DOPPELKUPPLUNGSGETRIEBE

A dual clutch transmission includes a first and second input shaft (21, 22), an output shaft (23), a dual clutch (24) having a first clutch (25) and a second clutch (26), a first and second gear transmission mechanisms (30A, 30B), and a control device (50) connected to an accelerator opening degree sensor (51), detecting an accelerator opening degree (O), and a rotational speed sensor (52), detecting a rotational speed (R) of an engine (11), and is provided with a pra-shift control device pre-selecting the shift stage gear set (31a and 31b, 32a and 32b, 33a and 33b, 34a and 34b, 35a and 35b, 36a and 36b) for establishing the shift stage, which: is one stage upper or lower than the shift stage established by the selected shift stage gear set 31a and 31b, 32a and 32b, 33a and 33b, 34a and 34b, 35a and 35b, 36a and 36b), from one of the first and second gear transmission mechanisms (30A, 30B), when values of the accelerator opening degree (O), the rotational speed (R), and the rotation acceleration (A), becomes equal to or more than predetermined upper shift stage pre-shift setting values (Oa, Ra, Aa) or equal to or less than predetermined lower shift stage pre-shift setting values (Ob, Rb, Ab).
