This application discloses a hybrid electric vehicle, and a power system and a power generation control method thereof. The power system includes: an engine, configured to output power to a wheel of the hybrid electric vehicle through a clutch; a power motor, configured to output driving power to a wheel of the hybrid electric vehicle; a power battery, configured to supply power to the power motor; a DC-DC converter;a low-voltage storage battery, connected to the low-voltage storage battery and the DC-DC converter; a secondary motor, connected to the engine, where the secondary motor is connected to the power motor, the DC-DC converter, and the power battery separately, and the secondary motor is driven by the engine to generate power; a control module, configured to obtain an SOC value of the power battery, an SOC value of the low-voltage storage battery, and a maximum allowable generating power of the secondary motor, and determine, according to the SOC value of the power battery, the SOC value of the low-voltage storage battery, and the maximum allowable generating power of the secondary motor, whether the secondary motor charges the power battery and/or the low-voltage storage battery, so that low-speed electric balance and low-speed smoothness of the whole vehicle can be maintained.
