New algorithm improves speed and accuracy of pedestrian detection; cascade detection + deep learning
February 08, 2016
Researchers at the University of California, San Diego have developed a pedestrian detection system that performs in near real-time (2-4 frames per second) and with higher accuracy (close to half the error) compared to existing systems. The technology, which incorporates deep learning models, could be used in “smart” vehicles, robotics and image and video search systems.
The new pedestrian detection algorithm developed by Nuno Vasconcelos, electrical engineering professor at the UC San Diego Jacobs School of Engineering, and his team combines a traditional computer vision classification architecture—cascade detection—with deep learning models.
Bosch says its haptic gas pedal can reduce fuel consumption up to 7%; safety warnings via nav and V2X systems
January 25, 2016
The automotive industry has been exploring the use of haptic gas pedal technologies as a way to reduce fuel consumption and increase safety by signaling the driver using a mechanism such as a vibration or a counterforce in the accelerator pedal. Continental announced its Accelerator Force Feedback Pedal in 2010, Frost & Sullivan anticipates wide premium-segment deployment of the active gas pedal technology post-2018 (earlier post); and Mercedes-Benz offers the technology in the C 350 PLUG-IN HYBRID (earlier post).
Bosch now says that its active gas pedal allows drivers to reduce fuel consumption by as much as 7%. This is possible because the gas pedal can be networked with other automotive functions, such as the transmission. Up to now, the only indication drivers have had of the best time to shift gear has been in the form of small arrows on the instrument display. The active gas pedal comes with the option of a palpable indication of the best time to shift gear.

IAV and Microsoft demonstrate connected highly automated driving vehicle for enhanced safety; cloud-based analytics and big data
January 11, 2016
At CES 2016 last week, IAV and Microsoft demonstrated a connected highly automated driving (CHAD) vehicle capable of connecting with the Microsoft Azure cloud and Windows 10 to enable communication that helps prevent vehicle and pedestrian accidents and increases driving comfort and convenience. This vehicle-2-x communication (V2X) connectivity approach uses data from the vehicle’s surroundings to improve smart service for convenience and enhance safety by anticipating and mitigating potential hazards.
The two demonstrated a use case pf the approach: a pedestrian with a wearable device is walking toward the road, concealed by a parked vehicle. The device is located by nearby intelligent roadside infrastructure that is connected to the Azure cloud. The CHAD vehicle then receives a V2X warning that permits the safe, convenient adjustment of its driving dynamics in order to detect and avoid the hazard.

UCLA researchers develop exceptionally strong and lightweight new metal nanocomposite
December 24, 2015
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal nanocomposite with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.
To create the super-strong but lightweight metal, the team developed a new way to disperse and stabilize nanoparticles in molten metals. They also developed a scalable manufacturing method that could pave the way for more high-performance lightweight metals. A paper on their work is published today in Nature.
Continental to demonstrate dynamic eHorizon technology during CES; Connected Energy Management and Blind Curve Warning
December 16, 2015
Continental will demonstrate its latest generation of eHorizon technology during CES next month in Las Vegas. Continental will show with two use cases based on dynamic eHorizon technology—Connected Energy Management and Blind Curve Warning—how data from the cloud can predict the road ahead, ultimately reducing fuel consumption and making vehicles safer. Both demonstrations will be conducted on public roads in Las Vegas.
Continental has already shown that the static eHorizon—introduced commercially in 2012—which uses certain data from a static map stored in the vehicle, enables a significant reduction of fuel consumption (around 3% on average). As a result of this success, Continental has taken the development of eHorizon even further by using the cloud and crowd intelligence to enhance the digital map in the dynamic eHorizon Backend with fresh and accurate information.

Caltech, JPL designed megasupramolecule fuel additive reduces intensity of post-impact fuel explosions
October 02, 2015
Researchers at Caltech and JPL used statistical mechanics to design a polymeric fuel additive that can self-assemble into “megasupramolecules” (≥5000 kg/mol) at low concentration (≤0.3 weight percent) and thus can reduce the intensity of post-impact fuel explosions that occur during accidents and terrorist acts.
Furthermore, preliminary results show that the additive can provide this benefit without adversely affecting fuel performance. The work is published in the journal Science.

J.D. Power: growing usage of safety technologies in new vehicles contributes to increasing vehicle appeal
July 24, 2015
The safety-related technologies with which manufacturers are increasingly equipping their new vehicles are making those vehicles more appealing to their owners, according to the J.D. Power 2015 US Automotive Performance, Execution and Layout (APEAL) Study.
The APEAL Study, now in its 20th year, examines how gratifying a new vehicle is to own and drive. Owners evaluate their vehicle across 77 attributes, which combine into an overall APEAL Index score that is measured on a 1,000-point scale. The overall APEAL score has increased by 4 points year over year to 798 in 2015. The study finds that some safety features can contribute to a significant boost in APEAL scores. For example, the overall score among owners of vehicles with blind-spot monitoring and warning systems is 38 points higher than among those without them.

June 05, 2015
The US Department of Transportation (USDOT) has released a summary of available vehicle-to-pedestrian (V2P) technologies. The objective of the technical scan was to review available literature and to scan existing technology to identify pedestrian collision warning applications and assess their suitability to be adopted under the Intelligent Transportation System Joint Program Office (ITS JPO) Connected Vehicle Program.
The scan and subsequent database outlines the current V2P technological landscape. In total, 86 V2P technologies have been identified. While a number of the technologies are camera-based (17), others are likely to gain traction as the broader technological landscape evolves-making more advanced devices more easily accessible and less expensive. The data base also include crowd-sourced technologies such as WAZE.
Study using real-world data finds low speed autonomous emergency braking leads to 38% reduction in rear-end crashes
May 13, 2015
A study by a team of researchers from Europe, Australia and New Zealand has found that Low Speed AEB (autonomous emergency braking) technology leads to a 38% reduction in real-world rear-end crashes. The study, published in the journal of Accident Analysis & Prevention, also found that there is no significant difference between urban and rural crash benefits. The study also concluded that Low Speed AEB technology needs widespread fitment for maximum benefits.
Autonomous Emergency Braking is one of the more promising safety technologies that is becoming increasingly common on modern passenger cars. The low speed option normally consists of an automatic brake function that operates for speeds up to 30 km/h or 50 km/h (18.6 mph and 31 mph). Previous studies have predicted significant expected benefits of AEB technology in low speed rear-end crashes but, so far, there has been little evidence that they really work.

Packaged together in an integrated system, their features help address three key areas of accident protection: preventing or mitigating rear collisions; keeping drivers within their lane; and enhancing road safety during night time driving. The systems are intended to address commonly occurring crash types according to traffic accident statistical analyses.
Opel developing eye-tracking technology to guide headlights
March 12, 2015
Engineers at Opel, in collaboration with the Technical University of Darmstadt, are developing eye-tracking technology for application in a third-generation of automotive adaptive lighting that will be introduced after the current AFL+ bi-xenon system. The concept is that the driver’s eye movements will control the direction and intensity of light.
High-performance eye-tracking systems can require 5 to 10 cameras; for the Opel system, the researchers began with a simple webcam. Focused on the driver’s head, it scanned prominent points, such as the nose and eyes, to detect movement and thereby the driver’s line of sight.
Global NCAP calls for universal application of minimum vehicle safety standards in all world markets by 2020
March 11, 2015
Millions of new cars sold in middle and low income countries fail to meet the UN’s basic safety standards for front and side impacts, according to international automotive safety watchdog Global NCAP (New Car Assessment Program). Global NCAP has released a new policy report, “Democratising Car Safety: Road Map for Safer Cars 2020”, calling for minimum vehicle safety standards to be applied universally in all world markets.
World Health Organization (WHO) figures put the annual death toll from road crashes worldwide at 1.3 million people, while up to 50 million are injured in those crashes. The global vehicle fleet reached 1 billion units in 2010 and is forecast to double in the next ten to fifteen years, with much of this increase occurring in low and middle income countries which account for 90% of total road deaths.
