The invention relates to the technical field of vehicles, in particular to a control method and device for a cooling fan of a motor controller, a vehicle and a storage medium, and the method comprises the steps that when it is detected that the motor controller of the vehicle is in a preset fault mode, the cooling fan is controlled by using a first target fan opening degree, and otherwise, the cooling fan is controlled by using a second target fan opening degree; when it is judged that the motor controller is in the torque mode or the target fault mode, the second target fan opening degree of the cooling fan is determined according to the motor rotating speed, the motor torque and the IGBT temperature of the motor controller so as to control the cooling fan. According to the embodiment of the invention, the cooling fan can be controlled by utilizing the first target fan opening degree under the condition that the motor controller is in a certain fault mode, otherwise, the cooling fan is controlled by utilizing the second target fan opening degree when the motor controller is judged to be in the torque mode or the target fault mode, and the control accuracy of the cooling fan is improved. Therefore, the noise reduction reliability of the cooling fan is improved, and the driving comfort of a user is improved.
本申请涉及车辆技术领域,特别涉及一种电机控制器冷却风扇的控制方法、装置、车辆及存储介质,方法包括:在检测到车辆的电机控制器处于预设故障模式的情况下,利用第一目标风扇开度对冷却风扇进行控制,否则,在判定电机控制器处于扭矩模式或者目标故障模式时,根据电机控制器的电机转速、电机扭矩和IGBT温度确定冷却风扇的第二目标风扇开度,以对冷却风扇进行控制。本申请实施例可以在电机控制器处于一定的故障模式的情况下,利用第一目标风扇开度对冷却风扇进行控制,否则,在判定电机控制器处于扭矩模式或者目标故障模式时,利用第二目标风扇开度对冷却风扇进行控制,从而提升冷却风扇降噪的可靠性,并且提升用户驾乘的舒适性。
