When vehicles share certain information wirelessly via Dedicated Short Range Communications (DSRC), they enable a new layer of electronic vehicle safety that, when needed, can generate warnings to drivers and even initiate automatic preventive actions. Vehicle location and velocity provided by Global Navigation Systems (GNSS), including GPS, are key in allowing vehicle path estimation. GNSS is effective in accurately determining a vehicle's location coordinates in most driving environments, but its performance suffers from obstructions in dense urban environments. To combat this, augmentations to GNSS are being contemplated and tested. This testing has been typically done using a reference GNSS system complimented by expensive military-grade inertial sensors, which can still fail to provide adequate reference performance in certain environments. This paper proposes a test procedure for locating systems that uses data from traditional geodetic static land surveys as the main component of the truth reference. The advantages of this approach are that it is effective in even the most challenging environments and it offers potential cost savings. The procedure is illustrated using data from an application of this approach in a dense urban area.

Revisions to the California OBD-II diesel regulations required many updates to various SAE and ISO on-board diagnostic standards; these include major revisions to SAE J1979, J1699-3, J2012 and J1930. This presentation is intended to review the background for these changes as well as the revisions made in these documents. Presenter Robert Gruszczynski, Volkswagen of America

“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. In the episode “Diagnostics and Prognostics: Proactive Maintenance and Failure Prevention” (21:04), Delphi engineers explain how they leverage the growing number of sensors and computing power in vehicles to diagnose and proactively solve emerging mechanical or electronic problems, before a breakdown occurs. This video also looks at the next generation of automotive telematics, with HEM Data demonstrating how in-vehicle data acquisition is used to monitor the inner workings of vehicles.
