DCT control method for vehicle

摘要

The noise caused by the coupling and decoupling of the gear generated when ignition on and off of a dual-clutch mounted vehicle in the P range are switched to each other, and the merchantability of the vehicle can be increased by improving the noise performance of the vehicle by preventing the noise generated by the coupling of the gear as possible from being remarkable in other shift ranges.

主权项

1. A Dual Clutch Transmission (DCT) control method for a vehicle, comprising:
verifying a range where a shift lever is positioned during an ignition-off mode, to form an off-time range verifying step; holding a current state, to form a shift stage holding step, when an odd stage and an even stage of a DCT are in a first stage and an Reverse (R) stage, respectively in the case where the shift lever is positioned in a Park (P) range as a result of performing the off-time range verifying step; verifying a range where the shift lever is positioned during ignition-on, to form an on-time range verifying step; and respectively coupling the first stage and the R stage after waiting until an engine is cranked when the odd state and the even state are not coupled to the first stage and the R stage, respectively in the case where the shift lever is positioned in the P range or the R range, as a result of performing the on-time range verifying step, to form a 1R cranking waiting step.
