Front windshield having function of detecting rainfall and fog and automobile having same

Abstract

The invention provides a front windshield having a function of detecting rainfall and fog. The front windshield comprises an outer glass plate and an inner glass plate between which at least a first transparent conductive layer for sensing the rainfall and a second transparent conductive layer for sensing the fog are arranged. On the first transparent conductive layer, at least three mutually insulated transparent rainfall detecting electrodes are disposed in an area corresponding to a rainfall sensing area, and a first transparent electrode is disposed in an area corresponding to a fog sensing area and serves as a rainfall shielding layer of the detection area of a fog capacitive sensor. On the second transparent conductive layer, at least two independent and mutually insulated transparent fog detecting electrodes are disposed in an area corresponding to a fog sensing area, and a second transparent electrode is disposed in an area corresponding to the rainfall sensing area and servesas a fog shielding layer of the detection area of a rainfall capacitive sensor. The front windshield can prevent the fogging on the surface of the inner glass plate from affecting a rainfall detectingcapacitor and the rainwater outside the outer glass plate from affecting a fog detecting capacitor, thereby improving detection precision.

Description

technical field [0001] The invention relates to a glass, in particular to a front windshield with the function of detecting rain and fog and an automobile containing the windshield. Background technique [0002] The traditional rain and fog sensor used to detect the amount of rain and fog on the windshield of the car is set inside the windshield. Although this setting method can measure the amount of rain and fog on the windshield, this setting method has the following defects: [0003] 1. The electrodes of the traditional rain and fog sensors are made of opaque materials, so the electrodes of the rain and fog sensors are required to be set at a certain position on the windshield, and cannot be set at any position on the windshield. This setting method will lead to inaccurate fog and rain measured by the rain and fog sensor. This is because the rain and fog are distributed discretely on the windshield, so the rain and fog sensor installed at a certain position on the windshi...

AI Technical Summary

Problems solved by technology

[0003] 1. The electrodes of the traditional rain and fog sensors are made of opaque materials, so the electrodes of the rain and fog sensors are required to be set at a certain position on the windshield, and cannot be set at any position on the windshield

This setting method will lead to inaccurate fog and rain measured by the rain and fog sensor. This is because the rain and fog are distributed discretely on the windshield, so it is very likely that the rain and fog sensor installed at a certain position on the windshield will The rain and fog on the windshield cannot be detected in time, so that the amount of rain and fog detected by the traditional rain and fog sensor is inaccurate, and eventually the wiper system and defogging system on the car cannot be activated in time

[0004] 2. The traditional rain and fog sensor requires huge space requirements, and the traditional setting method of setting the two electrodes of the fog detection capacitor and the rain detection capacitor on the glass will affect the aesthetics of the windshield and cannot meet the visual requirements of users

[0007] When the above-mentioned capacitive sensor detects the rainfall outside the car, the fog inside the car will interfere with the capacitive sensor, and the temperature and electromagnetic changes outside the car will also interfere with the capacitive sensor, thus causing the above-mentioned capacitive sensor to be inaccurate. The amount of rain outside the car can be accurately detected, and the capacitive sensor cannot feed back the accurate rain signal to the controller that controls the wiper action to control the wiper system to perform corresponding actions; at the same time, when the above-mentioned capacitive sensor detects the amount of fog in the car, Rainfall outside the car, temperature inside the car, electromagnetic changes, etc. will also cause interference to the capacitive sensor, resulting in the inability of the capacitive sensor to accurately detect the amount of fog, which in turn leads to the inability of the capacitive sensor to feed back an accurate signal of fog amount To control the air conditioner controller to control the air conditioner defogging system to perform corresponding actions
