1. A driving control method of a hybrid electric vehicle, comprising:
entering a catalyst heating control of an engine when there is a request for catalyst heating and a required torque exceeds a first threshold during traveling in a first mode, using an electric motor as a driving source; and
entering an acceleration feeling increase control in an idle state where engine power is not transferred to wheels of the vehicle, when the required torque exceeds a second threshold that is greater than the first threshold and less than a third threshold,
wherein the second threshold is set between the first threshold and the third threshold, and the third threshold is a reference for an entry into a second mode using the engine as the driving source from the idle state.
