Unsettled Legal Issues Facing Automated Vehicles

University of Michigan-Ian Williams
  • Research Report
  • EPR2020005
Published 2020-02-28 by SAE International in United States
This SAE EDGE Research Report explores the many legal issues raised by the advent of automated vehicles. While promised to bring major changes to our lives, there are significant legal challenges that have to be overcome before they can see widespread use. A century’s worth of law and regulation were written with only human drivers in mind, meaning they have to be amended before machines can take the wheel. Everything from key federal safety regulations down to local parking laws will have to shift in the face of AVs. This report undertakes an examination of the AV laws of Nevada, California, Michigan, and Arizona, along with two failed federal AV bills, to better understand how lawmakers have approached the technology. States have traditionally regulated a great deal of what happens on the road, but does that still make sense in a world with AVs? Would the nascent AV industry be able to survive in a world with fifty potential sets of rules? Given the current lack of a federal AV law, state-level legislation can have…

Bosch On Board Diagnostic solutions for Motorcycles

  • Technical Paper

Published 2020-01-24 by Society of Automotive Engineers of Japan in Japan
EU OBD legislation requirements will bring new challenges for motorcycle engine control from 2020 and 2024 respectively. This paper gives a perspective on the Bosch solutions for On Board Monitoring functions to implement the legislation requirements. Specifically the approach and validation results for the monitor for Secondary Air Injection (SAI) will be highlighted. OBD is well established e.g. for passenger car systems in worldwide markets with Bosch solutions covering different system configurations and legislation requirements. While a large portion of the required OBD monitors for motorcycles can be carried over from passenger car solutions with modifications and enhancements where needed, some specific monitors had to be developed from scratch. These new monitors are required for subsystems and components which do not exist in the passenger car environment, e.g. a controlled valve between the intake manifold and engine outlet of the motorcycle to implement secondary air injection. Special focus of this presentation is on the OBD monitoring of the secondary air injection control valve, where robustness is a challenge given the boundary conditions of only binary…

Innovative Bulb for Compact Headlamps Design

General Motors Mercosur-Israel João Cancino Junior
LUMILEDS-João Guilherme Sônego, Raphael Nunes de Souza
  • Technical Paper
  • 2019-36-0066
Published 2020-01-13 by SAE International in United States
The Single beam reflector usage with H4 halogen bulb type is adopted in low cost emerging market countries that represent a very important segment for General Motors South America region.Currently, GM engineering tech centers have developed several different solutions for H4 halogen bulb reflector type that have their package, in terms of dimensions, to meet legal requirement and performance. Taking that into consideration, this new H19LL bulb development represents a great opportunity to find out an innovative new design with reduced mass and consequently cost reduction.Besides, it could allow enhancing reflectors portfolio as well as enabling Design Studio to better define customer driven theme for the vehicle appearance.

Comparison between the WLTC and the FTP-75 driving cycles applied to a 1.4 L light-duty vehicle running on ethanol

Published 2020-01-13 by SAE International in United States
The forecast scenarios regarding the environmental pollution raises a question whether the current vehicle emission certification is reliable enough to assure fleet agreement with the legal limits. Type approval tests have been performed on chassis dynamometer in order to evaluate the emission factors and fuel consumption for passenger cars. Standardized procedures such as the FTP-75 proposed in the United States (currently incorporated in the Brazilian legislation) and the Worldwide harmonized Light vehicles Test Cycle (WLTC), a transient driving cycle model designed by the European Union to overcome the shortcomings of the New European Driving Cycle (NEDC), are discussed in this paper. Both cycles were performed in a chassis dynamometer with a flex-fuel passenger car running on ethanol blend (E92W08). The driver, vehicle and fuel were kept constant so the comparison between the cycles would not be compromised. The vehicle chosen was a 1.4 dm3 displaced volume FIAT sedan with maximum power of 60 kW at 5500 rpm and maximum torque of 122 Nm at 2250 rpm. The cycle dynamics and the engine operation points were…

Who's Making the Rules in the Fast-moving AV Age?

Autonomous Vehicle Engineering: January 2020

Jennifer Dukarski

  • 20AVEP01_09
Published 2020-01-01 by SAE International in United States

The auto industry's impact on NHTSA's regulatory cadence is apparent - and it's challenging theories of rulemaking.

Even to casual observers, it's clear that the regulatory landscape for autonomous vehicles (AVs) is a void filled with uncertainty. Outside of requirements that mandate technologies often considered “enemies” of autonomy, very little work has been completed related to AVs. To fill the regulatory vacuum, NHTSA has issued several often-discussed “guidance” documents.
