Two years ago Polyphony Digital and Toyota Motor Corporation announced a new technology that would allow data from a real car driven on a real course to be logged and visualized in Gran Turismo 5 for testing and display purposes.
The system exports CAN (Controlled Area Network) and GPS data recorded in a real car to a USB memory stick and feeds it to Gran Turismo 5’s simulation engine, producing a replay or recreation of that data within the game.
The data can be used as a ghost car, or used to analyze the real-life performance of a driver or a car on the race track.
CAN data includes things like forward/aft and right/left G forces, steering, brake, accelerator operations and engine rpm, as well as the rotational speeds of each wheel. When combined with GPS positional data, a very accurate recreation of the recorded drive is possible.
Sounds interesting, doesn’t it? Now you can actually see it in action past the cut in a recording from the Japanese TV, as the engineers of Polyphony and Toyota test the system on a Toyota F-86 and Kazunori Yamauchi races a real life driver on a PS3.
