The invention particularly relates to a novel high-precision automobile rain sensor which is high in detection precision and capable of effectively improving the driving safety sense. The rain sensor comprises a base, a plurality of fan-shaped vertical plates are arranged on the outer surface of the base, and the outer surface of the base is divided into a plurality of independent unit spherical surfaces through fan-shaped transverse plates; the polarities of the two current-conducting plates on the two sides of one insulating plate are opposite, and a voltage difference is kept between the current-conducting plates on the two sides of the single unit spherical surface; the rainfall sensor is high in measurement precision and high in environmental adaptability, rainfall and the incident angle of rainwater can be measured, the actual wiping speed of the windscreen wiper is adjusted according to the rainfall and the incident angle of the rainwater, and the psychological security of a driver is effectively improved; in addition, the actual wiping speed of the windscreen wiper can be adjusted in the accelerated driving state, the ramp driving state and the steering driving state according to different driving states of the automobile, and the driving safety is improved.
本发明具体涉及一种检测精度高、有效提高驾驶安全感的新型高精度汽车用雨量传感器,雨量传感器包括基座,基座的外表面设置多个扇形竖板、扇形横板将基座的外表面分隔成多个相互独立的单元球面;位于一个绝缘板两侧的两个导电板的极性相反,保持单个单元球面两侧的导电板之间具有电压差;雨量传感器测量精度高,环境适应性强,且可以测量降雨量及雨水的入射角度,根据降雨量和雨水入射角度调节雨刮器实际刮扫速度,有效提高驾驶员的心里安全感;雨刮器实际刮扫速度还可根据汽车的不同行驶状态,在加速行驶、坡道行驶、转向行驶状态下分别调整雨刮器实际刮扫速度,提高驾驶安全性。
