About Advanced Emergency Braking System (AEBS):
- AEBS is an active vehicle safety technology designed to prevent collisions or reduce their severity.
- It is a combination of braking and sensor technology integrated into automobiles to recognise and prevent crashes.
- The system continuously monitors the road ahead, warns the driver when it detects a potential collision with another vehicle, pedestrian, or cyclist, and automatically applies the brakes if the driver fails to respond in time.
- AEBS is a key feature of Advanced Driver Assistance Systems (ADAS), a collection of more than 100 electronic technologies designed to improve road safety.
- How does AEBS work?
- AEBS operates continuously while a vehicle is moving.
- It uses a combination of radar sensors, cameras, or Light Detection and Ranging (LiDAR) technology, typically mounted near the front bumper or windscreen, to assess the distance from obstacles, their relative speed, and the time remaining before a potential collision.
- The system generally works in three stages:
- Warning stage: When the system detects an obstacle approaching rapidly and calculates that a collision is imminent, it issues an audio-visual alert, such as a dashboard warning light and a beeping sound, prompting the driver to brake.
- Partial or pre-braking stage: If the driver does not respond, the system may apply a brief, sharp brake pulse as a warning and pre-charge the braking system to maximise stopping power.
- Full emergency braking stage: If the driver still fails to take action and a collision is imminent, AEBS automatically applies maximum braking force.
- AEBS can reduce the impact of various crashes, including head-on, rear-end, right-turn, and pedestrian collisions.
