Abstract:
This paper is a summary of the use of information technologies in urban passenger electric vehicles, largely based on the authors' experience in developing and implementing traction systems for trams and trolleybuses. Traction control systems of the electric vehicle are made on high performance programmable microprocessors, with PWM control algorithms for power IGBT converters and vector control methods for optimal energy consumption. Simultaneously it ensures diagnostics, monitoring and protection of all components; stores the current state of the elements; and provides information means for the driver and passengers. Besides traction, information technology is present also in forming smart or even driverless vehicles. Technologies such as GPS and Wireless Networking allows optimizing urban transport.
