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 speed detection sensor, a shift map storage means for storing a shift map, an optimal gear stage determination means for determining an optimal gear stage based on signals from the vehicle speed sensor, the accelerator opening degree detection sensor, and the shift map storage means;
Current gear stage determination means for determining the current gear stage;
two-speed shift determining means for determining that a two-speed shift is necessary based on signals from the optimum gear determining means and the current gear determining means; the optimum gear determining means, the current gear determining means, and the two-speed shift; and a control signal output means for outputting a control signal for controlling each of the counter shaft selection clutches and each gear selection clutch according to the signal from the determination means, and the two-stage shift determination means determines whether the two-stage shift is possible. When it is determined that it is necessary, the half-clutch state is maintained at the intermediate gear between the optimum gear and the current gear, and the clutch for selecting the counter shaft on the optimum gear is disengaged, so that the optimum gear is selected. The speed change spur gear and the counter shaft are connected by a gear selection clutch,
After that, the counter shaft selection clutch on the intermediate gear side is disengaged, and the counter shaft selection clutch on the optimum gear side is brought into the engaged state. Control device.
