DE-REX Project

In the course of the publicly funded project “DE‑REX”, the Institute for Mechatronic Systems in Mechanical Engineering (IMS) heads the consortium partners Institute for Electrical Energy Conversion, Institute for Internal Combustion Engines and Powertrain Systems (all of them TU Darmstadt), AKKA, Daimler, and MAGNA GETRAG.

The DE-REX transmission system and the electric motors were designed and two complete powertrain prototypes were manufactured and set up: one prototype was running at a powertrain test rig and the other one was integrated into a demonstrator vehicle, which is still tested and investigated in further research and development work.

2015: Designing the transmission and the electric motors, developing the control software, running the ICE at a test rig, assembly of the transmission, testing the transmission and the electric motors
2016: Testing and optimization of the control software, Set up of the powertrain for a test rig and a demo vehicle,commissioning of the entire powertrain at the test rig
2017: Mechanical, electrical and cooling integration in the demo vehicle, commissioning of the vehicle, testing and optimization of the control software in the demo vehicle.
2018: Further development of the powertrain concept.
