So that hidden malfunction and safety issues can be found and avoided in time. Depending on computer communication technology、GPS(Global Position System)technology and GPRS(General Packet Radio Service) technology, Vehicle coordination is carried out. Vehicle’s on-line detected information is displayed and stored according to its position. Malfunction of vehicle’simportant parts can be alarmed in time combining with vehicle position where it happens. Vehicle’s information and history data can also be inquired in the database. With GPRS technology, data can be transmitted wirelessly to ground station and can be shared by others by connecting to the ground station. The function of main parts and its actualizing are referred. Besides these, the establishment of running-gear’s malfunction model is discussed. The practicability and  reliability of the monitoring system are proved by experiments on real run. The malfunction criterions of some parts can be improved by more experiment data to improve the whole system. Key words：Vehicle monitoring; GPS; GPRS; Running safety; Malfunction alarming; Running gear
