Patent ID: 7409885

Claim:
A method of controlling a twin-clutch transmission ( 10 ), wherein torque is transmitted from a drive shaft (I) to an output shaft (O) via a first clutch (C 1 ) and via a first transmission path (E 2 , Z 8 , Z 9 , S 2 , Z 3 , Z 4 ), and with a second clutch C 2 ) being at least partially closed in order to transmit an additional torque from the drive shaft (I) to the output shaft (O) via a second transmission path (E 1 , Z 1 , Z 2 , S 1 , Z 3 , Z 4 ; E 1 , Z 5 , Z 6 , S 3 , Z 7 ) when the torque transmitted by way of the first clutch (C 1 ) reaches a predetermined upper limit; said method comprising the steps of: comparing torque (M Mot ) provided by an engine with a current permissible upper limit for a selected gear and an operating mode of the transmission, said current permissible upper limit being selected to ensure that the first transmission path is protected from a torque overload; and diverting an excess component of the torque (M Mot ) via the second transmission path responsive to said current permissible upper limit being exceeded.
