The Hybrid Commercial Vehicle (HCV) project aims to develop urban buses and delivery vehicles with advanced second generation of energy efficient hybrid electric powertrains.

Sub-Project 5000 - Hybrid Van demonstrator

Partner's main objectives in SP5000 are to demonstrate the following improvements for the advanced second generation 6-ton hybrid van compared to the early second generation 5,6 t minibus and to second generation 3,5 t van:

  1. 5% fuel consumption reduction on urban cycle
  2. Payload improvement
  3. Cost reduction of at least 40% of hybrid drive train specific components
  4. Improved driveability and performance
  5. Electric air conditioning integration
  6. Noise reduction

In SP5000 data from real service usage of second generation hybrid van will be evaluated and analysed, Results from testing and extended field tests will be used to improve specific hybrid components and to optimise hybrid control strategy.

The hybrid powertrain will be optimised with focus on fuel consumption reduction, improved reliability and lower cost. Two new energy storage systems, lithium technology and supercap technology, updated electric drive system, as well improved AMT and electric auxiliaries will be developed and integrated on the demonstrator.

An electric driven air conditioning compressor will be integrated as well an optimised air conditioning system, in order to improve driver and passengers comfort without significant increasing in fuel consumption. With a smart control strategy, system energy consumption will be lowered and recovery braking energy use will be maximised for air conditioning functionality.

Specific hybrid sw parameters tuning will be performed on demonstrator to optimise driveability, noise and comfort and to maximise recovered energy during braking as for improved storage system performances in recharging phase.

The new hybrid demonstrator will be tested on road in real traffic in Genoa, Turin and Rome. Testing will be performed in order to understand the total system potential with special attention to new storage system capability and air conditioning performances.
