Summary

The EU funded project COnVENienT (complete vehicle energy-saving technologies for heavy-trucks) investigates different measures for fuel savings of long haul heavy duty trucks. The ambitious target is reducing fuel consumption by 26%. The measures comprise active aerodynamics, a friction reduced rear axle, an electrification of auxiliaries and a full hybrid electric drive train. The hybridization offers the possibility of downsizing the internal combustion engine. This article introduces the project and gives an overview about the measures of the subproject lead by DAF. The focus of the article is the theoretic fuel savings of the hybridization in combination with a downsized combustion engine. The benefit is evaluated with a simulation model. An outlook is given of the implemented measures in the prototype truck.
