Abstract
Nothing is more irritating for drivers to see ever changing ghost images of himself and passengers reflected from windshield against the dark sky in the night. This image is greatly dependent on shape and arrangement of front glass. Interrelation between shape of front glass and ghost image was looked into by computer simulation to help solve this problem. As the results of vehicle test and simulation were very well matching the simulation calculation method is to be used for study of development of the next new model. (A)
