Fog detection method
First Claim
1. A fog detection method in a vehicle, comprising:
- emitting a first encoded optical signal into a vehicle'"'"'s surroundings via a first fog sensor with a first transmitter;
receiving the first encoded optical signal reflected from the vehicle'"'"'s surroundings via an associated first receiver;
decoding, analyzing, and providing a first detection result related to the reception of the first encoded optical signal by a first analyzing unit;
wherein for the encoding of the first encoded optical signal, a code is selected among a plurality of possible codes (A,B,C) by the first transmitter and the code selection is communicated from the first transmitter to the first receiver or to the analyzing unit, wherein in analyzing the signal received by the first receiver through the first analyzing unit, the code selection for identifying the first encoded optical signal in the received signal is used.

Abstract
The present disclosure relates to a fog detection method in a vehicle comprising the steps of: providing a first fog sensor with a first transmitter emitting a first encoded optical signal into a vehicle'"'"'s surroundings, and an associated first receiver for receiving an optical signal reflected from the vehicle'"'"'s surroundings, and a first analyzing unit for decoding, analyzing and providing a first detection result related to the reception, wherein, for encoding, a code is selected among a plurality of possible codes (A,B,C) by the first transmitter in a code selection, and the code selection is communicated from the first transmitter to the first receiver and/or the analyzing unit, wherein, upon analyzing the signal received from the first receiver by the first analyzing unit, the code selection is used for identifying the first encoded optical signal in the received signal.
