Implementing a vehicle model in the HILS environment allows you to perform a network integration test under the same conditions as in actual driving in a virtual environment before actual vehicle testing. In addition to the functional tests, electrical failure such as disconnection or short circuit and fault diagnosis such as communication error can be simulated in real time. From the development stage, various scenarios and algorithms can be applied to automate the test, thus improving the quality and stability of the finished vehicle and contributing to reducing time and cost. In the era of autonomous vehicles, vehicle systems play a greater role than drivers. Therefore, it is necessary to build a virtual testing environment to verify these vehicle systems.
- HIL TESTING BENCH implementation (real case)
Using TEST BENCH allows you to secure the performance, stability and reliability of the system through repeated and FIU tests in various environments. By reducing the number of prototypes early in the costly development process, you can significantly reduce development costs and time. This is a very effective method to implement multiple tests (functions, diagnostics, FIUs, repetition) in the laboratory.
We know how to configure and simulate a test system in a virtual environment.
