What Does Aftermarket Forward Collision Warning Systems Do?

Table of Contents

Did you know that 40% of collisions occur due to driver distraction? Studies have found that in most of these accidents, the drivers failed to stop their vehicles. That’s because hitting the brakes at the last second cannot stop the vehicle immediately. Often, drivers can not evaluate a scenario, resulting in a frontal accident.

Detecting the speed and distance of vehicles ahead of you is challenging for humans. That is where an aftermarket forward collision warning system comes in. It can keep you safe from fatal crashes with its precise detection. You can install this system easily in your vehicle, regardless of its model and brand.

What is it, and what does it do? Let’s take a detailed look at this system’s functions!aftermarket-forward-collision-warning

Introduction to Aftermarket Forward Collision Warning

An aftermarket forward collision warning is a driving assistance system. It studies the speed, distance, and movements of vehicles ahead of you. If there’s a chance that you can collide with those vehicles, it notifies you. Simply put, it scans and predicts an impending crash in the forward view of a car.

This driving assistance system uses vibrations, flashing lights, or buzzers to notify you of a potential collision. This alert method can differ depending on your system’s model and build. Generally, people prefer a hybrid option that combines various modes of alarm, like visual and audible.


History and Evolution Of Aftermarket Forward Collision Warning

Forward collision warning is commonly known as FCW and was first introduced in 2000. Mercedes-Benz was the first company to integrate this relatively newer system in their releases. However, its popularity rose with its introduction in the British market in 2008. Today, almost every new model has this feature built-in. Some of the most well-known companies to adopt this technology include:

  • BMW
  • Mazda
  • Tesla
  • Mercedes-Benz
  • Subaru
  • Audi
  • Volkswagen
  • Toyota
  • Volvo
  • Jaguar
  • Ford
  • Porsche

Now that FCW has become popular, companies are innovating it. Modern features, like automated emergency braking, pedestrian detection, image recognition, and GPS sensors, have become common in this assistive system.

Functions Of Aftermarket Forward Collision Warning

If you look at the aftermarket collision avoidance system reviews, they are generally overwhelmingly positive. Why is that? The system’s wide range of functions can help you understand that. So, let’s see what this system does!

1. Auto Activation

An FCW system doesn’t require manual activation. It turns on automatically as your car reaches 10 mph speed. That is more convenient because many drivers can forget to enable it manually. Since the speed range is so minimal, it offers extra safety. As soon as you hit 10 mph, the system will start detection.

That said, you can turn it off if required. Generally, the system comes with a remote control or a central box with a button. Another way is to remove its power supply and deactivate it for long.

2. Vehicle Detection

The detection method can vary in forward collision warning systems. Generally, there are four modes using radar, cameras, and laser (Lidar). The laser mode is generally in built-in models and is more expensive. Secondly, a camera system requires you to keep track via a screen.

The most effective method is with radar-based sensors. They emit millimeter radar waves to detect a moving or stopped object. The best part is that this system works in all weather conditions, including rain, snow, etc. Alternatively, cameras and laser detection modes might not work in extreme outdoor conditions.

3. Speed & Distance Detection

The sensors in a forward collision warning do the heavy lifting. After detecting a vehicle ahead of you, the sensors calculate its speed and distance. They also measure the distance between you and the other car.

If the vehicle ahead of you is stopping or slowing down, you will get an alert from the system. That’s because that is the most critical situation on the road. When you are driving at high speed, and the car in front of you stops, fatal collisions occur.

4. Alerting the Driver

An FCW system calculates with utmost precision to predict a collision. If it does, it will notify the driver via alerts. It can be seat vibrations, LED lights, beeps, or all these methods.

Choosing a system that doesn’t overwhelm you in critical scenarios is highly recommended. Plus, test it before heading to a busy road. Remember that the forward collision warning light on means a potential crash.

5. Automated Emergency Braking

While every aftermarket forward collision warning doesn’t have automated emergency braking, it is becoming increasingly popular. Today, most built-in and after-sale systems have this feature. Commonly known as AEB, this function jumps in when the situation becomes extremely dangerous.

AEB stops your vehicle immediately to avoid frontal collisions. This function can reduce the chances of accidents and minimize the impacts of a crash.

6. Other Functions

An FCW system is not limited to its basic functions. Modern editions also include robust features, like pedestrian detection. This way, the sensors can detect walking people ahead of your vehicle.

Similarly, other functions include image recognition available in camera-based FCW systems.

Differences Between Factory-Installed and Aftermarket Forward Collision Warning

Many drivers, especially inexperienced ones, don’t know the differences between a factory-installed and aftermarket forward collision warning. Let’s look at the differentiating factors.

1. Installation & Maintenance

Since a factory-installed system comes built-in in a car, it doesn’t require installation. That said, it may need maintenance as frequently as an aftermarket one. But its care can be more challenging. If you need any repairs, you will have to consult your vehicle’s company. Similarly, you will not find spare parts for a factory-installed edition.

That is where an aftermarket forward collision warning has an edge. Even though it may require installation, it is pretty straightforward. Plus, its maintenance can be simple without needing professional assistance. Its repair is also less expensive as spare parts are more accessible.

2. Advanced Features

A factory-installed FCW system will lack flexibility. Thus, you might not find many advanced features in these systems.

An aftermarket edition, however, is more flexible. Modern systems have advanced functions, like AEB and pedestrian warning. These features can make driving stress-free and safer.

3. Detection Accuracy

One thing where a factory-installed FCW excels is in detection accuracy. It is comparatively more precise than an aftermarket variation. That’s because giant car companies design it with a larger budget.

On the other hand, aftermarket systems are generally manufactured by independent companies. They have fewer resources, making their systems less accurate, although not considerably.

4. Manufacturer Companies

Usually, car companies have their own team to design factory-installed FCW systems. That is why these are tailored-fit to suit its specific model’s requirements. However, these brands also offer assistive driving systems individually, like aftermarket forward collision warning Toyota.

At the same time, many independent manufacturers also design built-in systems for these giant companies. The prime example is OYI Electronic, which manufactures factory-installed and aftermarket systems for cars with a success rate of 98%.

5. Remove or Upgrade

Removing a factory-installed FCW system is nearly impossible. You can contact the company, and they might turn it off temporarily. However, you have zero options to upgrade it.

In contrast, an aftermarket FCW can be easily installed and removed. You can upgrade it with a newer model by contacting a professional.

Applications Of Aftermarket Forward Collision Warning

The best aftermarket collision warning system has more versatility. It can be used for personal and professional purposes. The premise of this device is to offer protection to the driver, their vehicle, and others on the road. And this assistive system excels in this purpose.

However, did you know that it is not limited to only cars? Here are other vehicles that can use aftermarket collision warning systems:

  • Buses
  • Commercial vehicles (Trucks, Semi-trucks, Cargo trucks, etc.)
  • Emergency vehicles
  • Vans
  • SUVs
  • Motorcycles

Generally, the aftermarket edition comes in a universal model. That means an FCW system for trucks is eligible for all trucks, regardless of their company and models. This function increases the system’s accessibility.

Moreover, it also suits professional drivers and fleet managers. It helps deliver cargo to the required location with utmost protection while choosing the optimal routes.

Another thing to know is that this system can pair well with other driving assistance tools. For instance, a dash cam with a collision warning is a prime example. It offers a clear view of the road while also preventing rear-end collisions.
