Hello all and welcome to MAE Learning. In this blog, we will explore Advanced Driver Assistance System (ADAS) Level-2 with 22 main features. This technology is making Indian cars smarter and safer.
What is ADAS Level 2?
ADAS Level 2 is a smart safety technology in modern cars. Simply put, it helps the driver by controlling steering, acceleration, and braking together for some time. The car uses cameras, radars and sensors to watch the road and understand the traffic. But always remember, the driver should stay alert and be ready to take control at any time.
This technology is now available in many Indian vehicles, like Mahindra XUV700, Hyundai Creta, Tata Safari, Kia Seltos and others.
The 22 ADAS Level 2 Features
1. ACC – Adaptive Cruise Control with Stop & Go
Adaptive Cruise Control, or ACC, is an advanced driving feature that helps you maintain a safe and comfortable driving experience. Normal cruise control keeps your car at a fixed speed. Unlike normal cruise control, ACC automatically adjusts your speed based on the vehicle in front of you.
When you set a speed on highways, the system uses sensors and radar to watch the traffic ahead. If the car in front slows down, your car will automatically reduce its speed. If that car picks up speed or moves away, your car will speed up again to the set level.
The “Stop & Go” function is especially useful in Indian city traffic or during highway jams. It can bring your car to a complete stop when the traffic stops. The car starts moving again when the flow restarts, without you pressing the accelerator or brake repeatedly.
This feature reduces driver fatigue. It improves comfort and ensures safe distance maintenance between vehicles. This makes long drives or bumper-to-bumper traffic much easier.
2. TSR – Traffic Sign Recognition
Traffic Sign Recognition (TSR) is an advanced driver assistance feature. It helps the driver stay aware of road signs while driving. The system uses a front-facing camera usually placed on the windshield. It detects and reads traffic signs such as speed limits, No Entry, Stop or other warnings. Once a sign is recognised, it is shown on the vehicle’s dashboard or instrument display.
For example, if you are driving and you accidentally miss a speed limit sign, the TSR system will identify it. It will then alert you by showing it on the screen. This helps you maintain the correct speed and follow road rules properly. It improves driving safety by reducing the chances of getting a traffic fine or missing important road warnings.
3. ISA (TSR) – Intelligent Speed Assist with Traffic Sign
Intelligent Speed Assist or ISA is a driver assistance system that helps you maintain the correct speed on the road. It works together with Traffic Sign Recognition (TSR) technology. This technology detects speed limit signs placed along the road. It uses a front-facing camera or sensors for detection.
The system identifies a speed limit sign. For example, it reads 60 km/h. It then quickly compares the sign with your current driving speed. If your car is going faster than the allowed limit, the system warns you with a visual or audio alert. In some advanced vehicles, the ISA system can automatically adjust the car’s speed to match the limit.
This feature is very useful in preventing speeding, avoiding traffic fines and improving overall road safety. It also reduces driver stress, especially in new or unfamiliar areas where speed limits change often.
Main functions include:
- Helping the driver follow traffic rules safely and easily
- Detecting speed limit signs using the camera and TSR system
- Warning the driver when overspeeding
- Automatically adjusting vehicle speed (in active ISA systems)
4. ISA (Map) – Intelligent Speed Assist with Map
Intelligent Speed Assist (ISA) with Map is a driver assistance system that helps control the vehicle’s speed using map-based information. It reads the road speed limits from digital maps and automatically adjusts the vehicle’s speed to match the allowed limit.
The system gently slows down the car. This occurs if the map shows that the upcoming road has a 40 km/h speed limit. For example, it adjusts the speed to stay within that limit. This helps drivers avoid speeding, follow local traffic rules, and ensure safer driving on all roads.
The ISA system can work together with cameras and sensors to check speed signs and compare them with map data. If both show a lower speed limit ahead, it automatically advises or limits the driver from going above that speed.
It is a very useful feature. This is especially true in cities and school zones where speed limits change frequently. It helps drivers stay aware and safe.
5. LCS – Lane Centering System
Lane Centering System (LCS) is an advanced driver assistance feature. It helps the car stay perfectly in the middle of its lane. It uses front-facing cameras and sensors to continuously monitor the lane markings on the road. The system detects when the vehicle is drifting toward one side. It gently adjusts the steering to bring it back to the centre.
This feature is very useful during long highway drives, where drivers can sometimes lose focus or get tired. LCS keeps the car properly centred. This reduces the need for constant small steering corrections. It makes driving more comfortable and safer.
6. ASA – Adaptive Steering Assist with ACC
Adaptive Steering Assist (ASA) with Adaptive Cruise Control (ACC) is an advanced driver assistance feature. It helps the driver keep the car steady. It also keeps the car centered within its lane.
When you turn on Adaptive Cruise Control (ACC), the system takes over speed control. It maintains a safe distance from the vehicle ahead. Adaptive Steering Assist (ASA) also adjusts the steering angle. It takes into account the road conditions, lane markings, and vehicle movement.
Together, they make driving smoother and more relaxed. The car can slightly turn the steering to stay in the lane, especially on highways or long routes. It reduces the driver’s effort and improves safety during continuous driving.
Main points:
- Adjusts steering automatically as per road lanes.
- Works with cruise control to maintain speed and distance.
- Helps the vehicle stay in the center of the lane.
- Makes highway driving safer and more comfortable.
Example:
If you are driving with cruise control set at 80 km/h on a highway, ASA ensures lane maintenance. The car stays properly in the lane. It handles mild curves without requiring frequent steering corrections by the driver.
7. LDW – Lane Departure Warning
Lane Departure Warning (LDW) is a safety feature in modern cars. It helps the driver by providing a warning. The alert occurs if the car exits its lane on the road without using the indicator.
Your car might slowly move towards the left side if you are driving and become a little sleepy. It can also happen if you are distracted. It could also move to the right side. This movement results in crossing the lane marking. If you do not turn on the indicator, the LDW system will notice this. It will quickly give you a warning. This warning is usually with a loud sound. It may also be a light on the dashboard, or even a gentle vibration in the steering wheel. This signal tells you to bring your car back into the lane safely.
Lane Departure Warning is very useful on highways. You often drive for a long time on highways and can become tired. It helps to prevent accidents by alerting you before your car moves out of the lane by mistake. This system works with the help of special cameras or sensors placed in the front part of the car. They keep a watch on the painted lines on the road.
8. LKA – Lane Keep Assist
Lane Keep Assist is a smart driving feature that helps the driver stay safely within the lane on the road. It uses a camera, usually placed near the rear-view mirror, to monitor the lane markings.
The system detects when the car is slowly drifting out of the lane without an indicator signal. It then gives a gentle steering input. This input brings the car back to the centre of the lane. The correction is smooth and light, so the driver still feels in full control.
This feature is very useful on highways or during long drives. A driver may lose focus for a short time. It helps reduce the chances of accidents caused by lane departure and makes driving safer and more comfortable.
9. FCW – Ped: Forward Collision Warning (Pedestrian)
FCW – Ped stands for Forward Collision Warning for Pedestrians. This system helps drivers by looking for people who are walking in front of the vehicle. When the car’s sensors spot a pedestrian ahead, FCW – Ped quickly gives a warning to the driver. Usually, this alert comes as a sound, a light on the dashboard or a vibration on the steering wheel. The main goal is to inform the driver as soon as possible. This allows them to slow down or stop in time. The intention is to avoid hitting the person.
This feature is very helpful in city driving, crowded roads, or near schools, where people may suddenly cross the street. FCW – Ped alerts the driver before a crash happens. It reduces the chances of accidents with pedestrians. This makes driving safer for everyone.
10. FCW – Car: Forward Collision Warning (Car)
Forward Collision Warning is a safety feature in a car that helps prevent accidents. Sensors or cameras are placed in the front of the vehicle. They detect if another car is moving or stopped ahead.
If your car is getting too close to the vehicle in front, the system gives a warning sound. The dashboard shows a visual alert if you are moving at a high speed. This speed could cause a crash. This early alert helps the driver react in time. Drivers can slow down or apply the brakes to avoid a collision.
11. FCW – Cyl: Forward Collision Warning (Cyclist)
Forward Collision Warning for Cyclists is a safety feature in vehicles. It helps in avoiding accidents with cyclists on the road. The system uses sensors and cameras to keep an eye on the road ahead. The system detects a cyclist moving in front of the vehicle. It provides a visual or audio warning. This alerts the driver.
The main purpose of this feature is to warn the driver early. This allows them to slow down or take proper action. These measures prevent a possible crash. It works especially well in city traffic or narrow roads where cyclists often ride close to vehicles.
12. AEB – Ped: Autonomous Emergency Braking (Pedestrian)
Autonomous Emergency Braking for Pedestrians (AEB – Ped) is a smart safety feature in modern cars. The car’s sensors will quickly detect a person. This happens if someone suddenly appears in front of your car while walking on the road. If the driver does not press the brake, the car will automatically apply the brakes. The same occurs if the driver does not react on time. This action will stop or slow down the vehicle.
This system is very helpful in avoiding accidents with people who are crossing the road or walking near traffic. The main aim is to prevent hitting pedestrians, especially in busy city areas. AEB – Ped provides drivers with added safety. It helps reduce the chances of injury or harm to people on the road.
13. AEB – Car: Autonomous Emergency Braking (Car)
Autonomous Emergency Braking, also called AEB, is a safety system used in modern cars. This system allows the car to automatically apply the brakes. It does so when it detects a risk of collision with another vehicle or object in front.
The car senses if a crash is likely. If the driver does not press the brake pedal in time, the AEB system quickly takes control. It applies the brakes on its own. By doing this, it either prevents the accident completely or reduces the impact speed to make the crash less severe.
AEB uses sensors such as radar, camera, or both to continuously watch the road ahead. It first warns the driver through visual or sound alerts. If the driver does not respond, the system starts braking automatically.
14. AEB – Cyl: Autonomous Emergency Braking (Cyclist)
AEB with cyclist detection enhances safety. It helps the vehicle automatically apply brakes. This happens when it detects a possible collision with a cyclist. The system uses sensors like cameras and radar to continuously monitor the road ahead. If a cyclist suddenly crosses the path or comes very close to the vehicle, the system warns the driver first. It uses visual and sound alerts to do this.
If the driver does not react in time, the AEB system automatically applies the brakes to reduce the speed. It can lessen the impact or even stop the vehicle completely to prevent a crash. This function is especially useful in city areas or narrow roads where cyclists often share the same lane with vehicles.
15. RCW – Rear Collision Warning
Rear Collision Warning is a smart safety feature that helps the driver stay alert about vehicles coming from behind. It uses sensors or radar at the back of the car. These systems detect if another vehicle is approaching too fast. They help prevent a potential rear-end collision.
If the system senses a possible collision, it gives a warning to the driver through sound, light, or vibration. This allows the driver to take the necessary action, like moving ahead or preparing to brake. This feature is especially useful in slow-moving city traffic. It is also beneficial in crowded parking areas where sudden stops happen frequently and close distances are common.
By providing an early warning, RCW helps reduce the chances of rear-end accidents and keeps both cars safe.
16. RCTA – Rear Cross Traffic Alert
Rear Cross Traffic Alert, or RCTA, is a safety feature that helps drivers while reversing their car. It uses sensors or a rear camera to detect moving vehicles, bikes, or people. They come from the sides behind your car. When something is detected, the system gives a sound or visual warning to alert the driver.
This feature is very helpful in India. It is especially useful in crowded parking areas and shopping malls. It is also beneficial in narrow lanes where visibility while reversing is very low. It reduces the chances of accidents and helps the driver reverse more safely without stress. In simple words, RCTA acts like your extra pair of eyes at the rear. It keeps you aware of cross traffic whenever you take your car out in reverse.
17. BSD – Blind Spot Detection
Blind Spot Detection (BSD) is a safety feature that helps the driver while changing lanes or driving in heavy traffic. Every car has certain areas around it that the driver cannot see directly through mirrors. These areas are called blind spots. Vehicles or bikes coming from behind in these areas are often not visible. This invisibility can lead to accidents if the driver tries to change lanes suddenly.
The BSD system uses sensors to monitor these blind spots continuously. These sensors are usually fitted on the sides or rear bumper of the vehicle. If another vehicle enters the blind spot area, the system gives a warning to the driver. This warning can appear in different ways depending on the car model. You might see a light indicator on the side mirror. It could also be a sound alert, or even a vibration on the steering wheel.
18. HBA – High Beam Assist
High Beam Assist (HBA) is a smart safety feature that helps drivers during night driving. It automatically changes the headlight beam between high and low modes based on road conditions and oncoming traffic.
When you drive on a dark road, the system turns on the high beam to give better visibility. It detects another vehicle coming from the opposite direction. Or it detects a vehicle in front of you. When this happens, it quickly switches to the low beam. This helps prevent glare and avoids disturbing other drivers on the road.
For example, HBA is very useful while driving on dark village or highway roads where there are no streetlights. You get clear visibility without manually changing the beam every time another vehicle passes by.
19. LCA – Lane Change Alert
Lane Change Alert is a safety feature that helps the driver while changing lanes on highways or busy roads. It uses sensors, usually placed on the sides and rear of the vehicle, to monitor traffic coming from behind.
If another vehicle is approaching quickly from the next lane, the system gives a warning to the driver. It uses visual or sound alerts. This helps the driver to avoid side collisions or unsafe lane change attempts.
20. OSA – Over Speed Alert
The Over Speed Alert system reminds the driver when the car exceeds the safe or allowed speed limit. It helps the driver maintain safe driving speed and avoid accidents.
When the vehicle crosses the preset speed limit, the system gives a sound warning or visual alert on the dashboard. This makes the driver slow down immediately and drive safely.
The main purpose of the Over Speed Alert is to improve road safety. It helps reduce over-speeding cases. This system protects the passengers and others on the road. Many modern cars in India now come with this feature as part of their safety system.
21. DOA – Door Open Alert
The Door Open Alert system is a useful safety feature in modern vehicles. It gives a warning when a passenger tries to open the door. This happens if another vehicle, motorcycle, or cyclist is coming from behind. This system works using sensors and cameras that detect moving objects near the car doors.
If the system senses danger, it displays a visual warning on the dashboard or side mirror. It may also give a sound alert. This helps prevent accidents that can happen when someone suddenly opens the door on a busy road.
22. BSM – Blind Spot View Monitor
Blind Spot View Monitor is an advanced safety feature found in modern vehicles. It helps the driver see areas that are not easily visible through mirrors, known as blind spots.
The driver turns on the indicator to change lanes or overtake another vehicle. At this moment, cameras placed on the sides of the car start recording live video. This video is shown directly on the dashboard screen, usually on the driver’s display or infotainment screen.
Through this system, the driver can clearly see if any vehicle, motorcycle, or bicycle is in the blind spot area. This helps in avoiding side collisions or unsafe lane changing.
The Blind Spot View Monitor gives a live view of hidden areas. It increases confidence while overtaking. This makes driving much safer, especially on highways or crowded city roads.
How Does ADAS Level 2 Work?
Mostly, it uses cameras and radar. These “eyes” are placed in front, sides, and back of the car. They keep watching the road, vehicles, pedestrians, traffic signs, and lane markings. This information goes to a smart computer, which reacts by warning you, nudging steering, applying brakes, or changing headlight beams. The driver still remains in control and must stay alert.
Example – Mahindra XUV700
Mahindra XUV700 comes with ADAS Level 2 features like Adaptive Cruise Control, Lane Keep Assist, AEB, and Traffic Sign Recognition. Suppose Rohit is taking his XUV700 from Mumbai to Pune. On highway, ACC maintains a safe distance. Lane Keep Assist ensures he does not drift. AEB is prepared in case anybody stops suddenly in front. These features make the long journey less tiring and much safer.
