What is an Automatic Emergency Braking System in Cars, and Which Cars in India Have it?

Automatic emergency braking (AEB) is a safety technology that can save your life by preventing a collision automatically. If a collision is imminent and the driver does not take any action, autonomous emergency braking (AEB) systems begin braking automatically (or are not doing so fast enough). AEB can detect a probable accident and activate the braking system to decelerate the vehicle, thereby avoiding or at least lessening the effect of the collision. AEB is part of the second wave of active safety systems being installed in passenger vehicles, which include cutting-edge technology such as onboard sensors, radar, cameras, GPS, and lasers. Active safety technology can either prevent accidents from occurring or actively assist the driver in minimizing the impact of an emergency situation. In dangerous situations, active systems provide the driver additional control.

How do AEB works?

To that purpose, different safety systems constantly monitor a vehicle’s performance and surroundings. Simply, active safety systems prevent or lessen an accident before it occurs or contact is made. Sensor data fusion combines the advantages of several sensors and measurement methods in the most efficient way possible, resulting in data that individual sensors working independently are unable to create. The fusion of data from several sensors improves measurement reliability, range, and precision. The various measuring concepts are also utilized to corroborate the detection of things. To identify potentially dangerous circumstances, radar, cameras, or LiDAR are routinely used. The slower the car is driving, the more likely the automated emergency braking system will be able to bring it to a halt in time to avoid a collision. Some AEB systems can only operate at slower speeds. They are intended to prevent collisions in cities, congested areas, and parking lots. Mazda’s Smart City Brake Support, for example, might automatically brake a car going at less than 18 mph to avoid a collision or reduce speed before to impact.

How effective is AEB?

It is doubtful that self-driving cars will be widely available before 2030. However, in just a few years, we have seen the commercialization of cars with increasing degrees of partial automation. These self-driving cars can currently conduct a growing variety of driving responsibilities in specified settings, such as autonomous parking and highway pilot. Under some conditions, advanced driver assistance systems (ADAS) can already take over safety-critical activities (such as steering and braking) from the driver. In the near term, ADAS will also play a critical role in preparing drivers and other road users for the reality of automobiles taking over control from drivers as we progress toward fully autonomous vehicles. Removing the driver from the equation reduces the element of human error in driving, which is responsible for 90% of all accidents today. A self-driving car will not use a cellphone while driving, nor will it break speed limits or drive while under the influence of alcohol or narcotics.

Cars in India with AEB

In India, there are a plethora of vehicles equipped with AEB. A few high-end luxury vehicles, such as the latest generation BMW 7 series, will offer this capability. The Volvo XC40 R-Design, which incorporates Radar Assisted Semi-Autonomous Driving and costs 39.9L INR, is the cheapest automobile. This feature is still being developed by Indian mass-market car manufacturers such as Mahindra. Tata, on the other hand, has access to this technology through its ownership of Jaguar and Land Rover. Perhaps Tata will be the first to deploy this feature in our mass-market below the 15 lakh INR category. The scenario about this feature becoming mainstream in India is a little murky. At the ‘Stop the Crash’ event of the Global New Car Assessment Program in September 2018, the Ministry of Road Transport and Highways (MoRTH) stated that ESC and AEB systems will be mandated in Indian cars beginning in 2022.
