Electrification of commercial vehicle drives
 

KOHANA

The sustainable decarbonisation of road freight transport can only be achieved by electrifying the drivetrain. The main focus is therefore on the electric motor. Not only must it be very reliable and have a long service life, but despite its performance-related size, it must also be installed in a relatively small space in the vehicle, i.e. be correspondingly compact. This requires sophisticated and often complex cooling concepts.

Together with experts from the "Electric Drives" division of the Fraunhofer Institute IFAM and other project partners such as Additive Drives GmbH and the DLR Project Management Agency, we at BPW are working on the sustainable decarbonisation of road freight transport by electrifying the drivetrain.

DATA ON SENSOR TECHNOLOGY FOR LORRY TRAILERS

CARGOTRAILSENSE_AI

The basic research at the Dortmund University of Applied Sciences has proven to be fruitful. The data collected on sensor technology in lorry trailers is so convincing that the project on load safety is being continued. 

BPW is supporting the Dortmund University of Applied Sciences as a partner. In addition to the research and test centre F&T LaSiSe gGmbH in Selm, LOG4-Consult GmbH and the city port of Lünen as well as the Dutch tyre pressure specialist Impaqed Products B.V., the suppliers Continental with Contitech Luftfedersysteme GmbH from Hanover and the network specialist OKIT GmbH from Sprockhövel have also been acquired for the second project phase.

The CargoTrailSense_AI project is developing a system for determining the wheel and axle load of lorries. Sensors not only monitor the load and its distribution, but also allow conclusions to be drawn about vehicle damage and road conditions.  _{[Source: CargoTrailSense geht in die Verlängerung | Fachhochschule Dortmund (fh-dortmund.de)]}

THE RECUPERATION AXLE OF THE FUTURE

REKUTRAX

In the "RekuTrAx" research project, BPW is working on a recuperation axle module of tomorrow that promotes CO₂ savings and sustainable transport: Universities and industry partners are jointly designing a future version of the ePower electric axle module.

The project is called "RekuTrAx" - short for "recuperation carrier axle". Four partners, including BPW, REFU Drive GmbH, the Institute for Mechatronic Systems at Leibniz University Hannover and the Karlsruhe Institute of Technology, are working together to develop a demonstrator for an intelligent recuperation axle. The aim is to prove that this can reduce the CO2 emissions of commercial vehicle fleets. The proof is provided by modelling and simulations, combined with component and system measurements.

TEST METHODS FOR ELECTRIFIED HEAVY-DUTY DRIVES 

eTESTHIL

The eTestHiL project team has set itself the task of reducing testing efforts during system integration by testing individual subsystems in the virtual overall system at an early stage. Real-time capable hardware-in-the-loop models are derived from the detailed models that are already used for model-based system development (MBSE) during product development. In this way, HiL tests can be anchored in the model-based product development process of the future in a new way.

In addition to setting up its own system test bench for drive testing, BPW supports its partners in the development of chassis and drive systems with its own expertise and contributes to the definition of standards for the testing of electric drive systems with its application knowledge.
