HYBRID ELECTRIC VEHICLE, METHOD AND APPARATUS FOR CONTROLLING OPERATION MODE OF THE SAME

BORGWARD TRADEMARK HOLDIN...

1. A method performed by a computing device for controlling an operation mode of a hybrid electric vehicle, comprising: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;
wherein the 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 comprises:
judging whether the duration exceeds a preset period;
maintaining continually the current operation mode if the duration does not exceed the preset period; and
determining the next operation mode according to the current state of charge and the expected torque at wheels and switching to the next operation mode, if the duration exceeds the preset period.
