The invention relates to vehicle rain sensing using modulated infrared transmission. A rain sensor in a vehicle includes a transmitter to implement pseudo-random modulation of transmission timing of infrared transmission toward a windshield of the vehicle. The rain sensor also includes a receiver that is active only within a specified period of time after each emission of the infrared transmission and receives reflections that encounter any substance on the windshield based on the infrared transmission.

    本发明涉及一种使用经调制的红外透射的车辆雨水感测。车辆中的雨水传感器包括发射器,以实施对朝向车辆挡风玻璃的红外透射的发射定时的伪随机调制。雨水传感器还包括接收器,该接收器仅在每次发射红外透射后的指定时间段内有效,并接收基于红外透射遇到挡风玻璃上任何物质的反射。
