Active vs. Passive Safety – What You Need to Know

Safety in the car is a topic that certainly interests every driver. Modern cars are designed to maximally protect the occupants of the vehicle - not only by preventing traffic accidents, but also by minimizing the consequences of the collision that has occurred. In this context, we are talking about two basic types of safety features: active and passive safety. Both of these approaches are of great importance and together contribute to reducing the consequences of traffic incidents and protecting the driver and passengers.

What is active security?

Active security Refers to all systems and technologies that help to prevention of accidents. Their goal is to maintain control of the vehicle and avoid dangerous situations in real time.

Examples of active systems include:

ABS (anti-lock braking system) - prevents the wheels from locking during braking.
EBD (electronic brakeforce distribution) - electronic brake force distribution.
ESP (electronic stability program) - a system of stabilization of the driving track.
Traction control systems (ASR) - They prevent the wheels from slipping.
Active cruise control - maintains a safe distance from the preceding vehicle.
Traffic sign and lane recognition systems.

All of these elements are designed to help the driver maintaining traffic safety, often intervening automatically In critical situations.

What is passive security?

Passive security focuses on reduce the consequences of the collision or accident that occurred. Its purpose is to protect passengers in the event of a crash through the design of the vehicle and internal components.

Among the basic passive safety elements they belong:

Seat belts (including three-point belts)-protect the passenger's body, limiting its movement during an accident.
Airbags - They protect the head and chest in a crash.
Air curtains - provide additional lateral protection.
Car seats - Designed for children, adjusted for weight and height.
Safety cage - A rigid vehicle structure that protects passengers.
Controlled crush zone - Body sections designed to absorb impact energy.
Glued glass - Prevent the glass from shattering into sharp fragments.

Passive safety systems not prevent accidents, but have major for reducing its effects.

The difference between active and passive security

Bottom line, active security works before the accident, helping to avoid collisions, while passive safety protects passengers in the event of a collision. Both of these systems are complementary and are integral part of designing modern cars.

Modern cars and a comprehensive approach to safety

Today's vehicles are equipped with both advanced systems active, What passive security systems. Their interaction allows not only to reduce the number of traffic accidents, but also to reduce the consequences of the collision that occurred.

For example:

Dashboard in modern cars has been designed so that in the event of an impact posed no threat For passengers.
Car design includes numerous zones crush and reinforced steel profiles.
Warning systems about an approaching vehicle in dead field They warn the driver of potential danger.
Sensors and radars They monitor the vehicle's surroundings in real time.

What is the importance of proper vehicle design?

Car design is critical to the operation of both active and passive safety systems. Car manufacturers are designing bodies so that during a collision impact energy was absorbed as best as possible by the controlled crush zones, thus protecting the occupants of the vehicle.

Reinforced A and B pillars, appropriately positioned cushions air, as well as optimally arranged upholstery elements - all issues that support the passive safety systems.

Safety seats and seat belts

Do not forget about the basic protection measures, which are seat belts and car seats. Even the most advanced system can not replace well fastened belt Whether properly mounted seat.

Three-point seat belts in conjunction with tensioners pyrotechnics are crucial in moment accident. Child safety seats, in turn, should comply with the current standards and matched with age and height of the child.

The future of automotive safety

Modern trends point to even greater involvement artificial intelligence and systems autonomous In providing security. Cars learn driving style drivers, anticipate the behavior of other traffic participants, and if necessary automatically intervene.

The manufacturers' plans include:

predictive braking systems,
monitoring the driver's health,
fully autonomous vehicles,
Seats that change position before a crash, to minimize its effects.

Security systems - do they have any drawbacks?

Both active as well as passive security forms the foundation of passenger protection. These systems not only help prevention of accidents, but in in case of an accident They protect the lives and health of passengers. However, keep in mind that even the best safety systems are not free from defects. Their operation is based on sensors, cameras and algorithms, which do not always interpret the situation correctly. This can lead to false readings, such as. recognition of a non-existent road sign Whether misjudgment The situation on the road.

It is often the case that systems intervene unnecessarily - braking sharply, warning of an alleged threat or limiting the possibility of maneuvering. In addition, software bugs or temporary loss of signal from sensors can disrupt the operation of the entire system. In such cases driver may feel more frustrated than safe.
