What does AEB mean in cars?

[AnthonyDella]

AEB stands for Autonomous Emergency Braking, which is translated as automatic braking system in Chinese. It is an active vehicle safety technology that can automatically monitor the distance and relative speed of objects ahead. When the driver brakes too late, with insufficient braking force, or fails to brake, the vehicle will issue a warning or initiate autonomous braking. Process of Autonomous Emergency Braking (AEB): If the driver does not respond to the Forward Collision Warning (FCW) and the danger level continues to escalate, the system will request the powertrain to reduce torque and the braking system to perform emergency braking. Active torque reduction: in dangerous situations, the system can request the powertrain to reduce torque. Emergency braking: depending on the target identified by the sensors and the danger level, the system can apply different levels of autonomous braking. Classification of Autonomous Emergency Braking: Partial Autonomous Emergency Braking (Standard) (AEB-Pstandard) Standard partial autonomous emergency braking triggers early (simultaneously with the emergency warning), primarily to give the driver more reaction time. If the driver does not respond, it will also reduce the danger level of the accident. This function is used for moving and stationary targets, with a deceleration range of (-1.5~-3.5) m/s², and can reduce the vehicle speed by up to 40 km/h. Partial Autonomous Emergency Braking (Enhanced) (AEB-Pextended) When the driver does not respond to the standard partial autonomous emergency braking or the situation is already very urgent, the system will activate partial emergency braking with higher deceleration to avoid an accident or reduce its severity. This function is used for moving and stationary targets, with a deceleration range of (-1.5~-6) m/s², and can reduce the vehicle speed by up to 40 km/h. Medium-speed Autonomous Emergency Braking (AEB-M) Used for moving and stationary targets. This function activates at medium speeds. When the system calculates that a large, uncomfortable deceleration is necessary to avoid a collision, it will trigger this function to perform automatic braking to minimize the relative speed between the two vehicles as much as possible. This function is used for moving and stationary targets, with a deceleration range of (-1.5~-8) m/s², and can reduce the vehicle speed by up to 40 km/h. High-speed Autonomous Emergency Braking This function is used for emergency braking when the sensors detect pedestrians, with higher priority than AEB-M. The maximum deceleration is -9 m/s², and it can reduce the vehicle speed by up to 24 km/h.
