Řídicí a informační systém pro elektrické jednostopé vozidlo

Abstract

This thesis deals with a development of control and information system and a production of prototype of electric wheeled vehicle with an emphasis on a use of brushless engine with permanent magnets and battery which us a power source. The developed control system allows to configure parameters of the vehicle by an operator, which also will have necessary information, such as speed, distance travelled, or process temperature diplayed. Data from a battery management system (BMS), such as the range of actual capacity of the battery, instantaneous power and more, can be displayed as well. A display unit has been chosen based on experimental parameters which had been obtained during operation of the vehicle, especially the legibility under various light conditions was crucial. The vehicle is equipped with a standard speed control, reverse options and premium functions such as cruise control, lights and horn. The main contribution of this thesis is the creation of an electric two-stage gear, which works on rarely used principle when an engine is switching between star configuration and triangle configuration.
