OBD-II Symposium to Feature Discussions on the Challenges Faced by the Automotive Industry
The upcoming SAE 2014 On-Board Diagnostics Symposium
in Anaheim, California will feature foremost experts in the field. Governmental agencies, auto manufacturers, system and subsystem suppliers and the service industry will all weigh in on how the complexity of vehicles and the interactions between systems are creating unique challenges for everyone. More stringent rulemaking and tighter controls require unique solutions within every area of the industry. Government speakers will give updates on current rulemaking. Vehicle manufacturers will also share their individual challenges during the event.
New technologies such as 12V start-stop and alternative fuel propulsion implementation, along with new requirements such as diesel misfire are heading the list of topics. To cope with all of this, new design processes and methodologies are helping to streamline the development of such technologies. New modeling and simulation techniques allow old ideas to have fresh implementations. And, it also appears that Autosar may be coming of age and ready to start tackling some of the impending issues. Industry experts will discuss these items and more.
System and subsystem suppliers are moving ahead with more innovative designs and "smarter components" which have their own microprocessor to handle multiple functions. These components utilize communication buses to provide data to main systems rather than analog signal transfers. This cuts down on wiring requirements, which, in turn, cuts weight and cost in a vehicle. Control and monitoring of these systems will be among the topics covered in this segment.
The service industry has the difficult job of diagnosing and repairing these new technologies. Although all vehicle OBD systems are required to comply with applicable standards, anomalies do creep in from time to time. Smart systems, subsystems and components, while beneficial to ease of design, can present their own brand of challenges to the service community. Experts from the standards side and from the service side will discuss how the standards continue to evolve and how the service side of the industry works to keep up with this evolution. Individual breakout sessions will also be held for special high-interest topics.
