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.

The goal of the project is to design, to test, and to disseminate the initial recommended framework that controls how motorists receive communications—traffic warnings, the too-close approach of another vehicle, weather warnings, or text messages—while driving. Focus will be placed on the communication’s format, visual or audible, and the order and timing of such messages.
Toyota recalling about 701,000 Gen 3 Prius vehicles in US over software issue in inverter assembly
February 12, 2014
Toyota Motor Sales, USA, Inc., is advising the National Highway Traffic Safety Administration (NHTSA) of plans to conduct voluntary safety recalls of approximately 701,000 Model Year 2010-2014 Prius vehicles to update the motor/generator control ECU and hybrid control ECU software. This is part of a global recall for the issue.
According to the information Toyota is providing Prius customers in the US, the problem resides in the Intelligent Power Module (IPM), which is inside the Hybrid Inverter Assembly. The inverter converts high-voltage direct current (DC) stored in the high-voltage (HV) battery into high-voltage alternating current (AC) for the motor/generator. It also converts AC into DC during regenerative braking for storage in the HV battery. According to Toyota, due to problems with the software, certain transistors in the IPM could become damaged when operating the vehicle under high-load driving conditions, such as accelerating during highway driving.

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.

Rice study: higher ethanol blends require different approach to deal with vapor intrusion in buildings; extreme event, low probability
December 16, 2013
A study lead by researchers at Rice University suggests that current approaches to manage the vapor intrusion risk into buildings in the vicinity of conventional fuel spills might need to be modified when dealing with some higher ethanol blend fuel (i.e., E20 up to E95) releases. The study is published in the ACS journal Environmental Science & Technology.
The basis of the concern is that ethanol-blended fuel spills usually stimulate methanogenesis in the subsurface, which could pose an explosion risk if methane accumulates in a confined space above the ground where ignitable conditions exist. The ethanol-derived methane may also increase the vapor intrusion potential of toxic fuel hydrocarbons (e.g., benzene) by stimulating the depletion of oxygen by the methanotrophs, and thus inhibiting aerobic biodegradation of hydrocarbon vapors.

|Networked sensor systems of the S 500 INTELLIGENT DRIVE research vehicle. Click to enlarge.|
Mercedes-Benz has demonstrated the feasibility of autonomous driving on both interurban and urban routes with its S 500 INTELLIGENT DRIVE research vehicle. The company set the vehicle to cover a 100 km (62-mile) route from Mannheim to Pforzheim—retracing that taken by motoring pioneer Bertha Benz exactly 125 years ago when she set off on the first long-distance drive.
The self-driving S-Class had to deal autonomously with a number of highly complex situations such as traffic lights, roundabouts, pedestrians, cyclists and trams. The successful drive was achieved with the aid of near-production-standard technology, very similar to that already found in the new E and S-Class. The project thus marks a milestone along the way that leads from the self-propelled (automobile) to the self-driving (autonomous) vehicle, the company said.

|Formulation of the overall vehicle rating according to US-NCAP based on weighted Relative Risk Scores (RRS). Source: NHTSA. Click to enlarge.|
Tesla Motors announced that in recent US-NCAP (New Car Assessment Program) testing, the Model S earned an overall 5-star safety rating from NHTSA as well as 5 stars in each component test. The Model S also earned the lowest combined total Vehicle Safety Score (VSS) achieved by any vehicle that has undergone that testing since 2011: 0.42. In this case, lower is better: VSS is essentially a weighted average risk of personal injury resulting from the different NCAP crash tests.
The NCAP crash testing is used to formulate the 5-star safety rating applied to vehicles by the National Highway Traffic Safety Administration (NHTSA). While NHTSA does not publish a star rating above 5, Tesla said that safety levels “better than 5 stars” are captured in the VSS data for the vehicles that have been tested. Based on the data, Tesla said, it achieved a combined record of “5.4 stars”. While the Model S is a sedan, it also exceeded the safety score of all SUVs and minivans, according to Tesla.
