The invention discloses an activation method for associating engine braking and a whole vehicle hydraulic retarder. The activation method comprises the following steps that S1, an engine rotating speed overspeed calibration value is calibrated; s2, acquiring an engine running state by using a controller, comparing the engine rotating speed with the overspeed calibration value, and determining that the engine rotating speed is greater than the overspeed calibration value; and S3, executing the strategy I and/or the strategy II according to the rotating speed of the engine. The method has the advantages of simple control, improved driving safety and the like.
