Technology has changed our lives. One cannot deny the fact that everything has become simple and secure these days. We all know that technology provides a lot of comforts, in the case of driving it can be lifesaving. We hear news of some mishap on the road every day. Many accidents occur due to various different reasons. Traffic is increasing on the roads and we see a lot of speeding cars. With more powerful vehicles making their way into the market, there is a dire need for technology that can make driving safe. This is where ADAS enters the frame.

ADAS is an advanced driving technology that aims to make driving much safer. The technology is designed to reduce accidents that occur due to driver error. The Advanced Driving Assistance System alerts the driver in case of any obstacles on the road ahead. Advanced Driving Assistance Systems or ADAS have gained a lot of attention in recent years. It has become an essential part of the vehicle to enhance passenger security.

The ADAS system includes several cameras and sensors which makes sure that the passengers are safe. The Advanced Driver Assistance System (ADAS) uses a couple of systems such as lane departure warnings, forward collision warnings, adaptive cruise control, lane-keeping assistance and blind-spot monitoring to alert the driver. In this blog, we are going to tell you everything you need to know about the forward collision warning along with its working and some real-life examples as well

Forward collision warning 

Forward Collision Warning or FCW is a system that is included in the ADAS. It warns the driver when the car approaches another car or obstructions on the path ahead. The system also aims to reduce rear-end collisions, when an object or vehicle comes suddenly in your path not allowing you enough time to brake.

How does it work?

The Forward collision warning system uses all kinds of new tech like camera, radar and laser technology to watch the road ahead and look for any car or obstruction that can deal some heavy damage on the car.

It automatically alerts the driver so that he has enough time to brake and prevent any damage or a serious accident. The system can provide both visual and audio warnings. Some models even include haptic warnings that have the option for seat or steering wheel vibration. 

Some common terms related to FCW

While the new cars include the FCW technology, not every company has bought common naming for the ADAS systems. Here are some alternative terms used for the Forward Collision Warning system are-

  • Pre-collision warning
  • Front collision warning
  • Forward collision alert
  • Forward obstruction warning
  • FCW with an auto emergency braking system

The FCW offers a lot of facilities including automatic braking for the prevention of forward collision or making the damage lesser than usual. While the FCW alerts the driver while the AEB (automatic emergency braking) takes control to prevent serious damage. When both of the systems are combined then it is also known by the following names:

  • Collision avoidance
  • Auto collision avoidance
  • Forward collision avoidance
  • Forward collision avoid assist
  • Collision mitigation
  • Collision mitigation braking system
  • Frontal collision avoidance system
  • Pre-collision safety system
  • Pre-collision assist
  • Pre-crash System

Here are some real-life examples of FCW –

While the new futuristic cars have this system, you have to spot the right locomotive company for the FCW system. A few examples are mentioned below-

  • Honda Forward Collision Warning (FCW)

Honda offers this safety system in some of their models, as part of their Honda Sensing package.   FCW can detect vehicles directly in front of the vehicle. When two vehicles come closer to each other on the road the system immediately compares the vehicles’ current speeds to determine if a collision may occur.

FCW issues a beeping sound and flashes an amber “Brake” message in the Multi-Information Display to alert the driver so that he or she can apply brakes on time.

  • Mazda’s FOW (forward obstruction warning)

Mazda has named the system similar to the original name, called the Forward Obstruction Warning. Ford offers an FCW system only on few selected models, it includes brake support but it works differently than the automatic brake system.

Forward collision warning sensors

While each OEM has its different systems, most of them have radar sensors near the front grills of the vehicle that allow it to aim and scan ahead, calculate distance and speed, and notify us of the risks. But the sensors don’t work in every condition, it may not work during heavy rain, snowfall, or fog which can interfere with the radar signals. But you don’t have to worry as it is a temporary malfunction or not working of the system.

If you feel there is an issue with your ADAS, or you are looking to install one for that matter, you should visit a reputed shop with super skilled technicians. There are quite a few such shops in Broken Arrow, Owasso, Jenks, Bixby, Sand Springs, Sapulpa, Glenpool, and Coweta. For instance, if you want to install the camera on the windshield you need to go for the best windshield replacement Tulsa technicians.


The need for ADAS calibrations will soar in the next coming years, it is a good device or system as it protects us from any collisions. But you also have to calibrate it, which requires special hands and special equipment, so only experts can do it.

For the smooth functioning of the ADAS system, it is necessary to maintain all the devices frequently. Devices such as cameras and safety sensors should be aligned properly for proper navigation of the obstacles. If these devices are misaligned even slightly it will result in the malfunctioning of the entire system.

Thus, frequent ADAS recalibration is important. In case your vehicle has experienced windshield repair or windshield replacement, then the ADAS recalibration becomes extremely important.
