Auto braking: a quantum leap for road safety - Telegraph
It’s a familiar tale. You’re travelling in slow-moving traffic when, before you can react, the car in front stops suddenly. You slam on the brakes but it’s too late and there’s a sickening crunch as bumpers meet. It’s a minor collision, but getting the cars repaired will take time and most likely push up your insurance premium come renewal, and then there’s the ever-present threat of whiplash claims.
Such accidents could soon be a thing of the past, for those driving new cars at least, thanks to Autonomous Emergency Braking (AEB). It’s a system that uses radar, lidar (laser) or video technology to warn the driver of an impending frontal collision before priming the brakes and eventually performing an emergency stop.
Car Active eSafety systems can prevent accidents from happening & could save 6123 lives & prevent 135,834 injuries on European roads each year. In the long run we want a world where cars don’t crash.

Euro NCAP to drive availability of AEB systems for safer cars in Europe
Brussels, 13 June 2012 – Euro NCAP today publishes the results of its survey on the availability of Autonomous Emergency Braking systems in Europe and reveals that the assessment programme will include AEB technologies in its star rating from 2014.
Real world performance data suggests AEB systems can reduce accidents by up to 27%. Although the introduction of these active safety technologies is reducing road deaths and injuries, the availability of AEB in Europe is far from standardized. A recent survey undertaken by Euro NCAP reveals that AEB is completely unavailable on 79% of the car models on sale in Europe and that 66% of manufacturers do not offer an AEB system on any of their new car models.
Autonomous Emergency Braking systems can help to avoid crashes or to mitigate their severity by warning the driver and supporting his braking response and/or by applying the brakes independently. The technology generally uses forward-looking radar, lidar and video systems to provide a complete, accurate, real-time image of the road ahead.
Since 2010, several car manufacturers have been recognized for the safety benefits of their AEB systems through Euro NCAP Advanced rewards. Euro NCAP finds that premium brands such as Volvo, Infiniti and Mercedes have the best levels of standard AEB fitment, and are joined by Jaguar, Range Rover, Audi and Lexus when optional fit is also considered.
Cars in the Executive and Large Family categories have the highest level of availability, at least as an option. However, some volume sector manufacturers are showing that AEB can be offered as standard or as an affordable option on mass-market vehicles. Amongst others, Mazda, Ford, Honda and Volkswagen are selling AEB systems partly as standard or optional on some high-volume cars such as the Mazda CX-5, the Ford Focus, the Honda Civic and the VW up!. It is understood that Fiat will also make AEB a low-cost option on the new Panda in July 2012.
AEB systems are increasingly being made available as cars are replaced by new or facelifted models, such as the Mercedes-Benz A-Class, the Ford Fiesta and Ford Kuga. Michiel van Ratingen, Secretary General of Euro NCAP says ‘A faster penetration of these technologies into new cars will make it more realistic for the European Union to reach its target to cut road deaths by 50% by 2020.
Consequently, Euro NCAP has decided to include AEB assessments as part of the overall star rating from 2014 onwards and hopes that European authorities will soon require AEB as mandatory on all new vehicle types.’
Since Euro NCAP published the first safety rating in 1997, considerable efforts have been made by car manufacturers, technology providers, authorities and road operators to make cars safer. Despite an important reduction of road deaths the past 15 years, in Europe today, over 30,000 people are still killed on the road and many more are injured every year.
The inclusion of AEB systems in the Euro NCAP star rating will alert and encourage consumers to choose AEB when buying a new car as it will improve their safety, make a real difference and help them avoid or mitigate a crash. Results of Euro NCAP’s AEB survey were released today at a major event organized for the 15th anniversary of the organization at the Autoworld in Brussels. Details on the survey are available on the Euro NCAP website. Watch our AEB video and click here to check the results of the AEB survey.

Autonomous Emergency Braking
What is Autonomous Emergency Braking (AEB)?
AEB systems automatically apply the brakes to reduce speed when sensors on the vehicle identify a likely collision and the driver has not applied sufficient braking and is not attempting to steer away. The introduction of automatic braking was seen with the advent of Adaptive Cruise Control (ACC). ACC uses a radar unit mounted in the front grille to monitor the road ahead for other vehicles and obstacles and manipulates the car engine and brake controls to maintain and adjust speed to keep a safe distance from the vehicle ahead. Developments in environmental sensing technologies have improved system functionality and object detection reliability to the extent that systems can be relied upon to warn the driver in potentially dangerous situations, and intervene to apply pre-impact emergency braking to reduce collision speeds. State of the art systems are using ‘sensor fusion’, a combination of multiple sensor types (e.g. radar and camera or stereo vision cameras) to reliably identify not only other vehicles, but also pedestrians, and brake to a halt before impact to prevent low and medium speed crashes occurring altogether.

ESC, LDW, AEB technologies reduce car crashes
The Research Council for Automobile Repairs (RCAR) is an international body of insurance funded automotive research centres, whose primary goal is to reduce the human and economic costs of motor vehicle losses.
The P-Safe Working Group within RCAR is an insurer focussed research/advisory group. The aim of the group is to investigate new Primary Safety technologies (hence “P-SAFE”) entering the vehicle market and investigate their potential positive or negative influence on motor insurance claims. Vehicle safety technology is categorised into three areas; Primary, Secondary and Tertiary safety.
Secondary Safety refers to systems designed to mitigate injuries during a collision, such as airbags and seat belts.
Primary safety systems relate to technologies that help to avoid or reduce the severity of the collision.
Tertiary safety systems operate post-collision, and alert the emergency services to potential injuries.
The P-Safe group has chosen to focus on three main types of primary safety technology initially. These three technologies are Electronic Stability Control (ESC), Autonomous Emergency Braking (AEB), and Lane Departure Warning (LDW). ESC was selected because research has already shown that ESC is effective in reducing crashes. AEB and LDW were selected because these technologies could help address commonly occurring crash types.
Overall, the most common collision types seem to be rear-end collisions, pedestrian collisions, leaving the carriageway, collision at junctions and head-on collisions. In the development of Primary Safety Systems manufacturers should consider addressing these crash types. It appears that Autonomous Emergency Braking systems (AEB) would be the most appropriate to address these collisions types, particularly for rear-end, head-on and pedestrian collisions that are most common. LDW and ESC could also offer some benefit in reducing single car leaving carriageway crashes.
Estimates from the German Insurance Association for the current AEB on the market (giving a warning of an imminent collision and automatically applying brakes) show that collisions could be reduced by around 12%. They have taken this analysis a step further to consider a hypothetical system that is not yet on the market, which can additionally address collisions at junctions with vehicles, as well as pedestrians and cyclists approaching from the sides and driving in front. This hypothetical system could reduce collisions by 46%, and this type of analysis should be used by vehicle manufacturers to guide their development of primary safety technologies in the future to meet real world need.
Thatcham researchers have made estimates based on crash frequency in the UK to estimate the effect of fleet-wide fitment of City Safety, the Low Speed Avoidance technology from Volvo. These estimates reveal that for 351,000 crashes, where the driver does not brake, the system could therefore help to prevent or mitigate the crash, which will equate to around a €1.3 billion saving in repair costs. This will also prevent around 150,000 whiplash injuries.
IIHS identified the kinds of crashes that five primary safety technologies are intended to prevent or mitigate. Two systems, AEB and LDW, show more potential to avoid or mitigate crashes, including fatal ones. Of the nearly 2.3 million crashes that occurred annually during 2002-06 and might have been prevented by frontal collision avoidance systems, more than 7,000 involved occupant deaths. If this feature, assuming full fleet fitment on passenger vehicles, could prevent half of these crashes, the safety potential would be substantial.
Previous research by IIHS evaluated rumble strips, finding they reduce head-on crashes and oncoming side-swipes as well as run-off-the-road crashes by 25-30%. If lane departure warning works as well as rumble strips, more than 100,000 collisions per year and 2,500 deaths could be prevented when all vehicles have this feature.
