System design for advanced CVTs

System Design of Advanced CVTs | VDI workshop

Unique in this form worldwide, the VDI System Design of Advanced CVTs workshop is solely concerned with the integration of continuously variable transmissions (CVT) in electrified powertrains. The workshop covers this topic in detail, looking at everything from the system through to the component level. In the process, you’ll learn about the benefits of CVTs as well as mastering challenges they present when integrated into electrified powertrains.

A ‘stepless’ transmission for the electrified powertrain

Almost all major automotive manufacturers have announced that they are focusing on electric vehicles in the medium to long term. This makes electrified powertrains increasingly relevant. With their ‘stepless’ operation, continuously variable transmissions (CVT) play an important role. The most significant benefit in this case is the high level of efficiency. However, developers are also faced with the challenge of integrating CVTs into electrified powertrains as a result of their influence on the design and dimensioning of other subsystems.

The international VDI System Design of Advanced CVTs workshop will present you with relevant concepts for CVTs as well as control system design and new actuator concepts. Further highlights include innovative design ideas to optimize variators and the electric drive as well as the fundamentals of thermal and electrical management. After this workshop, you’ll be in the position to better determine what you need to look out for when integrating continuously variable transmissions in electric powertrains on a systemic and component level.

This workshop is the ideal accompaniment to the VDI conference “CVT in automotive Applications”. Profit from a reduced combination price if you book both events together.
