Embedded Data Acquisition in Vehicle Electronic System

The embedded data acquistition technology in vehicle electronic system was discussed. This technology adopts the parallel working mode , gets vehicle electronic system data by com-munication. This technology can provide us a lot of information on the electronic control unit , is very useful for the development of the vehicle electronic system , and can be used in diagnosis. The key points to this technology are the timer interrupt , A/ D interrupt , communication inter2 rupt and real time operation. This technology has been validated by the application in the elec-tronic control mechanism transmission shifting system of the tank.
