The energy crisis and rising gas price in the 2000s led to a growing popularity of hybrid vehicles. Hyundai-Kia Motors has been challenging to develop the new efficient eco-technology since introducing the mild type compact hybrid electric vehicle for domestic fleet in 2004 to meet the needs of the increasing automotive-related environmental issues. Now Hyundai has recently debuted a full HEV for global market, Sonata Hybrid. This system is cost effective solution and developed with the main purpose of improving fuel consumption and providing fun to drive. Presenter Seok Joon Kim, Hyundai Motor Company

In 1991, Hino Motors, Ltd. (Hino) launched the world's first hybrid city buses in the market. Thereafter, Hino has improved its hybrid vehicle technology and applied it to various commercial vehicles including city buses, sightseeing buses, medium-duty trucks and light-duty trucks.

Presentation will concentrate on a brief overview of SAE International including history, international focus and SAE electro-mobility ground vehicle standards development activities. The new era of mobility and the driving forces behind it including converging technologies and today�s drive toward �green� will be discussed. Also, standards and technology enablers for vehicle electrification including, the global landscape for EV charging standards and next generation charging method approaches will be reviewed. Additionally, an overview of SAE global EV Battery Standards and activities including industry/government collaborative efforts to develop lithium ion rechargeable energy storage system safety standards will be provided. Presenter Keith Wilson, SAE International

Optical fiber has begun replacing copper in avionic networks. So far, however, it has been mainly restricted to non-critical applications (video transmission to the flight deck, IFE?). In order to take advantage of the high-bandwidth, low weight, no EMI properties of optical fibers in all data transmission networks, it will be necessary to improve the testing. One part of the puzzle, which is still missing, is the self-test button: the possibility to check the network and detect potential failures before they occur. The typical testing tool of a technician involved in optical fiber cables is the ?light source ? optical power meter? pair. With this tool, one can measure the insertion loss of the fiber link. A second important parameter, the return loss at each optical connector, is not analysed. In addition, this is only a global measurement, which does not allow the detection of possible weak points.

The traction motor is key to the �synergy of the electric powertrain�, the overall functionality of the battery, e-motor, power control electronics, and charging system. Therefore some automakers have decided to design, develop, and produce their traction motors in house while some others are working with suppliers for their electric power train motors. Off-the-shelf motors, no matter how extensively they are adapted for a specific application, can compromise the efficiencies of the propulsion system.

In Oct. 2011, Nissan announced its new six-year environmental plan, Nissan Green Program 2016 (NGP 2016), that includes initiatives to lead fuel efficiency: 35% fuel economy improvement compared with 2005 on a corporate average for all Nissan vehicles sold in Japan, China, Europe and the United States. To achieve this target, we`re planning to launch products delivering class-leading fuel efficiency such as an all-new FWD hybrid model, Introducing a next-generation continuously variable transmission (CVT). In this session, Nissan`s apploach for fuel erfficiency is presented with internal-conbustion powered technology evolution and hybridization, referring to new FWD hybrid system.

TAUPE is a collaborative research project co-funded by the European Commission in the framework of the Seventh Framework Programme (FP7). It addresses the aeronautic sector and is composed of 17 partners from 6 European countries. The project lasts 3,5 years (September 2008 ? February 2012), is led by Safran Engineering Services (Labinal, SAFRAN Group) and has a budget of 5.5M?. The project aims to simplify the electrical architecture of aircraft and to reduce the length and mass of cabling by introducing PLC (PowerLine Communication) or PoD (Power over Data) technologies inside the aircraft. Both technologies essentially aim to supply power and data over the same cable.

This paper proposes a current limits distribution control strategy for a parallel hybrid electric vehicle (parallel HEV) which includes an advanced powertrain concept with two electrical driving axles. One of the difficulties of an HEV powertrain with two electrical driving axles is the ability to distribute the electrical current of one high voltage battery appropriately to the two independent electrical motors. Depending on the vehicle driving condition (i.e., car maneuver) or the maximization of the entire efficiency chain of the system, a suitable control strategy is necessary. We propose an input-output feedback linearization strategy to cope with the nonlinear system subject to input constraints. This approach needs an external, state dependent saturation element, which translates the state dependent control input saturation to the new feedback linearizing input and therefore preserves the properties of the differential geometric framework.

Transmission of light through automotive topcoat and primer layers can lead to degradation of the underlying electrocoat layer and to topcoat delamination. In order to protect against this, it is critical that transmission of both ultraviolet wavelengths and certain visible wavelengths be effectively blocked by the topcoat and primer layers. The clearcoat, basecoat and primer each have their own role and combine to protect against light transmission. The transmittance of these combined layers is typically measured by the Integrating Sphere UV-Visible Spectrophotometer. It would both simplify measurement of the topcoat systems and allow better system modeling if these layers could be measured separately and combined mathematically. We demonstrate here that absorbing and reflecting pigments can be effectively modeled using the Beer-Lambert law while results for scattering pigments are consistent with the Kubelka-Munk theory.

Who are the people who know the most about the buses in your fleet? They are most likely the operators and the servicing technicians. They are also the key people whose knowledge, level of training and attitude can determine the success or failure of new powertrain technologies. Training and recruitment of both need to be held to a higher standard than we have seen in the past. I will argue that even the culture of those involved in fleet operations needs to be changed. The bar for technical competence and product knowledge needs to be raised for operators and technicians. In return managers should find ways to include them as stakeholders, investing them with both additional responsibility and accountability. This will require greater access to training and recognition of achievement. Where are the busses stored and serviced? Most likely in an all-purpose state/county/municipal service facility servicing a variety of equipment.
