OPTIMISING THE OPERATIONAL PARAMETERS OF A HYBRID BUS DRIVE IN ORDER TO MINIMIZE FUEL CONSUMPTION
Regenerative braking in vehicles which are operated mainly in transient state offers the basic possibility of reducing the fuel consumption. Vehicles developed for that purpose have not fulfilled these hopes, some of them even show a higher fuel consumption. This study shows that fuel can only be saved if: the efficiency degree of regenerative braking is at its highest, the efficiency degree of energy conversion, and transmission from the fuel tank to the driving axle is improved or at least not worse than that of a conventional driving system--control of energy flows within the system is optimised by means of an adequate operational strategy. Application of these principles in conceiving a hybrid drive system for public transport city buses lead to considerable fuel saving of 22% in test runs. Acceleration, driving comfort, exhaust gas and noise emission were clearly improved.
