The invention discloses an automatic lamplight/automatic rain wiping realizing method according to an external environment. A rainfall illumination sensor is installed on a windscreen, the rainfall illumination sensor is connected with a BCM (body control module) controller through an LIN (local interconnect network) bus, and the BCM controller is further connected with a rain wiper motor, a low beam light and a position light; the rainfall illumination sensor obtains water vapor information through an internal optical component of the rainfall illumination sensor after being activated, and judges whether to send rain wiping control and corresponding control mode requests by combining with a set sensitivity; the rainfall illumination sensor can also identify environment light of the outside world and judges whether to send a lamplight control request to the BCM controller according to the condition of the environment light. The automatic lamplight/automatic rain wiping function is realized according to the condition of the external environment, automobile intelligentization and humanization can be enhanced and the driving comfort can be improved.
