摘要： The invention relates to an optical sensor for motor vehicles for detecting a wetting of a surface. Said sensor comprises a measurement section which has at least one transmitter and at least one receiver for electromagnetic waves and in which a windscreen is positioned. Said windscreen influences the propagation of the waves between the at least one transmitter and the at least one receiver in such a way that when condensation forms on the windscreen, especially due to wetting caused by precipitation, an output signal generated by the receiver is modified. The optical sensor comprises a housing which is positioned on the inside of the windscreen and is characterized in that a base surface (18) of the housing (14) which contacts the windscreen is oval in shape.

摘要： The invention relates to an optical sensor for motor vehicles for detecting environmental parameters having an impact on visibility. Said sensor comprises at least one transmitter and at least one receiver for electromagnetic waves (light waves). A windscreen is positioned in a measurement path between the at least one transmitter and at least one receiver and influences the propagation of the waves between the at least one transmitter and the at least one receiver in such a way that when condensation forms on the windscreen, especially due to wetting caused by precipitation, an output signal which is generated by the receiver and serves to control a windscreen wiper device is modified. The invention is characterized in that at least one of the receivers (16, 20, 22) of the optical sensor (4) receives electromagnetic waves (light waves) of an ambient light of the motor vehicle and is used to control a lighting system of said motor vehicle.
