Abstract

The invention discloses a rain sensor test system. The system comprises a rain sensor arranged on a windscreen, a rainfall simulation device used for simulating various rain conditions, a windscreen wiper control device used for controlling a windscreen wiper to operate according to rainfall signals sent by the rain sensor under different rain conditions, and a calibration test device used for testing and calibrating the rain sensor according to the rainfall signals and the operation state of the windscreen wiper. The system has the beneficial effects that operation is easy, repeatability is high, the influence caused by natural environment factors is effectively reduced, plenty of manpower and material resources are saved, a test condition can reappear, a test period can be shortened, anda research and development schedule is guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle wiper system testing, in particular to a rain sensor testing system. Background technique [0002] In the process of automobile production and research and development, intelligence has developed into the mainstream of research and development. All operating manufacturers are focusing on research and development on how to improve the driving assistance functions of cars. [0003] The rain sensor in the vehicle wiper system can automatically identify whether there is water in the sensing area and the amount of water, so as to judge the size of the rain, and feed back the information to the body controller, which can automatically control the wiper and automatically adjust the wiper through the body controller speed, realize the automatic wiper function, eliminate the driver's repeated operation, and improve driving safety and comfort. [0004] The working principle of the rain sensor is based on the total ...
