What is active safety and why is it good?

Active safety refers to technology designed for minimizing the risks of crashes, collisions, and other vehicle accidents. These technologies aim to prevent or mitigate driving accidents and other safety incidents. These safety features constantly monitor the performance and surroundings of a vehicle.

With active safety, drivers will have more control during risky situations. Also known as primary safety features, active safety systems prevent or mitigate an accident before contact is made. With these technologies, drivers are warned of possible incoming hazards. They are automatically triggered when vehicle conditions become high risk.

Another important function of active safety is that it reduces the speed of a vehicle by a few kilometers before impact during unavoidable collisions. As a result, it can reduce the consequences of a collision if it cannot be avoided.

Active vs Passive Safety

Active safety uses cutting-edge road safety technology. They harness emerging technologies allowing drivers to have greater awareness. Some technologies even target the human senses allowing drivers to have greater prescience over the actions of other road users before they happen. Active safety relies on some sophisticated computer equipment to process information connected to external sensors performing safety-sensitive mechanical assistance.

In contrast, passive safety is included in the vehicle to aid passengers during a crash. They are usually installed as part of the car’s design and serve as the last line of defense against serious injuries and crashes. Examples of passive safety are airbags that deploy when the car decelerates beyond braking speed, seat belts that lock into place, crumple zones, and high-strength glass.

Active works with passive safety in tandem to ensure driver and passenger safety, Neither is more important than the other. They are just activated at different times. The bottom line is that road safety will all boil down to you.

Examples of Active Safety

Active safety technology can be broken down into different waves.

First Wave

It is already fitted into most today’s passenger cars and commercial vehicles. Here are some examples of active safety technologies installed in new cars today:

  • Anti-lock braking system (ABS). This safety feature keeps the wheel from locking up during heavy braking allowing the driver to keep steering.
  • Electronic Stability Control (ESC). ESC helps prevent the vehicle from skidding and the driver from losing control while turning a corner. Electronic stability control automatically triggers the brakes to help the vehicle steer in the right direction.

Second Wave

The second wave of active safety measures uses cutting-edge technology like onboard sensors, radar, cameras, GPS, and lasers. This includes the following technologies:

  • Autonomous Emergency Braking (AEB).  This technology automatically activates the brakes if there is an imminent collision and the driver is not taking any action. AEB can detect a potential collision and trigger the brake to avoid it or at least mitigate the impact.
  • Lane Departure Warning (LDW). This safety measure warns the driver when leaving a marked lane without using the indicator or if the vehicle is drifting away from its travel lane.
  • Lane Keeping Assistance (LKA).  This technology adds torque to the steering wheel or pressure to the brakes when the vehicle is about to take a different lane.
  • Drowsiness and Attention Detection. This technology provides an assessment of the driver’s alertness and warns them when they need to take a break. This system monitors how long the driver has been on the road and analyzes steering wheel operation.
  • Speed Limit Information (SLI).  This technology notifies the driver of the current speed limit by displaying it on the dashboard and/or navigation system. Using a camera, it recognizes road signs or analyzes speed-limit data from the navigation system. Most SLIs use a combination of both.
  • Tire Pressure Monitoring Systems (TPMS). TPMS tracks the air pressure of a vehicle’s tire and delivers real-time information to the driver. For example, a low-pressure indicator signifies underinflation.
  • Intelligent Speed Assistance (ISA). This safety measure prevents the driver from going beyond the speed limit through road-sign recognition cameras and GPS-linked speed limit databases.

Other Active Safety Technologies

  • Forward Collision Warning.  Similar to AEB in the sense that it will alert the driver if there is danger ahead. However, a forward collision warning will not automatically apply the brake.
  • Adaptive Cruise Control. This technology allows the driver to set the speed limit. However, as the name suggests, it will adapt to other road users by applying the brakes to mirror surrounding traffic.
  • Blind Spot Monitoring. This is another useful awareness tool. With this technology, the driver will be able to actively monitor the blind spot over the shoulder, notifying the driver of any hazard using a warning light.
  • Rear-cross Traffic Alert.  Backing up can be a challenge for most drivers. With rear-cross traffic alert, drivers can effectively back up on car parks and driveways.

At the end of it all, ensuring road safety is still the responsibility of the driver. You can reduce accidents and protect your family by being alert and decisive when driving.
