Specifically, when the current gear state is the fourth state, if the duration of the second rotational speed difference between the driving portion and the driven portion of the current gear clutch is greater than the time threshold, the manner of determining the transmission input shaft torque corresponding to the current gear state according to the target gear ratio and the current transmission output shaft torque may be: the whole vehicle controller controls the torque of a transmission input shaft output by a power motor and an engine to be higher than the sum of the transmission torque capacity of a current gear, the transmission torque capacity of a target gear corresponding to a third state and a preset threshold value, so that the duration time of a second rotational speed difference between a driving part and a driven part of the current gear clutch is larger than a time threshold value, namely, a fixed second rotational speed difference is kept, when the current gear state is a fourth state, the target gear speed ratio and the torque of a current transmission output shaft are obtained, and the torque of the transmission input shaft corresponding to the current gear state is determined according to the target gear speed ratio and the torque of the current transmission output shaft. For example, the transmission input shaft torque corresponding to the fourth state may be calculated by: transmission input shaft torque=current transmission output shaft torque/target gear ratio for the fourth state.
