Problems solved by technology

Moreover, in the process of product development, it is also necessary to frequently change the application layer software and underlying software in the controller, so it is also necessary to use this tool frequently to generate a2l files for the calibration tool to create variable databases, and sometimes it is also necessary to perform calibration work according to the actual situation. It is necessary to make some modifications to the a2l file. Due to the many variables involved, the process of modification has become an extremely mechanized and labor-intensive task.
Therefore, the main defects of the current a2l generation method are: the reliability of the a2l file is low, the scalability is poor, and the portability is poor

Abstract

The invention discloses a user configurable device and a method of automatically generating an a2l file. The device and the method solve the problems generated in a calibration database configuration process. The invention adopts the technical scheme that a man-machine configurable interface is provided to perform generality predefinition configuration on the a2l file to be generated; configuration items are assigned to corresponding program data interfaces in a software service running process; software can automatically call the program interfaces in the running process to achieve a desired user configuration effect.

Description

Technical field [0001] The invention relates to the technical field of automobile controllers, and in particular to a method and device that can implement a user-configurable mode according to the characteristic differences of each controller chip platform and integrated compilation environment to realize the automatic generation of a2l variable database files. Background technique [0002] The a2l file is a calibration database file, which includes information about the calibration variables, the type, address, physical conversion method, and unit of the measured quantity. It is used to create a variable database file that needs to be imported before the calibration database is established in the calibration tool such as INCA or CANape. It follows the ASAP2 protocol. The address mapping file (.map) generated by each manufacturer's controller platform and its corresponding compilation environment are also different, so in the controller development project of the OEM, it needs to...
