Abstract
A method of controlling uphill driving of a hybrid vehicle provided with a dual clutch transmission (DCT) may include determining, by a controller, a driving state of a vehicle on the basis of information collected from the vehicle; when the vehicle is determined as being in a uphill driving state, performing, by the controller, high torque control on an engine of the vehicle by increasing an engine torque to control the engine at a predetermined high torque engine operating point and reducing a motor torque of a motor in the vehicle to satisfy a driver request torque; and during the performing of the high torque control on the engine, comparing, by the controller, a state of charge (SOC) value of a battery with a set first SOC threshold value, and when the SOC value of the battery is less than or equal to the first SOC threshold value, performing engine and motor speed control to defend the SOC value of the battery.
