What is Brake Assist?
Brake aid is an active vehicle safety feature intended to help drivers come to a stop more quickly through an episode of emergency braking. Studies show that when making emergency stops, about half of all drive00 – 1200 words don’t press the brake quickly enough or hard enough to make complete use of their vehicle’s braking power (NHTSA 2010; Page et al. 2005). Brake assist is intended to recognize the tell-tale signs of emergency braking and provide drivers with extra brake support.
Brake assist is called by other names including Emergency Brake Assist (EBA) and Predictive Brake Assist (PBA). The different names are significant because through all brake assist systems have the same purpose, some are designed differently.
When would brake help be useful?
Brake aid is useful whenever motorists must brake hard to make an emergency stop. Brake assist usually works in conjunction with anti-lock braking systems (ABS) to help make braking as successful as possible while avoiding wheel lockage. There are Lots of relatively common situations that prompt heavy braking:
-A fisherman loses her balance and veers sharply in front of your victoria car paint shop or truck.
-A large animal runs out into the street, forcing you to create an emergency stop.
-Cresting a hill, you encounter an unexpected line-up of automobiles safety and you must brake hard to prevent rear-ending another driver.
How can brake assist work?
According to the National Highway Traffic Safety Administration (NHTSA) in the United States, brake assist systems fall into two general categories: electronic and mechanical. The main difference between the two is in the method used to differentiate panic braking from normal braking.
Electronic brake assist systems use an electronic control unit (ECU) that contrasts cases of braking to pre-set thresholds. If a driver pushes the brake down hard enough and fast enough to surpass this threshold, the ECU will determine that there is an emergency and promotes braking power. A number of these systems are flexible, so they’ll compile information about a driver’s particular braking style and tweak the thresholds to ensure the maximum precision in emergency-situation detection. Modern drive-by-wire vehicles (i.e., vehicles using an ECU) are qualified to have electronic brake assist installed.
Older vehicles that do not have an ECU can have a mechanical brake assist system put in. Mechanical systems also use pre-set thresholds, but these are set mechanically. This means they are not flexible to individual drivers. These systems include a locking mechanism that activates when the valve stroke — which is directly related to how far the brake pedal is pushed — moves a vital point. After this threshold is passed, car body shop victoria the locking mechanism changes the source of braking power from the brake piston valve to the brake booster, which provides the braking assistance.
How successful is brake assist?
The anticipated benefits of brake assist are many, particularly given the sorts of situations that brake assist is designed to address. The Insurance Institute for Highway Safety (IIHS) in the United States has determined that the sorts of crashes relevant to brake assist are those in which the driver saw a hazard, braked, but did not stop in time. Given that, the IIHS estimates that brake assist is pertinent to 417,000 crashes per year in the United States, such as 3,080 fatal crashes.
Other studies also support brake assist’s efficacy for preventing and reducing the severity of certain kinds of vehicle crashes. For example, NHTSA found a reduced stopping distance of around ten feet when brake assist engaged during an emergency stop. In addition, researchers from France estimate that brake assist would reduce injuries in 11% of all crashes, and reduce the whole number of road deaths between 6.5% and 9%.
Does brake assist have any limitations?
Yes. Just like other vehicle safety technologies, getting the most from brake assist requires that motorists understand its purpose and limitations. Both electronic and mechanical brake assist systems activate only on the basis of a driver’s braking controls. If the signs of panic braking are there, brake assist will engage to provide stopping support. However, inappropriate, unclear, or delayed braking actions could lead to brake help either not activating at all or failing to provide all available support.
The first thing to remember is that brake aid has no method of seeing obstacles ahead: it can’t scan for potential dangers and does not warn drivers of any danger. As such, auto body repair victoria drivers must continue to be vigilant by paying careful attention to the road and avoid behavior that could make identifying and responding to obstacles harder, such as speeding, impaired driving, fatigued driving, and distracted driving.
Also, drivers should be aware that the pre-set thresholds in both electronic and mechanical brake-assist systems where they recognize panic braking are set deliberately high. This is to ensure that brake assist does not engage when it’s not needed. However, many drivers are not used to applying the brakes hard enough and fast enough to exceed these thresholds and activate brake assist (NHTSA 2010). To get the most out of brake assist, motorists must apply the brakes forcefully and decisively as soon as they realize an emergency stop is required.
How common is brake assist in today’s vehicles?
Brake assist was first introduced in high-end European vehicles in 1996. Since then, brake assist has become very popular in Europe and Australia where it is available as either standard or optional on the majority of new vehicles. In North America, brake help was slower to get to the economy vehicle marketplace. However, is now more commonly available within a security package, and a few manufacturers offer brake assist as a standard attribute.
