Active safety features are those that help to prevent or mitigate road crashes. Unlike passive safety features — which are designed to protect vehicle occupants once a crash has occurred — active safety features will engage to either prevent the crash from occurring, or reduce the severity of an unavoidable crash. There are several ways that active safety features can help prevent crashes.

The big news these days in newer model vehicles is the availability of active safety features. But what exactly is an active safety feature and how is it different from a passive safety feature? Here are some of the differences between the two. A passive safety feature is a system that does not do any work until it is called to action.

Passive safety systems: what are they and how do they work?

Active safety features are those that help to prevent or mitigate road crashes. Unlike passive safety features — which are designed to protect vehicle occupants once a crash has occurred — active safety features will engage to either prevent the crash from occurring, or reduce the severity of an unavoidable crash.

There are several ways that active safety features can help prevent crashes. Some features like forward collision warning systems and lane departure warning systems activate a warning system when potentially dangerous situations are detected. Other active safety features work as failsafe measures to protect against driver errors. For example, brake override engages to deactivate the accelerator pedal in the event that both the gas and the brake pedal are pushed down simultaneously.

What all active safety features have in common is that they constantly monitor one or more aspects of the vehicle for potential hazards. These features work silently in the background, checking the rotation speed of the tires, the location of the vehicle within its lane, or the position of the gas and brake pedals relative to each other.

When something problematic is detected, active safety features act autonomously to correct the situation safely. Active safety features offer an extra layer of protection on the road. While they cannot replace a safe and attentive driver, these features can be relied on to engage when they are most needed.

Active Safety System Vs Passive Safety System – What is the difference?

Advanced Microsystems for Automotive Applications pp Cite as. Passive safety systems have contributed very much in reducing injuries or fatalities related from vehicle accidents for the last decades. A further increase of road traffic safety requires also new generations of sensing systems. The systems shall also be capable to address the area of passive safety and active safety. With this type of sensing systems relevant data is collected in the surrounding of the vehicle. By combining this primary data with additional data from the vehicle, e. The system is also used to support braking functions to reduce the stopping distance of a vehicle.

Active Safety includes set of safety features which reduce the chances of an accident or collision in the first place. Manufacturers employ the active safety systems mainly to avoid the accident. These systems activate before the accident takes place so that they could possibly avoid the accident. This includes characteristics such as road holding, visibility, comfort, handling, and ergonomics. However, the airbags , seatbelts , and others safety features come into play during an accident. Hence, they are called the passive safety systems.

The first, mainly in the United States, refers to automobile safety systems that help avoid accidents, such as good steering and brakes. In this context, passive safety refers to features that help reduce the effects of an accident, such as seat belts , airbags and strong body structures. This use is essentially interchangeable with the terms primary and secondary safety that tend to be used worldwide in standard UK English. However, active safety is increasingly being used to describe systems that use an understanding of the state of the vehicle to both avoid and minimise the effects of a crash. These include braking systems, like brake assist , traction control systems and electronic stability control systems, that interpret signals from various sensors to help the driver control the vehicle. These forward-looking technologies are expected to play an increasing role in collision avoidance and mitigation in the future.


Active Safety Systems as the term suggests play a preventive role in mitigating crashes and accidents by providing advance warning or by providing the driver with additional assistance in steering/controlling the vehicle. are common Passive Safety Systems deployed in vehicles these days.


Active safety features

Passenger safety occupies a prime spot in the automobile sector today. Proactive policy implementation and consumer awareness has played a key role in making automotive safety systems popular. However the penetration of these lifesaving technologies differs from country to country. Economically developed countries tend to have a high penetration of these technologies across various passenger and commercial vehicle segments. Airbags, Seatbelts, Whiplash Protection System etc.

In other words, passive safety technology is all about mitigating the consequences of an accident during and after impact, as from the moment that first contact is made. Airbags are cushions that are inflated extremely quickly upon impact and subsequently deflated to protect passengers during a collision. They provide a soft restraint between the occupants and the vehicle interior during the crash, which can reduce or even prevent injuries.

Sensors for Active and Passive Safety Systems

Ей вспомнились мечты коммандера: черный ход в Цифровую крепость и величайший переворот в разведке, который он должен был вызвать. Она подумала о вирусе в главном банке данных, о его распавшемся браке, вспомнила этот странный кивок головы, которым он ее проводил, и, покачнувшись, ухватилась за перила. Коммандер. Нет. Сьюзан словно окаменела, ничего не понимая.

В голове у Сьюзан беспрестанно крутилась мысль о контактах Танкадо с Хейлом. Кто будет охранять охранников. - подумала. Quis custodiet ipsos custodes. Эти слова буквально преследовали. Она попыталась выбросить их из головы. Мысли ее вернулись к Дэвиду.

Себе Стратмор купил Скайпейджер, который запрограммировал на ту же частоту. Начиная с этого момента его связь с Халохотом стала не только мгновенной, но и абсолютно неотслеживаемой. Первое послание, которое он отправил Халохоту, не оставляло места сомнениям, тем более что они это уже обсуждали: убить Энсея Танкадо и захватить пароль. Стратмор никогда не спрашивал у Халохота, как тот творил свои чудеса: тот просто каким-то образом повторял их снова и. Энсей Танкадо мертв, власти убеждены, что это сердечный приступ, прямо как в учебнике, кроме одного обстоятельства. Халохот ошибся с местом действия.


A passive safety feature is a system that does not do any work until it is called to action. These features become active during an accident, and.

Она казалось напуганной еще сильнее, чем раньше. - Мистер, - сказала она дрожащим голосом, - я не говорила вам, как меня зовут. Откуда вы узнали. ГЛАВА 74 Шестидесятитрехлетний директор Лиланд Фонтейн был настоящий человек-гора с короткой военной стрижкой и жесткими манерами. Когда он бывал раздражен, а это было почти всегда, его черные глаза горели как угли. Он поднялся по служебной лестнице до высшего поста в агентстве потому, что работал не покладая рук, но также и благодаря редкой целеустремленности и заслуженному уважению со стороны своих предшественников.

Он почувствовал жжение в боку, дотронулся до больного места и посмотрел на руку. Между пальцами и на кольце Танкадо была кровь. У него закружилась голова. Увидев выгравированные знаки, Беккер страшно удивился. Он совсем забыл про кольцо на пальце, забыл, для чего приехал в Севилью.

Плеснув водой в глаза, Беккер ощутил, как стягиваются поры. Боль стала утихать, туман перед глазами постепенно таял. Он посмотрелся в зеркало. Вид был такой, будто он не переставая рыдал несколько дней подряд. Беккер вытер лицо рукавом пиджака, и тут его осенило.
