Problems solved by technology

[0003] In the current automotive engine performance calibration technology, it is still impossible to automatically screen out the specific operating conditions of the vehicle from the test record files (log files and / or .dat files, etc.). To run the working condition log, you need to use special software to open the log file, and manually observe the vehicle speed signal, starting temperature, downtime and other data, which is laborious and laborious, and it is not convenient for the analysis of large data volumes, which also leads to the performance calibration efficiency of automobile engines.

Abstract

The invention provides an automobile working condition screening method, an engine calibration method and system and a readable storage medium. Specific working conditions (namely specific automobileoperation working conditions) can be automatically screened out from a large number of collected data record files of different test types, the scheme is reliable, simple and efficient, and generationof a test report, statistical analysis of big data and accurate calibration of an engine can be facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile performance calibration, in particular to a method for screening automobile operating conditions, an engine calibration method and system, and a readable storage medium. Background technique [0002] As cars become more and more popular in our lives, more and more people are interested in car engines, because the engine is the heart of the car, and the quality of the engine directly affects the quality of the car. Before the engine is used in the actual vehicle, it is necessary to develop various performance indicators of the engine (including engine, vehicle, system algorithm and control strategy, and determination of peripheral devices), and perform performance calibration on the engine to make the engine more perfect Work. Among them, the performance calibration of the engine usually carries out various corresponding tests on the car. By adjusting and measuring the control parameters of the...
