본 발명의 양상들은 일반적으로 도로 날씨 상황들을 검출하는 것에 관한 것이다. 레이저(310, 311), 강수량 센서들(340), 및/또는 카메라들(320, 322)을 포함하는 차량 센서들은 도로의 밝기, 도로의 밝기의 변화들, 세계의 밝기, 현재 강수량뿐만 아니라 도로의 검출된 높이와 같은 정보를 검출하기 위해 사용된다. 네트워크 기반의 날씨 정보(일기예보들, 레이더, 강수 보도들 등)와 같은 다른 소스들로부터 수신된 정보 또한 고려된다. 상기 수신된 정보 및 검출된 정보의 조합은 도로의 물, 눈, 또는 얼음과 같은 강수 확률을 추정하기 위해 사용된다. 이 정보는 이후에 자율 주행차(101)를 (조종, 가속, 또는 브레이크를 위해)조작하거나 위험한 상황들을 식별하기 위해 사용된다.

    The invention relates to detecting road weather conditions, namely an at least partly snow covered road. Vehicle sensors including a laser 310, 311, precipitation sensors 340, and/or cameras 320, 322 may be used to detect information such as the brightness of the road, variations in the brightness of the road, brightness of the world, current precipitation, as well as the detected height of the road. Information received from other sources such as networked based weather information (forecasts, radar, precipitation reports, etc.) may also be considered. The combination of the received and detected information may be used to estimate the probability of precipitation such as water, snow or ice in the roadway. This information may then be used to maneuver an autonomous vehicle 101 (for steering, accelerating, or braking) or identify dangerous situations.
