The majority of cars these days are equipped with this safety feature! 

Understanding ADAS

With technological advancements in our Indian automobile industry, our vehicles are becoming smart, capable, and safer, of course! While there are multiple technological advancements, ADAS has been the prominent one. 

Wondering what is ADAS in full form? ADAS, which stands for Advanced Driver Assistance System is a commonly found technology in most cars today. And if you own a car that is not older than a decade, chances are that it might have some kind of ADAS features. This tech uses sensors, cameras, and detection systems to assist drivers and prevent accidents caused by human errors.

There are various levels of Advanced Driver Assistance Systems automation, ranging from a simple reverse parking sensor to fully automated parking assistance. If you are scratching your head and wondering how ADAS works, and what features it includes, read on to get every answer!

How Does ADAS Work?

How Does ADAS Work

The Advanced Driver Assistance System is a combination that uses several small components including the sensors, interfaces, controllers, and powerful processors. These components work in sync to analyse, combine, and process the real-time data to assist the driver while minimizing the risk of accidents. 

Common sensors used in ADAS-equipped vehicles are Long-range RADAR, LiDAR, SONAR, etc. These sensors work alongside the imaging solutions such as 360-degree cameras that constantly monitor the surroundings of the vehicle. The data collected is then sent to the onboard computer which processes the data in a fraction of a second, enabling the decisions to be made faster than a human reaction time.

What Features Fall Under ADAS?

As we know driving a car is a combination of attention and reflex. The modern-day ADAS is therefore suited to achieve both these abilities and hence is divided into different features. Here’s what each feature clarifies: 

ADAS Feature

 

Meaning

Collision Intervention Systems

Constantly detects the road around the vehicle to prevent any incoming collisions.  

Automatic Emergency Braking (AEB)

Detects potential collision obstacles, displays the warning on screen and applies brakes if there’s no human intervention. 

Automatic Emergency Steering

This feature works in conjunction with AEB to steer away from the obstacle to avoid collision. 

Rear Cross Traffic Collision and Automatic Reverse Braking 

Detects and displays a warning of collision if the car is reversing. It applies brakes if human intervention is delayed or missing.

Blindspot Alert and Avoidance

Alerts about a vehicle that may not be directly visible and avoids the vehicle to go near that passing vehicle (if the feature is activated).

Forward Collision Alert

Warns the driver about a potential collision with a vehicle ahead.

Lane Departure Alert

Alerts about the vehicle departing from its lane. 

Parking Collision Alert

Detects the potential collision with an obstacle during parking a car.

Adaptive Cruise Control

Adjusts the acceleration or braking according to the vehicle ahead. 

Active Drive Assist

Assists the steering, braking, and accelerations based on the surrounding conditions.

Traffic Sign Recognition

Uses cameras to recognise the traffic signs and symbols and alerts the driver to act in that direction.

Lane Keep Assist

Steers the vehicle back on the lane if it loses its track. 

Parking Assist

Uses cameras and sensors to park a vehicle, either automatically or with some manual inputs.

Speed Alerts

 

Alerts the driver when the vehicle overspeeds.

Driver Drowsiness Detection

Uses sensors to monitor the driver’s performance and vehicle behavior to alert the driver about being drowsy.

Safe Exit Warning

 

Warns all passengers in the car if they open a door suddenly near passing traffic.

Levels Of ADAS

Levels Of ADAS

Since we have talked about ADAS full form, its meanings, and the features it involves, lets now discuss the levels of ADAS as developed by the SAE (The Society of Automotive Engineers International). It is important to note that only Level 2 and below ADAS equipped cars can be found in India.

Advantages Of Using ADAS Technology

‘Advanced Driver Assistance Systems,’ as the term suggests, improves safety and avoids and/or prevents accidents, which a human eye might miss. It can identify the events or obstacles which might cause an accident. The system ensures:

  • Increased vehicle safety: It helps avoid collisions by detecting vehicle’s blind spots, giving forward collision warning, and by AEB. 

  • Driver’s safety and convenience: ADAS reduces the chance of driver’s fatigue by providing features like adaptive cruise control. It also provides great assistance for parking.

  • Increase in fuel efficiency- it offers adaptive cruise control, lane-keep assist, and predictive braking which reduces the fuel consumption. Adaptive cruise control lets the vehicle be driven at a constant speed while minimizing acceleration and brakings, in return increasing the fuel economy.

What Are The Limitations Faced By ADAS In India?

What Are The Limitations Faced By ADAS In India

There is no doubt that Advanced Driver Assistance Systems, or ADAS, can help prevent accidents to some extent, but it still face a host of challenges in Indian driving conditions. For example, this technology needs a proper road infrastructure with markings but most local roads have little or no markings at all. 

Then there’s another issue of stray animals wandering onto the roads, which is not that prevalent in much developed countries, making ADAS workability difficult in India. Also who is accountable if an accident occurs? The car’s tech or the driver? On top of that, ADAS may not work properly as it faces limitations due to poor lighting or adverse weather conditions. 

Another critical issue comes with the system’s processors. This is where all the data is collected and processed to make further decisions. Now imagine, what will happen if the processor misinterprets the data. And as we know all systems depend on algorithms and a small glitch with this algorithm can cause significant issues. 

Way Forward For ADAS In India

Way Forward For ADAS In India

The way forward involves addressing key challenges to enhance the effectiveness and reliability of the Advanced Driver Assistance System (ADAS). This includes proper development and maintenance of lane markings on the roads, since some features of ADAS such as lane-keep assist, and lane departure warning rely on these markings. Additionally, India’s diverse road composition including a mix of vehicles, animal carts, stray animals, and pedestrians creates a complex challenge to this technology, requiring advanced algorithms to handle such unique situations. On top of that, unmarked speed bumps, and potholes hardly allow the smooth operation of ADAS. 

Once we are able to address such challenges, we will pave the seamless way for ADAS adoption in India.
