What does autonomous emergency braking mean?
2 Answers
Autonomous emergency braking refers to a technology where the vehicle can actively generate braking effect to decelerate when encountering sudden hazardous situations during normal driving (without adaptive cruise control), thereby improving driving safety. The active safety system refers to a safety system including ABS and ESP electronic devices. When the preceding vehicle brakes, stops, or encounters other obstacles, the system automatically increases braking force to help the driver shorten the braking distance before taking action. The function of braking is to reduce speed or bring the vehicle to a stop. Its working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between brake pads and brake drums, as well as between tires and the ground, thereby decelerating or stopping the car.
Automatic emergency braking (AEB) is a vehicle safety technology that automatically detects obstacles ahead and applies the brakes to prevent collisions while driving. Having used several cars equipped with this feature, I find it greatly assists in daily driving. For instance, in urban traffic congestion, if I follow too closely or get distracted, the car will automatically slow down or even stop to prevent rear-end collisions, significantly reducing driving stress. However, it's not a magical solution—heavy rain or thick fog can impair radar functionality, so I always maintain a safe distance and stay alert to road conditions. This technology is beneficial for both novice and experienced drivers, as it compensates for delayed reactions in critical moments, but it should never be fully relied upon—safety awareness remains paramount. Overall, AEB is an excellent feature for enhancing driving protection and is worth considering when choosing a car model equipped with it.
