These sensors not only identify obstacles around the vehicle but also sense the distance between the vehicle and the obstacle, as well as vehicle speed. When the system determines a collision risk, it automatically controls the vehicle to apply emergency braking, thereby avoiding or mitigating the occurrence of a collision.

The first millimeter-wave radar is installed on the middle part of the front side of the automobile, and the second millimeter-wave radar is installed on the middle part of the right side of the automobile. The automatic emergency braking system for automobile blind spots utilizes two millimeter-wave radars to collect and analyze the driving environment of the blind spot of the automobile on the right side of the vehicle.
