摘要： A method is provided for controlling a drivetrain of a vehicle, wherein the drivetrain comprises a multi-clutch transmission. The gear shift of the multi-clutch transmission is adapted to be performed either by power cut shift or by power shift dependent on predetermined vehicle shift conditions. The method includes detecting at least one of a plurality of indications of slippery road conditions and setting a slip risk factor, wherein the slip risk factor is dependent on the indication of slippery road conditions. If the slip risk factor is above a first predetermined threshold value the method further comprises controlling the multi-clutch transmission such that an upcoming gear shift is performed as a power-shift independently of if upcoming shift was determined to be performed as a power-cut shift or as a power shift.

摘要： A coupling device (K) has a first positive-locking clutch (K0), a second positive-locking clutch (K1), an axially fixed first shaft (W1), an axially fixed second shaft (W2), a connecting shaft (WV) and an actuator (AK). The first shaft (W1), the second shaft (W2) and the connecting shaft (WV) are arranged coaxially to each other. By closing the first clutch (K0), a torque-proof connection between the first shaft (W1) and the connecting shaft (WV) is established, and by closing the second clutch (K1), a torque-proof connection between the connecting shaft (WV) and the second shaft (W2) is established. The actuator through axial displacement of the connecting shaft (WV), shifts both the first clutch (K0) and the second clutch (K1) between an engaged state and a disengaged state, such that the connecting shaft (WV) is movable to a multitude of axial positions to achieve different engaged states of the clutches.

摘要： A twin clutch controlling apparatus wherein an interposition of a manual operation into an automatic control clutch can be executed smoothly. The twin clutch controlling apparatus includes an AMT controlling unit for controlling a shift actuator and a clutch actuator, and a shift pedal P for carrying out a shifting request to the AMT controlling unit. If, after driving of the shift actuator is started in response to the shifting request by the shift pedal, a clutch lever is operated in a connection direction before a next stage gear is placed into an in-gear state, then the controlling section drives one of an odd number stage side clutch and an even number stage side clutch which corresponds to the gear before the shifting in a corresponding relationship to a manual operation clutch capacity arithmetic operation value.

摘要： A clutch device includes an input rotor, a first clutch, a second clutch, a first drive mechanism and a second drive mechanism. A first clutch is disposed switchably between a first transmitting state of transmitting power and a first blocking state of blocking power transmission. A second clutch is disposed switchably between a second transmitting state of transmitting power and a second blocking state of blocking power transmission. The first drive mechanism includes a first drive support member and the second drive mechanism includes a second drive support member. A drive clearance is configured to be produced axially between the first drive support member and the second drive support member in the first blocking state and the second blocking state. The drive clearance is less than a sum of the first stroke and the second stroke.
