Recently, the time in which children moves by car become frequent, they stay longer in the car because leisure life including camping and etc. increased. Children whose physical activities are active were subject to restriction because of the limited car boarding visual space and on security. Because of limited space in cars, domestic and foreign automotive companies show the different glass roof applied in cars that exhibited wide clear view in order to remove tedious and stuffy of children while they stay for a long time inside the car. In addition, the potential probability in which the Smart Car that the IT technology is grafted research and research that it utilizes the door window glass as the display is progressed and which the glass roof can be used as the screen can be sufficient. In this study, the in-vehicle display application case and Smart Devices constellation application were benchmarked. The car glass roof application method of the constellation studying content which performed the user survey for the child by the car with the parents whose movement is frequent and considers the child and fundamental interaction way tried to be drawn and we try to propose.

A numerical simulation was performed of flow behind a squareback car with a rear spoiler. Influence of the rear spoiler on drag force has been studied. A lattice Boltzmann method was utilized to portray the unsteady aerodynamics of wake flows. The pressure distributions were employed to examine the vortex formation mode against the rear spoiler. It was found that the separation flow at roof end and c-pillar makes three dimensional vortex structures and the rear spoiler increases pressure on the rear glass surface.
