The invention relates to a blade locked-rotor fault judgment method and device for an air-inlet grille, a medium and a vehicle. The blade locked-rotor fault judgment method for the air inlet grille comprises the steps that target parameters are obtained, and the target parameters are parameters influencing blade rotation; target torque of the motor is determined according to the target parameters, and the larger the influence degree of the target parameters on rotation of the blades is, the larger the target torque is; a first motor control instruction containing the target torque and the preset rotation angle is sent to a motor of the air inlet grille; and according to the preset rotation angle and an actual rotation angle fed back by the motor in response to the first motor control instruction, whether the blade has a locked-rotor fault or not is judged. According to the technical scheme of the invention, accurate detection of the locked-rotor fault of the blade can be realized.
本公开涉及一种进气格栅的叶片堵转故障判断方法、装置、介质及车辆。其中,进气格栅的叶片堵转故障判断方法包括:获取目标参数,所述目标参数为影响叶片转动的参数;根据所述目标参数,确定电机的目标扭矩,所述目标参数对叶片转动的影响程度越大,所述目标扭矩越大;向进气格栅的电机发送包含所述目标扭矩以及预设转动角度的第一电机控制指令;根据所述预设转动角度以及所述电机响应于所述第一电机控制指令而反馈的实际转动角度,判断所述叶片是否发生堵转故障。本公开技术方案能够实现对叶片堵转故障的精准检测。
