Is the Antilock Brake System Really Effective in Avoiding Vehicle Crashes? by Bernadette Dalao May 10, 2008 The antilock brake system (ABS) was introduced by car manufacturers in the 1980s. Immediately, it was hailed as a major safety feature because of its ability to help drivers avoid crashes that result from skidding on wet roads. Today, the brakes are standard equipment on most new vehicles - but at a cost of over $1,000. Which leads you to ask if you are getting your money's worth. Maybe not. Antilock brakes are activated when the system senses that one or more wheels are about to lock up - usually, as you apply firm and continuous pressure to the brake pedal. If your car has ABS, you should not pump your brakes when stopping suddenly. Pumping antilock brakes is a dangerous proposition because it deactivates the very technology you want to engage. Unlike regular braking systems, antilock brakes will not lock up the wheels or cause the car to skid out of control when you slam on them. That's because the system reduces brake pressure and pumps the brakes automatically (up to 15 times a second) until the wheels rotate correctly. This maximizes road grip, prevents skidding, enables you to steer while braking, and may allow you to stop more quickly. But do antilock brakes really reduce crashes? Although antilock brakes continue to work very effectively on the test track, they've produced mixed results on the road. U.S. government and insurance-industry studies found that they don't significantly reduce crashes. Even more alarming are two surveys that concluded that cars with ABS are more likely to be involved in fatal single-vehicle crashes. Auto-industry studies, on the other hand, showed that ABS reduced accidents on wet roads by up to 19 percent - and that they prevented nonfatal crashes but not fatal ones. The bottom line is: ABS makes little difference on dry roads and will actually lengthen stopping distances on gravel or soft snow. It is, however, effective in wet conditions. One final caution: Despite their safety benefits, experts say that antilock brakes don't enable you to drive more aggressively or negotiate curves faster. Nor do they shorten the recommended distance you should maintain between your car and the one in front of you.

Killer ABS By Frank Williams The National Highway Traffic Safety Administration (NHTSA) has a mission: “Save lives, prevent injuries, reduce vehicle-related crashes.” NHTSA also commits itself to “providing the most accurate and complete information available to its customers, the American traveling public.” While NHTSA’s progress towards its stated goals is (and always will be) a matter of debate, the agency has failed us. They’ve failed to tell the truth about ABS. Modern ABS consists of a computer (CPU), four speed sensors (one on each wheel) and hydraulic valves (attached to the brake circuit). When the CPU senses that one or more of the wheels are turning significantly more slowly than the others, it decreases the pressure on the braking circuit. If the wheel or wheels then turn too fast (freed from braking), the force is reapplied, creating a pulsing sensation through the brake pedal. When Bosch’s Antiblockiersystem appeared on the US automotive scene in the late ‘70’s, safety advocates hailed electronically assisted braking as a life-saving technology that would reduce the number and severity of accidents. Tests under controlled conditions seemed to support the contention. NHTSA and the insurance industry quickly embraced and promoted the technology. Thanks (in part) to insurance industry discounts, almost every passenger vehicle now sold in America is fitted with ABS. NHTSA’s web site proclaims “…an antilock brake system (ABS) is a safe and effective braking system. ABS allows the driver to maintain directional stability, control over steering, and in some situations, to reduce stopping distances during emergency braking situation, particularly on wet and slippery road surfaces.” The real-world evidence doesn’t support their claims. Researchers have compared accident and fatality rates for vehicles with and without ABS. Other studies have examined the driving records of ABS and non-ABS equipped taxi drivers in Munich and Oslo. The accident and fatality data shows that ABS exacerbates the severity of accidents in certain situations. The taxi study proved that drivers tend to take greater risks in cars equipped with ABS (although the difference in collision rates was not significant). In short, ABS may do more harm than good. More specifically, the studies show that ABS has no real-world effect on dry-surface braking, ABS-equipped vehicles take longer to stop on ice than non-ABS vehicles, ABS-equipped vehicles are more prone to roll-over accidents than non-ABS vehicles, ABS-equipped vehicles are involved more often in single car fatal accidents than non-ABS vehicles, and drivers of ABS-equipped vehicles tend to drive faster and apply their brakes later than non-ABS drivers. The AAA Foundation for Traffic safety has determined that improper driver steering in an ABS-equipped vehicle can send it veering out of control. In their tests, jerking the wheel (as if trying to steer around an obstacle) in a 35 mph panic stop sent ABS-equipped cars careening across two lane widths. (Without the ABS, the car skidded in a straight line.) This behavior may account for the higher roll-over rates for ABS-equipped vehicles. Other research revealed that many drivers don’t use ABS properly; they pump the pedal as they would regular brakes. NHTSA, the insurance industry, manufacturers and engineers are all well aware of ABS’ shortcomings. In 1994, Dr. Charles J. Kahane published a paper for NHTSA entitled “Preliminary Evaluation of the Effectiveness of Antilock Brake Systems for Passenger Cars." Kahane reported that “All types of run-off-road crashes – rollovers, side impacts with fixed objects and frontal impacts with fixed objects – increased significantly with ABS. Nonfatal run-off-road crashes increased by an estimated 19 percent, and fatal crashes by 28 percent.” Kahane also concluded that “Rollovers and side impacts with fixed objects… had the highest increases with ABS. Nonfatal crashes increased by 28 percent, and fatal crashes by 40 percent.” In 1996, the Insurance Institute for Highway Safety published a news release titled “Antilock Brakes Don’t Reduce Fatal Crashes; People in Cars With Antilocks at Greater Risks” In 1998, Leonard Evans of General Motors’ Global R&D Operations checked NHTSA’s ABS crash data and concluded “it is unlikely that on dry roads ABS can materially reduce risk” and, more shockingly, “ABS is associated with a 44% increase in rollover risk.” In 1999, the Society of Automotive Engineers reported that “ABS was found to be associated with a 51 percent increase in fatal rollover crashes on dry roads. For fatal side impact crashes, ABS produced a 69 percent increase for unfavorable road conditions, and a 61 percent increase for favorable road conditions.” The average cost of an ABS system is $240. Multiply that figure by millions of vehicles, add the number of lives lost and the injuries suffered because of ABS' ill effects, and the true cost of this potentially lethal braking systems is evident. At the very least, NHSTA should launch an immediate investigation into the advisability of fitting SUV’s with ABS. Meanwhile, you’ve been warned: ABS can kill.

Stavi za zimu kocnice s Tica

:drink: sta se cudim? :doh: pa to od pocetka tvrdim

Jucer navecer je cesta bila posebno ljigava iako nije bilo snijega pa sam se jos jednom uvjerio kako ljetne gume i abs rade sranje i to moze svako sam isprobat kad opet bude ljigavo i uvjerit se. Manijakalno gazenje na kocnicu rezultira paljenjem abs-a i auto ide i ide i ide..... Dozirano gazenje na kocnicu i auto stane cuda li cuda...

:thumbsup: usput google "Time dilation"

Da ako se govori o vremenu no ja govorim o relaciji vremena, brzine i stacionarnog objekta evo jos jedan primjer Imam marker za paintball koji ispaljuje jednu kuglicu u sekundi, Gadjam te sa tocke A koja je 50 metara od tebe i oboje stojimo na mjestu 0 km/h Kuglice ce te pogadjati u intervalu od jedne sekunde. E sad zamislimo da prolazim pored tebe autom brzinom od 100 km/h Marker i dalje puca jednom u sekundi, ali tebe kuglice pogadjaju u razlicitim intervalima kako se mijenja moja udaljenost. Dok se udaljenost izmedju nas smanjuje interval bi i dalje trebao biti 1 sekunda, ali kako se udaljavam vrijeme potrebno da te svaka kuglica pogodi ce rasti i nece vise biti 1 sekunda iako moj marker i dalje puca 1 kuglicu svake sekunde. Dakle moja sekunda pri 100 km/h za tebe vise nece biti ista kao i kod 0 km/h isto kao sto ni za puza i njegovu djecu nece bit ista u odnosu na mrG-a koji ih je zgazio jer je vozio 300 km/h i gospodina gandalfa bijelog koji je kulturno jahao 40 km/h. 1 sekunda u jednom slucaju = smrt u drugom slucaju = zivot, smrt nije jednako zivot

objasni to puzu

bijeli je sportska verzija, dok sivi ima tc, abs, esp, asr, gsm, pms, sars itd

ionako si sam napisao da pri razlicitim brzinama jedna sekunda nije isto, ali evo da ja dam svoje vidjenje situacije - vozi se mr G u dajwoo lanosu 300 km/h po nekoj prometnici - dolazi do zavoja od 90 stupnjeva (na rubu kojeg je zgrada od 100 katova bez podruma tako da ne vidi iza zavoja) te ga prolazi bez usporavanja naravno jer auto lezi ko trol od 100 tona - po izlasku iz zavoja i dalje pri brzini od 300 km/h zazmiri na 1 sekundu - dok je zmirio maleti na puza golaca sa dvoje djece koji je prelazio cestu na propisno oznacenom pjesackom prijelazu 83 metra od zavoja - koci i zaustavlja se nakon jedan metar unatoc sluzi puzeva koji se cijede sa nejgovih vrelih guma (zahvaljujuci abs-u, trkacim zlajfama i nadprosijecnim refleksima) - nedugo potom gandalf bijeli jasi na svom poniju istom prometnicom galopom od 40 km/h - dolazi do istog zavoja naginje se i prolazi ga bez gubitka brzine - po izlasku iz zavoja zazmiri na 1 sekundu i masta o grupnjaku sa sumskim vilama - kad otvori oci ugleda na 72 metara ispred sebe (11 je prosao zmirecki za onu jednu sekundu) zebru i metar dalje daewoo lanos - u slijedecih nekoliko sekundi cese jaja povlaci uzde, podbada ponija i uz gromoglasan hihot preskace zapreku na cesti galopirajuci u suton

steta da nemaju da si metnu abs i usparaju

1 sekunda pri 300 kmh i 1 sekunda pri 40 kmh nije isto jer govorimo o voznji i situacijama na koje treba reagirat Tema je voznja s ljetnim gumama uz ukljucen ili iskljucen abs. Cinjenica je da ces ovisno o vlastitim sposobnostima dalje stic bez abs-a Kriticna situacija je irelevantna jer pocinje cim prvi put trebas usporit i toga si svjestan pa mozes razmisljat o grabi i 30 sekundi unaprijed ako zelis.

Tu se brka vrlo razlicite situacije voznje, iznenadna opasnost na cesti pri normalnoj brzini i naglo kocenje koje nisi ocekivao i voznja po snijegu kad bi trebao znat da nemozes stat u svakom trenutku. Relevantnost poredbe 1 sekunde pri 300 na sat na pisti i 1 sekunde pri 40 na sat u ilici necu komentirat.

abs je za vozace koji u kriznim situacijama nagaze po kocnici i mole se bogu na snijegu nema ni potrebe za ludjackim kocenjem u krizoj situaciji nego do izrazaja dolazi osjetljivost abs-a na proklizavanje, a ta osjetljivost je uvijek losija nego osjetljivost noge dobrog vozaca i ovi komentari tipa bez abs-a ides ravno s abs-om skreces su komentari one prve skupine jer nema nikakvog razloga ic ravno bez abs-a ako se pravilno i s osjecajem dozira kocnica jel na wrc-u dok se drapaju po finskoj idu svi ravno? niko nema abs... tako da odgovor za 1.000.000 kn glasi, da je bolje bez abs-a (ako znas vozit)

cuje se i na bmw-u

strucni naziv hu hu sova

kolko para tolko muzike mario, ne vozis daewoo

Kod nas se nemoze ni dobit vulkanizera na telefon, nek neko proba nazvat Vulkal ili Aauto Hrvatsku. Onda odes tamo i trazis gume, a ovi se cude ko pura dreku i tvrde da to ne postoji :-)

takve stete bi trebala rjesavat osiguravajuca kuca a ne neki tamo ljudi iz antunovica, imao sam stetu na omv-praonici i njihovo osiguranje mi napravilo procjenu i platilo stetu

Neznam sta opce stavljaju po internetu kontakt mailove. Jebada kad u pol tih firmi nema nekog pismenog da napise dvije suvisle recenice na upit. A danas je fancy imat stranice na internetu i mailove i ta cudesa.

Mene isto zanima cijena za staklo 5x2 metra

Moze neke slike kako to na kuci izgleda
