The invention provides an intelligent vehicle long tunnel outlet GPS drift section control system and a method thereof. The system comprises a GPS/INS combination guidance system, a gyroscope inertial navigation system and an intelligent vehicle decision-making system. The GPS/INS combination guidance system and the gyroscope inertial navigation system provide first and second GPS positioning data to the intelligent vehicle decision-making system. The intelligent vehicle decision-making system calculates first and second positioning data instantaneous vector increments according to the obtained two groups of GPS positioning data, judges whether the GPS/INS combination guidance system is in the normal state or not according to the difference between the first positioning data instantaneous vector increment and the second positioning data instantaneous vector increment, and selects one of the first and second positioning data to formulate an intelligent vehicle control scheme for intelligently controlling vehic
