How AI has played a key role in development of ADAS technology

Artificial Intelligence (AI) has already started to penetrate at every level in a common man’s life and it is bound to shape the future of almost every industry including automobiles. AI will play a crucial role on multiple fronts in the global automotive industry but its actual application in a vehicle’s primary purpose, i.e., moving from point A to point B, will be implementation of more advanced autonomous technology.

Currently, Level 2 is the highest level available in the Indian mass-market car space that essentially offer semi-autonomous features that work in the constant state of driver’s attention and intervention. Level 5 is the highest where the car is capable of full self-driving (FSD) technology, something Tesla has been working on for so many years. 

Role of Machine Learning in ADAS

All levels of autonomous features work on machine learning (ML) which is a subset of AI. An Advanced Driver Assistance System (ADAS) module is developed with the help of ML which helps in collecting a large set of data along with relevant insights extracted by computers. These datasets are then converted into ML algorithms which can then be used to inform forecasts and decisions.

Here are a few examples of ADAS features that make use of Machine Learning:

1. Autonomous Emergency Braking (AEB): If a driver fails to respond to a hazard, ML algorithms process sensor data to evaluate the risk and automatically apply the brakes to avoid or mitigate a collision.
2. Lane-Keeping Assist: By leveraging cameras and machine learning, ADAS can detect lane markings and provide subtle steering inputs to help keep the vehicle centered within its lane.
3. Driver Monitoring System: Machine learning tracks the driver’s behavior and attentiveness, identifying signs of distraction or fatigue, and issues warnings or takes preventive actions to enhance safety.
4. Adaptive Headlights: Using machine learning, ADAS can adjust headlight direction based on road curves and surrounding traffic, improving visibility while reducing glare for oncoming vehicles.
5. Traffic Sign Recognition: Machine learning enables ADAS to detect and interpret road signs—such as speed limits, stop signs, and no-entry warnings—and alert the driver with visual or audible signals when needed.

Benefits of Machine Learning in ADAS

Here’s how Machine Learning boosts the effectiveness of ADAS

1. Decision Making: Leveraging complex data inputs—such as traffic density, weather, and road conditions—ML empowers ADAS to make fast, context-aware decisions for enhanced driving safety.
2. Predictive Analytics: By analyzing historical data, machine learning forecasts potential threats, enabling ADAS to anticipate and help avoid dangerous situations.
3. Object Recognition and Tracking: Machine learning processes sensor data in real-time to identify and track vehicles, pedestrians, and obstacles, allowing ADAS to make informed decisions such as braking or steering to ensure safety.
4. Anomaly Detection: ML models detect unusual driving behavior, like sudden lane changes, which may signal potential hazards. ADAS can respond proactively to prevent accidents.
5. Adaptive Control: ML allows ADAS to adjust system settings based on driver behavior, traffic flow, and environmental conditions, offering a more personalized and efficient driving experience.

Future prospects and challenges of AI & ML in ADAS

1. Sensor accuracy: Quality and accuracy of sensors used in ADAS is very critical for generating reliable AI algorithms. Also for efficient machine learning, future ADAS modules will require a large quantity of high-quality data which will be a big task.
2. Human-Machine Interaction: As ADAS systems grow more autonomous, the challenge is to ensure seamless and intuitive communication between the driver and the system.
3. Environmental Adaptability & Safety: To handle diverse environmental conditions and scenarios, machine learning models must be both reliable and resilient. Earning public trust hinges on prioritizing the safety and integrity of the ADAS above all else.
4. Ethical & Legal Considerations: The extensive use of AI in ADAS already presents a grey area, especially those pertaining to data privacy. Also, liability in the event of accidents will result in a number of intricate regulatory and legal issues.

It is safe to predict that more powerful and hopefully more accurate ADAS systems are on cards with the development of more sophisticated and robust Machine Learning tools that will help generate a wide range of algorithms. While we have already seen the use of fully autonomous driving being implemented in Tesla, more development in this field will help democratize ADAS in affordable vehicles going forward.
