controlling the first synchronizer to be in a state of being combined with the second-gear input gear and separated from the fourth-gear input gear, simultaneously controlling the second synchronizer to be in a state of being separated from both the first-gear output gear and the third-gear output gear, and switching the gear of the gearbox to the second gear;
controlling the first synchronizer to be in a state of being separated from both the fourth-gear input gear and the second-gear input gear, simultaneously controlling the second synchronizer to be in a state of being combined with the third-gear output gear and separated from the first-gear output gear, and switching the gear of the gearbox to the third gear;
and controlling the first synchronizer to be in a state of being combined with the fourth-gear input gear and separated from the second-gear input gear, and controlling the second synchronizer to be in a state of being separated from both the first-gear output gear and the third-gear output gear, so that the gear of the gearbox is switched to the fourth gear.
10. Vehicle, characterized in that it comprises a step-change transmission according to any one of claims 1 to 9.
