摘要： Disclosed are a hybrid electric vehicle and a driving control method therefor, which are capable of switching to a driving mode and performing a kick-down shift more quickly. In particular, the method for controlling the hybrid electric vehicle includes: determining a first motor directly connected to an engine and an available torque in a target gear of each second motors connected to the first motor when a driving mode is changed from an electric vehicle (EV) mode to a hybrid electric vehicle (HEV) mode and a kick-down shift is required simultaneously; and determining operating points of the first motor and the second motor before an actual shift ends, based on the determined available torque and the type of kick-down shift.

摘要： A hybrid electric vehicle controlling a fuel injection point-in-time and a method of controlling driving of the hybrid electric vehicle such that fuel efficiency is improved when engine start is required. The method of controlling driving of the hybrid electric vehicle may include: inhibiting engine injection when there is an engine start request and a control entry condition is satisfied, performing the engine injection when an injection allowable condition is satisfied with the engine injection inhibited, and performing reaction force control along with the engine injection through a first motor directly connected to the engine.
