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, roughly half of all drive00 – 1200 words don’t press the brake quickly enough or hard enough to make full use of their vehicle’s braking power (NHTSA 2010; Page et al. 2005). Brake assist is designed 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 auto body shop kingston different names are significant because through all brake assist systems have the same purpose, some are designed differently.

 

When would brake assist be useful?

Brake aid is useful whenever drivers must brake hard to generate an emergency stop. Brake assist usually works in combination with anti-lock braking systems (ABS) to help make braking as successful as possible while preventing 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 car or truck.

-A large creature runs out into the road, forcing you to create an emergency stop.

-Cresting a hill, you encounter an unexpected line-up of automobile safety and you must brake hard to avoid 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’s an emergency and promotes braking power. A number of these systems are adaptable, which means they will 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 with an ECU) are eligible to have electronic brake assist installed.

Older vehicles that don’t have an ECU can have a mechanical brake assist system put in. Mechanical systems also use pre-set thresholds, but these are set automatically. This means they are not adaptable to individual drivers. These systems incorporate a locking mechanism that activates when the valve stroke — auto body repair kingston which is directly related to how far the brake pedal is pushed — moves a critical point. After this threshold is passed, the locking mechanism switches the source of braking power from the brake piston valve to the brake booster, which supplies the braking assistance.

 

How successful is brake assist?

The expected benefits of brake assist are many, especially given the sorts of scenarios that brake assist is intended to address. The Insurance Institute for Highway Safety (IIHS) in the United States has determined that the kinds of crashes pertinent to brake assist are those in which the driver saw a hazard, braked, but did not stop in time. Given that, the IIHS quotes that brake assist is relevant to 417,000 crashes per year in the United States, such as 3,080 fatal crashes.

Other studies also support brake help’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 help engaged during an emergency stop. In addition, researchers from France estimate that brake help would reduce injuries in 11% of all crashes, and reduce the total number of road fatalities by 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 solely on the basis of a driver’s braking commands. If the signals of panic braking are there, brake assist will participate to provide stopping support. However, inappropriate, unclear, or delayed braking actions could lead to brake assist either not activating whatsoever or failing to provide all available support.

The first thing to remember is that brake assist has no method of seeing obstacles ahead: it can’t scan for potential dangers and doesn’t warn drivers of any danger. Therefore, auto body shop victoria drivers must continue to be vigilant by paying careful attention to the street and avoid behavior that could make identifying and reacting to obstacles more difficult, like 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 by which they recognize panic braking are set intentionally high. This is to make sure that brake assist does not participate when it is not needed. However, many drivers are not used to applying the brakes hard enough and fast enough to exceed these thresholds and trigger brake assist (NHTSA 2010). To get the most out of brake assist, drivers must apply the brakes forcefully and decisively whenever they realize an emergency stop is required.

 

How common is brake assist in today’s vehicles?

Brake aid was first introduced in high-end European vehicles in 1996. Since that time, brake aid has become remarkably common in Europe and Australia where it is available as either standard or optional on the vast majority of new vehicles. In North America, brake assist was slower to reach the economy vehicle market. However, is now more commonly available within a safety package, and some manufacturers offer brake assist as a standard feature.
