Published 2020-01-13 by SAE International in United States
Nowadays, develop and launch a new product in the market is hard to every company. When we talk about a launch new vehicle to the customers, this task could be considered more difficult than other products whether imagine how fast the technology should be integrated to vehicle. There are main pillars to be considered in this scenario: low cost, design, innovation, competitiveness and safety. Whereas Brazilian economic scenario, all OEM has to be aware to opportunity to make the product profitable and keep acceptable quality. This combination between low cost and quality could be broken or not distributed equally between the pillars. Based on that, in some cases could have a quality broken that will affect directly the customer. This paper will focus on project to define of the new ignition switch, when the main challenge to achieve the cost reduction target was defined to change a material to electrical terminals. Beyond the material definition, we will discuss about the validation in component level and VOW, quality indicators (internal and external), prevent reoccurrences actions and…

Basic technical requirements for ballistic safety to guarantee the quality of civilian automotive armoring services in Brazil

Polytechnic School of University of Sao Paulo-Guido Muzio Candido, Paulo Carlos Kaminski
  • Technical Paper
  • 2019-36-0329
Published 2020-01-13 by SAE International in United States
Brazil is the largest civilian armored vehicle market in the world with more than 16,000 new protected units produced in 2018, followed by Mexico with 7,000 automobiles, according to Brazilian Army (BA) data. In this context, this paper presents an overview of Brazilian market for civilian vehicle armoring, definitions and characteristics of transparent and opaque ballistic resistance protective materials according to U. S. Department of Justice, the National Institute of Justice, NIJ Standard 0108.01. Based on this premises, the paper addresses basic technical requirements for ballistic safety in design and process to guarantee minimum quality of armoring services. The purpose of this paper is to safeguard the original features and functionality of the automotive components while simultaneously providing recommended ballistic protection of the vehicle with quality. The adoption of minimum automotive quality management system requirements from IATF 16949 International Automotive Task Force, in armoring services with different types of vehicle models and brands, will encourage to reduce tack time production, to improve vehicle armored quality, to reduce final reworks, to keep original equipment guarantees, to…

Commercial vehicle pedal feeling comfort ranges definition

Ford Motor Company-Wesley Bolognesi Prado, Silvia Faria Iombriller, Marco André Rodrigues da Silva, Lázaro Renato Oliveira
  • Technical Paper
  • 2019-36-0016
Published 2020-01-13 by SAE International in United States
The brake pedal is the brake system component that the driver fundamentally has contact and through its action wait the response of the whole system. Each OEM defines during vehicle conceptualization the behavior of brake pedal that characterizes the pedal feel that in general reflects not only the characteristic from that vehicle but also from the entire brand.Technically, the term known as Pedal Feel means the relation between the force applied on the pedal, the pedal travel and the deceleration achieved by the vehicle. Such relation curves are also analyzed in conjunction with objective analysis sheets where the vehicle brake behavior is analyzed in test track considering different deceleration conditions, force and pedal travel.On technical literature, it is possible to find some data and studies considering the hydraulic brakes behavior. However, for pneumatic brake systems, the pedal feel theoretical study is not usual, where is normally used for these developments, exclusively the subjective evaluation which become necessary to have more specialists to define the brake pedal behavior.Throughout this article will be revised the characteristics concepts…

Unsettled Domains Concerning Autonomous System Validation and Verification Processes

EllectroCrafts Aerospace-Fabio Alonso da Silva
  • Research Report
  • EPR2019012
Published 2019-12-30 by SAE International in United States
The Federal Aviation Administration (FAA) and the Department of Transportation’s (DOT’s) National Highway Traffic Safety Administration (NHTSA) face similar challenges regarding the regulation of autonomous systems powered by artificial intelligence (AI) algorithms that replace the human factor in the decision-making process. Validation and verification (V&V) processes contribute to implementation of correct system requirements and the development life cycle - starting with the definition of regulatory, marketing, operational, performance, and safety requirements. The V&V process is one of the steps of a development life cycle starting with the definition of regulatory, marketing, operational, performance, and safety requirements. They define what a product is, and they flow down into lower level requirements defining control architectures, hardware, and software. The industry is attempting to define regulatory requirements and a framework to gain safety clearance of such products. This report suggests a regulatory text and a safety and V&V approach from an aerospace engineering perspective assessing the replacement of the human driver from the decision-making role by a computational system. It also suggests an approach where aerospace guidelines can…

Improvement in PEMS performance for RDE testing at high and varying altitudes

HORIBA, Ltd.-Shun Fukami, Haruhisa Mohara
  • Technical Paper
  • 2019-01-2200
Published 2019-12-19 by SAE International in United States
RDE (Real Driving Emissions) by definition is performed under a wide range of conditions. Altitude, as well as temperature, is one of the boundary conditions that depends on the area where the test is performed, which will vary from country to country. These boundary conditions not only affect the exhaust emissions from the vehicle, they also affect the accuracy of the PEMS (Portable Emission Measurement System).The effect of barometric pressure changes on a PEMS was evaluated by altitude simulation chamber and means of an RDE test on Mt. Fuji. This paper describes the challenges for PEMS measurement with barometric pressure variations and the advanced system that has been developed to meet them.
