摘要： A clutch in a vehicle with DCT having an ISG function is controlled for an engine speed to be decreased rapidly when the engine enters into the ISG so that a ring gear of an engine and a gear of a starter motor are meshed more rapidly when a vehicle restarts, to thereby prevent a response delay when restarting the vehicle.

摘要： A shifting control method for a hybrid vehicle may include motor torque determination step, of determining the condition of a motor torque, by a controller, in a power-off downshift shifting process, gear mesh step, by the controller, of releasing a clutch of a releasing side and meshing a target shifting stage gear connected to a clutch of engaging side when the motor torque is positive (+) torque, an assist control step, of controlling, by the controller, the motor torque to 0 Nm, a rising step, by the controller, of controlling the motor speed to rise and follow a target motor speed predetermined higher than at least an input shaft speed of an engaging side after releasing the assist control, and an engaging step, by the controller, of engaging the clutch of the engaging side by a clutch torque of the engaging side when the motor speed exceeds the input shaft speed of the engaging side.

摘要： A method for controlling a transmission for a vehicle includes: sensing, by a controller, an opening degree of an accelerator pedal; checking, by the controller, a gear stage engaged with an input shaft, with which a Reverse (R) gear and a second gear of a Dual-Clutch Transmission (DCT) are engageable, if the opening degree of the accelerator pedal is less than or equal to a reference value as a result of the sensing; and controlling, by the controller, the vehicle in a parking mode in which disengagement of the R gear is prevented if the R gear is engaged with the input shaft as a result of the checking.

摘要： The present disclosure provides a driving control method for hybrid type vehicles with a DCT. The method includes: receiving the motor speed from a driving motor; when abnormality of the motor speed is detected, requesting driving of an engine and determining whether an engine clutch is engaged; if it is determined that the engine clutch is released, controlling a clutch of a current driving stage using a clutch torque higher than a transmission input torque; controlling the current driving stage to be a limp home driving stage set in advance to be in a limp home driven status.
