A project is put forward to implement performance testing on vehicle under traffic condition, based on lower computer with storage test, as an aid subsystem of the platform test system. The performance and functional requirements are given. The similarities and differences are analyzed, between this system and lower computer with traditional storage test, and between this system and lower computer used in industry. Basic framework and working principles are given. Main technical points are analyzed. It shows that the project is feasible in principle, and its function can be realized with existing technology. But there are still quite a few technical details in the system to be considered during development, with the focus from low power consumption, and high reliability optimization design of circuit.
