WP1 will provides the blocks on which subsequent WPs will build. It specifies the holistic concept of ESPRIT as an innovative light weight electric vehicle, embedded within a system which will meet the changing mobility and accessibility lifestyles of Europeans at a price affordable to all. The WP specifies the requirements that will address the market needs for ESPRIT, the ‘public vehicle’ ESPRIT system; and the specifications needed for the vehicle itself and its safety performance.
WP2 will design, implement and deliver 6 coupling devices (3 for prototypes, 3 for additionally test
carrier/chassis) and the necessary guiding control command system to enable automatic coupling to the road train.. This is a particularly critical subsystem in the concept, because a coupling failure, or the failure of communication would generate some critical situations in terms of safety. In terms of coupling, the Scharfenberg principle will be preferred, although other useable coupling principles could also be envisaged. The guiding control command system consists of perception components to enable a precise approach (sensor systems) and an algorithm which controls the automatic coupling process in communication with the other relevant subsystems.
WP3 will define the system for controlling steering, braking and the powertrain of the ESPRIT vehicle, in terms of hardware and control laws. It deals with several challenges linked to the vehicle architecture (prevention of lateral oscillations, of jack knifing, or trajectory drift, reverse gear in road train condition). It will also with the implementation of a braking energy recovery strategy.
WP4 will define and develop all the components of the electronics architecture and ensure the necessary interfaces with the physical components that are to be controlled. The complex algorithms for the various control systems are developed for both single vehicle and the more challenging road train configuration. All activities related to the batteries are also located in this WP.
WP5 will perform the vehicle integrator role, defining the vehicle architecture in liaison with the other work packages and bring together all the systems of the ESPRIT vehicle into the chassis and bodywork that will have been designed in this WP. WP5 will also provide all the auxiliary systems for the vehicle body. The crash modelling simulation activities will also be performed in this WP.
WP6 will study all relevant, existing standards and directives, homologation conditions and technical specifications, applicable to electric vehicles and specific to the ESPRIT vehicle concept. Gaps will be identified and an approach to making the necessary changes to existing regulations defined. WP6 will also be responsible for performing all the basic and advanced functional tests of the ESPRIT vehicle to ensure that the required functional safety levels have been reached. All sub-system tests will be performed in their respective WPs.
WP7 will build the Operation and Business Model Simulation Tool which integrates several specific models to provide predictions on ridership and revenue of ESPRIT, optimised operation of the ESPRIT system with the collection and redistribution of the vehicles and the energy consumption and predicts operating costs, profit and revenue. It will also model the induced modal share for public transport.
WP8 will manage the dissemination and demonstration activities of the project and will prepare for the exploitation of the ESPRIT concept beyond the project’s end.
WP9 will be responsible for performing the strategic and operational management of the project including risk management.
