Method for assessing the effectiveness of the use of electromechanical transmissions of vehicles at the design stage

Abstract

The vehicles equipped with electromechanical transmission due to the development of traction electric drive, as well as on-board electric energy storage became very prospective. However, at the stage of such vehicles design the difficulties associated with evaluating the energy efficiency of the developed vehicles, in particular, with the evaluation of the efficiency of traction electric vehicles arise. In this work, the authors propose a method for evaluating the efficiency of traction electric motors of newly developed electromechanical transmissions of transport vehicles, based on the construction of an empirical dependence approximating statistical data on the characteristics of existing electric motors. The data on electric motors from a number of manufacturers used in vehicle transmissions was studied for approximation. The article discusses the application of the developed method to design an algorithm for controlling the transmission of a wheeled vehicle, aimed at increasing its energy efficiency. The efficiency of the algorithm is confirmed by simulation of the dynamics of the vehicle, the initial data for the simulation were obtained during the traction-dynamic calculation. The developed simulation model together with the method of evaluating the efficiency of the electric motor made it possible to carry out a comparative assessment of the developed gearshift control algorithm and the gearshift approach, which does not take into account the dependence of the energy losses of the electric machine on the operating mode in cases of urban and mixed driving cycles. As criteria for assessing the effectiveness of the application of the developed law of control of an electromechanical transmission, the amount of energy spent on movement along a given cycle and the number of gear shifts on the route were used. The obtained results confirm the effectiveness of using the developed algorithm in the conditions of vehicle movement in an urban environment.
