This vehicle synchronization simulation device and means is provided with: a means for calculating positional information of the own vehicle; a means for transmitting the own vehicle positional information to a server means; a means for converting the own vehicle positional information into a specific data format and transmitting the same; a means for transferring the data via a network or a transmission bus inside of a specific device; a means for receiving the data and generating an image; a means for recognizing and detecting a specific object from the generated image; and a means for changing/correcting positional information of the own vehicle using the information resulting from recognition. The server means is provided with a means that synchronously controls three means, a own vehicle position calculating means, a transmitting/receiving means, and an image generating/recognizing means.
