Your Car's New Co-Pilot, ADAS: How does it works

Traffic jams, distracted drivers, and unexpected obstacles are just a few of the hazards we encounter. But what if your car could have a sixth sense, a built-in guardian angel to watch your back?

ADAS(Advanced Driver Assistance Systems) are made up of sensors. These little electronic eyes and ears are constantly scanning the road, looking for potential threats. There are cameras to see, radar to sense objects, and even lasers (yep, like something out of a sci-fi movie) to create a 3D map of your surroundings.

The car's sensors, mainly radar, lidar, and cameras gather information about the surrounding environment. Each of these sensors has a unique role:

Radar (Radio Detection and Ranging): Radar sensors use radio waves to detect objects and measure their distance and speed. They are particularly effective in adverse weather conditions like rain, fog, or snow. Radar sensors are typically made of a transmitter, receiver, and an antenna. They send out radio waves and measure the time it takes for the waves to bounce back from objects, calculating distance and speed. how ADAS works in cars Radar sensors are often mounted behind the front bumper. This location is ideal for detecting objects and vehicles ahead, enabling features like adaptive cruise control and forward collision warning.

Rear-mounted radar sensors assist with blind-spot monitoring, rear cross-traffic alert, and parking assistance. Some cars have radar sensors in the side mirrors to enhance blind-spot detection and lane-change assistance.

Lidar (Light Detection and Ranging): Lidar sensors use laser beams to create a detailed 3D map of the environment. They measure the time it takes for the laser beams to hit an object and reflect back. Lidar sensors are composed of a laser, a scanner, and a specialized GPS receiver. They are known for their high precision and accuracy in detecting the shape and distance of objects. lidar sensors.jpg In some autonomous vehicles and advanced prototypes, lidar sensors are mounted on the roof to provide a 360-degree view. This elevated position helps create a detailed map of the surrounding environment.. For a more discreet look, lidar sensors can be integrated into the front grille. This location still offers a wide field of view for detecting objects and obstacles ahead.

Cameras: Cameras capture visual information, which is used to recognize objects, read traffic signs, and detect lane markings. These cameras are often mounted around the vehicle to provide a 360-degree view. 360 cameras in car.jpg

How ADAS works

Once this sensory data is collected, it is transferred to the car's central processing unit (CPU), often referred to as the Electronic Control Unit (ECU). The ECU acts as the brain of the car, processing the data and making real-time decisions to ensure safety and efficiency.

As of now, they have enabled vehicles to achieve Level 2 autonomy. This means the car can control both steering and acceleration/deceleration, but a human driver must be ready to take control at any moment. Level 2 systems include features like adaptive cruise control, lane-keeping assist, and automatic emergency braking. Even Tesla's Autopilot and FSD systems are classified as Level 2 autonomous driving according to the SAE (Society of Automotive Engineers) scale. This level indicates that the system can perform certain driving tasks but requires human oversight and intervention.

ADAS level of Indian Vehicles

The Indian automotive market is witnessing a surge in Advanced Driver Assistance Systems (ADAS), primarily within the Level 1 and Level 2 autonomy categories defined by the Society of Automotive Engineers (SAE). Models like the Tata Safari and Mahindra XUV700 offer Level 2 autonomy, equipped with features such as Adaptive Cruise Control (ACC), Lane Keep Assist (LKA), Automatic Emergency Braking (AEB), Blind Spot Detection (BSD), and Traffic Sign Recognition (TSR). These systems enable more hands-off driving, particularly on highways, but constant driver attention remains crucial.

Hyundai and Kia models, including the Creta, Tucson, and Seltos, typically feature Level 1 ADAS with functionalities like Blind Spot Detection (BSD), Rear Cross-Traffic Alert (RCTA), Driver Attention Warning (DAW), Lane Departure Warning (LDW), and Forward Collision Warning (FCW).
