Method for controlling the shifting of an automated twin-clutch transmission |
摘要 |
A method for controlling the shifting operation of an automated twin-clutch transmission includes executing a shifting operation between a load gear and a target gear assigned to a first transmission unit by using an intermediate gear assigned to a second transmission unit. The engine speed is adjusted to reach the synchronous speed of the target gear at the end of the shifting operation. At the start of the shifting operation an initial target speed gradient is set such that the engine speed reaches the synchronous speed at the end of the shifting operation based on an estimated total shifting time. The actual shifting progress is determined during the shifting operation and is compared with the estimated shifting progress. The target speed gradient is adjusted to the actual shifting progress in case the actual shifting progress and the estimated shifting progress deviate from one another.
