]]> Parallel Hybrid Electric Vehicle Energy Management Strategy Optimization

the integration of traditional fuel vehicles replica fendi handbags and pure electric vehicles advantages hybrid cars

With global energy and environmental issues have become increasingly prominent, the development of low fuel consumption, low emissions of new cars become the primary task of the development of todays automotive industry. In this context, the integration of traditional fuel vehicles and pure electric vehicles advantages hybrid cars become the most promising low emission, low power cars.

Much energy as a new source of transportation, hybrid vehicles used in the performance of its energy management strategy are closely related. Meet the dynamic performance of the car, under the premise energy management strategy should be according to the characteristics of automotive power systems and real time operating conditions, to achieve in the engine, the motor torque distribution between the rational, to get maximum fuel economy performance of the vehicle, Low emissions and smooth driving performance. Hybrid vehicle energy management problem is a nonlinear dynamic optimization involves an important issue that affect vehicle performance and as a hybrid of the industrialization process of a major bottleneck, so far have not been finally resolved, need to overcome.

Because the hybrid system is an integrated electrical, mechanical, chemical and thermodynamic systems of nonlinear dynamic system, itself and its coordination between the various components is extremely complex, difficult to establish precise mathematical model system; while the vehicle driving conditions and the randomness of pilot operation, which also increases the difficulty of designing energy management strategy. In this paper, a parallel hybrid car for several major problems of energy management strategy, combining fuzzy control technology, neural networks, clustering algorithms, multi objective optimization and other related knowledge further study and optimize and improve , the main work is as follows: First introduced topic background, the current development of hybrid vehicles and its key technologies, highlighting the hybrid vehicle energy management strategy research status, energy management strategy for the problems that the energy management strategy optimization and improvement is to improve the performance of key hybrid cars.

Analysis of the parallel hybrid vehicle operating mode and its energy management strategies to control thoughts, then one configuration for metal belt type continuously variable transmission CVT for parallel hybrid vehicles to engine efficiency graphs and battery charge Discharge resistance curve as the main basis, we propose a method based on dynamic logic threshold energy management strategy. By setting a variable threshold parameter, based on real time vehicle parameters to achieve a hybrid system for different operating modes switching, and to determine the different operating modes of the main components in the power system optimum operating curve reasonable control transfer between the engine and the motor torque distribution and the CVT speed ratio, thereby improving vehicle performance.

Instantaneous optimization of traditional energy management strategy were analyzed to determine the impact of the energy distribution of the four main factors that will optimize energy management strategy instantaneous sum for a group of four input single output energy management rules. Then the fuzzy C means clustering for offline simulation to get the energy management rules are classified as samples to train BP neural network, the establishment of energy management for neural network controller, which is proposed based on BP neural network parallel hybrid cars real energy management strategy. Simulation results show that, based on neural networks, real time energy management strategy can effectively reduce fuel consumption, but also significantly improves the energy management in real time.

For parallel hybrid vehicle is widely used fuzzy energy management strategy a number of problems were further research, we propose a fuzzy particle swarm optimization based energy management strategy. First, the establishment of a hybrid powertrain torque demand and batteries state of charge SOC as input, engine torque command output fuzzy controller for hybrid system energy distribution, and the fuzzy interfaces, database, rule base and Sharpen interface design work for analysis and gives a reasonable solution.

Then for the membership function of the fuzzy controller and fuzzy control rules rely mainly on the selection of expert experience, with greater subjectivity and other defects, using particle swarm optimization fuzzy controller fuzzy membership function parameters and control rules. Finally, the simulation experiment shows that PSO based fuzzy energy management strategies and non optimized fuzzy energy management strategy, compared to more effectively reduce fuel consumption, and can well control the battery pack SOC changes.

]]> Based on competitive financial strategy management research

replica fendi bags Strengthen strategic management has become the current trend

Survival of the fittest is the basic rules of market competition, business requirements may survive and develop, not only have the daily management of scientific fine, but more far sighted strategic vision and strategic thinking. Strengthen strategic management has become the current trend and fashion management community, with suitable financial strategy management is also becoming increasingly influenced by financial theory and practical circles unprecedented attention.

However, with relatively mature and prosperous compared to the strategic management discipline, strategic management of financial history is not long, the results are not many, but, in the management of the relevant financial strategy works, most of the works only from one aspect of the financial Discussion the companys financial strategy, strategic management issues for financial research focuses on financing, investment, distribution, mergers and acquisitions and other areas of financial management, the finance, light strategy is the current financial sector financial strategy management research a common phenomenon. The author believes that the strategic concept will attempt to import the financial management and innovation, strategic thinking is the main line runs through the financial management, financial strategy management is not just for financing, investment, financial management content distribution strategic thinking, but should be a strategic perspective on the financial management of content to revisit and redefine, excavated from the strategic nature of the strategic management of financial connotation, financial management mode of thinking outside the box, follow the developments in strategic management, strategic management structures comply with the law of financial strategy management framework .

As competition Strategic Management Strategic Concept has been recognized and accepted general community, in order to enhance the competitiveness of enterprises oriented strategic management has become a major trend, therefore, create a financial strategy management system, based on the competitiveness of enterprises in the financial perspective Strategic Management is bound to be a realistic choice smooth trend.

In this thesis, the author follows the questions, analyze problems, problem-solving research ideas, theory to practice in accordance with the order expanded hierarchical, progressive research.

In the financial strategy management theory study, this paper is to solve the problem is financial strategy management in the enterprise strategic management in what position? Support the financial management of the main theoretical basic strategy What? Why core competence is to determine the main parameters of the competitiveness of enterprises ? How to determine the company’s competitive position? How to achieve competitive evaluation and strategic financial management integration? Why should carry out strategic cost management as a basis for the management of financial strategy, how to use strategic cost management to create competitive advantage? strategic management in the financial practical study, the problem to be solved is how to finance the enterprise strategic management decisions and choices scientifically determine the companys competitive strategy?

How to deal with the fierce market environment adjust the business behavior? How different stages of the life cycle of enterprises to create sustainable competitive advantage? How to create and adapt the organizations financial strategy? How leading financial strategy and organizational structure to meet the coordination lag ? how to establish effective financial strategic resource allocation model and improve financial strategy control system? how to use the control lever in the financial management of the implementation strategy for effective control? how budgetary control of resources through the effective organization? how strategic management of the financial results measured and evaluated?
