K3-440 Truck Obstacle Avoidance System
As a truck driver, one always worries about the nearby small vehicles. And for a good reason. Your truck’s large blind spots, especially in the front and rear, makes it almost impossible to see small vehicles and objects. You know what the worst part is? Your side-view and rear-view mirrors can’t help in this either.
However, what can help is the K3-440 truck obstacle avoidance system. It covers both front and rear blind spots of your vehicle and triggers real-time alerts to keep you updated. Pretty cool, right? And that’s only scratching the surface. The system is an all-in-one solution to prevent truck accidents that lead to devastating injuries.
How Does the K3-440 Truck Obstacle Avoidance System Work?
The K3-440 uses sensors and an advanced obstacle avoidance algorithm. These sensors monitor front and rear blind spots using microwaves. Once an oncoming vehicle or a stationary object is detected, the waves are reflected back to the system. The smart algorithms calculate the distance and speed of the obstacle to determine whether it’s a threat.
Having an extra pair of eyes on the road enables you to make better decisions. Remember, truck collisions don’t just damage you and your vehicle. They can also injure others due to the truck’s large size and heavy build. Hence, this obstacle avoidance system ensures your and others’ safety, promoting a stress-free driving and working environment.

Key Features of the K3-440 Truck Obstacle Avoidance System
Our K3-440 truck obstacle avoidance is a feature-rich system. But, let us tell you its key features:
Universal Fit
Whether you are a road or workplace driver, our K3-440 truck obstacle avoidance system can help you. It comes in a universal fit, making it compatible for various large-scale vehicles. That includes commercial trucks, semi-trucks, dump trucks, mining cars, construction vehicles, service cars, engineer trucks, forklifts, etc.
The best part? You don’t need any additional components or services to install this system in your truck. Simply install it following our product manual, and you are all set!
Driver-Friendly Device
Do you want an advanced driving assistant system with a simpler learning curve? Our K3-440 has you covered. The system lets you change its settings, including warning modes and detection levels. Also, you can quickly shift between English and Chinese, depending on your preferences.
Decent Detection Range & Accuracy
The system offers maximum accuracy for detecting nearby stationary objects and moving vehicles. Its precise detection ensures you never receive false alarms that can overwhelm drivers.
Also, the vertical detection range can be set up to 40m. The horizontal detection offers a maximum capability of 8m. Combine this large area coverage with the good accuracy, and you have an effective solution!
Multi-level Warnings
Our K3-440 ensures you stay updated on your surroundings. It uses 3 warning levels to keep you ready for a critical situation. The first level only lights up the digital screen in green, indicating a potential threat is present at a sufficient distance.
If the distance closes, the screen turns yellow and the buzzer starts ringing with intervals. This mode completely changes when the system initiates the level 3 warning. The screen becomes red and the buzzer produces longer warning sounds without intervals. It ensures you get attentive and take action to avoid a potential collision.

Our rear and forward collision-avoidance assist keeps you safe on the road and workplace. The sensors emit waves to monitor the area, ensuring you focus on driving. Its easy installation, usage, and maintenance make it suitable for beginners and experienced drivers alike.
Here are all the key functions of our K3-440 truck obstacle avoidance assist:
1. Usable Anytime, Anywhere
Our microwave sensors are more powerful than traditional cameras, especially in rough workplaces like mining terrains. Why is that? Because they don’t need a clear environment to work effectively.
The sensors remain functional during rain and fog. Even outdoor working environments like dust and debris are ineffective to the system. Also, the sensors don’t require proper lighting. They work just as efficiently at night as they do during the day.
2. Eliminates Two Dangerous Blind Spots
Remember, your truck’s immediate front and rear are two of its most dangerous blind spots. The driver cabin’s height and the truck’s build make it nearly impossible to view oncoming vehicles and small objects in these areas.
However, our microwave sensors keep you updated as they cover both blind spots. So, you will get real-time alerts if the sensors detect any object in the proximity.
3. Two Warning Modes
Do you drive on the road and workplace? Our K3-440 system can make your truck versatile. It has two warning modes, suitable for different conditions.
The “All Early Warning” mode provides alerts for vehicles at different distances. It operates at three alarm levels, ranging from 0.2 to 40m. This mode is suitable for indoor and outdoor workplaces since several workers, vehicles, and other resources are present in the area.
Alternatively, the “Approach” mode only triggers warnings for vehicles closing in on your truck. Hence, it is ideal for driving on busy roads and highways to detect oncoming cars, motorcycles, etc.
4. Export Log & Time Zones
The touch-screen mainframe makes it easier to configure the system. It has various options like adjusting the time zone. You can set the system to your local time. It complements the GPS module integrated into the system to fetch your exact location, speed, and time.
Even better, the system allows exporting your recent warning log. We offer a TF card on the customer’s demand to download and store their log. It works as evidence against false insurance claims, accident disputes, and legal proceedings.

Installing our K3-440 rear and forward collision-avoidance assist is quite straightforward. The product manual offers in-depth steps and specific instructions. That said, here’s a quick installation guide:
Sensors
First, let’s start with the sensors. There’s no exact location for installing sensors. It can vary depending on your vehicle’s type and build. Here’s what you need to do:
- Choose an installation location on the front and one on the rear. Ensure the sensors are mounted 0.5-1.5m above the ground.
- Clean the mounting location and the sensor’s body using a soft cloth.
- Drill holes and install the mounting brackets in both locations. There’s a small triangle on the front of the sensors. Mount the sensors on the bracket, keeping the triangle face upward.
Mainframe and Cables
Now, it’s time to set up the touch-screen mainframe. You can simply place it on the truck’s dashboard in a secure position. Here’s what to do next:
- Connect the 1-to-2 sensor wire to both sensors. If the default wire is short, use the sensor extension cord. Route it back and connect it to the touch-screen mainframe.
- Now, link one end of the power cord to the mainframe and the other to your truck’s power source.
- Lastly, connect the GPS module to your touchscreen mainframe.
Now, everything is in its place. Start the system and test all components!
