PURPOSE:To prevent a shock in the time of shift-in operation by measuring a load current in a motor, when it performs the shift action, to be studied and controlling a current conduction to the motor of a shift actuator being based on this study value when a shift control is performed. CONSTITUTION:A control unit 5 inputs signals from a stroke sensor 14, rotary encoder 45, select sensor 51 and a clutch sensor 52, selecting a predetermined shift block in a speed change mechanism 3 by actuating a motor 41 of a select actuator 4 while performing the shift-in action to a desired speed change shift by actuating a motor 11 of a shift actuator 1. While measuring a load current in the shift action of the motor 11 to be stored in memory as a study value, a synchromesh load is set in accordance with a change of this study value when a shift control is performed, and the current in the motor 11 of the shift actuator 1 is controlled. Thus a shock in the time of shift-in operation can be prevented. |
