Automatic generation method and device of security level test scene library

Abstract

The invention discloses an automatic generation method and device for a security level test scene library. The method comprises the steps of collecting data through different data sources, a step of extracting a time signal from an industrial personal computer, performing data time synchronous fusion to form a unit data set, and importing the unit data set into a scene library, a step of systematically decomposing and classifying the unit data set to obtain scene factors, a step of recombining different scene factors obtain arrays, wherein each array corresponds to one scene, and a scene set is formed, and a step of and removing invalid scenes to obtain an effective diversified scene library. The method and the device have the advantages that the method and the device are universal and aresuitable for safety level test scenes of various vehicle types, the scenes are diversified, various similar scenes are automatically generated, the reliability is high, the error correction performance is reasonable, the invalid scenes are eliminated, the benchmarking test efficiency is improved, and the test cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile safety level testing, in particular to a method and device for automatically generating a safety level testing scene library. Background technique [0002] As active safety systems play an increasingly important role in improving the ride comfort and driving safety of modern vehicles, the demand for the development and application of active safety systems is becoming more and more urgent. In addition to the research on active safety system functions and algorithms, testing and evaluation, as an important link in the development of active safety systems, can detect product problems in time, ensure the correctness and reliability of system functions, and effectively improve product development efficiency. [0003] The test scenario can transform the test requirements of the product into a test process with practicability and operability, which is convenient for verifying the rationality of the pr...
