Different Car Safety Features Explained

Driving a car has the potential to be fatal if not done right. Moreover, road accidents happen all the time and some of them are inevitable. In such scenarios, having a car that is loaded with safety features can prove to be a savior. Most buyers prioritise fancy entertainment units and convenience-boosting technologies without realizing how important safety features are. Now, there are many such safety features available in the market. While some are offered as standard with almost every car, some are only available in more expensive cars. Moreover, safety features are categorized into two: active and passive. Active features will intervene before an accident to improve safety while passive ones operate after a crash occurs to protect the passengers. So, let's take a look at all the safety features that are offered in cars to ensure safety of the driver and passengers.              

Active Safety Features:

The purpose of the Tyre Pressure Monitoring System (TPMS) in your vehicle is to warn you that at least one or more tyres are significantly under-inflated, possibly creating unsafe driving conditions. 

Speed-limiters

Many cars fitted with cruise control also come with a feature to prevent the car from being driven above a pre-set speed. Speed-limiting devices can normally be set to any speed and will gently reduce engine power when it is reached. Many systems will deactivate if the driver floors the accelerator, so they can still react to developing situations on the road.

Lane-keeping assistance (LKA) systems monitor the position of the vehicle with respect to the lane boundary and apply torque to the steering wheel, or pressure to the brakes, when a lane departure is about to occur.

ABS with Electronic Brake-force Distribution

Electronic Brakeforce Distribution or EBD is an extension of the Anti-Lock Braking System (ABS). It ensures that the right amount of force is applied to each wheel in order to bring it to a complete halt. Though the Anti-Lock Braking System or ABS ensures that the wheels do not lock under heavy braking, EBD makes sure that each wheel gets the right amount of braking force.

Autonomous Emergency Braking

Autonomous emergency braking (AEB) systems start braking automatically if a collision is imminent and the driver is not taking any action (or is not doing so fast enough). AEB is able to detect a potential collision and activate the braking system to decelerate the vehicle with the purpose of avoiding a collision, or at least mitigating its impact.

Electronic Stability Control

ESC is a computerised technology that improves a vehicle's stability by detecting and reducing loss of traction. In such a scenario, it automatically applies the brakes to help steer the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer.

Passive Safety Features:

Seat-belts

Seatbelts (or safety belts) are restraint systems that keep passengers correctly positioned during an accident or sudden stop, thereby reducing the impact of the vehicle interior on the body and preventing people from being ejected.

ISOFIX, essentially, is a standardised international child seat fitting system. In other words, it is the international standard for attachment points for child safety seats in cars. Car seats differ in design, shape and size. So does the length of a seatbelt as well as seatbelt anchorages. This makes it problematic to fix a child seat correctly and securely. In fact, a number of surveys indicate that child car seats are fitted incorrectly,  making them ineffective in securing a kid in the event of an accident. ISOFIX seats solve this problem by providing an easier and secure way of attaching child seats in a car. It's also different because it removes the need to use the car's seatbelt to secure the child seat.

Driver and Passenger Airbags

The driver-side airbag has been made mandatory under the BNVSAP safety norms in India. But, you should look for a car that at least has dual airbags at the front, for both the driver and passenger. Any number more than that is great. Airbags play a crucial role during accidents as they act as restraints and prevent the driver and passengers from incurring serious injuries.

Pedestrian Airbags

The pedestrian airbag (Pedestrian Airbag) is fitted under the bonnet near the windscreen. In the event of certain frontal collisions with a pedestrian, the sensors in the front bumper react and the airbag inflates if required, based on the force of the impact.
