The invention relates to the technical field of automobile driving safety, in particular to a road surface type recognition method and a vehicle autonomous emergency braking control method and device based on the road surface type recognition method, and the method comprises the steps: obtaining the current state information of a vehicle and the current state of a target in front of the vehicle through a vehicle camera and a sensor, and transmitting the obtained information to an automobile domain controller; point cloud reflection intensity characteristics are obtained by means of a laser radar to identify the road surface type in front of the vehicle, so that the road surface adhesion coefficient is obtained; whether potential risks exist or not is judged by conducting danger assessment on the driving state of an automobile in the transverse direction and the longitudinal direction, and braking measures are taken according to the response of a driver. The vehicle driving road surface type is recognized in advance, so that the accuracy of estimating the road surface adhesion coefficient is improved; the real-time change of the state of the front road surface is fully considered, braking is dynamically adapted and adjusted, vehicle braking can be gently achieved, and road driving and vehicle active safety are effectively improved.
