Disclosed are an apparatus and a method for controlling driving of a hybrid vehicle. The method for controlling driving of the hybrid vehicle according to an embodiment of the present invention comprises the steps of: determining an engine torque command value which constantly increases at a constant torque increase rate according to the preset slope when a blend over control mode is set according to a driver′s demand for acceleration; determining a motor torque command value based on a motor RPM and a fixed power rate; supplying the engine torque command value and the motor torque command value to an engine controller and a motor controller, respectively so as to carry out blend over; and carrying out a slip control by total torque when an input torque of a transmission is added to keep a constant output torque of the transmission, so that an engine torque control time and an electric motor control time to which response delay time of the engine torque control command and the electric motor torque control command is reflected are exactly synchronized, thereby removing asynchronous shock caused during the blend over control according to the driver′s demand for acceleration and preventing deterioration in riding comfort due to the asynchronous shock.
