[0002] When the Automatic Emergency Braking System (AEBS) detects a possible collision risk in front of the vehicle, it will issue a warning to the driver through sound, image, vibration seat, vibration steering wheel, etc., to remind the driver to take measures to avoid or reduce the collision; as the degree of danger increases, if the driver does not respond correctly to the warning signal in time, the system will start to automatically brake with a certain braking force, reducing the speed and reminding the driver; when the collision risk becomes very urgent, the system will automatically apply full braking to avoid a collision or reduce collision damage.
