Car blind spot monitoring 77G H1

The 77G-H1 blind spot detection systems have microwave sensors. They have a place at both sides of the car’s rear bumper. It has a 50m detection range and alarms in multiple ways if any non-stationary object gets in the way. Basically, the sensors emit electromagnetic waves in the 50m range. When a car or other objects disturbs the waves, it sends a signal to the driver indicating an obstacle near the car.

The blind spot sensors are active only if the vehicle moves at speed higher than 10Km/h. When turned on, they detect the nearby moving vehicles and alert the driver of the car’s presence. The LED indicators in the side mirrors illuminate in the presence of a moving vehicle. On top of that, these visual indicators emit audible beeping sounds in the case of a level 2 warning.

Introduction

Even a minor car scratch could spoil a person’s mood for a day. So, imagine if a car gets a hit from the side or behind. Yes, it’s pervasive despite the clear rear-view and side-view mirrors. How so? All cars and motorbikes have blind spots. You can’t view full car in the mirrors, not even in cameras.

Therefore, we use blind spot monitors. Modern vehicles have a built-in blind spot monitor to cover the car blind spots. However, older models don’t have it. If your vehicle is missing one, you can install one yourself. It’s super simple to install. Just read the article, and you will get complete understanding of 77G-H1 blind spot monitoring systems.

77G-H1 Blind Spot Monitor’s Advantages

Its aim is to detect objects near the car’s blind spots to prevent accidents, especially during lane changing. The rear-view and side mirrors won’t correctly show the adjacent passing cars when switching lanes or reversing a vehicle. Therefore, you turn your head and see an upcoming vehicle before changing lanes.

However, the days when you had to turn your head each time changing lanes are hereby over. In modern times, the blind spot monitor sensors will alarm you if there is an object in the car’s blind spots. There are multiple warning levels depending on the situation. We will discuss those later in the article. For now, let’s discuss how the cars with blind spot detection assist.

  • Reduces car accidents: The blind spot monitor sensors cover a wide area around your vehicle. So, whenever any object gets really close to your car, it alarms you through LED lights and sounds to prevent a crash.
  • Improves driving awareness: Sometimes, late-night sleep or dizziness affects your driving. However, with blind spot monitors, you are always aware of your surrounding, no matter the condition of your mind.
  • Assists driving in bad weather: The blind spot monitoring sensors detect objects even in smoke, fog, and dust. They are useful in times when you don’t see your surroundings due to bad weather.
  • Ease in driving larger vehicles: The larger vehicles have more blind spots and are harder to see around them. So, we use a blind spot monitor kit to get peace of mind driving.

What Are Blind Spot Warnings? What Do They Tell You?

car universal blind spot monitor 77G H1

The cars with blind spot detection have two warning levels, indicating the danger level. If the danger is low, the level 1 warning turns on. Likewise, if the danger level is high, a level 2 warning starts.

In the case of level 1 warning, the LED lights in the side mirrors illuminate, indicating a vehicle in the surrounding. On the other hand, if the vehicle is in your car’s surroundings and you turn on the indicator, the LED illuminates along with a buzzer. They will provide visual and audible blind spot warnings assuming you have missed the illuminated LED light.

77G-H1 Blind Spot Monitor’s Functions

The 77G-H1 blind spot detection systems come with four functions:

  1. Blind Spot Detection (BSD)

    car universal blind spot monitor 77G H1

(Detection Range: Horizontally 4 meters and longitudinally 15 meters)

The blind spot detection turns on when the car speed is higher than 10Km/h. if a non-stationary object comes under the radar’s range, it will produce a level 1 warning if the turning indicator is not flashing. The level 1 warning is active until the object leaves the radar’s range.

However, if the object approaches the vehicle at a higher speed and your car’s turning indicator is on, the blind spot monitor will produce a level 2 warning. The light and a beep sound will alert you until the vehicle leaves the radar’s range.

  1. Lane Change Assistance (LCA)

car universal blind spot monitor 77G H1

(Detection Range: Horizontally 4 meters and longitudinally 50 meters)

The LCA turns on when you start your vehicle’s engine. It has an alarming range in the adjacent lines. If a non-stationary object enters the radar’s coverage with a collision time <3.5 seconds, the pre-warning mode starts.

When a car enters the alarming range with your turning indicator off, the LCA will produce a level 1 warning. The warning cancels when the car leaves the adjacent lane alarming scope. In case if your turning indicator is on with a vehicle in your adjoining lane, the LCA will produce a level 2 warning. You will get an alert from the LED and the buzzer’s sound, indicating danger if you turn your vehicle. The level 2 warning cancels when the adjacent car leaves the alarming range.

  1. Rear Cross Traffic Alert (RCTA)

(Detection Range: Horizontally 5 meters and longitudinally 5 meters)

car universal blind spot monitor 77G H1

The Rear Cross Traffic Alert (RCTA) is a reverse gear warning. It detects objects coming from the car’s rear side. Normally, when the vehicle is in parking, the left and right sides of your car will have other vehicles. So, the object crossing from behind is unidentifiable and leads to collision. In such cases, the RCTA function will help.

Whenever you put a reverse gear, the RCTA function gets active. If an object comes in the alarm zone when reversing, the RCTA will directly generate a level 2 warning. The LED lights and a buzzer sound will alert you until the object leaves the alarm zone.

  1. Active Overtaking Alert (AOA)

car universal blind spot monitor 77G H1

(Detection Range: Horizontally 4 meters and longitudinally 15 meters)

The Active Overtaking Alert (AOA) prevents post-overtaking collisions. When the vehicle fails to full overtake the passing car, it may result in a rear-end collision. So, we use AOA function in such cases.

The AOA gets active when your vehicle overtakes the passing left and right cars. When overtaking, the warning lights will be on until your car reach a safe zone; It’s a level 1 warning. However, if your car hasn’t reached a safe zone and you turn the indicator on, the AOA will produce level 2 warning. It will alert you through LED light followed by a buzzer sound.

How To Install A Blind Spot Detection System?

What Are The Tips For Using Blind Spot Monitors?

Undoubtedly, they are sensors and provide warnings in case of any nearby objects. However, you must know these tips to avoid malfunctions of blind spot monitors. In order to maximize its effectiveness, we recommend:

  • Understand the system’s limits

Know the limitations of your blind spot monitor cars. They have a specific limit before turning on. So, check whether the turning-on limits suit your driving. For example, if your car’s blind spot monitor starts working at 30 Km/h, you won’t get the alarms if you drive slower. On top of that, some blind spot monitors won’t detect pedestrians, pets, and cyclists. So, check the operation manuals before trusting the detection systems.

  • Test the LED and Buzzer Alarms

A slight unplug could result in a malfunction of your car’s blind spot monitor. Suppose you have not connected the LED lights with the power line; it won’t illuminate even if the sensors detect an object. So, it’s always recommended to test the blind spot monitors beforehand.

  • Trust your eyes

Putting all your trust in sensors isn’t a good practice. Whenever in reverse, check the objects behind your car in the mirrors. Likewise, if you are changing a lane, check your side mirrors. The blind spot monitors are for extra safety and cases when you don’t see the objects in the mirrors. So, don’t rely on the detection systems only.

  • Turn-off option

If you are stuck in a traffic jam or the alarm sound annoys you, there is an option to turn-off the blind spot monitor in the infotainment system. After a traffic jam, you can turn it on – it’s just a matter of some minutes.

Adding blind spot monitoring systems aids in driving and is an extra layer of safety for passengers. Sometimes, the passing vehicles are in the car’s blind spots; they aren’t visible to the driver’s eyes. In such cases, the cars with blind spot cameras and sensors alarm you through LEDs or a buzzer sound.
