Sunshine penetration photosensor G107 The air-conditioning temperature control is affected by the sunshine penetration photosensor. It measures the sunlight falling directly on the car’s occupants.

How it works: The sunlight impinges on a photodiode through a filter and an optical element. The filter has the same effect as sunglasses and prevents sublight from damaging the photodiode. The photodiode is a light-sensitive semiconductor element. When it is not illuminated, only a small electric current can flow through the diode. When it is illuminated, the electric current increases. The stronger the light, the higher the current.

To the control unit, an increase in electric current indicates higher sunshine penetration. It regulates the interior temperature accordingly.

Diagonal sunlight penetration
Particularly sunlight incident on the car’s occupants diagonally from the front, i.e. directly, increases the feeling of warmth. The optical element deflects a large proportion of diagonally penetrating sunlight onto the photodiode. Cooling is increased to equalise the effect of heat radiation on the body.

Vertical sunlight penetration
Vertically incident sunlight is screened by the car’s roof. The optical element deflects less light onto the photodiode. Cooling can be reduced as the car’s occupants are not directly exposed to heat radiation.
2013/8/18(日) 午後 3:41
Effects of signal failure No replacement function. Self-diagnosis fault message Open circuit/short circuit to positive. Short circuit to earth.
The temperature of the air streaming into the vehicle is now measured by two separate temperature sensors.

The air-conditioning temperature control is affected
by the sunshine penetration photosensor.
It measures the sunlight falling directly on the
car’s occupants.
