Towards Design of Sustainable Smart Mobility Services through a Cloud Platform

Ford Motor Company-Dominique Meroux, Cassandra Telenko, Zhen Jiang, Yan Fu
  • Technical Paper
  • 2020-01-1048
To be published on 2020-04-14 by SAE International in United States
People and their communities are looking for transportation solutions that reduce travel time, improve well-being and accessibility, and reduce emissions and traffic congestion. Although new mobility services like ridesharing advertise improvements in these areas, closer inspection has revealed a discrepancy between industry claims and reality. Mobility service providers have the opportunity to leverage connected vehicle and connected device data through cloud-based APIs. We propose a CO2 data analytics framework that functions on top of a cloud platform to provide unique system-level perspectives on operating transportation services, from procuring the most environmentally and people friendly vehicles to scheduling and designing the services based on data insights. The motivation behind such an approach is two-fold: first, quantification enables transparency to build trust between the mobility service provider and their constituent communities; and second, identifying and acting to improve sustainability improves profitability. Using a benchmark problem with real-world vehicle and mobile device data, we demonstrate the functionality of our CO2 analytics framework.

Characterization and Durability of Mold-In-Color Engineering Plastics

Mahindra & Mahindra, Ltd.-Sandeep Kumar Shukla
  • Technical Paper
  • 2019-28-2542
Published 2019-11-21 by SAE International in United States
Plastics are prone to photo oxidative and thermal oxidative degradation under usage conditions due to their chemical nature. From sustainability and cost standpoint, there is an increasing focus on Mold-In-Color (MIC) plastic materials. Simultaneously customer’s expectations on the perceived quality of these MIC parts has been increasing with attractive color and glossy appearance.A study was conducted to analyze the product quality and durability aspects over a prolonged exposure to accelerated weathering condition. Material selected for this study were injection molded specimens of ABS and PC-ABS used in automotive passenger vehicles.Comparative analysis was conducted before and after weathering exposure at defined intervals by using Fourier Transform infra-red spectrometer (FTIR), differential scanning colorimetry (DSC), universal testing machine (UTM), Izod impact tester and microscope to understand the impact on their chemical and mechanical properties.

Life Cycle Assessment of a Passenger Vehicle to Analyze the Environmental Impacts Using Cradle to Grave Approach

Mahindra Research Valley-Rahul Lalwani, Saravanan N, Arunmozhi Veeraputhiran, IlavarasIi D
  • Technical Paper
  • 2019-28-2581
Published 2019-11-21 by SAE International in United States
Climate change is primary driver in the current discussions on CO2 reduction in the automotive industry. Current Type approval emissions tests (BS III, BS IV) covers only tailpipe emissions, however the emissions produced in upstream and downstream processes (e.g. raw material sourcing, manufacturing, transportation, vehicle usage, recycle phases) are not considered in the evaluation. The objective of this project is to assess the environmental impact of the product considering all stages of the life cycle, understand the real opportunities to reduce environmental impact across the product life cycle. As a part of environmental sustainability journey in business value chain, lifecycle assessment (LCA) technique helps to understand the environmental impact categories. To measure overall impact, a cradle to grave approach helps to assess entire life cycle impact throughout various stages. LCA is a technique to assess environmental impacts associated with all the stages of a product's life from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, disposal or recycling. A study was conducted on a passenger vehicle for life cycle assessment as…

Development and Testing of Electric Microcar for Indian Cities

VNR VJIET-Amjad Shaik, Srinivasa Rao Talluri, Raju Tappa, Ramu Ratlavath
Published 2019-10-11 by SAE International in United States
Population growth, rapid urbanisation and compounding effects of adding personal vehicles have resulted in increasing the urban air pollution in major Indian cities. Apart from the rising concerns about the urban air pollution, the increasing traffic and lack of parking space difficulties are promoting energy efficient small vehicles. Hence, there is a need to develop a new environmental friendly microcar that relatively affordable and easily manoeuvrable in bigger cities. Electric microcar is one of the most promising options to improve the near term sustainability for personal transportation in cities. This paper mainly presents the development of two seater electric microcar suitable for city driving requirements followed by road test. A mathematical modelling with reference to the urban cycle (Part-one) of modified Indian driving cycle (MIDC) is also carried out for the evaluation of energy and power requirements of electric microcar. The developed electric microcar has been tested on road with the help of the MIDC simulator kit. Results revealed that the developed prototype has demonstrated about 50 km range after one full charge.

Increase of Compressor Performance through the Use of Microstructures

Bionic Surface Technologies GmbH-Mikel Garcia de Albeniz, Peter Adrian Leitl
RINA-Emiliano Costa, Stefano Barberis
Published 2019-10-07 by SAE International in United States
Turbomachinery efficiency is becoming more and more relevant in order to reduce fuel consumption and mechanical wear of machines at the purpose of increasing their environmental sustainability and reliability. Optimized material identification and design is therefore of paramount importance. This paper describes how turbomachines can be optimized thanks to the effect of microstructures suitably created over the shapes of their constituting components in order to increase the overall efficiency via a simple coating solution. These structures, called riblets, consist of tiny streamwise grooved surfaces which are such to reduce drag in the turbulent boundary layer. Theoretical, numerical and experimental experiences gave a first estimation of the impact of riblets in industrial compressors. In this case, the riblet structures reduce the aerodynamic shear stress losses. The areas of higher interest are the diffuser and the volute, where the higher losses happen. The optimal size, position and effect on performance were analysed via simulation. The use of such an effective numerical means may give a precise evaluation about benefits in terms of efficiency increase as well as…

Frankfurt with an ‘E’

Automotive Engineering: October 2019

  • Magazine Article
  • 19AUTP10_13
Published 2019-10-01 by SAE International in United States

Early September's Frankfurt Motor Show was all about production-ready or near-production electric vehicles (EVs), as Europe's propulsion transformation gains momentum. With European Union-wide carbon-dioxide (CO2) emissions regulations closing in and societal pressure on the auto sector's contribution to climate change and sustainability, Europe's automakers-particularly those in Germany - are hastening their EV development timelines.

SEMS for Individual Trip Reports and Long-Time Measurement

Horiba Europe GmbH-Frank Heepen, Weilin Yu
Published 2019-04-02 by SAE International in United States
There is an increasing need to understand the discrepancy between the real-world driving emissions and the emissions determined from type approval in a laboratory. Currently all modern passenger cars and trucks in Europe must undergo an on-road driving emissions test with portable emissions measurement systems (PEMS). Due to the large volume and big operational effort the currently used PEMS has however the constraint for monitoring the emissions of a vehicle within a limited time. To cover as many real-world driving conditions as possible, an online measurement system with automatic functions in data taking, data transferring and data analysis is needed.A Smart Emissions Measurement System (SEMS) was developed by TNO to derive robust and reliable emission factors, this system provides a simple and easy-to-use emissions monitoring solution. Since 2012, this automotive sensor-based system and toolbox has been continuously developed and validated, through numerous measurements of emissions from light duty vehicles (LDV), heavy duty vehicles (HDV) and non-road mobile machinery (NRMM).HORIBA and TNO are collaborating on the industrialization and large-scale deployment of SEMS, enabling new possibilities for…
