Truck Radar Systems: Explanation and Working

Table of Contents

The Advanced Driving Assistance Systems (ADAS) market has skyrocketed in recent years. That’s mainly because of the industry’s versatility. You can find these systems for almost every vehicle, including trucks, buses, cars, SUVs, motorcycles, etc. However, a truck needs advanced assistance more than other vehicles. They are heavier and bigger, making them more dangerous in accidents.

That is why truck radar systems have become increasingly common. If you are new to this term, let’s uncover everything in this detailed guide!


Introduction to Truck Radar Systems

On the surface, a truck radar system is an advanced driving assistance tool. It helps you prevent truck accidents that would otherwise have devastating results. Generally, it is an upgrade to the traditional truck camera system. Why is that? Let’s see.


Framework of Truck Radar Systems

As the name suggests, this system uses radar waves. It comprises one or multiple sensors mounted at the truck’s front or rear. These sensors emit radar waves to detect nearby vehicles and pedestrians. As a result, the driver gets an alert of that potential threat.

These sensors are more robust than a truck camera recording system. That’s because they are weather-resistant and provide accurate results in every condition. Whether it is raining, snowing, or fog, sensors can easily detect vehicles and moving objects in their proximity.

However, every system uses different sensors. Hence, the detection range can vary with models. Usually, a vehicle in the adjacent lanes or at the immediate rear is detectable by truck sensors.

How Does the Radar System Alert the Driver?

The alert mechanism can also differ depending on the system. Typically, the most common options are visual or audible alerts. You get a separate component that sits on the truck’s dashboard. It gives you notifications if the sensors detect a potential threat.

A visual alert refers to flashing lights. Systems that use this mechanism have LED lights to notify the driver. Alternatively, an audible alert means beeps or chimes for alarm.

Lately, hybrid alert systems have become increasingly popular. They combine both visual and audible notifications for better results. So, the driver is guaranteed to have better retention.

How to Respond to the Alert?

So, let’s say that you are seeing the alert visually, audibly, or both. Your first step should be to assessing the situation. The alert system will provide insights about the location of a potential threat.

For example, a pedestrian walks behind your truck while you are reversing. Thus, you will see a notification from the rear sensors. You should immediately hit the brakes to ensure the pedestrian’s safety.

Similarly, let’s replace the pedestrian with another vehicle. What if a car is driving immediately behind your truck? It wouldn’t show up in the side-view mirrors. However, the sensors will detect it. Once you get the notification, you will become aware of its presence. Now, you can make the right decision when driving straight, changing lanes, or turning.

What Type Of Truck Radar Systems Can You Buy?

The term ‘truck radar systems’ is broad. It packs various advanced assistance tools in an umbrella.


So, how many types of radar are there? Let’s look at all of them to provide a clearer picture:

1. Forward Collision Warning

One of the most common ADAS is Forward Collision Warning (FCW). As the name suggests, it protects you from frontal crashes. It consists of a single camera mounted on the truck’s front bumper.

The sensor detects vehicles and pedestrians in the truck’s frontal view. Then, it uses an intelligent algorithm to calculate the object’s speed, distance, and chances of collision. Lastly, it triggers an alert to notify the driver. The driver can make an informed decision and prevent the forward collision.

2. Collision Avoidance System

The Collision Avoidance System (CAS) has a similar framework as a Forward Collision Warning. However, it utilizes more sensors at the front and rear ends of the truck. Thus, it can detect vehicles on both sides.

A collision avoidance system also works with an alert system. It could be visual, audible, or both. Also, its sensors work in collaboration to monitor front and rear areas.

3. Blind Spot Monitoring System

Commonly known as BSM, it is the most effective advanced driving assistance system. Blind spot sensors monitor the areas that are invisible to the side-view mirrors. These spots are also known as the danger zones, and reasonably so. Many reported truck accidents occur in these areas.

A truck has the most dangerous blind spots among all vehicles. That’s because all four sides are no-zones in different scenarios. The blind spot monitoring system uses sensors to detect vehicles in these areas. It provides real-time updates via alerts about your surroundings. This way, you can make the right decisions and prevent devastating crashes.

Features Of Truck Radar Systems

While you have many types of truck radar systems, some features are common in all of them. Let’s look at them in detail:


1. Sensor-Based Detection

Radar-based solutions use sensors, unlike a truck camera recording system. That is why it has an alert system for output instead of a display screen. These sensors are accurate and provide real-time updates of your surroundings. Also, you don’t have to look constantly at the screen. A sensor-based system doesn’t divide your attention on the road, providing extra safety.

2. Intelligent Algorithm

These sensors use intelligent algorithms to perform their functions. These algorithms help the system calculate a vehicle’s speed and distance. Based on that, it summarizes a potential threat. If the truck can collide, the driver gets an alert. Otherwise, they can continue their movement without any worries.

3. Waterproof & Shockproof

Almost every system uses waterproof sensors. That makes a truck radar resistant to outdoor and weather conditions. So, you don’t have to worry about rain or dirt affecting the sensor’s accuracy.

Similarly, these radar-based systems have shockproof sensors. That means bumpy roads and uneven surfaces wouldn’t affect the sensor’s position.

4. Minimal Human Input

These radar systems focus on automation, requiring minimal human effort. Everything from vehicle detection to user alerts is handled automatically by the system. The only thing a driver should consider is to tackle dangerous scenarios after getting alerts.

Benefits Of Truck Radar Systems

Are you still unsure whether to buy truck radar systems? Then, let us tell you some of their key benefits:


1. Ease Your Burden

A driver doesn’t require experience handling advanced driving assistant devices to use a radar-based system. It automates most of its tasks, eliminating the burden off your shoulders. For example, you don’t have to worry about looking at your blind spots constantly. The sensors can do that for you and provide accurate results.

2. Safer than Ever

Remember that a truck is more dangerous than an ordinary car. Truck crashes affect the driver and others on the road. That is why this solution provides added safety. So you can keep yourself, your truck, and others safe.

3. Easy Installation

Most of these truck radar systems have a straightforward installation method. The sensors are mounted on the front and rear bumpers. You can place the alert system on your dashboard. Connect all the cables, and you are all set!

Even better, the modern market is full of wireless systems. That means you can also eliminate the stress of cables and extensions.

4. Minimal Maintenance

Since the sensors are weather-resistant, they don’t need frequent care. They are also unaffected by dirt, debris, or other unwanted particles. Hence, you only have to clean them after months. Alternatively, many systems, like a truck DVR camera system, may require frequent maintenance,

5. Improved Driving Skills

Beginner truck drivers face many challenges on the road. They may find this large vehicle hard to drive, especially in today’s crowded highways. A radar system makes driving more accessible and manageable. It takes care of some difficult tasks and makes you a better driver.

Many studies and expert opinions have concluded that using an ADAS improves a driver’s response time and decision-making ability.

5 ESSENTIAL Considerations for Truck Radar Systems

Remember that even the best truck radar systems may have some limitations. Here are 4 things you MUST know before buying these systems:

  • A sensor-based system doesn’t detect stationary objects. That means it will not trigger an alert if a parked car, guard rails, or poles are in its view.
  • You should never rely entirely on an advanced driving assistance system, including truck radars. Always combine this technology with your safety driving practices for the best outcomes.
  • Always test the system after its installation before heading to a busy highway. This tip can minimize the chances of crashes in case the sensors don’t work.
  • Not every model may have advanced features, like parking assistance, GPS navigation, etc. Read your product manual to understand your system’s functions and features.
