Periodic Reporting for period 1 - SmartCorners (User-centred Optimal Design of Electric Vehicle with Smart E-Corners)

Berichtszeitraum: 2024-01-01 bis 2025-06-30

Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

In-wheel motors (IWMs) have become a mature technology that is well-suited for new user-centric electric vehicles (EVs). IWMs can be integrated in multi-functional and controllable modules consisting of the electric powertrain, friction brake and suspension/steering actuation. By combining several vehicle functionalities in a compact solution, the modules offer substantial opportunities to enhance the design and the operation of EVs. This is the starting point of the SmartCorners project.

Using machine learning and AI, an adaptive multilayer control strategy will be implemented with historical and current data from the vehicle, its environment, and users, including relevant EV fleets. This approach will pave the way toward software-defined vehicles, enabling rightsizing, holistic optimisation, innovative fault mitigation and actuator allocation strategies as well as more efficient, adaptive, predictive, and personalised system operation.

SmartCorners is organized around the following objectives
- (O1): Accelerated design and testing methodologies of adaptable, efficient, right-sized, flexible and user-centric smart corner systems (SCS) based on in-wheel powertrains
- (O2): New series of scalable and flexible SCS for next-generation EVs
- (O3): Predictive, user-centric, AI- and model-based control solutions for SCS equipped EVs
- (O4): Holistic thermal and passenger comfort management

SmartCorners is targeting the following impact
- Societal impact: Greenhouse gas and emissions reduction in road transport through transition toward e-mobility; increased electric vehicle (EV) acceptance with overall positive environmental effect.
- Economic impact: overall cost reduction of EVs (by 5...10% depending on the vehicle segment as compared to benchmarked EVs).
- Technological impact: new design of smart corner systems as components of promising EV architectures; new methods of DT-based validation of EV technologies (with >30 % reduction of the development time).
- Scientific impact: new concepts for user-centric EVs, their novel multi-physics development as well as the relevant manufacturing decision-support framework.

In conclusion, SmartCorners will provide a significant competitive advantage for the European industry thanks to the multi-disciplinary team and participative approach.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

The following activities have been performed during the first reporting period:

Work Package 1 - Specification, conceptualisation and requirements
- Definition of the layout of the smart corner and the targeted vehicle control applications covered by SmartCorners;

While writing this report (RP1), the project results are under development; the targeted objectives have been preliminary validated (simulation, lab) but further integration and evaluation in more realistic environment is still pending (focus of the 2nd reporting period). Parallel to this, consolidation of the target groups getting benefits from SmartCorners have been performed, and a dedicated engagement strategy has been designed. The main highlights for the engagement strategy are (a) end-user survey regarding the needs for human-centric e-mobility; (b) development of value proposition canvas and business model canvas for each of the project results, and participation to Horizon Results Booster in the first project year; (c) identification of "technology ambassadors" able to support the replication of the technology for different vehicle platforms / geographical markets; (d) continuous alignment with the R&D&I ecosystem (including policy makers) through participation to relevant conferences and expert groups (e.g. TRA, RTR, E-VOLVE cluster).
