Benefits Of Using A 77G H3B Truck Blind Spot System:

Our truck blind spot system stands up in the crowd of contenders with its specific features and the amount of value it gives to customers.

  • The truck blind spot detection system has a 77GHz microwave radar that emits highly penetrating waves. These waves can penetrate even the harsh weather hindrances and detect the moving vehicles in bad weather conditions. So, our 77G H3B truck blind spot system is an all-weather and all-time application suitable for fog, smoke, and dust.
  • The wave radar in our blind spot monitor kit operates on a higher frequency band, proving accurate to longer distances. Our blind spot system can detect the target up to 50M and alarm the driver about the approaching vehicle.
  • Because of the better technical functionality of our radar system, it can detect up to 64 target objects at a single time. Along with the real-time detection, the truck blind spot system can monitor the speed, angle, and relative displacement of these 64 objects simultaneously.

Reasons To Buy A Truck Blind Spot System:

It is physically impossible for a truck driver to monitor all its surroundings at a 360-degree angle. There are always some blind spots that a driver can miss unintentionally. So, leaving any of the spots on the road unmonitored could cause a possible collision. A truck blind spot detection system minimizes the risks of a truck merging inside other vehicles on the road.

Mounting a truck blind spot system on your vehicle finishes the need to turn your head to monitor the blind spots on the road. It is symbolized as installing an extra pair of eyes on the back of your head. So, it detects and warns you about every moving vehicle 50M behind your truck.

How Does The 77G H3B Truck Blind Spot System Work?

Working principle Of A 77G H3B Truck Blind Spot System:

The working principle of a 77G H3B truck blind spot system is simple. A 77GHz millimeter wave radar emits continuous wave signals. If any moving vehicle comes across the signal range (which is 50M), it interferes with the wave signals, and the radar detects the car as a target object.

Not only that, but the radar accurately measures the speed, angle, and relative displacement of the target vehicle. So, it judges better whether the approaching vehicle is a threat to the truck or not.

After detecting and evaluating the target object, the radar signals the alarm lights that alert the driver about the moving vehicles in blind spots.

Functions Of A 77G H3B Truck Blind Spot System:

Our truck blind spot system has distinctive functions that help it stand out in the crowd. Some of these functions are as follows:

  • Product Self-Inspection:

Our truck blind spot monitors self-inspects the system before a road journey. So, it ensures the proper working of the system with accurate detection and warning procedures.

  1. When the equipment is powered on, the left and right indicator lights flash three times.
  2. Whenever the vehicle speed exceeds 15km/h, and any vehicle is present in the detection area, the indicator lights start flashing and buzzer sounds. It indicates that both the detection and alerting features are working properly.
  • Blind Area Monitoring Function; BSD(blind spot detection):

When the vehicle’s starting speed is more than 15km/h, the horizontal and vertical ranges for the alarm area change. The horizontal range for early warning switches to 1.5m≤X≤4.4m,-4.4m ≤ x ≤-1.6m. At the same time, the longitudinal warning range changes to 0 m≤Y≤6.5m.

With this function, the truck blind spot system equips the early warning strategy. So, it warns the driver about any moving vehicle in the designated alarm area before it becomes a hazard.

The blind area monitoring function assists in active and passive overtaking of the vehicle. The relative overtaking speed for the truck is not more than 20km/h.

truck blind spot systems

The BSD early warning mode has two different conditions:

  1. If the vehicle’s turn signal is off and a target object enters the alarm area, the system triggers a level 1 warning alarm until the object leaves the area.
  2. If the object enters the detection area when the turn signal is on, the system issues a level 2 warning until the target object leaves the area.
  • Parallel Auxillary Approach Early Warning Function -LCA

The parallel auxiliary approach functions warn the driver early about the vehicles in adjacent lanes. Therefore, it helps the truck blind spot system to act as a lane-changing assist and prevents unintentional accidents.

This feature has a designated detection area. The horizontal range for early warning is 1.5m≤X≤4.4m,-4.4m ≤ x ≤-1.6m—same as a BSD early warning mode. In comparison, the longitudinal warning range is 0m < y ≤ 50m.

In the early warning strategy, the truck blind spot system alerts the driver when the approach time of the target is less than 4 seconds.

  1. If the turn signal is on when the target object enters the area, the system generates a level 2 warning alarm. when the object leaves the alarm area,cancle alarm.
  2. However, the outcome changes if the turn signal is off. The object entering the detection area while lane changing results in triggering of level 1 warning alarm ,When the object leaves the area,cancle alarm.

What Are Blind Spots Of A Truck?

Every vehicle on the road has several blind spots. In the case of a truck, the longer length of the car increases the number of blind spots. A truck generally has four main blind spots:

  • Directly in front Of The Truck:

truck blind spot systems 77G H3B

The front of the truck is usually considered a safe sector as the driver is continuously looking ahead. Yet, the portion directly in front of the vehicle is entirely off the eyes of the driver. It depends on the height of the truck. Usually, the portion 2 feet forward and 3 feet above the ground is marked as the blind spot of a truck.

  • Lower Sides Of A Truck:

The structural pillars of a truck make it difficult for the driver to keep an eye on the truck’s sides. That is why both the lower left and right sides of a truck are the places where even the side mirrors cannot help the driver inspect.

  • Rear Sector Of A Truck:

The only possible way for truck drivers to monitor the rear end of the road is to turn their heads. Therefore, they need to take their eyes off the road, which is risky. So, without a truck blind spot system, the drivers can’t examine the vehicle’s rear end.

How To Install 77G H3B Blind Spot Detection System For Trucks?

The installation procedure of a 77G H3B truck blind spot system includes mounting wave radar and line connection across the vehicle.

Line Connection Steps:

  1. Connection of power cord

  • Connect the orange line to the positive pole of the right turn signal lamp.

Radar Installation:

  1. Install the radar at the truck’s tail with an outlet on the top.
  2. truck blind spot system 77G H3bThe installation height of the radar must be 0.75 to 0.95 meters from the ground.
  3. For installation pitch angle, the radar must dip at an angle of 10±2°.
  4. Ensure that the angle between the radar and the vehicle body axis plane is 0±1.5°.
  5. Radar inclination adjustment
  • The first step is a horizontal adjustment. Make sure the radar is parallel to the cross-sectional surface of the
  • vehicle, and the bracket is parallel to the license plate.
  • For the pitch angle adjustment, the mobile phone app “level meter” comes in handy. Attach the mobile to the radar head and tilt it downwards. When the app shows a 10-degree angle, tighten the screw to keep the radar at this position.

What Are The Common Problems With Truck Blind Spot Detection? How To Solve Them?

While operating any truck blind spot system, there are several problems a driver might encounter. Some of them are described below with the solutions to get rid of them.

  1. The left/right indicator light shows an opposite target warning position:

This error can originate if the driver installs the radar or indicator lights upside down. So, check the left and right light signs. Also, check if the radar surface is installed correctly.

  1. In early warning mode, the buzzer has no alarm sound after the detection:

There can be two reasons for this problem. Either the buzzer is on, or it is a turn signal input problem. So, to deal with it, check whether the buzzer is normal or if the signal wiring of the turn signal is on.

  1. After powering on the vehicle, the lights of the truck blind spot system always stay on/off:

LED lamp damage and wiring harness problems can lead to this problem. So, inspect the wiring harness plugging and change the LED lamp for inspection.
