Project Background
§ Future mobility scenarios for EU urban areas see a modal shift in
personal mobility from family cars to lighter, smaller and more
environmentally friendly alternatives1.
§ Besides walking and cycling, these alternatives include a range of L-
category vehicles (LVs) — with a growing share of electric.
§ Urban policies should encourage Electric LVs adoption; particularly,
four limiting factors are slowing down the diffusion of ELVs: cost,
energy efficiency, attractiveness and riders willingness to use.

passenger vehicles must be encouraged”

#3: To improve the driver experience of ELVs.
…developing a multi-wheel vehicle control algorithm that will improve
handling/stability and HMI improvements that address range anxiety…
l INCREASE RANGE by Regenerative Braking
– Driver should not perceive any difference between regenerative and “non-regenerative”
deceleration
l REDUCE RANGE ANXIETY by Smart Range Management
– Driver should feel safe and confident that the final destination can be reached within the given
battery charge
l IMPROVE DYNAMIC SAFETY by Stability Control
– dynamic behaviour similar to PTW but safety increased with two tires for each axle with a
dedicated vehicle control

interaction with the vehicle

#4: To make ELVs more attractive to car drivers…

resulting in an increase in the percentage of car drivers that consider
LVs as a viable alternative to their cars for their urban travel needs.
§ Attractive vehicles taking into account User Needs
17. This project has received funding from the [European
Union’s Horizon 2020 research and innovation
programme under grant agreement No 653511
Willingness to use is not just a matter of attractive vehicles
§ Cost: electric scooter is expected to have a purchasing price comparable to a
conventional ICE (mostly 50cc),
§ Range autonomy in real driving situation is always expected more than 60km;
§ Convenience and easy of use rather than the aesthetics are key purchasing factors,
even if constrained by current limited offer.
§ Quality: customer pays attention to the brand, especially at technical parts (i.e.
engine and battery)

Alternative strategies and
business models to be
explored
18. This project has received funding from the [European
Union’s Horizon 2020 research and innovation

Next steps
§ In-lab and track tests to assess performances and targets
resulting from simulation
§ Acceptability tests and user survey ex-post to assess
attractiveness of RESOLVE concepts
§ Refinement of cost analysis and market analysis to look for
Business Model Innovation
