摘要:
A method for controlling gear shifting, including: acquiring a current gear-shifting parameter of the vehicle (101); according to the current gear-shifting parameter and a preset target rotational speed, determining a gear-shifting inputted rotational speed (102); and when a rotational speed of the vehicle reaches the gear-shifting inputted rotational speed, controlling a shifting fork to start up a gear-shifting operation (103). The method for controlling gear shifting presets the target rotational speed of the gears, and, according to the current gear-shifting parameter of the vehicle that is acquired in real time and the preset target rotational speed, inversely calculates the gear-shifting inputted rotational speed, whereby the gear-shifting inputted rotational speed is an accurate gear-shifting inputted rotational speed that matches with the current condition of the vehicle. When the rotational speed of the vehicle reaches the gear-shifting inputted rotational speed, the shifting fork is controlled to start up a gear-shifting operation, which can realize the accurate gear shifting of the vehicle, which greatly improves the stability of the vehicle when a dual-clutch automatic transmission is performing gear shifting.
