The invention provides an automatic emergency braking method and an automatic emergency braking device. The method comprises the steps that a corresponding relationship of road adhesion coefficient and target deceleration is set, and the target deceleration obtained through the corresponding relationship can avoid the intervention of a deadlock prevention braking system under the condition of the road adhesion coefficient; the current road adhesion coefficient is obtained via the deadlock prevention braking system; the corresponding relationship is searched according to the current road adhesion coefficient, so that the current target deceleration is obtained; the collision time is calculated according to the speed of the vehicle, the speed of a front vehicle, the distance between the two vehicles and the current target deceleration; when the collision time is less than a threshold value, the automatic emergency braking is carried out according to the current target deceleration. The automatic emergency braking method and the automatic emergency braking device aim to ensure the performance of the automatic emergency braking system and prevent the occurrence of collision accidents when the vehicle runs under lower road adhesion coefficient.
