Cars to brake on their own: Centre plans AEBS mandate from Oct 2030

An advanced emergency braking system, or AEBS, is a safety feature that watches for an imminent collision with a vehicle or obstacle. It matters because it can act when a driver reacts too slowly or fails to react. The system is designed to prevent crashes or reduce their severity.

For example, if a car approaches another vehicle dangerously, AEBS detects the threat. If the driver does not respond adequately, it automatically applies the brakes. The braking action is the system’s direct intervention, rather than merely a warning. AEBS is described in the article as the most important ADAS feature.

The system is already present in some cars, but its use is being expanded through proposed government rules. New car models would need AEBS from October 2030. Models introduced before 2030 but still in production would need it from October 2032. New truck and bus models face an earlier deadline, starting January 2027.

AEBS requirements will cover several vehicle groups, with different deadlines. New truck and bus models must have the system from January 2027. For cars, the proposed rule would apply to every new car model from October 2030. The government is giving industry time to prepare for these changes.

A car model launched before 2030 but still being produced would have a later deadline. Those pre-2030 models would need AEBS from October 2032. The article also says the wider ADAS focus will be particularly important for taxis, although the AEBS deadlines described for cars apply to new and continuing models.

Some cars already have ADAS, but the proposed notification would establish common requirements. The timelines are intended to provide lead time for manufacturers and users. Commercial vehicles have already been assigned several related safety requirements, including AEBS, blind-spot information, moving-off information, drowsiness alerts, and lane-departure warnings.

ADAS, or Advanced Driver Assistance Systems, is a broad category of electronic safety technology. The article describes it as a set of more than 100 technologies. They share a purpose: improving safety by helping detect hazards and supporting the driver before a crash occurs.

The category includes systems that warn the driver, such as lane-departure warnings and drowsiness alerts. It also includes systems that can act automatically. AEBS may apply the brakes, while more advanced systems can intervene in steering or lane-keeping. This makes ADAS much broader than one braking system.

Some cars already have ADAS, but coverage is not yet universal. The government is preparing a draft notification with timelines for different features. The proposed rules would first establish requirements for vehicles such as cars, taxis, trucks, and buses. The goal is to expand safety assistance while giving industry and users time to prepare.

AEBS is designed to intervene at a critical moment. It detects an imminent collision involving a vehicle or obstacle, then checks whether the driver has responded adequately. If the response is insufficient, the system takes over braking. This matters because a short delay can determine whether a crash happens.

For instance, a vehicle may be closing rapidly on an obstacle while the driver fails to brake enough. AEBS automatically applies the brakes rather than waiting for further driver action. According to the article, that action can prevent a crash or reduce how severe it becomes. The system therefore supports, rather than replaces, the driver’s normal response.

AEBS is already fitted to some cars, but proposed rules would make it more widespread. New truck and bus models would need it from January 2027. New car models would need it from October 2030, while pre-2030 models remaining in production would have until October 2032.

The government’s special attention reflects the demands placed on commercial drivers. The article says these drivers can spend hours behind the wheel. Long periods of driving can make safety-critical and fatigue-inducing decisions harder, so assistance systems may offer particular value in commercial use.

Taxis are a major focus of the proposed car-related rules. Planned features for taxis include automatic command steering, emergency lane keeping, and drowsiness and attention warning systems. New trucks and buses will also receive AEBS, along with several information and warning features. These systems can support drivers when a hazard or fatigue-related risk develops.

Automobile and mobility expert Rama Pandey said ADAS could make driving safer and less strenuous for commercial drivers. He described automated systems as a way to shift more safety-critical decisions away from fatigued drivers. The proposed timelines also give commercial users and manufacturers lead time to comply with the new requirements.

The proposed and announced features address different driving risks. Blind-spot information helps with areas a driver may not easily see. Moving-off information supports safer movement from a stopped position. Lane-departure warnings address unintended drifting, while drowsiness detection and alerts address fatigue-related loss of attention.

For example, a truck or bus will be required to have blind-spot information, moving-off information, driver drowsiness detection and alert, and lane-departure warning systems. These features mainly warn or inform the driver. AEBS goes further by automatically applying the brakes when a collision is imminent and the driver does not respond adequately.

The article also says several features would be made mandatory for taxis. These include automatic command steering functionalities, an emergency lane-keeping system, and drowsiness and attention warning systems. The rules are still described as proposed in the article, with a draft notification expected soon and timelines intended to provide preparation time.

The article explains what ADAS does, but it does not specify cameras, radar, or software components. In established ADAS design, sensors collect information about nearby vehicles, obstacles, lane markings, and vehicle movement. Cameras usually interpret visual details, while radar measures objects and relative motion. Other sensors may contribute, depending on the system.

Software combines these inputs and estimates whether a hazard is developing. If the risk crosses a system threshold, it can warn the driver. In an AEBS example, the software identifies an imminent collision and checks the driver’s response. If that response is inadequate, vehicle controls apply the brakes. More advanced systems can influence steering or lane-keeping.

This sensor-to-control process explains why ADAS includes more than 100 technologies. Some only provide information or warnings, while others intervene directly. The article says some cars already have ADAS and that future rules would expand requirements for cars, taxis, trucks, and buses, with staged deadlines.
