Survey of power management control technologies for HEVs and PHEVs suggests future need to consider vehicle as part of larger system
April 11, 2014
A comprehensive survey of major power management control algorithms for hybrid-electric (HEVs) and plug-in hybrid electric vehicles (PHEVs) proposes that future work will need to consider the vehicle as part of a larger system which can be optimized at an even larger scale.
This type of large-scale optimization will require the acquisition and processing of additional information from the driver and conditions outside the vehicle itself, suggests Dr. Andreas Malikopoulos, Deputy Director of the Urban Dynamics Institute and an Alvin M. Weinberg Fellow in the Energy and Transportation Science Division with Oak Ridge National Laboratory (ORNL).

CEN and ETSI deliver first set of standards for Cooperative Intelligent Transport Systems (C-ITS) in Europe
February 18, 2014
Standards organizations CEN and ETSI recently confirmed, at the 6th ETSI workshop on ITS in Berlin, that the basic set of standards for Cooperative Intelligence Transport Systems (C-ITS), as requested by the European Commission in 2009, have now been adopted and issued. The Release 1 specifications developed by CEN and ETSI will enable vehicles made by different manufacturers to communicate with each other and with the road infrastructure systems.
When they have been applied by vehicle manufacturers, the new specifications should contribute to preventing road accidents by providing warning messages, for example about driving the wrong way or possible collisions at intersections, as well as advance warnings of roadworks, traffic jams and other potential risks to road safety. This vision of safe and intelligent mobility can be achieved by utilizing wireless communication technologies to link vehicles and infrastructure and identify potential risks in real time.

Nissan project in Beijing demonstrates Dynamic Route Guidance reduces fuel consumption and CO2 emissions
September 13, 2013
Results from Nissan’s New Traffic Information System Model Project in Beijing (earlier post) have demonstrated that Dynamic Route Guidance System (DRGS) can help alleviate traffic congestion and reduce fuel consumption. A simulation based on the project results suggested that when 10% of all traffic in Beijing used DRGS, due to reduced traffic congestion, travel speed throughout the city would increase by approximately 10% and both fuel consumption and CO2 emissions would decrease by approximately 10%.
DRDS distributes real-time traffic information from the traffic information center to onboard devices via telematics; the onboard devices show drivers the fastest route on the display. This large-scale project, involving 12,000 vehicles, is the first to demonstrate and measure traffic dispersion effects in a real setting.

New roadside scattering model to improve vehicle-to-vehicle communication for intelligent transportation systems
July 17, 2013
Researchers from Trinity College (Connecticut), North Carlina State University (NCSU) and General Motors (GM) have developed a model to improve the clarity of the vehicle-to-vehicle (V2V) transmissions needed to realize an intelligent transportation system.
V2V communication relies on transmitting data via radio frequencies in a specific band. However, the transmission is complicated by the fact that both the transmitter and the receiver are in motion—and by the reflected radio waves, or radio echoes, that bounce off of passing objects (scattering objects). These variables can distort the signal, causing errors in the data.

DOT to award up to $45M for vehicle-to-infrastructure application projects
May 03, 2013
The US Department of Transportation (DOT) is soliciting (FOA DTFH61-13-RA-00004) applications for cooperative pre-competitive projects designed to enable the successful deployment of vehicle-to-infrastructure (V2I) crash avoidance and driver information applications in passenger vehicles. Projects will last 60 months; estimated total program funding is up to $45 million.
V2I applications are those applications which vehicle-based sensors and vehicle-to-vehicle (V2V) communications are not considered adequate for development of information, alerts, or warnings for drivers. These V2I applications require additional information from the infrastructure to be enabled. These applications, however, are vehicle-based, in that they are programs resident in the on-board equipment of the vehicle.
