Welcome Address

The automotive industry – and therefore also automotive transmissions and drive systems – are on the road to a new age of electrified and connected mobility. The new age will be characterised by autonomous, emission-free and connected driving and it will connect the automotive world with the digital world. In addition, there will be efficient, demand-oriented transport and mobility services, so owning a car will become superfluous for many customers. The requirements on vehicles and drive systems will change:

In addition to comfort, efficiency and charging infrastructure, IT expertise, artificial intelligence, connectivity, cloud-based operating systems for passenger cars and commercial vehicles, intelligent mobility solutions in urban traffic, sharing concepts and connected goods transport will be important factors in the development of the new mobility world while less priority will be given to number of gears, power and driving dynamics. However, how long this fundamental change will take and how conventional drive systems and fuel technologies will develop in the next years – those questions still need to be answered by the drivetrain and energy industry.

The fact is that conventional drive systems with internal combustion engine are increasingly complemented or locally replaced by electric vehicles in order to meet the demands for zero-emission transport and mobility in predictive short-distance operation in cities. It is also a fact that the share of electric vehicles will increase to up to 25 % in 2025 – as a result of a better energy density, the reduced costs of battery and electric drive components and the increasing density of charging stations. Surrounding conditions also include especially the tighter legal constraints, e.g. environmental obligations for urban traffic, lower CO2 limits and the electric vehicle quota in China and maybe also in Europe.

At present, the module and component suppliers follow the extended development portfolio of the automotive manufacturers, which – in addition to conventional drive systems – includes all types of electrified drives from 48 V mild hybrids and full hybrids to plug-in hybrids and hydrogen drive systems. However, particularly medium-sized automotive companies often wonder if and how long the diversity and complexity of multi-technology solutions, including conventional drive systems and transmissions continue to be in the focus as intense as today. What recommendations can be derived from the development trends for the investments in the drivetrain industry as well as for future-oriented teaching and research in the field of drive systems and transmissions?

At this year’s symposium, we will discuss this and further questions related to the automotive, transmission and drivetrain industry as well as new transmission, hybrid and electric drive concepts, but also production and component-related topics and problems with regard to passenger cars and commercial vehicles:

  • Change in mobility, market requirements and drive systems
  • Hybridisation through versatile DHTs (Dedicated Hybrid Transmissions) and add-on solutions with parallel structures
  • 8 V mild hybrids with different topologies and power classes
  • EV drivetrains and transmissions with high power density, high voltage systems
  • New AT, DCT, CVT and MT concepts with innovations for increase in efficiency and hybridisation
  • All-wheel drives, e.g. by combining conventional drivetrain and electric axle
  • New transmission and electric drive concepts for commercial vehicles and buses, synergies to passenger car propulsion systems
  • Compact, efficient shift and starting elements, e-clutch
  • Increase in efficiency through innovative oils, lubrication and actuation
  • Batteries: development of power and energy density as well as ageing, infrastructure strategies
  • Objectification and optimisation of the gear change, V2X operating strategies, benchmarks of transmissions and electrified systems
  • Production: EM production, function integration using additive manufacturing, thin-film sensors and energy management

The 9th CTI Young Drive Experts Award for outstanding student papers and theses in the field of transmission and drivetrain development is again of special importance this year to emphasise how important the young engineers are.

The extensive conference programme takes account of the above-mentioned variety of topics: about 100 presentations – plenary presentations and 16 parallel sessions. Mobility, drivetrain and transmission specialists will discuss the question “How will future mobility requirements change powertrain and transmission?” in the panel discussion. In addition, the Transmission Expo will take place again, our “technology market for innovations at your fingertips” with 135 exhibitors.

Together with the Introductory Day for Newcomers in advance of the main programme and the annual CTI Test Drive – to experience new developments and advancements of vehicles with different drive and transmission concepts – after the main conference days, the 16th CTI Symposium in Berlin is again an excellent forum for international transmission and drive experts to exchange opinions. It also provides a valuable status update and a glimpse into the future.

I am looking forward to your participation and to many useful discussions and ideas.

Best regards
