Driving in India can be challenging with heavy traffic, unpredictable pedestrians and sudden obstacles on the road. Even the most careful drivers can face situations where a split second makes all the difference. Autonomous Emergency Braking or AEB, is a safety feature that detects potential collisions and automatically applies brakes to reduce the risk of or damage from an accident.

Understanding how AEB works, its benefits and limitations and which cars in India offer it can help you make smarter choices for safer driving; and ensure your car insurance policy covers such advanced safety features.

What is Autonomous Emergency Braking (AEB)?

Autonomous Emergency Braking is a safety feature that automatically applies the brakes if the system detects a potential collision. It utilises sensors, cameras or radar to monitor the road, helping to reduce the severity of accidents or avoid them entirely.

AEB is also included in modern vehicle safety ratings and is becoming a global standard for road safety.

How does Autonomous Emergency Braking work?

Car AEB continuously scans the road using sensors, cameras or radar to detect vehicles, pedestrians or obstacles. If it senses a potential collision and the driver does not react in time, the system automatically applies the brakes.

The braking force is adjusted based on the vehicle’s speed and the distance to the obstacle to reduce impact or prevent the crash.

What are the different types of Autonomous Emergency Braking?

Autonomous Emergency Braking system comes in several types depending on driving conditions. City AEB works at low speeds and is useful in heavy traffic. Highway AEB operates at higher speeds to reduce the impact of fast-moving collisions.

Pedestrian and cyclist detection identifies and responds to vulnerable road users. Cross traffic AEB helps detect risks when reversing or crossing intersections.

What are the pros and cons of Autonomous Emergency Braking (AEB)?

Autonomous Brake system offers several benefits. It helps reduce rear-end collisions, enhances driver confidence in heavy traffic and contributes to higher vehicle safety ratings. At the same time, it has some limitations.

The system may not always detect small or suddenly appearing obstacles; its effectiveness can decrease in poor weather or low visibility and repairs or replacements for sensors can be expensive.

Can Autonomous Emergency Braking (AEB) be installed from the aftermarket?

AEB generally cannot be added as an aftermarket feature because it requires integration with factory-fitted sensors, cameras and the braking system. Aftermarket kits may not meet manufacturer safety standards; therefore, the most reliable way to obtain AEB is to purchase a vehicle that comes equipped with it from the factory.

Affordable cars in India that offer Autonomous Emergency Braking (AEB)?

AEB is no longer limited to premium models and is gradually appearing in more affordable cars in India. Brands such as Honda, MG and Hyundai are offering AEB in mid-range SUVs and sedans.

As EVs and hybrids become more common, AEB is expected to become a standard feature, with pricing gradually becoming more competitive across different models.

Conclusion

Autonomous Emergency Braking is more than a feature; it is a practical tool that can help prevent accidents and keep you safer on Indian roads. While cost and certain limitations exist, the benefits of AEB in reducing collisions and enhancing driver confidence are significant. When combined with comprehensive car insurance, which helps protect your vehicle and financial security, AEB can play a key role in making everyday driving safer and more reassuring.
