As is shown by way of example in fig. 2, the temperature sensor 40 is arranged in the interior of the vehicle 100, for example close to a windshield or an interior rear view mirror, and the temperature sensor 40 is provided for detecting the temperature inside the vehicle 100. However, it is alternatively contemplated that the temperature sensor 40 may be disposed at any location of the vehicle 100 suitable for detecting the temperature inside the vehicle 100, such as a roof, a center console, and the like. Alternatively or additionally, the temperature sensor 40 comprises an infrared camera arranged for detecting a body temperature distribution of a passenger in the vehicle 100. In this way, the angle of the air outlet of the air conditioner can be adjusted in a targeted manner, air is supplied to a part where the temperature difference between the body of the passenger and the target temperature is large, for example, cold air is distributed to the body part with the highest temperature of the passenger in the cooling operation, and therefore the body temperature of the passenger can be adjusted to the comfortable temperature more efficiently.
As exemplarily shown in fig. 2, the image sensor 50 is arranged within the interior space of the vehicle 100, for example, close to a windshield or an interior rear view mirror, and the image sensor 50 detects the position of a passenger within the vehicle 100 and the bare skin of the passenger, for example, the face, the arm, etc. However, it is alternatively contemplated to dispose the image sensor 50 at any location of the vehicle 100 suitable for detecting the passenger position as well as the exposed skin of the passenger, such as the roof, center console, and the like. In particular, the image sensor 50 is a vision camera 50. By identifying the exposed skin of the passenger, the detected temperature at the exposed skin can preferably be taken into account, which improves the accuracy of the temperature detection. Alternatively or additionally, the image sensor 50 is capable of identifying a body part of the passenger, such as the head, torso, limbs.
