Appropriate structure is the first key issue that a designer of an efficient hybrid vehicle should pay attention to. This paper presents three different structures for the concept of series–parallel structure in hybrid electric vehicles (HEVs) and compares them with each other for the application of Toyota Prius 2004 as a well-known case study. The first structure consisting of one electric motor,...
The dual mechanical port machine (DMPM) is a new generation electrical machine with two rotors and one stator. The DMPM can be used as an EVT system regarding to independently rotation capability of its two rotors. When this machine is applied in a hybrid electric vehicle, it can perform all the functions of Toyota Hybrid System by more compact and integrated structure. In this article, a new control...
In this paper, optimal design of dual mechanical ports machine based series-parallel hybrid electric vehicle has been presented. The target of optimization is vehicle main performance factors such as maximum vehicle speed, maximum gradability factor and minimum 0–60 mph acceleration time. In optimization process, ICE always biased on fuel optimum operation line. After obtaining machine dimensions...
Pollution and limited fossil fuels are the critical issues that lead HEVs to emerge. Nowadays new designs and topologies of HEVs are suggesting and developing. In this paper we have dynamically modeled and simulated a new structure of series-parallel HEV based on a special machine named Transmotor and applied it to Toyota Prius 2004. In This structure, generator and planetary gear in common series-parallel...
In this paper, a dynamic model for Toyota Prius 2004 hybrid electric vehicle (HEV) is presented. The model is based on MATLAB Simulink HEV model which is modified in such a way that dynamic response of model can be verified by experimental results given in DOE reports for Toyota Prius 2004. The newly developed model can help the designers to enhance the performances of subsystems.
