Problems solved by technology

[0014] The present invention aims at the defects that the automated testing tools provided by HIL manufacturers in the prior art cannot work in parallel and have no effective division of labor and cooperation mechanism. However, if the test scripts are written manually, the workload is heavy, it is not intuitive, and it is not conducive to the defects of review and communication.

Abstract

The invention discloses an automatic execution method for an HIL test, which comprises the following steps of: formulating an interface interaction specification, specifically setting a consistent variable between a test case file and a test project, and appointing an ECU hardware channel pointed by a test equipment board card for executing the variable; according to the interface interaction specification, a test case file is designed, and the test case file comprises an action type and specific execution content corresponding to a variable in the interface interaction specification; test engineering configuration is completed at the same time, namely, alias mapping associated with the variables in the test case is added, and the alias mapping comprises variable names and hardware channels in the corresponding test engineering; and analyzing and executing the test case, specifically reading the file content of the test case, and calling a corresponding ActiveX read-write function to execute the test case according to the hardware channel in the alias mapping corresponding to the variable in the test case. According to the method, the configuration debugging work and the test case design work of the test equipment can be separated, so that the efficiency is improved.

Description

technical field [0001] The invention relates to the field of automobile testing, in particular to an automatic execution method for HIL testing. Background technique [0002] Hardware-in-the-Loop (HIL) is a development and testing technology for complex equipment controllers. Through HIL testing, the physical part of a machine or system is replaced by an emulator and is widely used in the development of automotive controllers. In the development process of ECU (Electronic Control Unit, that is, on-board computer), the system software and mechanical hardware structure are usually designed in parallel. Test work can only be carried out after integration. If some serious risk security bugs are discovered after integration, there is the potential for personal injury, damaged equipment, and project delays. To reduce the occurrence of these bugs, HIL testing has received extensive attention. [0003] At present, the automotive testing industry mainly realizes automated testing...
