Electric vehicle power electronic component noise generation diagnosis device and noise diagnosis method based on artificial intelligence

An embodiment of the present invention relates to a noise generation diagnostic apparatus based on artificial intelligence and a method of diagnosing noise of a power electronic (PE) component of an electric vehicle, in which a plurality of microphones are arranged inside the vehicle, and the calculation unit measures the position of a noise source in any one or more of the power electronic (PE) components including the main motor, the decelerator, the inverter, and the auxiliary motor in the forward, rearward, and upward directions of the microphone while estimating a noise transmission position. 本发明的实施方式涉及一种基于人工智能的噪声产生诊断装置和诊断电动车辆的电力电子(PE)部件的噪声的方法，其中多个麦克风布置在车辆内部，并且计算单元测量包括主电机、减速器、逆变器和辅助电机在内的任何一个或多个在麦克风的前、后和向上方向上的电力电子(PE)部件中的噪声源的位置，同时估计噪声传输位置。
