Embodiment Construction
[0023] The technical solutions of the present invention are specifically described below in conjunction with the embodiments. The present invention discloses a vehicle-mounted 3D sunlight sensor, which combines Figure 1-Figure 2 As shown, similar to the prior art, they all include a casing, and a chip is arranged in the casing. The difference from the prior art is that four photosensitive elements are arranged on the chip, which are respectively the first photosensitive element 1 , the second photosensitive element 2 , the third photosensitive element 3 , and the fourth photosensitive element 4 . In this embodiment, the cross-section formed by the four photosensitive elements juxtaposed to each other in pairs is quadrilateral. A receiving hole 5 for passing light is opened on the housing, so that each of the photosensitive elements partially receives sunlight through the receiving hole. In the present invention, the section of the receiving hole 5 is circular. A vertical gap...

The invention provides a vehicle-mounted 3D sunlight sensor which comprises a shell, a chip is arranged in the shell, four photosensitive elements are arranged on the chip, a receiving hole for light to pass through is formed in the shell, and a vertical gap is formed between the shell and the photosensitive elements. The vehicle-mounted 3D sunlight sensor has the advantages that the sensor can accurately position the direction of the sun, then the temperatures of different seats in an automobile are judged, and therefore the air outlet amount of air outlets in different positions of the air conditioner is accurately adjusted, and the riding comfort of drivers and passengers is greatly improved; and meanwhile, resource waste caused by unreasonable distribution of the air blowing amount of the air conditioner is reduced, and vehicle energy consumption is reduced.
Description
technical field [0001] The invention relates to a vehicle-mounted 3D sunlight sensor and a photosensitive temperature regulation method thereof. Background technique [0002] With the improvement of people's living standards, cars have become an indispensable means of transportation for people. The sunlight sensor receives sunlight infrared rays through the photosensitive element to judge the intensity of the current sunlight. The sensor transmits the sunlight intensity signal to the car air conditioner control unit, and the control unit then controls the air conditioner to blow air and adjust the temperature in the cockpit. Existing sunlight sensors can only judge the intensity of the sun's infrared rays or the position of the sun, but cannot identify the specific elevation and azimuth angles of the sun in the sky, so they cannot accurately control the blowing position and air volume of the air conditioner. Increase vehicle energy consumption. Contents of the invention ...
