Patent ID: 7967723

Claim:
A method of operating an automatically synchronized transmission ( 1 ), of a countershaft design for a motor vehicle, comprising: a countershaft ( 4 ) located parallel to an input shaft ( 2 ) and an output shaft ( 3 ), the input shaft ( 2 ) and the output shaft ( 3 ) are drive-effectively connected with one another and with the countershaft ( 4 ) via mating gear wheel pairs, and the transmission ( 1 ) including at least one coupling and synchronization device ( 30 , 30 ′, 30 ″, 30 ′″) for at least one idler gear ( 10 ′, 12 ′, 14 ′, 16 ′, 18 ′, 20 ′) such that the at least one idler gear can be connected with the output shaft ( 3 ) in a rotationally fixed manner, the method comprising the step of: when the motor vehicle is at a standstill and a starting gear is engaged, reducing an actual torque of the countershaft ( 4 ), via a decelerating device, to a level that prevents unwanted vehicle movement upon engaging the starting gear; and determining that the actual torque of the countershaft ( 4 ) is greater than a predetermined torque limit, such that an acceleration of the vehicle would be detected upon engaging the starting gear without activation of an actuator, before activating at least one actuator in the drive train of the vehicle.
