PURPOSE:To obtain a large degree of freedom for the control of speed change ratio, by connecting an electronic control unit with a speed change driving gear and performing a speed change control by the electronic control unit selecting any one of the acceleration, deceleration and the fixed speed in accordance with a vehicle running condition. CONSTITUTION:An electric motor in a speed change driving gear and both solenoids 1151, 1152 of a speed change auxiliary device connect an electronic control unit 151 for controlling the action of these above. This electronic control unit 151 has a detecting part 152 for detecting the running condition of a vehicle, logical control part 153 determining a speed change control condition in accordance with the detection signal of said detecting part 152 and a driving control part 154 outputting an operation signal in accordance with an output of the logical control part 153. And the speed change control condition is determined in the logical control part 153 in accordance with the detection signal of the detecting part 152, but the speed change control condition, which changes if a speed change map in said logical control part is changed to be set, enables a speed change control, based on various requirements of the driver, to be performed. |
