Method for adapting the clutch characteristics in a twin-clutch system

A method for adapting clutch characteristics when a vehicle is moving, said vehicle having a twin-clutch system that comprises a first branch having a first clutch and a first partial transmission mounted downstream thereof, and a second branch having a second clutch and a second partial transmission mounted downstream thereof, said first and second partial transmissions comprising at least a gear A and at least a gear B, respectively, the first and second branches operatively arranged for connection to an engine on an input side and to vehicle wheels of the vehicle on an output side, and the first clutch being operated by a first clutch actuating mechanism and the second clutch being operated by a second clutch actuating mechanism, said method comprising the steps of:

• (a) transmitting a torque from the engine to the vehicle wheels via an active clutch, wherein said active clutch is the first or the second clutch, the remaining clutch is an inactive clutch, said gear A and gear B are engaged, an active gear is downstream from said active clutch, said active gear is gear A or gear B, and an inactive gear is downstream from said inactive clutch, said inactive gear is gear A or gear B;
• (b) disengaging said inactive gear;
• (c) executing a zero correction on the first and second clutches;
• and,
• (d) re-engaging said inactive gear.

A method for adapting clutch characteristics when a vehicle is stationary, said vehicle having a twin-clutch system that comprises a first branch having a first clutch and a first partial transmission mounted downstream thereof, and a second branch having a second clutch and a second partial transmission mounted downstream thereof, said first and second partial transmissions comprising at least a gear A and at least a gear B, respectively, an engaged gear and a disengaged gear, said engaged gear is gear A or gear B, and the remaining gear is said disengaged gear, the first and second branches operatively arranged for connection to an engine on an input side and to vehicle wheels of the vehicle on an output side, and the first clutch being operated by a first clutch actuating mechanism and the second clutch being operated by a second clutch actuating mechanism, said method comprising the steps of:

• (a) executing a zero correction on a disengaged clutch, wherein said disengaged clutch is upstream from the disengaged gear and is the first clutch or the second clutch, the remaining clutch is an engaged clutch;
• (b) disengaging said engaged gear;
• (c) executing a zero correction on said engaged clutch;
• and,
• (d) re-engaging said engaged gear.

A method for adapting clutch characteristics when a vehicle is stationary, said vehicle having a twin-clutch system that comprises a first branch having a first clutch and a first partial transmission mounted downstream thereof, and a second branch having a second clutch and a second partial transmission mounted downstream thereof, said first and second partial transmissions comprising at least a gear A and at least a gear B, respectively, an engaged gear and a disengaged gear, said engaged gear is gear A or gear B, and the remaining gear is said disengaged gear, the first and second branches operatively arranged for connection to an engine on an input side and to vehicle wheels of the vehicle on an output side, and the first clutch being operated by a first clutch actuating mechanism and the second clutch being operated by a second clutch actuating mechanism, said method comprising the steps of:

• (a) disengaging said engaged gear;
• (b) executing a zero correction on the first and second clutches;
• and,
• (c) re-engaging said engaged gear.

A method for adapting clutch characteristics when a vehicle is stationary, said vehicle having a twin-clutch system that comprises a first branch having a first clutch and a first partial transmission mounted downstream thereof, and a second branch having a second clutch and a second partial transmission mounted downstream thereof, said first and second partial transmissions comprising at least a gear A and at least a gear B, respectively, said gears A and B engaged, the first and second branches operatively arranged for connection to an engine on an input side and to vehicle wheels of the vehicle on an output side, and the first clutch being operated by a first clutch actuating mechanism and the second clutch being operated by a second clutch actuating mechanism, said method comprising the steps of:

• (a) disengaging a first disengaged gear, wherein said first disengaged gear is gear A or gear B, the remaining gear is a second disengaged gear;
• (b) executing a zero correction on a first disengaged clutch, wherein said first disengaged clutch is mounted upstream from said first disengaged gear and is the first clutch or the second clutch, the remaining clutch is a second disengaged clutch;
• (c) engaging said first disengaged gear;
• (d) disengaging said second disengaged gear;
• (e) executing a zero correction on the second disengaged clutch;
• and,
• (f) engaging said second disengaged gear.

• (a) disengaging said gears A and B;
• (b) executing a zero correction on the first and second clutches;
• and,
• (c) re-engaging said gears A and B.
