine is mounted at the rear axle. It is petrol engine 2.2 JTS with direct injection with 185 Hp and 225 Nm. The electric motor, together with its electronic control, is at the front axle, and the motor is a brushless type with 22 kW of power rating and 45 kW of peak power. The electric motor is powered to 222 Vdc from a storage system made of lithium polymer batteries produced by Kokam, with 6.68 kWh of stored energy. A PC/104 embedded pc type has been used as main controller of the hybrid system. The control unit not only supervises and controls the hybrid traction, but enables the display of all operational information of the prototype on a screen positioned within the prototype itself. The simulation model was obtained by coupling the simulation software vehicle dynamics GT-Drive with the Matlab / Simulink environment, to optimize control strategy of the prototype.
