An automatic rain response system includes a loudspeaker of a vehicle, a windshield wiper, and a controller. The loudspeaker generates an acoustic signal in response to rain. The controller is configured to receive a local weather condition, extract an acoustic feature from the acoustic signal, form a feature vector in response to the acoustic feature and the local weather condition, classify the feature vector to determine a current category among a plurality of categories, and determine a heavy rain category in response to the current category being a heavy rain category on the windshield. In one embodiment, the method includes activating the windshield wiper at a high speed, activating the windshield wiper at an intermediate speed in response to a current category being a freezing rain category on the windshield, activating the windshield wiper at a low speed in response to the current category being a light rain category on the windshield, and deactivating the windshield wiper in response to the current category being a rain-free category.

    一种自动雨水响应系统包括车辆的扩音器、挡风玻璃刮水器和控制器。扩音器响应于雨而生成声学信号。控制器被配置成接收当地天气状况,从声学信号中提取声学特征,响应于声学特征和当地天气状况形成特征向量,对特征向量进行分类以在多个类别当中确定当前类别,响应于当前类别是挡风玻璃上的大雨类别,以高速激活挡风玻璃刮水器,响应于当前类别是挡风玻璃上的冻雨类别,以中速激活挡风玻璃刮水器,响应于当前类别是挡风玻璃上的小雨类别,以低速激活挡风玻璃刮水器,以及响应于当前类别是无雨类别,去激活挡风玻璃刮水器。
