In the light commercial vehicle (LCV) segment, almost exclusively Diesel engines are used today. The reasons are high mileage, low real-world fuel consumption, high loading capacity and therefore low total cost of ownership. In the next decade, very demanding CO2 targets as well as more stringent legal requirements for pollutant and noise emissions, especially in urban areas, require a substantial increase of electrified powertrain concepts. LCVs are typically employed for freight and passenger transport within urban areas, but are also used in interurban and/or motorway operation. These diverse cases of operation are often not suitable for full electric powertrain concepts, limiting their large-scale introduction. In this context, a Diesel Hybrid powertrain represents a highly capable and flexible propulsion system with attractively low real-world fuel consumption and the ability to achieve ultra-low pollutant emissions.

    The potential of such a Diesel Hybrid powertrain for LCVs is investigated in a joint research project between FEV and VW. For this purpose, a demonstrator vehicle has been set-up with a P02 hybrid topology. The P02 hybrid topology is selected to be able to emulate different hybrid systems as well as different levels of hybridization from a 48V Mild Hybrid to a high voltage Plug-In Hybrid. The paper discusses future legal boundary conditions and describes the concept definition, the demonstrator vehicle setup as well as first vehicle results. The investigations are supported by simulation model calculations focusing on dedicated operating strategy optimization and an evaluation of the CO2 and pollutant emission reduction potential for different use cases in the LCV segment.
