Abstract Many vehicle subsystems were in essence mechatronic (electro-mechanical) designs. Modern vehicles have various subsystems which provide mechanical movements which were controlled by electronic and electrical systems. At the same time, they collect and track data about system performance and environmental conditions for on board diagnostics. Advances in mechanical, electrical, and embedded systems were making vehicles more intelligent. However, these mechatronics systems face new challenges including design for compliance and ensuring that all product specifications are transferred into the company's product data management system. This is especially important for electrical and electronic subsystems since they have to comply with ongoing changes related to the management of hazardous substances. Since modern vehicles were being manufactured in a global environment through outsourcing of many different components, this poses challenges with material tracking. Environmental regulations were not only different from country to country but were also constantly changing making it essential that systems are flexible and customizable.

Abstract This paper details the development process and model architecture used in the University of Washington's EcoCAR 2 hybrid supervisory controller. The EcoCAR 2 project challenges 15 universities across North America to create a hybrid vehicle that most effectively minimizes emissions and fuel consumption while still maintaining consumer acceptability. The supervisory controller for the University of Washington was designed to distribute torque to the various electric and combustion drive systems on a parallel though the road plug-in hybrid electric vehicle using Simulink and Stateflow. The graphical interface of Simulink offers some distinct advantages over text-based programming languages. However, there are also significant challenges posed by the software, particularly when several controls engineers are working in parallel on a large model with some type of version control. In order to address some of these challenges, it is necessary to structure the model so that different areas of the program are properly partitioned to avoid instances of conflicting changes from different developers.

Into the DEAP The Distributed Electrical Aerospace Propulsion project looks toward a future optimized integrated propulsion system that will allow cleaner, quieter, and more efficient performance to be incorporated into a radically innovative airframe that will feature enclosed electrically powered fans. Managing the deluge of data The model-based development (MBD) process has been a key enabler of technical advancement in the transportation industry; however, the MBD process leads to the generation of large volumes of data artifacts and work products. To maintain efficiency while continuously improving the quality of products, it is necessary to be able to manage this data in an efficient manner.

This SAE Recommended Practice is applicable to all E/E systems on MD and HD vehicles. The terms defined are largely focused on compression-ignited and spark-ignited engines. Specific applications of this document include diagnostic, service and repair manuals, bulletins and updates, training manuals, repair data bases, under-hood emission labels, and emission certification applications. This document focuses on diagnostic terms, definitions, abbreviations, and acronyms applicable to E/E systems. It also covers mechanical systems which require definition. Nothing in this document should be construed as prohibiting the introduction of a term, abbreviation, or acronym not covered by this document. The use and appropriate updating of this document is strongly encouraged. Certain terms have already been in common use and are readily understood by manufacturers and technicians, but do not follow the methodology of this document. To preserve this understanding, these terms were included and have been identified with the footnote (2), "previous usage," so they will not erroneously serve as a precedent in the construction of new names.

Racecar data acquisition used to be limited to well-funded teams in high-profile championships. Today, the cost of electronics has decreased dramatically, making them available to everyone. But the cost of any data acquisition system is a waste of money if the recorded data is not interpreted correctly. This book, updated from the best-selling 2008 edition, contains techniques for analyzing data recorded by any vehicle's data acquisition system. It details how to measure the performance of the vehicle and driver, what can be learned from it, and how this information can be used to advantage next time the vehicle hits the track. Such information is invaluable to racing engineers and managers, race teams, and racing data analysts in all motorsports. Whether measuring the performance of a Formula One racecar or that of a road-legal street car on the local drag strip, the dynamics of vehicles and their drivers remain the same. Identical analysis techniques apply. Some race series have restricted data logging to decrease the team’s running budgets.

This SAE Standard covers the measurement of radio frequency radiated emissions and immunity. Each part details the requirements for a specific type of electromagnetic compatibility (EMC) test and the applicable frequency range of the test method. The methods are applicable to a vehicle, boat, machine or device powered by an internal combustion engine or battery powered electric motor. Operation of all engines or motors (main and auxiliary) of a vehicle, boat, machine or device is included. All equipment normally operating when the vehicle, boat, machine or device is in operation is included. Operator controlled equipment is included or excluded as specified in the individual document parts. As a special case, CISPR 12 applies to battery powered floor finishing equipment, but robot carpet sweepers are excluded. By reference, IEC CISPR 12 and CISPR 25 are adopted as the standards for the measurement of vehicle emissions. In the event that an amendment is made or a new edition is published, the new IEC document shall become part of this standard six months after the publication of the IEC document.

What's New at ConExpo/IFPE A preview of some of the new products and technologies that companies plan to showcase at this year's ConExpo-Con/Agg, which is co-located with the IFPE fluid-power event in Las Vegas from March 4-8. Injection strategies for improving emissions characteristics Premixed charge compression ignition reduces NOx and soot emissions, but requires the optimization of the injection timing and pressure, fuel mass in pilot injection, and EG R rate. Systems that talk together, are efficient together Design teams take a holistic view, linking engines, transmissions, hydraulics, and aftertreatment systems to boost efficiency and performance.
