Patent ID: 7497804

Claim:
An automatic gearshift control device comprising: a friction clutch provided between a driving side power transmission mechanism and a driven side power transmission mechanism; a transmission; an automatic gearshift device including an electrically-driven actuator configured to control engagement of the friction clutch and for shifting gears of the transmission; a reduction rate obtaining device configured to obtain a reduction rate of a difference in clutch rotational number defined on the basis of a difference between the driving side rotational number and the driven side rotational number, the driving side rotational number being a rotational number of a driving side part of the friction clutch or the driving side power transmission mechanism and the driven side rotational number being a rotational number of a driven side part of the friction clutch or the driven side power transmission mechanism; a connecting speed setting device configured to set a speed for connecting the friction clutch so that the reduction rate of the difference in clutch rotational number, the reduction rate being obtained by means of the reduction rate obtaining device, would reach a predetermined target value; and a control device configured to control drive of the actuator so as to connect the friction clutch at the connection speed set with the connecting speed setting device.
