Usage of Telematics Data in Advance Powertrain Development

Honda Cars India Pvt Ltd.-Shubham Garg, Anurag Anurag, Mohit Singhal, Isao Chiba, Kouji Okayasu
  • Technical Paper
  • 2019-28-2438
Published 2019-11-21 by SAE International in United States
To achieve accuracy in model development with large-scale actual customer data in low cost and limited time usage of telematics system was adopted. Honda’s OBD II diagnostic connecting device Honda Connect was used as transceiver for this telematics system, which was used as an accessory in Honda vehicles. Data collected with this device with large sample size and regional diversity across India was used in product development for Honda System. Control system development for BSVI vehicles, Idle start stop hardware specification selection and Battery electric vehicle target range study was done with Honda Connect Data.

Digital Twins for Prognostic Profiling

Altair Engineering India Pvt Ltd.-Painuri Thukaram, Sreeram Mohan
  • Technical Paper
  • 2019-28-2456
Published 2019-11-21 by SAE International in United States
Ability to have least failures in products on the field with minimum effort from the manufacturers is a major area of focus driven by Industry 4.0 initiatives. Amidst traditional methods of performing system/subsystem level tests often does not enable the complete coverage of a machine health performance predictions. This paper highlights a workable workflow that could be used as a template while considering system design especially employing Digital Twins that help in mimicking real-life scenarios early in the design cycle to increase product’s reliability as well as tend to near zero defects.With currently available disruptive technologies, systems integrated multi-domain 'mechatronics' systems operating in closed-loop/close-interaction. This poses great challenge to system health monitoring as failure of any component can trigger catastrophic system failures. It may be the reason that component failures, as per some aerospace reports, are found to be major contributing factors to aircraft loss-of-control. Essentially, it is either too expensive or impossible to monitor every component or subsystem of a complex machine and the current state of the Integrated Health Monitoring Systems seem to…

Correlation of Noise Emitted by vehicle on an External Pass-By Noise Track and Indoor Anechoic Chamber

International Centre for Automotive Technology-Ikshit Shrivastava
  • Technical Paper
  • 2019-28-2425
Published 2019-11-21 by SAE International in United States
Ikshit Shrivastava1, Kiranpreet Singh2 1,2 International Centre for Automotive Technology (ICAT), Gurugram, India Introduction: Pass By Noise emitted by the vehicle is one of the most critical tests for certification is vehicle worldwide. There are a number of national and international regulations to define test procedure. Though the available tracks are constructed to meet the requirements of these test standards, but there are other external parameters viz. ambient temperature, barometric pressure, wind speed and its direction, affecting the measurements. These parameters are beyond the control of human and this contamination of test data results in longer test time to monitor atmospheric/ambient conditions and perform the test. Indoor pass-by noise testing is a comparatively new method of testing, which is yet to be evaluated for repeatability/correlation with conventional exterior pass-by noise testing. Objective: This paper aims to establish a correlation between exterior pass-by noise testing and indoor pass-by noise testing. This correlation will serve to establish a foundation for future developments in automobiles; and, evaluate the use of indoor pass-by noise testing as an acceptable alternative…

The Road to Automobility

Autonomous Vehicle Engineering: December 2019

Lawrence D. Burns
  • Magazine Article
  • 19AVEP11_03
Published 2019-11-01 by SAE International in United States

The era of electrified, self-driving vehicles is upon us. Engineers are key to the transformation - with much hard work still to be done.

In 1911, eight years after the Wright Brothers flew the first airplane, French general Ferdinand Foch dismissed the new technology. “Airplanes are interesting scientific toys,” he scoffed, “but they are of no military value.” World War I and the wave of aeronautical progress it triggered would prove Foch wrong. Today, automobility is the subject of a “hype or ripe” debate similar in spirit to what the airplane experienced in its nascent years.

FCA claims North America's most-advanced driving simulator

Automotive Engineering: November/December 2019

  • 19AUTP11_09
Published 2019-11-01 by SAE International in United States

FCA recently inaugurated what it's billing as the most advanced driving simulator in North America at its Automotive Research and Development Centre (ARDC) in Windsor, Ontario. The new Vehicle Dynamics Simulator (VDS) provides nine degrees of freedom and driver-specific calibrations to emulate a vehicle's driving behavior on a wide range of surfaces and environments. The new hardware-in-the-loop test bench will permit iterating a host of simulated systems between concept and prototype phases to improve the overall product experience.

Published 2019-11-01 by SAE International in United States

GM Propulsion engineers elevate the evergreen small-block V8 to new heights for its mid-engine Corvette mission.

Instead of heaving decades of small-block V8 expertise out the window, GM Propulsion engineers led by chief engineer Jordan Lee leveraged past success to create a new-for-2020 V8. Known as the LT2, the 6.2-L V8 gives Chevy's all-new, eighth-generation 2020 Corvette more power (the most yet in the base Stingray), stirring response, and competitive fuel efficiency compared with the outgoing C7.

Calculation of Drag Torque Losses by Component of a Transfer Case

Magna Powertrain of America, Inc.-Ricardo Rivera Rodriguez, Carlos Martinez
Published 2019-10-22 by SAE International in United States
In recent decades, fuel economy has become a key indicator of an automaker corporate social responsibility and a market differentiation factor, and ultimately it is regulated by government agencies such as EPA through CO2 emissions compliance tests. The light pick-up truck and SUV production share has been increasing in the last few years, being 4-wheel drive capability one of the main features that customers seek. Within the 4-Wheel Drive system, the transfer case has a significant impact to both torque transfer efficiency and parasitic losses. The scope of this paper is to better understand the parasitic losses of a transfer case by the quantification of its individual drag losses by component. At product development phases, one measurement of interest is the system level spin loss which has a target value defined by the automakers, and contribution by component is often neglected if the system has the expected performance. This study summarizes the tests performed on a 2-speed chain driven transfer case, where as a first step, a baseline spin loss measurement was taken, then the…

Systematic Work Flow for Fatigue Life Prediction of Automotive Components

Mahindra & Mahindra, Ltd.-Nitin Kumar Khanna, Baskar Anthonysamy, Krishna Shettipally, Manohar Kalal
Published 2019-10-11 by SAE International in United States
Fatigue life estimation of automotive components is a critical requirement for product design and development. Automotive companies are under tremendous pressure to launch new vehicles within short duration because of customer’s changing preferences. There is a necessity to have a comprehensive virtual simulation and robust validation process to evaluate durability of vehicle as per customer usage. Test track and field test are two of the most time-consuming activities, so there is a need of simulation process to substitute these requirements. This paper summarizes the overall process of Accelerated Durability Test with measured road loads. Based on category of vehicle, type road profiles and the customer usage pattern, the wheel forces, strains and acceleration are measured which is used to derive the equivalent duty cycles on proving ground. The wheel force transducers (WFT) are used to derive loads for fatigue life estimation. A full vehicle model is prepared in ADAMS CAR and validated through Physical testing. The loads on suspension hard points extracted from the validated MBD model. These loads at various hardpoint locations, are used…
