In view of the problem that the present automobile fault detection was bad in the real-time detection and data was not conven-ient for unified management and so on,used the GPS,GPRS and CAN field bus technology to design a set of automatic control system. In this design,use the NXP Cortex-M3 core LPC1768 as central controller,use the Gstar GS-89 GPS module for vehicle positioning, LPC1768 comes with CAN bus collected the vehicle parameters. The data was transmitted through the GTM900-C wireless communica-tion module,which combined with the embedded programming ideas to complete the remote fault diagnosis controller software design. The experiment shows that using the design can realize the automobile information collecting and data processing,meeting the design re-quirements.
