Abstract
A shifting control method for a vehicle with a dual clutch transmission (DCT), the shifting control method may include controlling engine torque to be increased according to reserve demand torque by giving the reserve demand torque of an engine to be increased to a predetermined value or more when if a controller determines that the vehicle enters a manual power off and downshift shifting; controlling, by the controller, a release side clutch to be released; controlling, by the controller, an engine torque to perform a control so that engine speed follows coupling side input shaft speed; and completing the shifting by performing a control so that a coupling side clutch is coupled when it is determined that the actual shift is completed.
Claims7
A shifting control method for a vehicle with a dual clutch transmission (DCT), the shifting control method comprising:
- an initial shift step of controlling an engine torque to be increased according to a reserve demand torque by giving the reserve demand torque of an engine to be increased to a predetermined value or more when a controller determines that the vehicle enters a manual power off and downshift shifting;
- a clutch release step of controlling, by the controller, a release side clutch to be released;
- an actual shift step of controlling, by the controller, the engine torque so that engine speed follows a coupling side input shaft speed;
- and
- a shift completion step of completing shifting of the DCT by the controller so that a coupling side clutch is coupled when the controller determines that the shifting is completed.
