Abstract: A method and a system for shifting a gear of a hybrid electric vehicle are provided. The method includes following steps. A state of a battery is determined according to a remaining capacity of the battery, a required torque and a state of the hybrid electric vehicle, in which the state of the battery comprises a discharging state or a charging state. A plurality of optional target gears, a torque and a rotating speed of an engine corresponding to each optional target gear are determined according to the state of the battery and a speed of the hybrid electric vehicle. An optional target gear with a minimum fuel consumption of the engine is selected as a target gear from the plurality of optional target gears. It is determined whether to perform a gear shift by comparing with a current gear.
