Honda Motor Co., Ltd. plans to begin public road demonstration testing of its driving support system utilizing traffic signal information next month. The demonstration testing will be conducted in Utsunomiya City, Tochigi Prefecture in Japan in collaboration with the Tochigi Prefectural Police and UTMS Society of Japan, as part of research and development of the Universal Traffic Management Systems (UTMS) in which Honda has been participating.
UTMS is a new traffic management system promoted by the National Police Agency of Japan as a part of Intelligent Transport Systems (ITS). The UTMS utilizes information communication technologies to realize safer and smoother traffic as well as to promote environmental protection. Honda’s large-scale road testing will help it verify the overall functionality and effectiveness of the system as the final stage of verification toward commercialization.
Honda recalls Fit Hybrids and Vezel Hybrids in Japan; 3rd recall due to problems with 7-speed DCT
February 10, 2014
Honda Motor Co., Ltd. announced a voluntary recall of the all-new Fit Hybrid (earlier post) and Vezel Hybrid (earlier post) produced in Japan from July 2013 through February 2014 due to a problem with the software program controlling the 7-speed dual clutch transmission (DCT) which could cause non-engagement of gears, a delay in the ability to begin driving or the inability to move at all. Honda notified Japan’s Ministry of Land, Infrastructure, Transport and Tourism of the recall with a total recall population of 81,353 units.
Honda conducted two earlier recalls in October and December 2013 due to a defect with the software program controlling the 7-speed DCT which could have caused a delay in the ability to drive the vehicle or the inability to drive. This latest recall is this the third related to problems with the 7-speed DCT. Each recall was due to a different cause.
Japan automakers going slow with biodiesel; JAMA maintains stance on B5 as maximum for now
January 22, 2014
The Japan Automobile Manufacturers Association (JAMA) is maintaining its stance on B5 (5% biodiesel, i.e., fatty acid methyl ester, blends) as the maximum until further findings and market observations on the use of B7 are reported.
JAMA bases its postion on the results of study from the Japan Auto-Oil Program subsidized by Japan’s Ministry of Economy, Trade and Industry (METI). JATOP was organized by the Japan Petroleum Energy Center to develop automotive and fuel technologies best suited to simultaneously settle three issues—“Reducing CO2 emissions”; “Fuel diversification” and “Reducing motor vehicle emissions”—and to develop high accuracy air quality simulation models and facilitating their exploitation.

November 12, 2013
Mazda is suspending all test drives intended to showcase the accident avoidance features of Smart City Brake Support until the cause of an accident with injuries in Japan involving the technology has been established and countermeasures taken.
On 10 November, there was an accident causing injury to a customer and a dealership employee during a test drive event to demonstrate safety features using a Mazda CX-5. The demonstration was organized and held by a company called Sakata Jidosha Kogyo, which runs three Mazda Autozam dealerships in Japan’s Saitama prefecture.
Toyota, Nissan, Honda and Mitsubishi to provide financial assistance for EV charging infrastructure in Japan
Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation have agreed on the details of specific financial assistance they will provide to installers of charging stations for electric vehicles (PHVs, PHEVs, and EVs). This announcement follows an agreement the four companies announced in July jointly to promote the construction of a user-friendly network of charging infrastructures. (Earlier post.)
In order for electric vehicles to become widely adopted, the partners point out, it is imperative that charging infrastructure be made widely available as quickly as possible. By assisting installers with the part of their costs not covered by government subsidies, the four companies intend to promote wider availability of chargers to make electric vehicle use more convenient.

A team from Japan’s RIKEN, led by Hye Ryung Byon, has developed a lithium-iodine (Li-I2) battery system with a significantly higher energy density than conventional lithium-ion batteries. RIKEN is Japan’s largest research organization, with institutes and centers in locations throughout Japan.
In a paper published in Nature Communications, they report that aqueous lithium-iodine batteries based on the triiodide/iodide redox reaction show high battery performance. The high solubility of triiodide/iodide redox couples results in an energy density of ~ 0.33 kWh kg−1. The reversible redox reaction without the formation of resistive solid products promotes rechargeability, demonstrating 100 cycles with negligible capacity fading.
