Automating HIL test setup and execution

This paper describes an overview of the integrated test system for insuring interoperability of the various Electronic Control Modules (ECUs) of the electrical bench sub systems. This system has the following primary objectives: (1) To configure the electrical system bench using the existing configuration files for each wiring harness , Electronic Control Modules (ECU) and various devices/components, (2) To automate the integrity testing of the system bench, (3) To design a test executive for multiple test procedures for a bench that will be executed in unattended mode for long periods of time, up to several days, (4) To create a data repository for all files associated with a particular bench including; test procedures with test parameters, device configuration files, application description files and ECU flash files, (5) To utilize a standard, open architecture that allows for effortless swapping of hardware devices and software applications in the future to reduce or eliminate vendor dependence, (6) To increase the amount of automation possible by allowing multiple software applications and devices to freely communicate between one another and allow devices to control other devices.
