The invention relates to the technical field of vehicle calibration electric appliance systems, and particularly discloses a method for importing calibration quantity and observed quantity information through A2L file fusion, which is characterized in that model logic
processing, calibration quantity and observed quantity are created and realized through a
model building tool Simulink, and the calibration quantity and observed quantity information is perfected. Information in the two A2L files is fused through ASAP2, and scaling quantity and observed quantity address information in the ELF file is generated through a
software integration tool and updated to the fused A2L file; compared with a traditional mode of directly compiling the A2L file, the method is faster and more accurate, the requirement for professionals is not high, and the development time is saved. Compared with a mode of extracting the calibration quantity and the observation quantity through an ELF file, the method has the advantages that the remark information of the calibration quantity and the observation quantity is more complete, professionals have better
cognition on the calibration quantity and the observation quantity, and the calibration process can be better achieved.
