The invention belongs to the technical field of automobiles, and particularly relates to an AEB control method based on multi-sensor road adhesion coefficient fusion. Comprising the following steps: step 1, obtaining a visual road adhesion coefficient of a vehicle; step 2, acquiring a dynamic road adhesion coefficient of the vehicle; 3, fusing the visual pavement adhesion coefficient and the dynamic pavement adhesion coefficient; 4, judging the collision time of the front dangerous target based on a safety time model; and 5, executing an emergency braking control strategy according to the judged collision time of the front dangerous target. A camera in front of a vehicle is used for obtaining a road surface image, and a visual adhesion coefficient of a road surface is extracted through an image processing algorithm; meanwhile, the dynamic road adhesion coefficient of the vehicle is obtained through a sensor of the vehicle; then, the two attachment coefficients are fused, the attachment coefficient of the vehicle can be estimated more accurately, and therefore the accuracy and robustness of the automatic emergency braking system are improved.
