The invention relates to the technical field of vehicle
fog prevention, in particular to an anti-instantaneous-
fogging system for vehicle window glass, an anti-instantaneous-
fogging method therefor and a vehicle. The anti-instantaneous-
fogging system comprises an acquisition module, a judging module and a control module, wherein the acquisition module is used for acquiring vehicle
relevant information which comprises outside temperature information, parking
time information, in-vehicle demand temperature information, and in-vehicle actual temperature information; the judging module is used forjudging whether a vehicle window reaches an instantaneous fogging condition according to the vehicle
relevant information; the control module is used for controlling a vehicle air outlet device to operate in a first working mode when the vehicle window reaches the instantaneous fogging condition; and the first working mode comprises a first
air volume level, a first air output mode, a first air inlet mode and a first
operation time. The anti-instantaneous-fogging
system for the vehicle window glass, the anti-instantaneous-fogging method therefor and the vehicle have the advantages of preventing the instantaneous fogging of the window glass, effectively improving the vision
clarity of a driver, and improving the safety of driving.
