Claims (1)

[Scope of utility model registration request] A first counter shaft having a plurality of first speed change spur gears for odd speeds, a second counter shaft having a plurality of second speed change spur gears for even speeds, and a rotation of an input shaft. first and second counter shaft selection clutches for selectively transmitting power to each of the counter shafts, and a plurality of clutches each disposed on each of the counter shafts to selectively transmit rotational force of each of the transmission spur gears. This is a control device for a multi-stage transmission with a compound clutch, which has a first gear selection clutch and a second gear selection clutch for transmitting a signal to an output shaft. a select position detection sensor that detects the select position of the gear shift lever; a low speed determination means that determines that the vehicle speed is below a predetermined value based on a detection signal from the vehicle speed sensor; an accelerator fully closed determining means for determining that the accelerator opening is almost fully closed based on a detection signal from the sensor; and determining that a position other than neutral or parking is selected based on a detection signal from the select position detection sensor. Signals from the select position determining means, the low speed determining means, the fully closed accelerator determining means, and the select position determining means indicate that the vehicle speed is below a predetermined value, the accelerator opening is almost fully closed, and the position is other than neutral or parking. and half-clutch signal output means for outputting a half-clutch signal for maintaining one of the first and second counter shaft selection clutches in a half-clutch state when the clutch is selected. A control device for a multi-speed transmission with a complex clutch.
