Digital design

Developments of the digital twinning framework for electric drive design in the EU-funded project EM-TECH. 

Details about the distributed XIL testing methodology out of the research of the EU-funded project EM-TECH. 

This report D2.4 is related to T2.4 where comprehensive simulation activities are carried out to assess the vehicle performance improvement resulting from the EM-TECH motor solutions: 1) the modular motor solution is assessed through a wide range of vehicle applications; 2) the high-efficient motor solution is demonstrated from WLTP drive cycle simulation, supported by advanced pulse and glide (PnG) control and brake blending strategy for further energy consumption reduction and also supported by virtual motor temperature sensor; 3) the E-gear IWM solution is evaluated by optimal gear shifting strategies; 4) the rapid-response motor solution is leveraged by an advanced anti-brake system (ABS) and traction control (TC) development. It is demonstrated that the simulation toolchain developed in D2.4 has been instrumental in advancing the EM-TECH project. By enabling the integration, evaluation, and continuous refinement of cutting-edge e-axle and e-corner technologies, the toolchain has provided valuable insights into vehicle-level performance. It effectively assesses the impact of design decisions on energy efficiency, thermal behaviour, and advanced vehicle control strategies, such as pulse-and-glide, ABS, TC, gear-shifting, and virtual sensing techniques, under both WLTP and real-world operation conditions. The toolchain has successfully bridged the gap between component-level development and vehicle-level performance assessment, ensuring alignment with technical requirements and design objectives. Its flexibility in supporting rapid updates and re-parameterisation has been crucial in accommodating advancements from component suppliers, thus promoting strong collaboration among project partners.
