Example Embodiment
[0020] The ASAP standard is a set of matching calibration specifications. The ASAP standard is mainly composed of three parts, namely ASAP1, ASAP2, and ASAP3. As the interface standard between the application layer and the control device, the ASAP1 part defines the physical and logical connection between the application system and the ECU, and realizes the unified management of the upper and lower communication of the matching calibration system. XCP is a kind of ASAP1a. The ASAP2 part realizes unified management of all calibration data, monitoring data, interface information, etc., standard and standardized description of ECU functions, interfaces and calibration information, and the ASAP description file (*.a21 file) generated according to this standard is used as calibration The database of the system. The ASAP2 standard uses the ASAP2 meta-language A2ML (ASAP2Meta Language), and uses structured text to describe monitoring and calibration parameters and their interface information
