Device and method for automatically preventing misting of the windscreen of a vehicle
First Claim
1. A device (1) for preventing misting of the windscreen (2) of a vehicle (3) having a passenger compartment (5), comprising:
- sensor means (4, 6, 7) for detecting ambient conditions capable of misting said windscreen (2) and supplying information regarding said ambient conditions; and
intervention means which receive said information from said sensor means (4, 6, 7) and are activated automatically, upon said ambient conditions occurring, to prevent misting of said windscreen (2), whereinsaid sensor means (4, 6, 7) comprise radiant mean temperature sensor means (4) arranged inside said passenger compartment (5) to measure temperature (Ti) inside the passenger compartment (5), said radiant mean temperature sensor means (4) having a field of view including at least part of said windscreen (2).

Abstract
A device and method for automatically preventing misting of the windscreen of a vehicle, wherein a number of sensors determine ambient conditions capable of misting the windscreen, and, upon such ambient conditions occurring, an electronic central control unit automatically activates the air-conditioning system of the vehicle to prevent the windscreen from misting. The device has and the method utilizes a radiant mean temperature sensor arranged inside the vehicle passenger compartment to measure temperature inside the passenger compartment. The radiant mean temperature sensor (4) has a field of view including at least part of the windscreen.
