E-Mobility-Opportunities and Challenges of Integrated Corner Solutions
Abstract:
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).
Current e-vehicle platforms still present architectural similarities with respect
to combustion engine vehicle (e.g., centralized motor). Target of the European
project EVC1000 is to introduce corner solutions with in-wheel motors supported
by electrified chassis components (brake-by-wire, active suspension) and
advanced control strategies for full potential exploitation. Especially, it is
expected that this solution will provide more architectural freedom toward
“design-for-purpose” vehicles built for dedicated usage models, further
providing higher performances.
Target of this paper are (a) to introduce the EVC1000 project and results
achieved so far; (b) with the example of two vehicle platforms (AUDI E-tron and
JAC iEV7) to discuss platform migration opportunities and challenges related to
corner solutions, and (c) to present preliminary results (simulation based) with
respect to expected performance increase.
