To provide a shift change controlling apparatus which solves the subject of the prior art described above and can prevent occurrence of hammering relating to the other side clutch during traveling with one side clutch and prevent also occurrence of hammering upon pre-shift change. In a shift change controlling apparatus for a twin clutch type transmission 23 which includes a hydraulic twin clutch 26 and allows a shift change operation to an adjacent shift change stage by alternately changing over an engagement state of two clutches and besides executes pre-shift change of supplying, during ordinary traveling with the clutch on one side engaged, a pre-pressure for operating the clutch on the other side by a small amount toward the engagement side and creating in advance a state in which power transmission using a shift gear train corresponding to a next shift position can be carried out, when the pre-shift change is executed, within a period after a signal for driving clutch actuators 91a and 91b for supplying a pre-pressure in a direction in which the pre-pressure is removed is issued until driving of the shift gear as the pre-shift change is started, predetermined pre-shift change waiting time at least corresponding to a speed of rotation of the main shafts 43, 44 is provided. |
