摘要： A method of operating a vehicle drive train with a drive machine and a transmission device during a coasting upshift, during which at least one interlocking shift element that is engaged in the force flow of the transmission device, to produce the gear ratio to be disengaged, is disengaged from the force flow, and a frictional shift element that has to be engaged, in the force flow of the transmission device to obtain the gear ratio to be engaged, is engaged in the force flow. When a shift command is given for a gear ratio change, torque applied at the interlocking shift element to be disengaged is reduced to at least approximately zero, by a defined engine intervention, and the interlocking shift element is then disengaged from the force flow of the transmission device.

摘要： The invention relates to a method for operating a transmission device (10) of a vehicle drivetrain having a plurality of frictional switching elements (A, C to E) and at least one interlocked switching element (B) for implementing various ratios (“1” to “R”). In the neutral operating mode of the transmission device (10), and when an operating mode distribution of the vehicle drivetrain is present for which the at least one interlocked switching element (B) is to be transitioned from an opened to a closed operating mode upon a request for producing the power flow in the transmission device (10), a differential speed in the region of the interlocked switching element (B) is determined by releasing the transmission capabilities of at least two frictional switching elements (A, C) that are to be closed for producing the power flow, wherein a drive torque of a drive machine (9) is adjusted to a level leading to the differential speed in the range of the interlocked switching element (B) within a predefined differential speed range, within which the interlocked switching element (B) at least approximately comprises a synchronous state and can be closed.

摘要： A method of operating a vehicle drive train with a drive machine and a transmission device during a coasting upshift, during which at least one interlocking shift element that is engaged in the force flow of the transmission device, to produce the gear ratio to be disengaged, is disengaged from the force flow, and a frictional shift element that has to be engaged, in the force flow of the transmission device to obtain the gear ratio to be engaged, is engaged in the force flow. When a shift command is given for a gear ratio change, torque applied at the interlocking shift element to be disengaged is reduced to at least approximately zero, by a defined engine intervention, and the interlocking shift element is then disengaged from the force flow of the transmission device.
