This application relates to the field of vehicle control, specifically to a method for controlling a sunroof and a vehicle. This application, upon responding to a sunroof opening operation, compares the actual opening degree of the sunshade with the maximum driven opening degree to clarify the relationship between the two, thus mitigating the risk of premature sunroof opening from the control source. Secondly, based on the comparison results, a targeted motion strategy is formulated. If the actual opening degree of the sunshade already meets the maximum driven opening degree, the sunroof can be directly controlled to open normally. If not, the strategy is adjusted to ensure that the sunroof movement does not exceed the sunshade's adaptation range, avoiding an imbalance in the two opening degrees. Finally, this control logic does not require modification of the existing independent mechanical structure. Through linked judgment and strategy adjustment, it achieves dynamic adaptation between the sunroof opening and the sunshade opening degree, completely solving the problem of sunshade damage due to airflow impact and friction during driving caused by mismatched opening degrees, ensuring component lifespan and driving safety.

Based on the flux linkage hysteresis signal and the torque hysteresis signal, the voltage vector required for control is determined. Then, the axial force is controlled within the control range of (-15°, 15°) where the rotor position is selected.
