Summary

Hybridisation of vehicles is considered to contribute to the European climate Goals. However the Price of These vehicles still is an obstacle on the way to further increase the number of these vehicles (either, full hybrid (HEV) or plug-in-hybrid (P-HEV)) on the road.
ADVICE aims at increasing the numbers of HEVs and P-HEVs up to 10% of all vehicles registered in the mid-term range. This will be achieved by focusing on a market segment called „premium class„, which covers medium class over upper medium class up to luxury vehicles and to SUVs. This segment is facing severe problems in reaching the more and more severe European CO2 targets, when running on fossil fuel only, not the least due to the considerable vehicle weight.
In ADVICE three physical demonstrator vehicles are built, ranging from mild-hybrid to full plug-in hybrid and – concerning fuel type – from gasoline to diesel-driven.
In addition, it will be shown that the whole range in between these demonstrator vehicles can be well covered by means of validated simulation, yielding a complete coverage of the whole “premium class” segment.
Besides fulfilling the energy efficiency and emission requirements of the call and limiting premium cost to 5% with respect to the best in-class non-hybrid diesel (and 15% premium for a P-HEV), particular attention is devoted to optimum drivability and drive performance, which are essential when purchasing a “premium class” vehicle and thus crucial to achieve the market penetration aimed at. All these objectives will be accomplished by:

1. Architecture level hybrid powertrain solutions suitable to be modularly applied to different segments to increase their volumes, thus reducing costs

2. Advanced (predictive) control strategies, taking advantage of future knowledge from external media and model predictive control strategies, taking the whole vehicle into account (not only the hybrid part)

3. Novel optimised approaches in the aftertreatment system

4. Newly developed high-temperature electronics, enabling novel strategies and approaches for energy- and thermal-management and

5. Multi-core processor architectures, enabling sophisticated, computationally expensive control strategies and models processed on board of the vehicles.

In addition hybrid energy storage systems (a combination of differently sized electrochemical systems or mixed electrochemical and mechanical systems) will be used to demonstrate both, energy efficiency and cost reduction. The ADVICE consortium brings together 22 participants from the whole vehicle value chain to meet these ambitious technical challenges in order to sustainably impact the market penetration of HEV and P-HEV in the European and global market.

ADVICES Overall objectives are:

1. Cost premium of 5% for mild and full hybrid and 15% for P-HEV compared to best in class non-hybrid diesel vehicles available on the market
2. Reduction of fuel consumption on WLTP cycle by 20% and 25% increase in electric driving range for P-HEV, respectively.
3. Demonstrating the vehicles’ noxious emissions RDE compliance with a 1.5 compliance factor.
4. Improvement of vehicle performance according to proper performance index and the objective assessment of driveability.
5. Verification and assessment along 3 vehicle classes and 3 hybrid vehicle architectures.
