  • Patent number: 10207702
    Abstract: A system and a method of controlling a hybrid electric vehicle shift are disclosed. The system includes an engine and a drive motor operating as power sources and a transmission receiving driving torque from one of the engine and the drive motor. A data detector detects a state data for operating the transmission. A vehicle controller calculates a creep torque and an engine setting torque using the state data, determines whether a shift control condition is satisfied based on a position value of an accelerator pedal, calculates an available motor torque using a motor speed at an actual shift start point and a target motor speed when the shift control condition is satisfied, and calculates a first shift input torque using the creep torque, the engine setting torque, the available motor torque, and a first torque apply ratio. The transmission is operated based on the first shift input torque.
