Disclosed herein are system, method, and computer program product embodiments for cleaning one or more sensors of an automatic driving system (SDS). For example, the SDS is provided with a sensor with a lens, and the lens is formed with a convex outer surface. The nozzle is formed with an opening to provide a flow of liquid at a sector angle relative to the ejection axis. The nozzle is spaced apart from the sensor by a distance based on the radius and sector angle of the lens, and is configured to eject liquid in a laminar flow onto the proximal end of the lens such that the liquid flows from the proximal end of the lens to the distal end to remove debris.
本文公开了用于清洁自动驾驶系统(SDS)的一个或多个传感器的系统、方法和计算机程序产品实施例。例如,SDS设置有带镜头的传感器,镜头形成有凸外表面。喷嘴形成有开口,以相对于喷射轴线以扇形角提供液体流。喷嘴与传感器间隔开基于镜头的半径和扇形角的距离,并且被构造成将液体以层流喷射到镜头的近端上,使得液体从镜头的近端流过镜头到远端以去除碎屑。
