Data Science and Machine Learning are buzzwords in our everyday lives, as is evident from its applications, such as voice recognition features in vehicles and on cell phones, automatic facial and traffic sign recognition, etc. Analyzing big data on the basis of internet searches, pattern recognition, and learning algorithms, provides deep understanding of the behaviour of processes, systems, nature, and ultimately the people. The already implementable idea of autonomous driving is nearly a reality for many drivers today with the aid of “lane keeping assistance” and “adaptive cruise control systems” in the vehicle. The drift towards connected, autonomous, and artificially intelligent systems that constantly learns from big data and is able to make best-suited decisions, is progressing in ways that is fundamental to the growth of automotive industry. The paper envisages the future of connected and- autonomous-vehicles (CAVs) as computers-on-wheels. These are pictured as sophisticated systems with sensors on board as data sources and a lot of other functions and running services to support autonomous-driving. These services are considered to be computationally expensive. The unit…

Photogrammetric Frost Roughness Measurements in Cold-Soaked Conditions

Baylor University-Taber Miyauchi, Stephen T. McClain, Tongxin Zhang, Dennis L. O'Neal
Federal Aviation Administration (FAA)-James T. Riley
Published 2019-06-10 by SAE International in United States
Cold-soaked fuel frost (CSFF) is a form of aircraft wing contamination that occurs when a vehicle caries sufficient fuel for multiple trips or take-offs and landings. Following the first trip, which may reach altitudes above 10,000 m (33,000 ft), the fuel for the subsequent trips is carried in the wing tanks and may reach temperatures below -25 °C. In certain times of the year at some airports, temperatures and humidity levels will form CSFF on the aircraft wing surfaces over the fuel tanks. Unless an exemption is granted for the specific aircraft model, aircraft are not allowed to takeoff if the wing surfaces are contaminated by frost. Because aircraft operators desire to minimize vehicle time spent at airports, aircraft manufacturers are expected to pursue designs that safely operate with CSFF at takeoff and to pursue certification exemptions for aircraft models enabling CSFF takeoffs. To assist manufacturers in the design of future aircraft and to assist regulators in evaluating certification exemption requests, more information about frost roughness characteristics and evolution in CSFF conditions is required. However,…

Runway Deicing Product Anti/Deicing Performance Assessment: Review and Future Directions

UQAC - AMIL-Jean-Denis Brassard, Caroline Laforte, Marc Mario Tremblay, Christophe Volat
Published 2019-06-10 by SAE International in United States
Every winter, northern airport operations are disrupted by heavy snowstorms and freezing precipitations. A simple snow accumulation or a thin layer of ice can affect aircraft operations (take-off, landing and taxi), and increase the risk for passengers and crew members, by rendering the runway slippery. Any deficits in deicing operations can also lead to flight delays and even cancellations that cost a lot to the industry. In order to maintain the runway and taxiway in a safe and useable condition, airport authorities use mechanical tools, but also chemical products. Chemical products available on the market for use in airports are principally in solid forms and liquid form, and are denominated as Runway Deicing Product (RDP). All of the products used in airport should meet the technical requirements of one of the two Aerospace Materials Specifications (AMS) documents: the AMS1431D Compound, Solid Runway and taxiway Deicing/Anti-icing and the AMS1435C Fluid, Generic, Deicing/Anti-icing Runways and Taxiways. Most of the products are used as freezing point depressants and are applied on snow, ice or packed snow covers to…

Assessment of Automotive Environmental Noise on Mobile Phone Hands-Free Call Quality

FEV North America, Inc.-Jeffrey Pruetz, Channing Watson, Todd Tousignant, Kiran Govindswamy
Published 2019-06-05 by SAE International in United States
Environmental noises such as wind, road, powertrain, and HVAC noise are important aspects to consider when implementing a hands-free terminal for mobile phone calling from within a car. Traditionally, these environmental noises have been exclusively considered for driver comfort; however, with the introduction of the hands-free terminals (HFT) and increasing consumer demand relative to mobile phone call quality, a broader implication of high background noise levels should be considered. HFT algorithm development and implementation can and does provide a high level of background noise suppression to mitigate these concerns, but this is often done at the expense of computational power and cumulative delay during a phone call. The more advantageous solution would be to address the problem from a source and path perspective with emphasis on reduction of noise in the frequency bands which most influence call quality performance. The assessments shown throughout this paper establish a sensitivity of HFT call quality to background noise levels based on industry-standard metrics, including those defined by International Telecommunication Union (ITU) standards. These assessments were established based on…

Structure-Borne Prediction on a Tire-Suspension Assembly Using Experimental Invariant Spindle Forces

Siemens Industry Software NV-Jesús Ortega Almirón, Fabio Bianciardi, Patrick Corbeels
Published 2019-06-05 by SAE International in United States
Road induced noise is getting more and more significant in context of the electrification of the powertrain. The automotive industry is seeking for technologies to predict the contribution of vehicle components upfront, early in the development process. Classical Transfer Path Analysis (TPA) is a well-established technique that successfully identifies the transmission paths of noise and vibration from different excitation sources to the target responses. But it has a drawback: it requires the physical availability of the full vehicle. To achieve shorter development cycles, to avoid costly time-consuming design iterations and due to the limited availability of prototypes, engineers derived a method that addresses these requirements. Component-based TPA is a relatively new structure borne substructuring approach that allows to characterize the source excitation by a set of equivalent loads (blocked forces) independently from the receiver structure and to predict its behavior when coupled to different receivers. Frequency Based Substructuring, FBS, is applied in order to obtain the coupled assembly. However, there are a number of challenges affecting its applicability, such as the proper modelling of the…

Acoustic Effects of Lightweighting in a Sport Utility Vehicle

Autoneum North America, Inc.-Andrea Lynne Frey
Published 2019-06-05 by SAE International in United States
Weight reduction is a significant concern for automotive manufacturers, and is often achieved by removing as much mass as is safe from the structure of the vehicle. This has a negative effect on the interior acoustics, which has become more and more of an issue as technology has advanced and people expect to be able to do business and consume media in their vehicles. Traditional acoustic treatment tends to be very heavy, which eliminates some of the weight savings.Recently a vehicle study was performed to determine if the current production sound package in a highly-rated sport utility vehicle could be maintained or improved while reducing the weight. This paper presents the results of that study. The study focused on road noise transmitted through the floor (carpet, rear wheelhouse inner and trunk insulation) and engine noise transmitted through the dash (dash inner). Testing was performed both at the vehicle level on the road and at the component level in the laboratory. It was found that the lightweight sound package was highly effective against road noise, but…

Advanced and cooperative vehicle (semi-) autonomous driving systems will become a necessity in the future for sustainable, convenient, and safe mobility. By utilizing Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication, a vehicle’s energy consumption can be reduced while maintaining safety and driving comfort. A holistic control strategy is presented, which in a novel way incorporates traffic lights, road speed limits, gradients, and curvature, as well as surrounding traffic and detailed powertrain characteristics into a single Model Predictive Control formulation. The performance of the system is evaluated using a realistic co-simulation toolchain representing the vehicle, driver, and road, including complex traffic conditions. The approach is valid for a wide range of scenarios, ranging from urban city driving to highways. Simulation results for a D-class passenger car with a diesel engine and an automatic transmission in an urban route show energy savings between 5% and 30% with an unchanged travel time, compared to a simulated human driver.
