Then, through simulation using the three - dimensional model, the simulated long - wave radiation heat flux density between each part of the human body surface and the surrounding environment, the simulated radiation heat transfer coefficient of each part, and the simulated human skin temperature are calculated. And the simulated long - wave radiation heat flux density, the simulated radiation heat transfer coefficient, and the simulated human skin temperature between each part of the human body surface and the surrounding environment are substituted into the preset heat radiation calculation formula to inversely deduce the surface temperature of each part of the human body surface; the historical outside - vehicle air temperature and the historical inside - vehicle air temperature of the vehicle under the preset test conditions are obtained. For each part, the surface temperature of the part is respectively fitted with the historical outside - vehicle air temperature and the historical inside - vehicle air temperature into a corresponding functional relationship, as shown in formula (2), and the functional relationship corresponding to the part is solved to obtain the temperature coefficient corresponding to the part.

[0062] T sr,m = αT out + βT in (2)

[0063] Wherein, T out is the historical outside - vehicle air temperature, T in is the historical inside - vehicle air temperature, and α and β are temperature coefficients.

[0070] S204: Determine the current skin temperature and core temperature of the target user through a preset thermophysiological model according to the current radiative heat transfer coefficient, current surface temperature, current environmental parameters, and current vehicle speed of each part.

[0071] In the embodiment of the present application, a preset thermophysiological model and a thermal comfort model are pre-set in the air-conditioning controller, so that after determining the current surface temperature of each part of the target user, the current surface temperature of each part, the current vehicle interior temperature, the current vehicle interior humidity, the current wind speed, and the current solar radiation intensity are input into the preset thermophysiological model; the preset thermophysiological model determines the current skin temperature and core temperature of the target user according to the input current radiative heat transfer coefficient, current surface temperature, current vehicle interior temperature, current vehicle interior humidity, current wind speed, and current solar radiation intensity of each part.

[0079]

[0080] where h R1 is the current radiative heat transfer coefficient of this part, σ is equal to 5.67×10 -8 W·m -2 ·K -4 is the Stefan-Boltzmann constant, ε sf ψ sf-sr is the model parameter of this part, is the historical human skin temperature, is the current surface temperature of this part, ε sr is the emissivity of the cabin interior trim.

[0081] It should be noted that the emissivity ε sr of the cabin interior trim can be taken as 0.95 and can be selected according to actual applications, which is not limited in the embodiments of the present application.

The specific calculation method is shown in formula (6). Finally, the radiation amounts of each part are summed to obtain the total human radiation amount of the target user.

[0086] Q = Aq R1 (6)

[0087] Wherein, Q is the radiation dose corresponding to this part, A is the area corresponding to this part, and q R1 is the current long-wave radiation heat flux density of the part.

[0088] In this embodiment, after the preset thermophysiological model determines the total radiation dose of the human body, it can further determine the current skin temperature and core temperature of the target user according to the total radiation dose of the human body, the current vehicle interior temperature, the current vehicle interior humidity, the blower gear, the current wind speed, and the current sunlight radiation intensity.
