Powertrain modularity

The target of this deliverable is to define the basic sizes (continuous and peak torque and power ratings, mass, expected available packaging envelopes) of the investigated components and systems for case studies. Furthermore, a set of integrated EM-TECH corner modules and on-board electric drive solutions for electric vehicles are defined to cover the widest possible range of vehicle segments. This deliverable also describes the associated machine control such as the cooling control and the inverter control for the new machines, and the vehicle controls to exploit the benefits to vehicle performance brought by the new machines, including the wheel slip control, the motor regenerative braking and braking blending, and the anti-jerk control.

This document describes fault-tolerant control strategies for the SiC/GaN power converter and the eMotor of the RHODaS integrated motor drive (IMD). It outlines control levels within the proposed IMD, details fast response strategies for critical faults managed by the power converter control and defines fault-tolerant control to be implemented by cloud/edge computing for the IMD. The document also addresses potential faults in the power converter and electric motor, discussing feasible fault detection strategies.

This report is dedicated to the implementation of project tasks aimed at developing and validating a new generation of electric drives for automotive transport. The project considered two key technological lines: the use of In-Wheel Motors (IWM) in an e-corner configuration, and the use of axial electric machines as part of an e-axle system. The main objective of this stage was to preliminarily test the performance of individual components and subsystems, as well as to validate control algorithms in conditions close to real-life operation.

The utilization of IWMs and axial motors creates opportunities for improvements in energy-efficiency, improved dynamic characteristics, and the implementation of new vehicle motion control functions, including the distribution of traction and braking forces at the level of individual wheels. These technologies create the basis for more flexible powertrain architectures and expand the potential of integrated control systems.

The report presents the results of experimental studies conducted on assembled test benches to evaluate the correct functioning of control elements and analyse the effectiveness of the interaction between hardware and software components of the e-corner and e-axle systems.

The transition to e-mobility is disrupting the automotive market. To facilitate this transition, the European Commission with the support of the 2ZERO partnership is calling for experts to engage in collaborative R&D programs, and develop pre-competitive solutions and methodologies supporting the uptake of e-mobility. The target of this paper is to provide an overview of the granted European projects running under the umbrella of the E-VOLVE cluster, illustrating the complementarity of the different initiatives as well as their coverage of the main priorities as defined by ERTRAC. The focus is set on the targets and outcomes of the projects HiPE, HighScape, RHODaS, SCAPE, EM-TECH and Multi-Moby, addressing innovative components (power electronics, e-motors), advanced control strategies, and circularity for safe, efficient, affordable and sustainable e-mobility.
