Abstract: A shifting control method of a vehicle includes inhibiting, by a controller, a line pressure from being increased when the controller senses a power-off upshift condition of the vehicle, calculating, by the controller, a target speed of a motor after the inhibiting step, synchronizing, by the controller, the motor to the target speed after the calculating step, and increasing, by the controller, an oil pressure of an engagement side clutch of a transmission to complete shifting after the synchronizing step.

Abstract: A method for determining a connection state of an engine clutch includes: a stroke sensing operation of sensing, by a controller, a change of an actuator stroke of the engine clutch; a first pressure comparing operation of determining whether or not an actuator pressure of the engine clutch exceeds a first set pressure and is then changed to below the first set pressure when the actuator stroke is increased; a torque comparing operation of comparing transfer a torque of the engine clutch with a set torque when the actuator pressure exceeds the first set pressure and is then operated to below the first set pressure; and an open determining operation of determining that the engine clutch is in an open state when the transfer torque of the engine clutch is the set torque or less.

Abstract: A method for controlling gear shifting of a hybrid electric vehicle, which is configured for reducing gear-shifting time, minimizing loss by a drive system, improving fuel efficiency and enhancing drivability and which enables a driver to feel a change in acceleration when the driver manipulates the accelerator pedal during power-on upshift active control operation may include speed control of the driving source of the vehicle based on a change rate of a transmission input speed and feedforward control of the clutch of the engagement element in the transmission, to which a driver requested torque is reflected, which are performed at the same time during power-on upshift active control operation, facilitating the driver to feel a change in acceleration which is produced by his or her driving manipulation.
