In this paper, the
infl uence of solar radiation direction and intensity on thermal fl ux on
passenger vehicle driver’s body was analysed. The analysis was carried out on a
virtual model of a vehicle cabin. The results showed that the highest heat fl
ux caused by solar radiation could occur when the sun is shining in the front
of the vehicle, as proposed in standard ISO 14505-2: 2008. Under these conditions,
driver’s chest is the segment with the highest heat fl ux. The unfavourable
situation due to highly asymmetric thermal condition is also when the sun is
shining on the left side of the cabin. From that reason, paying attention to
solar characteristics of glass and to design of air distribution system in such
way that air-conditioner vents can be directed to areas with the highest fl
uxes is an effi cient way to reduce the driver’s and passenger’s thermal stress.
This research was done
as a part of the project TR35041 - “Investigation of the safety of the vehicle
as part of cybernetic system: Driver-Vehicle-Environment”, which was supported
by the Serbian Ministry of Education, Science and Technological Development.
