Behavior Modeling and Simulation of Double Wheeled Electric Vehicle Drive

The principle of the electric vehicle is very simple: instead of an internal combustion engine with fuel stored in a tank and whose power is transmitted to the wheels through a gearbox, electric vehicle (EV) is powered by a traction system consisting of a central or two-wheel drive supplied by batteries, whose speed is controlled by an electronic control device. The propulsion system considered in this work is two driving wheels. It consists of two permanent magnet DC motors (PMDCM) directly coupled to the rear wheels of the vehicle forming a motor-wheel (driving wheel). Each motor-wheel is supplied by a static converter which is powered by batteries. The two sub systems (source-converter-motor) are coupled to an electronic differential in order to compensate the tendencies of direction of the vehicle and maintain a steady speed by adjusting the difference in speed of each motor-wheel according to the direction in the case of a turn.

W pojazdach elektrycznych stosuje się niekiedy system podwójnego napędu z elektronicznym sterowaniem. System składa się z dwóch silników prądu stałego bezpośrednio dołączonych do tylnych kół. (Modelowanie właściwości i symulacja pojazdu elektrycznego z napędem na oba koła)
