Enhanced Active Safety Through Integrated Autonomous Drifting and Direct Yaw Moment Control via Nonlinear Model Predictive Control
The introduction of active safety systems and advanced driver assistance systems has enhanced the control authority over the vehicle dynamics through specialized actuators, enabling, for instance, independent wheel torque control. During emergency situations, these systems step in to aid the driver by limiting vehicle response to a stable and controllable range of low longitudinal tire slips and slip angles. This approach makes vehicle behavior predictable and manageable for the average human driver; however, it is conservative in case of driving automation. In fact, past research has shown that exceeding the operational boundaries of conventional active safety systems enables trajectories that are otherwise unattainable.
This paper presents a nonlinear model predictive controller (NMPC) for path tracking (PT), which integrates steering, front-to-total longitudinal tire force distribution, and direct yaw moment actuation, and can operate beyond the limit of handling, e.g., to induce drift, if this is beneficial to PT. Simulation results of emergency conditions in an intersection scenario highlight that the proposed solution provides significant safety improvements, when compared to the concurrent operation of PT algorithms and the current generation of vehicle stability controllers.

European Initiatives Addressing High Efficiency and Low-Cost Electric Motors for Circularity and Low use of Rare Resources
The automotive industry is amidst an unprecedented multi-faceted transition striving for more sustainable passenger mobility and freight transportation. The rise of e-mobility is coming along with energy efficiency improvements, greenhouse gas and non-exhaust emission reductions, driving/propulsion technology innovations, and a hardware-software-ratio shift in vehicle development for road-based electric vehicles. Current R&D activities are focusing on electric motor topologies and designs, sustainability, manufacturing, prototyping, and testing. This is leading to a new generation of electric motors, which is considering recyclability, reduction of (rare earth) resource usage, cost criticality, and a full product life-cycle assessment, to gain broader market penetration. This paper outlines the latest advances of multiple EU-funded research projects under the Horizon Europe framework and showcases their complementarities to address the European priorities as identified in the 2Zero SRIA. Target of this paper is to introduce a family of European projects (EM-TECH, HEFT, MAXIMA, VOLTCAR and CliMAFlux), all following the target of high efficiency and low-cost electric motors for circularity and low use of rare resources. Especially, this paper will describe the latest advances of the respective projects as well as their complementarity to address the 2Zero strategy.

Evaluating Modulation Techniques in a Hybrid T-Type Power Converter based on GaN and SiC Semiconductors for Electric Transport
Gallium nitride (GaN) and silicon carbide (SiC) semiconductors can improve the power converters used in electric vehicles. These devices offer significant advantages due to their ability to operate at high switching frequencies while maintaining high efficiency. This paper presents a comprehensive comparison of modulation techniques for hybrid T-type converters that use SiC and GaN semiconductors. The analysis compares modified sinusoidal pulse-width modulation (M-SPWM), double-signal pulse-width modulation (DSPWM), and carrier-based pulse-width modulation (CB-PWM) techniques in terms of efficiency and DC bus balancing capabilities. The study examines the normalized voltage ripple and losses on the DC bus utilizing MATLAB/Simulink and PLECS. The simulation results indicate that DSPWM and CB-PWM hold promise as viable alternatives to the traditional M-SPWM technique for electric mobility applications, particularly when the power converter operates at high switching frequencies.

Experimental results and validation of lab-scale power converters prototypes
This document provides a comprehensive report on the activities related to the experimental validation of lab-scale power converter prototypes. It includes an analysis of the current standards for power converter testing, drawing on publicly available sources and the expertise of RHODaS partners.
The document also proposes a detailed test plan for High Power Converters (HPC), which are based on Low Power Converter modules. This plan encompasses electrical tests for both Low Voltage (LV) and High Voltage (HV) parts, as well as environmental, mechanical, and safety tests. Additionally, the document reports on laboratory tests to verify basic parameters of Low Power Converters (LPC), such as efficiency, distortion, and Common Mode Voltage (CMV).
The analysis highlights the absence of comprehensive standards for inverter testing, necessitating the search for relevant documents from various testing fields. Due to the high voltage levels considered in the DC/AC converter, of at least 1000 VDC Bus, it is necessary the adaptation of research methodologies in cases where direct references are lacking. This process requires substantial knowledge and experience in test systems and application of standards.
The conclusions drawn from these activities are expected to support future design, optimization and recommendations, focusing on further improvements in power converters and the use of standards specifically adapted for them in automotive applications.

E‐gear functionality based on mechanical relays in permanent magnet synchronous machines
Permanent magnet synchronous machines (PMSMs) are still the first choice for use in electric vehicles, due to their unparalleledefficiency and power density. However, they suffer from an inherently limited speed range. As field weakening or the addition of amechanical gearbox deteriorates the efficiency of the drive, it is suggested in this paper to equip the drive with reconfigurationswitches, giving rise to a so-called e-gear. The switches—which are implemented by means of mechanical relays—allow to change the winding connection of the electric machine from a series to a parallel connection and hence to double its efficient speed range.Simulations and experimental results on a 4-kW axial-flux PMSM confirm the feasibility of the concept and prove that the reconfiguration can be conducted in less than 35 ms.
