Control apparatus of vehicular automated manual transmission

May 15, 2002
A control apparatus (41) of a vehicular automated manual transmission includes an input shaft (4) provided with a plurality of drive gears (11 - 15), and an output shaft (5) provided with a plurality of driven gears (21 - 25) engaging with the drive gears (11 - 15), in which the drive gears (11 - 15) and the driven gears (21 - 25) form a plurality of transmission gear trains through engaging with each other. When down-shifting among the transmission gear trains, an engine speed (Ne) is set higher by a predetermined value ( alpha ) than an input shaft rotational speed (Nm). Thereby, the drag torque of the wet clutch (6) works in such a manner that the input shaft rotational speed (Nm) is increased, so that the difference of rotational speed between the input shaft (4) and the output shaft (5) becomes small. Accordingly, a transmission characteristic of the vehicular automated manual transmission with a wet multi-disc type clutch (6) can be improved.
