The invention discloses application of a rainfall light sensor to a commercial vehicle. The rainfall light sensor comprises a rainfall tube sensor, a sensor controller MCU, a night lamp L1 and a dipped headlight L2. The rainfall lamp tube sensor and the sensor controller MCU are integrated in a shell and installed on a front windshield of a commercial vehicle, the sensor controller MCU is connected with an automatic windscreen wiper switch K1 and an automatic lamplight switch K2, and the sensor controller MCU is connected with a night lamp L1 and a dipped headlight L2 in a relay communication mode or a CAN communication mode. The system is suitable for low-configuration and high-low-configuration vehicle models, the low-configuration vehicle models are not provided with CAN bus communication systems, and automatic control over the windscreen wiper and lamplight can be achieved in a relay control mode; a CAN bus communication system is configured for a high-configuration vehicle model, after a sensor controller MCU collects information, the information is sent to a vehicle control unit VCU through a CAN bus, and a windscreen wiper and lamplight are directly driven.
本发明公开了一种雨量灯光传感器在商用车上的应用,包括雨量灯管传感器、传感器控制器MCU、夜灯L1和近光灯L2;所述雨量灯管传感器和传感器控制器MCU集成在一个壳体内并安装在商用车前挡风玻璃上,传感器控制器MCU上连接有自动雨刮开关K1和自动灯光开关K2,传感器控制器MCU通过继电器通讯方式或CAN通讯方式与夜灯L1和近光灯L2相连,本发明适用于低配和高低配车型,低配车型未配置CAN总线通讯系统,可采用继电器控制方式实现雨刮器和灯光自动控制;高配车型配置了CAN总线通讯系统,传感器控制器MCU采集到信息后,通过CAN总线发送给整车控制器VCU,直接驱动雨刮器和灯光。
