No. 66 is known. The device comprises a device for forming a visibility-dependent signal. For this purpose, it has a sensor that detects the light that illuminates the vehicle from the rear and forms a signal that depends on the intensity of the detected light. This signal is a measure for visibility. This light may be terrestrial light coming from the sun, road lighting or artificial light sources emitted from other vehicles or the like. In addition, the device has an evaluation device, which processes the signals of the sensors representing the visibility. Depending on the result of the signal processing, the evaluation circuit controls the light emission of the fog lamp, here the rear fog lamp, as required for the respective visibility.
The strong light emission of the rear fog lamps then identifies the vehicle for subsequent traffic when the visibility is very low, and does not dazzle the following traffic when the visibility is relatively high. This is because the light emission is reduced. However, the intensity of the light emitted from the surroundings and arriving at the sensor is only suitable for detecting the visibility. This is because in this case there is an effect due to the general intensity of the light (for example depending on the time of day), which effect does not depend on the visibility reducing effect of the fog. Therefore, the visibility detection accuracy is very low, so that the light emission of the rear fog lamp cannot be accurately controlled, and the illusion of the following traffic cannot be ruled out.

される。In order to control the light emission of the fog lamps 10, 12 in a visibility-dependent manner, a device is provided which has the visibility detection device shown in FIG. The visibility detection device has a sensor 14, which is arranged in the region of the interior rearview mirror 16 of the motor vehicle. A transmitter 17 for transmitting an optical beam 18 in a predetermined wavelength region is also arranged in this region. The optical beam may be in the infrared wavelength region, for example, and is emitted from the transmitting unit 17 obliquely upward in the traveling direction of the automobile. The sensor 14 has a receiver 20,
The receiver is sensitive to the optical beam in the predetermined wavelength range. The receiver 20 is, for example, the photodiode 2
1, the optical beam is imaged on this photodiode by the optical system. In this photodiode, free electrons are generated depending on the intensity of the optical beam 19 that reaches it. This free electron causes different currents. The optical beam sent from the transmitter 17 exists in the atmosphere, and a part of the optical beam is reflected by the receiver 20 due to water droplets forming fog. The thicker the fog is, the more optical beams are reflected, the more free electrons are generated in the photodiode, and the larger the current flowing through the photodiode of the transmitter 20 is. The receiver 20 of the sensor 14 is connected to the evaluation device 24 via a current circuit 23. The evaluation device controls the light source 13 of the fog lamps 10, 12.
The evaluation device 14 detects a signal for the current intensity, which is dependent on the current circuit of the photodiode, for example, and thus the optical beam intensity reflected by the fog 22, ie visibility. The evaluation device 24 stores associated parameters for controlling the light source 13 for various values of the current intensity. Here, the actual current intensity is compared with the stored current intensity value by the comparator, and the light source 13 is appropriately controlled by the evaluation device 24. When the visibility is small, that is, the current intensity is large, the light source 13 is controlled so that the light irradiation is as large as possible. On the other hand, when the current intensity decreases as the visibility increases, the light irradiation of the light source 17 decreases.

Alternatively, an optical resistance can be used that changes its electrical resistance depending on the intensity of the incoming optical beam. In this case, the voltage drop across the optical resistance current circuit is evaluated as a measure for the intensity of the reflected optical beam.

In this case, the evaluation device 24 controls the operation of all the light sources 13 when the visibility is small, and controls the operation of the light source 13 which is relatively small as the visibility increases. If the visibility is so great that it is not necessary to activate the fog lights 10, 12, then none of the light sources 13 is correspondingly controlled.

The light emission of the light source 13 then depends on the duration of the voltage pulse. The longer the voltage pulse, the larger the working voltage applied to the light source 13, and the larger the light irradiation of the light source 13. The duration of the voltage pulse is controlled by the evaluation device 24 so that the light irradiation of the light source 13 is adapted to the visibility. When the visibility is low, the duration of the voltage pulse is optionally extended to a continuous voltage and reduced with increasing visibility.

The pointing device 26 is connected to the evaluation device 24. In the evaluation device, in addition to the parameters for controlling the light source 13, the values of the visibility assigned to various values of the current intensity generated in the evaluation current circuit 23 are stored. If the evaluation device 24 is additionally configured accordingly, it is possible for the evaluation device to store the respective running speed values for the current intensities representing different visibility. This traveling speed value is also instructed to the driver on the instruction device 26 as a recommended value. In this way, the driver can be instructed to maintain the maximum allowable traveling speed for each visibility, and the legal maximum speed of 50 km / h can be maintained when the visibility is 50 m or less.
