Towards brand-independent architectures, components and systems for next generation electrified vehicles optimised for the infrastructure. - In: SAE international journal of advances and current practices in mobility, ISSN 2641-9645, Bd. 4 (2022), 5, S. 1906-1922
E-mobility is a game changer for the automotive domain. It promises significant reduction in terms of complexity and in terms of local emissions. With falling prices and recent technological advances, the second generation of electric vehicles (EVs) that is now in production makes electromobility an affordable and viable option for more and more transport mission (people, freight). Still, major challenges for large scale deployment remain. They include higher maturity with respect to performance (e.g., range, interaction with the grid), development efficiency (e.g., time-to-market), or production costs. Additionally, an important market transformation currently occurs with the co-development of automated driving functions, connectivity, mobility-as-a-service. New opportunities arise to customize road transportation systems toward application-driven, user-centric smart mobility solutions. The target of this paper is to provide a consolidated view of several related European research programs having the common goal to develop innovative, brand-independent architectures, components and systems for next generation electrified vehicles optimised for the infrastructure under the umbrella of the E-VOLVE cluster. This regroups the projects ACHILES, SYS2WHEEL, EVC1000 introducing innovative in-wheel motors for different vehicle segments, CEVOLVER introducing optimized concepts for energy and thermal management, and Multi-Moby focusing on the development of safe, efficient and affordable urban electric vehicles.

Electric vehicle corner architecture: driving comfort evaluation using objective metrics. - In: SAE technical papers, ISSN 2688-3627, (2022), 2022-01-0921, S. 1-7
The presented paper is dedicated to the driving comfort evaluation in the case of the electric vehicle architecture with four independent wheel corners equipped with in-wheel motors (IWMs). The analysis of recent design trends for electrified road vehicles indicates that a higher degree of integration between powertrain and chassis and the shift towards a corner-based architecture promises improved energy efficiency and safety performances. However, an in-wheel-mounted electric motor noticeable increases unsprung vehicle mass, leading to some undesirable impact on chassis loads and driving comfort. As a countermeasure, a possible solution lies in integrated active corner systems, which are not limited by traditional active suspension, steer-by-wire and brake-by-wire actuators. However, it can also include actuators influencing the wheel positioning through the active camber and toe angle control. Such a corner configuration is discussed in the paper as applied to a sport utility vehicle (SUV). A new chassis design was developed and tested for this reference vehicle using multi-body dynamics simulation. The integrated operation of the active suspension and the wheel positioning control has been analyzed in this study with different driving scenarios and objective metrics for driving comfort evaluation. Additionally, handling and stability tests have also been performed to confirm that new systems do not deteriorate driving safety. The obtained results contribute to a comprehensive assessment of IWM-based architecture, formulated from a driving comfort perspective that is helpful for further designs of electric vehicle corners.

Active control of Camber and Toe angles to improve vehicle ride comfort. - In: SAE technical papers, ISSN 2688-3627, (2022), 2022-01-0920, S. 1-14
This paper is part of the European OWHEEL project. It proposes a method to improve the comfort of a vehicle by adaptively controlling the Camber and Toe angles of a rear suspension. The purpose is achieved through two actuators for each wheel, one that allows to change the Camber angle and the other the Toe angle. The control action is dynamically determined based on the error between the reference angle and the actual angles. The reference angles are not fixed over time but dynamically vary during the maneuver. The references vary with the aim of maintaining a Camber angle close to zero and a Toe angle that follows the trajectory of the vehicle during the curve. This improves the contact of the tire with the road. This solution allows the control system to be used flexibly for the different types of maneuvers that the vehicle could perform. An experimentally validated sports vehicle has been used to carry out the simulations. The original rear suspension is a Trailing-arm suspension. It has been modified via Adams Car. The simulations have been carried out using the same software in cosimulation with Simulink. The suspension has been tested through a Parallel Wheel Travel analysis and an Opposite Wheel Travel analysis. The maneuvers carried out have been two variations of Constant Radius Cornering, two variations of Fish-Hook and two variations of Swept-Sine Steer. A decrease in the vertical acceleration of the center of gravity has been achieved by controlling the Camber angle for maneuvers where a trajectory or rotation of the steering is imposed. The Toe angle control has allowed a decrease in vertical acceleration when a trajectory is imposed. In particular, the decrease of the Root Mean Square and the maximum absolute value have been obtained. These results demonstrate an improvement in Ride Comfort.
