Thermal comfort depends on various factors besides body surface temperature, although body surface temperature is an important factor. You can refer to ASHRAE handbook for the correlations, I think.

Thank you @chuan zhang for your interest. I known not only surface temperature is important parameters for thermal comfort and also air velocity, air temperature and relative humidity. But mine doubt is especially on IR thermography. Is it a best way to find surface temperature in an automobile cabin or have any other way or method or device or equipment.
If you want to determin the surface temp. I think is ok. However, in terms of thermal comfort is different than the surface temp. As you know.
Best wishes
Thermography from inside provides a mapp of the surface température that may help (together with air temperature and air velocity), in determining the operative temperature and draught risk.
It is however much simpler to use either a Bruel & Kjaer comfort-meter or comfort logger, or even cheaper to measure directly a good approximation of the operative temperature by putting a temperature sensor or a thermometer in an opaque, black painted ball about 10 cm diameter.
Thank You @Claude-Alain Roulet for your response.
But Bruel & Kjaer comfort-meter is looks traditional meter of thermal comfort. When i was searching about this meter, its established since on the year 1982. Did this instrument make easy comfort to work inside the vehicle cabin?
I don't klnow if this instrument is still available, but I often used it for comfort measurements and I think it can provide reliable measurements even in a vehicle cabin. Note that it is affected by air velocity but does not provide the draught risk!
This instruments needs 220 V 50 Hz, so a converter is needed if you want to use it in a mobile vehicle.
Thank You @Claude-Alain Roule for your valuable information and also learn lot of thing about comfort meter. I will consider for my research.
