WHAT IS ADAS IN CARS

The ADAS or ADAS full form of 'Advanced Driver Assistance System' has long been a much-talked-about set of technologies enabled by a human-machine interface aimed at assisting drivers. ADAS driver assistance is undoubtedly the need of the hour, especially because road traffic crashes remain a foremost cause of death due to unintended injuries.

While driving assistance systems certainly enhance driving convenience, automate car safety, reduce driver errors, minimize accident risks and bring down the number of deaths or injuries, the ADAS as a concept needs a layman's explanation.

Let's explore the auto ADAS in cars, its functioning, benefits, types, levels, critical components, applications, and features. We'll also understand how artificial intelligence and machine learning (AI & ML) may revolutionize the upcoming advanced driver assistance systems.

 

 

What is ADAS?

The advanced driver assistance system is a collection of electronic automotive technologies and features that utilize sensors, cameras or radars to assist drivers.

How Does ADAS Work?

ADAS extracts the best out of innovative technologies, strategically places multiple camera-based sensors or radars, monitors environments around the car, provides crucial inputs, detects driving obstacles, warns of potential dangers and takes corrective measures.

Why is ADAS Important?

Advanced driving assistance systems increase driver alertness, improve situational awareness, bring more comfort, positively influence driving styles, enhance decision-making, reduce errors, lead to lower maintenance costs plus less fuel consumption, prevent accidents and translate into better overall road safety.

 

Types & Levels in ADAS

Passive ADAS

Passive ADAS systems in cars, like the Anti-lock Braking System, Traction Control System or Electronic Stability Control, provide alerts and real-time data. They make drivers aware of less-than-safe conditions without taking proactive actions.

Active ADAS

Active ADAS systems such as Lane-keeping Assist, Adaptive Cruise Control or Automatic Emergency Braking are also described as "Autonomous Driver Assistance Systems." They take control of cars in emergencies, carry out corrective measures and help avoid accidents.

ADAS Level 1: The First Level of Automation

• Driver assistance via passive systems.
• Systems take control of specific driving functions.
• A part of cars with adaptive cruise control.

ADAS Level 2: The Partial Driving Automation

• Systems control steering, acceleration and deceleration.
• Drivers remain attentive.
• A part of cars with features like lane-keeping assist and auto parking.

ADAS Level 3: Conditional Driving Automation

• Here, the systems use driver assistance functions and artificial intelligence.
• They take control of steering, braking and acceleration.
• Systems alert drivers when the controls are to be taken back.

ADAS Level 4: High Driving Automation

• In many circumstances, cars get complete control.
• Drivers can manually regain control.
• Cars become self-driven and restricted to particular areas.

 

ADAS System in Cars: Key Components

The ECU (Electronic Control Unit) for data processing and decision-making.

Software & Algorithms for analyzing images and interpreting sensor data.

Info-display & Human-Machine Interface (HMI) communicate ADAS information and interact with its functions.

In-vehicle Network for connecting ADAS components.

GPS & Navigation Systems for accurate positioning, navigation, and route planning.

Front/Rear/Surround-view Cameras for implementing functions like Lane-keep Assist, working with reversing assistance, blind spot monitoring and automatic parking functions.

Front/Side Radars for speed tracking and distance measurement.

Lidar, light detection and ranging remote sensing for autonomous driving and precise object detection.

Ultrasonic Sensors for short-range detection, detecting obstacles and parking assistance.

 

Top ADAS Applications & Features

ABS or Anti-lock Braking System: Prevents skidding and locking-up.

AEB or Automatic Emergency Braking: Detects potential impacts to apply brakes automatically and prevent collisions.

FCW or Forward Collision Warning: Utilizes visual/auditory signals to inform drivers of impending collisions.

BSD or Blind Spot Detection: Provides imminent-collision warnings while changing lanes and lets you have blind spots in view.

ESC or Electronic Stability Control: Addresses loss of control during sudden steering maneuvers and stabilizes the car on its intended path.

Parking Assist: Ensures safe/accurate perpendicular and parallel parking with the help of software, cameras and sensors.

Traffic Sign Recognition: Warns drivers by identifying road signs.

LKA or Lane-keep Assist: Keeps your car in the centre-lane by offering steering inputs/alerts.

ACC or Adaptive Cruise Control: Enables safe distances by matching car speeds.

TCS or Traction Control System: Integrates ESC and ABS for stopping car wheels from losing traction.

 

Future of ADAS with AI & ML

It is nearly impossible to downplay the relevance of auto ADAS in reducing road accident fatalities. Fast-evolving advanced driving assistance systems employ artificial intelligence algorithms and machine learning for interpreting data from sensors, cameras or radars.

AI also facilitates predictive maintenance models capable of anticipating upcoming issues, optimizes fuel efficiency, and upgrades your car's performance.

To an extent, the advanced driver assistance systems are still regarded as ongoing projects with a substantial scope of refinements. While there is no shortage of sceptics with valid concerns, AI and ML, in conjunction with ADAS, are set to produce remarkable advancements in car efficiency and autonomy while transforming traffic safety.

Whether it is the economy segment, expensive cars, or electric cars, unpredictable driving hazards mean the demand for ADAS cars in India will likely grow exponentially. A wisely chosen car insurance provides the much-needed financial safeguard against losses or damages due to natural or human made causes. Globally acknowledged comparison brokers such as QuickInsure facilitate the in-depth analysis of policies and their benefits and help you finalize the appropriate cover for your car.

ADAS - FAQs

1. Is ADAS only Available in Luxury Cars?

No, advanced driving assistance systems are now available in relatively affordable cars and the mass market segment.

2. Do all ADAS Features Work in Bad Weather?

Please note that many ADAS features do not work properly under all weather conditions; some applications' performance, owing to their limitations, may get adversely impacted, and others could be entirely disabled.

3. Can ADAS be Installed in Older Cars?

Yes, some driver assistance systems, based on compatibility checks, modification requirements and professional advice, may be integrated into older cars as aftermarket ADAS solutions.

4. What's the Difference Between DAS and ADAS?

When it comes to ensuring comfortable and safer driving experiences, DAS or the Driver Assistance System can be described as a relatively simple or fundamental technology. ADAS, on the other hand, must be seen as a state-of-the-art and more futuristic solution.

5. What is Level 1 ADAS?

It's the starting level of automation where advanced driver assistance systems take charge of specified driving functions.

6. What is Level 2 ADAS?

The Level 2 ADAS system takes a significant step towards completely autonomous cars where your vehicle controls steering, acceleration and deceleration but necessitates the driver to remain attentive in the driver's seat.

7. What is Level 3 ADAS?

As the third level of autonomous driving, Level 3 ADAS provides conditional driving automation where cars utilize a variety of driver assistance functions and artificial intelligence to make informed decisions, permitting drivers to get involved in other activities.
