NHTSA to move ahead with regulations for vehicle-to-vehicle communications for light vehicles
February 03, 2014
The US Department of Transportation’s (DOT) National Highway Traffic Safety Administration (NHTSA) announced it will begin taking steps to enable vehicle-to-vehicle (V2V) communication technology for light vehicles as the next generation of auto safety. This technology would improve safety by allowing vehicles to communicate and ultimately avoid many crashes altogether by exchanging basic safety data, such as speed and position, ten times per second.
DOT research indicates that safety applications using V2V technology can address a large majority of crashes involving two or more motor vehicles. With safety data such as speed and location flowing from nearby vehicles, vehicles can identify risks and provide drivers with warnings to avoid other vehicles in common crash types such as rear-end, lane change, and intersection crashes. These safety applications have been demonstrated with everyday drivers under both real-world and controlled test conditions.

|The production version of the i3. Click to enlarge.|
In a simultaneous—and video linked—unveil in New York, London and Beijing, BMW introduced the production version of its i3 battery-electric vehicle on Monday. (Earlier post.) The i3 is the first series-production vehicle out of BMW’s i brand, and is purpose-built around an electric powertrain to serve needs of megacities customers, said Dr. Norbert Reithofer, Chairman of the Board of Management of BMW AG, during his remarks in New York. With its new architecture, use of carbon fiber reinforced plastic, and premium mobility service offerings, the “i3 marks the beginning of a new mobility age,” said Dr. Reithofer.
On a full lifecycle basis, with an average European electricity mix, the i3 offers approximately a 30% lower carbon footprint over 150,000 km (93,200 miles) of use than the fuel-efficient diesel-powered BMW 118d, said Dr. Julian Weber, head of Innovation Projects e-Mobility at BMW. With a renewable electricity mix, that increases to about 50%. EVs in general currently have a larger carbon burden in the production phase than conventional vehicles (e.g., earlier post), but gain their advantage in the use phase. The crossover point for the i3 vs. the 118d is at about 50,000 km (31,000 miles), Dr. Weber said.

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.

Bosch, PSA Peugeot Citroën and partners recently presented the first two Optimal Energy Consumption and Recovery solution (OpEneR) prototypes. OpEneR is a European research project under the Seventh Framework Programme designed to increase the range of future hybrid and electric vehicles by optimizing energy management.
Launched in 2011, OpEneR is developing new driving strategies and driver assistance systems that significantly increase the efficiency, driving range, and safety of electric vehicles without increasing battery size—and thus also by limiting battery price and charging time. This is achieved by merging data from on-board and off-board sources. A particular focus lies on an optimal cooperation between the electric drivetrain and the regenerative braking system, supported by data from radar, video, satellite navigation, car-to-infrastructure and car-to-car systems.
Volvo Car Group introducing autonomous steering, other new safety and driver assistance technologies on XC90 next year
July 05, 2013
Volvo Car Group will introduce a number of safety and driver assistance technologies in the all-new Volvo XC90 at the end of 2014, including the use of autonomous steering functions to avoid accidents and make driving more comfortable, according to Thomas Broberg, Senior Safety Advisor Volvo Car Group.
Pedestrian detection at night. According to STRADA (Swedish TRaffic Accident Data Acquisition), 44% of all the pedestrian fatalities occurred in darkness, at dusk or dawn. In the US, the traffic fatality rate is 3–4 times higher in darkness (VTI). Volvo’s new Pedestrian Detection in darkness feature will enable Volvo’s detection and auto braking technology to work effectively at night. The technology includes detection and auto brake for other vehicles, pedestrians and cyclists.

Mercedes-Benz to introduce smartphone-based Car-to-X technology in production vehicles by year-end
June 17, 2013
Mercedes-Benz will introduce Car-to-X (C2X) communication technology into series production vehicles by the end of the year. Through the use of C2X communication, information on potential road traffic dangers can be passed on to drivers at an early stage so that they can take appropriate action and even help to avoid critical situations arising in the first place, the automaker noted. (Earlier post.)
As part of the initial deployment of the technology, Mercedes will use the Drive Kit Plus, which, in combination with a smartphone and the Digital DriveStyle app developed by Mercedes-Benz, turns the vehicle into a simultaneous transmitter and receiver of information.

June 10, 2013
As part of the US Safety Pilot Model Deployment of connected vehicle technologies (earlier post), the University of Michigan Transportation Research Institute (UMTRI) will launch a motorcycle study to determine how cars, trucks, buses and motorcycles interact using V2V (Vehicle-to-Vehicle) communications technology.
Two tasks will be conducted in the Safety Pilot Model Deployment Geographic Area as a proof of concept for incorporating motorcycles into the connected vehicle environment: motorcycle communications feasibility testing and motorcycle-to-vehicle performance testing. UMTRI has partnered with two motorcycle manufacturers: Honda and BMW. Australia-based Cohda Wireless is providing the V2V connected vehicle equipment.
NHTSA issues preliminary policy on development of autonomous vehicles to provide guidance to states
May 31, 2013
The US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) issued a preliminary policy statement concerning vehicle automation, including its plans for research on related safety issues and recommendations for states related to the testing, licensing, and regulation of “autonomous” or “self-driving” vehicles.
Self-driving vehicles are those in which operation of the vehicle occurs without direct driver input to control the steering, acceleration, and braking and are designed so that the driver is not expected to constantly monitor the roadway while operating in self-driving mode.

Toyota Motor Corporation (TMC) had developed and will launch in Japan the “Big Data Traffic Information Service”, a new traffic-information service utilizing “big data” including vehicle locations and speeds, road conditions, and other parameters collected and stored via telematics services.
Based on such data, traffic information, statistics and other related information can be provided to local governments and businesses to aid traffic flow improvement, provide map information services, and assist disaster relief measures. Toyota will begin accepting applications from local governments and businesses across Japan to use the service starting 3 June. Concurrently, the existing smart G-BOOK telematics service for smartphones will be upgraded to allow private users access to Big Data Traffic Information Service content.

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.
