Correction method of rain sensor module, device thereof and readable storage medium

Abstract

The invention discloses a correction method of a rain sensor module, wherein the correction method is applied to an upper computer. The method comprises the steps of setting a standard mode and operating a rain control program so that a rain sprinkling testing box generates a rain sprinkling environment which corresponds with the standard mode; acquiring a current output mode which is obtained through actual measurement on the rain sprinkling environment by the rain sensor module on glass through CANcaseXL; determining whether the current output mode corresponds with the standard mode, and ifnot, correcting a calibration coefficient in the rain sensor module. According to the correction method, through correcting the calibration coefficient in the rain sensor module, an original error ofthe sensor module in actual application and an error in matching the glass are corrected, and relatively high testing accuracy of the rain sensor module is realized. Because controlling for quality and parameters of a single element is not required, cost reduction and calibration precision improvement are realized. The invention correspondingly discloses a correction device of the rain sensor module, and a readable storage medium.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a correction method, device and readable storage medium for a rain sensor module. Background technique [0002] With the prosperity, development and popularity of automobiles, users have gradually increased their requirements for automobiles. In addition to safety, the pursuit of ease of use and novelty has also been continuously strengthened. These pursuits have increased the space for the realization of automatic wiper functions. Automatic wiper The application requirements for the scraping function are rapidly expanding. [0003] The rain sensor, as one of the important modules of the automatic wiper function, is generally used to measure the rain in the external environment. It has an LED light-emitting diode responsible for sending infrared rays. When the glass surface is dry, the light is almost 100% reflected back. In this way, the photodiode can receive the correspo...
