Power Split

Planetary power-split hybrid vehicle is a very common structure of hybrid electric vehicle (HEV), which achieves speed and torque double decoupled between engine and wheels. Engine always working on optimal curve is an important reason for low fuel-efficient. Engine speed is controlled by PID, and the optimal loading rate of engine is solved from engine characteristic curves; finally realization of engine working on optimal curve. Offline simulation is used for this algorithm, and comparing with many experimental results demonstrates engine works on operating point; fuel consumption is close to the official fuel consumption of Prius.

The article describes a method to analyze the powertrain operation of electrically driven vehicles in cases of insufficient information (i.e., unknown control algorithms, no torque measurements during vehicle tests). The method implies mathematical modeling with involvement of so-called unknown input observers. A variant of such an observer is proposed. Using that observer, studies of a hybrid vehicle and a pure electric vehicle are performed. The models with torque observers simulated tests of said vehicles conducted on a chassis dynamometer and on roads. For the hybrid vehicle, operating regimes of main powertrain components were identified. For the electric vehicle, the identification revealed a coordinated operation of regenerative braking and mechanical braking. Adequacy of the modeling, including identification of the unmeasured torques, was verified through a comparison with experimental data.

Braking Process

Due to the increasing concern for environment protection and the uncertainty about oil reserves, nowadays electricity is playing a key role as an alternative energy source in the automotive sector. In this paper, non isolated bidirectional converter is used for electric vehicle application during regenerative braking process. During motoring operation, the converter supplies energy to motor through battery. In regenerative braking action, the converter supplies the available back emf to charge the battery. The recycled energy is effectively stored in the battery. The simulation is carried out in MATLAB/Simulink. The worthiness of simulation is illustrated experimentally by developing a prototype. The simulation and experimental results are presented in this paper<strong>.</strong>
