In order to accurately evaluate vehicle movement stability, a test system for vehicle movement stability based on real time kinematic （RTK） differential GPS technology is successfully developed. Vehicle movement parameters, which represent the vehicle motion performance, can be acquired in real-time with this test system, thereby achieving vehicle movement stability testing and evaluation. In addition, a superior approach for measuring vehicular velocity is contrived, which solves the difficulty in verifying the accuracy and precise of velocity measuring with GPS. The hardware composing and software flow are introduced. The real vehicle experiment results indicate that the test system for vehicle movement stability is feasible and advanced.
