The Automatic Emergency Brake (AEB) function of a vehicle is a feature of the Forward Collision Warning System (FCWS). It is a safety function detected and triggered by a superior controller (such as IFC or MCS). When the superior controller (such as IFC or MCS) identifies that the vehicle is in an emergency situation and the driver does not apply the brake accordingly, the AEB function is triggered. It is executed by the ESC module, and the vehicle automatically applies the braking action to reduce the risk of a collision.
System function architecture
In the same driving cycle, the time interval between two braking requests of the AEB control system is greater than 20 seconds. In the same driving cycle, the minimum time interval for the ESC to respond to two braking requests from the AEB control system is 20 seconds. seconds.
When the AEB function is available, the functional states are divided into Off, IB, and BA.
AEB testing equipment
China Automotive Technology and Research Center’s AEB Test and Evaluation Method
To evaluate the AEB, the full score is 13 points. The actual score obtained is proportionally converted to a full score of 10 points, rounded to one decimal place to get the final total score.
