摘要： The deterioration of comfort is prevented by suppressing the shifting of a timing for releasing a claw clutch due to a change in the characteristic of a friction clutch or the like at the time of torque transmission switching from the claw clutch to the friction clutch during speed changing. A start timing for releasing the claw clutch is learned by determining a state of the released claw clutch. Even when a characteristic change occurs because of a change with time, such as the response delay of an assist clutch or the like, each optimal releasing control timing is learned.

摘要： A large gearshift shock that occurs if a renewed gearshift operation is forcibly carried out in order to meet a new gearshift request made through a driver's operating an accelerator pedal or a signal from an operation lever during a current gearshift operation. Gearshift response lag occurs due to an attempt to avoid the large gearshift shock. To solve these problems, a control system for a gear type transmission is mounted. The control system is provided with a renewed gearshift disabling period, during which any renewed gearshift request to a third predetermined gearshift position made during a gearshift operation from a first predetermined gearshift position to a second predetermined gearshift position is disabled.

摘要： A mesh type automatic transmission is equipped with a plurality of shift gears arranged to rotate freely to an output shaft for providing driving force to the wheels. Cogged clutches 12, 15 engage with the output shaft. Counter shift gears corresponding to each speed are fixed to a counter shaft rotated by the rotation of an input shaft and mesh with the shift gears for performing automatic shifting by controlling engagement of one of the cogged clutches with the voluntary shift gears determined from the accelerator command value and the vehicle speed. An assist mechanism transmits rotational force of the input shaft to the output shaft via the assist shaft which rotates from the rotation of the counter shaft when no cogged clutch of the plurality of cogged clutches is engaged with any of the plurality of shift gears occurring during switching when an engaged cogged clutch of the plurality of cogged clutches is disengaged and one of the cogged clutch of the plurality of cogged clutches is to be engaged.
