Calibration apparatus and method based on one kind of automotive electronic control units of the protocol ccp

The present invention provides a method for calibration of automotive electronic control unit based on CCP, S19 reads the file of the first current memory, each address mapping calibration parameters and initial values ​​stored in a recessive manner write a dominant the second file S19; S19 parsing the second file, obtain the calibration parameters for each mapped address and the initial value, after receiving the calibration command, the electronic control unit to treat auto-line calibration the calibration process, the calibration line obtained through calibration process parameter values; the initial value of each parameter of the first scaling the current memory file replace S19 after the processing of each line calibration the calibration parameters. Embodiment of the present invention, can reduce the complexity of automotive ECU calibration system, and reduce production costs and labor costs.
