Abstract
BACKGROUND: At the present moment there become more electrobuses in big towns, and the problem of the increasing the their energy efficiency is actual in intertown traffic (that assumes stops and time limitation among stops) because of the limitated on-board capacitors.
AIMS: Development of the control signal algorithm of the accelerator pedal providing an effective energy consumption by an electrobus traction gear.
METHODS: The new method for control signal formation of the accelerator pedal is proposed. It has a feature that provides the system operation “traction gear – frequency converter” in zone of the increased efficiency factor and limits the velocity of control signal level growing when a driver tromps gas.
RESULTS: Analysis of the electrobus operation results in intertown traffic shows, that the aggregate average electric capacity, consumed at electrobus operating equipped with the energy saving systems, is less by 8,2% than at electrobus operating without energy-saving systems at the same conditions. The average efficiency factor of the “traction gear – frequency converter” system of an electrobus equipped with energy-saving systems has been increased by 4.5%. The time of driving on the route of an electrobus equipped with energy saving systems increased by 27 seconds that is an acceptable result. Energy saving in linehaul operation was provided only by an antislip system operation. During the total time driving of the electrobus energy saving was 2.6%.
CONCLUSIONS: A new method for generating a control signal from the side of the accelerator pedal is proposed, which differs in that it ensures the operation of the “traction motor – frequency converter” system in the zone of increased efficiency and limits the rate of increase in the level of the control action when the driver abruptly presses the accelerator pedal.
