Talk:Vehicle rollover

Dynamics

"Such an event can be triggered by a sudden turn to avoid a collision, or a loss of traction due to water or ice."

Oh can it really? In order to roll over as a result of a turn, you generally need a lot of traction (friction between the tyres and the ground is necessary to hold the bottom of vehicle in one place whilst the physics acting against the top 'push' it over). While there may still be sufficient traction on a wet road to accomplish this, I severely doubt there would be on snow or ice, even in a vehicle with a very high centre of gravity.

List of rollover risk

I browsed the NHTSA site for some numbers, mostly for ordinary cars for Joe Public. We might make a list out of them. Any suggestions for other cars? Please add link.

2011 Chevrolet Tahoe 24.6%

2011 Ford F-150 19.8%

2011 Audi Q7 SUV AWD 18.5%

Thanks - next problem is which cars to exclude! By sales numbers? I wanted to make a big graph of Center of gravity height vs. rollover risk, but CoG numbers are even harder to find than NHTSA % . I suggest a table for less than 10%, and a table for most sold cars. TGCP (talk) 15:14, 16 September 2015 (UTC)

More than one list sounds good. Putting a sedan and a SUV/van in the same list may not be so useful. Perhaps also lists for different types of vehicles? If the lists become too long, they could instead be a top-10, i.e. risk for 10 most sold cars and 10 with lowest risk.

Also, I tried to find a definition of this rollover risk, which would make it useful not only in a relative sense. But no luck so far.

Btw, the least ineffective method I managed to use to find the risk was to browse the vehicles per 'Manufacturer'. Simply getting safercar.gov to list the cars after their rollover risk would be better... Lklundin (talk) 16:36, 16 September 2015 (UTC)

Ah, using "Search by Manufacturer" with 100 results per page is MUCH more efficient than what I did: clicking each model and year to find... nothing. Example: BMW, 566 results. Now we can get somewhere. Anybody, please join in. TGCP (talk) 20:36, 16 September 2015 (UTC)

Rollovers have a higher fatality rate than other types of crashes ?

I added the statement that rollovers 'have a higher fatality rate than other types of vehicle crashes', citing safercar.gov (which is run by NHTSA). A different, older and more detailed page from NHTSA says that 'In terms of fatalities per registered vehicle, rollovers are second only to frontal crashes in their level of severity' (Vehicle Dynamic Rollover Propensity). Ideas on how to best deal with this apparent self-contradiction are welcomed. Thanks. Lklundin (talk) 07:43, 17 September 2015 (UTC)

We could deal with this issue considering not only US case, but also European case: because as stated hereunder, "Inside the European union, most rollovers occur off the carriageway. When the occupant is not ejected from the vehicle and the car does not strike any rigid objects, rollovers are the least injurious of the different impact types".

Europe

Within European union, it is considered that HGV rollovers do not usually result in serious injury, making the "rollover stability system" to not increase safety.

Inside the European union, most rollovers occur off the carriageway. When the occupant is not ejected from the vehicle and the car does not strike any rigid objects, rollovers are the least injurious of the different impact types, because deceleration is longer and slower..

Nonetheless, rollover risk depends upon the centre of gravity, suspension characteristics and loads carried. The severity of injury depends on the presence of crash-protective roadsides and the speed of impact..

It is considered that Electronic Stability Programmes can contribute to reduce some accidents including rollovers..

In Sweden one to two rollover accidents occur every day.

UK and Gemany

It looks like for the light vans and minibuses, 22% of those accidents are rollovers in the UK, and 16% in Germany. Source: http://ec.europa.eu/transport/road_safety/sites/roadsafety/files/pdf/ersosynthesis2018-vehiclesafety.pdf

Also, but that is another issues rollovers tend to increase with the ABS, according to the exact same source.

ESC to prevent rollover crashes?

According to United nations the ESC is effective at preventing different types of crashes including rollover crashes.

Icreasing Rollover risk in Europe

It looks like rollover are increasing in Europe:

• "Rollover accidents seem to be a rising problem in Europe" Source: https://bast.opus.hbz-nrw.de/opus45-bast/frontdoor/deliver/index/docId/439/file/Rollover_Scenarios_in_Europe.pdf

According to the same source: Rollovers, as a single event (rollovers without the occurrence of any impact) are rare events in Europe. Also, Sport Utility Vehicles (SUV), Multi Purpose Vehicles (MPV) and other light trucks are over-represented in rollover accidents. — Preceding unsigned comment added by 81.185.253.2 (talk) 20:47, 24 June 2019 (UTC)
