20110190990 | SHIFT CHANGE CONTROLLING APPARATUS - The twin clutch-type transmission can include a hydraulic twin clutch including the first clutch and the second clutch disposed on main shafts. The shift change controlling apparatus is configured to control shift change operation to and adjacent speed change stage by alternately changing an engagement state of the first clutch and the second clutch. The shift change controlling apparatus can also execute a pre-shift change of supplying a pre-pressure on one of the first and second clutches, while another of the first and second clutches is engaged. The pre-pressure provides a pre-engagement of the unengaged clutch. First and second clutch actuators are configured to actuate the first and second clutches, respectively. When the pre-shift change is executed, the pre-pressure is applied for a predetermined period and then removed prior to a driving of a shift gear or actuating a shift change. | 08-04-2011 |
20110190996 | CLUTCH CONTROLLING APPARATUS - A clutch controlling apparatus includes a shift change transmission having a plurality of gear trains between a main shaft on an input side and a countershaft on an output side. A clutch controls transmission of power between the shift change transmission and an engine between engagement an disengagement. The clutch controlling apparatus automatically controls the clutch upon shift change of the shift change transmission. An input power ratio is calculated as a ratio between a rotation of the engine and a rotation of the countershaft. If the input/output power ratio exceeds a predetermined value in a direction of a rise of the rotation of the engine during shift change of the shift change transmission, a target control amount of the clutch is corrected in a clutch engagement direction. | 08-04-2011 |

Thus, the position of the clutch connection/disconnection member (i.e. a stroke amount of the elastic member) and a torque transmission capacity of the clutch device have a linear relationship with each other. Hence, the torque transmission capacity of the clutch device can be accurately controlled by the electric actuator. | 12-08-2011 |

20140095033 | TWIN CLUTCH CONTROLLING APPARATUS - A twin clutch controlling apparatus includes an ATM control unit for controlling a shift actuator and a clutch actuator and a shift pedal P for carrying out shifting request to the ATM control unit. When a shifting request by the shift pedal P is issued, the ATM control unit drives the shift actuator to change over the shift stage to a next stage gear irrespective of an operational amount of a clutch lever L and then causes the manual operation clutch capacity arithmetic operation value (tqcltmt) to correspond to a clutch capacity corresponding to the next stage gear using an operational amount of the clutch lever L that exceeds a predetermined value as a trigger. If a predetermined period of time elapses while the clutch lever L is not operated, then the shifting request is an erroneous operation and the shift stage is returned to an original gear. | 04-03-2014 |
