Abstract:
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.
