Automotive glass system capable of automatic defrosting and demisting, defrosting method and demisting method

Abstract

The invention relates to the defrosting and demisting fields of glass products, in particular to the temperature measurement technologies of electric heating glass, and concretely provides an automotive glass system capable of automatic defrosting and demisting, a defrosting method and a demisting method. The automotive glass system capable of automatic defrosting and demisting comprises automotive glass and a power source and further comprises a control unit, a humidity sensor and a current measurement device / resistance measurement device. The humidity sensor is arranged in an automobile to measure the moisture content d of air inside the automobile. The current measurement device / resistance measurement device can measure current I or resistance R of an electric heating element after the electric heating element is powered on. According to the automotive glass system, the defrosting method and the demisting method, the potential safety hazard that glass misting affects the sight of a driver can be eliminated, the safety performance and comfort of automobile driving are improved, and meanwhile a good energy-saving effect is achieved; in the defrosting process, the operation of the driver is simplified, unnecessary energy waste is avoided, the waiting time of the driver in the defrosting process is shortened, and user experience is improved.

Description

Technical field: [0001] The invention relates to the field of defrosting and defogging of glass products, in particular to the temperature measurement technology of electrically heated glass, and specifically provides a system and method for measuring the temperature of electrically heated glass by using the temperature coefficient of resistance, and also provides a method capable of An auto glass system for automatic defrosting and defogging, and a defogging and defrosting method. Background technique: [0002] In cold weather, frosting tends to occur on automobile glass and building glass; or when the humidity inside and outside the car is high, and the temperature and the external environment are greatly different, fogging is also prone to occur on automobile glass and building glass; Thereby affecting the observation line of sight inside and outside the car and their appearance, especially the front windshield glass of the car that provides a good view for the driver. If...
