2、otics, Boboli 8, 02-525 Warsaw, PolandThe development process i.e. assumptions, construction, simulations and analysis of a control strategy for thehybrid drive of the vehicle mounted aerial work platform is presented in the paper. Particular attention ispaid to the development of the control system

3、 strategy ensuring appropriate energy recuperation by makinguse of energy stored in the electrochemical form. The control strategy is built up around the concept of bilevelhierarchic control system. The elevation control of the aerial work platform is assumed as the primarygoal of the control system

4、. The secondary goal of the control system is formulated in terms of tracking andkeeping the charging level of the rechargeable electrochemical accumulator in predefined limits. A control system simulation model is developed in Matlab-Simulink environment. Exemplary results of control system simulat

IntroductionThe reduction of vehicle emission has been an objective of research for many years; partly it is forced by increasingly stringent environmental legislation. The Kyot

6、o protocol, whichwas adopted at the COP3in December 1997, is aimed to decrease the green house gas emissions（GHG） by an average of 5% referring to 1990 levels. It came into force on February 16, 2005 following its ratification by Russia.Hybrid systems are now gaining attention as a means for reducin

7、g GHG emissions by improving fuel economy and energy eficiency.Market for hybrid driven vehicles is growing up dynamically sincemany years. Contemporary, eleven large car manufacturers use to deliver or to intensively develop hybrid driven vehicles. Even that is mainly focusing on passenger cars seg

8、ment, it should be stressed that the remarkable effort is undertaken to implement hybrid drives in the trucks, delivery vans and buses 1,2.WestStart-CALSTART 3, an advanced transportation technologies consortium, supported by U.S. Army National Automotive Center（NAC）, organized the pilot program as

9、part of its Hybrid Truck Users Forum （HTUF） program, to speed up and to assist hybrid commercialization. According to the forecasts elaborated by CALSTART,the hybrid driven trucks market share will grow reaching ca 9% in 2010 and near 18.5% in 2020.Still heavy duty machines and special purpose vehic

10、les are the object of possible implementation for hybrid drive solution. However there are some doubts, if that application is economically feasible.Considering passenger cars,in respect of environmental regulations,important role plays the “effect of the scale”. In case of heavy duty machines, aeri

In particular that is case of closed space areas such as factory shops, warehouses, intrinsically safe zones, etc. Here the implementation of diesel-electric drives could considerably extend possible use of that kind of equipment. Very unique and on the other side common area of services

13、 is municipal services and works used to be processed during night in the highly populated zones （street sprayer-sweepers,garbage trucks, tramway traction networks service vehicles, etc.）. It is often reported by municipalities, that the issue to be solved for that services is the level of noise gen

Another example is a hybri

16、, pick andcarry and so on.A hybrid vehicle is defined as one that has more than one source of power. Several different types of hybrid solutions have beenconsidered in the past and are still undergoing extensive research, Fig. 1.
