Dynamic Modeling And Energy Analysis On Series Hybrid Electric Vehicle

With the rapid development of the world's automobile industry, China's automobile industry has entered a boom period. But the widespread use of motor vehicles caused serious environmental pollution and energy shortage problem, Energy and Environment has become an urgent need for governments to resolve the issue of sustainable development strategy, Hybrid electric vehicles becomes one of the feasible technologies to solve this problem with its characteristic features. And optimize and improve the hybrid system control strategy is an important method to improve the fuel economy and reducing emissions.Virtual prototyping technology is an important way to model and analysis mechanical system dynamics. This paper first takes ADAMS as the example, analysis the ideas and features of multi-body system dynamics modeling software, and then establishment the multi-body dynamic model of hybrid vehicles needed for this study; And control strategy is the core of the whole hybrid system, is the key technologies of the hybrid system achieves low power consumption, low pollution, and high degree of automation. this paper combined the key technologies of hybrid control strategy—energy distribution, regenerative braking and so on, Determine use"the engine power to follow as the main control mode, and with thermostat control mode"as the control strategy. And create the control strategy simulation model in the platform MATLAB/SIMULINK. And successfully import the control strategies and ADAMS in the kinetic model into ADVISOR, create series hybrid electric vehicle system, and carried out simulation analysis. Form the simulation, we can find that the vehicle can get requirement power according to this control strategy, at the same time the battery working condition also can be controlled better than before. Effectively avoid frequent charging and discharging of the battery, and also can ensure the engine is working in the fuel economic zone.
