  2. 1. Energy consumption prediction and routing for electric commercial vehicles

    Author : Rafael Basso; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian Inference; Machine Learning; Energy Consumption; Green Logistics; Reinforcement Learning; Electric Vehicles; Vehicle Routing; Eco-Routing;

    Abstract : With the recent growing interest for electric vehicles as one of the initiatives to help tackle pollution and climate change, several opportunities and challenges emerge. This kind of vehicle releases no tailpipe emissions, is quieter, more energy efficient in terms of tank-to-wheels and simpler, which can lead to less maintenance. READ MORE

  4. 2. Micro-structural based acoustic modelling of anisotropic open cell materials

    Author : Eva Lundberg; Huina Mao; Bradley Semeniuk; Peter Göransson; Mathieu Gaborit; Romain Rumpler; Peter Göransson; Elke Deckers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound absorption; vehicle; anisotropic; foam; micro-structure; resource efficient; transfer matrix method; ljudabsorption; anisotrop; skum; mikrostruktur; TMM; fordon; resurseffektiv; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : A method for the calculation of the acoustic performance of open-cell foammaterials is discussed. From a known micro-structural geometry and theconstituent material, the relevant acoustic properties are computed using apreviously published analytical method for the calculation of the dynamicdrag impedance and a previously published method for the calculation of theelastic moduli.

  5. 3. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

    Author : Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

    Abstract : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. READ MORE

  6. 4. On Noise Generation and Dynamic Transmission Error of Gears

    Author : Mats Henriksson; Leping Feng; Reader Andy Moorhouse; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Acoustics; Akustik;

    Abstract : Noise from heavy trucks is an important environmental issue. Several sources contribute to the total noise level of a vehicle, such as the engine, gearbox, tires, etc. The tonal noise from the gearbox can be very disturbing for the driver, even if the noise level from the gearbox is lower than the total noise level.

  7. 5. Roadblocks to Implement Electric Freight Transports : Challenges for Commercial Vehicle Manufacturers and Hauliers

    Author : Jorge Gutiérrez Chiriboga; Magnus Blinge; Maria Huge-Brodin; Uni Sallnäs; Lisa Govik; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The freight transport industry is crucial for the global economy and a key element of all supply chains and logistics systems. The demand for freight is expected to more than double over the next three decades. Freight transport’s externalities and negative impact on the environment have been highlighted in previous research and reports. READ MORE
