Talk:Anti-lock braking system

message: Is it true what I've heard? With ABS, drivers can steer out of trouble while braking, they tend to steer to avoid & go right off the road...  TREKphiler hit me ♠  04:36, 1 September 2008 (UTC)
thread_title: Skid control

message: This whole article about anti-lock brakes assumes the reader knows exactly what locking is and what causes it. I have no idea. Therefore I have no idea what it is anti-lock brakes are trying to achieve! 78.105.78.36 (talk) 07:05, 6 August 2009 (UTC)
thread_title:  What is locking? 

message: The line "On a very slippery surface such as sheet ice or gravel, it is possible to lock multiple wheels at once, and this can defeat ABS (which relies on comparing all four wheels, and detecting individual wheels skidding)." is not entirely correct. In many systems there is a speed sensor attached to the speedometer that detects any high-rate drop in the indicated speed, not compatible with the vehicle's known maximum braking performance, which the computer may interpret as a moving-vehicle-with-locked-wheels situation.

replies: text: There are issues with ABS on ice, snow and loose gravel that increase stopping distance.  Unless the road surface is known, and the computer programmed to compensate properly, you will not overcome this.  --THE FOUNDERS INTENT PRAISE 17:13, 23 April 2010 (UTC)
thread_title:  Can ABS be defeated? 

message: One thing that I noticed wasn't discussed is the relationship between ABS and tire life.  On any hard surface, if you were to make a panic stop in a non-ABS car and skid, the locked-up tires can develop flat spots (or even fail completely) where the tire was in contact with the road.  Such is not the case with ABS as the tire is essentially rolling all the time, preventing tire damage.

thread_title:  Suggestion:  ABS and the effect on tires 

message: Without getting into the technical bits and trying to factually pick the article over (honestly, I went to school for that already, never again), why does the last few portions look like copy-pasted junk that someone never proofread? I'd put it together myself but it looks like a safety article that got pasted in with no formatting control, and most of it seems irrelevant for a wikipedia entry.
Furthermore, "especially when the USA government requires all 2008 and later automotive sold in USA must equip CAN bus.[13]" is not entirely accurate. Vehicles between 8,500 and 14,000 US Pounds GVWR may use SAE J1939, which would include most 3/4 ton pickups and upward. Some newer half tons might fit in there too, but I'm not sure.
Maybe it'd be better to just remove all of the junky portion and start over? It's barely readable as it is, let alone wiki-ey..
Addendum #1: And we seem to have pretty much neglected power-boosting, accumulators, and air brake ABS. The first two I really can't see where to point you except OEM system manuals; as for air brake ABS, I believe Bendix published an "Air Brake Manual" that was available in PDF format for a long time. I can't seem to find it anymore, however. 24.59.103.114 (talk) 22:41, 5 July 2010 (UTC)

thread_title:  Article Quality 

message: It seems the term 'car' and 'vehicle' are used interchangeably throughout this article. Although a quick check with the Merriam-Webster On Line dictionary leads me to think that this does not result in the incorrect usage of either word it does seem to me to be of poor style. Furthermore it may seem to come readers that a car is a more specific term than vehicle -- in North America a 'car' strictly speaking would be considered a relatively small passenger vehicle in comparison to a 'truck' which is often marketed as a larger vehicle aimed at transporting construction materials.  —Preceding unsigned comment added by NoCoolNamesRemain (talk • contribs) 03:02, 25 July 2010 (UTC)
thread_title:  Terminology: "car" versus "vehicle" 

message: In the second paragraph of this article someone has written:
"ABS offers improved vehicle control and increases stopping distances on dry and especially slippery surfaces, on loose surfaces like gravel and snow-on-pavement, it can slightly increase braking distance while still improving vehicle control.[1]"
I checked the provided citation and could not find any evidence that anti-lock braking systems can slightly increase braking distances on dry surfaces. All evidence I could find (particularly section 2.4, which refers to track testing of abs systems) suggests that abs systems either slightly decrease or have no effect on stopping distances on dry pavement compared to non-abs systems. The text I quoted is probably just a typo, but we need to double check ourselves and make sure everything we write is factually true. If there are no objections, this sentence should be changed.

thread_title:  How ironic that an article on Anti Lock breaking is locked 

message: The earliest automotive application of anti-lock control of braking that I'm aware of is on Duesenberg automobiles in the late 1920s, though it was a mechanical system and obviously not electronic ABS.  Someone else may have done it before Duesenberg.  Bendix Corporation in the U.S. had some of the earliest patents on electronic anti-lock braking for aircraft landing gear in the 1930s and I believe their system may have been fitted to Douglas aircraft beginning around 1935.  Is there someone out there who is sufficiently well-versed on this topic to clean up this article?  — Preceding unsigned comment added by Arcas2000 (talk • contribs) 05:39, 21 August 2012 (UTC)
thread_title:  This article has a lot of quality issues re early history of anti-lock brakes 

message: In the "effectiveness" section, the Munich study's results and its conclusions are at odds. could someone who knows of the study correct this. Sfahey (talk) 17:17, 30 January 2015 (UTC)
replies: text: There are a number of studies from the early history of ABS that found similar results. A police force from the 1990s had trouble when some of their cars had ABS and some didn't. Officers never knew when they would get a car with ABS. I think my link to that story is in the discussion above. The Berlin cab drivers were not familiar with ABS; it was new in those days.<P>The reason is that ABS is not a passive safety feature. Drivers have to be trained to change how they drive when they have a car with ABS. They have to ignore the strange pedal vibrations when ABS activates. They have to remember that they can steer and brake at the same time. They have to hold the pedal firmly and not try to pump the brakes themselves. Drivers who have been using non-ABS cars for decades can't just change how they drive overnight.<P>This has led to some contradictory beliefs about safety, such as Risk compensation. The overall data show that safety technology has drastically reduced traffic casualties, yet early studies often show the benefits don't appear right away. You could say the same about air bags -- you need to change behavior to get consistent seat belt use, and move kids to the back of the car, before you see the safety benefits.  --Dennis Bratland (talk) 18:12, 30 January 2015 (UTC)

thread_title:  Merger with [[Anti-lock braking system for motorcycles]] 

message: Currently the article says: "Although ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces, on loose gravel or snow-covered surfaces, ABS may significantly increase braking distance." A snow-covered surface is slippery, so that distinction is nonsensical the way it is written here. Also, three references are provided as footnotes, two of them books to which I don't have access and the third one is a pdf file which I have verified and couldn't find any reference to increased breaking distance by searching for the keyword "breaking distance". It occurs only 1 time in the document in a historic context and does not explain this phenomenon or even say that this is a contemporary conclusion (rather than the result of a superseded test for example, with newer tests showing the opposite to be true). Can someone improve this aspect of the article? --boarders paradise (talk) 05:38, 10 December 2018 (UTC)
replies: text: I'm not surprised you couldn't find "Breaking distance". "Braking distance" might be more useful. Anyway, yes it is true, but there's some weird commas being used. I'll rewrite it.Greglocock (talk) 06:47, 10 December 2018 (UTC)
replies: text: A locked wheel might pile up loose gravel and snow in front of it, which stops the car very quickly. That is basically the only case in which locking wheels might help. --Yhdwww (talk) 12:39, 12 January 2020 (UTC)
