DCT Technology for Low-torque Applications
Besides offering more comfort, modern automatic transmissions should help for lower fuel consumption. The new dual-clutch transmissions 6DCT150 and 6DCT200 with cascaded first gear layout enable efficient automation even in the high-volume segment of small passenger cars. In the first reference application, the 6DCT150 enabled fuel consumption benefit of 5 % in comparison to a five-speed manual transmission in the NEDC.

“In the Future, Everything Will be Hybrid”
One of the key topics at the 14th International CTI Symposium was DHT, a hybrid transmission designed exclusively for dedicated hybrid use. Toyota has favoured this approach for nearly 20 years. We spoke to Gerald Killmann, Vice President R&D, Toyota Motor Europe, about the future of hybrid powertrains.

“We Have Created a Modular Dedicated Hybrid Transmission”
With just a few changes to its architecture, the 2nd generation Voltec hybrid drive comes with added value in terms of increased electric range, improved NVH and new hybrid operation modes. Customer data and feedback played a crucial role in designing the Gen 2 Voltec, says Larry T. Nitz, Executive Director Transmission & Electrification at General Motors.

CTI Symposia put CVTs centre stage:
Are the benefits of stepless transmissions still underrated?
The ideal: stepless acceleration!
In high-powered electric automobiles like Tesla models or the BMW i3, drivers can feel like pilots already. For powerful, seamless acceleration right up to full speed, they simply apply full thrust.
In conventional automobiles, automatic shift transmissions use high numbers of gearsteps to map that ideal as closely as possible. As an interesting alternative, stepless transmissions are now being discussed intensively again.

DHT – a Model for the Future?
By definition, Dedicated Hybrid Transmissions (DHT) use at least two sources of propulsion: an ICE, and at least one e-machine. Without either of these sources, they are not fully functional. DHTs can offer several modes, for example serial, parallel, power-split CVT mode, all electric and ICE mode. Optionally, they do not require an additional launch element. What are the prospects for Dedicated Hybrid Transmissions?

Follow-up report on the 10th International CTI Symposium USA
Automotive Transmissions, HEV and EV Drives,
May 9 – 12 2016, Novi, Michigan
Two trends left a clear mark on this year’s 10th CTI symposium USA. Real Driving Emissions (RDE) is infl uencing development even sooner than experts anticipated just a year ago. And the new transmission category DHT (Dedicated Hybrid Transmission) is being discussed intensively as an alternative to add-on hybrids. Interest in the CTI Symposium was up yet again, with a participant headcount of 590 in this anniversary year. Continue reading
