Odpiram novo splošno temo o varnostni komponenti vozil Volvo, saj je rdeča nit vse od prvih modelov...
Za začetek prispevek o Volvo Cars Safety Center s premičnim zaletiščem.




Over 2000 crash tests performed at Volvo Cars Safety Centre

The Volvo Cars Safety Centre has performed over two thousand crash tests since its inauguration in the year 2000. The level of activity has grown over the years and ten cars per week are now tested in the crash test laboratory - one of the leading facilities of its type in the world.

The Volvo Cars Safety Centre is designed to reproduce accidents of many different kinds. The crash test laboratory is equipped with two tracks, one movable and one permanent. The movable track can be adjusted up to 90 degrees to enable tests of all kinds, from frontal to side collisions, to be carried out between cars travelling at different angles and speeds. The permanent track is long enough to enable the cars to be accelerated to speeds up to 120 km/h. A series of other tests, such as rollover accidents or collisions with animals or other objects in the surrounding environment, can also be performed.


Over 100 crash tests per model

The requirements specified by various public agencies and bodies such as EuroNCAP and IIHS represent only part of the centre's work; Volvo Cars performs additional crash tests to ensure that the collision performance of its cars is the best possible. In the course of development, a new Volvo model undergoes no less than 100 to 120 crash tests.

"To offer cars with a world-class standard of safety, we have to verify that the systems protect occupants of various sizes at a wide range of speeds and in a variety of accident situations. It is the capacity to replicate real-life accidents that makes our facility unique," explains Magnus Krokström, senior manager at the Volvo Cars Safety Centre.

In total, about 450 crash tests are carried out annually. Since the designation of the Volvo Cars Safety Centre as a Safety Centre of Excellence for the Ford Motor Company, other makes of car produced by the group - including Jaguar, Land Rover and Ford - are also tested there.


Reproduction of real-life accidents

Development and testing activities in the laboratory also involve the reconstruction of real-life accidents:

"Analysing actual road accidents and then testing new safety systems in the laboratory enables us to improve the safety of our cars, making them safer in the real traffic environment also," says Magnus.

Since new legislation, market forces and safety systems constantly present the laboratory with new challenges, it is important to maintain close contact with the researcher community to ensure that resources are allocated correctly with an eye to future developments. As an example, when planning work on the Safety Centre began back in 1996, it was foreseen that compatibility, in the context of crashes between large and small cars, would be an important area of research in the future. And so it has proved. Other types of testing that have grown in importance in recent years include rear-end collisions, which have become increasingly common in heavy urban traffic, and angled side collisions, which are a common occurrence at junctions.

"Although we have had to make some modifications since the early days, there are now almost no limits to what we can do in the laboratory," says Magnus.


Planning and follow-up

A crash test takes five days to complete. Three days are spent preparing the test car, fitting sensors and applying a matt paint, usually orange, to avoid reflections from the car while filming. The test dummies are also prepared at this time. Final preparation, including the installation of instrumentation systems and cameras, takes place the day before the actual test. On average, two crash tests are performed every day, ensuring effective use of the facility.

"Although test data can be read out within an hour, manual inspection of both car and dummies is also required. Our analysts deliver a preliminary report to the car project team within 24 hours. This is followed by a more detailed analysis that can take up to a fortnight;" says Magnus.


Virtual simulations

Computerised crash simulations are performed, using advanced computers, about three and a half years prior to the production of a new car model. Physical testing commences about a year before the model is launched on the market. Test cars used by the project team for other tests are among the vehicles used for this purpose. The cars are updated as required to make them as similar as possible to the final version. However, no physical testing is carried out unless Volvo Cars' safety experts are satisfied with the results of virtual testing.

Testing of preventive safety systems - systems that help to prevent accidents - has also begun recently. Calling for effective test methods much more advanced than the first Volvo crash test 50 years ago - when a car was rolled down a hill to hit a concrete wall - this represents one of the biggest challenges facing the Volvo Cars Safety Centre at Torslanda in Göteborg.

Morda je to, da je S80 najbolj varen. Zagotovo pa ne, da je Kia pred MB E in bmw 5.

Volvo Cars introduces new systems for alerting tired and unconcentrated drivers

* Driver Alert Control - unique technology that alerts tired and unconcentrated drivers
* Lane Departure Warning - alerts the driver if the car crosses one of the road markings without an obvious reason


Studies show that up to 90 percent of all traffic accidents are caused by driver distraction.

Now Volvo Cars introduces Driver Alert Control - with a technology solution that is a world-first in passenger cars. The system aims to alert the driver when his or her concentration level is affected, for instance during long journeys.

Another new system, Lane Departure Warning, alerts the driver if the car crosses one of the road markings without an obvious reason.

Lane Departure Warning and Driver Alert Control will be part of the same option package, called Driver Alert System. It will be available in the Volvo S80, V70 and XC70 at the end of 2007.

"Real life safety is the key to our safety philosophy. When it comes to preventive safety, we have the same approach as when we develop protective systems. In other words that our research and technical development focus on areas where new technology can create significant results in real-life-traffic," says Ingrid Skogsmo, Director of the Volvo Cars Safety Centre.

Based on the accident statistics above, Volvo Cars is focusing on developing efficient technology to help drivers avoid or reduce the severity of accidents caused by distraction and driver fatigue.


Driver Alert Control (DAC) - a unique innovation

As a result of extensive studies on how drivers operate behind the wheel, Volvo has developed Driver Alert Control - a world-first innovation that registers the car's progress on the road and alerts unconcentrated drivers.

Driver fatigue is a major traffic-safety problem the world over. According to the U.S. NHTSA (National Highway Traffic Safety Administration), drivers who fall asleep at the wheel cause about 100,000 accidents annually in the United States alone, resulting in 1,500 fatalities and more than 70,000 injured drivers and passengers.

The situation is similar in Europe. The German Insurance Association GDV estimates that about 25 percent of all fatal accidents on the German Autobahn are caused by driver fatigue.

Volvo's Driver Alert Control is an important innovation. It is primarily intended for situations where the risk of losing concentration is the greatest and where an accident would have severe consequences. For example a straight, smooth road that lulls the driver into a sense of relaxation and where the risk of distracting activities or falling asleep is higher. The system steps in at 65 km/h and stays active as long as the speed exceeds 60 km/h.


Registers what's happening on the road

Driver Alert Control monitors the car's movements and assesses whether the vehicle is being driven in a controlled or uncontrolled way. This method is unique among vehicle manufacturers and is very reliable.

"We do not monitor human behaviour - which varies from one person to another - but instead the effect that fatigue or decreased concentration has on driving behaviour. Our system is based on the car's progress on the road. It gives a reliable indication if something is likely to go wrong and alerts the driver before it is too late," explains Daniel Levin, project manager for Driver Alert Control at Volvo Cars. He adds:

"We often get questions about why we have chosen this concept instead of monitoring the driver's eyes. The answer is that we don't think that the technology of monitoring the driver's eyes is mature enough yet."

Driver Alert Control can also cover situations where the driver is focusing too much on his/her cell phone or children in the car, thereby not having full control of the vehicle.

"This is a positive side-effect of our concept, and this is possible since the system evaluates driving behaviour rather than human behaviour," says Daniel Levin.


Text messages and audible signals

From a technical viewpoint, Driver Alert Control consists of a camera, a number of sensors and a control unit.

The camera, which is installed between the windscreen and the interior rear-view mirror, continuously measures the distance between the car and the road lane markings. The sensors register the car's movements. The control unit stores the information and calculates whether the driver risks losing control of the vehicle.

If the risk is assessed as high, the driver is alerted via an audible signal. In addition, a text message appears in the car's information display, alerting him or her with a coffee cup symbol to take a break.

What is more, the driver can continuously retrieve driving information from the car's trip computer. The starting-point is five bars. The less consistent the driving, the fewer bars remain.

"It is, of course, always the driver's responsibility to take a break when necessary, but sometimes you might not realise that you're not alert enough to drive. In such situations, Driver Alert Control can help the driver make the right decision, like taking a refreshing break or a nap, before the concentration level becomes too low," Daniel Levin concludes.


Lane Departure Warning (LDW)

On US Highways, single-vehicle road departures account for approximately one fourth of all accidents and one third of all fatalities, statistics that emphasize the risk of losing concentration in smooth driving conditions.

Volvo Cars addresses this by introducing Lane Departure Warning. The system helps prevent single-vehicle road departure accidents as well as head-on collisions due to temporary distraction.

Volvo Cars' researchers estimate that the LDW system can help prevent 30-40 percent of these types of accidents at speeds between 70 and 100 km/h.

LDW is activated via a button on the centre stack and it alerts the driver with a gentle warning sound if the car crosses one of the road markings without an obvious reason such as use of the turn indicator.

The system also uses a camera to monitor the car's position between the road markings. LDW steps in at 65 km/h and stays active as long as the speed exceeds 60 km/h.


System limitations

Some of the described systems' availability depends on the number and quality of visible road markings. The lane markings must be clearly visible for the camera Poor light, fog, snow and extreme weather conditions can make the system unavailable.

2 minute in 35 sekund. A se samo meni zdi nesprejemljivo, da 70ki pade prednje levo kolo stran preden pristane na tleh?Sicer mi je jasno, da naredijo toliko testov, da bi bili prvi na tem področju. Po drugi strani se mi pa zdi škoda teh avtov.....Sam bog ve kaj naredijo z njimi ko so enkrat zbiti...

Ne vem, če tole spada v to rubriko.

Tole sem danes videl na avtonetu: http://www.avto.net/_AVTO/ad.asp?ID=5186439&show=1

Kot je videti, se airbagi niso sprožili. Trk je bil očitno nad točko, kjer so tipala za airbage

Pomoje je bilo tako:
Avto se ni zaletel neposredno čelno, na kar nakazuje tudi skoraj nepoškodovan odbijač in maska. Zaletel pa se je nekje v višini luči, po vsej verjetnosti v zadnji del tovornjaka. Hitrost ni mogla biti velika, saj se take poškodbe naredijo že pri nižji hitrosti naleta, ker v tej višini enostavno ni nekih trdnih karoserijskih delov - havbo, luči, vezno steno in ostale pritikline pa enostavno poreže pri takem naletu. Plus tega, da so vsi ti deli mehki, se je avto tudi manj sunkovito ustavil kot pri trčenju neposredno v sredino spredaj. Pojemek je bil manjši in airbagi so ostali celi.
