RESOLVE objectives are the development of elements for powertrain, chassis and driver wellbeing/information/experience that can be applied to a wide range of Electric L-category Vehicles (ELVs).
To achieve these objectives, RESOLVE Consortium has devoted its efforts to the design and construction of two demonstrators, belonging to L2e and L6e categories, both tilting and both four wheelers.
The two prototypes developed in the project – named D1 and D2 – are tilting four wheelers equipped with full electric powertrains; they are intended as a valid and practical alternative to cars facing with increasing urban mobility needs.
They prototypes embody a new concept of mobility through a range of different but complementary solutions:
The RESOLVE project (Range of Electric SOlutions for L-category VEhicles) is made of 14 partners:
Piaggio Group (coordinator)
Technology transfer and adaptation of solutions already developed in automotive field has been carried out and implemented in vehicle demonstrators:

An innovative universal 48V battery module has been designed, suitable to different types of ELVs (Electric L-Vehicle), which can be assembled in a flexible way fitting within a customer’s vehicle.

The two prototypes developed in the project – named D1 and D2 – are tilting four wheelers equipped with full electric powertrains.
Drivetrain Management Module (DMM) is conceived to integrate all functions (inverter, battery charger, DC/DC converter and VMU) in one scalable component, to reduce design complexity and hardware development costs. On the other hand, a huge effort has been devoted to develop a generic overall software architecture. It is composed of five different software layers and designed in a modular way, providing great flexibility for vehicle management strategies to different hardware. The high-level part of the DMM management is designed in a Matlab/Simulink environment for automatic code generation and possibility of hardware/software in the loop simulation. Therefore, the strategies developed for the DMM will be used as basis for the D1 and D2 vehicle demonstrators with minimal adjustment to the specific parameters of the two vehicles, like engine torques and battery capacity.

In RESOLVE a rider-focused Human-Machine Interface has been designed and developed, which is:
Both prototypes will be exhibited at TRA Conference in Vienna (16-19 April) and at RESOLVE final event planned on April 25, 2018 in Brussels, at Arsenal premises (Chaussée De Wavre 950 – 1040 Bruxelles).
The RESOLVE Final event is public, participation is free but registration is required via this link:
