Hydraulic cylinder buffering control method and device

The invention provides a hydraulic cylinder buffering control method and device, and belongs to the technical field of hydraulic cylinder buffering control. The method comprises the following steps: detecting the position of a piston rod in the process that the piston rod moves towards a terminal point, starting to control an electromagnetic reversing valve to reverse when it is judged that the distance value between the piston rod and the terminal point is equal to a set value, and completing reversing after the reversing duration, wherein the moment when the electromagnetic reversing valve is controlled to reverse is an initial moment, and the moment when the electromagnetic valve completes reversing is an ending moment; enabling the piston rod to start to decelerate from the initial moment, and reach the terminal point and stop at the ending moment; according to the volume V of hydraulic oil flowing through the electromagnetic reversing valve in the reversing process under the set pressure and the stress a
