Automobile electric control unit calibration system and method based on ASAP standard

The invention provides an automobile electronic control unit marking system and a method on the basis of ASAP standard, relating to the field of automobile electronic control technique. The ASAP standard is adopted to describe the marking/monitoring data property; the map file of an ASAP editing module on the basis of ECU is used for generating an ASAP database which is used for describing the marking/monitoring data property; an upper host machine configures the working environment according to the ASAP database, uses a CAN bus to carry out communication with the ECU by an XCP protocol, emits a marking control command, receives the ECU monitoring data, carries out the display, storage and analysis of the monitoring data, and realizes the marking and the monitoring to ECU parameters. The method of the invention overcomes the defects that the existing marking method has nonstandard data management, is difficult to be adapted to the changes of the ECU types and the communication interfaces of the ECU and has poor generalization, and improves the generalization and the adaptability of the marking system, thus improving the efficiency of the marking operation.
