Complete Guide Of A 77G H3 Car blind spot information system
“Speeding thrills but kills.” – A true proverb indeed. But, do you know what the greater danger is? The reckless driving! Every day numerous cars merge into other vehicles because of careless drivers. Therefore, A driver must monitor every inch of the road for safety.
The question arises; how would drivers monitor the surroundings around them? Well, they can’t, at least not on their own, and that’s a fact. The reason is the design of every car. The metal pillars around the drivers make it impossible to examine the car round, making the driver vulnerable to crashes.
There is a solution to this problem! And it is not a complicated and expensive one. Yet, a simple, budget-friendly, and effective fix. Every car has a different design, but the solution remains the same throughout the car variants; the car blind spot information system. It’s a driving assistance system everyone needs. This system monitors the spots that a driver cannot reach. Moreover, it warns the driving individual if a target object enters the detection area. So, the driver becomes cautious, saving the car from any possible collision.
How Does A 77G H3 Car Blind Spot Information System Work?
Working a 77G H3 car blind spot information system is simple. Our product package has a 77Ghz millimeter wave radar, two indicator lights, a buzzer, a host box, and a connecting harness. All these components work collectively for the proper functioning of the system. The complete mechanism of working of a 77G H3 blind spot car detection system is as follows:
Working Principle Of A 77G H3 car blind spot information system:
The system performs two main functions. One is detecting the target object, and the other is warning the driver about them. The millimeter wave radar accurately detects the objects. At the same time, the warning lights and buzzer collectively warn the driver about the risk.
A 77Ghz millimeter wave radar emits the wave signals. Any vehicle in the range of these signals creates a disturbance, and this interference helps the car blind spot sensor detect the respective object. After the detection, it is up to the car blind spot information system to judge whether the object is a threat to the car or not. For practical judgment, it accurately measures the target car’s speed, angle, and relative displacement.
Once the system marks the target as a potential risk, the system issues a first or second-level alarm to warn the driver.
- First level alarm: In this warning mode, the warning light will stay on without the involvement of a buzzer.
- Second level alarm: The warning indicator light flashes, and the buzzer sounds.
The 77GHz millimeter wave radar can detect 64 objects simultaneously within a 50-meter radius. For that reason, we label it as the most efficient and accurate car blind spot information system.

What Are The Functions Of the 77G H3 Car Blind Spot Information System?
Usual blind spot systems perform the same basic functions of detection and alerting. However, the 77G H3 car blind spot information system goes another step further with the additional distinctive features. The features like self-inspection, BSD, LCA, and RCW help our product be unique in the market. It is better to know how all these functions work, which will help the owner get the most out of the system.
Once the ACC powers on, the system will immediately turn on. Moreover, if the driver turns the ignition off, the radar stops working. The system is always in first-level early alarm mode, except when the driver switches on the turn signal lamp or engages with the reverse R gear and double flashing warning lights.
Product Self Inspection:
Once you install the car blind spot information system in your car, it becomes a vital part of your every journey. So, it is essential to check whether the system is working normally or not before jumping on the road. Our 77G H3 blind spot system has this ability, making it optimum for every car. The system gives different indications at different states of the system as follows.
Normal State Of The Car Blind Spot Information System:
- After powering on the vehicle, the left and right indicator lights flash 3 times.
- When the car speed exceeds 15km/h with an object in its detection area, the system will alert the driver accordingly. If you turn to prepare for a lane change,At this state, indicator lights will start flashing, and Steering signal trigger the steering buzzer will make a sound.
Both of these signs guarantee the proper functioning of the system.
Abnormal State Of The Car Blind Spot Information System:
- If the left and right indicator lamps flash once, it indicates that the control box is normal and the radar is abnormal.
- As the radar is not working properly, the indicator light will always stay off. To fix the error, check whether the power-on signal works correctly or not.
Blind Area Monitoring Function (BSD):
The car blind spot information system will start functioning when the vehicle speed is ≥15Km/h. The detection range of the system for BSD is different than other features. Its horizontal range is 1.5m≤X≤4.4m,-4.4m ≤ x ≤-1.6m. However, the longitudinal range is 0 m≤Y≤6.5m
Blind Spot Warning Modes Of Car Blind Spot Information System:
- The system will give a first-class alarm when detecting the target object, while the car does not switch the turn signal on. Once the object leaves the area, the system will cancel the alarm.
- If the driver switches on the turn signal lamp while an object is in the detection area, the system issues a second class alarm. Once the object leaves the alarm area, the system will cancel the warning alarm.
The BSD feature of the car blind spot information system helps in active and passive overtaking. But, the relative overtaking speed must not be more than 20km/h.
Parallel Auxillary Approach (LCA):
This system helps the driver in active lane changing. It warns the driver early about the object in the adjacent lane. In LCA parallel auxiliary feature, the system adopts an early warning strategy. So, it alerts the driver when the approach time of the vehicle is ≤ 4.0 seconds.
The function starts once the car’s speed is ≥15Km/h. 1.5m≤X≤4.4m,-4.4m ≤ x ≤-1.6m, and 0m < y ≤ 50m are the horizontal and longitudinal ranges of early warning LCA.
LCA Modes of A 77G H3 Car Blind Spot Information System:
- When the target enters the alarm area and the driver does not switch on th
e turn signal, the car blind spot information system issues a first-class alarm, which gets canceled once the object leaves the area. - When the target enters the signal range, and while the turn signal is switched on, the system issues a second-class alarm until the object leaves the area.
Rear Collision Warning Function (RCW):
In RCW, the car blind spot information system warns the driver about the approaching object in the lane directly behind the vehicle. Both left and right LED lights flash to alert the driver, helping to react quickly.
The feature starts when the car speed is ≥2Km/h. The horizontal range of early warning is -1.6m ≤ x ≤ 1.6m. In comparison, the longitudinal range of the detection area is 10m < y ≤ 50m. In the early warning strategy of the RCW function, the minimum vehicle approach time is ≤ 1.5s.
