Abstract
A method and an apparatus for controlling an operation mode of a hybrid electric vehicle and a hybrid electric vehicle are provided in the present disclosure. The method includes: detecting a current state of charge of a power battery and an expected torque at wheels in the hybrid electric vehicle; maintaining a current operation mode of the hybrid electric vehicle, if it is detected that the current state of charge enters a state hysteresis area or the expected torque at wheels enters a torque hysteresis area; obtaining a duration of the current operation mode and determining a next operation mode of the hybrid electric vehicle according to the duration, the current state of charge and the expected torque at wheels, if it is detected that the current state of charge exits the state hysteresis area and the expected torque at wheels exits the torque hysteresis area. With the method, the problems of frequently switching from one operation mode to another operation mode may be avoided, the comprehensive performance of the hybrid electric vehicle and the fuel economy may be improved, and the user experience may be enhanced.
