Understanding Safety Features

Understanding Safety Features.

Vehicle safety features have come a long way over the years. Features such as crumple zones, seat belts and airbags all provide protection if you have a crash, but the future of vehicle safety lies with active safety features - safety assist technologies which can prevent a crash from occurring.

The combination of a sound structure, good restraint systems and active safety technologies provide the best chance of survival in a crash.

The safety of a car is based on three key areas:

Structural Integrity - how the shell of a vehicle withstands and channels crash forces away from occupants. This varies substantially from make to make, and model to model. A sound structure is vital when it comes to saving lives.

Safety Features - built-in safety features such as airbags, antilock braking systems (ABS), electronic stability control (ESC) and seat belt pre-tensioners help prevent or manage the forces of impact. All are critical features.

Safety Assist Technologies (SAT) - advanced safety assist technologies assist the driver in avoiding or reducing the severity of a crash. These include autonomous emergency braking (AEB), lane departure warning (LDW), blind spot monitoring (BSM) and fatigue monitoring systems (FMS).

A sound structure is vital when it comes to saving lives.

In a vehicle with sound structural integrity, most of the crash energy is absorbed and dissipated through the vehicle itself, rather than its occupants. The passenger compartment will also keep its shape.

The steering column, dash, roof pillars, pedals and floor panels will not move excessively, where they are more likely to injure the occupants. Doors will remain closed during the crash and will be able to be opened after the crash to assist quick rescue.

ESC and ABS are complementary technologies, working in synchronisation
to provide greater control of the vehicle and reduce the chance of crashing.

What is ESC?

Electronic Stability Control (ESC) has many different names depending on the make of the vehicle, but they all operate in the same manner.

ESC may also be referred to as Electronic Stability Program (ESP), Dynamic Stability Control (DSC), Active Stability Control (ASC) or Vehicle Stability Control (VSC).

How does ESC work?

Imagine the sudden appearance of an obstacle on the freeway. A driver's natural reaction is to quickly steer away to avoid colliding with the obstacle.

This sudden movement can lead to the vehicle swerving sharply one way and then sharply back the other way causing the vehicle to slide, skid uncontrollably or perhaps even roll, often resulting in a serious crash. ESC helps avoid this situation.

By constantly monitoring the position and direction of the car with where the driver is steering, ESC can detect that the vehicle is not travelling in the direction intended.

The system intervenes, instantly manipulating the delivery of engine power and controlling the brake pressure applied to each individual wheel. By taking over, ESC helps to return the vehicle to a straighter and safer line. ESC also assists in controlling a vehicle on unexpectedly tight corners, or on a slippery section of the road. Research shows significant reductions in run-off-road crashes when ESC is fitted.

ESC is particularly beneficial in large vehicles which have a higher centre of gravity, such as SUVs.

What is ABS?

Antilock Braking Systems (ABS) prevent the wheels of a vehicle locking as brake pedal pressure is applied - often suddenly in an emergency or short stopping distance.

This enables the driver to retain steering control, preventing skidding and loss of traction.

ABS is particularly useful on loose surfaces or in wet conditions.

ANCAP Saftey Feature - Airbags

airbags

ANCAP Saftey Feature - Seatbelts

seatbelts

When deployed in a crash, airbags significantly reduce the chance of death or serious injury.
Consumers should look for front, side, curtain and knee airbags for maximum safety.

Frontal Airbags

Frontal airbags deploy on impact in frontal collisions (such as head-on crashes) where the force of impact is great enough that the seat belts alone may not offer sufficient protection. The airbag allows for the driver or front passenger to move forward in a more controlled manner as the vehicle rapidly reduces speed during a crash. Frontal airbags typically deflate quickly after the impact.

Side Airbags

Side airbags deploy on impact in side impact crashes such as at intersections or when a vehicle veers off the road and crashes side-on into an object like a pole or tree. Side airbags can protect both the head and chest of occupants. Usually the chest-protecting airbag is built into the side of the seat and head protection is provided by an inflatable curtain that drops from the roof lining. These airbags may also offer protection in rollover crashes or when two vehicles collide at an angle.

Curtain Airbags

Curtain airbags provide additional safety for the head of passengers seated in the front or rear. They are particularly effective against collision with narrow objects such as poles and trees. Unlike frontal airbags, curtain airbags remain inflated after impact reducing the risk of an unbelted occupant being thrown from the vehicle in a rollover crash.

Knee Airbags

Knee airbags are designed to prevent serious injury arising from an impact with the dashboard or steering column.

All occupants should wear retractable three-point sash style seat belts with pre-tensioner technology that helps prevent or manage the forces of impact during a crash. Lap only belts are less safe.

Audible seat belt reminders are valuable devices that encourage all occupants to wear their seat belts. In nearly 20% of all fatalities on Australian roads, no seat belt was being worn.

Child restraints should be properly fitted and conform to Australian Standards, including anchor points (top tether). For more information, visit
