US Patent 8010283 Driving evaluation system and server

Travel information of a target vehicle is stored in time sequence and, on the basis of the travel information and pre-stored travel information of a professional driver's vehicle, a travel position of the target vehicle and a travel position of the professional driver's vehicle are displayed in animation. In such a manner, the driver can visually recognize the travel positions of the displayed target vehicle and the reference vehicle and understand how much the target vehicle is deviated from the ideal travel position.
