Abstract

The present disclosure relates to a hybrid electric vehicle configured to respond to a required torque while reducing exhaust gas emission in a situation where catalyst heating of an engine is not completed, and a driving control method for the hybrid electric vehicle. The driving control method of the hybrid electric vehicle comprises entering 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 acceleration feeling increase control when the required torque exceeds a second threshold greater than the first threshold, in which the second threshold is set between the first threshold and a third threshold that is a reference for an entry into a second mode using the engine as the driving source.
