Abstract
The goal of this work of thesis is to analyze the control strategies implemented in an electric-hybrid vehicle and transfer them into a virtual environment. In this perspective, a simulation tool, including the complete plant model of the vehicle and the electronic control unit (ECU) of the Powertrain, has been developed and integrated with torque management strategies for the control and the coordination between electric and internal combustion propulsion. The whole tool is MATLAB/Simulink based. The starting point has been an existing plant model of a conventional vehicle composed of thermal engine, automatic transmission and vehicle dynamics. The model has been analyzed and upgraded to integrate the electric motors, organized in a P1P4 configuration (Electric AWD).
At this point the torque split strategies actually used in real hybrid vehicles have been evaluated, including the concept of cost function, and integrated in the simulation tool
