Shift control method for vehicle with DCT

A controller for use in a vehicle with a dual-clutch transmission (DCT), the controller being configured to:

• determine whether or not a power-on upshift is initiated in a state in which a high performance mode has been selected;
• perform a torque phase in which a coupling-side clutch torque is gradually increased and a release-side clutch torque is gradually released, the coupling-side clutch torque being gradually increased to a target coupling-side clutch torque corresponding to a value obtained by adding a push feel torque to a base torque;
• perform an inertia phase in which the coupling-side clutch torque is gradually increased while tracing an engine torque such that an engine speed is synchronized with a coupling-side clutch speed;
• and
• complete speed change through gradual decrease of the coupling-side clutch torque.

A vehicle with a dual-clutch transmission (DCT), the vehicle comprising:

• a first clutch;
• a second clutch;
• a first shift actuator;
• a second shift actuator;
• and
• a controller coupled to the first clutch, the second clutch, the first shift actuator, and the second shift actuator, the controller configured to:
• determine whether or not a power-on upshift is initiated in a state in which a high performance mode has been selected;
• perform a torque phase in which a coupling-side clutch torque is gradually increased and a release-side clutch torque is gradually released, the coupling-side clutch torque being gradually increased to a target coupling-side clutch torque corresponding to a value obtained by adding a push feel torque to a base torque;
• perform an inertia phase in which the coupling-side clutch torque is gradually increased while tracing an engine torque such that an engine speed is synchronized with a coupling-side clutch speed;
• and
• complete speed change through gradual decrease of the coupling-side clutch torque.
