CRRC Changchun Railway Vehicles Co reportedly sparked widespread interest when it released its intelligent EMU technology platform and exhibited the CRRC intelligent EMU multimedia interactive system at the 2022 Berlin International Rail Transit Technology Exhibition on Sept 22.

The acronym EMU stands for electric multiple unit. 

According to CRRC officials, since the opening of the exhibition, more than 200 visitors have experienced intelligent EMU technology through the interactive system every day.

Many viewers showed great interest in the autonomous driving function and energy-saving and environmental protection technology of intelligent EMUs and inquired about relevant technical indicators in detail.

The intelligent EMU for the Beijing-Zhangjiakou High-speed Railway, developed by CRRC Changchun, is said to have achieved autonomous driving at a speed of 350 kilometers per hour for the first time in the world.

The EMU collects and processes information such as geographic locations and a vehicle's status by comprehensively using on-board sensors, radar, antennas and other equipment to achieve algorithm presets and decision-making judgments.

The train can realize functions such as automatic departures, automatic operations and automatic parking. This is said to reduce the work intensity of the driver by 40 percent and greatly improve operational efficiency.

The intelligent EMU platform combines advanced technologies, such as cloud computing, big data, artificial intelligence and 5G communications, to create a fault prediction and health management system.

The operating resistance of the intelligent EMU is said to be reduced by 10 percent, the weight is reduced by about 20 metric tons, while comprehensive energy consumption is reduced by about 8 percent. It is estimated that the annual electricity consumption of one train could supply 730 families for one year.
