As we transition towards Internet of Things (IoT) - humans are connected to each other & outside world through the smartphone. Customers tend to use smartphones for varied purposes ranging from communication to entertainment. However, the concern of distraction exists due to poor visibility & accessibility of the phone's screen in driving condition. One of the repercussion of being connected to smartphone particularly in driving condition includes higher number of road accidents due to distraction. This paper explains one of the key initiatives taken by Maruti Suzuki India Limited to address the same. This is done by offering an entry level connected infotainment system which comprises of the following three components: (a) An entry-level infotainment with basic display & vehicle connectivity, (b) A Dock mounted on infotainment panel enabling safe usage of smartphone due to its position i.e. accessibly and visibility in driving condition, (c) A Driving App specifically designed for driving usage where one can access calling, messaging, navigation on the go with a vibrant UI & easy to use gestures. The infotainment unit…

Driveline NVH Integration of An NA Truck Program

American Axle & Manufacturing-Ying Peng, Zhenghong Shi, Christopher Folts, Gregory Kopp, Zhaohui Sun, Alexander Sandstrom
Published 2019-06-05 by SAE International in United States
In the current automotive industry, it is common that the driveline subsystem and components are normally from different automotive suppliers for OEMs. In order to ensure proper system integration and successful development of driveline system NVH performances, collaboration efforts between OEMs and suppliers are very demanding and important.In this paper, a process is presented to achieve successfulness in developing and optimizing vehicle integration through effective teamwork between a driveline supplier and a major OEM. The development process includes multiple critical steps. They include target development and roll down, targets being specific and measurable, comprehension of interactions of driveline and vehicle dynamics, accurate definition of sensitivity, proper deployment of modal mapping strategy, which requires open data sharing; and system dynamics and optimization. More specially, the supplier can work with OEM to seek the most cost-effective solutions, through tuning the driveline system dynamics to provide "quiet" frequency zone against vehicle sensitivity, to avoid normally needed costly suspension changes. Two case studies of a pick-up vehicle driveline program integration are used in this paper to illustrate the effectiveness…

NVH Aspects of Electric Drive Unit Development and Vehicle Integration

FEV Europe GmbH-Christoph Steffens, Peter Janssen
FEV North America, Inc.-Thomas Wellmann, Todd Tousignant, Kiran Govindswamy, Dean Tomazic
Published 2019-06-05 by SAE International in United States
The automotive industry continues to develop new powertrain and vehicle technologies aimed at reducing overall vehicle-level fuel consumption. Specifically, the use of electrified propulsion systems is expected to play an increasingly important role in helping OEM’s meet fleet CO2 reduction targets for 2025 and beyond. This will also include a strong growth in the global demand for electric drive units (EDUs).The change from conventional vehicles to vehicles propelled by EDUs leads to a reduction in overall vehicle exterior and interior noise levels, especially during low-speed vehicle operation. Despite the overall noise levels being low, the NVH behavior of such vehicles can be objectionable due to the presence of tonal noise coming from electric machines and geartrain components as well as relatively high shares of road/wind noise. In order to ensure customer acceptance of electrically propelled vehicles, it is imperative that these NVH challenges are understood and solved.This paper discusses various aspects of the EDU NVH development process. This will include a discussion of the NVH target cascading methodologies for EDUs, followed by a description of…

An Innovative Test System for Holistic Vehicle Dynamics Testing

FKFS-Jens Neubeck
MTS Systems Corp.-Ford Boone, Wilbur Kan
Published 2019-04-02 by SAE International in United States
In the automotive industry, there is a continued need to improve the development process and handle the increasing complexity of the overall vehicle system. One major step in this process is a comprehensive and complementary approach to both simulation and testing. Knowledge of the overall dynamic vehicle behavior is becoming increasingly important for the development of new control concepts such as integrated vehicle dynamics control aiming to improve handling quality and ride comfort. However, with current well-established test systems, only separated and isolated aspects of vehicle dynamics can be evaluated.To address these challenges and further merge the link between simulation and testing, the Institute of Internal Combustion Engines and Automotive Engineering (IVK), University of Stuttgart is introducing a new Handling Roadway (HRW) Test System in cooperation with The Research Institute of Automotive Engineering and Vehicle Engines Stuttgart (FKFS) and MTS Systems Corporation. The HRW allows testing of a vehicle’s combined longitudinal, lateral and vertical characteristics and therefore provides the possibility to supplement road testing with integrated vehicle testing under laboratory conditions.IVK, FKFS and MTS agreed…

Data Interoperability for Aerospace IVHM Systems

Infosys-Ravi Kumar G. V. V.
SAP-Martin Whitfield
Published 2019-03-19 by SAE International in United States
Aerospace systems today are generating a lot of data and for the most part all this data is being generated by siloed entities (by various stakeholders like components/sub-system manufacturers, OEMs, operators) and ends up living within the four walls of these individual entities. For the industry to fully benefit from this data there needs to be a transparent way to share this data while strictly controlling the proprietary nature of the data and adhering to all contracts. The SAE HM-1 technical committee is writing an aerospace information report (AIR) 6904 to describe a digital data landscape and approach that can support health management [1]. Integrated vehicle health management (IVHM) systems cut across many disciplines and boundaries and can benefit from structured landscape and well defined approach. For example, data associated with a fault in an aircraft subsystem like the engine must travel through multiple systems and boundaries before it can be analyzed by the cognizant personnel. Today the landscape is pretty ad-hoc; with not many standards governing the data handling, storage, analysis, and disposal. This…

Applicable Aircraft Integrated Vehicle Health Management (IVHM) Regulations, Policy, and Guidance

HM-1 Integrated Vehicle Health Management Committee
  • Aerospace Standard
  • AIR6900
  • Current
Published 2019-01-14 by SAE International in United States
This AIR lists and describes a collection of regulations, policy, and guidance documents applicable to design approval applicants, aircraft operating certificate holders, and maintenance repair and overhaul (MRO) organizations. The aircraft industry should consider these rules when installing IVHM technology for use in aircraft maintenance. This is a starting basis and should not be considered as complete when certification of an IVHM system is expected. The AIR’s objectives are: 1 To set the foundation for aircraft certification applicants seeking to design IVHM solutions as part of the type certificate (TC), supplemental type certificate (STC), amended TC, or amended STC activities; and 2 To set the foundation for aircraft operating certificate holders to engage with regulators to get authorization for using IVHM applications as part of an aircraft maintenance program. NOTE: This AIR’s scope is limited to the United States (U.S.) Federal Aviation Administration (FAA) information only in this version, but future revisions intend to include other regulator input.
