As the number of all-electric vehicles on our roads continues to increase, the transmission is losing importance as part of the conventional drivetrain. But in hybrid cars, on the other hand, it still has a role to play, although the development of the Dedicated Hybrid Transmission, or DHT for short, can be complex and expensive. In our ATZ interview, Dr. Axel Waldhelm from Horiba explains why the transmission is not about to become obsolete and how testing and simulation technologies from SiL to XiL are helping to keep costs and development time in check. He also points out what he would recommend to young students.
Dr.-Ing. Axel Waldhelm (born in 1982) has been Head of Global Applications and Global Business Manager Electrification at Horiba Europe GmbH in Oberursel (Germany) since 2019. After graduating in Mechanical Engineering at TU Darmstadt with a focus on automotive engineering, internal combustion engines, vehicle powertrains, product development, and forming technology, Waldhelm went on to complete his doctorate there in 2014 on the subject "Methodology for the development of a semi-empirical thermal engine model." He also led development projects for innovative technologies for the exhaust aftertreatment of diesel applications in Real Driving Emissions (RDE) applications. He began his career in 2015 at Jaguar Land Rover in the UK as Emissions Specialist in the Powertrain Test Operations Division, continuing as Manager Powertrain Capability Delivery from 2018.
