Abstract
A method of controlling gear shift for a hybrid vehicle with a dual clutch transmission (DCT) may include making a request for reduction in transmission input torque at a time point of entrance into down shift to a first stage from a second stage, determining whether the vehicle is accelerated via manipulation of an accelerator pedal during the down shift, and controlling to begin to gradually reduce an transmission input torque reduction request amount in a torque phase period in which clutch torque is exchanged after a first-stage gear is engaged upon determining that the vehicle is accelerated during the gear shift.
Claims11
A method of controlling gear shift for a hybrid vehicle with a dual clutch transmission (DCT), the method comprising:
- an input torque reduction operation of making, by a controller, a request for reduction in transmission input torque at a time point of entrance into down shift to a first stage from a second stage;
- an acceleration determination operation of determining, by the controller, when the vehicle is accelerated via checking of manipulation of an accelerator pedal during the down shift;
- and
- a torque reduction amount decreasing operation of controlling, by the controller, to begin to reduce a transmission input torque reduction request amount in a torque phase period in which clutch torque is exchanged after a first-stage gear is engaged when the controller determines that the vehicle is accelerated during the gear shift.
