An Hybrid Observer for a two-branch Supercapacitor Model : voltages estimation for SOH and SOC under NEDC and WLTP cycles

International Conference on Control, Decision and Information Technologies
In this paper, based on a two-branch model, an online internal voltages estimation method of a supercapacitor is proposed. The goal is to provide a fast and accurate online estimation of such voltages as they are useful for estimating its State Of Health

The influence of wheel and tire aerodynamics in WLTP

2015
The geometric shape of passenger car wheels can have a large influence on the aerodynamic drag of a vehicle as it has been shown already in different publications. In combination, tire and rim cause approximately 25% of the overall drag. Until now, the challenge for aerodynamicists is to find the rim / tire combination with the best aerodynamic ...

Impacts of WLTP Test Procedure on Fuel Consumption Estimation of Common Electrified Powertrains

SAE Technical Paper Series, 2019
<div class="section abstract"><div class="htmlview paragraph">The new European test procedure, called the worldwide harmonized light vehicle test procedure (WLTP), deviates in some details from the current NEDC-based test which will have an impact on the determination of the official EU fuel consumption values for the new vehicles.

Contribution of tires and wheels to the WLTP

2019
Starting in 1997, all fuel consumption and emission values in Europe were based on the so-called “New European Driving Cycle (NEDC)”. Although this cycle did not represent the typical vehicle-driver related fuel consumption values, it was very suitable for comparing cars and engines.

Influence of Fuel Properties on GDI PM Emissions Over First 200 Seconds of WLTP Using an Engine Dynamometer and Novel “Virtual Drivetrain” Software

, 2020
The influence of fuel properties on particulate matter (PM) emissions from a catalytic gasoline particulate filter (GPF) equipped gasoline direct injection (GDI) engine were investigated using novel “virtual drivetrain” software and an engine mated to ...

The challenges of WLTP emission regulations from the vehicle manufacturer’s point of view

2020
Sustainability is one of the basic principles of the Daimler AG corporate strategy and a benchmark for its success concerning the entire value chain - from suppliers to products. A central aspect of Mercedes-Benz Cars is the “path to zero-emission driving” that merges three paths leading to the future of mobility: the combination of very efficient high-
