The invention relates to a system for judging a driving right of a driver. The system at least comprises a mobile terminal and a vehicle device equipped with vehicle-mounted equipment, and performs data exchange with the vehicle-mounted equipment, which is at least provided with an identification module, a first authentication module, a second authentication module and a third authentication module, by using the mobile terminal, so as to judge a usage right of a user to a shared automobile, wherein the identification module generates a first risk parameter based on personal information of the user; the first authentication module generates a second risk parameter based on historical driving information and real-time physiological information; the second authentication module generates a third risk parameter reflecting the actual driving ability of the user by showing simulated roadway information to the user and collecting feedback information from the user; and the third authentication module generates a fourth risk parameter based on the first, second and third risk parameters to evaluate a safe driving level of the user and determine the driving right of the user when the user uses the shared automobile based on the safe driving level.
