A method and device for detecting address range conflicts of a2l calibration quantity

Abstract

The present invention provides a method and device for detecting A2L calibration quantity address range conflicts, constructs a calibration quantity list including the index number, name, start address and end address of each calibration quantity in the A2L file, and extracts the calibration quantity list in the calibration quantity list The address items construct the first address list, and sort the address items in the first address list according to the order of the address items from small to large to obtain the second address list, by comparing the first address item list and the second address item list The address items are compared line by line, which realizes the automatic detection of the address range conflict of the calibration quantity in the A2L file. If the first address list and the second address list are exactly the same, it is determined that the calibration quantity in the A2L file does not have an address range conflict; if There are differences between the first address list and the second address list, and the calibration quantities with address range conflicts are determined according to the mapping relationship between the index numbers of the difference items and the index numbers in the calibration quantity list.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a method and device for detecting conflicts in address ranges of A2L calibration quantities. Background technique [0002] At present, in the development process of automobile software, the software of the automobile electronic control unit needs to calibrate and measure the data. Calibration and measurement data are generally stored in ASAM MCD-2MC format, and the file name ends with .a2l, referred to as A2L file. [0003] When using A2L files for calibration or data synthesis, if due to some special reasons there are variables in the A2L file with duplicate address ranges or overlapping address ranges (that is, address range conflicts), then there are two variables with different names that are being operated. Variables, but the data of the same address is modified, that is, there is a potential problem of incorrect data modification, resulting in abno...

[0003] When using A2L files for calibration or data synthesis, if due to some special reasons there are variables in the A2L file with duplicate address ranges or overlapping address ranges (that is, address range conflicts), then there are two variables with different names that are being operated. Variables, but the data of the same address is modified, that is, there is a potential problem of incorrect data modification, resulting in abnormal operation of the ECU
